EDITORIAL

Apologies are doubtless due to readers who may have been confused by
the editor’s address printed in the Proceedings and membership card
during recent months. Selling a London flat and moving to the country
is not a smooth or swift process these days. There have been several slips
between the cup and the lip; one country address, too confidently proclaimed
on the inside cover of Vol. 10 (1/2), had to be abandoned to a rival when
two would-be purchasers of the flat in succession withdrew. As we go to
press the contract for the purchase of a future house has not yet been
signed and it seems safer to depend on my bank to forward contributors’
mail, even though this is a day or two slower. I trust that our next issue
will give an address not so subject to mutations as these last three.

The Society’s list of the Lepidoptera of the garden of Buckingham Palace
(not yet sold out! ) has shown that Central London has at least one habitat
where, if the only Monarch is the human one, not a few butterflies and
moths, with humbler but perhaps longer titles, have either survived from
rural days over two centuries, or have penetrated and colonised the royal
oasis; however, from the window of my Westminster flat, the most I ever
saw was a dancing male Vapourer Moth last August, nor had my abode
a balcony on which I might have set a Robinson trap, to draw from the
night sky one or two nocturnal fugitives from nearer gardens. The thirty-
mile move to East Berkshire, therefore, to water-meads, chalk downs and
beech woods, has been eagerly awaited, but having to be made in mid-
January, was entomologically unsatisfactory. About once a week the Natural
History Museum and the Society’s Rooms in Mayfair will draw me back
along the M4. This motorway may be one of the better arterials into the
metropolis; but my first morning’s trip was performed in a snow-storm,
and weather and traffic conditions left much to be desired. Things can
but improve from now on, I console myself.

Having arrived in the Cookham neighbourhood, there is one old acquain-
tance I am certain to find in the summer, if I but break open the seed-
heads of the garden hollyhocks, for I have found it there already: this is
the Gelechiid Pexicopia malvella (Hiibner), both a town and country moth:
I first took it in marshmallow flowers in the Waveney marshes on the
Norfolk-Suffolk border, and later in the hollyhocks of Vincent Square,
Westminster. I am sure, too, that Her Majesty, if she would like a specimen
of two, will find the creature in her hollyhocks, whether in her town
garden or that of her residence in East Berkshire.

THE 1977 ANNUAL EXHIBITION
(see Plates I and II)

The Annual Exhibition took place, as is customary, on the day imme-
diately after the Annual Dinner, that is on Saturday, 29th October, the
venue again being Chelsea Old Town Hall. The attendance exceeded the
previous year’s remarkably high figure, 350 members and visitors signing
the entry-book. One hundred and ten different exhibits, of which further
details are given below, were on show. Considering that the season had
been below the average for insects, these figures are remarkable and a
cause for satisfaction. As usual, a high standard was achieved by exhibitors.

BRITISH MACROLEPIDOPTERA

The display of Macrolepidoptera was remarkably interesting, the results
of the current poor season being supplemented by a large aftermath of
captures and rearing from the brilliance of 1976. Some 60 exhibitors, out of
about 100 in all, showed British Macrolepidoptera, either alone, or in a
dozen cases along with Microlepidoptera, foreign species, or exhibits of
other Orders. A few failed to provide notes, and their exhibits are not
recorded here.

Highlights were two Noctuid species new to the British list — Blepharita
solieri (Bdvy.) (fig. 12), a Mediterranean species whose arrival in a light-trap
in Roxburghshire is, even in such a year as 1976, hard to explain; and
Herminia lunalis (Scop.), whose normal range extends through France and
Belgium to the Netherlands and whose appearance in the Thames Valley
is less surprising. Besides these, there was a preliminary exhibit of a new
species or sub-species in the Thera group of Geometers; and among the
Rhopalocera an Erebia, stated to have been caught in the Scottish High-
lands in 1969, was recognised during the exhibition as an example of that
legendary British species Erebia ligea (L.), the Arran Brown (PI. II, fig. 11).

Immigrant species caught in 1977 were few; but they included a Coscinia
cribraria arenaria Lempke from Kent, a single Hyles lineata livornica (Esp.)
from north Lancashire, and two examples from Scotland of the many
Eurois occulta (L.) which invaded eastern Britain in 1977. Among 1976
captures not previously exhibited was a notable Trigonophora flammea
(Esp.) from West Sussex, with several other scarce immigrants.

The number and variety of aberrations was one of the striking features
of the exhibition. Some had been caught in the field, others were the
result of skilful selective rearing, or of temperature experiments. Among
the former, there was a remarkable collection of twelve major aberrations
of Argynnis paphia (L.) which had been caught in one wood during 1976
and 1977 (figs. 2, 3), an extreme underside Plebejus argus L. ab. striata
(exhibited on behalf of a non-member) (fig. 14), and a probably unique
banded aberration of Xestia castanea (Esp.) (fig. 4), as samples of many
good things. Among the results of selective breeding, some very fine
Hipparchia semele L. ab. holonops Brouwer (fig. 1) were conspicuous.

Exhibits of the scarcer resident species and of new county records were
thinner than usual; but it was interesting to see specimens in various
exhibits of the recently discovered Eriopygodes imbecilla F. (fig. 7) and all
three sub-species of Luperina nickerlii Frr. A curious specimen of Clostera
curtula L. bred from a larva found near Loch Ness is, if not the first

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 3

record for Scotland, by far the most northerly. Probable first captures of
Photedes extrema (Hiibn.) in Kent and of Leucochlaena oditis (Hibn.) in
Sussex were also shown.

Photographs and paintings both of imagines and of larvae were numerous
and good, and some new types of distribution maps were on view.

FOREIGN LEPIDOPTERA

Fifteen exhibitors showed foreign Lepidoptera, mostly Palaearctic, with
France as the predominant source. Miss M. L. ARCHER exhibited two dozen
species of Alpine butterflies from a visit to La Gorge de St. Pierre and
Allos, Hautes Alpes, in August 1977, including interesting Erebia and
Coppers. M. HapLey and M. J. Parsons showed the results of five weeks’
collecting at Chateau de Paron, Sens, Yonne, in July and August, including
many Heterocera caught in a Robinson light trap. R. F. BRETHERTON,
P. W. Crisp and R. C. Dyson showed representative selections of butterflies
caught during a six-man expedition to the French Massif Central, with
some stops during the journey there, from 4th to 16th July, an account of
which will appear in the A.E.S. Bulletin. About half of the 110 species
recorded were exhibited, some of the more interesting being Boloria
aquilonaris (Stichel), Lycaena helle (D. & S.), Scolitantides orion (Pallas),
Clossiana titania (Esp.), Melanargia russiae (Esp.), and local races of six
species of Erebia. All these were from the Massif Central; the very local
Hesperid Heteropterus morpheus (Pall.) was found in the Forét de Vierzon,
Cher, and, along with Apatura iris (L.) and A. ilia (D. & S.), in the Foret
de Rambouillet, Yvelines. G. N. Burton also showed species of Erebia
from Cantal, Massif Central, and Lysandra coridon (Poda), whose presence
in this purely “‘volcanic” area is surprising, collected in August 1977; he
also had various species from the Jaca district in north Spain. From that
country H. G. PHELPS exhibited a selection of Lycaenidae taken in May
and June 1976 and 1977, including possible hybrids between Lysandra
coridon asturiensis de Sag. and L. bellargus (Rott.), with bred specimens
of the latter’s f. ceronus Esp. S. E. WHITEBREAD showed a large selection
of Lepidoptera taken in Sicily and Calabria in August and September 1977,
mostly not yet identified but including species of Heterocera which are
familiar as immigrants to Britain. Completing the European exhibits, C. B.
Asupy showed a first instalment of a representative collection of Swedish
Macrolepidoptera which the Society has been pleased to accept from our
member in Stockholm, Stic TORSTENIUS.

From the Middle East, W. G. TREMEWAN showed a series of Zygaena
cambyses Led. and Z. tamara Christoph. reared in England ab. ovis Iran:
the life history of Z. cambyses was previously unknown. T. B. LARSEN
showed from Lebanon Maniola telmessia (Z.), an extreme ab., Tripoli;
Melitaea didyma libanotica Belter, female ab., Byblos; and an unidentified
Lycaenid, probably a hybrid, from the Cedar mountain; from Jordan,
Euchloe falloui Allard, Ras el Naqb, and E. belemia (Esp.), Ramtha,
species which are rarely sympatric; from Israel Jolana alfierii Wiltshire;
from Sinai Peninsula two recently described endemic species, Strymonidia
jebelia Nakamura and Pseudophilotes sinaicus Nakamura; from Morocco,
Gonepteryx cleopatra (L.), inter-sex, near Tetouan.

From the Nearctic zone L. J. Evans had an interesting collection of 32
species of butterflies taken in South Ontario, Canada, eight of which are
also on the British list: From Africa D. M. TREMBATH showed six drawers
of butterflies (104 species) from Kenya and two drawers from South Africa.
Among the rarer Kenyan species were Bematistes quadricolor Rog., Amauris
inferna Butler, Apaturopris cleocharis Hew., and various Cymothoe
Hubner. G. H. MaAnsett exhibited a fine selection of butterflies from
Malaysia.

Heinemann (possibly only a form of D. abietella (D. & S.) or D. mutatella
(Fuchs)), Bramley, Surrey, 1.ix.76, 21.viii.77; these (and others not exhibited)
appear to be identical with D. simplicella, figured and described as a species
new to the Netherlands in Ent. Bericht (1976), 36:98; the validity of this
as a good species is, however, disputed.

viously confused under tibialis (Meigen) but recently distinguished by Dr.
R. Rozkosny; tibialis which is darker in colour, is commoner and reaches
Yorks. and south-east Ireland, while the new species is southern but already
known from Kent/Sussex to Cornwall and S. Wales; one male of the latter
was reared from flood refuse by the River Test at Leckford, Hants.

(3) Some flies found in unusual associations at Windsor Forest, Berks.
during 1977: (a) Microsania species (Platypezidae), the well known Smoke
Flies, and Homopeza obliterata Zett. (Emphididae), a little known species

sexes of the latter settled on smouldering logs and their whitish wings made
them inconspicuous against the ash, in the pooter they preyed on Micro-
sania; (b) Astiosoma rufifrons Duda (Asteiidae), new to the British list,
numerous on cold bonfire ash, vi-vii, and at smouldering elm wood, Old
Windsor, 11.ix; (c) Chymomyza distincta (Egger) (Drosophilidae) on cut
ends of pine logs with C. fuscimana (Zett.), a commoner species, but also

during 1977; Eustalomyia histrio (Zett.) and E. vittipes (Zett.) (Antho-
myiidae), Crab Wood, 10/11.ix on dead beech trunk.

(2) Solva maculata (Mg.) (Xylomyiidae), 9.vii, settling on bracken and
a dead beech tree near Lyndhurst, Hants.; this striking insect is rarely
seen on the wing, most examples in collections like those exhibited by
P. J. Chandler (see above).

closely related species.

ACULEATE HYMENOPTERA

Ese, G. R. — Local and rare aculeate Hymenoptera collected in Hamp-
shire, the Isle of Wight and Lancashire during 1977. Among the 17 species
exhibited, the following six are perhaps of special note (all except the last
were collected on the Isle of Wight). Psen (=Mimesa) atratinus (Morawitz)
(Sphecidae): a pair in cop., Luccombe Chine, 20.vii. These are the second
and third British examples, the first was a 9 collected at Ladder Chine
—also on the Island—on 7.viii.1950 by O. W. Richards. Methocha
ichneumonoides Latreille (Tiphiidae): an example of the rare ¢, Luccombe
Chine, 20.vii; Nysson interruptus (F.) (Sphecidae): 2 @ 2, Red Cliff, nr.
Sandown, 3.vi; Sphecodes niger Sichel (Halictidae): 2 ¢ 2, 2 2 2, Black-
gang area, 21 and 28.vii. This small bee, an inquiline of certain small
Lasioglossum species (also Haltictidae) has always been very rare in Britain,
with apparently only three published records — East Sussex, Buckingham-
shire and Bedfordshire. In the British Museum (Natural History) there is a
male collected on Hampstead Heath in 1938 and a female from Ruislip,
1939. Another rare bee exhibited was a fresh @ Osmia xanthomelana
(Kirby) (Megachilidae): Luccombe Chine, 21.v. The only Lancashire speci-
mens were 3 @ @ Colletes cunicularius (L.) (Colletidae), a large bee much
resembling the common honeybee. Cunicularius is a speciality of coastal
dune slacks in north Wales, Lancashire and Cumberland. The specimens
were collected at Ainsdale, 8.iv.

Jones, R. A. — A display of various British insect Orders collected in
1977 included a selection of aculeates and one sawfly, the local XY yphidria
camelus (L.). The latter was a 9 from Heathfield, Sussex (no date available).
Aculeates were —also without dates —as follows: Myrmosa atra Panzer
(Tiphiidae): 1 2, Little Horsted, Sussex; Hedychridium roseum (Rossi)
(Chrysididae): 1, Kingstone Common, New Forest, Hampshire — the
uncommon inquiline of the Sphecid Astata boops (Schrank); Omalus panzeri
(F.) (Chrysididae): 1, Ringwood Forest, Dorset; and Eumenes coarctatus
(L.) (Eumenidae): a specimen of the ‘Potter Wasp’ from Kingstone
Common.

Mites, S. R. — A selection of aculeates from Odiham Common, north
Hampshire, 1977. These included two uncommon species. Astata boops
(Schrank) (Sphecidae): 1 @, 1.viii; Ceratina cyanea (Kirby) (Xylocopidae):
1 ¢, 1 &, ex-Rubus stems, 3.i. Cyanea has hitherto been considered a
rare bee, but a number of localities have been found for it in recent years
in Kent, West Sussex and Hampshire (mainly as a result of gathering dead
Rubus stems during the winter). During the spring the females excavate
the pith of dry dead stems and construct their cells in the linear gallery.
Burrows in the stems also act as hibernacula for both sexes.

PACKER, L. — Some interesting aculeates from Kent, 1977 and a selection
of inquilines and associated aculeate hosts from various British localities.
The following species collected in Kent are of interest (these are not
nationally rare but some are either specialities of, or of uncommon status
in the county). Omalus violaceus (Scopoli) (Chrysididae): 1, Herne Bay,

18 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

22.vi— collected in a garden as have the majority of British records;
Colletes halophilus Verhoeff (Colletidae): 1 &, Faversham, 7.ix, a bee
restricted to salt marshes in S.E. England; Andrena hattorfiana (F.)
(Andrenidae): 1, Lydden, nr. Dover, 19.viii, our largest Andrena, has a
preference for the flowers of Knautia arvensis L. A. apicata Smith: 1 ¢,
Bonnington, iv. Both the Andrenas are the first Kentish records since the
period 1900-19. Sapyga clavicornis (L.) (Sapygidae) was the most interesting
of the inquilines exhibited. The species was represented by a ¢ from
Heol-y-Gaer, nr. Hay-on-Wye, Herefordshire/Wales border, 5.vii. According
to the literature, this wasp is a cleptoparasite of Osmia species and Chelo-
stoma florisomne (L.), all Megachilid bees.

PARASITIC HYMENOPTERA

There were two main contributors to this order and the quality of the
exhibits reflected the growing interest in the Parasitica, helped not least
by the increasing co-operation of Lepidopterists in saving their parasites.
Amongst the more notable species shown were: Apanteles gades Nixon (a
first British record) bred from Stauropus fagi L.; Microplitis strenuus
Reinhd., bred from Diloba caeruleocephala L.; Astiphromma graniger
Thoms.; Cratichneumon albifrons Steph.; Absyrtus vicinator Thb.; Apha-
nistes xanthopus Shrk.; Cliocentrus excubitor Hal.; an unusually large
brood of a Litomastix species, and Sympiesis dolichogaster Ashmead (a
first British record).

ALLEN, A. A. — A selection of Ichneumonoidea both caught and bred
by himself, mainly during 1976-77. Omitting 13 species dealt with in our
Vol. 10 (1977) Proceedings, there were: Rogas testaceus Spinola: One of
several examples bred from Abraxas grossulariata larvae found at Salfords,
Surrey. The exhibited ¢ was bred 16.vi.76 from a host larva found on
Prunus spinosa, 9.v.76. Apanteles lacteicolor Viereck: A solitary species,
regularly obtained as a parasite of Nola cucullatella larvae. The specimen
shown was bred 21.v.76, from the aforementioned host found 9.v.76 at
Salfords, Surrey. Apanteles fraternus Reinhd.: Several adults, representing
a fraction of the total brood which hatched late July-early August 1977,
from the characteristic cocoon mass discovered on a grass stalk, 2.vii.1977
at Rye, Sussex. Protomicroplitis minuta Reinhd.: Six examples, from a
total brood of 61 adults, bred in June 1976 from a larva of Alcis repandata
obtained late March 1976, Salfords, Surrey. Microplitis strenuus Reinhard:
The only host from which this uncommon species has been obtained is
Diloba caeruleocephala L., and it was from this larva that the exhibit was
bred. The young host was taken at Salfords, Surrey, 29.v.1977; the strenuus
larva appeared early in June, and a 9 was bred 16.vi.77. Meteorus sp., nr.
fragilis Wesmael: Apparently an uncommon species. The @ exhibited was
bred 16.vi.1976 from a larva of Nola cucullatella beaten from Prunus
spinosa, 26.v.76, at Salfords, Surrey. Casinaria orbitalis Gravenhorst: A
2 bred 27.vi.1976 from a cocoon of Zygaena trifolii found 13.vi.76 at
Salfords, Surrey. When taken, the freshly spun cocoon still contained the
pre-pupal larva; shortly afterwards the host was killed. Casinaria moesta
Gravenhorst: From a cocoon of this species, found 13.11.1977 on Prunus sp..,
Salfords, Surrey, a specimen was bred 28.iii.77. The exhibitor had obtained
identical cocoons in this area from Campaea margaritata, but unfortunately
these had not been bred. Agrypon anxium Wesmael: A rather frequent
species, bred 18.x.1976, from an unidentified larva of the Tortricidae dis-
covered between birch leaves, 27.viii.76, on Studland Heath, Dorset.
Cratichneumon albifrons Stephens: From a lepidopterous pupa dug under

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 19

oak, 20.i.1974, near Reigate, Surrey; a @ of this rare (Perkins, 1959)
species appeared 20.1iii.74.

There then followed a collection of Ichneumonoidea caught in the field.
Zele testaceator Curtis: A Q caught at 6w. actinic light (hereafter ‘acl.’)
19.vii.1976, at Salfords. Zemiotes chrysophthalmus Nees: An example, ¢,
swept from low vegetation at High Halstow, Kent, 23.vii.77. Meteorus
scutellaris Nees: One of two (2) specimens which came to acl. 9.x.1976, in
Plaistow Woods, West Sussex. Banchus volutatorius Lin.: Two specimens,
2 &, illustrating the sexual dimorphism often encountered in this genus.
They were obtained 23.vii.1977 at Funton Kent, as they flew in the late
afternoon over low ground. Absyrtus ?vicinator Thunberg: A_ second
species of this genus may occur in Britain. The exhibited insect (2) was
obtained at myvl., 9.x.1976, in Plaistow Woods, W. Sussex. Enicospilus
tournieri Snellen: One of several examples which came to acl. in Dawlish
Warren, Devon, 14.viii.1977. Agrypon flaveolatum Gravenhorst: Perhaps
the most common of the sub-family Anomoloninae, the @ displayed was
secured on Brownsea Island, Dorset, 21.v.1977, as it flew in sunshine over
heathland. Aphanistes xanthopus Schrank: The exhibit showed a @ of this
rare species, which was swept from heather, 20.vi.1977, on moors near
Dawlish, Devon. Coelichneumon microstictus Gravenhorst: The specimen
(2) was captured in a shop window, 22.vi.1977, at Dawlish, Devon. The
species appears to be local and attached mainly to the S.W. coast. Cratich-
neumon corruscator Lin.: One example of the second generation, caught
31.vii.1976, in Plaistow Woods, W. Sussex. Although the males of this
generation are often marked with yellow, the exhibited male was so to an
excessive degree, even the propodum was entirely yellow.

The last four species consisted of common representatives of the
Ichneumoninae (in addition to the previous sp.). They were: Barichneumon
albilineatus Grav. (2), caught 24.ix.1977 at Reigate, Surrey; Jchneumon
sarcitorius Lin. (2), caught 3.vi.1977 at Reigate, Surrey; Ichneumon
deliratorius Lin. (@), caught at mvl. (unusually for this group), 9.x.1976,
in Plaistow Woods, W. Sussex; Amblyteles armatorius Forster (@), caught
3.vii.1977, in a cornfield, Reigate, Surrey.

SHaAw, M. R. — Interesting parasites, all of which were generously
donated by Lepidopterists, who thereby received acknowledgement of their
contribution to these studies. Litomastix sp. nr. truncatellus Dalman: An
exhibit of 100 examples of the above species (Chalcidoidea: Encyrtidae)
selected from a total of 1,914 males, all bred by K. Noble from a larva
of Apamea monoglypha Hufn. Macrocentrus grandii Goidanich: An all
female brood (total=54) of the species (Braconidae: Macrocentrinae) was
shown, complete with cocoon mass. The insects were bred by T. H. Ford
from a larva of Pleuroptera ruralis Scop. Both this and the sp. above
illustrate the phenomenon of the polyembryony; a mode of reproduction
in which a single ovum laid by the female divides many times in the host;
the resulting larvae necessarily produce adults of one sex only. Sympiesis
dolichogaster Ashmead: Examples, all 92°92, were shown bred from
Caloptilia leucapennella Stephens, collected by Lt.-Col. A. M. Emmet from
Quercus ilex at Tresco, Isles of Scilly, 1974, and from C. ?fribergensis
Fritzsche, collected by S. E. Whitebread from Acer pseudoplatanus at

ILLUSTRATIONS

This year the quality and variety of photographs and illustrations rose
once again, demonstrating the increasing swing towards these arts.

A series of the original illustrations from his forthcoming book The
Dragonflies of Great Britain and Ireland by Mr. C. O. HAMMOND were
the subject of much interest, as were illustrations for a butterfly and moth
stamp issue by Norfolk Island by Mr. B. HARGREAVES.

Amongst the photographs were a display by Mr. W. A. VicKERS of
prints from his complete collection of transparencies of the British butter-
flies, incuding the regular migrant species.

Messrs. P. A. SOKOLOFF and R. C. REVELS both showed prints of Rhopa-
locera aberrations. The latter also included black and white photographs
of the life histories of several butterflies. Mr. K. P. WitmMotr exhibited
photographs of some of the rarer butterflies (by invitation of Mr. G. Prior)
and Mr. R. W. J. UFFEN a number of subjects and natural history prints
demonstrating his prowess at all the photographic processes.

An interesting series of photographs showing inter-specific variation in
pupal characters of British Pyllonorycter (Lep., Gracillariidae) was the
subject of Mr. M. R. WiLson. These relate to the current construction of
a key to the pupal stage.

Lastly, a selection of colour prints of Lepidoptera by Mr. I. G. FARWELL,
which included pictures of the finding of an Acherontia atropos pupa and
following stages.

It is to be hoped that the excellent standard set will be maintained and
that the uses and scope of photography become more widely realised by
entomologists.

INSTAR NUMBER AND PUPAL COLOURATION IN
PALESTINIAN PIERIS BRASSICAE L.

by Brian O. C. GARDINER

(Agricultural Research Council, Unit of Invertebrate Chemistry and Physiology,
Department of Zoology, University of Cambridge, Downing Street, Cambridge,
CB2 3EJ)

ABSTRACT

Pieris brassicae L. larvae from Palestine have been reared at 15-20°C.
and 25-30°C. At both temperatures the number of larval instars was five.
This confirms recent statements by various workers and the early work of
Klein, still quoted in the textbooks, that the number of instars varies with
temperature is refuted and its basis queried. It is considered that brassicae
always has five instars. A note was made that the pupal colouration of
these Palestinian brassicae differed markedly from British examples.

In 1932, working in Palestine, Klein (1932) produced a paper in which
he claimed that the larvae of P. brassicae had a variable number of instars
according to the temperature of rearing. These varied from three at rearing
temperatures of over 25°C. to five at below 15°C. This report was shortly
picked up by Hoskins & Craig (1935) in their review of insect physiology
and has remained in the physiological literature ever since. However, the
taxonomic and biological literature has continued to state there are five
instars, without mention of variability (Frohawk, 1934; Howarth, 1973) and
no confirmation of Klein’s results has come to my attention. On the
contrary, all authors who have used brassicae as an experimental insect,
when rearing at temperatures which, according to Klein, should have
produced three or four instars, all state that they had five instars (Gibson
& Silvestre de Sacy, 1956; Long, 1955; Schoonhoven, 1967; Srihari, 1970).
In 1962 David & Gardiner published the results of very detailed work on
large numbers and maintained that the number of instars was constant at
five over the whole range of temperatures from 10-33°C. at which rearing
of the insect is possible. They made the proviso that Klein’s contrary
findings could perhaps be due to some physiological difference in brassicae
originating in Palestine. After many years over which tens of thousands
of larvae were bred, Gardiner (1974a) again reaffirmed the constancy of
five instars. In spite of all these findings, however, Klein’s results continue
to be quoted in the standard textbooks (Wigglesworth, 1972 for instance).

In 1977, due to the kindness of Miriam Rothschild, who brought some
brassicae eggs back with her from Palestine, I was able to rear Palestinian
brassicae under the same temperatures at which Klein stated they had three
and four larval instars.

The eggs arrived in two batches, laid on Nasturtium (Tropaeolum majus
L.) and Caper (Capparis spinosa L.) respectively. All those on the Caper
hatched, but only about 25% on the Nasturtium, to give a total of 96
larvae. Half these were reared at 15-20°C. and half at 25-30°C. under
normal British May daylight. According to Klein these should have had
four and three instars respectively. Not so. The larvae were fed on cabbage
and a control batch of the five instar ‘Cambridge’ brassicae (David &
Gardiner, 1962) run alongside for comparison. All the larvae passed through
five instars and 48 and 44 pupae respectively were obtained from the cool
and the warm conditions.

The chrysalids, however, were strikingly different from those of the
Cambridge stock. It has already been reported that the Cambridge chrysalids

22 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

are straw-coloured, or green when in diapause (Gardiner, 1974b). However,
this is not so during the first few hours after formation. As the larval
skin is shed all chrysalids are bright green with a bright yellow dorsal keel.
They then change to their final colour. The Palestinian brassicae chrysalids
on formation were a pale mauve colour and the dorsal keel was a very pale
straw colour. This mauve gradually faded to give the final colour. In these
non-diapause chrysalids this was silvery-grey, more nearly resembling in
colour that of a P. rapae as figured by Poulton (1887), Fig. 35, his plate 26.

The reason for this colour is not clear, but may be due to the necessity,
in Palestine, of being cryptically coloured and this silvery-grey colour is
one which can be associated with hot dry climatic conditions.

David & Gardiner (1962) and Gardiner (1974a) based their results on
literally tens of thousands of larvae. It is difficult to decide how many were
used by Klein. Certainly his observations appear to be based on far fewer
larvae than have just been reared from Palestine. He also suffered from
appalling mortality and it is quite possible that at that time (1928-30)
brassicae in Palestine were suffering from the outbreak of virus disease
first reported by Paillot in 1924. In his introduction Klein states that he
observed much material, but we find in his Table 8, a mere 17 records of
larvae and it is on this table that the entire statement that brassicae has
fewer instars at higher temperatures is based. It is worth quoting a transla-
tion of his account in full.

‘In the course of the year we have observed moulting of the larvae and
we noticed that the duration of instars was different in different seasons.
We set up breeding to investigate the number of moults in relation to
climatic factors and the larval duration. We now observed that for each
10-day duration of the larval period there is an additional instar. The least
number of moults can be seen at the highest temperature and lowest
humidity and this coincident with the shortest duration of the development
of the larvae.’

Nowhere do we find any account of how he followed the instars. There is
no mention of measuring of head capsule size, as was done by David &
Gardiner (1962). If we turn to Klein’s Table 9 we find a sixth instar listed,
which is not only unaccounted for by explanation in the text, but is in
conflict with Table 9 as at the temperature 14.6-15°C. Table 9 lists six
instars, but Table 8 only five.

The very high larval mortality observed by Klein is given in his Tables
20, 21 and 22. These are so incredibly high that in my opinion they are
most likely to have been due to virus disease. It is also of interest that
Table 22 again lists six instars. Additionally the 100% mortality in the first
two instars at temperatures exceeding 25.3°C. must in themselves leave
suspect that only three instars occur at these temperatures.

Having now had the opportunity of rearing Palestinian brassicae, even
though in small numbers, I feel that David & Gardiner’s (1962) statement
that the larval instars are constant at five is reinforced and the statement
in the textbooks that the instars decrease with temperature, needs to be
expunged from future editions.

I would like to thank Miriam Rothschild for bringing me the eggs from
Palestine, and Dr. H. J. Pfliiger for the translating of Klein’s paper.

A REVISION OF THE BRITISH ASTEIIDAE (DIPTERA)
INCLUDING TWO ADDITIONS TO THE BRITISH LIST
by PETER J. CHANDLER

(Weston Research Laboratories, 644 Bath Road, Taplow, Maidenhead, Berks.)

The Asteltidae are a small family of about a hundred known species,
arranged in ten genera, although nearly half belong to Asteia itself. Three
genera including seven species may now be recognised as British; the
discovery of Astiosoma rufifrons Duda under unusual circumstances has
led me to pursue the problem of the identity of our species of Leiomyza
which have hitherto been confused, although they were dealt with by
Sabrosky (1956a) in the European context.

They are small flies, which were formerly included among the Droso-
philidae although recent taxonomic researches (Hennig, 1965; Griffiths,
1972) have suggested that they are closer to the Anthomyzidae, Trixosceli-
dae and Opomyzidae. They differ from all these groups in the unbroken
costa. The wing venation is characteristic. the second basal cell being
confluent with the discal cell (if present) and the anal cell absent (at least
in British genera), while the subcostal vein is only visible basally and
veins 3 and 4 are convergent apically. The legs are simple in both sexes
and vibrissae are usually absent or weak (although quite well developed
in our species of Asreia itself). Most species are brightly marked in black
and yellow, although Leiomyza have uniformly dark bodies.

Leiomyza is different in several respects from other members of the
family, both in its association with fungi and structurally. Griffiths (1972)
has mentioned the presence of double telomeres as had already been

24 PROC. BRIT. ENT. NAT. HIST. soc., 1978

depicted by Sabrosky, who included the genus in his sub-family Sigaloessinae
with Astiosoma on the basis of the wing characters. Hennig (1969), when
dealing with his fossil genus Succinasteia, concluded that Leiomyza had a
sister group relationship with all other Asteiidae but otherwise recognised
the remaining Sigaloessinae as a ‘Phlebosotera-group’, the Asteiinae being
retained as his ‘Asteia-group’. Sabrosky (1977), however, discussed the
genus Anarista (Papp, 1972) indicating that it cut across this sub-division
in possessing a posterior cross-vein but lacking an alula. In any case, the
genital structure confirms that Astiosoma is more closely related to Asteia
than to Leiomyza. The telomeres in Astiosoma show slight asymmetry
tending towards that found in Asteia, while they are completely symmetrical
in Leiomyza.

— Hind cross-vein present opposite end of second vein; alula present,
margined with long hairs. Orbitals short and weak. Arista with
very short pubescence. No distinct vibrissae ............ Astiosoma Duda

There is only one other European genus, Phlebosotera Duda (two species

in Greece and Cyprus), which agrees with Astiosoma in the venational
characters except in the presence of a faint but clearly traceable anal
vein and short quadrate anal cell; it agrees with Leiomyza in possessing
mesopleural hairs.

Genus Astiosoma Duda

This is a small genus with only eight described species (Sabrosky, 1956a;
1957) of which half are Nearctic, two Oriental and one Australian. In
Europe it is previously known only from the single Yugoslavian female
described as A. rufifrons by Duda (1927). According to Sabrosky, the Old
World species are all very similar, his okinawae also described from a
single female being particularly similar to rufifrons. The British material
described here agrees essentially with Duda’s description and figure of the
wing venation; the type (which was in the Budapest Museum) is presumably
lost and in the absence of other European material the British specimens
are considered conspecific with rufifrons.

Astiosoma rufifrons Duda (Figs. 1-3)

A. rufifrons was localised to one small area of the forest, where both
sexes were equally attracted to cold wood ash spread out over the ground
after bonfires. On 27.vi and 4.vii it was very numerous but could not
be found elsewhere in the vicinity, although most flies were exuding a
sticky material from their proboscis and it was concluded that they had
been feeding at pine sap. It may be significant that my visits were during
the evening from 7.0 p.m. to 8.30 p.m. On 24.vii only two examples
could be found so it was assumed that the main peak of its flight period
had passed; the male taken on this occasion was swept over damp
fermenting wood chippings about one metre from the nearest area of ash.
Then on 11.ix at Old Windsor Wood, A. rufifrons was found again about
several still smouldering bonfires of elm branches, etc.

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 29

Nothing has been recorded previously of the habits of Astiosoma; the
occurrence of some species on saw-mill windows in North America may
have been fortuitous. The reason for the attraction to wood ash remains
obscure but it is remarkable that such a distinctive (although small) fly
which has not been collected in the British Isles before, should be found
assembling in such large numbers in a circumscribed area while it could not
be found by intensive collecting in the immediate surroundings. The
discovery of Astiosoma as a British insect was a result of the previous find
of the Empid ‘Smoke Fly’, Hormopeza obliterata Zett. (only the second
British record) when the bonfires concerned were still smouldering. Hormo-
peza and other insects found during several visits to the site are discussed
elsewhere (Chandler, in press).

Genus Asteia Meigen

Asteia is better developed in the Mediterranean region than in northern
Europe, where only three of the nine described Palaearctic species (Duda,
1934; Sabrosky, 1956a; Lyneborg, 1969) occur, these three being found in
Britain.

Sabrosky (1956a) commented that Mr. J. E. Collin was investigating
a new species of Asteia near elegantula. Dr. C. W. Sabrosky kindly
forwarded to me copies of his correspondence with Mr. Collin about this
matter during 1955. Sabrosky had examined a British example of elegantula,
which he found to differ from other European material (including Zetter-
stedt’s type) in several respects. The latter had a mainly yellow occiput
and a narrow black band near the upper margin of the sternopleura.
Through the kindness of Dr. H. Andersson, I have been able to study
the holotype male of Asteia elegantula Zetterstedt (Sweden: V£Astergot-
land) and compare it with British specimens.

The holotype is smaller than the British material (having wing length
2.8 mm.) but the sternopleural band, which is darker brown than the
other dark thoracic markings, is the only significant difference that I can
detect. Although there is no vestige of this band in the British examples
seen, preparation of the male genitalia of the two forms failed to reveal
any characters obviously of specific importance. Examination of a larger
amount of material from throughout its range, would be necessary to
establish the precise status of the British and continental forms of A.
elegantula.

was taken on a river bank but its other localities suggest at least a
preference for wooded habitats.

Asteia amoena Meigen (Fig. 5)

Generally common in woods, 29.iii-28.x, and known to hibernate as an
adult; it is frequently found amongst the branches of various trees,
including yew and conifers, or sheltering among the foliage of shrubs such
as Buxus or Cupressus. | have found it feeding at ivy flowers (Hedera) and
it might also feed at sap exudations. It has been recorded as developing
in wood detritus but the open habitats of A. concinna suggest that this
cannot be a habit common to all species of A steia.

Material has been seen from Kent, Surrey, Sussex, Hants., Isle of Wight, -
Berks., Bucks., Oxon., London, Herts., Essex, Suffolk, Norfolk, Cambs.,
Cornwall, Somerset, Hereford, Powys, Glamorgan, Lancs., Cumbria, Moray
(Nairn, Falls of Tarnash, Glen of Drumloch), Wicklow, Dublin, Louth,

of its range. It occurs throughout Europe and also in the Canary Islands
where I have found it commonly in the laurel and chestnut woods.

Local, chiefly in marsh (including saltmarsh), fen, dune slacks and other

Genus Leiomyza Macquart

I previously discussed (1973) variation in British material of this genus
which I had found in association with fungi. Unfortunately, I was then
unaware of the work of Sabrosky (1956a and b, 1957) on the World
Asteiidae in which he clarified the nomenclature in this genus.

Formerly, all specimens with dark halteres were referred to laevigata
(Meigen) but Sabrosky (op. cit.) established that there were three species
with this character, two of them European, and I have found that both
occur in Britain; L. dudai Sabrosky is here introduced as new to the
British list.

On the other hand, several names have been applied to Leiomyza with
pale halteres, among which scatophagina (Fallén) has priority. Kloet &
Hincks (1945) listed only laevigata and scatophagina as British species,
with flavipes (Fallén) and glabricula (Meigen) as synonyms of the latter.
In the revised edition of the British Check List (1975), glabricula is
elevated to specific rank but this is evidently in error, Sabrosky (1956a)
having placed it in synonymy with scatophagina, thus following earlier
authors in this assessment. He recognised a second Holarctic species with
yellow halteres, i.e. curvinervis (Zetterstedt) (=opacifrons Duda), dis-
tinguished by a duller frons and its dorsocentrals being arranged as in
laevigata as well as small genital differences.

I have reared all of the three British species I can recognise from
lignicolous gill fungi; visiting records include a soft Polypore and a
terrestrial gill fungus. Sabrosky (1957) noted this habit in North America
and it may be common to all members of the genus, although unknown
elsewhere in the family. The published reference to the rearing of L.
scatophagina from reeds attacked by Lipara (Séguy, 1934; Colyer &
Hammond, 1951) is therefore considered unlikely and may have resulted
from confusion with one of the smaller Anthomyzidae or Chloropidae.

Leiomyza are all very similar, shining dark brown to black flies of wing
length 2-3 mm., with the face and jowls brownish yellow, anterior margin
of frons, palpi and antennae yellow except dorsal and apical darkening
of the third antennal segment, and the legs pale yellow except for the
darkened apical tarsal segment of each leg. There is a sexual difference in
the relative lengths of the fore tarsal segments in scatophagina where the
male has the metatarsus distinctly shorter than the combined length of
the remaining segments (as in both sexes of the other species) while the
female has it about equal to the remaining segments. All materia! of
scatophagina and many older specimens of the other species I have
examined have the ground colour of the frons brownish yellow in contrast
both to the black orbits and to the pale yellow fore margin; Sabrosky
stated that it was generally blackish in all species except curvinervis but

the frons is always distinctly shining in the British species which should
enable recognition of curvinervis if it were subsequently found here.

Leiomyza scatophagina (Fallén) (Fig. 7)

Probably common throughout the British Isles, 12.v-15.x. All pale
haltered British material has been found to belong here and this includes
those I recorded (1973) in association with Volvariella, Oudemansiella
and reared from Armillaria; 1 have also taken examples on rotten Polyporus
squamosus and on Coprinus radians.

L. scatophagina has been seen from Kent, London (N.W. Kent), Sussex,
Hants., Berks., Bucks., Oxon., Wilts., Gloucs., Devon, Hereford, Cambs.,
Suffolk, Powys (Cathedine Common), Moray (Logie, Brodie), Inverness
(Aviemore), Tipperary (Woodrooff Woods, 22.vi.75, P. J. Chandler) and
Mayo (Westport Demesne, 29.ix.77, P. J. Chandler) (there are two Irish
females in Haliday’s collection, probably from Co. Down).

Leiomyza dudai Sabrosky (Fig. 8)

Only seen from south-east England but apparently common. there;
16.vi-14.ix; the dark haltered material I recorded (1973) from Volvariella,
Oudemansiella, Tricholoma and Hypholoma belong here as do those reared
with scatophagina from Armillaria. Males from all these fungal associations
have been dissected and found to be conspecific and it is concluded that all
species of Leiomyza are probably polyphagous. The material reared by
Buxton (1960) from Pleurotus included both dudai and laevigata, the
former predominating.

L. dudai has been seen from London (N.W. Kent), Surrey, Sussex,
Hants., Berks., Bucks., Hereford, Cambs., Suffolk and Norfolk.

Leiomyza laevigata (Meigen) (Fig. 9)

This too is probably common throughout the British Isles, although
again most records are from the south; dates range from 26.v-17.ix. The
material I recorded (1973) rearing from Pleurotus cornucopiae were
laevigata and Buxton’s 1952 rearing from this fungus was also /aevigata.
Many were found about fungi on elms in his garden by Jenkinson but it
appears probable that it will be found to attack other fungi.

L. laevigata has been seen from Kent, London, Surrey, Sussex, Hants.,
Berks., Bucks., Cambs., Norfolk, Suffolk, Hereford and Moray (Nairn,
Brodie); a single female, labelled ‘Ireland’ in Haliday’s collection (National
Museum, Dublin), has been confirmed as /aevigata.

OBITUARIES
DENZIL WALTER HUGH FFENNELL

On 16th August, 1977, Denzil Ffennell died suddenly while attending his
moth traps in his grounds at Martyr Worthy, Hampshire, at the early age
of 56. The son of a banker, Denzil spent his life in his beloved Hampshire
apart from schooldays at St. Peters Court, Broadstairs, and Eton College,
a year at Cambridge before the war, and wartime service with the Hamp-
shire Carabiniers Yeomanry and Hampshire Regiment which took him to
North Africa and Italy, where he served with distinction in the rank of
captain. He was wounded, and during his convalescence he caught four
Bath Whites on the sea front at Ramsgate armed, appropriately enough,
with nothing more than a bath towel! That was in 1945, and after
returning for a few more months service in Germany, he was able to
settle down at Martyr Worthy. There he ran a successful market garden
which claimed his undivided attention in the early months of the year,
but left him fairly free after that to follow the pursuits of a country
gentleman: he was an excellent shot, a keen and skilful dry fly fisherman
on the nearby Itchen, a knowledgeable field botanist and, above all, a
first class lepidopterist with a rapidly expanding knowledge of the smaller
Lepidoptera, which made him pre-eminent in Hampshire and one of the
leading microlepidopterists in the country.

Denzil’s is a collector’s collection. He was not particularly interested ©
in local races of insects and seldom took more than half-a-dozen specimens

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 35

of a species; to him, entomology was a contest with Nature and, one
suspects, with his fellow bug-hunters—every species added was a point
scored, and he enjoyed a pleasant game of one-upmanship with his friends
whenever he got a special rarity. The writer once received a postcard,
written in green ink (!), announcing the capture of Daphnis nerii (Linn.)
in the garden, with the comment that ‘he was pleased to get it, as it was
the commonest migrant he had not yet taken’. That same garden, in which
native species abounded, also yielded in its time such rare migrants as
Euchromius ocellea (Haw.), Diasemiopsis ramburialis (Dup.), Cyclophora
puppillaria (Hiibn.), Hippotion celerio (Linn.), Eurois occulta (Linn.),
Mythimna unipuncta (Haw.), no less than three Tathorhynchus exsiccata
(Led.), two Eublemma ostrina (Hiibn.) five E. parva (Hiibn.), a couple of
Trichoplusia ni (Hubn.) and Catocala fraxini (Linn.). This last was also
the subject of a ‘typical’ Denzil story: he opened the trap and there was
this large Catocala with a few C. nupta (Linn.); lifting a forewing with
forceps, he noted the mauve hindwings and said to himself, ‘Ah, fraxini’,
and sauntered back to the house for a larger pillbox. The moth was still
there when he got back so, after another look at the hindwings, he duly
boxed it! My nupta always fly off if I so much as glance at them. Most
of the native species had fallen to Denzil’s wiles, and he had visited most
parts of the British Isles, doing good work in Shetland, parts of Ireland,
the Scilly Isles and elsewhere. He was prevented from reaching the early
spring Scottish species and had a few bétes noires, the most notable of
which was perhaps Harpyia bicuspis (Bork.), which evaded him to the last.
Denzil was also interested in the Trichoptera, and had a good representative
collection.

Denzil’s greatest interest was in the Lepidoptera of his own county, and
as his knowledge of the micros grew, he added species after species to
the county list, and two, Phyllonorycter dubitella (H.-S.) and Lampronia
flavimitrella (Hibn.), which were new to Britain. ‘The Butterflies and
Moths of Hampshire and the Isle of Wight’ is a monument to Denzil’s
energy. It was Denzil who persuaded the author to begin writing, Denzil
who found support and financial backing, and Denzil himself who provided
so many records — nearly fifty new county records and innumerable new
records for each of the three vice-counties. It is understood that more
records have come from Denzil’s own grid square than from any other
10 km. square in the whole of Britain.

Denzil wrote beautifully—even his postcards were masterpieces of
elegance — and his contributions to the entomological journals were always
most readable. He wrote several attractive articles for The Field and
Country Life which could have been used with great advantage in the
English classroom. Occasionally he wrote to amuse rather than to instruct,
always applying the same high standard of craftsmanship. All those who
had the privilege of knowing Denzil will testify to his good nature and sense
of fun. Not only did he enjoy life, he was seen to be enjoying it: a happy
man, a kindly, generous man, a mine of information on country lore
which he took pleasure in expounding, a lover of the countryside, a
raconteur abrim with amusing tales of insects, places and people, yet totally
devoid of smut or malice which are sometimes thought to be essential
ingredients of a ‘funny’ story. Denzil was a man folk will wish to remember.
To Jane, his wife, and to Simon and Diana, we offer our sincere condolences
and share their untimely bereavement.

AN OBITUARY AND BIBLIOGRAPHY OF
HENRY CHARLES HUGGINS, F.R.E.S.'
by J. M. CHALMERS-HUNT
(St. Teresa, Hardcourts Close, West Wickham, Kent, BR4 9LG)

Henry Charles Huggins died on the 14th April, 1977, clinically from
pneumonia following a relapse after an operation for prostatitis, though
the real reason for his giving up was the realisation that he would lose
his independence and never again be able to collect. He was born at
Gravesend on the 17th May, 1891, the elder son of Henry Huggins, J.P.,
who was also an entomologist and contributed to some of the early volumes
of The Entomologist’s Record.

Very early in life H. C. Huggins showed a keen interest in natural
history and especially the British lepidoptera, of which he started to form
a collection at the age of eight and continued to add to it throughout his
lifetime. He was fortunate in having as his chief mentors the Rev. C. R. N.
Burrows (of whom he wrote an appreciation in 1954) and the renowned
microlepidopterist Benjamin A. Bower. He was also helped in his youth
by A. B. Farn (a second cousin of his grandmother, Mrs. Louisa Huggins
née Farn).

For the first forty years or so much of his collecting was done in his
native Kent, and he was probably the only man still surviving to have
taken there the Marsh Fritillary (Euphydryas aurinia Rott.) and the Black-
veined White (Aporia crataegi L.), the former at Ham Ponds in 1905,
and the latter at Eastry in 1906.

For a while he collected British and Irish land and freshwater mollusca,
publishing a paper on the Irish Limnaeae in 1918, in which he suppressed
two so-called species, L. involuta Thomp. and L. praetenuis Bowell. How-
ever, his chief interest lay in the lepidoptera, particularly those of Ireland,
to which country he undertook 36 visits, the first about 1913, and the last
in 1973 in the company of the writer. Among a number of new Irish
subspecies that he described were Erynnis tages baynesi, Gonopteryx
rhamni gravesi, Eupithecia vulgata clarensis and E. venosata plumbea.

After 1922, Huggins concentrated on micros of which he was later to
become one of the leading authorities in this country. Although a prolific
writer on the subject of lepidoptera, it seems it was not until 1923 that
his first entomological contribution appeared in print. He was then already
32, but during the next fifty years his output was to exceed 400 published
communications. Many of these are of considerable interest, particularly
his series ‘Notes on the Microlepidoptera’ which appeared at intervals from
1951-74.

He joined the (then) South London Entomological and Natural History
Society in 1934, reading in 1956 a paper on the Burren, and in 1959 one
on Kerry, both of which were published (see bibliography).

Harry Huggins was a most interesting companion and entertaining
raconteur with a fund of anecdote, much of it entomological reaching back
to the beginning of the century. He was also an excellent correspondent
and his letters no less than his published writings never failed to give
enjoyment.

His fine collection of lepidoptera down to the Tortricoidea (he did not
collect Tineoidea) as well as his British and Irish land and freshwater
mollusca have been presented to the British Museum (Nat. Hist.).

To his only son, who like his father became manager of a branch of
Westminster Bank, we offer our sincere sympathy.

Rec., 89:223-224.

28th July 1977

The President. Mr. R. S. Tusss, in the chair.
EXHIBITS

Rey. D. J. L. Acassiz. — Parapoynx diminutalis (Snellen), Nymphula
linealis Moore, and an apparently unnamed Nymphula sp. (Lep., Pyralidae)
all three introduced species from the Far East found breeding at Enfield,
Middlesex.

Dr. A. A. ALLEN. — (i) A female of Aphanistes xanthopus Schrank
(Hym., Ichneumonidae) which was obtained by sweeping moorland heather,
20.vi.1977, near Dawlish, Devon. The species is considered to be rare and
is parasitic on noctuid larvae and possibly other families of Lepidoptera.
The Anomalinae, to which sub-family A. xanthopus belongs, are solitary

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 39

endoparasites of lepidopterous larvae; the young larva is attacked, but the
adult Anomaline always emerges from the host pupa. The group parasitises
a very wide range of families, including ‘Microlepidoptera’. (ii) A short
series of Clyphipteryx linneella (Clerck) (Lep., Momphidae) found as adults
on trunks of Tilia sp. (lime), 25-26.vi.1977, at Manor Park, London, E.12.
Meyrick (1927) states that the species is ‘very local, but common where
it occurs’; certainly a number of imagines were observed flying around
the trees in the midday sunshine. The larva feeds on the bark of Tilia.
(iii) A specimen of Stathmopoda pedeilla (Linn.) (Lep., Stathmopodidae)
disturbed from a well-established grove of Alnus glutinosa (alder) on
Brownsea I., Dorset, 9.vii.1977. The moth is local and seems very uncom-
mon; the larva feeds in the fruits of alder.

B. R. Baker. — Ova of Bembecia scopigera (Scop.) (six-belted clear-
wing). The larval habit of this species of tunnelling the roots of Lotus
corniculatus is well known but details of the precise oviposition site appears
to be missing from the literature; an investigation was therefore carried
out on 19th July, 1977. Two males and two females were swept from a
richly flowered chalk slope and these were subsequently placed in a large
glass tank in which was planted some small clumps of Lotus corniculatus,
Bird’s Foot Trefoil, and associated small plants; the tank was situated
outside in the garden. Under dull conditions the moths were entirely
inactive but in bright sunlight on the afternoon of 20th July all four
specimens flew vigorously and the females oviposited between 3 and 4 p.m.
Eggs were laid on the leaves of Lotus and occasionally on the stems and
exposed roots; a few were laid on leaves of other plants such as Poterium
sanguisorba, Salad Burnet. One of the males died after three days, the
remaining three specimens lived for 5 days. The eggs are black, with faint
whitish reticulations (only discernible under high power), in shape they are
ovoid discs with longest axis 0.57 mm.; broadest 0.36 mm. and 0.27 mm.
depth. As a control to check whether leaves were a natural oviposition site,
a return was made to the chalk slope on 27th July and a total of five eggs
were found; two of these were on leaves of Lotus, two on Polygala and
One on an undetermined leaf, but all within easy access of abundant
Lotus.

A. M. Emmer. — A living imago, cocoons, and vacated mines of
Stigmella aceris (Frey) from a locality near Edenbridge, Kent. The food-
plant is Norway Maple (Acer platanoides). The first British specimen was
bred by Lord Walsingham in 1914/15 and is unset, on a card, in the
British Museum (N.H.). The second emerged earlier the same day as the
example exhibited. Vacated mines had been found in Kent by S. N. A.
Jacobs and S. A. Whitebread.

G. Prior. — (i) Larvae of Eupithecia pulchellata Steph. f. hebudium
Sheldon, from the N.W. coast of Argyle, received from Dr. Edwards. The
larvae are rather darker than the southern British form and when about
to pupate become almost black. (ii) Larvae of E. lariciata (Freyer) from
larch, Watlington Hill, Oxfordshire. (iii) A handsome but undetermined
moth taken in Westminster Cathedral.

MATTERS ARISING FROM THE PREVIOUS MINUTES

S. N. Jacoss remarked that he wondered if the explosions at Denny
Bog were connected with reported discoveries of dead New Forest ponies
with broken limbs far from the roads.

MEMBERSHIP

The obligation book was signed by Miss Marrable, and Messrs. P. M.
de Souza and D. C. Lees.

COMMUNICATIONS

R. F. BRreETHERTON stated that Heterographis oblitella (Zeller) (Lep.,
Pyralidae) which had such a population explosion in Southern England fast
year, had reappeared this year at his light trap at Bramley, an inland
locality, and was presumably breeding there. D. AGassiz said that its
usual foodplant was Chenopodium, which was most persistent on salt
marshes. Its captures had previously mainly been on such habitats, giving
rise to the idea that they were immigrants from overseas.

R. Dyke reported having taken Mythimna vitellina (Hiibner) on 13th-14th
July, 1977 in Devon. R. F. BRETHERTON observed that this species was
normally unable to overwinter in Britain and the examples were therefore
most probably immigrants.

Dr. S. A. Knitt-JoNes reported the capture of Gonepteryx rhamni
(Linn.), a small female, in Shaftesbury Avenue, London.

C. Hart reported that on 16th July, 1977 a male Cossus cossus (Linn.)
had been taken at light at Sandwich.

M. W. F. Tweepie then gave a talk briefly describing his methods of
photographing butterflies and moths, and then showed excellent slides of
these taken in Britain, Spain, St. Vincent, W.I., Turkey, Malaysia and
Sumatra. The audience showed its appreciation of these in the usual

OBSERVATIONS ON EXHIBITS

Dr. J. D. Brapiey said that Mr. Prior’s third exhibit was probably a
South African Oecophorid moth of the genus Cryptolechia Zeller.

8th September 1977

The President, Mr. R. S. Tupss, in the chair.

The President announced with regret the deaths of (i) Professor H. E.
Hinton, aged 64, who was Head of the Zoology Department, Bristol
University, where he had worked since 1949, President of the Royal
Entomological Society 1969-70, and President of our Society for its
Centenary Year; and (ii) Denzil W. H. ffennell, well known to most
members as a lepidopterist, particularly a micro-lepidopterist; he died
suddenly in the middle fifties while attending his moth trap near
Winchester.

EXHIBITS

Rev. D. J. L. AGassiz. — A seies of Oligostigma angulipennis Hampson
(Lep., Pyralidae), new to Britain, from aquatic nurseries at Enfield, Middx.

Dr. A. A. ALLEN. — (i) Two parasitic species (Hym., Ichneumonidae),
one primary, one secondary (true hyperparasite) of Quercusia quercus (L.)
(Lep., Lycaenidae). The primary parasite was an unnameable species of
the genus Phobocampa, the members of which are parasites of immature
larvae of Lepidoptera. No keys exist for the majority of the Phobocampa,
a problem which is also presented by the large genus Mesochorus to which
the secondary parasite belongs. In an attempt to obtain the Phobocampa
species, eleven young larvae of Q. quercus were collected by beating from
oaks, 28.v.1977, in Vert Wood, East Hoathly, Sussex. Although nine of
these were healthy and soon attained full size, two larvae remained rather
small, an indication of parasitism. By early evening of 1.vi one larva had

PROC. BRIT. ENT. NAT. HIST. SoOc., 1978 41

become motionless, and became paler brown than its companions. During
the evening it became almost colourless and transparent and the parasite
maggot could be seen moving inside the host’s skin. By 5 a.m. the following
morning (2.vi) the parasite larva had appeared and spun its cocoon near
to the empty skin of the host. The second affected larva underwent the
same sequence of events, the parasite larva appearing and constructing
its cocoon on 4.vi. The cocoons were dark purplish fuscous; had the
humidity of the environment been lower they would probably have been
lighter, approximately whitish-grey with blackish blotches. From the first-
spun cocoon a female Phobocampa species hatched on 22.vi while the other
cocoon gave rise on 26.vi to a male Mesochorus species, the primary
parasite of this Phobocampa and in turn a secondary parasite of Q. quercus.
The Phobocampa sp. has also been recorded from Thecla betulae (L.)
(brown hairstreak) and appears to be a rare insect, perhaps only to be
found in the south of England. Larvae collected at Salfords, Surrey, in late
May, failed to give the parasite. (ii) A 2 of Paracystola acroxantha Meyr.
(Lep., Oecophoridae) captured in an actinic light trap during the night
of 17-18.viii.77 outside the first floor of a guest-house at Dawlish, Devon.
The moth was in fresh condition and was kept alive, mainly in the dark
at room temperature, and during the night of 19-20.vili three ova were
obtained, the moth unfortunately dying in the process. When laid, the
Ova were translucent and almost colourless, with a delicate pale yellow
tinge. In shape they were oval (as opposed to elliptical), and slightly flattened
top and bottom. They remained in this state until 31.viii when they
became slightly darker and two larvae hatched during the night of 1-2.ix;
an ovum was lost. The larvae, after hatching, were 2 mm. in length, and
white with a shining mid-brown head. The body, clothed in some short
fine, almost colourless hair, carried the usual number of legs; claw-legs
on segments 2, 3 and 4, and pro-legs on ss. 7, 8, 9, 10 and 14 (adopting
Meyrick’s convention, with the head counted as the first segment). The
larvae were very lively. The inevitable problem was the choice ‘of food
on which to rear the species, for no foodplant had, to the exhibitor’s
knowledge, been recorded for P. acroxantha; unfortunately this problem
remains insoluble. As soon as the larvae had hatched, samples of the
following were introduced to the receptable: elm, apple, bramble, dandelion,
ivy, gooseberry, strawberry (cultivated), thyme, box, and heather. Eight
hours later the larvae were still wandering restlessly, so further food, yew,
privet, holly and birch leaves, were offered and finally a bay leaf was
supplied. Unfortunately the larvae found none of these attractive, but
possibly they nibbled a holly leaf. In any event, the larvae were not seen
again and it must be assumed they died of starvation. There is a theory
that they feed on eucalyptus. The ova were stored in a cool place, so
presumably in the field they hatch before winter as in captivity. Kloet &
Hincks (1972) gives the status of P. acroxantha in Britain as uncertain.
The present capture constitutes only the seventh authentic record of the
moth in Britain (although a fore-wing may be counted as an additional
half-record), the years of capture being 1908, 1917, 1925, 1970 and 1976,
all in the South Devon area between Torquay and Ottery St. Mary. The
usual month given for the flight season is August (Meyrick, 1927 and
Jacobs, 1949-50, in Proc. South Lond. ent. nat. Hist. Soc., p. 189)
but the two specimens caught in 1976 by the present exhibitor were both
in June. Although the summer of 1976 was very hot, the high temperatures
had only just begun by late June, and it is possible that instead of a
premature appearance being the explanation of the 1976 dates, the insect

42 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

may be bivoltine. Slight further evidence is supplied by a consideration
of the wing-span of the species, given by the above authors as 13-15 mm.
The female captured in 1977 measured 13 mm. across, but the 1976 female
spanned 18 mm.; often first broods are of a larger size. The exhibitor
had visited the area in June 1977 in an attempt to secure P. acroxantha
but was unable to find it, either in Dawlish nor the not-too-distant moors
which were the locality of the 1976 discovery. The exhibitor gratefully
acknowledged the kindness of the proprietress of the guest-house at whose
suggestion the light was run on a flat part of the roof outside his room.
His earlier capture was referred to also in Proc. and Trans. Brit. Nat. and
nat. Hist. Soc., 9, 117 (1976) and the species, as exhibited in last year’s
annual exhibition, was illustrated in Plate [IX of Vol. 10.

E. S. BrapForp. — Four species of rather local microlepidoptera: (i)
Cydia molesta (Busck) (Tortricidae): originally found in China and Japan
but now found in many parts of the world. The larva bores into the shoots
and fruit of peach and other fruit trees. It is usually imported into this
country in fruit; this example was found flying in a house in Kent having
probably emerged from some fruit on a bowl on the table in the living
room and pupated somewhere in the house; the exhibitor had himself
bred his first example of this species from a larva found in an imported
peach. (ii) Cydia conicolana (Heylaerts), an example which had emerged
from one of several cones of Pinus sylvestris picked up at Covert Wood,
near Barham, Kent, first noted in this country in 1930 in the New Forest
(by H. C. Huggins). (ili) Scythris grandipennis (Haw.) (Scythrididae) larvae
were found rather sparingly in spun shoots of Ulex in Clowes Wood,
Blean, Kent. (iv) Nemapogon albipunctella (Haw.) (Tineidae); a fresher
specimen than the one previously exhibited; the larva is said to feed on
decayed sticks.

G. R. Ese. — Local and mostly uncommon aculeate Hymenoptera
recorded from Leckford Estate, Stockbridge, Hants.: (i) Riparian species
(riverbank, poplar plantation and carr vegetation adjacent to the Test).
Anoplius caviventris Aurivillius (=piliventris (Morawitz); cardui Perkins).
1 @, 1 9, 12.vii.1977, G. R. Else. An uncommon spider-hunting wasp at
present recorded from only three Hampshire sites. Females nest in dead
stems and wood. Symmorphus mutinensis (Baldini) (=sinuatissimus
Richards). 2 2 2, 12.vii.1977, G. R. Else. A common wasp, usually charac-
teristic of damp habitats. Some Leckford females have been disvovered
nesting in the old reed thatch of riverside huts. Crossocerus walkeri
(Shuckard). 1 @, 10.vii and 1 @, 30.vii.1977, G. R. Else. One of the
specialties of the river bank, the wasp is rarely found more than a few
yards from the water’s edge. Nests in dead wood and provisions its cells
with Ephemeroptera (mostly Baetidae), rarely Diptera. Nationally a rare
species, but widely distributed. Hylaeus pectoralis Forster. 1 2, 30.vii.1977,
G. R. Else. Until recently this bee was known in Britain only from the
East Anglian fens and from an old (1901) specimen collected in the New
Forest. Since 1972 it has been recorded from about 13 Hampshire localities,
from Dorset, West Sussex and the Isle of Wight. Females are known to
nest only in the vacated galls of Lipara lucens (Meigen) (Diptera, Chloro-
pidae) on the apices of reed stems. Common in most Hampshire localities
but only a pair have been recorded from Leckford. Macropis europaea
Warncke (=/Jabiata auctt. nec (F.)). Only one female has been recorded
from Leckford, but the bee is no doubt established there. A local wetland
species which provisions its subterranean nest with Lysimachia vulgaris L.
pollen and nectar. The 2 specimen exhibited was collected at Browndown

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 43

(fen), near Lee-on-Solent, Hants., 26.vii.1972, G. R. Else. (ii) Chalk down-
land species. Andrena marginata F. One record only from Leckford,
probably a stray from an undiscovered colony on nearby downland. Visits
scabious flowers. The example exhibited was collected at Martin Down,
Hants., 28.vii.1976, G. R. Else. Melitta tricincta Kirby. 2 8, 20.vii.1977,
G. R. Else. A local bee with a preference for the flowers of Red Bartsia,
Odontites verna (Bell.). Gii) Nationally declining species. Andrena rosae
Panzer. 1 4, 13.iv.1947, D. McCarthy. Bombus ruderatus (F.). 1 2 (melanic
form — endemic in Britain), 28.iv.1947, D. McCarthy.

Lt. Col. A. M. Emmet. — (i) (on behalf of R. J. REVELL) a specimen
of Eucosma metzneriana (Tr.) (Lep., Totricidae), captured at light in a
chalk-pit on the Gog-Magog Hills, near Cambridge, on 22.vii.77. The
species is new to Britain, but is known to occur in France and Belgium
and to range eastwards to Japan. The larva feeds in the terminal shoots
of wormwood (Artemisia absinthium) and mugwort (A. vulgaris) from
August until May. (ii) on behalf of I. Stms an example of an exotic
Noctuid moth later determined as Agrotis deprivata (Walker), bred from
a larva found in a warehouse in England.

S. A. WiLLtiams. — Coleoptera from the Leckford Estate, taken
27.vi1.1976: Amarochara umbrosa (Erichson) and Borboropora kraatzi Fuss.,
both in grass cuttings; Gnathoncus schmidti Reitter, in tawny owl nest;
Epuraea distincta (Grimmer), in fungus; and Leptura fulva DeGee, on
flowers.

COMMUNICATIONS

The President reported that he had captured one Ladoga camilla (L.) f.
nigrina in a wood near Winchester and failed to obtain ova from females
flying at the same spot, but later found ova there which he hoped to rear,
but it would be two years before he could hope to obtain from them the
same form.

C. G. DE Worms stated that this year had been rather thin for the
migrants, but he had heard from Mr. Warren of Folkestone that the latter
had seen both Cynthia cardui (L.) and Aglais urticae (L.) there in small
numbers, and also a single Polygonia polychloros (L.). There were other
reports of C. cardui from the south-west. G. Prior had found Gonopteryx
rahmni (L.) and Inachis io (L.) numerous on the Chilterns recently, but
no Pug larvae on low herbs. A general discussion regarding the frequency
of larvae obtainable this year respectively in England and Scotland ensued,
and also on the scarcity this year in England of some species common last
year.

Dr. A. A. ALLEN stated that during an eight-day holiday in Dawlish,
Devon, an actinic 6-watt light trap was run each night from 13-14 to
20-21.viii. The weather was usually dry and mild but rain fell throughout
the night of 16-17.viii which was also very misty. Rain fell to a lesser
extent on 20-21.viii. Forty-three species of Macro-lepidoptera were thus
recorded in this residential area just outside the town; there were surpris-
ingly few Micros, but for this the capture of P. acroxantha compensated.
There appeared to be absolutely no second brood of Mythimna pallens (L.)
and M. impura (Hubner), a strong contrast to their abundance on a similar
date last year. Especially abundant species were Pieris brassicae (L.),
Noctua janthina (D. & S.), Apamea monoglypha (Hufn.) and Agrotis puta
(Hiibn.). Euplagia quadripunctaria (Poda) (Jersey tiger) was common during
the week both night and day, and four examples of Eupithecia phoeniceata
(Rambur) were taken; Cryphia muralis (Forst.) was also abundant. On his

44 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

return to Surrey he had found at rest on a shop front in Reigate on
26.viii.77 a specimen of Mormo maura (L.) (old lady moth) which had
recently decreased in numbers in this district. G. N. Burton reported that
on the Isle of Sheppey Euproctis chrysorrhaea (L.) (brown tail) had been
a veritable plague, causing rashes on children; 250 examples came to light
in a single night.

Messrs. W. GiLcHRrist, A. E. Stupss, S. WILLIAMS and G. R. ELSE
then gave an illustrated account of ‘The Leckford Survey’, both historical,
ecological and with illustrations of some interesting species of animals, a
plan and views. A duplicate list of the Lepidoptera of the Leckford valley
and chalk hills (No. 4 in the Leckford Record), sponsored by the John
Spedan Lewis Trust for the Advancement of the Natural Sciences, was
circulated. A large attendance and the number of questions showed that
this project evoked a lively interest.

22nd September 1977
The Vice-President, Mr. G. Prior, in the chair.
The Chairman welcomed Professor Ewan of Tulane University, New
Orleans, as a visitor.

EXHIBITS

Dr. A. A. ALLEN. — (i) Two specimens, male and female, of Banchus
volutatorius (L.) (Hym., Ichneumonidae), caught, along with a second
male, flying by day, 23.vii.1977, at Funton, Kent. The genus Banchus
belongs to the subfamily Banchinae, whose members are solitary endo-
parasites of lepidoptera iarvae, especially Noctuidae; the larva is attacked
before maturity but not killed until it has constructed its pupal chamber,
within which the parasite larva spins a characteristic black elongate cocoon.
The British species of Barchus are comparatively few in number. The
exhibit provided a good example of the sexual dimorphism often encoun-
tered in the group; the black-bodied female contrasts markedly with the
yellow and black male. (ii) One example (@) of Coelichneumon microstictus
(Gravenhorst) (Hym., Ichneumonidae) caught in a shop window, 22.vi.77,
at Dawlish, Devon. This appears to be a coastal species and quite local,
having been recorded from Cornwall, Devon and the Isle of Wight. In
common with the rest of the sub-family Ichneumoninae, Coelichneumon
attack mature larvae or prepupae of lepidoptera, in which they develop
singly, but the adult always emerges from the host pupa. (iii) A series of
Cryphia muralis (Forster) illustrating the wide variation of this moth, and
all captured 14-18.viii.77 at actinic light, Dawlish, Devon, the light being
run on the roof of a house covered with lichens.

Prof. J. A. Owen. — Two specimens of Phloeosinus thujae (Perris)
from Cupressus macrocarpa at Tooting, London, SW17, on 17th July,
1977; first discovered in Britain on Cypress in Kew Gardens.

G. Prior. — Two larvae of Eupithecia simpliciata Haworth (plain pug)
on common orache (Atriplex patula) from a salt-marsh at St. Helens,
Isle of Wight, now in final instar. They had undergone startling changes
in colour markings and skin-texture in earlier moults.

NOMINATIONS

The following, their names having been read a second time, were
declared elected members: Messrs. A. R. Barton, T. W. Wildridge, M. R.
Brown, M. R. Love and T. J. Daley. Mr. T. J. Daley signed the obligation
book.

ANNOUNCEMENTS

The Vice-President announced that the widow of Mr. George Holroyd,
a previous member, had presented a book belonging to her husband, viz.
W. E. Kirby Butterflies and Moths of the U.K., and Miss Wakely had
given Bradley, Tremewan, and Smith: British Tortricoid Moths Vol. 1;
Miss Wakely, daughter of the late Mr. Stanley Wakely, had also promised
to present a second album of photographs of field meetings, etc., compiled
by her father.

COMMUNICATIONS

Dr. C. G. pE Worms reported having seen, last week, Lysandra bellargus
(Rott.), the adonis blue, commonly; and also fresh L. coridon (Poda), the
chalk-hill blue, at Ranmore Common; both Messrs. FaircLouGH and
HILLIARD reported having seen Colias croceus Fourc., the clouded yellow,
in Surrey recently, but not in great numbers; Mr. R. F. BRETHERTON
mentioned that L. bellargus had in recent years made a recovery in the
North Downs and regained nearly the whole of its former territory there,
reaching Pewley Down in the extreme west. Mr. CHALMERS-HuNT had seen
a single Cynthia cardui (L.) (painted lady) at West Wickham in early
September.

Dr. SATTLER then gave an illustrated talk: ‘A lepidopterist in Hawaii’,
showing habitats and among other Lepidoptera, some remarkable photo-
graphs of Eupithecia larvae, which genus had speciated richly in that
group of islands and evolved unusual larval habits.

Numerous questions showed that the audience had been greatly interested
and the talk was applauded vigorously.

13th October 1977
The President, Mr. R. S. Tupss, in the chair.

EXHIBITS

Dr. A. A. ALLEN. — (1) Two examples of Enicospilus tournieri Snell
(2=ramidulus L.) (Hym., Ichneumonidae) caught, along with several others,
at actinic light, 14.viii.77, at Dawlish Warren, Devon. Although the testa-
ceous colour of the species is indicative of nocturnal flight, the exhibitor
caught a specimen on the wing at noon the following day. In common
with others of the sub-family Ophioninae, E. tournieri is a solitary parasite
of lepidopterous larvae; the host is attacked when immature but not killed
until it has constructed its pupal chamber. (2) A single 9 of Barichneumon
lepidus Gravenhorst (Hym., Ichneumonidae) bred 11.v.74 from a lepidop-
terous pupa dug 18.iv.74 from under Salix caprea at Salfords, Surrey. The
species is of the sub-family Ichneumoninae and is not uncommon overall,
but the exhibit was of interest as the female is very much less common
than the male; Perkins (1960) gives the status of the former sex of lepidus
as rare. This presents something of an anomaly for the disproportionate
sex-ratio of parasitic Hymenoptera usually gives rise to a predominance
of females over males. The exhibitor has however frequently obtained
males of the genus Mesochorus (Hym., Ichneumonidae) in much greater
numbers than the relatively scarce females. (3) A specimen of Evergestis
extimalis (Scop.) (Lep., Pyralidae) which was one of two examples caught
at actinic light, on a windy night at Funton, Kent. The species is local
and uncommon; Beirne (1954) gives its British headquarters as the Breck
district of Norfolk and Suffolk. (4) Ostrinia nubilalis (Hiibner) caught the
same night as the preceding species, two imagines, both male, being
obtained. As the larva of this moth hibernates, the exhibit resulted from

46 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

a larva having survived the drought of 1976, and this is of interest as
Beirne, 1954, p. 152, states that ‘dry summers, at the time of hatching [of
the larva] are said to be very injurious to the species’. See also S. Wakely.
1939, in Ent. Rec.. 51: 1-5.

A. M. EMMET. A specimen of Pulicalvaria piceaella (Kearfott) (Lep.,
Gelechiidae) taken at Woodham Walter, Essex, on 10.vii.77. It is believed
to be the fourth British example. The species is a native of N. America
and appears to have been introduced accidentally into this country. The
larva mines the leaves of spruce (Picea abies) in the autumn, overwinters
in a hollowed-out needle, and completes its growth in the spring. A search
was made at Woodham Walter on 2.x.77 and three tenanted spinnings
were found, presumed to belong to this species; one of these was exhibited.

ANNOUNCEMENTS

The Secretary confirmed to the meeting the Council’s decision to appoint
Dr. A. A. Allen Acting Librarian until the end of the year as Miss V.
Dick was unable to continue. Dr. Allen accepted. Lt.-Col. Emmet appealed
to members having annotated copies of the Guide to the Smaller British
Lepidoptera by L. T. Ford to submit their notes to him to enable fullest
possible new data to be included in the projected revised edition.

COMMUNICATIONS

Col. D. H. STERLING reported having taken Mythimna vitellina (Hubner)
at Winchester on the night of 9th/10th October, and a specimen of
Lithophane léautieri (Boisd.) there the previous week. Mr. R. F. BRETHER-
TON also reported having taken the latter species in Surrey, the moth
occurring in places where Cupressus macrocarpa was established. Dr.
C. G. M. DE Worms and Mr. J. Brown also reported this moth’s capture
in Surrey. Mr. E. S. BrapForpD reported disturbing specimens of the
following Lepidoptera whilst clearing out a shed in a garden: Agonopteryx
alstroemeriana (Clerck), A. heracliana (L.), A. nervosa (Haw.), A. arenella
(D. & S.), A. propinquella (Tr.), Endrosis sarcitrella (L.), Mompha ful-
vescens (Haw.), M. substrigella (Haw.), Hofmannophila pseudospretella
(Stainton) and a Tineid sp.

Dr. A. H. B. Rypon reported having seen numerous Rhopalocera
in his garden on Michaelmas daisies and Sedum flowers, including Vanessa
atalanta (L.).

Dr. A. A. ALLEN reported that the poor summer of 1977 seemed to have
retarded the appearance of the parasite Charops cantator de Geer (Hym.,
Ichneumonidae) by about two months; this may have been caused by the
delayed development of its hosts: Zygaena sps Cocoons of Z. filipendulae
(L.) collected at Dawlish, Devon, in late June 1976 produced a few
specimens of cantator in mid-July 1976 and a small number of freshly
emerged imagines of filipendulae were seen at the same time. However,
on returning to the site in late June 1977 neither cocoons nor adults of the
moth could be found; the former stage had always been well in evidence
at this time in previous years in a local area on the cliffs. The cocoons
were however obtained there in mid-August 1977 and examples of cantator
were bred from these at the end of the month. This provides an example
of how parasites are able to adapt to the behaviour of the host; sometimes
the parasite deliberately modifies the rate of the development of the host.
C. cantator attacks young larvae of Zygaena sps. but the host larva is not
killed until it has constructed its cocoon, inside which the parasite spins
its own.

Other members also reported their recent light trap captures and
discussed the comparative frequency of some species.

COMMENTS ON EXHIBITS

Mr. S. N. Jacoss stated that Ostrinia nubilalis was established in this
country where it fed on the roots of Artemisia (mugwort), and Lt. Col.
A. M. Emmet confirmed that he had noted it as established on the banks
of the Thames estuary.

Mr. E. S. BRADFORD reported having taken an example of P. piceaella
at light in his garden in Elstree in 1968 and had been given another taken
in 1967 by Mr. P. Goddard; the only other previous record was one taken
at Blackheath by Mr. Minnion.

Then followed a selection of excellent and varied colour-slides of birds,
plants and insects shown by Drs. A. A. Allen and W. H. Wain, and Messrs.
E. S. Bradford, Merrifield, G. Prior and R. W. Uffen.

10th November 1977
The President, Mr. R. S. Tusss, in the chair.

EXHIBITS

Dr. A. ALLEN. — (i) Two females of Agriotypus armatus Curtis (Hym.,
Ichneumonidae), a solitary ecto-parasite of Trichoptera, of which the
genera Silo and Goera are selected as hosts. These two examples were
obtained from the host cases found in the R. Pang, Bradfield, Berks.,
in the late winter of 1976. The adult armatus failed to appear at the
expected time of the summer months and were only obtained by resorting
to opening the cases and removing the perfectly formed insect from its
cocoon. The wings were fully developed, and the examples, although dead,
were readily mounted. The species parasitises the pupae and pre-pupae
of Trichoptera. In order to oviposit onto the host, the female armatus
enters the swiftly running water (the environment in which Silo and Goera
occur) and seeks out the hosts, which are usually attached to stones on
the stream-bed. The body-pubescence of the parasite traps air and enables
the insect to remain submerged for up to thirty minutes (Askew, 1971).
Parasitized cases may be recognised by the presence of a flattened, blackish,
ribbon of about 30 mm. length issuing from the affected host case; it is
formed when the parasite larva spins its cocoon inside the caddis-case, and
serves as the respiratory apparatus of the developing adult. Oxygen from
the water diffuses into the ribbon and ensures the parasite of a constant
supply; the insect dies if the ribbon is removed. The species appears local
but can apparently occur in large numbers at certain times (see Perkins,
1960); the exhibitor could not find the species during the winter 1976-7 in
this locality, inspite of finding many cases of the host. (ii) Two specimens
(3 2) of Agrypon flexorius Thunb. (Hym., Ichneumonidae) bred 6.vii
($) and 13.vii.1977 (2) from pupae of the Phycitinae (probably Phycita
roborella (D. & S.). The hosts were obtained as larvae, being beaten from
oak, 28.v.1977, in Vert Wood, East Hoathly, Sussex, and they pupated
before 15.vi. Although the identity of the host was not definite, some
imagines of roborella were bred mid-July from the larvae of which there
were about eight. The Anomoloninae sub-family attack the host larva
when young but emerge from the host pupa. A. flexorius has been recorded
from Phycita sp. before; the exhibitor obtained a third example, ¢, from
a third parasitized pupa.

R. FarrcLoucH. — A live specimen of Palpita unionalis (Hiibn.) found
on 10.xi.1977 outside the light-trap at Leigh, Surrey. The exhibitor had
not seen this migrant since the early 1960’s when it was fairly frequent.

C. Hart. — A specimen of Hippotion celerio (L.), the silver-striped
hawk, which was reared from a batch of ten young larvae (not British);
the exhibitor had four other pupae still to hatch. The larvae were
obtained from Mr. B. Betts at the AES Exhibition on Ist October, and
the larvae were reared on a mixture of Fuchsia and willow-herb. At a
temperature of 78° F., an average of 26 days were spent as larva and 14
days as pupa (slides of these larvae were shown later in the evening).

P. A. SoxoLtorr. — A short but variable series of the local moth Acleris
hastiana (L.) recently bred from sallow at Dungeness, Kent.
S. A. Wittiams. — A single specimen of Anthicus bifasciatus (Rossi)

(Col., Heteromera), a very local beetle, sieved from compost on the Bristol
municipal allotments.

ANNOUNCEMENTS

The President announced that a letter had been received from a visitor
to the Annual Exhibition expressing high appreciation of the work done
by the ladies responsible for catering. This sentiment was warmly echoed
by all present. The Hon. Secretary announced that the Chelsea Town Hall
had been booked for the Annual Exhibition next year on 28th October, it
having proved so satisfactory two years in succession.

COMMUNICATIONS

The President reported that on a visit to Fingringhoe Centre, south of
Colchester, he had been fortunate enough to see a pair of bearded tits
in the reeds there.

Dr. C. G. M. DE Worms commented on the diminished numbers of
Lepidoptera appearing at light recently, and Lt. Col. A. M. Emer stated
that Oporophtera brumata (winter moth) was already out in Essex. Other
members similarly reported recent observations of Hymenoptera and Lepi-
doptera, showing the season was drawing to a close, though Aglais urticae
(L.) (small tortoiseshell) and Inachis io (L.) (peacock) were today still
to be seen around London on the wing, and this evening a Tinea pales-
centella Stainton was taken indoors at the Alpine Club itself. J. Heath said
that the furthest north locality recorded for Lithophane leautieri (Boisduval)
was North Bucks.

Lt. Col. A. M. Emmet reported on a Field Meeting following the Annual
Exhibition, at Banbury Ridge and Woodham Walter, Essex.

A discussion of the 1977 Annual Exhibition then followed. The overall
attendance was higher than last year, despite the poor season that preceded
it.

Dr. A. A. ALLEN then exhibited slides, mostly on parasites of Lepidop-
tera. Messrs. C. Harr and P. HamMMmonp also exhibited excellent slides
showing various insects and flowers.

24th November 1977

EXHIBITS
Dr. A. A. ALLEN. — Of twenty-one larvae of Cucullia chamomillae
(D. & S.) (Lep., Noctuidae), all taken on Tripleurospermum maritimum
(scentless chamomile) at Dawlish Warren, Devon, on 19th June, 1977, eight

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 49

contained parasites belonging to two species of Ichneumonoidea, four of
each parasite species; these, exhibited, were (i) two examples (4, 2) of a
Rogas sp. (Hym., Braconidae) in the circumscriptus Nees species group;
the four young host larvae of chamomillae were killed (mummified) by
the solitary endoparasite 1-2.vii, and the adults were bred 10.vii (2 6)
and 1l.vii. (2); the fourth mummified host failed to produce a parasite.
Both the males hatched in the normal manner from a hole chewed
in the posterior end of the mummy, but the female was of exceptional
interest, making its exit from a hole at the front end of the mummy, just
behind the head, the first such case in the exhibitor’s experience. Rogas
sp. are often reared from young larvae of Noctuidae, and a species of
this group has been recorded from Cucullia verbasci (L.). (ii) two specimens
(both 9) of Campoletis annulata Gravenhorst (Ichneumonidae) from a
total of four females obtained from four young chamomillae larvae. The
host larvae were killed 22-25.vi.77 (one killed each day) when only about
12 mm. in length. The parasite-maggot devoured the entire host’s contents
before constructing its brownish, rather elongate, cocoon among the
vegetation, attaching the skin of the host to its exterior. The adults were
bred on 3-5.vii.77. Campoletis sp. number about a dozen in Britain; the
present is one of the more widespread but most records are for the adult.
The exhibitor had not heard or seen mention of any host for C. annulata.

R. F. BRETHERTON. — A couple of graphs of moth attendances at his
moth-trap at Bramley, Surrey, for 1976 and 1977.
Lt. Col. A. M. EmMmMet. — Mined leaves and statistics illustrating the

abundance and scarcity in 1977 of certain species of Nepticulidae (Lep.)
mining leaves of oak. Four leaves were shown: (i) from Madingley, Cambs.,
collected on 19.xi, a leaf containing about 38 mines of Ectoedemia
quinquella (Bedell) and three of E. subbimaculella (Haworth); (ii) from
the same locality and date: a leaf containing 18 mines of E. quinquella,
30 of E. subbimaculella, one of Heliozela sericeella (Haworth), three of a
Phyllonorycter sp. and the external feedings of three other larvae belonging
to two species of Microlepidoptera; (iii) from Mistley, Essex, collected on
26.x.77, a leaf containing 30 mines of E. subbimaculella and one of E.
quercifoliae (Toll); (iv) the stastistics, covering 784 mines in 116 leaves
from three localities where the exceedingly local and scarce E. quinquella
occurs, showed that in 1977 that species comprised 51% of the mines,
E. subbimaculella 46.7% and E. quercifoliae only 2.3%; in most years
E. quercifoliae and E. subbimaculella are found in more or less equal
numbers. It was suggested that in 1977 there could be anything up to a
million mines of E. subbimaculella on a single mature oak in numerous
favoured localities, and the same was true of E. quinquella, but only in
its very restricted haunts. E. quercifoliae, however, had been scarce every-
where. A table was also shown of the leaf-mining species which had been
unusually common or scarce in 1977, together with their larval season in
relation to the drought of 1976. The table showed that many species whose
larvae had fed during the summer while the drought was at its height,
were more scarce than usual this year, and that others whose larvae had
fed in the autumn after the drought had broken were common; there
were, however, exceptions to these generalisations.

J. HEATH. Old cases of the psychid Narycia monilifera (Geoffroy)
from crevices in the bark of a sycamore tree in Ramsey Road, St. Ives,
Huntingdon, Cambs. (VC.31). These were found by Mr. Brian Elliott
who drew the attention of the exhibitor to them. A new vice-county
record. It is found in adjacent Cambridgeshire (VC.29) and Bedfordshire
(VC.30), as well as in much of south and south-east England.

P. A. Soxotorr. — A dwarf example of Xanthorhoe fluctuata (L.),
taken at light on 15.viii.76, wingspan only 16 mm. (typical range of wing-
span: 27-31 mm.). Perhaps attributable to the drought.

R. W. J. Urren. — A series of Coleophora machinella Bradley with
their larval cases, from Botley Wood, South Hampshire, found by Dr. J. R.
Langmaid. The specimens had been reared from Achillea ptarmica (sneeze-
wort) and constituted the second British record of the species.

COMMUNICATION

Mr. Roche produced a memorandum from Dr. P. J. L. Rocue, a resident
of Andorra on a valley in that country in which 67 different species of
Rhopalocera had already been taken and suggesting that a survey of it
might be a long-term project. Members interested were invited to read the
memorandum and get into touch with one of the brothers Roche with
a view to holding European field-meetings at this site, and Dr. Roche
could organise hotels, etc.

The main event of the evening was a discussion of the 1976 drought
and its after-effects. Some of the exhibits had illustrated this subject. The
President began the discussion with a few meteorological statistics, e.g. on
the January to August rainfall in the years 1976 and an average year
were respectively 5.27 in. and 17.25 in., but in the month of September
1976 alone 6.2 in. fell. The last four months of 1976 brought up the
annual total to about 1 in. only less than the yearly average. Not only
was there a drought, there was a heatwave: in August the temperature
had stood at 90° F. day after day.

Lt. Col. A. M. Emmet’s contribution is summarised under his
exhibit above. The next speaker, J. HEATH, said that 1976 was the last
and worst of a series of drought-years; for the last three or four years
walking in Monks’ Wood in light shoes had become possible owing to
the drying out of the soil, though previously this had not been so. Probably
the local extinction of Carterocephalus palaemon (Pallas) (chequered
skipper) was attributable to this cause. A decline in numbers in members
of the genus Micropterix Hiibner was also probably due to the same recent
climatic tendency.

E. S. BRADFORD opined that such fluctuations must have occurred several
times during the last thousand years. A. E. Stusps mentioned the very
extensive heath fires, particularly those that had devastated Chobham and
Thursley, Surrey. Although fire was a regular feature in the formation of
heathland, as heather grew again on burnt ground, there was a fear that,
when they were so extensive, not enough high heather would be left for
the survival of some insect species. Some species of Diptera had been
affected by the drought, the crane-flies having suffered; certain flies
associated with dung seemed to have extended their range further north

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 51

in Britain than usual and this probably was due to the south becoming
less favourable.

G. Prior. — Larvae of the genus Eupithecia (pugs) reacted variably to
the drought: early-feeding species seemed unaffected, and rather surprisingly
their oval stage was not desiccated. The leaf and needle-feeding species
were also unaffected, at least they appeared in equal numbers in 1977.
However, late summer feeders, particularly those on ragwort and other
herb-flowers, were less numerous in 1977 though these included the very
commonest of our pugs, e.g. E. centaureata and absinthiata. In 1977, owing
to the drought ragwort flowers all dried up by August instead of remaining
fresh and edible into autumn.

A general discussion then followed; Mr. J. HEATH thought that numbers
at light traps did not necessarily indicate numbers of a given species
surviving, as cold conditions inhibited moths from flying to light, contrasting
with the abundance of arrivals in very hot weather. Dr. C. G. M. DE
Worms remarked on the greater numbers of moths coming to light in
Western England than in Eastern England in 1976; both regions were
affected by heat but the west less affected by drought.

Opinions differed on whether Argynnis paphia (L.) (silver-washed
fritillary) had had an equally good year in 1977 as in 1976.

R. FarrcLouGH had counted 2,600 examples of Acleris cristana
(D. & S.) in 1976, but much fewer in 1977. He thought the reduction in
1977 might be rather due to rain and cool conditions than to the drought
in 1976.

A discussion on the mortality of bees in hives ensued: its causes were
thought to be the exhaustion of honey supplies combining with a cool,
late spring in 1977.

Many other members contributed to what proved to be a highly
interesting debate.

8th December 1977
The President, Mr. R. S. Tupss, in the chair.

EXHIBITS

A recently received review copy of P. Hammond’s book of dragon-flies
was passed round for members to see.

Dr. A. A. ALLEN. — (i) Two pairs of Apanteles sp. (Hym., Braconidae);
each pair consisting of a common species and a closely related species only
recently separated from its partner. The new species were described by
Nixon, Bull ent. Res., 63, 169-230 (1973). (a) A. fulvipes Haliday and
A. acasta Nixon: both are gregarious species. A. fulvipes is one of the
most frequently encountered sp. of Apanteles and usually obtained from
the Noctuidae. The exhibited examples represented a fraction of a brood
of about 70 individuals bred 5.vi.1974 from a larva of Allophyes oxyacanthae
(L.) (Lep., Noctuidae) obtained when young on hawthorn at Salfords,
Surrey. The host was killed as a pre-pupa on 22.v.74, on which date the
Apanteles spun their cocoons. The exhibitor had also obtained fulvipes
in abundance in the mid-sixties from mature larvae of Diloba caeruleo-
cephala (L.) near the same locality. In recent years, however, larvae of
this latter moth did not appear to be attacked by fulvipes; they were
however parasitized by other Ichneumonoidea. A. acasta resulted when
twelve cocoons, attached to which was the dead host, were taken on hazel,
30.iii1.74 at Reigate, Surrey, and the adults bred 11.iv.74. Since the species
has only been described recently its distribution is not certain; it has

52 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

probably been overlooked as fulvipes. Hosts from which acasta has been
recorded include A. oxycacanthae and Diarsia mendica (Fabr.). (b)
Apanteles vitripennis Curtis and A. mygdonia Nixon: these are both
solitary parasites. A. vitripennis attacks a wide range of immature larvae
of Lepidoptera and is widely distributed. The exhibit showed (a 2) bred on
4.vi.77 from a young larva of D. caeruleocephala found on 24.v.77 at
Salfords. The parasite larva appeared 27.v, and the host died a few days
later. A. mygdonia is very similar to vitripennis and, as before, has probably
been mistaken for it in some instances. The 2 displayed was bred 3.iv.77
from an immature larva, probably of Alcis repandata (L.) (Lep., Geome-
tridae), beaten from privet in a wood at Salfords, Surrey, 6.11i.77. The
parasite larva spun its cocoon 15.i1i.77. (ii) A female specimen of Zimmeria
dirus Wesmael (Ichneumonidae) bred 20.v.1967 by Mr. P. Cordell from a
larva of Eriogaster lanestris (L.) (Lasiocampidae). Two such larvae were
found, both full-grown, at Wareham, Dorset, 12.vii.1966 and they pupated
about a week later. One cocoon produced the expected moth the following
spring. Z. dirus, bred from the other, is a rare species, sec. Perkins, 1959;
this may in part be attributable to the scarcity of E. lanestris the only host,
from which dirus has been obtained. The exhibitor expressed his thanks
to Mr. Cordell for the gift of the set parasite. (iii) A selection of biscuits,
mainly plain chocolate wheatmeal, infested with larvae and larval working,
of probably Plodia interpunctella (Hibn.) and/or Ephestia elutella (Hibn.)
(Pyralidae). The biscuits arrived in fresh condition at a clerical laboratory
in Reigate, Surrey, vi.1977! a few were stored away and forgotten until
5.xil.77, whereupon their present condition was discovered. On 15.vi.1977
the exhibitor had caught adult specimens of P. interpunctella (especially)
and E. elutella in the very same laboratory and had encountered both
species on previous occasions there. The moths were evidently breeding
in the laboratory and the biscuits would afford suitable nourishment. A
specimen of each moth caught on 15.vi was also exhibited, together with
one of the larvae extracted from the fouled biscuits. Recourse to Beirne
(1954) revealed the larva was almost certainly interpunctella.

K. GuIcHARD. — Some insects to illustrate his talk that evening, with a
é Qaboosia splendens Popov (Orth., Acrididae), the largest grasshopper in
Arabia; observation of the former had revealed the hitherto unknown
purpose of its Krauss’s organ, namely stridulation.

B. C. Jackson. — Unidentified beetles found at Barking, Essex, but
imported in containers from abroad, the smaller of two types feeding on
ginger from India.

Mr. Day.

COMMUNICATIONS

With regard to the oak-leaf mines mentioned at the previous indoor
meeting, Mr. S. N. A. Jacoss stated two oaks in his garden had no mines
at all this autumn, as he had been able to inspect fallen leaves; however,
these oaks had last year had an abundance of cynipid galls. Lt. Col. EMMET
observed that this year galls were everywhere scarcer than last year; he
had heard from an observer in Bournemouth, Mr. S. C. S. Brown, that
Ectoedemia subbimaculella (Haw.) was very common there too, but E.
quercifoliae (Toll) was absent.

Mr. K. GuicHArD then gave a talk, illustrated with transparencies,
entitled ‘A naturalist in Oman’. This described his recent expedition made
with Mr. P. Granville White in September and October to Oman, and
the previous visit made in April of the preceding year to a different part
of the same country. The landscape photographs of the two regions showed
a striking contrast; the Jebel Akhdar, Musandam Peninsula, and Jebel
Aswad, near Muscat in Eastern Oman were dry, whereas the seaward
slopes of the Qara mountains at Dhofar in south-west Oman were com-
pletely verdant with grass and short trees, due to an exceptional climatic
conjuncture, the monsoon favouring Dhofar every summer. Photographs
were however also shown of the northern, desertic slopes of these moun-
tains, where the frankincense trees grew in a restricted area. Transparencies
showed some characteristic habitats, vegetation, flowers, butterflies, larvae,
and other interesting creatures of all these localities. Appreciation was
shown by the audience in the usual way of the lecturer’s most interesting
talk.

12th January 1978
The President, Mr. R. S. Tusss, in the chair.

EXHIBITS

Rev. D. AcGassiz. — A series of Acleris hastiana (L.) (Lep., Tortricidae)
from County Cork, Ireland.

Dr. A. A. ALLEN. — Two females of the species Argypon clandestinum

Gravenhorst (Hym., Ichneumonidae), obtained on the wing in the day-
time at Salfords, Surrey, on 23.vii.1976, and at Plaistow, Sussex, on
31.vii.1976. The sub-family, Anomaloninae, to which it belongs, are all
solitary endoparasites of lepidopterous larvae; the young host is attacked
but the adult parasite emerges from the host pupa. A. clandestinum
appears to be moderately common in the southern half of Britain and, to
judge from published host lists, seems to be particularly attached to the
genus Eupithecia. Also two examples (¢ and @) of the common species
Amblyteles armatorius Forster (Hym., Ichneumonidae). The g was caught
by the exhibitor at Teignmouth, Devon, on 20.vi.1977, while the 2 was
bred on 1.vii.1977 by Mr. P. Cordell from a larva of Noctua pronuba
L. (Lep., Noctuidae) that he found at Nutfield, Surrey. The species belongs
to the sub-family Ichneumoninae, all of which emerge, as adult parasites,
from the host’s pupa. The exhibit also served to illustrate the degree of
sexual dimorphism often found within this sub-family.

Lt. Col. A. M. Emmet. — A leaf of alder (Alnus glutinosa) collected
by Dr. Daphne Levinge at Whinning, Portlick, Glasson, Co. Westmeath,
Eire, on 13.ix.77, containing a mine and subsequently spun fold considered
to have been made by Caloptilia falconipennella (Hiibner), a species of moth
not previously recorded from Ireland. A second alder leaf, collected by the
exhibitor at Ballynahinch, Co. Galway, on 16.x.76, containing two mines
and a spun roll made by Caloptilia elongella (L.) was shown for comparison.
The differences between the larval feeding habits of the two species were
described.

Col. D. H. STERLING. — A specimen of Epischnia bankesiella (Richard-
son (Lep., Pyralidae), taken to light on Durleston cliffs, near Swanage,
Dorset, at the field meeting of 18th September 1976, only recently identified.
The exhibitor suggested that this rather late date might mean that the
species was bivoltine, at least in 1976. It is a rare and local species.

Dr. C. G. M. pE Worms mentioned that there were again records of the
moths Apocheima pilosaria (D. & S.) and Agriopis leucophaearia (D. & S.),
both more usually captured after the New Year, coming to light before
Christmas in Southern England. The capture of the rare Trigonophora
flammea (Esper) by Dr. Peak in Jersey was especially noteworthy among
other interesting captures which he had recently made. Mr. L. K. Evans
reading a cutting from the Daily Mail regarding a new law introduced in
Belgium by the City Council of that country’s capital penalising any person
who failed to destroy ‘caterpillars, their eggs and their nests’. Col. D. H.
STERLING reported that the capture at Winchester of a single specimen of
Epiphyas postvittana (Walker) (Tortricidae), only the second known record
from Hampshire. The species is now somewhat commoner in Devon and
Cornwall. Circumstances seemed to indicate that it had bred up on Coleus
plants, some of which having been reared from seed in a near-by green-
house, were growing in the window-box of Mr. George Else. He also
reported an example of Idaea seriata (Schrank) found on 7th January, an
exceptionally early date. Other members reported having seen umbellifers
flowering in January.

Mr. C. G. Rocue then gave an illustrated talk entitled ‘An Island called
Australia’, describing his own three-months’ travels single-handed in a
small car from West to East and from South to North of the continent,
and concentrating on lonely and unspoilt habitats of which there were
many excellent transparencies; also some good pictures of flowers and a
few of animals and birds. The number of questions at the end showed that
the lecturer had greatly interested his audience.

In comments on exhibits afterwards, some members doubted whether
the above mentioned capture of Epischnia bankesiella Richardson really
meant that the species was bivoltine, but rather that it had a single extended
emergence. Mr. CHALMERS-HUNT stated that the larva was slow-growing
and he had bred some and found that small larvae found in May were
full-grown at end of June or early July; and Mr. R. F. BRETHERTON recalled
having taken several examples of the moth at Portland on 10th August,
1972.

The President, Mr. R. S. Tupsss in the chair.

EXHIBITS
Dr. A. A. ALLEN. — (i) A few specimens of the gregarious endoparasite
Apanteles inclusus Ratzeburg (Hym., Braconidae), bred from two larvae

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 55

of Euproctis similis (Fuessly) (Lep., Lymantriidae). The larvae were captured
by Mr. G. King around late June 1977 in Lichfield, Staffordshire. In mid-
July the hosts spun their cocoons in the usual way, but on 26.vii.1977
several larvae of the parasite appeared from each of the host pre-pupae,
spinning their rather satiny-white cocoons within that of the hosts. The
adults were bred 31.vii-3.vii.1977. A. inclusus is of interest as it closely
resembles its near relative Protomicroplitis connexus Nees; both attack
Euproctis spp. and both kill the host as a pre-pupa, spinning their cocoons
in that of the host. A. inclusus, however, appears to be considerably less
common than the often abundant P. connexus and as these are the only
examples of inclusus the exhibittor has seen, he was most grateful to Mr.
King for sending the cocoon. (ii) Two examples (4 and 2) of one of the
commonest ichneumonids, Pimpla instigator (Fabricius) The 2 was
obtained in the light-trap (probably as a casual visitor) of Mr. P. Fairclough
on 14.ix.1977 at Leigh, Surrey, while the exhibitor swept the ¢ from rough
grass at Dawlish Warren, Devon, 15.viii.1977. Points of interest of the
exhibit were the absence of the constricted gaster (present in many
Parasitica), the entirely reddish legs, and the filiform antennae, providing
a marked contrast to the overall stout build of the insect. An additional
point of interest was that in captivity, P. instigator exudes a pungent
Tepelling odour, perhaps of a protective nature. P. instigator parasitises
pupae of a wide range of Lepidoptera.

J. T. DaLtey. — An example of Erebia ligea (L.) (Lep., Satyridae) (the
Arran brown) captured among many E. aethiops (Esper) by the exhibitor
on 5th July 1969 on a desolate moor in Scotland near a wood (shown at the
1977 Annual Exhibition but not identified as this species then), only authori-
tatively determined as such quite recently. The exhibitor had only twice
been abroad to collect butterflies and each time had done so in S. European
localities where this species did not occur, so a possibility of confusion of
locality was ruled out.

B. GOATER. — (i) A series of the red aberrations of Tyria jacobaeae (L.)
(Arctiidae) presented to the Society by our member, Mr. R. W. Weston,
who developed the strain. (ii) Two males and two females of Eriopygodes
imbecilla (Fabr.) (Noctuidae) bred ab ovis. They are the first specimens
to have been bred in Britain; a female was obtatined flying by day in July
1977, which laid six eggs. From these six moths were bred in late October,
the larvae feeding at room temperature on withering leaves of dandelion
(Taraxacum). A pairing was obtained and about 250 eggs were laid and
larvae distributed to a number of members of the society, some of whom
have already obtained moths. The exhibitor’s own larvae, again kept at
room temperature, are pupating at the present time. (iii) Two full-grown
larvae of E. imbecilla. In reply to questions, the exhibitor stated that he
surmised that in a wild state the larva was nocturnal and polyphagous and
would hibernate, the moth being univoltine; tthe favoured wild foodplant,
however, might be Viola hirta, which was common on the breeding-ground
in Monmouthshire.

OBSERVATIONS ON EXHIBITS

Mr. C. Hart remarked on the bulky abdomens of the freshly hatched
females of Eriopygodes imbecilla (F.) and wondered whether they succeeded
in flying. Mr. Goater replied that the females had on several occasions
been taken on the wing, but that when this happened the abdomens had
contracted, doubtless due to having laid many eggs. Mr. J. HEATH reported

56 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

that Bohemian reports on the habits of this moth were that the males
were exceedingly abundant but did not mention capture of females. Mr.
Goater repeated that he himself had taken females on the wing by day; at
night it appeared that a second flight occurred not until 2 a.m. and only
males came to light; he would not like to say that this observation
constituted an absolute rule.

After the reading of the minutes of the previous Annual General
Meeting, the President referred to the resolution passed at the Special
General Meeting and stated that this matter would be raised in the
Treasurer’s Report.

COUNCIL’S REPORT

During 1977 61 new members were elected, while in the same period
the Society suffered the loss of six members by death and 14 by resignation.
19 members were also struck off membership under the provisions of
Bye-law 14(b). We have thus a welcome net increase of 22 to the member-
ship which now stands in the region of 700. We have elected two of our
most distinguished members to the Honorary membership: Dr. H. B. D.
Kettlewell in February 1977 and Mr. E. W. Classey in January 1978. The
Annual Dinner was again held at Imperial College; it was attended by some
79 members and their guests, five more than last year.

The Annual Exhibition was once more held at Chelsea Town Hall. It
was well attended, some 350 members and guests signing the attendance
register. It was felt by most of those present that this year the exhibits
were outstanding, they included some insects new to the British Isles.

A new Christmas Card was produced and for its design we are again
indebted to Mr. R. Dyke. The sale of the cards was once more the
responsibility of Mr. M. Ventom and it is thanks to his energy and that of
his helpers that all our stocks of past cards, as well as a large proportion
of this year’s cards, have been sold.

Nineteen Indoor Meetings on varied subjects were organised by Mr. G. R.
Else and were well attended. Mr. E. H. Wild arranged 15 well distributed
and interesting Field Meetings, six of which were two day meetings.

During the year substantial progress has been made towards the publica-
tion of a new and up-to-date edition of Ford’s ‘Guide to the Smaller British
Lepidoptera’; it is hoped that this will be published in the Autumn of
1978. The Council feels that a great help towards its early publication
has been the generous financial donations made by some of our members
and would welcome further financial assistance from the membership for
this most worthwhile enterprise.

The Council wishes to thank Mrs. Lois Parker and Mrs. Bettina Prior,
and the wives and daughters of members, for again organising and providing
the excellent refreshments at the Exhibition; these again contributed to
the success of the event and helped to defray its cost. The Council also
wishes to thank Dr. B. J. MacNulty and Mr. K. G. Evans for their untiring
efforts in once more organising the two successful events, the Annual
Dinner and Exhibition.

TREASURERS REPORT, 1977
The Accounts for 1977 have been approved by our auditors, Mr.
Messenger and Mr. Stoughton-Harris, and copies are available here for
inspection. I thank them warmly for completing the audit so promptly, and
also Mr. L. J. D. Wakely for his untiring management of the subscriptions
side of the work.

PROC. BRIT. ENT. NAT. HIST. soc., 1978 Si

We have had another good year. The Income and Expenditure Account
shows a surplus of £484; and in addition we have received a legacy of
£100 from our late member Sir Eric Ansorge, and gifts of £500 and £100
from members who wish to remain anonymous. These I have placed to
reserve, in order to help to pay for the forthcoming revised edition of
Ford’s ‘Guide to the Smaller British Lepidoptera’, to which Council has
decided to devote them.

The surplus on Income and Expenditure Account is due to several
circumstances, not all of which are likely to be repeated; we have had a
year with no unexpected expenditure but much unusual income. Though
postage and other administrative costs have continued to rise steeply with
inflation, the cost of printing the Proceedings, which is by far our largest
single item, has gone up much more slowly, while there has been a boom
in sales of back numbers. As a result, the grant needed by the Publications
Account has fallen by £140 for the first time for many years, though it was
still over £1,000. Christmas Cards showed a useful profit of £43, after
covering the cost of printing a new card, which we did not have in 1976.
We also covered the cost of the Annual Dinner, though the surplus of £57
shown in the account was largely due to recovery of an over-charge
which caused a loss in 1976. As in 1976, a good part of the hire of Chelsea
Town Hall for the Annual Exhibition was met from the gain on sale of
refreshments skilfully managed by Mrs. Prior and her team. The Exhibition
also provided the opportunity for a sale of unwanted cabinets, boxes and
equipment which contributed no less than £163. Finally, subscriptions were
up by £72: this is a balance between the welcome increase in membership
and the very unwelcome continuance of excessive arrears in payment by
some 50 other members.

Turning to the balance sheet, we have added 500 Imperial Metal
Industries shares to our investments, at a cost of £260; and the Standard
Investment Trust was taken by the Prudential Assurance Company, in
which we therefore now hold 843 5p shares, whose market value is consider-
ably greater than that of our old holding. I have not invested the large
bank deposit balance, £1,821, in view of the expected need to use most
of it during 1978 to finance the new edition of Ford’s ‘Guide’, which I
have already mentioned. On the liabilities side, the Housing Fund has
increased by receipt of interest to nearly £1,700, and Reserve Fund, with
added interest and the gifts I have mentioned, to over £2,000. The balances
of the Library and Hering Memorial Funds have also grown slightly
because they spent rather less than their income.

I make no prophecies about results in 1978. Some of the windfall income
of 1977 is not likely to be repeated.. Administrative costs will certainly go
on rising. Much extraordinary expenditure is also needed: for shelves and
binding for the Library, on Hills unit cabinets if we can get them, on
duplicating equipment which we at present lack, and biggest of all, for
the new edition of Ford’s ‘Guide’. We aim to recover from sales the cost
of this, as we have done very handsomely on the first edition published
in 1949; but it will certainly be some years before we break even. Because
of these uncertainties, Council considers that the power which was given
to it last year to vary subscription rates for a calendar year ahead without
summoning a Special General Meeting should be retained, subject to further
review a year hence. As things are, I think it unlikely that we shall need
to use this power in 1979; but prudence requires that we should be able
to act quickly if later action on this becomes necessary.

EDITOR’S REPORT

Our 1977 Proceedings were again printed in two double parts, appearing
this time in May and October. The index for the year is in the press and
will be distributed shortly. We have continued along similar lines to those
of 1976; in both years there have been 128 pages of text and a liberal and
varied supply of illustrations. About one-tenth of the year’s matter dealt
with foreign lepidoptera; the other nine-tenths dealt with British insects or
general matter. Lepidoptera received more attention than any other order,
with diptera a good second, and parasitic hymenoptera particularly well
expounded in the indoor meeting reports. Reports on indoor and field
meetings together occupied about one-third of the volume. Short notes,
contributed as such, have been lacking this year; but the reports on the
indoor meetings continue to give abstracts about exhibits and communica-
tions by members; these together with the field meeting reports have
provided a great variety of observations, so that our publication cannot
be said to lack this feature except in a formal sense. An innovation was
made in introducing a feature entitled ‘Entomological Misadventures’, to
consist of light-hearted short narratives. Further contributions to this
series are invited and if few or none are received one must conclude that
our members are invariably fortunate and pursue their hobby or profession
most uneventfully; or alternatively cannot bring themselves to tell of their
misadventures. It appears from comments received that readers are satisfied
with our Proceedings as now published and it is therefore proposed to
continue along the same lines for another year at least. Thanks are again
due to the editorial assistants Prof. T. R. E. Southwood, and Messrs. T. G.
Howarth, M. Tweedie and R. W. J. Uffen, and to our printers Messrs.
Charles Phipps Ltd.; and not least the contributors without whom the editor
would edit in vain and the printers have less employment.

CURATOR’S REPORT

The past year has been one of satisfying progress in nearly all spheres
of activity. A further re-arrangement of cabinets and equipment allows
members more space and makes things easier for everyone.

Work on most orders is progressing very well. The lepidopterous larvae,
which are in fine order, have been completely re-housed in two Hill units
by the energy of Mr. W. Parker. The re-organisation of the British and
European Rhopalocera is gradually taking place. Members now travel and
collect abroad much more frequently, and the Society, in line with this,
hopes to have the Palaearctic lepidopterous fauna well represented. We
have been very fortunate in the donation to the Society of a collection of
Scandinavian lepidoptera, both Rhopalocera and Heterocera, by one of
our members, Mr. S. Torstenius, who lives in Sweden. The negotiations and
transport of the specimens is being undertaken by Mr. C. B. Ashby. The
first selection of lepidoptera, in beautiful condition, were shown at the
Annual Exhibition at Chelsea Town Hall on 29th October 1977. I would
like to thank Mr. Torstenius and Mr. C. B. Ashby for their efforts on
behalf of the Society. I must also thank another of our members, Mr. L.
McLeod, who kindly presented the Society with four store boxes of
Microlepidoptera, amongst which were some uncommon and rare species.

The response made during 1977 for duplicate specimens and sub-species
of the British Rhopalocera has been very poor, and I appeal once again
to members for duplicate specimens. Those species most required are:
Luperina nickerlii (Freyer) s.sp. Knilli Boursin, Trisateles emortualis (D. &
S.), Eupithecia phoeniceata (Rambur), and Spargania luctuata (D. & S.).

Work is continuing on the new Diptera cabinet, which is being laid
out with more space allowed for new species and more specimens. The

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 @ 61

Tipulidae especially, have been much enhanced over the past year by the
admirable work of Mr. P. J. Chandler and Mr. A. E. Stubbs.

The incorporation of the Massee collection of Coleoptera is progressing
well in the capable hands of Mr. R. D. Weal, and when completed
a start will be made on the re-housing of the Joy colection of Coleoptera.
I am grateful to Mr. Weal who also collected and brought back from the
National Museum of Wales some store boxes containing coleoptera
belonging to the Society.

Three small cabinets, a number of store boxes and various items surplus
to requirements were sold at the Annual Exhibition by Mr. W. Parker,
who I must thank once again for undertaking the task of selling the same
and realising the handsome sum of £145.

A microscope placed on loan by the late Mr. A. E. Gardner and of no
known whereabouts has, I am pleased to report, been returned by the
person whom it was loaned.

Members have taken advantage of the number of duplicate specimens
made available during the year and some specimens of a few species have
been loaned to specialists for research.

The thanks of the Society are due to the following members for donations
to the collections: Prof. J. Owen (Coleoptera), Mr. R. D. Weal (Coleoptera),
Mr. P. Sokoloff (Coleoptera), Mr. S. A. Williams (Coleoptera) and Mr.
E. S. Bradford (Microlepidoptera). Also, thanks must go to Mr. M. Tweedie,
Mr. W. Parker and Mr. A. A. Allen for the contribution of a number of
colour transparencies on various subjects to the Society’s collection. This
increasing stock of transparencies is now being catalogued by Mr. E. H.
Wild.

Lastly, I must thank the assistant curators who have borne the brunt of
the work on collections during the year.

LIBRARIAN’S REPORT

During the year Miss V .Dick resigned and in October I was appointed
her successor.

I am pleased to say that considerable progress has been made towards
sorting out the library, an exercise which at first seemed insurmountable.
In particular, many of the interesting journals received by the Society have
been classified and shelved and are now readily accessible to members, who,
it is hoped, will take advantage of the more spacious arrangement.

There still remains a considerable amount of work to be done, and the
offer of one or two members to act as assistants during the course of this
year would be very welcome. Two matters of immediate concern are,
firstly, the requirement of more shelves, and secondly the need to bind
certain of the journals.

For a library to be run efficiently, books must be returned by the stipu-
lated date; far too many members have borrowed books and failed to
return them on time, despite annual requests at each AGM. In some cases
the books are literally years overdue. The matter is serious, for while
depriving other members of the opportunity to read the books, the mis-
conduct strikes a distinctly discordant note with the standards set by the
Society. I would remind offenders that under the bye-laws, a fine is
chargeable on overdue books.

Before naming some of the books generously donated to the library, I
should like to thank Messrs. G. Prior and E. Bradford for their invaluable
guidance and assistance during my induction period to this office. In reading
out some of the books donated, I must apologise for any omissions and
trust that the donors are not unduly offended. Omitting some reprints of
some value, the books include: British Tortricoid Moths, Vol. 1, by J.

62 ‘es PROC. BRIT. ENT. NAT. HIST. SOC., 1978

Bradley, W. G. Tremewan and A. Smith, donated by Miss Wakely. Butter-
flies and Moths of the U.K., by W. G. Kirby, donated by Mrs. Holroyd.
An Atlas of the Marine Mollusca of the British Isles, by National Environ-
ment Research Council, donated by Mr. J. Heath. Dragonflies of the
British Isles, by C. Hammond, donated by the author. The Scientific Results
of the Oman Flora and Fauna Survey 1975, by various authors, donated
by Mr. E. P. Wiltshire. I must also mention receipt of Alexanor and other
publications, regularly donated by Mr. S. N. A. Jacobs.

REPORT ON THE HERING MEMORIAL RESEARCH FUND IN 1977

No reports have been received from recipients of awards in the year
1976-77.

A sum of £200 was available for grants for the year 1977-78. A request
early in the year for an immediate payment to defray the cost of the
publication of a paper was rejected, since awards are not normally made
for this purpose or ahead of the closing date for applications.

Subsequently there were three applicants, all of whom are receiving
awards of £160, they are follows: —

(i) S. Trifourkis, for travel expenses to study Mycetophilidae (fungus-
gnats) in the field. Since receiving his grant, Mr. Trifourkis has had a
Ph.D. degree conferred on him for his work on this project. He is con-
tining his research and is currently writing a paper on the taxonomy of
the group.

(ii) M. R. Wilson, of the Department of Zoology, University of Cardiff,
for travel expenses to collect larval mines of the British Phyllonorycter
(Lep., Gracillariidae). He is working on a key to the pupae, which he will
make available to Dr. I. A. Watkinson for inclusion in the section on that
genus in The Moths and Butterflies of Great Britain and Ireland, Vol. 2.
The purpose of the key is to help lepidopterists to record species from the
early stages alone. It will also be of value to students of the parasitic
Hymenoptera wishing to identify hosts which have been killed in the pupal
stage.

(iii) A. M. Emmet, towards the cost of travel to the extreme north of
Scotland to study lepidopterous leaf-miners restricted to that area. Three
of these, Bucculatrix capreella Kogerus, Parornix alpicola (Wocke) and P.
leucostola Pelham-Clinton, have life-histories which are unknown or
imperfectly known and which need to be described in The Moths and
Butterflies of Great Britain and Ireland, Vol. 2. There are also four species
of Nepticulidae requiring further study and there is a possibility of finding
certain Scandinavian species not yet recorded from Britain.

The Council’s report was read by the Hon. Secretary and Vice-President,
its approval being proposed and seconded by Messrs. Baker and Jacobs
respectively. The Hon. Treasurer moved the adoption of his report, and
this was seconded by Mr. Bowden. The editor similarly moved the adoption
of his report, and this was seconded by Lt. Col. Emmet. Messrs. Chalmers-
Hunt and Jacobs seconded the approval of the reports of the Curator and
Librarian respectively, which those officers moved; Lt. Col. Emmet proposed
and Mr. J. Heath seconded the acceptance of the Hering Memorial Report.
All the above were passed without opposition.

Under Bye-law 25(b) the meeting was thrown open for queries and
suggestions, and Mr. Bowden asked whether the older slides were being
copied on to smaller size transparencies. The Hon. Secretary explained the
situation and Mr. J. Heath undertook to see whether this task was
practicable at his laboratory.

ANNOUNCEMENTS

The President said that a secretary of field meetings and a recorder, who
would attend to chairs and books at indoor meetings, were needed and
asked for members to volunteer for these positions. He also asked that
the auditors, Messrs. J. L. Messenger and A. G. Stoughton-Harris, should
be re-elected, which was done.

FIELD MEETINGS

SWANAGE — 14th May 1977
Leader — Mr. P. J. BAKER

This meeting was the first in the series in which it was intended to
produce a detailed survey of the Lepidoptera and other insect orders to
be found in the Durlston County Park.

Four members and two guests attended on a sunny though cool day.
A light breeze moderated at dusk and a rapid fall in temperature dis-
couraged any intent to work with lights after dark.

Pieris rapae (L.) and Parage egeria (L.) were the only butterflies noted.
Larvae of Endothenia gentianaeana (Hiibn.) were found in the heads of
the previous year’s teasles (Dipsacus spp.) and Myelois cribrella (Hibn.)
in the dried stems of thistles.

Holm oak and hawthorn were worked for larvae, which proved to be
few in number and small in size. Those which were large enough to permit
identification included: Nola cucullatella (L.), Operophtera brumata (L.),
Euproctis similis (Fuess.) and Allophyes oxyacanthae (L.)—all on haw-
thorn.

The following imagines were flushed or otherwise seen in flight: Pseudo-
swammerdamia combinella (Hiibn.), Ancylis comptana (Froélich), Incurvaria
masculella (D. & S.), Cydia succedana (D. & S.), Elachista rufocinerea
(Haw.) and E. argentella (Clerck).

Professor Owen kindly provided the following Coleoptera records with
the comment that though no rarities are included, several species are quite
local: Harpalus ardosiacus Lut., H. smaragdinus (Duft.), Metabletus trun-

64 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

catellus (L.), Brachinus crepitans (L.), Astenus gracilis (Payk.) f. lyonessius
Joy, Drusilla canaliculata (Fabr.), Timarcha goettingensis (L.), Phyllotreta
diademeta Foudras, Psilothrix viridicoeruleus (Fouc.), Apion fuscirostre
(Fabr.), Otiorrhyncus clavipes (Bonsd.) and Phyllobius oblongus (L.).

A feature of the area was the relative profusion of orchids in flower —
these were: Orchis sphegodes (Mill.), the early spider; O. mascula (L.), the
early purple; O. morio (L.), the green winged, and O. fuchsii (Druce), the
spotted orchid.

BROXBOURNE WOODS, HERTS. — 28th May 1977
Leader — Rev. Davib AGASSIZ

The scheduled leader, Mr. J. Reid, was prevented from attending by a
family bereavement, so a substitute was found at short notice with a
consequent lack of preparation. However, the fine weather did much to
compensate, with cloudless skies and warm sunshine it was about the hottest
day so far in 1977. Six members, with members of their families making
up a party of 12, met at Broxbourne Station and proceeded by car to the
woods near Hoddesdon.

Seven butterfly species were noted on the wing: Erynnis tages (Linn.)
(grizzled skipper), Pieris rapae (Linn.) (small white), P. napi (Linn.) (green-
veined white), Anthocharis cardamines (Linn.) (orange tip), Callophrys rubi
(Linn.) (green hairstreak), Lycaena phlaeas (Linn.) (small copper) and
Lasiommata megera (Linn.) (wall). Other macrolepidoptera seen by day
were Cyclophora albipunctata (Hufn.), Xanthorhoe montanata (D. & S.),
Asthena albulata (Hufn.), Petrophora chlorosata (Scop.), Pseudopanthera
macularia (Linn.) and Callistege mi (Clerck). Among the ‘micros’ were
Ectoedemia argyropeza (Zell.), Incurvaria masculella (D. & S.), Nemato-
pogon swammerdamella (Linn.), Adela reamurella (Linn.), Psyche casta
(Pallas), Esperia sulphurella (Fabr.), Cydia jungiella (Clerck), Epiblema
scutulana (D. & S.), Syndemis musculana (Hiibn.) and Eulia ministrana
(Linn.).

Larvae of the following species were noted and some were subsequently
bred. ‘Macros’: Alsophila aescularia (D. & S.), Anticlea badiata (D. & S.),
A. derivata (D. & S.), Apocheima pilosaria (D. & S.), Bupalus piniaria
(Linn.), Diloba caeruleocephala (Linn.) and Cosmia trapezina (Linn.);
‘micros’: Paraswammerdamia lutarea (Haw.), Coleophora hemerobiella
(Scop.), Epiblema roborana (D. & S.), Croesia bergmanniana (Linn.),
Eurhodope advenella (Zinck.), Stenoptilia pterodactyla (Linn.) and Cnaemi-
dophorus rhododactyla (D. & S.). This last-named species was the most
interesting, but larvae in their characteristic spinnings were scarcely half
grown. It was noted that this species seems to be very selective about the
type of rose it chooses to feed on, but none of the members was able to
name the species with any confidence.

Among the more noteworthy birds in evidence the President recorded
the following: Nightingale, Willow Warbler, Chiffchaff, Cuckoo, Reed
Bunting and Great spotted Woodpecker.

Two members stayed on for night collecting and were joined by another
local member. The night was clear and cold and the catch consequently
disappointing, but one member was rewarded with a specimen of Selenia
lunularia (Hubn.); other species added to the daytime list were: Nemapogon
cloacella (Haw.), Tinea trinotella (Thunb.), Pseudotelphusa scalella (Scop.),
Epiblema cynosbatella (Linn.), Lobesia abscissana (Doubl.), Capua vulgana
(Froél.), Crambus pratella (Linn.), Scoparia ambigualis (Treits.), Epirrhoe
alternata (Mill.), Eupithecia vulgata (Haw.), Cerura vinula (Linn.), Clostera
curtula (Linn.) and Colocasia coryli (Linn.).

CANEWDON SALTMARSH AND HOCKLEY WOOD — 11th June 1977

Leader — Mr. R. W. J. UFFEN

Messrs. Uffen, Hammond, Lindsley and Tomlinson went to Hockley
Station for the start of this meeting, but as the leader was unaware of
the existence of two entrances to this small station, the party split into
two at once. In view of the blustery weather and threatened showers the
first three members sought the protection of Hockley Wood, whilst the
fourth went to the marsh towards Creeksea Ferry Inn, an area visited
at the end of the day by the leader.

Hockley Wood is a fine, mixed deciduous wood, approaching a square
mile in area. The canopy is open in parts, allowing a rich, continuous
ground flora with much grass. Within 200 m. of an entrance to the north-
west of the wood Luzula pilosa (L.) Willd., Chamaenerion angustifolium
(L.) Scop., Stellaria holostea L., Endymion nonscriptus (L.) Garcke, Urtica
dioica L., Rumex sp., Melampyrum pratense L., Melica uniflora Retz., Poa
nemoralis L., Rubus fruticosus agg. and Sarothamnus scoparius (L.)
Wimmer were noted. The oak standards had produced an abundant crop
of seedlings.

Holly, honeysuckle and nut accompanied saplings of the main trees in
the understory, with aspen in the lower, damper south-east. An area of
chestnut here had been cut to leave one standard from each neglected
stump of coppice. An examination of the abundant wood mould in the
crotches of these coppice stumps revealed no obvious signs of insect
inhabitants. The trunks provided a crop of cases of the psychid moth
Taleporia pseudobombycella (Hubn.) and many adult Ectoedemia argenti-
pedella (Zeller) nepticulid moths.

Groups of small Service trees (Sorbus torminalis (L.) Ehrh.) were noted
in the eastern part of the wood. Formica ants abounded in the higher, drier
parts and diverse common insects appeared there between the showers.

The leader drove through Canewdon to end the afternoon at Creeksea
Ferry. On the way marsh vegetation in the bottom of a worked-out gravel
pit looked worth further attention before the active programme of filling
in destroys it. Adjacent was a large area of willow, some shrubs carrying
dense clusters of bud-like galls up to 3 cm. diameter growing from axils
on their twigs.

Near Creeksea Malacosoma castrensis \|arvae were sought where they
have been found in recent years, but none were seen. Much time was spent
searching for insects on Artemisia maritima L. along a causeway and
beside the road, but only one species could be found: a homopteron covered
in white, waxy filaments and feeding mainly on the woody stems at the
base of the plants. Several were maintained in captivity until July, when
they became nomadic and drowned after long periods of immersion in
the water keeping their foodplant fresh. Baby individuals appeared at
this time, but they too failed to settle.

DENNY BOG, NEW FOREST — 18th June 1977

Leaders — Col. D. H. STERLING and Mr. M. J. STERLING

Seven members and three visitors attended; the day was cold and over-
cast. Nothing was on the wing, and the morning was spent working the
heath and bog on the Lyndhurst side of the railway towards Matley.
Perconia strigillaria (Hibn.), the grass wave, Ematurga atomaria (L.), the
heath moth, and Phytometra viridaria (Clerck), the small purple bar, were

66 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

quite easily disturbed from the heather. Chlorissa viridata (L.), the small
grass emerald, was fairly common, but more inclined to sit than be dis-
turbed. All members requiring this species obtained it, including females
for breeding. Micros found included Plutella xylostella (L.), Pleurota
bicostella (Clerck), Cochylis nana (Haworth) and Lampronia fuscatella
(Tengstr6m). A single penultimate instar larva of Dasychira fascelina (L.),
the dark tussock, was found.

The afternoon and early evening were spent working the heath and bog
adjoining both sides of the railway, and some time was devoted to close
searching of the heather. This produced large numbers of newly hatched
larvae of Saturnia pavonia (L.), the Emperor moth, and also some
unhatched egg-batches. Egg-batches of Macrothylacia rubi (L.), the fox
moth, were also very common, and a dead female was found. A further
larva of D. fascelina, this one in its last instar, was also taken, as were
a number of fully grown larvae of Pachycnemia hippocastanaria (Hubn.),
the horse chestnut. Two pupal cases of the large Psychid, Pachythelia
villosella (Ochs.) were found on heather and a number of another, Taleporia
tubulosa (Retzius), on near-by pine-trunks. Three more species of macro-
lepidoptera and some micros were added to the imagines taken in the
morning.

The party left the heath and bog for an area dominated by ancient
woodland oaks, near Denny Lodge, at about 9 p.m. A mixture of eight
mercury-vapour and actinic lamps were set up and an area sugared. Insects
appeared, but only in ones and twos. One large and very persistent visitor
to an actinic lamp was a very large queen hornet, Vespa crabro (L.),
which finally had to be boxed for later release. In all, some 20 different
species of Lepidoptera were identified, including Acronicta alni (L.), the
alder moth, both marbled browns: Drymonia dodonaea (D. & S.) and
ruficornis (Hufn.), Ectropis extensaria (Freyer), the brindled white spot,
Dipterygia scabriuscula (L.), the bird’s wing, and Aethes smeathmanniana
(L.). Some micros are still to be identified.

The weather turned colder about 1.30 a.m. and the meeting ended after
a long day thoroughly enjoyed by all, even if the catches were rather
small.

SANDWICH BAY, KENT — 18th/19th June 1977
Leader — Dr. I. A. WATKINSON

A wet and windy night greeted the eight or nine people who attended
the evening-half of this joint field meeting with the Kent Field Club. In
the few hours before dusk, a considerable effort was put into searching for
larvae, mainly of micros and several of the area’s specialities were recorded,
often in numbers. The larvae of Stenodes alternana (Steph.) were very
common in the unopened flower heads of Centaurea exuding characteristic
piles of frass from their entry holes and a number of these were subse-
quently reared. Larvae of Agonopterix cnicella (Treit.) were as usual very
common on sea holly. Spinnings in sea buckthorn later produced a series
of Spilonota ocellana (D. & S.) whilst the bulk of all the other spinnings
subsequently produced adults of Cnephasia longana (Haw.), C. interjectana
(Haw.) and C. incertana (Treit.). The other larvae of note were a number
of Marasmarcha lunaedactyla (Haw.) well camouflaged on the shoots of
the rest harrow, a few Mesotype virgata (Mufu) feeding at night on bed-
straw and Cochylis atricapitana (Steph.) feeding in the heads of Senecio,
all of which were subsequently reared.

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 67

By kind permission of Princes Golf Club, a convoy of six cars were
allowed to drive across the links in heavy drizzle to the edge of the nature
reserve where we were able to set up some nine mercury vapour and
actinic lights in what little shelter could be found. The light in the lee of the
small pine plantation produced an unexpectedly high catch and boosted the
list of species considerably. Several species typical of the area were recorded
including Sideridis albicolon (Hubn.) Pyrrhia umbra (Hufn.), Cucullia
umbratica (Linn.), Deilephila porcellus (Linn.) and Arctia villa (Ober.) In
addition, a fine fresh Thisanotia chrysonuchella (Scop.) was netted at dusk
by Paul Sokoloff.

The leader left sometime in the early hours to arrive back the next
morning as the last of the night’s collectors were departing after having
stayed on the golf links all night. Five more entomologists gathered in
dryer but still windy conditions and several of the species seen the night
before were gathered. The breeding reports from these activities are still
not complete, but in addition to those previously mentioned, a series of
Gypsonoma sp. were reared from larvae feeding commonly in the terminal
shoots of Populus alba and one Anacampsis populella from leaves of the
same plant. Many of the sea buckthorn plants were being defoliated by
full grown larvae of the brown-tail Euproctis chrysorrhoea (Linn.). Several
Gelechiids were taken by Eric Bradford flying in sheltered spots out of the
breeze but these need confirmation. A number of Coleoptera and other
orders were swept in small numbers by two other members of the society,
of which Martin Newcombe supplied several records which include Platy-
arthrus hoffmannseggi Brandt, a local species of woodlouse recorded from
the nest of an ant believed to be Lasius flavus. Amongst the Orthoptera
were taken Chorthippus parallelus (Zett.), Conocephalus discolor Thunb.
and Tettigonia virridissima Linn. A specimen of Ectobius panzeri Steph.,
one of our native cockroaches, was tentatively identified from a nymph
taken under marram grass. The Hemiptera-Heteroptera were represented
by Anthocoris nemorum Linn., Kleidocerys resedae (Panz.), Liocoris. tripus-
tulatus (Fab.), Notostira elongata (Geoff.), Pithanus maerkeli (H.-S.), Podops
inuncta (Fab.) and Scolopostethus affinis (Schill.). A balanced afternoon
was rounded off by finding a young leveret crouching in long grass by the
Toad.

On the way home, the leader stopped near Ashford to check for larvae
of Acleris sheperdana (Steph.) in Spiraea shoots. Several spinnings were
taken and from these a very good series was later reared. Altogether a
most enjoyable weekend.

NORTHWARD HILL N.N.R., KENT — 25th June 1977
Leader — Mr. M. J. NEWCOMBE

Apart from the leader, the only other member to attend this meeting
was the curator, Mr. E. Bradford, despite weather conditions which proved
almost ideal for collecting. Whilst waiting at the church for the arrival
of other members, a look was taken at the churchyard, which contained
a number of lichen-encrusted memorial stones, from one of which a rather
melanic specimen of the dipteron Tabanus bromius L. was taken.

The reserve was rich in species, and Mr. Bradford collected a number
of new records for this site, of which Alabonia geoffrella (L.), Scoparia
ambigualis (Treits.), and Anthophila fabriciana (L.) were especially abun-
dant, the latter especially so amongst stinging nettle. The most impressive
find of the day was that of Ectoedemia subbimaculella (Haw.), several
thousand of these tiny moths being seen resting on the trunks of oak
trees in a particularly sheltered part of the wood. A single larva of

68 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

Quercusia quercus (L.) was taken from beneath a log. Other species
recorded included Hepialus lupulinus (L.), Nemophora degeerella (L.),
Tinea semifulvella (Haw.), Argyresthia curvella (L.), Epinotia trimaculana
(Don.), Orthotaenia undulana (D. & S.), Hedya pruniana (Hiibn.), Pseudar-
gyrotoza conwagana (F.), Chrysoteuchia culmella culmella (L.), Scoparia
arundinata (Thunb.), Udea olivalis (D. & S.), Camptogramma bilineata
bilineata (L.), and Hypena proboscidalis (L.).

The leader examined the heteropterous fauna and recorded the rather
local bug Legnotus limbosus (Geoff.) which was extremely abundant
amongst moss and litter covering a small heap of discarded tarmacadam.
On stinging nettles Eysarcoris fabricii Kirk., Heterogaster urticae (F.),
Scolopstethus affinis (Schill.), S$. grandis Horv., Himacerus mirmicoides
Costa, Anthocoris nemorum (L.), Orius niger (Wolff), Psallus varians (H.-S.),
Heterotoma merioptera (Scop.), Liocoris tripustulatus (F.), and Calocoris
norvegicus (L.), were recorded. The oak fauna was equally rich, with bugs
such as the shoot-sucking Calocoris quadripunctatus Villers abundant on
solitary oaks, whilst Phylus melanocephalus (L.), Cyllecoris histrionicus
(L.), and a single late adult of Dryophilocoris flavoquadrimaculatus (Deg.),
were found in oak stands. Other bugs noted were Podops inuncta (F.),
Kleidocerys resedae (Panz.), Drymus sylvaticus (L.), Cymus melanocephalus
Fieb., Tingis ampliata (H.-S.) and T. cardui (L.) (both on spear thistle,
Cirsium vulgare Ten.), Nabis rugosus (L.), Deraeocoris scutellaris (F.),
Plagiognathus arbustorum (F.), Dicyphus epilobii Reut. (unusually scarce
on the willowherb, Epilobium hirsutum L.), Phytocoris dimidiatus Kirschb.,
Capsus ater (L.), Notostira elongata (Geoff.), and Leptopterna dolobrata
(ie):

Finally, the assistance of the warden, Mr. R. E. Scott, in so kindly
allowing us to visit all parts of the reserve, must be most gratefully

acknowledged.
CURRENT LITERATURE
BOOKS
The British Butterflies: their origin and establishment by R. L. H. Dennis.

E. W. Classey Ltd., 1977, 318 pp. Price £10.00.

Pioneer studies on this subject were made by E. B. Ford and B. P.
Beirne more than thirty years ago, and up-dating and re-examination are
long overdue. Mr. Dennis devotes the first section of his book to a compre-
hensive survey of recent research into the glacial and post-glacial geography,
climate, flora and remains of coleoptera in the British Isles and northern
Europe, both on a national and regional basis, in order to set the framework
within which he believes that the present species of butterflies arrived and
established continuous existence here. The evidence which he uses is,
though detailed, still very incomplete, and much of it is uncertain or
contradictory on the vital point of dating; and his handling of it is marred
by excessive use of technical terminology which is not well explained and
is hard to follow. His conclusions, however, are in startling contrast to
those of the earlier writers. Though he does not deny that butterflies
may have existed here earlier, he states categorically that none could have
survived the maximum of the last main glaciation, either on the present
land surface or, as Ford and Beirne suggested, on ice-free land since
submerged as sea levels rose with the melting of the ice sheets. This
maximum, which he calls Devensian in the British Isles, Weichselian in
Europe, he dates to about 15,000 to 18,000 years ago. Indeed, he goes
further, arguing that one at least of the cold periods (‘Zone III’) which
followed the initial warming of the climate and withdrawal of the ice

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 69

would have made the establishment of all but a handful of our present
species improbable until the pre-Boreal period about 12,000 years ago, after
which the climate became for a time better than at present. If these
conclusions are correct, they have much biological significance, since they
allow vastly less time than previously for the development of British and
Irish subspecies and local races, which is dealt with in Section C of the
book. But the conclusions are not beyond question. Mr. Dennis himself
finds difficulty in discovering for so recent a date a land connection with
Ireland, which is necessary to explain the presence there today of nearly
half of the British species. Further, he endorses both in text and map the
view that in England Devensian ice sheets did not extend south-east of
the Humber/Severn line; yet his contention that the country between it
and the present shores of the North Sea and English Channel was clima-
tically uninhabitable for butterflies seems to overlook the fact that some
twenty species on the British list now breed in Fenno-Scandia within the
Arctic Circle.

Section B deals competently with the distribution of species within the
period of record, discussing both their discontinuities and apparent changes
in recent times; and there is interesting discussion of the forces governing
the adaptation of several species to different or changing environments.
Subspecies and local races are treated in Section C, subject always to the
argument that their existence or non-existence gives little or no clue to
the dates of which species became established in Britain. The long last
Section suggests a new arrival sequence, which is compared in tabular
form with the sequences provided by Beirne and Ford, from which it differs
greatly. In building up his own argument the author gives much weight
to the large oscillations of climate, both as regards temperature and
humidity and sunshine, since the maximum of the Devensian ice age. His
picture is one of a general arrival and extensive spread of most species
during the warm pre-Boreal and Boreal periods, followed by contractions
of range in the British mainland and probably by extinctions in Ireland,
outlying islands, and even Britain itself during one or other of the cooler
or damper periods which followed, or resulting from man-made changes
in environment. Once considerable barriers of sea had appeared between
the British Isles themselves and between Britain and Europe, further
colonisation or recolonisation became almost impossible for any butterfly
species except those now recognised as migratory.

This book is full of interesting material and stimulating interpretation
of it. Much of both is, however. more uncertain and controversial than
the author seems to recognise. He could with advantage have written it in
simpler language and with more thought for presentation to the many
non-technical entomologists who may try to read it. The bibliography is
excellent, and the printing is good and accurate, although more conspicuous
and larger type for the numbering and captions of the many figures and
tables would have been an improvement.

Insect Photography for the Amateur by P. E. Lindsley. Amateur Ento-
mologists’ Society.

In the pursuit of insects, both as trophies and as objects of research,
the camera is already an established rival of the net. Mr. Lindsley takes
us right through the whole subject of insect photography, including basic
principles, choice of camera and other equipment and the numerous
accessories designed for close-up work. Throughout he does not simply

70 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

lay down the law, but explains why this accessory is useful in photographing
insects and that one can be dispensed with. Lighting, with the emphasis
on electronic flash, is treated in the same way.

In his chapter 5, ‘Getting Down To It’, he makes it clear that he is
writing from experience, and the first paragraph ends with the words: ‘I
cannot emphasise too strongly that the key to success is practice and
experimentation, coupled, particularly in early days, with keeping meticulous
details of every picture you take.’ Good advice indeed. He distinguishes
between the ‘record shot’, usually taken indoors to show the subject’s
visible characteristics, and the ‘natural history shot’ which is taken in the
field to show some aspect of its behaviour. Each of them is as important
and valid a branch of insect photography as the other, and useful advice
is given on both.

The final section on photographing mounted or set specimens is contri-
buted by Mr. D. Carter and completes a practical and valuable summary
of the subject.

The Dragonflies of Great Britain and Ireland by C. O. Hammond. Curwen

IBEESSn Lou.

The British list of Odonata numbers no more than 44, and all are
relatively large insects. Nevertheless, identification of the species is by no
means easy. The separation characters, largely of pattern and colour, are
difficult to describe verbally, often variable and frequently as distinct
between conspecific males and females as between the same sexes of allied
species. An added complication is the change in coloration that often takes
place as newly eclosed or ‘teneral’ specimens grow to imaginal maturity.

By means of keys and descriptions carefully correlated, item by item,
with numbered drawings and diagrams, all in colour, this beautifully
produced and illustrated book provides, for the first time, a means of
confidently determining specimens of dragonflies and damselflies in the
British fauna. Mr. Hammond, who is both author and artist, deserves
congratulations and thanks from us all, and his book will do much to
stimulate interest in our native Odonata.

The well known keys and drawings by the late A. E. Gardner, illustrating
the aquatic early stages, are incorporated as a final chapter. It is a matter
for deep regret that Mr. Gardner’s untimely death prevented him from
contributing an expanded version of this section of the book. Distribution
maps from John Heath of Monk’s Wood provide a valuable appendix.

Many beginners in entomology are dismayed and put off by the standard
‘key’, in which one, or at the most two, characters are selected to serve
for separation and are supported by quite inadequate illustrations or none
at all. Books modelled on Hammond’s ‘Dragonflies’ are laborious to produce
and expensive to publish, but surely they are worth while. Let us hope
that some other suitable categories of British insects will before long
receive similar treatment.

Naamlijst van de Nederlandse Lepidoptera by B. J. Lempke. Koninklijke
Nederlandse Natuurhistorische Vereningung, Amsterdam, 1976, 99 pp.
No price stated.

This list complements the ‘Check List of British Insects’ as revised by

Bradley, Fletcher and Whalley in 1972. Like that, it lists all taxa at sub-

specific level, and it follows it closely in arrangement and nomenclature.

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 71

Changes to take account of later published work are most evident in the
Nepticulidae, which have been recast, and in the Oecophoridae, which have
been split into three sub-families with revision of generic names. In the
Papilionoidea no less than fifteen more sub-families have been introduced,
without apparent profit to anyone except the printer. It is interesting that
in the Noctuidae Actinotia polyodon (Clerck) has returned to Boursin’s
place for it among the Amphipyrinae, while another taxonomic lost soul,
Axilia putris (Linnaeus), is retained among the Noctuinae at the price of
a change in generic spelling. The foreword, introduction, and commentary
on special points in families are in Dutch, but there is a one-page epilogue
in English. This reviewer regrets that numbering of the taxa has not been
used for the text and index: this would be of much help in finding them
quickly and in references.

The two lists together provide an easy means of comparing the lepidop-
tera of the two countries. The epilogue tells us that, after excluding extinct,
doubtful, and casual species, which are marked by symbols, the British
list counts 2,247, the Dutch 2,109. However, much of the British superiority
comes from the larger number counted as separate sub-species. Thus in the
Hesperoidea and Papilionoidea the British list counts 100 taxa (? not all
worthily), of which only 66 represent separate species, while the Dutch
count is 86, of which all but one are specific: so by the usual standard
the Netherlands wins easily after all!

The Naamlijst is very clearly printed on excellent paper, and it has an
attractive colour picture of Arctia caja (Linnaeus) on its cover. It deserves
a place in all entomological libraries.

Die Schillerfalter by Ekkehard Friederich. Die Neue Brehmbiicherei,
A. Ziemsen— Wittenberg Lutherstadt, 1977, 112 pp., 2 colour plates,
64 figs. Price 12 DM.

This attractively presented paper-back summarises what has _ been
published on the three Apatura species iris (L.) (our Purple Emperor),
ilia (D. & S.), and metis Frr.), of which only the first inhabits Britain, and
the third is probably known to our readers, if at all, from the British
Museum’s fine material, or the pages of Seitz, Vol. 1. It is a group of
perennial popular appeal.

The morphology of all stages is illustrated and described, the figures
including electron-scanning microphotographs of the eggs and the wing
scaling. However, the details for A. metis refer mainly to the Far Eastern
form substituta Butler studied by Takakura, rather than the East European
metis metis of which, apart from good black and white photographs of
Hungarian adults, there is comparatively little. On the vexed question of
its specific distinctness from ilia, the author, after a literary-historical
review, concludes that this has been established, thereby differing from
Niculescu 1977, reviewed in our Vol. 10 (3/4): 125. It may here be added
that the British Museum’s arrangement of the forms also presents metis
as a distinct species. A black and white figure shows the underside
differences between A. metis and ilia; these would appear to be greater than
the male genitalia of the two forms. The female genitalia are not illustrated.

Details and photographs of the eggs, larvae their foodplants and habitats,
in Europe and Japan, are reproduced; not unexpectedly, observations from
intermediate Asiatic localities are lacking. Heslop’s well-known notes are
quoted at some length in the section on the habits of A. iris. A detailed
section on breeding, hand-pairing and hybridisation appears to contain the

ap? PROC. BRIT. ENT. NAT. HIST. SOC., 1978

results of considerable original work by the author, whose other personal
contribution of interest concerns A. iris ab. iole D. & S., which he bred
and subjected to temperature experiments; these tended to disprove an
earlier supposition that this aberration was the consequence of unusual
temperatures affecting the pupa. The numbering of the hindwing veins in
fig. 24 is decidedly unorthodox; after counting the two anals as 1 & 2, the
author arrives at a figure 9 for the costal!

On the whole we warmly recommend this most useful guide and summary
to all students of Rhopalocera who can read and understand German.

E.P.W.

A Guide to the Butterflies of Central and Southern Africa by E. Pinhey
and I. Loe. 1977, Causton, London and Eastleigh. Long 8vo., 106 pp.
with 29 coloured plates in watercolours depicting 135 species, together
with a further 64 species in colour photographs taken in the field and
numerous line drawings. Price £4.95.

This is an excellent book and should prove most popular with those
interested in the more common and spectacular butterflies of this area of
Africa. The 280 life-size watercolour illustrations of adults are truly out-
standing in their detail and accuracy. The 144 colour photographs of adults
and sometimes larvae are extremely interesting subjects and help to convey
the charm of these insects in their natural surroundings.

There is a brief introduction and chapters on features of a butterfly,
life cycle, variations in form and colour, warning coloration and mimicry,
habits, collecting, preservation, rearing, names, families and some of their
characteristics, a glossary, entomological dealers, African reference collec-
tions, further reading and an index of scientific and common names. The
various families are dealt with in their systematic order and each has
a brief introduction with colour photographs and line drawings to illustrate
various points. These are followed by the excellent life-study photographs
arranged six to a page. The captions of these are placed in the page gutter
and give brief details of habitat and distribution where these are not given
in the main text. If these are mentioned in the text then a number is given
which refers to the species, each of which is numbered consecutively
throughout. The figures on the plates are also given these numbers so that
cross references are easily found. It would have helped if reference numbers
could have been given to illustrate various points in the introductory
chapters and in the captions of the figures immediately associated with
them.

As is pointed out by the authors, the book is primarily intended for the
beginner who should be able to identify his or her specimens quite easily
from the excellent illustrations and at the same time to learn a little about
the insects themselves from the necessarily brief text.

In the reviewer’s opinion it would have been better if the scientific
names were italicised throughout rather than use roman capitals in the
captions of the plates and photographs. On page 13 the names Precis and
Colotis should be in italics and also bohemani on page 24 line 8. In the
section dealing with names no mention is made of author’s names and the
significance of the brackets sometimes used with them, though the names
themselves are used in the main text. It would have helped had the author’s
name been separated from the common name by an extra space, for one is
confronted with such strange combinations as Neave Marshall’s Highflier
(69), Dixey Paradox (87), Trimen Bowker’s Hairstreak (68) and many
others. Apart from these few minor criticisms, the authors and publishers
are to be congratulated on a well produced book which is well worth its
price for the illustrations alone.

Collecting and Studying Dragonflies (Odonata) by David Keen. A.E.S.

Leaflet No. 12. Revised Edition 1977. £1.60.

The title suggests an essentially practical approach to the subject which
David Keen has tackled admirably, presenting a wealth of information in
the compass of 24 pages.

Sections deal with habitats, life-history, collecting equipment, rearing,
killing, pinning and setting and arrangement of the collection; amply
helped by useful illustrations and followed up by suggestions for further
studies.

In dealing with the nymphs the author is careful to emphasise the
importance of replacing in the water unneeded pond weed and debris and
to leave the locality as it was found, and Appendix I gives a code of insect
collecting. He rightly suggests ethyl acetate as the most suitable killing
agent for adults but this is very difficult to obtain from local chemists.
However, a similar product under the name of ‘Killing Fluid’ can be
purchased at the A.E.S. Exhibition annually. Ammonia should never be
used as this quickly removes the powder-blue pruinescence from adult
males of Libellula and Lestes species.

Limitation of space has precluded the inclusion of classification, though
Appendix II gives a loose check-list for labelling the collection. There is a
useful bibliography which will enable the student to continue the study
after he has made himself familiar with this very readable booklet.

OUR CONTEMPORARIES
Lepidoptera, 3 (2/3), 1976/77
The Lepidoptera Society of Copenhagen has for several years been
producing a new series under this title of high quality, with plentiful
illustrations, particularly good of larvae, on good paper and with subject
matter of interest to British lepidopterists. The latter will find the text
entirely Danish and the final summaries in English, present in most articles,
very short. The illustrations usually make up for those disadvantages and
our readers are therefore recommended to watch out for this magazine for
helpful material. In the current number we single out for mention a fine
colour plate of a remarkable aberration of Mesoacidalia charlotta (L.), a
report by J. E. Jeines on the discovery of Eriopygodes discalis (F.) in
Denmark, in the shape of a single male at Charlottenrud, ‘probably a
migrant from Sweden’, and an article by Michael Fibiger on the group of
grey Cucullia species.

Applied Entomology and Zoology, 12 (2), 1977 (Tokyo)

Sometimes a journal of applied entomology has matter of general ento-
mological interest, and in such cases we single out for mention here the
articles; in the present case, this well produced review, produced by the
Japanese Society of App. Ent. and Z., Tokyo, entirely in English despite
its Japanese origin, contains eleven longer articles of which we select one,
and eight shorter articles, of which we mention another. The longer is by
K. Nakamura and K. Kawasaki and is entitled ‘The active space of the
Spodoptera litura (F.) sex pheromone’ (pp. 162-177). This gives account of
experiments involving the release and recapture at pheromone traps of
moths of this species, to determine the range of effectiveness of the scent
released by the living female or the synthetic pheromone. The maximum
range down-wind for one virgin female was estimated at about 80 metres
for a wind velocity of 0.50 m./sec. This distance decreased with an
increase in wind velocity but decreased greatly with a decrease in wind
velocity. The reason for the decreased range at low wind velocity was said

74 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

to be deposition of the pheromone. In a windless greenhouse, the active
space was limited to a small area close to the attractant. Quite apart from
its relevance to recent controversies on the mode of assembling males
of lepidoptera, which the authors do not comment on, they point out that
this characteristic of pheromone diffusion, dependence on wind-velocity,
will seriously affect the application of pheromone as a sampling tool of
insect population and as a method of insect pest control. Secondly, and
more briefly, Harushisa Wago (pp. 203-5), describes ‘Mating behaviour
of Zizeeria maha argia in connection with visual stimuli from Zizina otis’.
These are two allopatric but rather similar Japanese blues, differing mainly
in upperside colouring. The optical properties of the wing undersurface
of both species are shown by the experiment to be similar and probably to
play an indispensable role in the male’s attraction and its attempt to
copulate. In figure 1 the author shows a photograph of an argia male
attempting to copulate with the undersurface of ‘a dummy of otis’ male.
Dummies of pinned specimens of both sexes of otis placed on a leaf were
used in these experiments, which compared the number of argia males
approaching argia in similar conditions. The author states that mating in
these butterflies occurs most frequently when males respond to motionless
individuals with the undersurface exposed. The author certainly seems to
have discovered a hitherto unsuspected factor in the courtship of blue
butterflies, which ought to be possible for experimentalists in many parts
of the world to confirm, or to disprove, with their own local species.

A LEPIDOPTERIST’S HANDBOOK

The Amateur Entomologist’s Society is pleased to announce the publication
of its latest Handbook, written by Richard Dickson. It is intended as a
‘vade mecum’ for both beginners and initiated lepidopterists and deals with
all aspects of the subject in a series of eleven chapters and four appendices.
There are 34 line illustrations and 13 photographs to augment the text
and the binding has been sewn to meet constant use.

It is a practical book on the various facets of breeding, collecting, storing,
conservation and photography of lepidoptera and should appeal to most
lepidopterists. Although the various techniques relate to the British fauna,
most are valid for lepidopterists anywhere.

The price is £3.00 plus postage and is available from A.E.S. Publication
Agent, 137 Gleneldon Road, London, SW16 2BQ. (An invoice will be sent
with orders, including postage.)

PRESIDENTIAL ADDRESS
(Read on 26th January 1978 by Ratpu Tupss, O.B.E., F.R.E.S.)

I. TopicaAL REMARKS

From the Report of the Council, which has just been read, you will
know that the Society is still flourishing. The membership continues to
increase and there are now about 700 members. Sixty-one new members
elected during 1977 is a most encouraging sign. There is no doubt that a
further increase in membership would add to the influence of the Society,
increase the scope of its debate and make financially possible more illus-
trations in our already excellent Proceedings and Transactions. 1 would,
therefore, ask all members to encourage any keen entomologist whom
they know and who is not already a member to join at once.

There is one action taken by your Council this year to which I would
like specially to draw your attention —and that is the decision to publish
as soon as possible a new and completely revised edition of L. T. Ford’s
most valuable book A Guide to the Smaller British Lepidoptera. It is
nearly thirty years since this Society first published this book and during
those years there has been a great deal of work done on the ‘micros’ —
work partly inspired by the book itself. The text will now be brought
competely up-to-date with much new information and the very distinguished
team of authors, under the expert leadership of Col. A. M. Emmet, have
already made very good progress. I would like to thank all who are
co-operating in this work. We have obtained a very reasonable price for
printing and I hope publication will be achieved this summer. I feel that
this Society, which already has pre-eminence in field entomology, has a
special responsibility to share the knowledge obtained in the field and
thereby make its own contribution to science.

Our Annual Exhibition is another form of communication by which
we share our knowledge. This year there was a record attendance and
the standard of exhibits was remarkably high.

Links with other societies are also valuable. In 1977 the Lancashire
and Cheshire Entomological Society celebrated their Centenary. I had the
honour and pleasure of attending their Centenary Exhibition and Con-
versazione at the Adelphi Hotel in Liverpool at the invitation of their
President, Mr. R. C. R. Crewdson. We were also glad to welcome Mr.
W. A. Watson, their Vice-President, at our Annual Dinner at Imperial
College, which again was well attended.

It is now my sad duty to remember with you those of our members
who have died during the past year.

Professor H. E. Hinton, F.R.S. died on 2nd August 1977 at the age
of 64. He joined our Society in 1945 and was our President in 1972. Born
in Mexico in 1912, he went to university in Berkeley, California. Then
in 1934 he came to England and took a Ph.D. under A. D. Imms at
Cambridge. In 1939 he was appointed a taxonomist in the Department
of Entomology at the British Museum (Natural History). Ten years later
he joined the staff at the Zoology Department of Bristol University, where
he continued to work, becoming Head of the Department in 1970. He
was elected to the Royal Society in 1961 and President of the Royal
Entomological Society 1969-70. He always worked immensely hard, con-
tinuously publishing the results of his research. It was typical of him that,
when he learnt he had only a short time to live, he worked harder than
ever, completing his long-planned three volume work on the biology of
insect eggs just before he died.

H. C. Huggins died at Westcliff-on-Sea, Essex, on 14th April 1977, in his
86th year. Before retirement he had worked with Westminster Bank,
becoming a branch manager. At the time of his death, he had been a
member of the Society for forty-three years. He began collecting when
a boy of eight and was helped in his early years by A. B. Farn, who
was a relative. During his long entolomogical career he encountered such
knowledgeable entomologists as J. W. Tutt, Charles Fenn and Richard
South. He was primarily a lepidopterist, concentrating after 1922 largely
on micros, at a time when the knowledge of these was much more limited
than it is today. He had a special interest in the Pyralidae and Tortricidae.
At one period, however, he took a serious interest in British land and
freshwater mollusca, publishing in 1918 a significant paper on ‘The
Lymnaeae of the Alpine Lakes of the Glengarriff District, West Cork’.
Indeed Ireland always had a great appeal for him and he made collecting
trips there nearly every year. He was a considerable writer and made
regular contributions to the entomological journals, many of them on new
subspecies and aberrations. His fine collection has been given to the
British Museum (Natural History).

D. W. H. ffennell died in August at the age of 56, beside the moth-trap
in his garden. He was educated at Eton College, where he was a fellow
pupil with E. C. Pelham-Clinton, and at Cambridge University. He joined
the Society in 1940. He inherited a fine country house and a large garden,
part of which he converted into a market garden. Although he had a
special interest in Microlepidoptera and Neuroptera, his interests were
wide and there are few people who have had a more comprehensive
knowledge of the Lepidoptera. He recorded approximately 1,000 species
from his estate, Martyr Worthy Place, near Winchester. He added to the
British List, Phyllonorycter dubitella (Herrich-Schaffer) (Lep.: Gracil-
lariidae) and Lampronia flavimitrella Hiibner (Lep.: Incurvariidae). He
played a considerable part in the preparation of Barry Goater’s ‘Butterflies
and Moths of Hampshire’, especially for the Microlepidoptera, and was
engaged in the Oecophoridae for the next volume of the ‘Moths and
Butterflies of Great Britain and Ireland’ and had done valuable preliminary

Clifford Crauford died on 23rd March 1977, at the age of 94. He
joined the Society in 1918 and was made a Special Life Member in 1971.
He was educated at Clayesmore School and Edinburgh Academy. His
parents lived in British East Africa, where his father was Consul-General,
so that many of his school holidays were spent at school where a master
started his life-long interest in entomology. In the early ‘twenties’, when
he was living at East Molesey, much of his collecting was done in Surrey.
However, he moved to Bishops Stortford in 1925 and ten years later was
a founder member of the Bishops Stortford and District Natural History
Society. His principal interest was in the moths, keeping constantly a trap
in his garden and compiling full statistical records. He was a friendly
and helpful person and he held an oft-stated opinion that a//l entomologists
are nice people!

Dr. D. Kyle, O.B.E., died in 1976. He lived in Brecon, Powys, where
he was a distinguished doctor, receiving his O.B.E. in 1972. He specialised
in Odonata.

Finally, before coming to the subject of my address, I would like to
express my thanks to the officers and members of Council who have not
only worked so hard for the Society but also given me so much support
and help during my term of office. Mr. G. Prior, your next President, has
as Secretary given me invaluable assistance, and is one of those who come
frequently to these premises on non-meeting days and work in the base-
ment. There you will have seen how much better laid out is the room
housing our collections, largely the work of our dedicated curator, Mr.
Eric Bradford, and his assistants. The library is also better arranged and
Dr. Allen is now working hard on this. Our Editor, Mr. E. P. Wiltshire,
has produced excellent Proceedings and Transactions and has achieved
the very difficult task of bringing them out on time, for which he must
be congratulated. Our Treasurer, Mr. R. F. Bretherton, has as usual kept
our finances in good shape. The Society is also much indebted to Mr.
G. R. Else and Mr. E. H. Wild for arranging the programmes for the
Indoor Meetings and Field Meetings respectively. I should also like to
thank Mr. R. Dyke for his excellent drawing for the Christmas Card. All
these and other members give their time and expertise. There is something
about our Society which inspires not only loyalty, but real affection.

I now come to the second part of my address, the title of which is: —

THE BREEDING OF BUTTERFLIES WITH SPECIAL REFERENCE TO THE
GENETICS OF ABERRATIONAL FORMS
(with Plates VI & VII and two text figures)

1. Introduction

For thirty years I have been breeding butterflies and have bred from
the egg most of the indigenous species. It is only by breeding that you
really get to know an insect. Although starting with typical insects, my
interest soon turned to aberrations. I am an inquisitive naturalist: I am
not satisfied with just having a set aberration killed on capture in the
wild. I want to know how it came to be different. To kill an aberration
without getting eggs or a pairing is killing the Golden Goose. I do not
collect butterflies, I collect genes. Then if you have friends with similar
interests you can exchange genes. For example, I am indebted to Mr. R.
Revels for exchanging genetic material with me—sometimes an imago
sent by post on the evening of capture, sometimes eggs. Of course, it is a
gamble, the insect may ruin itself without laying eggs — but the prize, both
in terms of knowledge and in bred specimens, is worth the risk. I shall be
showing you later slides of many of the aberrations I have bred.

2. Breeding techniques

Although many members are themselves experienced breeders of lepi-
doptera, I feel it might be helpful if I give a brief description of the
methods I use. Almost every person has a slightly different technique.
As I need to breed several generations, I try to simulate fairly natural
conditions. I do not use continuous breeding techniques with high intensity
lighting for 24 hours a day to overcome diapause, as this frequently
leads to failure to get pairings due to imagines emerging in the winter
months and the whole strain may be lost. I would advise every breeder
always to get an F2 generation to see what this reveals. It is very wasteful
of time only to breed one generation.

78 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

(a) The horticultural problem

Let us begin by considering the foodplant — no food, no butterflies! 1
try to pot up the foodplant well in advance, preferably in February or
March. Some foodplants such as honeysuckle simply will not move in the
summer months.

It is not easy to keep the plants healthy when there is fine netting
over the plant as this reduces the enlivening movement of air. If the plant
leaves are kept too dry, aphids will be a serious menace. I find it, therefore,
useful to spray the leaves regularly. If the plant is too damp in the winter,
mould is likely to grow. This especially applies to Poa annua, a plant also
very susceptible to aphids, so, if you are breeding the ‘grass feeders’ I
would strongly recommend the use of a grass less liable to mould, such
as the creeping lawn grass (Agrostis species). Another horticultural problem
occurs with Hippocrepis comosa, which is sometimes attacked by ‘powdery
mildew’ in mid-summer. This is disastrous as the only treatment is a
poisonous spray. I think this disease is again encouraged by keeping the
leaves too dry.

(b) Humidity

Keeping the correct degree of humidity is indeed the key to success in
the overwintering of larvae. After thirty years I still feel I do not know
enough about this. I keep a light roof, covered with transparent plastic,
over the pots containing the hibernating larvae. This frame used to have
sides partially covered with plastic sheet, but I have now changed to
completely open sides—open, that is to say, apart from fishing net
provided to keep out cats and squirrels! The intent is to keep the larvae
fully exposed to natural weather conditions, while not allowing rain to
fall directly on the pots. Some entomologists are brave enough to leave
their pots completely exposed to every rainstorm and they have consider-
able success. One must not think in anthropomorphic terms and it is
better for the larvae to be too wet than too dry. In early years I lost a
whole brood of Boloria euphrosyne (L.) as the little larvae desiccated.
Humidity is not only important for larvae: those species which pupate
just below the earth’s surface, such as Hipparchia semele (Hubner), also
need the soil to be kept moist if losses are to be avoided. I also spray
my over-wintering eggs once a week.

(c) Predators

However, it is not sufficient to have the correct environmental conditions,
for constantly waiting for their opportunity are the predators. The most
devastating are the pale coloured carnivorous slugs, spiders and earwigs
(Dermaptera). I keep all my pots on trestle tables to keep them further
away from pests, but, alas, the slugs are introduced with the soil when
the foodplant is dug up and slugs lay 300-500 eggs in batches under stones,
in moss, etc. It is important therefore to put slug pellets around the edge
of the pot. I am not aware that these do any damage to the larvae but,
to be on the safe side, I place them as far from the plant as possible.

As for spiders, I must be one of the finest spider breeders in the
country! They also come in with the foodplant. I immerse the plants in
water at the time of planting to drive the spiders out, but this seems a
totally inadequate precaution. Regular inspection seems the only answer.
The same applies to earwigs.

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 79
3. Keeping records

I always keep very detailed records. These fall into two categories —
an analysis of the forms of the imagines for genetical purposes and details
of every event in the insect’s life history. It is interesting to note, for
example, that Aphantopus hyperantus (L.) usually emerge between 7.00
and 8.00 a.m., whereas Lysandra coridon (Poda) emerge between 10.30
and 11.30 a.m. Exact sizes of hibernating larvae will be useful in future
breeding and so on.

4. The Genetics of Aberrations

Few things in Nature are entirely clear-cut — Nature is four-dimensional.
Thus it is difficult to give a clear demarcation line between an aberration,
a variety or an example of polymorphism. However, each of these devia-
tions from the normal form have one thing in common—they are
genetically produced. (I am excluding here those forms produced by drastic
temperature change.) For breeding purposes, it is useful to consider the
varying forms of butterflies under five categories: —

(a) The distinct and definitive aberration —e.g. ab. syngrapha Kef. of
L. coridon. This aberration is quite clear-cut; the butterfly is either
ab. syngrapha or it is not. There are no grades.

(b) Aberrations which graduate from one form to another, e.g. ab.
lanceolata Shipp of A. hyperantus —in which there is every grada-
tion from the slightly elongated dot to the extreme form with bold
streaks across the wing.

(c) Inconstant characters found in various populations which are due
to genes regularly present in the gene pool, e.g. the variation in the
extent of blue colour in female Polyommatus icarus Rottemburg.

(d) Dimorphic species such as Argynnis paphia (L.) which has the two
forms of the female — the typical and var. valesina Esp., or Coleas
crocea Fourcroy which has the var. helice Hiibn. form of the
female.

(e) Distinct local races such as the very striking form of Maniola jurtina
(L.) found on the Isles of Scilly.

In addition to these five categories, mention should be made of those
aberrations produced by drastic temperature change. Particularly striking
forms have been produced artificially in this way with some of the
Nymphalidae, especially Aglais urticae (L.) and Polygonia c-album (L.),
in which the pattern is suffused and there is a considerable increase in the
black areas. Some suffusion of the black markings in Argynnis paphia and
the white markings in Vanessa atalanta have also been thus artificially
induced. I have not tried this technique myself, but I understand that the
pupa is put 5-6 hours after pupation in a refrigerator at a temperature
of approximately 25°F. for between 6 and 12 hours. It is not certain
whether temperature alone creates these aberrations or whether certain
abnormal genes also have to be present.

I will now turn from a general study of the breeding of butterfly
aberrations to the consideration of individual species, illustrating the
argument with slides.

Every aberration which I am showing was either bred or caught by
myself. I would like to express my gratitude to R. Revels for taking the
photographs for me.

I will consider a number of species selected for their particular interest
in variation in the order which proceeds from the most specialised to the

80 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

most primitive, starting with the Satyridae. The names used are those
given in the new edition of Kloet (G. S.) and Hincks (W. D.) ‘A Check
List of British Insects’ (1972).

Lasiommata megera (L.)

This species is subject to great enlargement of the ‘eye’ spot ab.
anticrassipuncta Lempke. To my shame, I killed the fine female which I
took at Beer, Devon in 1964. In the light of my experience in breeding
other Satyridae, 1 think that it is likely that this form is caused by a
single gene with modifying resistance from other genes and is therefore
likely to breed with a gradation in the size of ‘eye’ spot.

Erebia aethiops (Esper). Bred female. Ova 13.8.62, imago 17.7.63

This specimen has unusually large spots and brilliant markings. There
are two distinct colour forms of the female underside hindwings: —
(a) Ochre banded — which seems to constitute the form ochracea Tutt.
(b) Silver banded —as specimen taken at Morar, 12.8.6].

Further work is required to find out the relationship of the two colour
bands.

Incidentally, there is no need to find Blue Moor Grass (Molinia coerulea)
on which to feed the larvae, which feed happily on Poa annua.

This seems to be one of the few butterflies that needs neither foodplant
nor sunshine to encourage it to lay eggs. On 12th August 1962, four
females were brought by car from Aviemore. On arrival in Surrey it was
found that 75 eggs had been laid in the tins during the journey.

Melanargia galathea (L.)

In July 1974, I was generously given by Robert Craske six living imagines
(four male and two female) of an aberration which consists of a consider-
able enlargement of the forewing costal blotch. This new and very local
aberration has been found since 1970 in two restricted localities in Sussex.
I have been breeding it since 1974 in small numbers; unfortunately over-
wintering the larvae is not easy. They remain very small low down in
the dead brown grass (in the winter they never sit on green blades), at
almost soil level — perfect prey for slugs. By April (after eight months),
they are still less than + in. long! The aberration is quite distinct from
ab. valentini H.B.W., another aberration involving enlarged black markings.
As the aberration occurs in the F.1 generation in approximately equal
numbers, it would appear to be a dominant gene. Pairing two aberrations
produces some examples which are blacker than the others, but it would
require a great deal of breeding to prove that these were the homozygotes,
although this would seem likely. I propose to name this aberration ab.
craskei (see Appendix).

Three examples were shown: —

Male aberration bred 30.6.76, Fl of male ab. x female ab.

Female aberration bred 6.7.76, Fl of male ab. x female ab.

Female aberration with pale russet tinting to hind wings, bred 27.7.75,

F1 of wild caught female ab.

Hipparchia semele (L.) ab. holanops Brouwer

This aberration, which has a total absence of eye spots, occurs in the
same quarry in Dorset nearly every year. In August 1976, R. Revels sent
me some eggs which had been laid on the netting. No grass had been put
in with the female as it had been found the previous year that this was
not necessary. These eggs were an F2 generation from an ab. holanops
taken in 1975. The larvae feed high up on the grass, coming up in the

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 81

summer in late evening as it is getting dark. This aberration is a simple
recessive, not occurring till the second generation and even then below
the numbers to be expected, so the gene may have a slightly debilitating
effect. I only obtained one holanops out of thirteen bred.

A sister of the ab. holanops was also shown with striking bands in the
hind wing.

Pyronia tithonus (L.) ab. excessa Tutt

This aberration breeds out so uncertainly that I feel that more than one
gene is involved, or perhaps it would be better expressed as one gene
with modifiers. It is clearly not recessive as specimens with additional
spots occur in the Fl generation almost in equal numbers to the typical
form (R. Revels, Ent. Record, Vol. 89, p. 43). Out of ten specimens
in an F2 generation bred in 1976, in which both the parents had additional
spots, I was disappointed to find that none had heavily marked additional
spots, only one specimen had two extra spots and four had one extra
spot.

Some localities have quite a high proportion of ab excessa, such a place
being North Hill, Minehead, in 1952. Sometimes the extra spots occur on
one forewing only.

Examples shown: —

Female ab. excessa taken at Slapton, Devon, 30.7.70.

Male ab. excessa with additional spots on right wing only. Taken Somerset,
20.7.52.

Female aberration, completely asymmetrical, both in size of wing and
extent of fulvous colouring. Minehead, 18.7.52.

Male ab. excessa, underside. Slapton, 20.7.70.

I am now going to consider briefly the extreme racial forms of two
satyrid species — Maniola jurtina (L.) and Coenonympha tullia (Miller) —
which illustrate well the build-up of special genes where races are
geographically separated.

Maniola jurtina (L.)

On the Atlantic coast from Scotland to Spain several fine local races
have evolved.

I show first a male and a female taken in 1963 at Clifden, Connemara.
M. jurtina in this district is larger and more strongly marked than the
typical subspecies iernes Graves, originally described from specimens from
Kerry. The two shown are remarkable for the size of their ‘eye’ spots,
being good examples of ab. anticrassipuncta Leeds. It is indeed rare for a
male to have such enlarged spots. Selective breeding from such specimens
would not only reveal the genetics of these large spots but would no doubt
produce some very striking specimens.

Females with very large ‘eye’ spots also occur on the Isles of Scilly, in
the local race cassiteridum Graves. But it is the undersides of females
from Scilly which are so magnificent — almost like a different butterfly.
The males have far larger fulvous patches on the upperside. The fact that
the Scillonian Meadow Browns have been totally isolated for many
thousands of years has made this specialisation possible.

Coenonympha tullia (Miller)

The geographical races are familiar, the two extreme forms being the
sub-species scotica Staudinger found in Scotland and the sub-species
philoxenus Esper in Whixall Moss, Shropshire; the former being pale with
reduced spots and the latter dark on the upperside and heavily spotted
on the underside. In Scotland there occur specimens without any spots at

82 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

all. In Whixall Moss (and also Meathop Moss) aberrations occur with
large elongated spots, this probably being caused by a recessive gene as in
the case of ab. lanceolata in Aphantopus hyperantus (L.).

Aphantopus hyperantus (L.)

In recent years there has been considerable research into the genetics
of aberrations of this species.
ab. arete Miller, New Forest, 18.7.65

Only small white dots remain on the underside of the wings. Almost
certainly the same gene is responsible as in ab. obsoleta Tutt, in which
there is not a trace of any spots, and ab. caeca Fuchs, which is inter-
mediate between the two. It would appear to be another case of a recessive
gene with modifying resistance from other genes —in this relationship I
do not like to use the description ‘multi-factorial’ as this gives the wrong
impression.

The best visual description which I can give of a recessive gene in these
circumstances is as follows: Imagine the splash caused by a stone being
dropped from a given height in a bucket full of liquid; the stone is the
recessive gene, the extent of the splash is the extent of the aberration.
Now the nature of the splash will be affected by the type of liquid in the
bucket, e.g. petrol, water or oil, and also the shape of the bucket. You
could say, therefore, that the nature of the splash is conditioned by three
factors —the stone, the liquid and the bucket. But the liquid and the
bucket cannot create a splash on their own, only the stone (in our simile —
the recessive gene) can cause the splash.

Major A. E. Collier, who was one of the important pioneers in the
breeding of aberrations, crossed ab. caeca with ab. lanceolata in 1964. The
Fl generation specimens were typical but there was a wide range of
aberrations in the F2 generation exhibited at our Exhibition in 1966. It
included specimens with nothing but elongated white dots. Collier pointed
out that ab. caeca is rarer in the female than the male.
ab. lanceolata Shipp

The genetics are similar to the previous aberration. Once again there
is a very wide range in the extent of influence of the recessive gene, the
elongation of the spot varying greatly. I have bred this aberration for
four generations. Another form occurs with elongated spots, which is not
ab. lanceolata and has a rather pale background. I took a female in the
New Forest and, in an Fl generation of 31 specimens, six were similar to
the parent.

I took a mixed gynandromorph at Lyndhurst in 1962, primarily male
but in which on the underside streaks of the paler ground colour of the
female occur.

When breeding A. hyperantus, the females must be provided with shade
if they are to lay eggs. They hate high temperatures and fierce sunlight
and if exposed to it soon die. The dark colouring means they absorb heat
rapidly. In the heatwave of 1976, with temperatures day after day in the
nineties, it was nearly impossible to keep them alive.

The breeding requirements of the members of the next family, the
Nymphalidae, are very different from those of the species we have just
been considering. Let us first consider the small fritillaries.

Boloria euphrosyne (L.)

On 29th May 1966, I put a female on a pot of violets over which there
was netting supported on stout galvanised wire.

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 83

Within five days 150 eggs had been laid on the galvanised wire, a few
on the netting and only three on the violets. By 20th July, a total of 153
larvae, now in their third instar, had stopped feeding, and were taking up
their winter resting place beneath the dried leaves. It is not possible now
to give a detailed report, suffice it to say that only one larva survived
the winter to produce an imago. I am convinced that this was because
the larvae were kept too dry, and I would recommend spraying at least
once a week.

Two male aberrations were shown: ab. pallida Spuler, which has an
almost white background, and ab. albinea Lamb, with pale yellow back-
ground. These were both taken in the same wood, within a few days of
each other, which would suggest that the same gene, probably a recessive,
is responsible.

We now come to best known British example of dimorphism — the
two forms of the female of Argynnis paphia (L.)—the normal form and
var. valesina Esper. The latter is a sex controlled dominant, the gene
being carried equally by the male and the female, but having visual effect
only in the female. I started breeding from var. valesina in 1964 when
I obtained 250 eggs from three females. Do not use a large cheese tub
with netting over it as sometimes recommended; this gets much too hot
and there is a lack of ventilation. Make a netting cage about 3 ft. high
and at least 18 in. in diameter, and provide ample fresh flowers, including
thistle. Nearly all the eggs are laid on the netting. They can easily be
lost as they fall off if the netting is knocked. In 1965, sixty-eight imagines
were bred, including twenty-four var. valesina, in which there was consider-
able variation in ground colour. This varied from a very deep sea-green
in the dark specimens, to a creamy colour in the lightest examples. I tried
an F2 generation, but fertility of this inbred generation was apparently
low as only 18 larvae emerged from 176 eggs. The slide shows a specimen
of the F2 generation which again has a pale background.

Interested in this and finding a female in the New Forest in 1965 with
almost white background, I tried breeding from this. Unfortunately I only
succeeded in obtaining one var. valesina in this brood the next year, and
this was unusually dark, so I failed in my intention. I now show a chart
illustrating the relative emergence dates of typical males, typical females
and var. valesina.

The next slide was of an underside aberration of Mellicta athalia
Rottemburg, bred in 1949 when I bred 31 imagines from a single captured
female. All the larvae, which were fed on Narrow-leaved Plantain (Plantago
lanceolata), were hibernating by 25th September. On 13th February 1950,
I brought the hibernaculum indoors, and all the larvae left the hibernaculum
on 16th February.

Nymphalis polychloros (L.) usually shows little variation. There was a
quite exceptional immigration of this butterfly in the spring of 1948, and
it was common around Tunbridge Wells. On 12th March I saw as many
as four specimens in one suburban road. Six weeks later I caged a female
for egg-laying and she obliged with one batch of 110 eggs and one of 59
eggs, and from these I obtained 128 pupae. The only variation in the
imagines was some extra black scaling on a few specimens. Although a
number of the adults were released, not one was seen in the area of
Tunbridge Wells the following year.

The next butterfly I would like to consider is Polygonia c-album (L.).
This butterfly appears in two different forms —the typical form and f.

hutchinsoni Robs. —and a slide was shown illustrating the differences.
There is a lot of confused thinking about the relationship of these forms
even in the most recent textbooks, so I bred large numbers to illustrate
the relationship of the two forms. The hibernating imagines are of the
typical form; these lay eggs and produce a summer brood, the majority
of this brood are f. hutchinsoni, these emerging first, and some are of the
typical form. The relative numbers and the date of emergence can be
clearly seen in the emergence chart.

The f. hutchinsoni immediately pair and lay eggs and these produce the
typical form seen on the wing in the autumn before hibernating. Those
specimens of the typical form which emerge in the summer brood soon
go into hibernation. Thus in the following spring there are both first
generation and second generation butterflies from the previous spring’s
specimens.

Ladoga camilla (L.) is subject to varying degrees of obliteration of the
white transverse bars by the black ground colour; specimens with partial
obliteration have been named ab. obliterae Robson and Gardner and those
with completely black uppersides are referred to as ab. nigrina Weymer.
This is very artificial as there is every gradation of suffusion of the bar
from slight black scaling to total blackness. It is very probable that the
same recessive gene is responsible for all these aberrations, its effect being
modified by other genes present—-very much as in the case of ab.
lanceolata in A. hyperantus.

In July this year I took a female ab. nigrina in a wood near Winchester.
Two weeks after taking this aberration, I collected 20 eggs from honey-
suckle within a few yards of where it was found and I now have 18
hibernating larvae. Attempts will be made to get several pairings and breed
a second generation.

We now come to that family which provides such wide scope for genetic
research — the Lycaenidae.

With regard to Polyommatus icarus, I have already referred to the
wide variation in the colour of the female uppersides, from brown to
almost pure silvery blue, as in the specimen illustrated taken on Tresco,
Isles of Scilly, which resembles ab. caerulea Fuchs. Many females are of
this colour in the local race found on these islands.

The genetics of the confluence or radiation of the spots on the underside
is still very uncertain. Breeding from a female ab. arcuata Weym., taken
on Tresco in May 1953, the autumn FI generation consisted of 23 males
all of which were normal, except two male basijuncta Tutt, and 20 females
of which 14 were either arcuata, costajuncta or basijuncta, either separately
or in combination. A smaller F2 generation produced rather similar results.
Note the much greater susceptibility of the female to aberration compared
with the male (see R. A. Fisher and E. B. Ford, ‘The variability of species
in the Lepidoptera, with reference to abundance and sex’. Trans. Ent. Soc.
Lond., 1928, p. 367—a paper emphasising the greater variability of the
female sex). It would appear, too, that the different confluent forms are
not genetically separate, and that any genes governing this type of
aberration are responsible merely for the tendency for confluence. L. D.
Young breeding in 1977 from a female Plebejus argus (L.) ab. basijuncta
Tutt obtained an FI generation of five typical and one basijuncta.

Lysandra coridon (Poda) is a butterfly which I have bred extensively. In
1967 my wife caught an ab. syngrapha Keferst., and I have kept the stock

86 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

going ever since, that is for ten generations. This aberration is a sex-linked
recessive, the syngrapha gene being attached to the x-chromosome in the
female. Thus in the first generation all the males are heterozygotes and
carry the syngrapha gene, while none of the first generation females carry
the gene at all. In the F2 generation half the females are ab. syngrapha.
In 1970, in the F3 generation, I bred an ab. syngrapha which was a
somatic mosaic incorporating streaks of the normal brown female colour.
There is some variation in the ground colour of this aberration and in
1974 I bred a syngrapha/viridescens Tutt with continuous dark fringes.

In ab. fowleri South the borders are white instead of black, the white
band being intersected by black nervules. This aberration would appear
to be the result of a simple recessive gene, which receives modifying
resistance from other genes, so that there is every gradation from ab.
ultra-fowleri B. & L. to ab. punctata Tutt.

In July 1971 I took a male ab. infra-fowleri in Dorset and paired it with
a bred female ab. syngrapha. Three years later I bred from this stock two
females which combined in themselves both ab. syngrapha and ab. fowleri.

In October 1972 R. Revels kindly gave me 105 eggs, being the F2
generation from an ab. semi-syngrapha Tutt, taken at Royston in 1971.
I kept this stock going until last year. Ab. semi-syngrapha is, like ab.
syngrapha, a sex-linked recessive. There is, of course, no relation between
them. Again the ab. fowleri gene was introduced and I bred four abs.
semi-syngrapha + fowleri. 1 am showing a slide of L. coridon ab. marginata
Tutt, this being one of an F2 generation from a male ab. marginata taken
in 1971 paired with a typical female. In this aberration the black outer
border of the forewings extends over the blue as far as the discoidal cell.
I bred this strain for three generations but found that you had to select
very good males to get results. It would suggest that this is, therefore, a
very genuine case of a multi-factorial aberration. When breeding the ab.
marginata, an interesting form with dark nervules appeared.

In Lysandra bellargus (Rottemburg), the extent of blue scaling in the
female varies greatly, the extreme blue form being known as ab. ceronus
Esper. I have bred a number with considerable blue suffusion and so has
L. D. Young, and for both of us the bluest females occurred in the spring
brood. It may be that the blue is the product of a gene whose influence is
modified by environmental conditions. More breeding is required.

Lycaena phlaeas (L.) is subject to two major aberrational forms — one
in which the orange sub-marginal band in the hindwings is totally absent
(ab. obsoleta Tutt) or reduced to a series of small streaks (ab. radiata
Tutt) and one in which the ground colour is silvery white (ab. alba Tutt).
L. D. Young who did very valuable work in a breeding programme between
1963 and 1965 in which he obtained continuous broods without diapause
by the use of continuous fluorescent lighting at close range, showed that
ab. obsoleta and ab. radiata are produced by the same recessive gene, the
former merely being the more extreme expression. Ab. alba has been
bred by Dr. J. W. O. Holmes who has shown that both this and the
pale cream coloured ab. schmidtii (Gerh.) are controlled by recessive
genes, although the exact relationship between the two seems still
uncertain.

We now come to the Pieridae. From 1950 onwards a laboratory culture
of Pieris brassicae (L.) was maintained by B. O. C. Gardiner, assisted
by C. F. Rivers, at the Unit of Insect Physiology, Department of Zoology,
Cambridge, the original stock having been collected in the Cambridge area.

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 87

After more than ten years of inbreeding, two aberrations appeared in this
stock, each caused by a gene, later proved to be a simple recessive: an
albino form named ab. albinensis Gardiner (1962) and a form with a blue
tint to the hindwings named ab. coerulea Gardiner (1963). In May 1967,
I was kindly given a batch of eggs of a pure strain of ab. coerulea and
obtained 125 pupae, and also eggs of a strain of the double aberration
coerulea + albinensis and obtained 115 pupae. Although I bred a number
of perfect females of each type, the strain suffered from a serious scale
defect, which was more serious in the males than in the females and
almost all the males were unable to extricate themselves from the pupa-
case. The very few males which did manage to do so, all showed large
areas of scale defect, the scales having stuck to the inner surface of the
case. It is extremely interesting that the aberrations occurred after so
long a period of in-breeding and it would appear that they are classical
examples of the mutation of genes.

In those years when Colias crocea Fourcroy appears in good numbers
in this country (and many of us will remember 1947 when it was very
abundant) quite a number of the pale form of the female (var. helice
Hibn.) is seen. The gene is a sex-controlled dominant affecting the
colouring of the female only, the male heterozygotes being normal in
appearance. I have also bred a very much less common form in which
the colour is intermediate between the rich orange of the normal form
and the milky white of the var. helice, but I only obtained two in a brood
of four. If a wild-caught female is on migration and has only recently
arrived, it can be very difficult to get her to settle down and lay eggs.
I do not know the genetics of this intermediate colour form.

In the last family, the Hesperiidae, occasional aberrations occur in some
of the species, e.g. the ground colour of Thymelicus sylvestris Poda may
be white (ab. pallida Tutt) instead of the usual copper-brown colour, but
the most striking is that form of Pyrgus malvae (L.) in which the white
spots of the forewing join together and form a large white blotch, known
as ab. taras Bergstrasser. The example shown was taken in a wood in
Sussex where this aberration quite frequently occurs —TI have seen eight
on one day. The extent of confluence of the white markings graduates
from just two spots being joined together on the costal margin to specimens
in which most of the centre portion of the wing is white. I have bred
moderate examples of this aberration, but to achieve striking results I
think that it would be necessary to do selective breeding.

I have now given you a brief glimpse of thirty years’ work in sixty
minutes. With only two minutes per year it has not been possible to give
much detail and the review has had to be cursory, but I hope that I have
given you the urge to breed from the next aberration you see instead of
killing it and that you will then come back and tell us what you have
found out.

A new aberration of Melanargia galathea (L.) (Lep.: Satyridae)
from Sussex
by R.,S,, Tuprs,. O.B-E.,, F.R.E.S:
ab. craskei ab. nov.
Since 1970 Mr. R. M. Craske has observed annually in two restricted
localities, one in Sussex and one in Hampshire (now alas ploughed up), a

88 PROC. BRIT. ENT. NAT. HIST. soc., 1978

new form of M. galathea. He informs me that the ratio of the aberrant
form to typical varies from 1 in 20 to 1 in 50. Mr. Craske has given a
series of 27 specimens of this new aberration to the British Museum. It
should be pointed out that this aberration is quite different from ab.
valentini H. B. Williams, which was described in the Entomologist’s Gazette,
Vol. 2, No. 4.

In July 1974, Mr. Craske kindly gave me two living female aberrations
and these produced a total of 180 eggs, 30 of which were given to Mr. R.
Revels. These eggs produced only a few specimens the following year, but
the aberration occurred in this first generation for both of us. Since then
the stock has been kept continuously breeding. It would appear that this
aberration is produced by a dominant gene. Indeed this year (1978) one
brood of eleven specimens bred by Mr. Revels from a male aberration
out-crossed with a wild fresh female consisted entirely of this aberrational
form. This suggests that the male may have been homozygous for this
aberration.

Description

On the upperside and the underside of the forewings of both sexes the
central costal blotch is extended outwards along the costa and firmly
joins the sub-apical bar. This blotch is also extended outwards distally to
become confluent with the marginal markings.

The aberration is slightly variable in the extent to which the white area
between the central costal blotch and the sub-apical bar is obliterated. In
some examples this is almost total.

On the hindwings of both sexes (upper and under) the central band is
broader than in typical galathea, in some cases markedly so.

I have pleasure in naming this very distinct and constantly recurring

aberration after Mr. R. M. Craske, who first discovered it.

CAPTIVITY IN ENGLAND

and E. P. WILTSHIRE

(At the request of H.P., these lines are written by E.P.W., though all
the credit goes to H.P. for obtaining the original larvae and resulting
adults, for the successful overwintering of the latter and for obtaining
pairing and a further batch of larvae, some of which E.P.W. reared to the
butterfly stage.)

Late in May 1977, larvae of Nymphalis polychloros (L.) were found on
elm in Central Spain; they were then in their final instar. They duly
pupated and imagines emerged in England about the middle of June. A
few of these were kept for possible hibernation and were confined in a
large half-barrel with netting over the top, and fed on a solution of sugar
and honey. They showed no signs of pairing and stopped feeding in July.

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 89

Until then the barrel had been kept in a fairly sunny position out of doors,
but thereafter H.P. kept it in a shed.

Having read E.P.W.’s notes (1967 and 1977), H.P. wrote to him on Sth
September saying that as he gathered from these that there might be a
reappearance on the wing in late summer, he wondered whether to
encourage this by bringing them out again. They were keeping together ‘in
a tight huddle’ at the time of writing, although occasionally one or two
woke up and wandered round the barrel.

E.P.W. in his reply stated that he himself had twice taken the butterfly
on the wing in late summer on the East Coast (September 1923 and
August 1928) but these individuals were probably immigrants. He also
mentioned having seen the butterfly after hibernation on 30.i1i.1942 in
Mazanderan, N. Iran; 9.iv.64, near Geneva, Switzerland; 18.iii.72, during
an early heat-wave, in N. France; also in the same district on 7.v.72 and
30.ii1.74; of midsummer individuals he had seen one, on 26.vi.70 in the
East Pyrenees; and he had bred some others from caterpillars in Switzer-
land. He quoted a passage from Verity 1950: 352, not quoted in his 1967
notes: ‘There are plenty of records from Central Europe of its appearance
in mid-autumn and winter on sunny days, but irregularly; however, . . .
during 50 years of observations he (Verity) had never seen it in Tuscany
between August and March.’ From which it appeared that Verity thought
the aestivation of the butterfly would continue without interruption into
hibernation; this might be the case, too, with Spanish polychloros, if the
behaviour was not merely a reaction to local conditions. E.P.W. therefore
recommended H.P. to keep the butterflies in natural conditions at War-
minster. He presumed no pairing would take place until the next spring.

The barrel, with the butterflies inside, remained in the large airy shed
for autumn and winter. At the end of February some of the butterflies
were moving, so H.P. transferred the barrel to a greenhouse, where almost
immediately they began to feed and bask in the sun. On the 2nd of March
a pairing was observed (late afternoon) and the pair remained in cop.
until the following morning. The @2 was put on a small potted sallow
in the greenhouse and eggs were laid in a large batch around a twig on
25th March. The twig, with eggs attached, was removed from the bush
and put in a small plastic box, where the larvae hatched in about three
weeks and were fed on cut elm, pupating at the end of May.

E.P.W.’s batch of larvae gave no trouble feeding up on elm and pupated
on 31st May. with one exception which lagged behind about a week. They
emerged on June 10th (1), 11th (2) and 12th (5); the laggard duly appeared
on June 19th. All were beautiful specimens.

The rearing thus confirmed the long imaginal life and vernal pairing
habit of the Large Tortoiseshell. It would, however, be interesting to know
whether immigrants to England leave Europe before or after aestivation;
perhaps aestivation and emigration are alternatives in the life-cycle, and
one or the other is taken probably depending on local conditions at the
breeding place. A case of immigration after hibernation is reported in the
Presidential Address in this number. There is very little evidence of
migration in the southern part of its range, and I know of no reliable
evidence of a second generation there, still less of such a thing in Northern
Europe.

PHORESY AND COMMENSALISM IN
BRITISH PSEUDOSCROPIONS

by PuiLip E. JONES
(Natural Environment Research Council, Institute of Terrestrial Ecology,
Monks Wood Experimental Station, Abbots Ripton, Huntingdon)
Introduction

Phoresy has long been known to occur in pseudoscorpions and has been
reported from various parts of the world besides Great Britain, including
a large part of Europe, America, Africa and Australia. Pseudoscorpions
have been found clinging (by one or both of their palpal chelae) to the
legs of insects, especially Diptera, Hymenoptera and Coleoptera, and also
harvestmen (Opiliones). They have also been recorded on the bodies of
birds and small mammals. In Britain, most observations have been of them
clinging to the legs of insects or harvestmen.

The attachment of pseudoscorpions to other, larger animals was first
described by an Austrian, Poda, in 1761: ‘Repertus in pedibus muscae,
quos chelis suis firmissime apprehendit’. The first reference to its occurrence
in Britain was made in 1787 by George Adams who recorded that the
eminent coleopterist Marsham found one of these ‘lobster insects’ ‘firmly
fixed by its claws to the thighs of a large fly, which he caught on a flower
in Essex the first week in August, and from which he could not disengage
it without great difficulty, and tearing off the fly’s leg’. The term phoresy
was first used by Lesne in 1896. Since it was first described, phoresy by
pseudoscorpions has been the subject of numerous notes and papers,
especially extensive reviews in Britain by Kew (1901) and, abroad, by
Vachon (1940) and Beier (1948).

This paper collates both published and unpublished references to phoretic
behaviour in British pseudoscorpions. The records date from 1950, except
where no records since then were available or where the use of older
records contributed additional important information. (The administrative
counties referred to are those in existence prior to the Local Government
Act 1972.) Records of species from the nests of social insects, birds and
small mammals are also included in this paper and are treated under
commensalism. The data will be reviewed to determine the light they throw
firstly on current views on phoresy and secondly on the nature of relation-
ships with other animals.

I am indebted to the various museums and individuals who have sent
me records or preserved specimens for identification and they are duly
acknowledge after the appropriate record(s).

Dendrochernes cyrneus L. Koch. Attached to leg of Phymatodes testaceus
(L.) (Col.: Cerambycidae), Richmond Park, Surrey, June 1914 (H. W.
Kew).

The occurrence of pseudoscorpions attached to the legs of insects seems
to be confined to the family Chernetidae in the British Isles. This is
probably related to the fact that many insects, especially flies, occupy
similar habitats to the Chernetidae and also have a similar period of
greatest activity (May-September, occasionally October). Members of the
Chernetidae are mostly found in grain/straw residues, vegetable detritus
and compost and manure heaps (although there are occasionally records
of specimens from woodland leaf litter and from under the bark of trees).
L. nodosus is by far the commonest species of this family demonstrating
phoretic behaviour. It occurs frequently in compost and manure _ heaps.
The common house-fly, Musca domestica, is a regular visitor to such heaps
during the summer months. The female selects decomposing organic matter
as a breeding ground and thus it is possible that an adult L. nodosus
will come into contact with a female house-fly when she settles to lay her
eggs (Jones 1970). It is interesting to note that three of the specimens of
L. nodosus recorded above are phoretic males. Although this is a very
small number compared with the total number of phoretic individuals
on record, it is significant in view of the fact that both Vachon (1947) and
Beier (1967) assert that it is only usually gravid females which are phoretic
(see Discussion below). Like L. nodosus, P. scorpioides is frequently found
in heaps of vegetable refuse and could come into contact with flies in
exactly the same way.

C. cimicoides and D. cyrneus are typically found under the bark of
decaying trees. C. cimicoides could have attached itself to the ichneumon
if the latter had alighted on the dead tree stump during its search for a
suitable host to parasitize. The Cerambycidae are wood-feeding insects
and therefore D. cyrneus might be expected to come into contact with
members of this family fairly frequently.

Species found attached to the bodies of arthropods other than insects:
Lamprochernes nodosus. Attached to Opilio parietinus (Deg.) (Opil.:
Phalangidae), Wye, Kent, 1944 (J. Sankey); attached to Phalangium opilio

92 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

L., Wye, Kent, 1944/45 (J. Sankey); attached to Mitopus morio (F.), Wye,
Kent, 1946 (J. Sankey); two nymphs attached to Nelima sylvatica (Simon),
Dale, Pembs., 1948 (J. Sankey); attached to P. opilio, East Bergholt,
Suffolk, 1948 (J. Sankey).

Allochernes dubius. One adult attached to leg of Mitopus morio, in leaf
litter, Wytham Wood, Berks., September 1953 (Wytham Ecological Survey);
2 2 attached to legs of Oligolophus meadii Cambridge, in a garden, Esher,
Surrey, September 1954 (J. Cloudsley-Thompson).

All the records in this category are of pseudoscorpions phoretic on
harvestmen. This occurrence is not as common as pseudoscorpions being
phoretic on flies and appears to be restricted to the Chernetidae. This is
consistent with Beier’s (1948) suggestion that species living in more open
and drier habitats, such as members of the Chernetidae, will frequently
attach themselves to more mobile creatures because of a modification of
their original hunting instinct.

The instance of two nymphs being attached to Nelima sylvatica is of
interest as it is the only record, as far as I am aware, of nymphs being
phoretic. It is unlikely, because of their size, that they would be attacking
the harvestman for food or even utilising it as a means of transport and
so this must be regarded as an accidental occurrence of unknown
significance.

Discussion—the function of phoresy

The above records show that pseudoscorpions do cling on to the bodies
of larger arthropods and animals and that they may be transported as a
result. Why they do this is not known with any certainty. Two main
theories exist. First, phoresy is predatory in nature. The pseudoscorpions
are simply attacking their host for food. Secondly, phoresy is ‘the non-
parasitic association of one kind of animal with another in order to obtain
transportation’ (Webster’s Third New International Dictionary).

Most of the records of phoresy refer to females and both Vachon (1947)
and Beier (1967) link phoretic behaviour with the restlessness and intense
hunger particularly experienced by gravid females. From the date of
capture of his phoretic specimens (end of August in the case of Allochernes
dubius) and the presence of spermatozoa in the spermathecae, Vachon
concluded that fertilisation of the females had just finished and that it was
this that had released in them an intense hunger, driving them, in cases
where the normal smaller prey had become scarce, to seize any larger
insect/arthropod passing within reach of them. Transport could then have
resulted if the insect/arthropod moved off before the pseudoscorpion had
relinquished its hold. (In the case of pseudoscorpions being carried on the
bodies of birds or small mammals, it is unlikely that they are trying to
attack them for food and one must therefore conclude that it is movement
of the animal or possibly bodily warmth which is the stimulus causing the
pseudoscorpions to cling on to them.) Vachon also concludes that male
pseudoscorpions probably do not exhibit phoretic behaviour because they
have different behaviour patterns generally and have a much more restricted
range of movement within the habitat. This is because the advantage of
movement to males is different to that of females which need to cover
larger areas to satisfy their intense hunger.

True phoretic behaviour has not been recorded in Britain in the
Chthoniidae and Neobisiidae, but occurs frequently in the Chernetidae and
Cheliferidae (Weygoldt 1969). Six of the ten British members of the
Chernetidae and one of the three British members of the Cheliferidae have

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 93

so far been shown to demonstrate phoresy. Members of the Chernetidae
and Cheliferidae have a fairly large body size, are relatively dark in colour
and possess a somewhat heavy exoskeleton (compared with the Chthoniidae
and Neobisiidae). The problem of desiccation is not so great and they
are therefore found associated with relatively dry habitats, which are often
temporary and less stable ones (C. Clayton Hoff 1959), such as barn refuse
and animal nests (although some of them have exploited more permanent
habitats, such as the bark of trees). They also possess spermathecae and
are able to store sperm for prolonged periods (Legg 1975). Thus, a female
with spermathecae fertilised, and stimulated by a desire for food, can
reach another habitat as a result of phoresy and on reaching that habitat
can find a new source of food and initiate a new population. Here, phoresy
can be regarded as a mechanism which will facilitate dispersal to another
habitat when the temporary habitat in which the pseudoscorpions are
living is threatened.

The Chthoniidae and Neobisiidae are unable to store sperm for pro-
longed periods and are associated with permanent and fairly stable habitats,
such as woodland leaf litter and soil. Southwood (1962) regards phoresy
to be the main, if not the only, regular migratory movement in pseudo-
scorpions but in view of the lack of records of phoretic behaviour in these
two families, it seems clear that there must be other means of dispersal
for these in addition to phoresy. The subject bears further investigation.

In conclusion, it seems clear to me from the evidence given above, that
phoretic behaviour in pseudoscorpions has developed as a modification of
their original hunting instinct (particularly in pregnant females), which
causes them to seize large arthropods/animals which go past, at the same
time allowing themselves to be carried along by them. The association
is only profitable to one animal—the one being transported—and is moti-
vated by stimuli arising only within that animal. These stimuli, released
by the inadequacy of the biotope, arise from hunger and the need to find
a more favourable environment for the development of the young. Probably
the most important outcome of phoretic behaviour is the geographical
distribution of the species.

Records of commensalism

Toxochernes panzeri (C. L. Koch). In nest of L. fuliginosus, Oxshott,
Surrey, about 1902 (H. St. J. K. Donisthorpe); 1 @ in debris of nest of
Vespa crabro L. (Hym.: Vespidae); in tawny owl pellet, Wytham Woods,
Berks., December 1950 (O. Gilbert); one tritonymph in debris in nest of

None of the British genera of pseudoscorpions is restricted in habit
to associations with social insects. It is probable that most individuals find
their way into nests of social insects purely by chance. This is undoubtedly
the case with members of the Chthoniidae and Neobisiidae, which are
ground-dwellers, mainly in moss and leaf litter, and in the case, cited
above, of C. cimicoides, which usually lives under bark. They would easily
find their way into the nests of social insects in such habitats and once
there would find favourable temperatures and an abundance of small
anthropods on which to feed, e.g. small mites, beetle and fly larvae. As
synoeketes, they seem to do no harm to their hosts and their hosts seem
to treat them with indifference. Donisthorpe (1927) showed this by intro-
ducing specimens of P. scorpioides into observation nests of F. rufa:
‘ .. the ants treated them with indifference. If a rufa worker was forced
to take hold of a chelifer (pseudoscorpion), it dropped it at once.’ The
distribution of pseudoscorpions from nest to nest and the founding of new
colonies in other localities probably occurs phoretically.

Pseudoscorpions may be brought into birds’ nests on nest-building
materials, such as dried grass or straw, or phoretically on parasitic or
nidicolous flies, or possibly even on the bodies of the birds themselves. In
the case of C. museorum and C. cimicoides, which are bark-dwelling species,
they may arrive in nests during the course of their normal wanderings
in search of food. P. scorpioides and T. panzeri are frequently found in
hay and straw debris and therefore it is most likely they find their way
into nests on the nest-building materials.

Birds’ nests provide favourable conditions for pseudoscorpions to live
and breed—warmth, a high humidity and a plentiful supply of food in the
form of mites and the young larval stages of various insects. This habitat
is only a temporary one though and pseudoscorpions may be distributed
to more favourable habitats on the bodies of the birds when they leave
the nest. There is, as yet, no evidence to confirm this.

Chernes cimicoides. One nymph in grey squirrel nest in ash tree, Chosen
Hill, Glos., May 1958 (R. S. George).

C. ischnocheles and N. muscorum belong to genera, whose members are
more usually found in ground litter, rotting vegetation and soil. P.

Scorpioides, T. panzeri and C. cimicoides are frequently found under the
bark of dead or rotten trees or logs. As all these species occur in similar
habitats to those in which small mammals build their nests, it seems likely
that the association of pseudoscorpions with small mammals has come
about quite by chance. As with birds’ nests, mammal nests provide a
readily available source of food for pseudoscorpions in the form of mites
and larvae of Coleoptera and Diptera. Pseudoscorpions are undoubtedly
transported to other habitats on the bodies of the mammals, having possibly
being stimulated to cling on to them by the presence of warmth generated
by the mammal’s body. This certainly seems to be the case in Lasiochernes
pilosus (Ellingsen), a central European species absent from Britain, that
lives in the nests of moles (Weygoldt 1969).

In conclusion, one may say that the association of pseudoscorpions with
social insects, birds and small mammals is primarily one of commensalism
rather than phoresy, although phoretic behaviour may be employed in the
distribution of the species to new habitats. This commensal relationship
comes about purely by chance, the species involved occurring in similar
habitats to those in which social insects, birds and small mammals build
their nests. The pseudoscorpions benefit from the relationship by finding
favourable temperatures in which to live and breed and particularly by an
abundance of small arthropods on which to feed.

BUTTERFLIES IN SPAIN: SIERRA DE ALCARAZ, SIERRA
DE GUDAR, SIERRA DE JAVALAMBRE

by RusseLL F. BRETHERTON
(Folly Hill, Birtley Green, Bramley, Guildford, Surrey, England)
and OTAKAR KUDRNA
(Portsmouth Polytechnic, Department of Biological Sciences, Portsmouth, England.
Present address: Museum Alexander Koenig, Adenauerallee 160, D-5300 Bonn,
W. Germany)

During an expedition to Spain in 1976, besides some well known areas,
Sierra de Alcaraz in proy. Albacete was visited by both authors, and
Sierra de Gudar and Sierra de Javalambre in prov. Teruel by Kudrna
alone—returning there after a previous visit made in 1974 which is also
reported here—after Bretherton’s return to England. As we have been
unable to find published accounts of the Rhopalocera and Grypocera of
these Sierras, we list below the species which we recorded there, with
comments, relating some of them to the distribution maps of Spanish
butterflies previously given by Bustillo and Fernandez-Rubio (1974) in
their admirable book on Spanish Rhopalocera.

The Sierra de Alcaraz is a considerable mountain massif in prov.
Albacete, reaching 1,790m. at its highest point; it forms part of the
watershed between the river systems of the Guadalquivir, flowing to the
Atlantic, and the Mundo flowing to the Mediterranean. Its central valley,
at about 1,100 to 1,200m., is covered with mixed deciduous and coniferous
woodland and is well watered by small streams bordered by damp meadows.
According to the geological map the barer summits consist of triassic
limestone, the lower ground of lias. The massif is crossed by a secondary
road for some 60km. from the town of Alcaraz over two passes and
through the central valley to the village of Riopar below its steep southern
escarpment. We collected on three days—13-16.vil.1978—-mainly near this
road, staying for the nights at a small quiet pension in Riopar.

Sierra de Alcaraz produced a number of surprises. Of the 63 species
whose presence was verified, five are not shown on the distribution maps
(Bustillo and Fernandez-Rubio 1974) to occur at all in prov. Albacete.
The discovery of Brenthis daphne Denis & Schiffermiiller, which was
abundant in several places, has already been recorded (Bretherton and
Kudrna, 1977). This represents an extension of its range by some 160km.
southwards from Serrania de Cuenca (Amor, 1977) and even more from
the other localities in east-central Spain, where the species has also been
very recently recorded (Garcia and Leyva y Vega, 1977; Ortiz and Lyeva,
1978; Bustillo, 1978). Much the same is true of Brenthis ino Rottemburg,
of which a few worn but clearly identifiable examples were taken on
damp ground near a spring. The same is true of the surprising capture of
a single female Agrodiaetus, probably referable to fabressei Oberthiir rather
than to ripartii Freyer, which was caught on the bare slopes above the
descent to Riopar. Limenitis reducta Staudinger, of which examples were
taken in several places in the central valley, is mapped only so far as the
border of prov. Cuenca, some 80km. to the north. Plebicula amandus
Schneider is also mapped in southern Spain only on the Sierra Nevada.
Besides these additions to the list of butterflies for prov. Albacete, Mellicta
deione Geyer, Brenthis hecate Denis & Schiffermiiller and Argynnis paphia
(Linnaeus), all of which we found commonly in the Sierra de Alcaraz,
are shown only on distant fringers of the province. It is apparent that that
Sierra, possibly because of its abundance of water and rich vegetation,
both permits a considerable intrusion of northern species into southern

98 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

Spain and also fills part of the gap in distribution for some other species
which were previously known only considerably north and south of it.

The Sierra de Javalambre and the Sierra de Gudar are parts of the
geologically very complicated mountains of prov. Teruel and Cuenca; but
they lie to the north-east of the area surrounding the well explored area—
rich in Lepidoptera—of Albarracin, Bronchales and Tragacete. The Sierra
de Javalambre lies to the south of the main trunk road from Teruel to
Sagunto, where it joins the coastal motorway just north of Valencia. Its
highest point is 2,200m., but only the lower levels of 1,200-1,500m. were
investigated on 22 and 23.vii.1974 and 3 and 4.viii.11976, mainly along the
small road which passes through the villages of Manzanera and Torrijas
and along forest tracks leading to the higher Sierra. This area is mostly
lias, with triassic limestone on the summits, with a small stream running
through the main valley, bordered with cultivated agricultural land in
some places and wooded (mostly pine trees) or covered with small areas
of garigue shrub in others, situated mostly on drier slopes a little way
from the stream itself. The Sierra de Gudar is situated north-east of the
same main trunk road mentioned above; it is crossed by a secondary road
which runs north from Mora de Rubielos. The highest point of the Sierra
de Gudar is 1,909m. The areas collected on 20 and 21.vii.1974 and 30.vii-
2.viii.1976 were along the above mentioned secondary road between the
passes Puerto de Alcala and Puerto de Gudar and in the vicinity of the
village Alcala de la Selva, at altitudes 1,400-1,850m. These mountains,
covered by a mixture of vegetation types (woodland, meadows, pastures,
etc.) are cold, much cooler than the Sierra de Javalambre, even in summer,
as is especially noticeable at night and early in the morning; also the
butterflies, especially at higher levels in somewhat more exposed localities,
start flying much later in the morning than in other parts of central and
east-central Spain at comparable altitudes. Unlike Javalambre, Sierra de
Gudar is geologically eocretacian. The Hesperiidae of Sierra de Javalambre
and Sierra de Guda were not recorded, but those collected incidentally
were given to Dr. R. de Jong (Rijksmuseum van Natuurlijke Historie,
Leiden).

The following species were collected and recorded in the above described
three Spanish Sierras, which are in the list of species abbreviated for
convenience thus: Sierra de Alcaraz=A, Sierra de Javalambre=J, Sierra
de Gudar=G. For ease of reference the order of families, genera and
species and their nomenclature also follows that used by Bustillo and
Fernandez-Rubio (1974).

FOR SALE — HEWITSON ON BUTTERFLIES, PRICE 6d.
by B. O. C. GARDINER
(Agricultural Research Council, Unit of Invertebrate Chemistry and Physiology,
Department of Zoology, Downing Street, Cambridge, England)

Between 1867 and 1877 W. C. Hewitson published a number of important
pamphlets describing new species of Lepidoptera. This was apparently done
in order to claim priority of nomenclature in advance of his more com-
prehensive and expensive illustrated descriptions which were slowly being
published in parts. Taxonomically these leaflets are of great importance
and they have recently been reprinted (Higgins, 1972).

It is stated that they are one of the rarest of modern entomological
publications and it is not known if they were ever offered for sale. I now
have definite evidence that the first one at least was offered for sale and
it is also my belief the publications may be much commoner than is
generally believed.

Proof of the first number to be issued having been advertised appears
on the verso of the back wrapper to a part of Hewitson’s Illustrations
where it states below other advertisements for his more expensive works
with coloured plates: —

Above this is the statement that Part III of the Lycaenidae, with 16
coloured plates is ‘just published, April Ist, 1867, price 25s.’ (see fig. 1).
It is therefore reasonable to assume that this part of the illustrations
appeared between these two dates. It is also interesting that the advertised
date of publication is five days in advance of that generally taken, April
20th, 1867. It seems probable that an examination of other similar
ephemeral covers would reveal further advertisements and prices for the
other parts.

Hewitson’s works nowhere appear to be that common, but are present
in most of the major Libraries. His publications on birds and butterflies
were however lavishly illustrated with coloured plates and like so many
similar works of the time, expensive to all but the leisured classes and
produced in small editions. His ‘Descriptions’ however, octavo size, 16 to 36
pages, un-illustrated, published over a ten-year period, one of which, as
now know, was priced at 6d. are likely to have been in larger editions,
possibly several hundred. The Contemporary Journals such as the Ento-
mologist and Entomologist’s Monthly Magazine were also priced at 6d.
per issue (1/- for double numbers) and the ‘Descriptions’ could therefore
have been afforded by the average Entomologists. In view of the price
stability of the Victoria era, I consider it probable that all the numbers
were sold at the same price as the first. Even if individuals were: not

interested, there were hundreds of small local Entomological and Natural
History Societies in existence at the time and many of these possessed
libraries.

I have in my possession several parts of the ‘Descriptions’. They are as
follows: —

The first four parts of ‘Equatorial Lepidoptera collected by Mr. Buckley’
bound in a Continental style with title page and index and bearing on the
flyleaf ‘Donatio auctoris’ with on page one in the same hand, ‘Hewitson’.
It also bears the label of ‘Ortner, Wien No. 7196 Lepidoptera’. Ortner was
a well-known dealer of the Austro-Hungarian Empire.

My ‘Descriptions of new species of Lycaenidae’ has in its early days been
bound up with other pamphlets into a book. This is a common occurrence.
Small items like this either end up in a box, gather dust and get forgotten,
get thrown out or get bound up with other material, the mix depending
on the preference of the owner. When they pass into other hands,
particularly those of dealers, they are then frequently torn apart into
their original parts and re-distributed. That is what has happened here.
It was obtained through an advert in the Insektenbourse.

My ‘Bolivian Butterflies collected by Mr. Buckley’ bears the stamp of
the Natural History Society of Northumberland, Durham and Newcastle-
upon-Tyne and the shelf mark or catalogue reference EAh5. It was an
uncut copy! Having also seen a copy bearing the stamp of the Norwich
Natural History Society, I am therefore of the opinion that many copies
may well be lying around in local libraries, if they have not already been
disposed of. Very many libraries have in recent years been disposing of old,
little or never used, stock, either to make room for new, or to raise
funds. Many items such as these Hewitson pamphlets have been thrown
onto the market and lately I have seen the parts on Lycaenidae, Equatorial
Lepidoptera and Bolivian Butterflies advertised in booksellers’ catalogues.
They would be worth keeping an eye open for.

HOW SWALLOWTAIL BUTTERFLIES PASS THE NIGHT

by KATE GARTON and MrrRIAM ROTHSCHILD
(Ashton Wold, Peterborough)

Very few of us in the U.K. have visited the Archbold Biological Station
of the American Museum of Natural History. We were two of the lucky
ones. The station is located in the southern part of the Florida peninsula,
mid-way between the Atlantic and the Gulf of Mexico, in slash pine/sugar
sand country. All members of the museum staff can work there free.
One wishes that our Natural History Museum could collaborate in such
an enterprise, for we can think of no greater stimulus to systematics or
taxonomy than a visit to the Archbold.

All entomologists enjoy pottering about, and the station provides an
inspired synthesis of serious research and watching butterflies in the sun.
Furthermore the secluded 2,000-acre estate in which it is situated is
sufficiently unspoilt and undisturbed for the wild life round the central

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 103

building to have become as tame as animals on an uninhabited south sea
island. You can set up a feeding tray for scrub jays in the garden of your
bungalow and you won’t require a hide or field glasses to see which
butterflies are accepted or rejected. For a naturalist with a well planned
piece of field work in mind this is paradise on earth.

On both occasions when we were at the Archbold Station three species
of swallowtails were common in the garden, Papilio cresphontes Cramer,
Papilio palamedes Drury, Battus polydamas Linnaeus. Four others were
seen only as single individuals.

We have often wondered what butterflies do when they wake up and
drop off to sleep. Is there a preparatory phase equivalent to reading in
bed? Here was the chance to watch the giant swallowtail settling down
for the night. In early March in Florida there are about 12 hours of
daylight and the maximum temperature at the time was 80°-91°F. by day
and 66°-68°F. by night.

Up to 4.15 p.m. the females of P. cresphontes were ovipositing on the
young leaves of Citrus trees. At 4.20 p.m. all the specimens in that area
were to be seen together on beds of flowering plants or bushes, where
they put in 25 minutes intensive feeding.

P. cresphontes goes to bed early, about 30-40 minutes before either P.
palamedes or B. polydamas, and a good hour before the skippers which are
both notoriously early risers and late feeders. At about 4.40 p.m. five
specimens left the flowers and began to fly about slowly between the trees
just above our heads, obviously searching for a suitable roosting site. They
eventually decided on a small Laurel Oak (Quercus laurifolia) about 20 feet
in height and surrounded by towering pine, bamboo, pepper, mango and
other introduced species. The branches were laden with dried pine needles
which had fallen from the trees above. This Laurel Oak was the initial
choice of these butterflies on three consecutive nights.

It was difficult to follow each individual in the deep shade. Moreover
the black and yellow pattern tones in so well in these dappled surroundings
(Fig. 1) that it is sufficient only to let one’s eyes wander for a second
to lose the specimens for good. One ‘pair’ however kept very close
together, and settled within a few centimetres of each other on the slender
outermost twigs and leaves, about 10 feet from the ground. They imme-
diately spread their wings horizontally towards the setting sun. This
behaviour is reminiscent of Heliconius charitonius tuckeri (Comstock and
Brown) which we have seen assembling here in small communal roosts,
except that this latter species waves its wings gently to and fro eventually
closing them, whereas the swallowtails sat motionless—each forming a
flat-topped perfect triangle, tilted at an angle to catch the last rays of
the sun, and held them open indefinitely.

Between 5 p.m. and 6.15 p.m. these butterflies were disturbed six times,
but after flying around they returned to the same tree. On four occasions
the disturbances were caused by other giant swallowtails, either latecomers
or roosting specimens which had been shaken out of neighbouring trees
by squirrels. They attacked the sleeping butterflies mercilessly, striking at
them again and again. The ‘pair’ in view flickered their wings rapidly
in unison but the pugnacious intruders returned to the attack and soon
all five would-be roosters were on the wing. Squirrels jumping into their
tree was the cause of the next flurry and finally a car passed by, and all
five butterflies once again rose into the air. At 6.15 p.m. the largest of the

104 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

‘pair’ was once more back in the outermost branches, with wings spread,
rocking almost imperceptibly in the breeze. By seven o’clock it was too
dark to see them without a torch but up to eleven o’clock they had not
moved. Next morning about 7.20 a.m. squirrels again created a disturbance
and one butterfly began to fly around in the half-light, but we kept our
eyes fixed grimly on the largest of the ‘pair’ which did not stir. With
wings spread and tails at a slight angle in classical swallowtail fashion,
it slept on for a total of 14 hours 25 minutes. At 8.45 a.m. the right
forewing twitched slightly and it flopped out of bed. There was no
warming-up process. Observers and observed then moved away in search
of breakfast, one decidedly more stiffly than the other.

Unlike P. cresphontes, P. palamedes roost alone. This is scarcely surpris-
ing since its violent and pugnacious temperament creates a barrier to
companionable night life. This swallowtail attacks almost any species,
including its own, which it encounters during periods on the wing,
particularly on arrival at a communal nectar source, when it strikes,
apparently at random or capriciously, at any other butterfly in sight.
Especially as evening approaches it engages in long strenuous combats with
members of the opposite sex—a pair sometimes battering each other
continuously for 13-20 minutes. Whether such flights are sexual in nature,
with the male trying to subdue a reluctant female by force, is not known.
Suffice to say both butterflies may receive severe injuries in the process
(Fig. 2), mostly to the hind wings or ‘tail’ area—injuries which could
easily be mistaken for bird beak marks (Rothschild, 1978). As bedtime
approached P. palamedes made sudden long circuitous flights from the
feeding grounds, often returning to the flowers, but soon or later disap-
pearing around 4-4.30 p.m. Sleep would become virtually impossible unless
a discreet approach was made from the communal feeding area to the
roost. During these flights they are almost impossible to track amidst
the branches of the trees and the luxuriant growth of creepers and vines.
By observing flight lines and organising observation posts—and only after
many repeated failures—were we eventually able to observe these butterflies
roosting. Occasionally they chose sites among pine needles twenty feet up,
but usually the situations selected were in bushes within 5-6 feet of the
ground. Unlike P. cresphontes which, unless disturbed by squirrels, or
other untoward events, remained all night in the original site of their
choice, P. palamedes is a tremendous fidget. For quite long periods, 20
minutes or more, it remained with its wings fully spread in the permanent
roosting position characteristic of P. cresphontes, and then suddenly
fluttered off to select another site, sometimes close at hand but at other
times far distant. This performance may be repeated several times, with
quite a lot of wing-fanning in between. Eventually when it does go to
sleep it is with wings closed held vertically above the thorax, but any
disturbance in its vicinity elicits a few rapid wing claps.

Awakening in the morning the wings were fully extended in the direction
of the rising sun; occasionally the butterfly would shut them again—like a
man reluctant to leave a comfortable bed who temporarily pulls the bed
clothes over his head—and remained motionless for several minutes. At
last it decided to take off, but resettled almost immediately on a patch of
sunlit grass and stretched fully towards the rays of the sun. The warming
up, like the settling down process of this species, is a protracted affair.

Battus polydamas, the commonest species at the Archbold Station in
November, also roosts singly. It is the last of the swallowtails to leave the

flowering spikes of the red Pagoda flower (a species of Clerondrum intro-
duced from Asia) around 5 p.m. It flew directly upwards into one of the
surrounding trees, preferably a pine, immediately chose the appropriate
spot between a bunch of the long pine needles—some 12-15 feet off the
ground—settled, snapped its wings together and never moved again for
approximately 16 hours. Even when struck at by another passing individual
they did not move their wings. Similarly it left the tree in the morning
without any preliminary movements equivalent to ‘stretching in bed’. On
overcast days B. polydamas extended its roosting period to 19 hours, and
possibly longer. On one occasion this butterfly was found asleep beside a
large dragonfly.

Of the four species represented in the garden by single individuals we
were able to track down Papilio glaucus Linnaeus one afternoon feeding
at 2.55 p.m. on a patch of Sedum (which had just come into bloom along
the main asphalt drive), in company with a single P. cresphontes. After
two hours at this nectar site the butterfly flew around for about one
minute, apparently reconnoitering the roosting possibilities, but returned
to feed for a further five minutes. This manoeuvre was repeated several
times. It then suddenly rose to considerable heights above the trees, gliding
down to settle for the night in the outermost twigs of a pine immediately
above the road. The wings were closed vertically and after a slight fanning
movement the butterfly remained perfectly still for 15 hours.

Papilio troilus Linnaeus however completely defeated us. This butterfly
patrolled a special area which surrounded the principal feeding site. It
excited animosity even in the usually unexcitable B. polydamas which drove
it off—sometimes several in unison—whenever it attempted to feed on the
Pagoda blooms. At intervals of about 15-20 minutes during the day it
passed at high speed through the glade. Again and again as dusk fell it
entered the main roosting area, flying in a more leisurely fashion and
vanished, as if by magic, under our very noses. Although we knew within
inches where it snapped out of sight we failed completely to find its roosting
site. Some other observer was evidently smarter than we, for on our last
afternoon at the Archbold, waiting around 4.30 p.m. in the roosting area,
we found the four bodiless wings of our troilus lying spread out in
butterfly array on the ground. Since there were no marks at all on the
wings we assumed a small rodent was the culprit. We were utterly dismayed:
it was like losing an old friend.

This brief account of the sleeping habits of four species of swallowtails
demonstrates that, although the group as a whole share a general pattern
of behaviour (Table I) each species displays characteristic features of its
own. P. cresphontes, for example, roosts communally with its wings spread
horizontally, while the other three are lone roosters with wings closed
above their backs. B. polydamas dispenses with any late evening flights
and never moves so much as a centimetre once it has settled down, while
the pugnacious palamedes engages in long circuitous preroosting per-
ambulations and—like one of the most distinguished fellows of the Royal
Entomological Society—demonstrated its ability to clap while sound asleep.

A note on the Archbold Biological Station

The station was established in 1941 by Richard Archbold and is supported by
the non-profit biological research organisation which he created, and which also
finances offices, collections and curatorial staff in the Department of Mammalogy
at the Museum.

Five of the major terrestrial habitats of the region are found in the main
property stations (2,000 acres). These include South Florida slash pine/turkey
oak woodland, sand pine scrub, scrubby flatwoods, low flatwoods and bay tree
forest. The station also owns a tract of about 80 acres on the north side of
nearby Lake Placid. The biota of the region is unusually diversified. The dry
pine-oak habitats contain a number of endemic forms of plant and animal life
such as the Florida scrub jay, scrub lizard, sand skink and Florida mouse.
Aubudon’s caracara, sandhill crane and burrowing owl are characteristic of the
nearby flatland region. (A dead armadillo on the highway quickly attracts a
hoard of vultures.) The number of species thus far recorded on the station
property includes 15 fish, 54 amphibians and reptiles, 142 birds, 36 mammals,
about 350 vascular plants, and more than 1,100 insects and other invertebrates.
It is not unusual to see half a dozen species of swallowtail butterflies in the
station garden.

The mean annual temperature is about 72°F. with an average annual rainfall
of approximately 55 inches with over 60% falling (mainly in the form of short
but heavy thunderstorms) between June and September. Maximum-minimum
summer temperatures are 93°F.-69°F. and winter temperatures 76°F.-49°F.

Research centres on the ecology of the highland area of southern peninsula
Florida, with special emphasis on the natural ecosystems represented on the
station. The several distinctive and completely protected habitat types together
with well equipped laboratories and other facilities combine to make the station
an ideal site for in-depth long-term ecological investigations. In the course of
their studies the laboratory staff and visiting scientists have marked and released
thousands of individuals of many kinds of reptiles, birds and mammals on
permanant sampling grids in each major habitat or on the whole station property.

The laboratory is supplied with most standard equipment and there are
invaluable reference collections and library facilities. There are also outdoor
cages for animals (two with concrete pools) and a greenhouse. My only suggestion
for improvement of this fantastic set-up is that nectar sources for butterflies and
insects in the immediate vicinity of the laboratory—the garden area—could be
increased with advantage.

Living facilities for visiting workers include rooms in the main building or
one, two or four bedroomed, air-conditioned cottages (equipped for self-catering,
although visitors can have their meals in the main building). Charges for food
and lodging are nominal (a current fee schedule is available).

Persons wishing to utilise the station’s facilities must submit an application with
a research programme. Applications are reviewed by an Advisory Board and
should be received as far as possible in advance, preferably two months, of the
proposed date of the visit to allow sufficient time for review by the Board.
Application forms and additional information may be obtained from The Director,
Archbold Biological Station, Route 2, Box 180, Lake Placid, Florida 33852.

DATE OF THE ARRAN BROWN AND SCOTCH ARGUS
(a correction)

In our last number in the current volume (1/2):5 and 55, we gave an
account of the exhibit of a 2 Erebia ligea (L.) captured in the Scottish
Highlands ‘in July 1969’ by T. J. Daley ‘together with many E. aethiops
Esp.’.

Our member C. Edwards of Oban, Argyll, wrote to us to say that in
his experience E. aethiops males start flying in late July and the first
females a week or ten days later. He considered ‘Sth July’ too early a date
for aethiops and pointed out that Higgins & Riley (Field Guide) give
‘end of June to August’ for the flight season of ligea.

While confirming the fact of the capture by T. J. Daley of ligea in
Scotland, we must apologise for an error of date that crept in due to the
circumstances of organising data of exhibits at the Annual Exhibition. On
learning that the Society wished to photograph for publication his ‘aethiops
form’ (as he thought it), Mr. Daley was questioned about the date and
replied ‘late July 1969’, speaking from memory. Later, after confirmation
of the identity of the specimen, he changed this, both verbally and in
written account, to ‘Sth August 1969’. A confusion occurred in drawing
up the account between the two versions which became combined. We
have no doubt of the genuineness and circumstances of Mr. Daley’s capture
of ligea, but must request readers to correct both this mistake and one
or two others which, we regret, occurred in our report and plate on the
Annual Exhibition.—Editor.

EXHIBITS

Dr. A. A. ALLEN — (i) A 2 example of Apanteles pinicola Lyle (Hym.,
Braconidae) bred 25.ix.1977 from an immature larva of Thera obeliscata
(Hiibner) (Lep., Geometridae), the grey pine carpet. The young host larva
was beaten, together with other larvae of the same species, from low
branches of Pinus sylvestris, 3.ix.1977, on Brownsea Island, Dorset. The
host larva was killed on 12.ix, on which date the parasite larva spun its
rosy-tinted white cocoon, attaching it to the dead host skin. A. pinicola
seems to be a regular parasite of Thera spp., but its distribution in Britain
is uncertain. (ii) A 2 example of Platylabus pulchellatus Bridgman (Hym.,

PROC. BRIT. ENT. NAT. HIST. SOC., 1978 115

Ichneumonidae) bred 15.viii.1977 by Mr. R. Cordell, from a full-grown
larva of Eupithecia pulchellata Stephens found at East Prawle, Devon,
June 1977. In common with other members of this sub-family the Ichneu-
moninae, pulchellatus attacks the full-grown host or pre-pupa but emerges
from the host’s pupa. All the species are solitary parasites. Perkins (1960)
writes of the species being ‘infrequent’ in occurrence: possibly it is limited
by the distribution of E. pulchellata, apparently its only host. The exhibitor
was grateful to Mr. Cordella for the gift of the specimen.

E. S. BrapForD — (i) Gelechia scotinella H.-S., an uncommon moth
found among other micros in a box and recently confirmed as this species.
The larva feeds in the flowers of blackthorn in April, the adult moth
appearing in June-July. (ii) Pyralis farinalis L. bred from original wild
stock taken in Kent. There is a marked difference in the size of the two
broods that occurred in 1977. The food supply was plentiful, so there
must have been another cause for the smaller size of the second brood
specimens. The moth is usually single brooded; at times taking two years
to complete the life-cycle.

S. N. A. Jacops — A leaf of an American poplar bearing the gall and
mine of the Nepticulid moth Ectoedemia populella Busck, together with
drawings of the mine and also of the mine and gall made by the British
moth Ectoedemia turbidella (Z.) for comparison.

MEMBERSHIP
The obligation book was signed by Messrs. Cumming, Tranter and
Smith.

COMMUNICATIONS

Mr. E. S. BraprForpD reported that in his 1976 light-trap material he
had found two broods of the moth Stenoptilia saxifragae Fletcher (Lep.,
Pterophoridae), in fact 39 specimens of the first (vi-vii), and 10 specimens
of the second (viii-ix) at Boreham Wood, Herts. The species was first
found in Dublin nearly forty years ago.

Mr. K. G. B. SmitH then gave the Society a very comprehensive yet
succinct illustrated talk on ‘Changes in the British Diptera fauna’. This
was followed by a keen discussion on the many interesting aspects of the
subject.

OBSERVATIONS ON EXHIBITS
Some members reported having observed in the wild a second brood of
fyralis farinalis, while others declared they had never observed this.

23rd February 1978
The President, Mr. G. Prior, in the chair.

EXHIBITS

J. BRown — Two species of Lycaenidae from an isolated mountain in
.orthern Greece, recently discovered by the exhibitor and Mr. J. Coutsis,
sith transparencies illustrating the habitat. After performing chromosome
counts, the exhibitor was proposing to consider them as (i) a new species
near Lysandra coridon (Poda) and (ii) a new species of Agrodiaetus, subject
to reserves.

M. W. F. Tweepie — A photograph of the Arachnid Anelasmocephalus

The President then announced that two books had been presented to
the library, and exhibited them; they were Dragonflies of Great Britain
and Ireland (Hammond and Gardner), and Insect Photography (P. E.
Lindley).

NOMINATIONS

Having been read a second time, the following were declared elected
new members: A. R. Cronin, Lt. Col. G. Eastwick-Field, C. A. Guy, D.
Budworth, M.Sc., R. Allison, A.C.A., N. F. Heal and R. A. Softly.

COMMUNICATIONS

B. HarGREAVES then gave an illustrated talk on ‘The versatility of
entomological illustration’. In addition to revealing his own techniques and
showing some examples of early artists whom he admired, the speaker
showed reproductions of a mass of recent, unpublished illustrations. In
the ensuing discussion members were interested to learn the artist’s views
on various questions, such as the capacity of a non-entomological artist
to reveal diagnostic characters; the speaker said that for this purpose he
had had the benefit of repeated advice from entomological experts on the
groups concerned.

9th March 1978
The President, Mr. G. Prior, in the chair.

EXHIBITS

Dr. A. A. ALLEN — Two examples (¢, 2) of Dusona pulchripes
Holmgren (Hym., Ichneumonidae), bred singly from two larvae of Thera
obeliscata (Hiibner) (Lep., Geometridae). The hosts were beaten, in the
company of others, from low branches of Pinus sylvestris, 14.viii.1977, on
Haldon Moors, near Dawlish, Devon. The larvae attained full size at
irregular intervals, the majority producing moths in the early autumn.
The two parasitised by pulchripes were characteristically killed as pre-
pupae; one in late August, from which a @ was bred 18.ix.77, and one on
27.ix, the Q being bred 28.x. Not only is T. obeliscata a new host for the
parasite, but this record seems to represent the first incidence of pulchripes
in Britain. The exhibitor was compelled to send the insect to an authority
on Dusona, Dr. R. Hinz, in Germany, who kindly identified the species;
it was not in the British section at the British Museum, nor listed in the
(1945) Kloet & Hincks check-list. On the Continent the species is a parasite
of Thera juniperata (L.). It is possible that the species was introduced
when conifer trees were imported from Scandinavia and planted in
Britain.

L. N. Baxter — Actias maenas (Doubl.), an example of the adult
(Lep., Saturniidae), the larva of which was reared wholly on sumach
(Rhus typhira) after the third instar; the rearing was started on a mixture
of walnut (Juglans) and sumach, the latter by accident; it showed a
strong preference for this instead of the recommended walnut. The ova
were purchased from R. N. Baxter of Wanstead, and the adult hatched

COMMUNICATIONS

Dr. C. G. M. DE Worms reported that, after the severe cold spell, fair
numbers of moths had now appeared, among those reported being Biston
strataria (Hufn.) and the common Orthosia spp. Dr. ALLEN stated that the
first Gonepteryx rhamni (L.), a @ at Coulsdon, Surrey, was seen on
23rd February. Mr. E. WILD stated that he had so far only seen Apocheima
pilosaria (D. & S.) and Alsophila aescularia (D. & S.) to his light in
Surrey.

Mr. A. E. Srupss stated that the Nature Conservancy had declared
530 acres of the Wyre Forest, in Hereford and Worcestershire, as a
National Nature Reserve by agreement with the Forestry Commission.
Mr. M. Brown reported that Darenth Wood, Kent, considered by the
Nature Conservancy as a site of National Importance was under threat of
being quarried and subject to an enquiry in April. He had a list of old
records of Lepidoptera, but would be grateful for a list of species still
inhabiting it which might be endangered.

Dr. B. J. MacNutty then gave an illustrated talk on West African
Lepidoptera early stages; this one dealt particularly with Acraeidae, Lycae-
nidae and Hesperiidae.

NOMINATIONS

Their names having been read for the second time, the following were
duly declared elected members: Messrs. G. G. Cleland, M.Sc., A. J.
Halstead, M.Sc. and T. C. Rednall. The Rev. S. C. Pettis and Mr. M.
Sterling signed the obligation book.

COMMUNICATIONS

Dr. C. G. M. DE Worms reported that three examples of Gonepteryx
rhamni (L.), the brimstone, had been seen recently near Staines. In Dorset
Orthosia munda (D. & S.) had been noted as plentiful near Ringwood,
with Biston strataria (Hufn.) still on the wing, but Achlya flavicornis
(L.) was scarce; the first Yylocampa areola (Esp.) had been noted. Mr. R.
FAIRCLOUGH reported an unusually early appearance of one Thera variata
(D. & S.).

A discussion on ‘Conservation, help or hindrance to entomologists?’
then ensued, led by Mr. A. E. Stubbs, a member who is also one of the
Nature Conservancy staff. He said that entomologists, if they wished their
interests to be defended, should voice their concern, with details of an
endangered species’ place of flight, so that appropriate measures of
management could be taken before it became too late. Mr. John Rudge,
also of the Conservancy, spoke of the 1975 Act which at present forbade
under penalty the taking of Maculinea arion (L.), the large blue; he asked
members to state whether any of those present desired other species to be
named in future legislation. Nobody present suggested any other species
of Lepidoptera in need of protection in this way. However, a very animated
discussion on the topic of conservation as it related to this order and
other creatures, followed, and a variety of opinions, some critical of these
laws, were voiced.

EXHIBITS

Dr. A. A. ALLEN — (i) A @ Alexeter nebulator Thunberg (Hym.,
Ichneumonidae), caught at m.v. light at Plaistow, Sussex, 17.vii.1976. The
species is apparently very widely distributed but perhaps rather irregular
in its appearance. Most genera of the tribe Mesolerini (of the Ctenopel-
matinae) to which Alexeter belongs, are endoparasites of Symphyta larvae.
However, no reliable host records appear to exist for nebulator. It shares
with the following exhibit the ‘Ophionoid facies’, i.e. a testaceous colouring
and nocturnal flight, inter alia. (ii) A Q@ Ophion minutus Kriechbaumer
(Hym., Ichneumonidae), captured by Mr. P. Cordell, 20.v.1974, in a light
trap at Nutfield, Surrey. Ophion species are solitary endoparasites of
Lepidoptera and usually of large size; the present species may be recognised
by its small size and wing venation. Although widely distributed through
Southern England, it does not seem to be common, and is much rarer in
northern counties. (iii) Two larvae of Euplagia quadripunctaria (Poda)
(Lep., Arctiidae) (Jersey tiger) found on cliffs at Dawlish, Devon, 1 and
2.iv.1978; one larva was found at night feeding on groundsel, while the
other was beaten from bramble nearby, by day. Both were about lin. long
when captured. Although the moth is abundant at Dawlish in August,
these larvae were hard to find; but larvae of the scarlet tiger (Callimorpha
dominula (L.)) were abundant on nettle on the cliffs in late March and
early April 1978. (iv) A specimen of Phlogophora meticulosa (L.) (the
angle-shades moth) captured at 18.00 hours on 13.iv.1978 at South Audley
Street, London.

Mr. E. S. BRADFoRD — Eudonia angustea (Curtis) (Lep., Pyralidae). The
larvae of this species were found feeding on moss on walls in Faversham,
Kent. In 1977 the larvae were numerous on these same walls, almost
completely destroying the moss by their workings; however, the species
reappeared this year.

Mr. and Mrs. T. G. HowartTu exhibited three larvae, in their last instar,
of Euplagia quadripunctaria (Poda), bred from ova laid by a female
captured in Seaton, E. Devon, in August 1977, the easternmost station
of the moth in Britain. These having been reared indoors, were much
more advanced than those shown by Dr. Allen.

J. MuGGLETON — Morphs of the two-spotted ladybird (Adalia bipunctata
(L.)) (Col., Coccinellidae) commonly found in Britain, together with one spe-
cimen of the form fasciatopunctata of this beetle; examples of the latter
form have been found in 1976-77 at Staines, Datchet and Milford, though
apparently previously only known from Mongolia where it makes up over
50% of the population. Breeding experiments with the Staines form
indicate that fasciatopunctata is controlled by an allele recessive to the
typical form. The reason for its sudden appearance at Staines is a mystery.
It will be interesting to see whether the frequency increases in the next
few years.

MATTERS ARISING FROM THE LAST MINUTES
Mr. A. E. Stuspss spoke regarding the passage of Lord Cranbrook’s Bill,
reported to have been recently ‘nodded through’ its third reading in the
House of Lords. It is still not known whether the contestable portions
will still be in the Bill when it reaches the House of Commons. Dr. C. G. M.
DE Worms said he understood Lord Cranbrook had agreed to drop his
long list.

and Pinhey: ‘The Butterflies of Central and S. Africa’.

Mr. G. ELseE announced that, Dr. J. Alison having died, it would be
necessary to organise a substitute to speak at the meeting of 8th February
1979.

Mr. D. STIMPSON mentioned reports of tidying up Hampstead Heath
resulting in protests. Mr. SoFTLy said he understood that the Parks Depart-
ment had cleared scrub in the Old Kenwood Estate or Highgate Valley
sector. It was hoped that someone knowledgeable in conservancy would
be associated with these measures. The President undertook to find out
if such were the case.

COMMUNICATIONS

Dr. C. G. M. DE Worms reported that Celastrina argiolus (L.), the holly
blue, had been reported on the wing at Brighton, and that Lithophane
semibrunnea (Haworth) had recently visited his own light trap in Surrey.
Dr. ALLEN described the comparative frequency of larvae observed feeding
at night in March-April recently in Devon. Mr. R. Tusss reported that
hibernating larvae were about a fortnight late, 18 overwintering Limenitis
camilla (L.), white admiral, larvae only beginning to leave their hibernacula
on 8th April. Mr. G. ELse reported having, with Mr. D. Appleton, dug
out the rare beetle Anostris castaneus (L.) (Col., Elateridae) from sandy
hillocks on the southern coast-line of the Isle of Wight on 8th April
1978. Mr. MEREDITH reported the flight of Inachis io (L.), peacock, Aglais
urticae (L.), small tortoise-shell, and Polygonia c-album, comma, butterflies
on 3lst March in South Dorset, also the sighting of lizards and a badger.

Miss M. A. Grr_inc then gave an illustrated talk entitled: ‘Evidence
from fossil assemblages of Coleoptera of extinctions from the British
Fauna during the last 9,000 years’. Those present evinced great interest
in the data and conclusions revealed in this unusual talk, and the hope
was expressed that much of this might shortly be published in the Society’s
Proceedings.

EXHIBITS

Dr. A. A. ALLEN — A cocoon, alive and unhatched, of Apanteles
formosus Wesmael (Hym., Braconidae) obtained from a larva of Ourap-
teryx sambucaria (L.) (Lep., Geometridae) beaten from privet, 24.iii.1978,
in a wood at Salfords, Surrey. The host fed well on privet but did not
increase appreciably in size, and on 15.iv the parasite larva appeared and
spun its most characteristic cocoon near by to the dying host. The cocoon
was finally a rather discoloured yellow, but the outstanding feature was
the firm, thin stem which extended from the base of the cocoon to the
floor of the container for a distance of about 10mm. Shortly after the
parasite had appeared (from the rear half of the host), the host experienced
a series of violent convulsions, after which it died; it was dead within
twlve hours. This behaviour contrasted with the more usual gradual

120 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

deterioration of the host after the appearance of other solitary spp. of
Apanteles; in the experience of the exhibitor, death usually takes 3-6 days.
The host record is of interest for A. formosus has a known life-cycle: it is
bivoltine, the usual overwintering host larva in which A. formosus hiber-
nates is Abraxas grossulariata (L.), while the summer brood larva are
parasitic on larvae of Lycia hirtaria Clerck. Very old records list sambucaria
as a host, but G. T. Lyle, an experienced hymenopterist, failed to obtain
this species from the many sambucaria which he collected in the early part
of this century.

Lt. Col. A. M. Emmer — A larva of Epinotia nanana (Tr.) (Lep., Tortri-
cidae) mining leaves of Norway spruce (Picea abies), to show the unusual
method of feeding. The larva was taken in Hatfield Forest, Essex on
23rd April 1978.

G. Prior — (i) A ‘Handylite’ to which a fluorescent tube had been fitted
after purchase for £4.59, which can be hung from a tree and run from a
car battery to catch moths. (ii) Larvae of the slender pug (Eupithecia
tenuiata (Hibn.)) which had been beaten from the catkins of a female
Salix caprea by a member, John Fell, at Hockwold, near Thetford.

MATTERS ARISING FROM THE PREVIOUS MINUTES

The President stated that he had made the promised enquiries about
work at Hampstead Heath, but the G.L.C. was not telling the Camden
Borough Council anything about it.

COMMUNICATIONS

Dr. C. G. M. DE Worms said it had been a ‘blackthorn winter’ with
only two nice days in the spring period. However, A. Harbottle had seen
Vanessa atalanta (L.) on 23rd April; and another member, Mr. Messenger,
had seen Odontosia carmelita (Esper) on a telegraph-pole. Mr. G. R. ELSE
reported having seen Pyrgus malvae (L.) on the wing on 23rd April, on
which day also Polygonia c-album (L.) had been seen at Wimbledon by
Mr. R. Tusss. Other sightings or captures of various lepidoptera species
were also reported.

Mr. R. S. GeEorGE then gave an illustrated talk entitled “Trying to
record the distribution of British fleas’, full of anecdotes and salt.

The President, Mr. G. Prior, in the chair.

EXHIBITS

Rey. D. J. L. AGassiz — An extreme aberration of Nymphula nym-
phaeata (L.) (Lep., Pyralidae) taken in 1971 by Mr. J. D. Bonny at Crews
Hill, Enfield, Middx. The forewings were almost unicolorous ochreous
brown with a darker subterminal line.

Dr. A. A. ALLEN — Examples of Apanteles spurius Wesmael (Hym.,
Braconidae) and an unidentifiable species of Mesochorus (Hym., Ichneu-
monidae) occurring together as parasite and hyperparasite, respectively, of
Biston betularia (L.) (Lep., Geometridae). The host larva was found when
about half-grown, on 4.ix.77 in a lane near Reigate, Surrey, on elm. On
10-11.ix, eight larvae of A. spurius appeared from the host and spun their
yellowish cocoons. Normally these hatch in the spring of the following
year, but on 28-30.ix four specimens of a Mesochorus sp. (2 and 3 @)
were bred, while the remaining four cocoons hatched at the expected time
in late April 1978, giving rise to A. spurius (2 and 3 @). The exhibit

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 121

was of interest because it illustrated only partial parasitism, exactly half
of the gregarious parasite A. spurius being themselves parasitised by the
Mesochorus. The female Mesochorus oviposits directly into some or all of
the Apanteles larvae contained in the B. betularia. The occurrence of
hyperparasites may be readily inferred from Braconid cocoons by the
appearance of the hatched cocoon. The Mesochorus (like other Ichneu-
monids) chew an irregular hole in the cocoon to make their exit, while the
Braconidae all make a more or less neat slice across the top of the
cocoon.

E. S. BrapForp — A larva of Monochroa palustrella (Douglas) (Lep.,
Gelechiidae), a very local species, taken from the rootstock of a plant
of Rumex crispus from Stoke, Kent, in 1978.

B. O. C. GarpINER — Larvae of the American hawkmoth, Manduca
sexta (Johan.), being reared on an artificial diet, the subject of his talk
later in the evening; they were thriving, but of an unusual bluish hue.

Col. D. H. STERLING — Two larvae of Lithophane léautieri Boisd., bred
from ova obtained from a female which came to light at Winchester on
22nd October 1977 and laid five ova before it died, of which only two
hatched. These fed up on a species of Cupressus. After three months
feeding they were only just lin. long. Also three larvae and an emerged
pupal case of Luffia ferchaultella (Stephens) (Lep., Psychidae), from the
bark of trees in the Denny Bog area of the New Forest, Hants. The
exhibitor’s son, M. J. Sterling, found a pupal case of this moth on Ist
April from which a female emerged on 10th April. On the 14th April
he and his son discovered over 50 larvae on lichens growing on pines,
birches and oaks. Two more females hatched, but so far no male. He
surmised that the Denny Bog population was parthenogenetic, as this
phenomenon has been remarked on in some Psychids.

A. E. Stusss — A fig which he had brought back from a holiday in
Corsica, together with wingless males of a wasp said to fertilise the
figs.

COMMUNICATIONS

Dr. C. G. M. DE Worms reported that recently in Sussex both the
orange tip and holly blue butterflies had been seen on the wing in numbers.
Mr. CHALMERS-HUuNT reported having bred an example of the grey form
of Eupithecia venosata (Fab.) from County Clare, West Ireland. In reply
to a query by G. Prior whether there was a case-bearing larva on juniper
in Britain, Lt. Col. A. M. Emmert replied in the negative and it was
suggested that a sloe Psychid might be the identity of the case-bearer which
Mr. Prior had beaten at Wendover (?) from an isolated juniper.

B. O. C. GarpINER then gave a talk, with illustrations, on the rearing
in his laboratory at Cambridge of various lepidopterous larvae on an
artificial pabulum obtainable from Harris Biological Suppplies, Old Nixon
Estate, Weston-super-Mare, Avon. This talk evoked the liveliest interest
among listeners.

EXHIBITS

Dr. A. A. ALLEN — A 6 Agrypon flexorium Thunberg (Hym., Ichneu-
monidae) bred from Drepana falcataria (L.) (Lep., Drepanidae). The nearly
full-grown host was beaten out of young birch, 16.x.1977, on Hackhurst
Downs, Gomshall, Surrey. The host pupated at the end of the month, and
the parasite emerged from the pupa of the host on 10.v.1978. The
exhibitor had previously exhibited A. flexorium, but this is apparently the
first time it has been reared in Britain from D. falcataria. (ii) A larva,
as a pre-pupa, of Epirrita dilutata (D. & S.) (Lep., Geometridae) found
on birch, 21.v.1978, in Reigate Priory, Surrey. The larva was of interest
because of the presence of two cream ova of an ectoparasite, probably
of the genus Nefelia, lodged on its thoracic segments. The ova were
expected to hatch shortly and the hymenopterous larvae would then
consume the host.

Mr. G. Prior — Larvae of Eupithecia inturbata (Hibner) from Acer
campestris at Medmenham, 22.v.1978, showing the dorsal colouring which
serves to distinguish this species from the larvae of Operophtera brumata
(L.) (winter moth) in its later stages.

COMMENTS ON PREVIOUS MEETING MINUTES

Lt. Col. A. M. Emmert stated that in England Luffia ferchaultella (L.)
was always parthenogenetic, though ¢@ @ were known from the Channel
Isles.

Mr. G. Prior stated that the record of Eucosma pauperana (Dup.),
from Thetford, Norfolk, on 5.v.1978, had by an oversight been omitted
from the minutes; the capture had been made by Mr. J. L. Fenn in his
garden light trap. From East Anglia the previous record had been that of
a capture on the wing on Fleam Dyke, Cambs. Mr. BRETHERTON stated
that he had searched the Surrey locality where Rosa canina was abundant,
and from which this moth had been previously recorded, in vain. Lt. Col.
A. M. Emmet also made statements regarding this moth in the later
communications, reminding members that the first British record had been
made at Darenth Wood, 1854. He had recently himself captured it on
Fleam Dyke, between 6.00 and 6.30 p.m., and he suggested that the time
of flight might be limited which would account for its elusiveness.

MEMBERSHIP
After the reading of their names for the second time, Mr. A. Valetta
and Dr. J. Feltwell were declared elected members.

ANNOUNCEMENTS
The President announced that Mr. Rudge had informed him that the
third reading of Lord Cranbrook’s Bill was not yet assured. With reference
to the letters written to Mr. Rudge in March and April by the Society
on this topic, the list of prohibited species was now reduced from 129 to
16. This short list included the heath fritillary and the chequered skipper
butterflies and three species of grasshopper.

COMMUNICATIONS
Dr. C. G. M. DE Worms had visited the Wye Valley where orange
tip butterflies were noted to be numerous. At light two species of moth
deserved mention: the typical form of Egira conspicillaris (L.), usually

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 123

the rarer of its two forms, and a number of Nola confusalis (H.-S.). He had
also had reported to him the abundance of the holly blue in Sussex, whence
also H. lucina (L.), Boloria euphrosyne (L.) and Leptidea sinapis (L.)
were reported as now out.

Mr. BRETHERTON reported no more than ten moths per night on the
average as coming to his moth trap in Surrey, though the variety of
species was good, to which Mr. E. WILDE reported that to his trap in his
part of Surrey an average of nine had been noted.

Mr. R. J. VANE-WricuT then gave an illustrated talk on the evolution
and biology of Danaid butterflies. This evoked great interest in those
present.

8th June 1978
The Vice-President, Rev. D. J. L. AGassiz, in the chair.

EXHIBITS
Rev. D. J. L. AGassiz — Larva of Cnaemidophorus rhododactyla
(D. & S.) on a wild rose bud.
Dr. A. A. ALLEN — Two specimens of Meteorus versicolor Wesmael

(Hym., Braconidae), both obtained from moorland near Dawlish, Devon.
A female was bred 27.viii.1977 from a cocoon found on heather, 14.vili.77,
and a male was bred 4.v.1978 from a larva of Lycophotia porphyrea
(D. & S.) (Lep., Noctuidae), swept, with others, 30.i11.1978 from heather
on the same stretch of moorland. When captured, the host larva was
about half-grown and grew fairly slowly until the parasite larva appeared
from within the host on 14.iv. For the six days immediately prior to the
appearance of the parasite larva, the host did not feed, a phenomenon
which the exhibitor had noticed with other larvae parasitised by Mefeorus
spp. (e.g. M. near fragilis Wesm., ex Nola cucullatella (L.)). The female
exhibited was unremarkable, but the male was an unusually dark example,
a character communicated to the exhibitor by Mr. T. Huddlestone of the
British Museum (Natural History), to whom he was grateful for determining
the species. A second very dark male was also bred 22.iv.1978 from
another L. porphyrea larva found at the same time.

Lt. Col. A. M. EMmet — (i) Eucosma pauperana (Dup.) (Lep., Tortri-
cidae): two specimens taken at Fleam Dyke, Cambs. on 14 and 17.v.1978.
(ii) Mompha propinquella (Stainton) (Lep., Momphidae): pressed/willow-
herb leaves (Epilobium hirsutum) showing the larval-mine; this is normally
confined to the underside of the leaf and not visible from above. The
leaves were collected at West Wickham, Cambs., 29.v.1978: also leaves
containing cocoons spun in the final larval mines. The cocoon, being
generally spun along the midrib, contorts the leaf conspicuously. These
leaves were collected at Little Baddow, Essex, 2.vi.1978.

A. J. HatsteAD — Examples of the black citrus aphid (Toxoptera
aurantii (Boy.) (Hem., Aphididae): the world’s only stridulating aphid. A
faint, high pitched sound is made when the aphids jerk their bodies up
and down in unison. They have a roughened area on the side of their
abdomen which is brought into contact with hairs on the hind tibia, and
this presumably produces the sound. It has been suggested that stridulating
is a defence mechanism against predators and parasites. At Wisley, however,
the colonies are heavily parasitised by aphid spp. by mid-summer.

The black citrus aphid is a pest of citrus, coffee, tea and cacoa in
tropical and subtropical regions. It was first recorded in Britain on camellias
near Flint, Clwyd, in 1928. It then disappeared or was overlooked until

124 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

1968 when thriving colonies were found at the Royal Horticultural Society’s
garden at Wisley, Surrey. Since then it has continued to occur at Wisley,
although only camellia is attacked. It can be found even in the winter in
small numbers on outdoor camellias, but peak numbers occur in late
May-June when the new shoots and leaves are colonised.

E. H. Witp — Cocoon of Psychoides verhuella Bruand (Lep.,
Tinaeidae) from Weston-super-Mare, on heart’s tongue fern.

MATTERS ARISING FROM PREVIOUS MEETING MINUTES
Dr. A. A. ALLEN stated that the Nefelia ova deposited on the larva
exhibited at the previous meeting had failed to hatch, perhaps because
infertile; the host had pupated successfully.

MEMBERSHIP

The following names were read for the first time: Messrs. J. K. Packer,
J. B. Jobe, I. McClenaghan and D. W. Yendall.

Dr. R. BLAcKMAN then gave an illustrated talk entitled ‘The puzzle of
the adaptable aphid’. Aphid life-cycles are renowned for their complexity,
largely because of all the terms that are used to describe the seasonal
succession of different morphs. Stripped of this burdensome terminology,
aphids can be seen to have evolved a variety of alternative reproductive
strategies, whereby they can exploit the short-term advantages of partheno-
genesis, but at the same time balance this with the long-term need to
retain sexual reproduction. Some of these alternatives and other related
aspects of aphid biology were explored in this talk, which provoked many
questions from the audience who thus evinced how much they had been
interested by it.

DISCUSSION OF EXHIBITS
In reply to a question, Lt. Col. A. M. Emer said that the cocoon of
Mompha lacteella (Stephens), which also fed on willow-herb, was, in
contrast to that of M. propinquella, almost impossible to find, perhaps
being formed later in the year.

22nd June 1978
The President, Mr. G. Prior, in the chair.

EXHIBITS

Dr. A. A. ALLEN — Four specimens of the gregarious parasite Apanteles
chares Nixon (Hym., Braconidae), obtained with seven others from a larva
of Colotois pennaria (L.) (Lep., Geometridae), beaten from oak, 30.v.1978,
on Brownsea Island, Dorset. During the late evening of 31.v eleven parasites
appeared from the nearly full-grown host, around which they spun their
pale straw-coloured cocoons, mostly arranged in one group held together
by a tough, woven silk. Ten adult A. chares emerged during the night of
5-6.vi; the remaining cocoon yielded a hyperparasite, also exhibited, of the
genus Mesochorus (Ichneumonidae). The bred series of chares included
one male, which is the first apparently known occurrence of this sex of
chares. Although the host is a common species, especially as a larva, the
exhibited parasite, A. chares, appears to be very uncommon; the first
known example was caught in 1941, and the only records prior to this are
1944 and 1961; in the latter year a series was bred, also from pennaria.
All were caught in Southern England; see G. E. J. Nixon, Bull. ent Res.,
65: 722 (1976). Writing in that journal, Dr. Nixon suggests that A. chares

PROC. BRIT. ENT. NAT. HIST. soc., 1978 1125

is closely related to the more commonly occurring species Apanteles
spurius Wesmael; great care is needed to differentiate between the two.
A short series of A. spurius (ex. Biston betularia (L.)) was also exhibited
for superficial comparison with chares.

Lt. Col. A. M. Emmet — A bird’s nest from a nest-box from Shadwell
Wood Nature Reserve, Ashdon, Essex, from which specimens of Tinea
piercella Bentinck were emerging. This moth species was added to the
British list in 1943 by S. Wakely and appears to have been recorded only
seldom since then. A second, very flimsy, nest from Colne Point Nature
Reserve, St. Osyth, Essex, from which no fewer than 71 Tineids emerged,
consisting of Monopis rusticella (Hubner) and Tinea trinotella Thunberg
in about equal numbers.

P. A. SoxoLtorr — An intersex form of Agrotis cinerea (D. & S.) taken
on a recent Society Field Meeting at Ranmore, Surrey, 27th May. The
moth is predominantly male, the left forewing being streaked with female
characters, and each hindwing having a wedge of black scales. Also cases
of Coleophora vibicella (Hiibner) collected by Mr. J. M. Chalmers-Hunt
from Botley Wood, Hants. In the absence of the normal foodplant, Dyer’s
greenweed (Genista tinctoria L.), the exhibitor had successfully transferred
the larvae to a potted ornamental species, Genista lydia, purchased from
a garden centre.

MATTERS ARISING FROM THE PREVIOUS MEETING MINUTES

Lt. Col. A. M. Emmet referred to his previous exhibit of Mompha
propinguella (Stainton). These on hatching had in fact proved to be a
mixture of M. propinquella and M. ochraceella (Curtis) and constituted a
new record of the feeding habit of the latter.

NOMINATIONS

Their names having been read for the second time, Messrs. J. K. Packer,
J. B. Jobe, I. McClenaghan and D. W. Yendall were duly elected members.
The obligation book was signed by Mr. I. McClenaghan and Miss Burton.

COMMUNICATIONS

Mr. G. Prior said that he had spent two weeks at Ambleside in the
Lake District and had there noticed extensive defoliation of bushes by moth
larvae, particularly of sallows by Opisthograptis luteolata (L.), the brimstone
moth. He also remarked that in the London suburb of Hampstead great
numbers of the Tortricid Cacoecimorpha pronubana (Hibner) had been
noticed flying on privet hedges. The same had been noted by Mr. S. A.
KNILL-JONES in Balham, another suburb. Lt. Col. Emmet remarked that
this moth’s first record in the British Isles dated only from this century,
since when it had been gradually spreading northwards. Other members
also spoke of its occurrence and its polyphagy, Mr. E. S. BRADFORD saying
it had been recorded in London on indoors aspidistra!

D. G. CHELMICK then gave an illustrated talk on our rarer British dragon-
flies (Odonata). Of the 44 species of dragonfly on the British list (Kloet
& Hincks), 21 are common, or locally so, three are very rare vagrants,
and three others probably extinct. The remaining 17 are either restricted
to particular habitats or even to a handful of localities. The talk centred
upon these species, considered on the basis of the habitats in which they
occur and with particular emphasis on the threats to those habitats and
the need for much more intensive study of the British Odonata fauna. The
audience showed its appreciation at the end of this interesting talk in the
usual way.

ANNOUNCEMENTS
The President reminded all members desiring to borrow slides to register
with Mr. S. Knill-Jones.

COMMUNICATIONS

Mr. R. S. Tusss who has been breeding the white admiral (L. camilla
nigrina) (Lep., Nymphalidae) from twenty ova, reported that the larvae
overwintered and F.2 imagines refused to pair, probably because of the
impossibility of a nuptial flight in captivity.

Lt. Col. A. M. EMMET again spoke about Eucosma pauperana (Dup.)
(Lep., Tortricidae), describing spinnings obtained on wild rose; it appeared
that the larva fed on the pericarp rather than on the ‘hip’. The Rev.
D. J. L. AGassiz reported that he had obtained over 100 spinnings on wild
rose from Royston; from some of these Archips rosana (L.) was obtained,
but there had been among them about ten E. pauperana, of which he
could later find little sign; it was a species that hid itself well.

Mr. E. P. WILTSHIRE mentioned that the British species of early moth
(Theria, Lep., Geometridae) would henceforth have to be called primaria
Haworth, the true rupicapraria (D. & S.) occurring in Europe but being
unknown from Britain; the latter had the forewing cross-lines more
convergent at the hind-margin. This had already been known in the
British Museum (Natural History) but now a Danish magazine had
published the distinction between the two forms. He secondly appealed
to members to follow the correct spelling of the eyeless grayling aberration

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 127

(Hipparchia semele ab. holanops Brouwer) as a persistent but erroneous
school of entomologists continued to spell it holonops. He also mentioned
the receipt in the British Museum of a dead noctuid larva from Africa
for identification, said to have been found in the faeces of the mountain
gorilla. He wondered if Mr. David Carter would be able to name the
caterpillar which looked like an internal-feeding caterpillar.

A discussion of the pronunciation of the name Haworth then ensued,
and a member reported that a relative of the entomologist Haworth stated
that his family had always pronounced it ‘Hayworth’.

Mr. T. G. Howartu reported having seen a 2 Polygonia c-album (L.)
(comma butterfly) ab. hutchinsoni on 13th July at Canons Park.

Mr. CHALMERS-HunT reported than on 30th June at Ranmore, near
Dorking, he saw some Lysandra bellargus (Rott.), of which one male was
in mint condition.

Mr. BERNARD D’ABRERA then gave an illustrated talk on ‘Photographing
Birdwing Butterflies by available light’. He preferred to use Ektochrome
film in the tropics; he disliked using flash on living specimens. He described
the rapacious collecting and corrupt governments or wardens of some of
the states where these butterflies flew; owing to these, and deforestation in
some areas, he was gloomy about the future of Ornithoptera.

Many questions put to the lecturer by the large audience showed their
appreciation of his subject.

OBSERVATIONS ON EXHIBITS

Mr. CHALMERS-HunrT said that although Eupithecia insigniata had been
bred before from the ova, the larva had seldom been found before in the
wild state, to his knowledge. Mr. Prior said he had found them in the
Chilterns in a ride where old hawthorn and crab-apple were abundant,
also maple. Dr. C. G. M. DE Worms said that the moth had been taken
in apple orchards in the south of England.

FIELD MEETINGS
WESTBERE MARSHES, KENT — 9th July 1977
CHURCH WOOD, KENT — 10th July 1977
Leader —T. W. HARMAN

Five members joined the leader and the expedition started with a
general survey of the lakes and marshes. A number of interesting plants
were observed, including Conium maculatum L. (hemlock) and Oenanthe
fistulosa L. (tubular water dropwort). Insects were rather scarce, though
some larvae were found spun in shoots of Artemisia vulgaris L. (mugwort).

More careful searching later in the day revealed a number of larvae of
Eupithecia valerianata Hibn. on the flowers and seeds of Valeriana
officinalis L. Their camouflage on the seedheads was particularly good.
In the same marshy area were a number of plants of Typha latifolia L.
(reedmace) and, as these showed signs of larval attack, they were split
down to reveal their occupants. Nearly all contained larvae or pupae of
Archanara sparganii (Esp.), with a few only of Nonagria typhae (Thunb.).
A vain search was made for larvae of Catocala nupta (L.) on trunks of
large willows.

128 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

After refreshments at the ancient hostelry nearby, a number of m.y.
lights and Heath traps were set up in some excellent sites right in the
marsh. Although the temperature was not high, the sky was overcast, but
results were rather disappointing, almost certainly due to the late season.
A few Macrochilo cribrumalis (Hibn.), Mythimna obsoleta (Hubn.), M.
straminea (Tr.), and a fresh Spilosoma urticae (Esp.) were among the less
than 40 species of macrolepidoptera seen.

One member supplied a list of Hemiptera-Heteroptera, of which
Sthenaris roseri (H.-S.) and Calocoris sexguttatus (F.) were worthy of note.
Our lone micro-lepidopterist observed 14 species, of which Microthrix
similella (Zincken) was of particular interest.

The leader collected several species of Trichoptera from the various
lights. Among 12 species since identified was a specimen of Grammataulius
nitidus (Mull.), a local species only once previously observed in Kent, at
Deal in 1888.

From our observations it is obvious that this area has great potential and
further visits should be rewarding.

On Sunday the leader and one member visited Church Wood to ascertain
the status of Mellicta athalia athalia (Rott.). Although the foodplant was
abundant over large areas, the butterfly was in small numbers and very
local, and obviously not fully out in this late year.

SWANAGE, DORSET — 16th/17th July 1977
Leader — Mr. P. J. BAKER

The second meeting of the year to the Durlston County Park was not
well attended as only two members and a guest turned up.

The afternoon was pleasantly sunny but a persistent on-shore wind
restricted flight activity. Nevertheless, Maniola jurtina (L.), Coenonympha
pamphilus (L.) and Polyommatus icarus (Rott.) were flying freely and a
number of Clepsis consimilana (Hibn.), Eucosoma fulvana (Steph.), Pem-
pelia dilutella (Huibn.) and Agapeta hamana (L.) were flushed.

A feature of the area was the profusion of those flowers which are
characteristic of chalk/limestone areas. Especially abundant was Anacamptis
pyramidalis, the pyramidal orchid, with the occasional Ophrys apifera, the
bee orchid.

Examples of both M. jurtina and C. pamphilus were found with orchid
pollonia adhering to their proboscides. This must surely have been causing
the affected insects some inconvenience as they were unable to completely
retract these organs.

Towards dusk patches of Ononaria spp., the rest harrow, were found,
over which the plume Marasmarcha lunaedactyla (Haw.) was swarming in
very large numbers.

Due to the persistent breeze, which was south-westerly, lamps were sited
on the footpath and cliff edge adjacent to the Castle Hotel. These gave
very good results and turned up a number of interesting insects: Ancylis
achatana (D. & S.), Archips podana (Scop.), Crambus perlellus (Scop.),
Chrysotenchia culmella (L.), Ebulea crocealis (Htbn.), Aphomia sociella
(L.), Dioryctria abietella (D. & S.), Gastropacha quercifolia (L.), Malaco-
soma neustria (L.), Thyatira batis (L.), Habrosyne pyritoides (Hufn.),
Pseudoterpna pruinata (Walker), Hemithea aestivaria (Hubn.), Jodis

FEATHERBED LANE, ADDINGTON, SURREY — 25th July 1977
Leader — J. M. CHALMERS-HUNT

Sixteen people attended this meeting despite a poor weather forecast.
But the weather turned out not at all bad: it kept dry; for much of the
meeting, the wind was light and there were sunny spells about mid-day.

Many of those in the party were microlepidopterists who had hoped to
take the beautiful and very local Tortricoid Cochylis flaviciliana Westwood,
of which this is a noted locality. However, in this exceptionally late season
we were perhaps a fortnight too early as none was seen, though one was
taken here about a week later.

Several interesting lepidoptera were recorded, among which may be
mentioned: Ostrinia nubilalis (Hb.), Homoeosoma sinuella (F.), Aethes
hartmanniana (Clerck) (fairly numerous), Stenodes straminea (Haworth),
Reuttia subocellea (Stephens) (among Origanum vulgare), Stephensia brun-
nichella (L.) (mined leaves of Calamintha clinopodium) and Nemophora
scabiosella (Scopoli) (a number on flowers of Knautia arvensis).

Several species of butterfly were noted, including Argynnis aglaia L.
(dark green fritillary), Strymonidia w-album Knoch (white-letter hairstreak)
and Aphantopus hyperantus L. (ringlet).

Mr. Paul Sokoloff observed a slow worm which, according to Mr. Wild,
is very seldom seen in this locality.

ELLENDEN WOOD, near WHITSTABLE, KENT — 31st July 1977
Leaders — Mr. M. J. NEwcomee and Mr. E. S. BRADFORD

The leaders, the last to arrive at the meeting place, were greeted by
eight members who had already noted several species of lepidoptera,
including: Coleophora limosipennella (Dup.), Teleiodes vulgella (Hibn.),
Pyronia tithonus (L.) and Maniola jurtina (L.); the last two species jostling
each other at bramble flowers. Larval cases of the rather local Coleophora
limosipennella appeared to ‘be in some numbers on the scrubby elms
bordering the wood and road verges at Denstroude.

Various areas in Ellenden Wood were visited and numbers of insects
seen or taken. One small clearing produced two interesting species, viz.
Anana funebris (Strom). and Capperia britanniodactyla (Gregs.), as well
as Paltodora cytisella (Curt.), a number of which were taken by members.
Along one ride several specimens of Quercusia quercus (L.) could be
picked from the leaves of the trees, so lethargic they appeared.

Larval mines of Stigmella basiguttella (Hein.), Stigmella malella (Staint.),
Nepticula marginicolella (Staint.), Ectoedemia pulverosella (Staint.),
Tischeria ekebladella (Bjerk.), Tischeria marginea (Haw.) and Mompha
raschkiella (Zell.) were seen, some being taken for pressing. Larval cases
of Taleporia tubulosa (Retz.) and Psyche casta (Pall.) turned up occasionally
on the trunks of trees and bushes. Three micros of interest taken during
the day were Recurvaria nanella (D. & S.), Epinotia (Evetria) demarniana
(F.-R.) and Phalonidia curvistrigana (Staint.), all fairly local. Other Lepi-
doptera either seen or taken were: Bucculatrix ulmella (Zell.), Parornix
betulae (Staint.), Callisto denticulella (Thunb.), Phyllonorycter corylifoliella
(Hiibn.), Argyresthia brockeella (Hiibn.), A. goedartella (L.), A. curvella
(L.), Ypsolopha nemorella (L.), Ypsolopha parenthesella (L.), Plutella
xylostella (L.), Coleophora hornigi (Toll.) larval cases, Batia lunaris (Haw.),
Borkhausenia fuscescens (Haw.), Carcina quercana (F.), Byrotropha terrella
(D. & S.), Sorhagenia janiszewskae (Riedl.), old feeding sites in shoots of
buckthorn, Cydia fagiglandana (Zell.), Cydia janthinana (Dup.), Spilonota
ocellana (D. & S.), Epiblema uddmanniana (L.), Zeiraphera isertana (F.).
Ancylis mitterbacheriana (D. & S.), Olethreutes lacunana (D. & S.), Clepsis
consimilana (Hibn.) Cnephasia incertana (Treits.), Aleimma loeflingiana
(L.), Acleris emargana (F.), Crambus perlellus (Scop.), Agriphila straminella
(D. & S.), Agriphila tristella (D. & S.), Eudonia mercurella (L.), Endotricha
flammealis (D. & S.), Pieris brassicae (L.), Idaea biselata (Huf.), Lomaspilis
marginata (L.) and Scotopteryx chenopodiata (L.). Towards the end of the
meeting an interesting Eucosma was taken, which proved to be another
local species, Eucosma aemulana (Schlager).

Mr. M. J. Newcombe spent a busy day and recorded the following list of
Hemiptera-Heteroptera: Anthocoris nemorum (L.), Calocoris norvegicus
(L.), Dicyphus epilobii (Reut.), Elasmostethus interstinctus (L.), Halticus
apterus (L.), Heterotoma merioptera (Scop.), Kleidocerys resedae (Panz.),
Leptopterna dolobrata (L.), Liocoris tripustulatus (F.), Mecomma ambulans
(Fallen.), Nabis rugosus (L.), Orthotylus virescens (D. & S.), Phytocoris
tiliae (F.), Pithanus maerkeli (H.-S.) and Plagiognathus arbustorum (F.).
H. apterus (L.) and M. ambulans (Fallen) were two of note, the rest being
common or abundant.

DUNGENESS, KENT — 10th/11th September 1977
Leader — Mr. P. J. BAKER
Four stalwart members turned up at the venue, to be greeted with gale
force winds which prevented almost all flight activity both by day and
night.

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 131

Large numbers of Pieris rapae (L.) and P. brassicae (L.) were seen
sheltering from the wind, possibly the results of a migration or possibly
locally bred as Crambe maritima (L.), the sea kale, was abundant every-
where.

A small bag of the flower heads of Achillea millefolium (L.) was
collected in the hope that larvae of the pug Eupithecia millefoliata (Ross.)
would be found. An intensive search over the whole area for Linaria
vulgaris (Miller) produced not a single plant, which possibly bodes ill for
the present status of Calophasia lunula (Hufn.) in the area. The only
results from the search was a single larva of Smerinthus ocellata (L.) and
a number of Agriphila geniculea (Haw.).

A little before dusk a pleasant few minutes were spent searching the
toilets (male) in the Britannia Inn. This produced Noctua comes (Hiubn.),
C. geniculea, Mesapamea secalis (L.) and Xestia xanthographa (D. & S.).

At dusk sheets were laid and anchored with copious gravel in the lee of
some sallows. Little came to the lights, however, and an early night was
enjoyed by those present. Additional species at light: Agonopterix nervosa
(Haw.), Agrotis ipsilon (Hufn.), A. puta (Hiibn.) and Phlogophora
meticulosa (L.).

DANBURY, ESSEX — 30th October 1977
Leader — A. M. EMMET

The meeting was attended by twelve members in fine, mild weather. The
area worked was one of mixed woodland extending between the parishes
of Little Baddow and Woodham Walter. Interest centred on spinnings on
Norway spruce, believed to be those of Pulicalvaria piceaella (Kearfott)
which had been taken there as an adult earlier in the year; they were
plentiful enough, but many were vacated. Leaf-mines were collected from
oak, beech, birch, hawthorn, apple, species of sallow, aspen and wild
service-tree; those on the last foodplant were suspected to be of Phyilo-
norycter mespilella (Hubn.), which is known to occur in the area. Some
excitement was aroused by a P/yllonorycter mine on aspen, but as no
other could be found it was concluded that it was an example of xenophagy
and not the recently discovered P. sagittella (Bjerkander).

Another puzzle was an Elachista larva feeding in the leaves of the
rare sedge Carex laevigata (smooth sedge); the larvae were too small to
offer much prospect of successful rearing and another visit to the locality
in spring will be necessary to establish their identity. One of the less
common Nepticulids to be collected was Ectoedemia intimella (Z.) which
was found mining Salix fragilis, as well as C. caprea and S. cinerea.

Few adults were observed, but Diurnea phryganella (Hiibn.) was not
uncommon in the more open parts of the woodland. In the afternoon
R. and A. J. Fairclough broke away from the main party to beat for
Acleris cristana (D. & S.) in the neighbouring Backwarden Nature Reserve.
In addition to that species, they noted Ypsolophus notella (Clerck), Acleris
ferrugana (D. & S.), Epinotia maculana (F.), Epirrita dilutaria (D. & S.)
and Nyceteola revayana (Scop.).

SANDY DOWN, BOLDRE, HAMPSHIRE — 25th, 26th March 1978
Leader —R. W. WATSON
Once again Mr. and Mrs. Watson opened their house to members and

friends to view the Watson collection of British butterflies and larger moths,
now part of the National Collection.

132 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

There were 26 visitors on the first day and a further 15 on Sunday,
confirming the popularity of the meeting.

There were a number of new acquisitions among the butterfly varieties
to interest those who had previously seen the collection, and for those
for whom this was the first visit to ‘Porcorum’ the whole collection,
especially the butterfly and Arctiidae varieties, was of great interest.

Our thanks are due for the customary warm hospitality of Mr. and Mrs.
Watson and for the buffet lunch which Mrs. Watson and her helpers,
Jackie Dyke and Cathy Pickles, provided.

KINGSPARK WOOD, PLAISTOW, SUSSEX — 20th May 1978
Leader —K. G. W. Evans

This was a joint meeting with the Croydon Natural History and Scientific
Society and some 26 members and friends of the two societies attended
during the course of the day and night meeting at this delightful woodland
locality.

A severe challenge by a senior Forester points to the increasing need
for field meeting leaders to obtain the necessary permits to enter land
administered by the relevant authority. Fortunately, such a permit had
been obtained from the Forestry Commission, but without such it is clear
that the visit would have had to be aborted.

The day was warm and sunny and those attending had an enjoyable
time with most of the insects sought putting in an appearance. With the
season a little later than usual, the Wood White and the Broad-bordered
Bee Hawk were only just on the wing. Unfortunately, there was no sign
of our other quarry, the Drab Looper (Minoa murinata (Scop.)) and it is
probable that being a late season this little moth had not yet emerged.

In sharp contrast to a rewarding and pleasant day, the night was cold
and unsatisfactory. Although approximately 14 lights were operated, the
moth attendance was poor and nothing remarkable was reported.

Over the course of the meeting the following identifications were made:
LEPIDOPTERA: Erynnis tages (L.), Pyrgus malvae (L.), Leptidea sinapis

CURRENT LITERATURE
BOOK REVIEWS

Henry Doubleday, the Epping Naturalist, by Robert Mays. (Precision

Press, Marlow.) 118 pp., 3 plates. £4.20.

In his time Henry Doubleday was Britain’s great authority on Lepidoptera,
as well as no mean taxidermist, ornithologist and horticulturalist. Even
today, considering he hardly moved out of Epping all his life and was by
profession a grocer, his influence is unusually enduring; his collection of
Lepidoptera is housed in the British Museum, his techniques are still
followed to a great extent, at least three of his scientific pug-names are
still used and considered valid, and many of his more controversial opinions
have been vindicated. He was an original member of the Entomological
Society and was made a patron of our own Society in 1872. On his death
in 1875, the Society summed up his services to entomology as ‘of immense
value’ and added that ‘his invariable kindness had endeared him to all
who knew him’. Our present member, Robert Mays, in this handsome
little book, has collected and summarised his life, work, and background,
giving us also a fascinating picture of the naturalists and quakers in the
19th century and of a part of Essex now, alas, largely suburbanised. The
main section of the book is about 90 pages long and very easy to read;
it is followed by a 28-page appendix of notes and references with much
further matter of interest. Its appearance is timely as 1978 is the centenary
year of the Act which conserved for posterity Epping Forest, the scene
of Henry Doubleday’s birth in 1808, life, and death. I think none of our
members will regret acquiring, and all who do get it, will reopen it
frequently.

Baltic Amber —a Palaeobiological Study, by S. G. Larsson. Entomono-
graph, Vol. 1, 1978. Scandinavian Science Press Ltd., Klampenborg,
Denmark.

This interesting book, written entirely in good English, begins with a
section on amber itself, its stability, chemical and physical characteristics;

134 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

the next section deals with the origin of Baltic amber, and also shows the
location in the rest of the world of ambers as old or older than the Baltic,
and the relative position of the Continents at the end of the Cretaceous;
a third section deals with the world flora of the past, the flora found in
amber, the biological decline from the Eocene optimum and recent amber
floras. The fourth and longest section deals with the fauna of the amber
territory; it embraces virtually all orders of insects. A final section of ten
pages, entitled ‘Review’, summarises the whole and shows how the coni-
ferous plants, towards the end of the Palaeozoic, were the first to secrete
resin in large amounts. The greater part of amber known today is young
Cretaceous or early Tertiary. The formation of amber in the Baltic seems
to have stopped early in the Oligocene, somewhat later in Rhineland and
Roumania, but continued in Sicily into the Micocene, but the Pinites
‘amber’ forest had a much wider distribution in the world than this.
Chironomid fossils are especially abundant in ambers deriving from the
Scandinavian Pinites forest. The author endeavours to deduce ecological
conditions from the fauna of this amber prior to the destruction of the
fauna by the encroaching ice, as climatic belts were displaced towards the
equator. The fauna which postglacially replaced the Baltic amber fauna
consists mainly of purely boreal elements which during the Ice Age were
preserved in an Asiatic refuge. The original Baltic amber fauna appears
to be totally extinct.

All thinking entomologists interested by the palaeontology of their field
of study will find much stimulating food for reflection in this masterly
book, which inaugurates a new series designed to provide scope for larger
papers on entomological subjects. Following volumes announced are by
various English, American or Danish specialists, such as Gaden S.
Robinson and E. P. Wiltshire, from whom the publishers promise mono-
graphs on their specialities.

Butterflies on my Mind, by Dulcie Gray. Foreword by Sir Peter Scott.
Illustrated by Brian Hargreaves. Angus & Robertson (U.K.) Ltd., 16 Ship
Street, Brighton, Sussex; 123 pp., 30 coloured plates, other black and
white drawings, 10 maps. £5.75.

This book is addressed to the general British public. The authoress is a
writer of crime novels, children’s books and also an actress. However,
she is no newcomer to the subject of Rhopalocera, having been for ten
years Vice-President of the British Butterfly Conservation Society. The
artist, a member of our Society, whose work on butterflies most members
will know already, has been assisted by his wife in the lay-out of the
many striking pictures which mostly depict, in quite a new style, butterflies,
their foodplants and their habitats.

A strict biologist might protest that five scenes are unnatural, as they
show the butterfly on the plant, blooming, or in fruit, at a season when
the creature is not on the wing. This, however, would be rather unfair,
as the purpose of the pictures is to help the uninitiated reader to identify
both the butterfly and the foodplant, also in many cases to show the sort
of country they are found in, and not to represent what actually happens
when bug meets plant. Were the classical illustrators any more natural?

The text is a skilful tissue of the author’s own views, interwoven with
opinions of others; it should give pleasure and information to many.

PROC. BRIT. ENT. NAT. HIST. Soc., 1978 135

Quotations from old writers alternate with the utterances of doctors of
science or movie-stars; Miss Gray quotes not only Aristotle but has
consulted those now in the forefront of British entomological activity,
incidents from whose childhood are quoted with equal zest with what they
have to say on problems of ecology and conservation. There is quite a lot
by, or about Robert Goodden, and she assures us that his being an officer
of the Butterfly Conservation Society does not mean there is any connection
between it and his commercial butterfly farm, World Wide Butterflies,
Over Compton. This Society is indeed the one which she puts first among
five others which she recommends her readers to join (we are included! ).
In the chapter discussing the various enemies of butterflies, and in discussing
various cases of extinction in the present century, her attitude to the
collector, though not friendly, is not unreasonably hostile nor unbalanced.
In one passage she describes an exhibit contrasting the ancient and the
modern collector’s tools, at the Chequered Skipper Inn at Ashton Wold;
the modern collector is apparently well-off, for he is content with field
glasses, a camera with a zoom lens, a cine-camera, and electronic flash!
Her own views are summed up in the sentence: ‘there are now so many
excellent collections on exhibition, it seems silly to encourage people
without knowledge to pillage the countryside and make our environment
even bleaker . . . The fright butterflies receive on being caught must be
considered pain.’

We doubt whether, as claimed on the jacket, that this book will be ‘a
standard reference for every butterfly lover’, but even for the hardened
lepidopterist it contains a few useful passages, and for those unversed in
the lore of butterflies it would make a charming and informative present.
Sir Peter Scott’s foreword sums up in a dozen lines Dulcie Gray’s achieve-
ment; we consider she has performed the task she set herself most
successfully.

Libro rojo de los Lepidopteros Ibericos, by Manuel G. de Viedma and R.
Gomez Bustillo. (Instituto nacional para la conservacion de la Naturalezza,
Madrid, 1976.) 117 pp. No price stated.

The stated object of this book is to provide a basis for an adequate
policy of conservation for some of the lepidoptera of Spain and Portugal.
It covers 35 species of Rhopalocera and 15 Heterocera. These are classified,
with pages cornered in different colours, as ‘in danger of extinction’ (3),
‘vulnerable’ (8), ‘endemic’ (some of these are sub-species only) (13), ‘rare’
(19), ‘immigrant’ (5). Each species is well figured in colour photographs
and has a map of its present range in Iberia and brief accounts of its
life-cycle, the reasons for fears about its future, and recommendations for
further study of its habits. The text is in Spanish, but there is a one-page
explanatory summary in English.

The 35 Rhopalocera regarded as requiring some form of special attention
are about one-sixth of the total Iberian list. This may seem rather pessi-
mistic, in view of the fact that even the Rhopalocera of many parts of
Spain and Portugal are still little known, despite the considerable growth
of interest and recording, mainly by amateur collectors, in recent years.
The number is, however, swollen by the inclusion of almost all the
‘endemic’ species as a separate category. This is rather awkward, since, as
the text admits, some of these are widespread and common, while others
are probably in greater danger than some of the species classed as
‘vulnerable’; and, though it is certainly desirable to collect information

136 PROC. BRIT. ENT. NAT. HIST. SOC., 1978

about the ‘immigrant’ species, it is not clear what conservation could do
for them. The few Heterocera selected include only some diurnal
Zygaenidae, Graellsia isabelae and some other Bombycoidea, with two
introduced species, and two immigrant Sphingidae.

The recommendations for protection concentrate heavily on prohibition
of capture of the rarer species, followed by statements of the need for
more study of their biology and search for more localities for them to be
communicated to the appropriate authorities. There is very little mention
of the need for public or private action to protect their habitats from
agricultural changes or from massive afforestation such as are now taking
place in many known localities. While this attempt to identify and define
the needs for deliberate conservation of endangered species is to be
welcomed, one is bound to suspect that the recommendations for action are
likely to be more discouraging than helpful.

Guide des Papillons Nocturnes d’Europe et d’Afrique du Nord: Héterocéres
(Partim), by P. C. Rougeot and P. Viette. (Delachaux et Niestlé, Paris,
1978.) 227 pp., 40 colour plates. No price stated.

This book is presented as a successor to the French edition of the ‘Field
Guide to the Butterflies of Britain and Europe’, by L. G. Higgins and
N. D. Riley, which it follows closely in matter and textual arrangement.
It covers, however, only a small part of the European Heterocera, namely
153 nominotypical species and 59 additional sub-species in the Notodon-
tidae, Ctenuchidae, Lemoniidae, Brahmeidae, Saturniidae, Lasiocampidae
and Sphingidae. Nearly all these taxa are figured, most of them in both
sexes, by colour photography on an effective blue blackground. The texts
cover with admirable conciseness the French, and often other, popular
names for each species, its world range, description, season of flight, habitat
and foodplants, and European and North African distribution. There is a
well selected bibliography, mainly on a country and regional basis, but
also listing a number of recent taxomonic works; and a good check list
of the species covered, which does, however, lack synonyms.

Unfortunately, distribution maps have been omitted. The reason given,
that in the present state of the authors’ knowledge these would have
inevitably been very incomplete, seems to show some faint-heartedness; but
it is perhaps intelligible, since even for France the most recent collected
account of the distribution of Heterocera is L’Homme’s famous Catalogue,
of which the relevant part is more than fifty years old.

This Guide should be used by every British lepidopterist who collects on
the Continent, if only during his holidays; and we must all hope that the
authors will produce soon other volumes of similar excellence to deal
with other families of the Heterocera.

OUR CONTEMPORARIES

Bericht nat.-Med. Verein, 64 (Oct. 1977). Innsbruck.

On pp. 107-132 of this German-language periodical, not often consulted
by English entomologists, appears a most interesting article by Alois
Trawoger, entitled “Der Alpenwollafter, Eriogaster arbusculae Frr. Ein
Beitrag zur Kenntnis und Erforschung der Alpinen Schmetterlingsfauna’’.

This seems to have been evoked by a draft copy of part of the reviewer’s
article about the Swiss, French, and other European Small Eggar larvae
which appeared in full in our Proceedings, Vol. 10 (3/4): 98-99 (Pl. XII,

PROC. BRIT. ENT. NAT. HIST. soc., 1978 Si

fig. 1), sent to the author about a year earlier. Herr Trawoger, a resident
of Innsbruck, has had a 25-year long experience of these Eriogaster forms
in that district, and in the article now under review sums up his observations
and conclusions; consequently the article constitutes an important advance
in our knowledge of these moths.

The article deals with the deposition of the ova of the Alpine Small
Eggar, its larval stage, its pupation, its pupal period which lasts between
three and eight years (sic! ), the hatching of its imagines, which takes
place in 5-10 minutes during the daytime at the moment when the snow
recedes from the cocoon, the short mating flight (20-30 minutes) which
occurs just after sunset, and the mating (duration: 5-11 minutes). The
males live 6-8 days, the females seldom longer than a single day. There is
also a section on a hymenopterous parasite, and another on the variability
of the imagines. In captivity the author found it easy to obtain hybrid
couplings between arbusculae and lanestris, but impossible between ¢@ and
2 lanestris! The plates illustrate not only the life-history and the larval
form of arbusculae, but also hybrid larval and imaginal forms between it
and Janestris. Although the author obtained intermediates, he does not
consider the two forms necessarily conspecific.

Nevertheless, in a letter to me, kindly enclosing his article, Herr
Traw6ger informed me that he considered the Swiss Vissoie form which
I called the ‘southern form’ of larva and illustrated in Pl. XII, fig. 1b
(1977), as ‘lanestris under the influence of arbusculae’.

It would still be interesting to know whether this form occurs elsewhere
in Southern Europe, particularly if it occurs away from the high alps;
if this should be the case, its origin must be different from the suggestion
contained in Herr Trawé6ger’s letter. The latter’s article reveals him to be
the greatest authority on the E. Janestris group of our day and the
Innsbruck society have done science a service in publishing this important
article.

Lepidoptera (n.s. IID) (5) 1978/1. Copenhagen.

We quite recently drew attention to this excellent magazine and do so
again on account of the interesting articles in the above number which
will concern nearly all our readers, particularly the first article mentioned
below.

Michael Fibiger: “Theria primaria (Haworth 1809) (ibicaria (H.-S.) 1852)
found in Denmark’ is, we believe, the first actually to publish the correct
names, and give good illustrations, of the two Theria species inhabiting
Europe, hitherto confused. British collectors must henceforth cease to call
their Early Moths 7. rupicapraria (D. & S.) as in the new edition of Kloet
and Hincks. The males of the two species are easily distinguished in habitus,
for in true rupicapraria the cross lines are more convergent towards the
hind margin. I understand from D. S. Fletcher of the British Museum that
despite considerable search in various collections no example of rupicapraria
having been taken in Britain has been found, and there can therefore be
little doubt that Haworth’s name is the earliest for the one English species
which we all know. Fibiger’s artice shows the habitus differences and also
the differences in both sexes’ genitalia.

The same number contains a further article, also well illustrated, by
Henning Hansen entited ‘Aleucis distinctaria H.-S., new Danish moth’. If
new for Denmark, this moth, the Sloe Carpet, is not unknown, though
rather local in Britain; it is somewhat similar in appearance and biology
to T. primaria, and so its inclusion in the same number is very apt.

138 PROC. BRIT. ENT. NAT. HIST. Soc., 1978

Other articles include a good one by P. L. Holst entitled ‘Supplementary
Notes on Pyrausta ostrinalis Hibn.’ which presents a coloured plate of
this species and also of P. purpuralis (L.), P. aurata (Scop.) and P.
porphyralis (D. & S.). Male and female genitalia of these four species, also
a good plate of their undersides, accompany the text.

A fourth article on three Cochylidia species of Denmark completes the
number under review.

Entomops 46: June 1978.

In this number of our well-known French contemporary, the French
Noctuid Quadrifine specialist Dufay, evinces proof of wider lepidoptero-
logical interests, for his first article reports the occurrence in the Greek
mountains of Kaljakouda of some interesting butterflies and moths,
including Cyaniris helena Staudinger; Noctua haywardi Tams, hitherto
known from Cyprus, has now turned up in Macedonia and on Mt. Olympus;
and the eastern subspecies of Dendrolimus pini, namely cederensis Dan.,
proves to be, at least in the author’s material, the most widespread form
of this handsome Lasiocampid in Greece. A second article by Claude Dufay
deals with four Thera species, all of which he now shows to inhabit
France; these are T. variata D. & S., T. obeliscata Hiibn., T. stragulata
Hibn., and 7. albonigrata Gornik. The author illustrates the forms and
shows the structural differences in their antenna, genitalia, etc., and also
recapitulates their literary history. It constitutes a useful revision of the
group, only two of which are known from the U.K. as far as we know.

Other articles in the same number are by Balletto and Toso on Zygaena
minos D. & S. in the Ligurian Alps and G. S. Tempere and J. Giudicelli
on Coleoptera.

Nota Lepidopterologica 1 (2), 1978.

SEL (Societas Europaea Lepidopterologica) has begun to take its place
in the literature and other activities of British and Continental lepidop-
terists; last year its first puplication ‘Acta’ (the Hipparchia Revision reviewed
in our Proceedings, 10 (3/4): 122) appeared; and a Congress was held in
March this year in Paris. And now a second part of its ‘Nota’ has reached
us. This last is a plurilingual 48-page number with a scarlet cover and
contains articles under headings Faunistic, Genetic, Environment, respec-
tively by H. E. Back (Saharan Rhopalocera), E. Suomalainen (Partheno-
genesis of Nemophora) and G. Ebert (‘red lists’). There is also an
‘Autobibliography with an autobiographical note’ by B. C. S. Warren, the
first of a planned series of similar contributions, and some intelligent
unilingual reviews of contemporary publications.

The good paper and printing, and well-planned editorial policy, make this
magazine, which will doubtless appear more regularly and frequently than
the ‘Acta’, a welcome addition to Our Contemporaries, particularly as the
articles, if not written in English, contain résumés in English and another
European language. We recommend all British Lepidopterists, with an
interest in Europe, to subscribe to the Society (annual membership fee
D.M.20/-, entrance fee D.M.5/-); membership should certainly be higher
than 353, the latest published figure (1st March 1978). The cost of a single
number for non-members is D.M.8/-. Applications for membership should
be sent to the Membership Secretary, S. Wagener, at Hemdenerweg 19,
D-4290 Bockholt, West Germany.

The Society’s Publications
ILLUSTRATED PAPERS ON BRITISH MACROLEPIDOPTERA

The Society announces the publication shortly in one volume of twelve
articles reprinted from the ‘South London’ Proceedings between 1944 and
1957 with the twelve original colour plates.

These papers comprise LAMPRONIIDAE and ADELIDAE, LITHO-
COLLETIS and OECOPHORIDAE (three parts) and ALLIED FAMILIES
by S. N. A. Jacobs; PSYCHIDAE, PLUTELLIDAE and GLYPHIP-
TERYGIDAE and ALLIED GENERA by L. T. Ford; CALOPTILIA and
LYONETIIDAE by S. C. S. Brown; ERIOCRANIIDAE and MICROP-
TERYGIDAE by J. Heath and MOMPHA by S. Wakely. For ease of use
the pages and plates have been renumbered and are fully indexed
accordingly; in addition there is a new appendix drawing attention to
species belonging to these groups which have been added or sunk. There
is also a list of species which relates names used in the text to up-to-date
nomenclature and classification.

A limited edition of 500 copies is being published in the Autumn of
1978. The book will be bound in cloth. Price: £9; £6 to members of the
Society. Postage, where applicable, 60p extra.

Cheques should be sent to the Hon. Treasurer, R. F. Bretherton Esq.,

A LEPIDOPTERIST’S HANDBOOK

The Amateur Entomologist’s Society is pleased to announce the publication
of its latest Handbook, written by Richard Dickson. It is intended as a
‘vade mecum’ for both beginners and initiated lepidopterists and deals with
all aspects of the subject in a series of eleven chapters and four appendices.
There are 34 line illustrations and 13 photographs to augment the text
and the binding has been sewn to meet constant use.

It is a practical book on the various facets of breeding, collecting, storing,
conservation and photography of lepidoptera and should appeal to most
lepidopterists. Although the various techniques relate to the British fauna,
most are valid for lepidopterists anywhere.

The price is £3.00 plus postage and is available from A.E.S. Publication
Agent, 137 Gleneldon Road, London, SW16 2BQ. (An invoice will be sent
with orders, including postage.)

EDITORIAL

In recent years, the first double-part of these Proceedings has included
reports on both the Annual Exhibition of the preceding autumn and
the Annual General Meeting of January of the current year.

This year the Annual General Meeting on January 25th was adjourned
to a later date due to a combination of bad weather and transport strikes
affecting the attendance. We are, however, able to hold over the meeting
report (usually running to some eight pages) without reducing size, thanks
to one or two weighty constributions in hand. An early appearance is
very desirable for various reasons, mainly financial, and it is still our aim,
but a further snag may frustrate the hope: — our printers are trying to
catch up the time lost last autumn when a break-down set them back six
weeks in printing a monthly contemporary and our own Proceedings; may
they succeed!

These explanations will enlighten members who may not have received
the index to Vol. 11 or the reprints of their own contributions as promptly
as desired, or who may miss certain customary features in the present
double-part. As for our hope to appear as early as late March, more or
less emerging in step with the Brindled Beauty (Lycia hirtaria (Clerk)).
our readers, who are mostly lepidopterists and used to making allowances
for the vagaries of the weather or other forces majeures, will, we trust,
pardon us if, after all, we should not hatch before April.

THE 1978 ANNUAL EXHIBITION

(see Plates I, ID

The Society’s Annual Exhibition was again held at Chelsea Old Town
Hall on the day immediately following the Annual Dinner, Saturday,
October 28th. The attendance was good, and considering that the season
had been as unfavourable for insects as any could remember the total of
over 100 exhibitors was creditable, even if there was a slight falling-off
compared with last year. Of these over seventy were of Lepidoptera.

The Editor is indebted to Messrs. B. Skinner, R. Bretherton, J. Chalmers-
Hunt, D. Stimpson, G. Else and Dr. A. A. Allen for their reports on the
various classes of exhibits, and to Mr. D. Wilson for the photographs in
the Plates. Wholehearted thanks are also due to Mrs. Murphy for organis-
ing the refreshments and to members of certain members’ families for
assisting her in serving them.

FOREIGN LEPIDOPTERA

Some twenty members showed foreign lepidoptera, covering a wide range
of origins and interest. For Scandinavia there was a large display by Stic
TorsTENius and C. B. Asnpy of the collection of Geometridae and other
species which the former has generously given to the Society. This is now
being arranged and incorporated in our cabinets. It is of great interest as
a basis for comparison of the forms of species which are found in
Scandinavia and in Britain, and also as a guide to many species (47 among
the 248 Geometridae alone) which we are not known to have, and which
members may be tempted to seek in Scandinavia and possibly as new
discoveries in the British Isles.

From France, P. W. Crisp and R. W. Dyson showed selections from 130
species of Rhopalocera seen during a two weeks expedition from Calais to
the Parc National des Ecrins and the Montagne de Lure, and R. F.
BRETHERTON a case of eleven species of Erebia and some of the Zygaenidae
and nocturnal Heterocera from the same expedition; but the late season
inhibited study of high level species. Dr. C. LuckKENS showed butterflies
collected in the Var department in April and in Andorra July, and G. N.
Burton lepidoptera taken in the Cevennes from 13th to 16th August,
including Chazara briseis (L.), f. pirata Esp. and Lysandra coridon (Poda),
f. syngrapha Kef., and Amphipyra livida (D. & S.), a species allied to our
A. pyramidea (L.). He also showed lepidoptera from Sierra de Guadarrhama,
Picos de Europa, and Jaca, in Spain; and T. G. Homer comparative selec-
tions of Spanish species taken in the spring of 1978 and the early summer of
1974. Dr. C. G. M. pe Worms exhibted Melanargia (eight species) and
Plebicula (six species) from Europe and North Africa, and also Rhopalocera
caught in High Atlas of Morocco, 19th to 29th July 1978. G. Prior
displayed coloured illustrations of Eupithecia larvae from “Biologie der
Eupithecien” by Karl Dietze.

6 PROC. BRIT. ENT. NAT. HIST. soc., 1979

From the Middle East Guy Broome had 57 Rhopalocera species from
Turkey and Cyprus; and T. B. LarsEN showed examples, caught by the
British Ambassador in the Yemen in 1974, of Papilio machaon rathjensi
Warnecke, Pararge felix Warnecke, Lycaena phlaeas shima Gabriel, and
Carcharodus alceae wissmanni Warnecke, with a map showing the wide
separation of these species and sub-species from their nearest relatives.

From West Africa H. C. J. Goprray had various Syntomidae collectd on
the Oxford expedition to Mount Numba, Liberia in July to September 1978;
and from the Western Pacific G. S. and H. S. Rosinson illustrated the
spread and displacement in the Solomon Islands of species and forms of
Arctiid genus Utetheisa, familir to us as the rare immigrant U. pulchella.

Str Cyrit CLARKE and the Hon. MiriaAM ROTHSCHILD jointly exhibited
typical and mutant specimens of Danaus plexippus erippus Cr. reared
from Argentine stock, and a photograph of that species attracted to flowers
of the Orchid Epidendrum paniculatum by their scent: this mimics
pyrrolizidene alkaloids which are sequestered by the butterflies. Sir CyriIL
CLARKE also showed specimens of the Japanese Vapourer moth (Orgyia
thyellina Butl.): it is closely related to O. antiqua (L.), to which its females
will readily assemble. Finally, P. J. Crorr illustrated apparent Batesian
mimicry between species in unrelated families in Wenezuela, Trinidad,
Canada, Borneo, and Taiwan.

mespilella (Hbn.) had all been checked by genitalia. Particular note was
made of the last two, which are rare and local respectively and frequently
misidentified in collections. The feeding preferences of the species were
discussed, particulary in respect of cydoniella whose preferred foodplant is
Cydonia (quince) and whose distribution in UK is apparently very limited.
Among those exhibited were two P. cydoniella (det. I.A.W.), taken by S.
E. Whitebread at the Danbury, Essex 1977 field meeting ex crab apple.
The exhibitor requested supposed specimens of cydoniella and mespilella
for confirmation by genitalia preparation.

Darsy, M.—A display of books on the British Coleoptera published
between the late 18th to early 20th century, all from his personal library.
This was a rare opportunity to see such a range of rare classic works

from Martyn, 1792 to Fowler, 1887-1913.
Hopce, P. J.—A selection of interesting Coleoptera taken during 1977-
1978, including: Trechus rivularis Gyll., Dromius longiceps Dej. and D.
sigma Rossi from Yorkshire; Haliplus mucronatus Steph., Graptodytes
flapipes Ol., Anthicus bimaculatus Ill., Anthonomus brunnipennis Lat., and
Apion cerdo Gerst. from Sussex. The last named species is northern in its
British distribution, but is in fact quite a common and widespread species
in Kent and East Sussex, and has perhaps been confused with the closely
related species A. subulatum Kirby and A. cracce (L.). Also from Sussex
was Magdalis barbicornis (Latr.) a species rediscovered in Sussex. Leptura
rubra (L.) from the ‘Breckland’ of Norfolk (see Plate II, fig. 20): the
exhibitor has been unable to ascertain whether or not this species is of
regular occurrence now-a-days; there are no records that he can find since
the 1940s. Agabus striolatus Gyll., Hydroporus scalesianus Steph. and
Ceuthorrhychus querceti Gyll. from the Norfolk Broads.
Paary, J.A.—A selection beetles including: Emus hirtus (L) taken at
Canterbury in 1949, Dyschirius angustatus (Aherns) from sandhills at Rye,
Sussex 1974, and Thalassophilus longicornis (Sturm) from Betws y Coed in
July 1978.
Younc, M. R.— The distribution of three northern water beetles, Pota-
monectes griseostriatus (Degeer), Dytiscus lapponicus Gyllenhal and Gyrinus
opacus Sahlberg was illustrated, accompanied by specimens of each.
Although thought of as strictly northern, only G. opacus is exclusively
Scottish. All show the common pattern of lower altitudinal preferences at
higher latitude.

HYMENOPTERA

Etse, G. R.— Aculeate Hymenoptera collected in Dorset and Devon,
May-June 1978, in conjunction with an inauguaral field meeting of the
recently launched ‘Bees, Wasps and Ants Recording Scheme’. The twenty
species exhibited included two national rarities (both from Devon) — the
wasp Euodynerus quadrifasciatus (F.) (Eumenidae), &, and the bee Nomada
sexfasciata Panzer (Anthophoridae), 2 2 2 (known today from only one
site in Britain, but formerly widely distributed over southern England; it is
the inquiline of the bee Eucera longicornis (L.). Other Devon specimens
included: Vespula austriaca (Panzer) (Vespidae), 2, Stover Park, Near
Bovey Tracy, 28.v. (inquiline of V. rufa (L.);Andrena cineraria (L.)
Andrenidae). @, Rushlade Common, Dartmoor, 29.v. and 2 Man Sands,
Near Brixham, 31.v.; A. bucephala (Stevens), 2 2 2, and its scarce inquiline
Nomada hirtipes Pérez, 3 2 2, both species from New Bridge, Near Holne,
29.v.; A. labiata F., 8, Man Sands, 31.v.;Lasioglossum cupromicans Pérez
(Halictidate), 2, Corndon Down, Near Widecombe, 29.v. Dorset specimens
included: Andrena labiata,é 9, and Osmia bicolor (Schrank) (Megachildae),
2, both species from Chideock (Undercliff) 27.v. A second exhibit was
mainly devoted to aculeates collected in Hampshire and the Isle of Wight
during May-June 1978. These included: Andrena labiata, 2 2 2, Warsash,
Hans., 20.v. and, from the Isle of Wight, Argogorytes fargei (Shuckard)
(Sphecidae), ¢, Red Cliff, Near Sandown, 11.vi.; Andrena proxima (Kirby),
4 2, Steephill Cove area, Near Ventor, 13.v.; A. cineraria, 9, Apes Down,
west of Newport, 6.vi.; Osmia xanthomelana (Kirby), 2 2 2, coastal site,
11.vi. (formerly widespread as far north as North Wales and Lancashire,
but today the most recent records are from two sites on the Isle of Wight).
Another Hampshire specimen exhibited was Xylocopa violacea (L.) (Xylo-
copidae), 2, Cove, Near Farnborough, on the floor of a greengrocer’s and
florist’s, 16.1., H. Schonhut (the shop assistant). This large and striking bee
with an almost hairless black head and body and violet wings is a rare
vagrant to Britain, almost certainly arriving in imported timber and produce
from the Continent. It is a ‘Carpenter bee’, the female excavating nesting
galleries in timber.

PARASITIC HYMENOPTERA

Species of note included: Dusona pulchripes Holmgren, new to Britain;
bred ex Thera obeliscata (Hiibn.); Charops cantator de Geer (although
exhibited on a previous occasion, a new locality was described for this rare
species;) Apanteles chares Nixon; Rogas pulchripes (Wesmael) (the second
and third recorded British species) and a species of Holocremnus (Ichneu-
monidae) of intriguing interst (see below under SHAw, M. R.).

Once again the co-operation of Lepidopterists and other specialists, in
saving reared parasites and the host-remains, is gratefully acknowledged by
the two main exhibitors and is hoped that other entomologists will be
encouraged to follow their example.

ALLEN, A. A. — Firstly, an exhibit illustrating nocturnal species of para-
sitic hymenoptera — nearly all these species possess constant, superficial,
features, viz. —testaceous colouring, large occelli and elongate antennae
(Gauld, Ent. Gaz., 27, 35 (1976)). Species previously not shown, or of
especial interest were: Macroncentrus thoracicus (Nees), caught 11.viii.1978,
Holcombe, Devon, at m.v.l.; Charmon extensor L., —9.ix.1978, Plaistow,
Sussex, at m.v.l. This species is atypical of this group, since the colouring
is blackish —it seems fairly common, yet the host is unknown; Zemiotes
chlorophthalmus Nees (erroneously published earlier as Chrysophthalmus)
—two species: (22) from Reigate, Surrey, 28.vii.and Dawlish, Devon,
12.viii. both 1978, at actinic light; Nefelia cristatus Thomson, 92, taken at
m.yv.l., 9.ix.1978, Plaistow, Sussex (this genus — with that of Ophion — is
one of the commonest Ichneumonoidea at light) and Ichneumon deliratorius
L.— an anomalous species, for although quite common, it is very different
in appearance from the other noctural parasitica. The present specimen
came from Plaistow, Sussex —takenn at m.v.l., 9.ix.1978.

A second exhibit illustrated some bred British Apanteles species, their
host preferences, their various — sometimes characteristic — cocoon formu-
tion. The examples included: Apanteles inclusus Ratzeburg, from two
sources —a series bred from Euproctis similis Fuessly, at Lichfield, Staffs..

14 PROC. BRIT. ENT. NAT. HIST. soc., 1979

while the other arose from cocoons found by the exhibitor, 12.i.1974, on
an oak branch, Earlswood Common, Surrey. Although mostly empty, the
cocoons yielded a few intact species of inclusus, which seems to be difficult
to come across. The cocoon mass is formed in that of the host. A. limbatus
Marshall, bred from, and seemingly exclusively parasitic on, Abraxas
grossulariata (L). The series exhibited were from Camber, (host on Salix
alba 20.v.) and Littlehampton (host on Prunus spinosa, 19.v.) both in Sussex,
1978. In each case several larvae from each locality were affected — the size
of the brood varied from three to fourteen.

Lawton, F. D.— An exhibit consisting of an unidentified species of Meso-
chrous (Ichneumonidae) and the cocoon from which it had emerged,
namely the characteristic cocoon of Apanteles gonepterygis Marshall.

The genus Mesochorus are hyperparasites —the oviposits directly into a
parasite larva already contained in its own host. In this instance, the
primary host was Gonepteryx rhamni (L.) (LEP, Pieridae), three larvae of
which were collected in Ferndown Forest, Near Wimborne, Dorset, in June
1978. All three were parasitized by the host-specific gonepterygis,; a solitary
endoparasite. The host is destroyed before the full growth is attained and
the larva of gonopterygis then spins its curious, bright orange, cocoon on the
centre of which is a large, filamented, tuft of silk in a fan-like arrangement.

A Mesochorus sp. emerged from one cocoon in early August; the othef
two cocoons remained intact — probably the primary (Apanteles) parasite
would hatch in the Spring. (See Nixon, G. E. J. in Bull. ent. Res., 64,
465 et seq. and Wilkinson, D. S., Trans. Roy. Ent. Soc., 95, 95-98 (1945).

The exhibitor expressed his grateful thanks to Miss M. Brooks for pro-
viding the material and to Dr. G. Nixon and Dr. I. D. Gauld (both of the
B.M. (N.H.) for assistance in determining the identity of the insects.

Martin, P.— An example of Mesostenidea obnoxius Gravenhorst, bred
as a secondary parasite — from the cocoon — of a species of Z)gaena.
Apanteles plutellae, Kurdjumov — exhibited earlier in the year from
Noctua orbona, the exhibitor now showed individuals bred singly from a
more familiar host — Aglais urticae, L. The exhibitor had found many of
these larvae on Urtica in Dawlish Warren, Devon, 3.viii.1978 in various
stages of development, but of the many larvae taken, only the smalest (least
developed) larvae harboured the parasite — perhaps yet another example of
parastites slowing down the rate of growth of their host. Some of the adult
plutellae from urticae were bred in late August, and presumably seek
another host in which to overwinter as larvae (? e.g., Noctua sp.) but some
cocoons had not hatched by mid-December. A. immunis Haliday —a single
example bred in September, 1978, from an unidentifiable geometrid larva
swept from heater, 30.viii.1978 on Hankley Common, Elstead, Surrey.

Another exhibit consisted of a few adult Ichneumonidae taken in 1978.
Amongst the species were: Charops cantator, de Geer (9), taken 10.viii.
at Bugle, Cornwall; Heteropelma amictum Fab. (2), caught on the wing-
low down —at Tywardreath, Cornwall, 10.viii; Rhexidermus thoracicus
Gravenhorst (@), swept from laneside herbage, Shaldon, Devon, 7.viii;
Ichneumon validicornis Holmgren, 2, swept from very damp vegetation
along a stream at Tywardreath, Cornwall, 8.viii; Hepiopelmus leucostigmus
Grav. 2, swept by the sea at Littlehampton, Sussex, 27.viii; Barichneumon
ridibundus Grav. ¢, often taken in 1978 —the example shown was from
Plaistow, Sussex, 9.ix; B. monostagon Gravy., a @ from Shaldon, Devon,
7.viii; Amblyteles elongatus Brischke, 2, captured when flying low over

rough ground in fine rain at Bugle, Cornwall, 10.viii; and A. palliatorius
Grav., which although common, gave rise to a @ exhibit unusually heavily
marked with reddish-orange. It was captured flying around young pines on
Hankley Common, Surrey, 30.viii.

Crow, P. — A few representatives of a brood of an Apanteles sp. (later
det. as bignellii (Marshall; det. A. A. Allen) bred from Euphydryas aurinia
Rott. from a locality in Wales. The species is a notorious parasite of”
aurinia.

SHaw, M. R. — Examples of reared Ichneumonoidea of particular signi-
ficance, all bred in 1978. They included a part of an all-male brood of an
unidentifiable species of Holocremnus obtained as an endoparasite of
Cimbex femoratus (L.) (HYM. Cimbicidae) from Chat Moss, Manchester.
This was the only incidence known to the exhibitor of gregarious endo-
parasitism in the Ichneumonidae. Also with this exhibit were an adult of
the host sp. and an example of each sex of the common gregarious ecto-
parasite of Cimbicid cocoons, Agrothreutes mandator (L.) (Ichneumonidae,
Hemitelinae). Next, some rare British species of Rogas (Braconidae,
Rogadinae) were shown, amongst which were two specimens of R. pulch-
ripes (Wesmael) bred from ‘mummified’ larvae of Acronicta psi (L.) and
Acronicta tridens (D. & S.) (Noctuidae), both taken on Chat Moss, Man-
chester. Previously, the species pulchripes was only known in the British
Isles from a single female taken in Ireland, 193. Another species of Rogas
was R. rugulosus (Nees), two examples of which were displayed; they were
bred from Acronicta rumicis (L.) and A. menyanthidis Esper, both as a
result of induced parasitism in captivity. The parents were from Meathop
Moss, Cumbria; the species is also known in Wickham Fen and in an
Irish locality.

A third species of Rogas shown was R. praetor Reinhard, the single
example was reared from the larva of Mimas tiliae (L.) (Sphingidae) found
on Hampstead Heath, London as a ‘mummy’ by R. A. Softly. The species
is widely distributed in Southern England, but infrequently collected. Notes
on the species described above accompanied the exhibit; the exhibitor
appealed for reared parasites to be sent to him.

The exhibitor also showed the parasite complexes (primary and secondary-
hyper-parasites) of the host species Zygaena filipendulae (L.) and Leucoma
salicis (L.). The notes with the exhibit exjlained that the composition of
each complex was similar —a small number of more or less host-specific
primary parasites (e.g. Apanteles zyganarum Marshall on Zygaena sp. and
a larger number of secondary parasites, whose occurrence was opportunistic
rather than obligatory, by virtue of their far lesser host specificity. Many of
these latter are parasites of cocoons and are not encountered if the host
larva is collected. These hyperparasites play a large part in stablizing the
host-primary parasite interactions, helping to prevent large fluctuations in
the populations of both, which could otherwise lead to local extinction of
one or more of the species.

The exhibitor was of the opinion that at times of high population density
of the hosts, large, overwintered larvae left almost no food for younger, pre-
hibernating larvae of the following generation (since the foodplant is used
by successive generations in the same summer) and it is this factor which
cause often spectacular falls in the abundance of these colonial species,
tather than parasitism.

THE MYSTERIOUS SWARMS OF SEPSID FLIES AND THEIR
UNPALATABILITY TO SPIDERS

W. S. BRISTOWE

(We have recently received the sad news of Dr. Bristowe’s death at his
home in Susser on 11th January, 1979. He was an eminent arachnologist and
the author of two of the most widely read books about spiders in the
English language: The Comity of Spiders (1939-41) and The World of
Spiders (1958). In 1922 his first scientific paper appeared in the Proceedings
of this Society (Spiders Found in the Neighbourhood of Oxshott) and so
we have the distinction of having published the first and last of his numerous
contributions to arachnology. — Editor).

Introduction

The unusual occurrence of vast but strictly localised swarms of small ant-
like flies (Dipt. Sepsidae) is a mystery without satisfactory explanation. One
such swarm persisted for more than a month in my garden on one Box
(Buxus) clump and adjoining herbs. Their purpose did not seem to be
mating, egg-laying or feeding. Perhaps it is a chemical attraction. The flies
have a faint aromatic odour themselves; perhaps their congregation magni-
fies its intensity for protection (or other) purposes.

Their odour encouraged experiments as to their palatabilty to spiders. In
nature they were not seen in the webs of spiders and as they spend most of
their time walking with wings waving up and down they might be more
vulnerable to attack from hunting spiders. Was their wing-waving a
“Warning Movement’? Or did their odour serve as a deterrent?

Notes on the Flies

Sepsid flies are known to be breeders in animal dung but there were
neither dung nor drains nearby. Hundreds of thousands of small ant-like
male and female Sepsis fuleens Wied. were noticed walking actively over
the leaves of one Box (Buxus) clump on 25th August 1978. They were not

PROC. BRIT. ENT. NAT. HIST. SOC., 1979 17

visible anywhere else, nor even on ten similar Box clumps nearby, except
feeding on the heads of umbelliferous flowers. At night they remained
quiescent under the leaves or within the clump. They did not seem to be
congregated for mating, feeding on the Box or laying eggs. A month later
they were congregated chiefly amongst low herbs besides this Box clump —
grass, nettles, convolvulus, ground elder and a small azalea. Their number
had been gradually diminishing and by 26th September they had vanished
following one day of rain and a ground frost.

I could only conclude that the odour of this Box clump had attracted
them. Mr. A. C. Pont (British Museum, N.H.) kindly indentified the flies
and confirmed the occasional swarming habit of this species though he has
no other explanation to offer. He records that printing presses sometimes
attract swarms due apparently to their use of ammonia in the process.

The flies have a keen sight for movement and rapidly take to flight when
a person approaches. They fly delicately and seldom get entangled in spiders’
webs. If they do get entangled, they rapidly escape.

Their odour has been variously described. I would simply describe it as
faint, aromatic and not unpleasant.

Tests on Palatability to Spiders

I must explain that in many cases they escaped from Argiopid webs and
especially from Linyphiid webs before the spiders could catch them. When
web-builders did catch them my early tests confused me considerably. Some
spiders accepted them with or without hesitation; others rejected them after
a touch, after wrapping them in silk, after biting them, or after hesitation.
Several times I was to see spiders retire to a neighbouring leaf to wipe
away a drop which had developed from their mouths which provided com-
plete proof of the flies’ unacceptability to them. Why the variation in
behaviour?

In the field I could not be certain of the flies’ sex or whether the one
was more unpalatable than the other. After taking away some of the flies
which had been readily accepted by spiders and finding these were of both
sexes, I came to a fresh conclusion after watching the differing reactions of

Meta segmentata.

When Meta was sitting in the centre of its web, it usually pounced and
bit the fly instantly without wrapping it up. Then it usually (though not
always) went on eating it as though the body fluid was not distasteful. When
Meta took some time to emerge from a retreat and got involved in a
struggle before it could wrap it up the Mera often abandoned the fly after
(or before) a bite. Sometimes it paused after wrapping for two or three
minutes in order to go through chewing motions with its chelicerae and to
pass the tips of its palps and legs through its chelicerae. Sometimes it would
retire to a leaf bordering the web and dab away a drop of fluid which had
appeared from its mouth. The inference drawn was that the fly which was
not killed or paralyzed instantly had had time to exude or squirt some
substance which the spider found objectionable.

Experience with seven other small or immature species of web-builder
did nothing to upset this conclusion. Brief notes will show what I mean, but
it must be mentioned that the apparent deterrent seemed to be more
effective against small than against large spiders like adult Araneus diade-
matus which sometimes wrapped four or more flies in one bundle and then
ate them without hesitation.

Linyphia triangularis (Clerck)

These spiders sometimes seemed to chase the flies out of the web after

half-hearted attempts to catch them.

(a) 4 accepted.

(b) 4 accepted after killing and then pausing for two minutes during

Tegenaria gigantea Cham. and Ivie

(a) 1 immature accepted after biting followed by five-minute with-
drawal for cheliceral chewing.

(b) 5 immature killed and withdrew. One of these had killed eight
flies because it could not resist response to web vibrations. Chew-
ing motions ensued. Then it returned to spin web over the dead
flies to avoid contact with them.

(c) 2 withdrew after touch and allowed the flies to escape.

Results with Hunting Spiders

Here I was particulary anxious to see if Salticids were deterred by the

flies’ wing waving as they walked. Could this be classed a Warning Move-
ment (see W. S.fl Bristowe The Comity of Spiders, Vol. 2, p.279, 1941)?
The only ones easily available to me in September were Salticus scenicus.

PROC. BRIT. ENT. NAT. HIST. Soc., 1979 19

8. Salticus scenicus (Clerck)
4 enclosed in glass-bottomed boxes watched the flies and avoided them.
Though significant this provided no reliable proof.

9. Pardosa amentata (Clerck)
Similarly enclosed in boxes with flies, 2 made no attempt to catch the
flies and 2 others pounced, held, and then released them.

10. Xysticus acerbus Thor. (from Corfu)
In the course of weeks, this spider had eaten several small Halictus
bees. It made no attempt to hold or bite the flies.

11. Clubiona reclusa O.P.-Camb.
1 opened chelicerae but made no attempt to capture the flies.

Conclusions

1. That the sepsid flies probably congregate in huge numbers in response
to some odorferous attraction in their vicinity not in itself connected with
their mating, egg-laying or feeding.

2. That in nature these flies do not often fall victim to spiders for what
may be a variety of reasons. The most obvious is an odour which the
chemo-tactic senses of a spider can detect by touch. This odour seems to be
reinforced in the course of struggle after which a spider’s taste senses are
often affected by the emission of the odoriferous substance. These con-
clusions are based on repeated observation only.

3. Ants are not favoured as a diet by many spiders. Sepsis is ant-like in
appearance and spends much of its time walking actively. In the course of
this it waves its wings and this may represent a Warning Movement which
may deter long-sighted Hunting Spiders from leaping on them. This would
not apply when entrapped in an orb-weaver’s web where the odour deterrent
comes into play but the flies fly delicately and seem, in nature, seldom to
become so entrapped; and when they do they are able to release themselves
quite quickly.

4. The body fluid of the sepsid fly does not in itself seem to be un-
palatable to spiders and the emitted deterrent substance is not so distasteful
to spiders as the flavour of Mycetophilid flies of the genus Sciara. (The
Comity of Spiders vol. 2. p.230). In the course of a month’s close observation
I never saw the swarm attacked by insectivorous, birds or other predators.
The close congregation of the flies may well have the effect of enhancing
the deterrent powers of the odour.

THE NATIONAL COLLECTION OF
BRITISH LEPIDOPTERA (R.C.K.)
by Davip J. CARTER
(Entomological Department, British Museum (Natural History), Cromwell Road,
London, S.W.7)

Since its formation in 1947, the Rothschild-Cockayne-Kettlewell Collec-
tion, usually referred to as as the R.C.K. collection, has represented a Mecca
for students of British Lepidoptera and Lepidoptera genetics. Following the
transfer of the collection from Tring, Hertfordshire, to London in 1969
it was decided to amalgamate with it all British Lepidoptera in the British
Museum (Natural History) to form a unified National Collection. This was
in fact an extension of the original agreement relating to the formation of
the R.C.K. collection (Cockayne and Kettlewell, 1953) which permitted
selected specimens from the B.M. collections to be incorporated in the

20 PROC. BRIT. ENT. NAT. HIST. soc., 1979

R.C.K. The National Collection, which includes Microlepidoptera and
Pyralidae, is now considerably larger than the original R.C.K. collection (at
present some 5,000 drawers compared to 2,000 drawers in the R.C.K. in
1969) and provides an even more comprehensive source of reference for
further study.

The R.C.K. collection was formed by the amalgamation of the Rothschild
British collection at Tring with the combined collection of Drs. E. A.
Cockayne and H. B. D. Kettlewell. A great deal of the amalgamation work
was carried out by Cockayne but, due to failing health, he was unable to
finish this mammoth task and it was left to Mr. A. L. Goodson to complete
the curation. After the formation of the R.C.K., Cockayne continued to
support the collection by the purchase of specimens, including the famous
Castle Russell collection of Rhopalocera (Williams, 1953) and endowed the
R.C.K. with a fund to further enrich the collection after his death. Dr.
Kettlewell has continued to support the collection by donations and has
shown a lively interest in the R.C.K. over the years, culminating in the
presentation of his extensive research collection in 1978.

Before their amalgamation with the R.C.K., the collections of British
Lepidoptera in the B.M. were many and varied, including such historically
important collections as those of H. Doubleday, H. T. Stainton, J. F.
Stephens and J. H. Wood together with much material from the A. H.
Haworth collection. The Rhopalocera included the W. Rait-Smith collection
of Lycaenidae and among the Macrolepidoptera were the collections of R.
Adkin, C. N. Hawkins, A. V. Hedges and F. G. Whittle. The Micro-
lepidoptera and Pyralidae, which were not included in the R.C.K., were
richly represented by such collections as those of R. Adkin, E. R. Bankes,
L. T. Ford, T. Bainbrigge Fletcher, W. Purdey, W. Rait-Smith, W. G.
Sheldon, W. Tyerman and F. G. Whittle.

The National Collection is in the process of re-curation to bring all
material together in a coherent form. Each species will be dealt with under
three main categories. The first will be that of geographic variation and
this will be shown by series of specimens arranged on a county basis to cover
the whole of the British Isles. This category was inadequately covered in
the R.C.K. collection and the new arrangement is based on series originally
arranged at the B.M. by the late Mr. H. M. Edelsten. The second category
is that of named aberrational and varietal material which comprised the main
body of the R.C.K. This section is being greatly expanded but, wherever
practical, Cockayne’s original handwritten labels are being retained. Within
this category is included the results of breeding experiments to establish the
genetic foundations of variation, melanism, temperature effects and similar
phenomena. The final category is that of historical material and constitutes
series Of specimens from such famous collections as those of Doubleday
and Haworth.

Detailed accounts of accessions to the R.C.K. collection weere published
by Riley (1948 and 1950), Cockayne (1953 and 1954) and Goodson (1960
and 1968) but no recent list has been produced. It is not practical to give a
detailed account of the extensive accessions since 1968 but the following is
a résumé of the more important acquisitions.

1968

The Bessemer collection of British Macrolepidoptera was purchased by
the Cockayne Trust. This large and valuable acquisition of some 17,000
specimens, including many rarities and figured specimens, is the most impor-
tant purchase to have been made by the Trust.

1969

PROC. BRIT. ENT. NAT. HIST. soc., 1979 21

A bred series of Eugraphe subrosea Stephens from Wales was presented
by Mr. J. M. Chalmers-Hunt, the first representatives of this Welsh popula-
tion for the collection.

1970

The R. M. Craske collection of British Rhopalocera was purchased by
the Cockayne Trust. This fine collection of some 5,600 specimens contained
many rare aberrations and forms and has been subsequently augmented by
annual donations of new material from Mr. Craske.

The late Mr. A. J. Wightman bequeathed 1,348 specimens of Noctuidae.
These had previously been selected by Mr. Goodson from Wightman’s
extensive collection which is now in the care of Mr. G. Haggett.

1971

Mr. W. G. Tremewan presented about 2,800 Macroheterocera from Corn-
wall to the National Collection. This area of the British Isles was previously
very poorly represented.

The late Sir Robert Saundby bequeathed his comprehensive collection of
some 15,000 specimens of Macrolepidoptera including many from areas
previously unrepresented and a number of rare aberrations.

The L. T. Ford collection of varieties of Acleris cristana Denis & Schiff.
and Acleris literana L. was purchased by the Cockayne Trust. This impor-
tant collection, containing many types, was one of the finest in private

1972

The late Col. A. E. Collier bequeathed his fine collection of British
Rhopalocera containing approximately 3,000 specimens with many rare
forms and bred series with notes on genetics.

1973

The late Mr. G. A. Cole bequeathed 1,042 specimens of Macroheterocera
selected from his extensive collection with many specimens from Northern
Ireland and a number of rarities including one specimen of Luperina zolli-
koferi Freyer.

Dr. C. G. M. deWorms presented the first specimens of Chloroclystis
chloerata Mabille to have been taken in the British Isles.

Mr. L. A. Durden presented the second specimen of Ochropleura
fennica Tauscher to have been collected in the British Isles.

1974

The N. A. Watkins collection of British Rhopalocera was presented to
the National Collection. This collection of some 10,000 specimens was one
of the finest in private hands and contained many rarities and fine bred
series.

The collection of the late Mr. D. A. Ashwell was presented by Mrs.
P. H. Ashwell. It consisted of about 3,000 British Macrolepidoptera and
included series of forms of Abraxas grossulariata (L.), which were the
results of extensive breeding experiments.

The first British specimen of Semiothisa signaria Hiibner was presented
by Mr. R. Tomlinson.

1975

The R. W. Watson collection was presented to the National Collection.
This magnificent collection of some 50,000 specimens immaculately curated
in 52 ten drawer Hill units comprises the largest and most valuable donation
since the formation of the R.C.K. collection. It is particularly rich in
Rhopalocera and contains many figured specimens and types of aberra-
tions. Among the Macroheterocera are remarkable bred series of Tyria

92 PROC. BRIT. ENT. NAT. HIST. soc., 1979

jacobaeae f. coneyi Watson and related forms. The collection bears a
Museum registration but remains in the hands of Mr. Watson until such
time that he sees fit to relinquish its care.

Mr. B. Goater presented the type series of Luperina nickerlii ssp. leechi
Goater.

1976

The J. M. K. Saunders collection of Macrolepidoptera was presented by
Pinner Junior College.This contained some 5,000 specimens with many
rare aberrations and material from areas otherwise poorly represented in
the National Collection.

1977

The late Mr. H. C. Huggins bequeathed his collection of British Lepidop-
tera to the Museum. This contained about 19,000 specimens and included
Rhopalocera, Macroheterocera, Pyralidae and Tortricidae. Many rare species
and forms were represented including fine series from Southern Ireland.
His collections of Pyralidae and Tortricidae were among the finest in
private hands.

Mr. S. N. A. Jacobs presented his large collection of British Microlepidop-
tera. This important collection of approximately 14,000 specimens contained
many of historic importance, including the Microlepidoptera collected by
W. Fassnidge.

Mr. A. T. Hedger presented the first specimen of Arethusana arethusa
Denis and Schiff. to be taken in Britain.

Mr. J. B. Fisher presented a series of Gortyna borelii, previously un-
represented in the National Collection.

Dr. G. A. N. Horton presented the first specimen of Eriopygodes
imbecilla F. to be taken in the British Isles.
1978

Dr. H. B. D. Kettlewell presented his important research collection of
British Macroheterocera formed during his investigations of Lepidoptera
genetics and melanism. This collection of some 3,000 specimens contained
bred series of many species.

The W. Reid collection of British Macroheterocera was purchased by the
Cockayne Trust. This contained about 10,000 specimens, mainly from the
Sheffield area, and was very rich in melanic examples.

Many other donations have been received during the last ten years but
it is not possible to list them all. Among those who have regularly presented
specimens are Messrs. L. Christie, R. Ford, B. Goater, R. I. Lorimer and
A. S. Wheeler. Mr. Lorimer has presented a fine collection of Orkney
Lepidoptera over this period, a most important acquisition from an area
otherwise poorly represented.

In parallel with the development of the British Lepidoptera collection of
imagines, the collections of immature stages have also been expanded in
recent years. These collections were founded on 30 drawers of blown larvae
in the R.C.K. collection and a small spirit collection made by the late Mr.
H. M. Edelsten. The present collection, consisting of 60 drawers of blown
larvae and about 700 jars of spirit collection, is supplemented by a collection
of about 3,000 colour transparencies of immature stages to show their
natural coloration. A great deal of this progress has been made possible by
the efforts of a number of field entomologists, particularly Messrs. G.
Haggett and R. I. Lorimer, who have provided a steady stream of live
material during the last few years.

PROC. BRIT. ENT. NAT. HIST. soc., 1979 23

It is apparent from this account that support for the National Collection
has not diminished since its inception but indeed the flow of material over
the last few years has considerably increased. Unfortunately it is not
possible to accept all collections indiscriminately as storage space is limited,
even though individual collections are not retained intact but are incor-
porated into the existing system. Many generous benefactors have donated
rare or interesting specimens from their collections whilst others have made
provisions enabling a Museum representative to select interesting specimens
from their collections after their death. An area in which the collection is
still in particular need of support is that of immature stages. Whilst this
part of the collection is being actively expanded, there are still many species,
particularly of Microlepidoptera and Pyralidae, which remain unrepresented.

The National Collection is housed in the Entomology Department of the
British Museum (Natural History) and access to specialists and serious
students is by appointment only during working hours from Monday to
Friday. The Watson Collection is the venue of an annual Spring field meeting
of this Society and is also open to study at other times by personal appoint-
ment with Mr. R. W. Watson, “Porcorum’’, Sandy Down, Boldre, Lyming-
ton, Hampshire.

A REVIEW OF VARIATION IN PIERIS BRASSICAE (L.)
(LEP., PIERIDAE)

(with Plates III-VI and text figs. 1, 2)
by BRIAN O. C. GARDINER
(Unit of Invertebrate Chemistry and Physiology, Department of Zoology, Univer-
sity of Cambridge, Downing Street, Cambridge)
Introduction

Altogether some seventy races, forms, varieties or aberrations of Pieris
brassicae L. have been described, of which fifty are said to have been
found in the British Isles. Some races are distinctive and geographically
isolated; e.g. race cheiranthi Hiibn. in the Canary Islands. Some forms have
been shown to be due to simple recessive alleles; e.g. albinensis Gardiner
(Gardiner, 1962) or to environmental factors; e.g. minor Ksienschopolsky
(Gardiner 1963). The first generation or spring form throughout its range is
of a lighter colour than the summer or later generation broods and is
generally considered so by being designated chariclea Stephens. Apart from
a few forms which in my opinion are certainly due to a recessive allele, such
as flava Kane and two or three which may well prove to be environmental
(for example vasquezi Oberthur), the majority of the various forms which
have been named vary solely in the size and positioning of the black mark-
ings on the wings, or, in a few cases, the degree of darkening of the
underside of the hindwing. The last general description of these varieties
is that of Graham-Smith and Graham-Smith (1929-30) who dealt with the
subject as a whole, and of Lempke (1953) who reviewed those found in the
Netherlands. What little is known about the genetics of brassicae variation
is briefly summarised by Robinson (1971). The present paper is the result
of breeding some 200 generations of brassicae over a period of 25 years,
during which time both a number of varieties have been observed and most
of the named transitional and local seasonal forms have appeared. It has
also been possible to do a number of breeding and hybridization experi-
ments. These show that the factors governing the underside colour of the
hindwing and the factors governing the extent of the black markings are
controlled by multiple alleles. They also show that there is a graded series
and that many of the named varieties gradually merge into each other
which makes it difficult, indeed at times impossible, to say specifically that
a particular specimen should be referred to var. “‘A’’ or to var. “B’’. In a
sense many of the varieties named on account of the variation in the black
markings should be considered transitional forms towards race cheiranthi.
The various combinations possible between the named varietal forms are
seemingly endless, as also is the degree of any particular variation. For
instance, the variety biligata Cabeau, as described, consists of a few black
scales joining the apical blotch to the upper discal spot under nervures 2 and
4. In fact it is found that all stages exist from the few scales along the
nervures to the complete fusion and enlargement of the apical blotch and
the upper discal spot into one continuous and inseparable whole—which
may then go on to fuse with the lower discal spot and the submedian streak.

The schematic representation of some of the varieties and combinations
that are possible in the extent of the black markings are shown for the
female uperside in Fig. 1.

I also feel that the validity of some of the varietal names is untenable.
For instance different names have been put forward for what is in fact the
same variety, but in separate sexes. For example, the name infrafasciata
Graham-Smith and Graham-Smith was introduced specifically for the

joining of the discal spots on the underside of the wings. Lempke (1953)
states that he has never seen a case of (in the female) the variety fasciata
occurring on one surface only, as stated by the Graham-Smiths’ and neither
have I in the tens of thousands of examples I have seen, including original
Graham-Smith material. Since therefore fasciata covers all cases the names
suprafasciata and infrafasciata must be considered superfluous. In my
opinion the type of infrafasciata can in any case be referred to as true
fasciata. The original type is shown in Figs. 10 (upperside) and 13 (under-
side).

Many of the varieties have been found randomly over the years in the
continuously brooded stock of brassicae designated the ‘‘Cambridge”’ stock.
This stock is still being maintained, is now over 25 years in culture, is used
by many laboratories and the culture methods as described by David and
Gardiner 1952, 1966 are still in use. The other stocks examined were the
“virus free’? which originated in Oxford; the cheiranthi, and the Hereford,
which have been described in previous papers by David and Gardiner 1965,
1966 and Gardiner 1973.

Additionally the original material on which Graham-Smith and Graham-
Smith based their 1929-30 paper has been re-examined together with the

26 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

series of Pieris species in Cambridge University, Department of Zoology,
various private collections, and much European material supplied to me by
various colleagues and the collection in the British Museum (Natural
History). All rearing was done under non-diapause conditions so all varieties
bred are of course of the summer form.

In the continuously brooded Cambridge stock of brassicae approximately
eight generations a year are obtained, and have been, for the past twenty-
six years. The stock is normally reared on such varieties of brassica Cabbage
species as may be available and sometimes several generations are run
through on an artificial diet. The fact that a number of varieties occasionally
turn up in this stock has already been noted (Gardiner 1973). From time to
time over the years unusual looking specimens have been noted in the
culture, killed and retained. It is considered almost certain that others have
been overlooked.

Apart from the distinctive recessive alleles, and the gynandromorphs,
most such varieties have shown a reduction in the extent of their black
markings, or have had unusual wing shapes. The culture has been main-
tained under a variety of conditions of temperature and humidity from
time to time and it has been noticed that the general appearance and size
of the adults tends to fluctuate. This is certainly due to the differing
environmental conditions under which they have been reared and has had
the interesting result that many of the named races generations, forms and
sub-species of brassicae have been bred from the one culture with the
exception of those isolated populations such as nepalensis which show a
consistent major variation in the extent of black markings.

Actual experiments with breeding where multifactorial effects have been
involved have basically been confined to the cross of Cambridge brassicae
with Canary Islands cheiranthi. These crosses and the evidence from the
Hereford stock show that the amount of black markings is controlled by
multiple alleles and so also is the colouration of the underside of the hind-
wing. (Gardiner in preparation).

In a number of publications the wingspan of insects is often quoted. The
two extremes of size in brassicae, minor and major arte so quoted and
named on account of their small and large size respectively.

The wingspan of Lepidoptera (and other insects) can be measured and
expressed in at least two ways. Unfortunately most of the authors who quote

Cc

B

tion see text.

PROC. BRIT. ENT. NAT. HIST. soc., 1979 27

wingspan do not quote the parameters of which method they used. This is
unfortunate as it leads to ambiguity and consequent misinterpretation by
subsequent authors, even when at times the parameters of measurements
may be clear (although not quoted) from an illustration.

The usual method apparently quoted is that shown in Fig. 2 when the
specimen is set with the hind margin at right angles to the line of the
body. However this can be variable on two accounts, firstly if the specimen
is poorly set and secondly if the outer wingmargin be convex which permits
the measurement to be taken either at the apex or at the widest part. It
can be seen from Fig. 2 that the only constant method is to measure the
distance from the centre of the thorax to the wing apex, call this distance
H and multiply by 2. This method is independent of the angle of set of the
wings and also can be carried out much more easily on live specimens,
although perhaps requiring more care on dead ones.

From Fig. 2 it can be seen that H is the hypotenuse of a right-angled
triangle and is also the radius of a circle at a centre A. In set specimens
the angle 6 of this triangle can be measured. Since H is a radius, it is
independent of the angle — that is to say the ‘set’ of the wings — but the
distance AB, so often used in wingspan measurements, is not. For
specimens which have been measured wing-tip to wing-tip, distance Y,
then H = .5Y/Cos @ or, conversely, as it may sometimes be easier for
comparative purposes to convert the other way, Y = 2 Cos 6H. When a
published figure is given by an anthor it is usually possible to measure it and
this may tell which parameter of measurement has been used. When there
is no published figure, or other evidence, the usual (but unfortunately not
invariable) method of quotation has been to use Y, the wing-tip to wing-tip
measurement of a set specimen but not necessarily with the hind margin
set at right angles to the body.

There exists considerable confusion in the literature over various seasonal
forms and races. Verity (1916) stated for instance “The migratory habits of
P. brassicae have probably contributed in maintaining the lack of variation
observed in the whole of Europe. Seasonal dimorphism is however, well
marked in the whole of its range’. Never-the-less he later (Verity, 1947)
illustrated and listed many seasonal forms. These forms will be discussed
below under their respective names. The fact that so many of them have
appeared in the Cambridge stock and that it is rarely possible to decide
between them, leads me to the opinion that all colour and marking varia-
tions in brassicae are due to environmental factors modifying the facies with
the result that, given the appropriate weather conditions a form believed
peculiar to one region can appear in another. It does seem quite obvious
that overwintered pupae do produce specimens with darker undersides and
paler black markings (chariclea Stephens). But all other slight colour and
size variations — and they are but slight on the whole — run gradually into
each other and vary enormously from year to year and indeed from
month to month in the continuously brooded Cambridge stock.

In the account which follows I have not been able to see all the named
forms, although I have had examples of many, in order to compare with
my own bred specimens. In some cases it has not been possible either
to get an expert translation of the original description nor, in two or three
cases even track down the original reference. Never-the-less it is felt that
even these should be included in the list of varieties to follow for the sake
of completeness. In the majority of cases, however, I have personally looked

28 PROC. BRIT. ENT. NAT. HIST. soc., 1979

at the original references, some of which I discovered, had been misquoted
previously. Those not tracked down are from references quoted, but without
title, by Graham-Smith & Graham-Smith (1929-30).

Varieties

In so far as they are known to me, all the various varieties, forms,
abberrations, and races of brassicae are described below in alphabetical
order.
albinensis Gardiner (1962)

This variety is characterised by the absence of any black pigment in the
wingscales or body hairs. The imago has difficulty in emerging from the
chrysalis. It is due to a recessive allele and its origin and breeding from the
‘Cambridge’ brassicae stock has been described by Gardiner (1962).
aestiva Zeller (1847).

This name was applied to the second generation specimens and as inter-
preted by Verity (1908) really applies only to South European brassicae.
Whether or not successive broods should have differing names, is a matter
of opinion. To my mind many of the differing forms of brassicae. blend
into each other and it is usually quite possible to find the ‘wrong’ form
amongst the right ones (as specified) at any given time. Over the many
years of breeding the same strain so many of the named forms have turned
up, at times in quantity, it is, in my opinion, certain that they are due to
climatic factors which of course vary not only from region to region but
also from season to season. There is also confirmed evidence that differing
foodplants (coupled perhaps with semi-starvation) and temperature of
rearing can affect the facies of the adult.
aestivalis Turati (1924)

This is a variety of race cyniphia Turati, which occurs in Cyrenaica and
in which the underside of the male is described as whitish-green instead of
greenish-yellow. Specimens of cyniphia can be produced from the Cambridge
stock (see below under cyniphia) and the underside colour of these may or
may not also be of var. aestivalis. It is probably environmental, caused by
hot dry conditions but since underside colouration changes can also be
caused by multifactorial factors, genetic isolation of the North African
population cannot altogether be dismissed.
aligata Cabeau (1924)

Is a synonym of fasciata Kiefer (1918)
alpina Rocci (1919)

Erected to describe a population found above 1,200 m. in the Pied-
montese Alps, where it is univoltine and the single generation possesses
characters of both the spring (chariclea) and summer (aestiva) forms.
anthrax G-S and G-S (1930) (syn. nov.) (Fig. 14)

Described from a male in which the undersides of the hindwings are so
densely suffused with black scales that they have a very dark appearance.
I have bred nomotypical examples as illustrated by the Graham-Smiths’
and such dark undersides appear to be common in examples I have from
Spain, Malta, Chile and from weakly diapausing pupae. In my opinion,
this is the opposite extreme to pallida and one end of a continuous variation
controlled by multiple alleles.

After careful consideration and examination of examples including the
Graham-Smiths’ original material I am also of the opinion that anthrax
as described cannot be separated from nigroviridescens Rocci (1919) which
takes precedence and it must therefore fall as a synonym. See further
discussion under nigroviridescens.

PROC. BRIT. ENT. NAT. HIST. soc., 1979 29

The Graham-Smiths suggested that a specimen, exhibited by Leeds
(1909) “with undersides of the hindwings a very distinct blue” was perhaps
an example of this aberration. In this they were mistaken for I have seen
this specimen which is undoubtedly coerulea. Furthermore later in their
paper the Graham-Smiths state that this same specimen is a very marked
example of their ab. pallida!
autumnalis Rocci (1919)

According to Rocci this is the form of specimens found in October
through November around Genoa and the Ligurian litoral. It is described
as smaller than chariclea but larger than /epidii or meridionalis, and has
slightly differing colour than typical. Here again we have what I consider
an environmental form, not really distinguishable from many others.
aurea Moseley (1896)

Is a synonym of flava Kane (1893).
aversomaculata Lempke (1953)

A variety known only in the male where there is a spot formed by
black scales on the underside of the forewing near the apex. An occasional
specimen has been found in both the ‘Cambridge’ brassicae and in the
cheiranthi hybrids but otherwise this variety has not been investigated.
azorensis Rebel (1917)

There is obviously some confusion over this one. Specimens from the
Azores have been described both as a sub-species and as “‘indistinguishable
from typical brassicae”’.

I would suggest that here is a clear case of facies in any particular year
being directly modified by climatic factors. In support of this is the fact
that a number of authors (see Verity, 1907 and Graham-Smith and Graham-
Smith, 1930) had previously considered it as the European spring form
chariclea.
basi-nigrescens Graham-Smith and Graham-Smith (1930) (syn. nov.)

Although figured in their work (as a copy of a previous line engraving)
Graham-Smith and Graham-Smith did not describe, but designated the
specimen captured at Leicester in 1842 (Plant, 1844) as the type and I
have not been able to trace its present whereabouts. The veinal shading as
is shown in the illustration in the Graham-Smith paper does not exist in
the original illustration to Plant’s note, which is dated 1844, although the
date 1843 is given by the Graham-Smiths’. Further discussion on this and
other subdivisions of nigrescens, will be given under that variety, of which
it is in fact a synonym.
biligata Cabeau (1925)

Is a synonym of striata Rocci (1919).
bi-nigronotata Graham-Smith and Graham-Smith (1929)

Occurs only in the male. In addition to the male spot of nigronotata (see
below) there is an additional spot between nervures 1 and 2. Such specimens
exist in the Graham-Smiths’ material but I have never come across this
variety in any specimens bred by mae.
carnea Graham-Smith and Graham-Smith (1930)

Described most unsatisfactorily by the Graham-Smiths’ as follows: —
“Newman (1916) exhibited two pairs (a part of a series) of Pieris brassicae
bred from wild Aberdeenshire larvae, the males especially showing a
decided pink colouration all over the wings”. They make no further
comment nor do they illustrate the variety. Since no type can now be desig-
nated and for the reasons given below, I propose this variety be suppressed.

30 PROC. BRIT. ENT. NAT. HIST. soc., 1979

The pink colouration can be produced in two ways, both of which I
have tried. The first is by staining with meconium from another specimen
just as eclosion occurs and before wing expansion. The second, which only
sometimes produce the pink suffusion, is to kill the specimenn while the
wings are still soft and the same time rupture one or more of the wing
nervures thereby causing leakage of fluid onto the wings. Apart from these
purpose-produced specimens, I have examples which appeared postmortem
after possing through a potassium cyanide killing-bottle. Usually the effect
is partial and it is more common for the hindwing to be affected.

It is perhaps interesting to note the Graham-Smiths’ quotation comes
from the reports of exhibits shown at a meeting of the Entomological
Society of London on March 15th 1916. Newman, however, had already
exhibited them a few days earlier at a meeting of the South London
Entomological and Natural History Society on March 9th, 1916 and their
exhibition report gives more information. Both reports are to be found on
the same page, 116, of the Entomologist for 1916. The former is already
quoted above; the latter is as follows: “Mr. Newman exhibited, on behalf
of A. Horne, Esq., bred specimens of Pieris brassicae from Aberdeen, with
a very distinct pink tint over all the wings, and a Noctuid . . .”’. Between
the two exhibition dates the specimens no doubt changed ownership.
Interestingly enough these were bred specimens and I can trace no case
of a wild caught pink specimen.
catoleuca Rober (1896) (Fig. 22

This name was originally applied to second generation specimens from
the Syrian region but these specimens cannot be distinguished from other
brassicae throughout Southern Europe and Graves (1925) considers it a
synonym of verna. As usual it can be found in both the Cambridge and
virus-free stocks even in wild caught specimens from the local population.
chariclea Stephens (1828) “

This is the spring form in which the intensity of all the black markings,
but especially that of the apical blotch, is considerably reduced. In the
majority of such specimens examined by me, from all the sources, the
hindwing underside is also of a darker and greener colour than in summer
brood species. The form can be produced at will by allowing the chrysalids
to enter diapause and then keeping them for several months at or near
freezing point. If pupae, in diapause, are kept warm, instead of being
chilled, there is often a steady trickle of emergences over several months.
This may well be associated with the diapause having been initiated by a
minimal response. In these specimens the wingtips are usually normal but
the dark underside is always present. Investigation of chariclea has not
been undertaken in view of the fact that the brassicae are kept in con-
tinuous culture without diapause and are not therefore normally of this
variety. It is clearly an environmental form and occurs whenever there is
a diapausing stage.
cheiranthi Hubner (1806) (Figs. 17, 34)

This is the race from the Canary Islands. It is large; in my experience
with fresh specimens more yellow; with all the black markings very exten-
sive and the males all nigronotata. Obviously it is an isolated race and
non-migratory. The larvae feed only on Nasturtium (Tropaeoleum)
(Fernandez, 1955) and when fed on cabbage I have found there is a high
mortality. It pairs readily with Cambridge (and other) brassicae to produce
an F.1 intermediate between the two parents. The F.2 shows a complete

PROC. BRIT. ENT. NAT. HIST. soc.. 1979 31

gradation of forms between the original Parent generation thus demonstrat-
ing the multiple allele control of the black markings, size and underside
colouration. How did it arise? There is a strong (but quite unprovable on
present evidence) probability that it was introduced as nomotypical
brassicae some time in the sixteenth century after the introduction of
Nasturtium from the newly discovered Americas. Subject then to a new
environment the genetic drift eventually, even quickly, produced the
present facies. Already we have evidence that such a thing is happening
in Chile (Gardiner, 1974). The evidence from the Hereford stock of bras-
sicae, in which this English stock produced in effect specimens indistin-
guishable from F.1 cheiranthi/brassicae hybrids shows that the halfway
step already exists. Gardiner (1973) has already shown that selection of
the blacker specimens leads back to the cheiranthi end of the facies
variation.

This is also the only race of brassicae in which the larva and pupa show
a marked difference from the nymotypical form.
colliurensis Gelin (1914)

In this variety the black costal blotch on the hindwing is absent. There
is considerable variation in the intensity of colour and, but to a lesser
extent, the size, of this black spot. In all examples in my possession or seen
by me the size and intensity is directly related to size and intensity of the
other black markings on the insect; as they are reduced, so is this spot; in
specimens which have been reared at high temperature; in var. minor; in
specimens reared on white ‘‘Dutch pride” cabbage, it tends to be absent.
It would appear therefore that colliurensis is part of the multifactorial
complex governing the amount of black present and, like the other black
areas, is capable of being modified by environmental conditions. fischeri
John (1922) is a synonym.
coerulea Gardiner (1963)

In this variety the wings are of a pale blue colour and difficulty is
experienced in eclosion. It has previously been shown to be due to a
recessive allele (Gardiner, 1963). A particularly fine example was figured,
but not named, by Frohawk (1924), Plate 3 in his famous book of British
Butterflies.
cyniphia Turati (1924)

Described to distinguish a race occuring in Eastern Lobya (Cyrenaica),
they are allegedly small with reduced black markings. The upper side of
the hindwing is said to be greenish-white and the underside greenish-yellow.
Here again we have a race of which specimens appear in the Cambridge
brassicae and in the virus-free stock. The matter is confused, however, as
my own specimens from Derna do not agree with Turati’s description and
appear to be perfectly ordinary nymotypical, brassicae in both their size
and facies. In my opinion therefore cyniphia can be considered an environ-
mental form and by no means confined to Cyrenaica.
cyniphiodes Rocci (1930) (syn. nov.)

Described as having the female resembling cyniphia with small spots and
the subtriangular mark extremely short, its lower extremity hardly reaching
the level of the upper dorsal spot. It is dusted with white in its apical
portion and crossed or interrupted by the nervures. Here again we have
another example of pale specimens and these occur in the Cambridge
stock either when fed on white (Dutch pride) cabbage or are reared at
high temperatures. In any case I really do not consider one can tell it
apart from cyniphia and the name should be sunk as a synonym.

39 PROC. BRIT. ENT. NAT. HIST. soc., 1979

The cause of the blue colour is apparently due to xanthopteron and
erythropteron which are present in normal brassicae (Harmsen, 1964).
elongata Gelin (1914) (Fig. 28)

This was described as with marked narrowing of all four wings. The
type was a small specimen (50 mm.) but not so small as to be referable to
ab. minor. Such distorted specimens occur from time to time in all bred
stocks of brassicae and are due to mechanical deformation in the pupal
stage. Gelin did in fact suggest this in his original description and I concur
in the fact that it is a teratological specimen.
emigrisea Rocci (1919) (syn. nov.)

I consider this to be synonomous with vazquezi.

fasciata Kiefer (1918) (Figs. 10, 13, 15, 16)

In this variety the discal spots are joined to each other and to the apical
blotch by a sprinkling of black scales. The Cambridge stock has produced
virtually no such specimens but the cross brassicae x cheiranthi are
invariably all strongly fasciata, as was also a brood of brassicae originating
from Hereford. When taken to the F.2 an infinite series is produced and it
is not really possible to define the point at which ‘fasciata’ fades out, or,
alternately merges into ‘cheiranthi’ or some of the other named varities.
In all the tens of thousands of specimens seen, when fasciata occurs it is
present equally on both upper and under wing surfaces and on the under
surface of the sibling males when present in the female. The use of the
names infra-fasciata Graham-Smith and Graham-Smith and supra-fasciata
Graham-Smith and Graham-Smith are therefore superfluous and these
names must sink as synonyms.

The situation governing this variety is clearly very complex. It occurs
regularly in the isolated races cheiranthi, nepalensis Doubl., and wollastoni
Butl. When produced by the cross brassicae x cheiranthi, the F.2 produces
an infinite graded series but when the ends and middle of this series are
crossed inter se they tnd to reproduce themselves and, as has been shown
(Gardiner, 1973) for cheiranthi we eventually return to the original parental
forms. The stock from Hereford was clearly unusual in that fasciata just
appeared shortly after it was obtained and these bred true.

Could this be a chance combination of alleles which, given the right
conditions of isolation would be capable of forming a new subspecies?

In the late 1920’s the Graham-Smiths reported a high percentage of
fasciata from Aberdeenshire stock, often combined with other varieted
forms. All of these were very ‘weak’ in the sense that the extra block
scaling consisted of a small proportion of black scales scattered amongst
the white. In the specimen illustrated by for example Frohawk (1934) as
fasciata these black scales are very extensive and the joining of the normal
black areas becomes continuous. Thisvariety does not occur in the Cam-
bridge stock and this fact, together with its unexpected and very strong
appearance in the Hereford stock, its occasional and variable appearance
in the other stocks, and the evidence from the cheiranthi leads to the
opinion that, given the right combination of genes, fasciata will appear,
and once there selective breeding can maintain its strength.

fischeri John (1922)

Is a synonym of colliurensis Gelin (1914) but in any case the type of
John’s fischeri as illustrated is P. rapae L.

PROC. BRIT. ENT. NAT. HIST. soc., 1979 33

flava Kroulikovski (1902)

Is a synonym of flava Kane (1893).
flava Fischer (1925)

Is a synonym of flava Kane (1893).
flavus Frohawk (1938)

Is a synonym of flava Kane (1893).
fldvopicta Rocci (1919)

This name is applied to specimens with very pale underside colouring to
the hindwings. Rocci’s original description (translated) is “from the base
of the hindwing underside yellowish slightly dusted with black”. It is
in fact one end of the continuous variability in underside appearance. It
should not be confused with jauni (seq) as has been suggested by Goodson
(in lit), but which is of entirely different aspect and in which the pupal
colour is also affected.
flava Kane (1893)

The wings of a lemon-yellow colour. This appears to be the rarest of all
the varieties, although quite common in the related P. napi L. Two
specimens have turned up in the Cambridge stock and unfortunately it
was not possible to breed from them. In my opinion, it is due to a recessive
allele, as in coerulea and may well also be coupled with difficulty in eclosion.

The names aurea Mosley (1896); Jutea Rober (1907); flavus Frohawk
(1938) and brassicae-flava Fischer (1925) have all been applied to a yellow
form of brassicae. The description of each author varies and the only real
method of comparison would be to get all their respective specimens side
by side. Kane’s flava is in fact the specimen recorded (but not named) by
Mosely who then, three years later named the same specimen aurea.
Perhaps the earliest specimen was that recorded (but again not named) by
Schoyen in 1885. Kane described both these specimens as sulphur-yellow
whereas Mosley (who was of course describing the same specimen) likened
the ground colour to golden-yellow. R6ber’s aurea was described as bright
yellow. Frohawk’s flavus is sulphur yellow and Fischer’s figure of brassicae-
flava is canary yellow. In these circumstances I consider, as have others
before me, that the name flava Kane applies to all yellow forms of brassicae
and all other names are synonyms. The name flava Krulikovsky (1902) falls
as already occupied.
fuscosignata Lempke (1953) (Figs. 8, 9)

The dark markings on the upperside of the wings brown-black. I am
a bit suspicious of this variety and strongly suspect it is due to chance
environmental conditions. I have two such male specimen and a few others
in which the effect is bilateral and which are known to have been produced
postmortem so it is certain that this form can be produced as the result of
some accidental contamination or chemical change under certain (but un-
identified) conditions. One of the former was bred from onto the F.4
without obtaining anything but normal brassicae. It is my opinion that
the browning of the black colour is either due to its being overridden with
pink (meconium, as for example carnea) or a change due to chance
contact with some chemical or perhaps fungal spores or other. Exposure
to direct sunlight over a period of several weeks does not produce it.
glaseri Muller (1925) (Figs. 27, 29)

Absence of terminal black streak. This is another aspect of the multiple
allelics control of size and intensity of the black markings. Appears
occasionally in Cambridge stock.

griseopicta Rocci (1919) (syn. nov.)

In this variety the female is described as having the black markings pale
grey instead of the normal black and it occurs solely in the first (spring)
generation. I consider this to be merely a pale form of chariclea Stephens
(1828) as his description of his var. B: ‘‘with the apical spot of the anterior
wings unclouded, very pale, cinerous . . .”. exactly fits the above description.
In any case the name vasguezi Oberthur (1913) would have priority when
this form occurs in the summer generation, as it sometimes does.

gynandra Rocci (1930)

Created as a name for a halved gynandromorph caught at Milan, the
name is unnecessary and the use of such a term for gynandromorphic
Lepidoptera has not in fact been generally followed.

gynandromorphs

Examples of both halved and partial gynandromorphs appear from time
to time in the Cambridge stock. A number of sexual mosaics appeared in
the Hereford Stock and two or three partial examples in the cheiranthi
hybrids, while two examples were found in the early days of the virus-free
stock. I do not consider that any special naming of these is required and a
full account has already been published (Gardiner, 1973). It seems quite
clear that, although rare, gynandromorphism, complete or partial, is of
regular occurrence in brassicae.

henriettae Pionneau (1924)
Is a synonym of vasquezi Oberthur (1913).

homeosis

This name is applied to specimens where the pattern or part thereof of
one wing is repeated on another wing where it does not normally occur.
Occasional specimens are known, three of which occurred at one time in
the brassicae/cheiranthi hybrid stock. One of these was illustrated by
Gardiner (1963) and an earlier example by the Graham-Smiths (1930). No
other examples are known to me and I suspect they are due to miscegena-
tion when pairing occurrs between isolated stocks —something which
chance migration could ensure as a regular happening.
infratrinotata Caruel (1954) (syn. nov.)

As described this variety consists of a male infrafasciata (see below)
with an additional spot, composed of a mass of grey scales, situated in line
with the other spots not far from the costa. But such a spot is of course
aversomaculata! Whether a combination of two or more varieties should
receive yet a third name is a matter for opinion. I do not think so. In any
case this type of specimen occurs in a few of the cheiranthi hybrids.
infra-fasciata Graham-Smith and Graham-Smith (1929) (syn. nov.) (Figs.
10, 13)

The Graham-Smiths’ applied this name to fasciata occurring only on the
underside of the wing. I agree with Lempke (1953) that there is no known
example. I have examined the specimen labelled as type in the Graham-
Smiths’ material. The underside is indeed faintly fasciata but so also is
the upperside, sufficiently so in relation to the total relative weak scaling,
in my opinion, to invalidate the use of a separate name which therefore
sinks as synonym of fasciata.
italorum Stauder (1921)

Another local form named from some specimens taken in the Appenines.
Again I am of opinion this is environmental and does not occur every
year in its type locality.

PROC. BRIT. ENT. NAT. HIST. SOC., 1979 35

jauni Gardiner (1963)

Another variety due to a recessive allele (Gardiner 1963), in which both
the chrysalis and the hindwing of the adult are affected, being a golden
colour. This variety is interesting in that it is the only known instance in
brassicae of a gene effecting two stages of the insect. In all other instances
this is not so, indeed it is known that the chrysalis may be of several colours
without any affect on the adult (Gardiner, 1974). This variety appeared in
the virus-free stock and has never been seen elsewhere. It was unfortunately
lost before it could be more fully investigated and in spite of many years
continued breeding of the stock has not reappeared.
lacticolor Lempke (1953)

The ground colour of all wings not white but creamy. It is not easy to
decide whether this may be a partial stage towards var. flava or even a
form like jauni but with the golden colour transferred to the upperside.
I have some cheiranthi hybrids of this form — indeed the hindwing is even
more extreme, being of an orange colour along the fore-edge. Sometimes
whole batches of the Cambridge stock specimens are creamy rather than
white.

There is a definite tendency for weakly diapausing specimens, emerged
by constant warmth without prior chilling to be creamy rather than white.
The whiter specimens in fact seem to be those which are produced under
warmer conditions, although cheiranthi is an exception. This rather argues
that it may be caused by some, at present unknown, combination of environ-
mental factors. It is at any rate impossible to tell in a graded series exactly
at which point the term Jacticolor should be applied and it does seem to be
near the middle point of a range of colour from an almost pure white to
the bright yellow of flava even though I am of the opinion this is produced
by a dfferent cause.
lepidii Rober (1907)

This name was applied by R6ber to the summer form on the grounds
that it differed from the spring form. Here we again have a form whose
facies is caused by the environmental conditions and which grades into all
the other seasonal and local named forms. It does of course occur in all
stocks bred by me.
longomaculata Lempke (1953)

The discal spots distinctly lengthened. They do indeed vary in size and at
times there is a distinct cut-off along the edge of the nervures instead of
the spots spreading over. This gives them an elongated look. Additionally
the spots elongate very markedly in races cheiranthi, wollastoni, and
nepalensis, and in some fasciata forms, but the effect is obscured as they
thicken also. This variety would seem therefore to be part of the multi-
factorial complex and to be brought about by certain combinations of the
alleles involved. Spots of normal size, but otherwise elongated, I have not
come across.
lutea Rober (1907)

Is a synonym of flava Kane (1893).
major Verity (1947)

A varietal name applied by Verity to larger than normal specimens. But
what is normal size? It depends on various factors; cheiranthi for instance
are larger than normal and so are any specimens I have bred which are
both well fed, not too crowded and not too hot. Size is relative; there is a
continuous graded series from the 25 mm. of small minor to the 90 mm.
of cheiranthi and in my opinion the name is illogical and ill-applied since,
as defined by Verity (translated): “gigantic with an expanse of 62 to

36 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

66 mm. and the length of the hindwing from 55 to 36’. Unfortunately
the parameter of measuring are not given. Never-the-less I have a complete
range of specimens going up to 90 mm. and many normal British examples
are of the size quoted by Verity.

The size of brassicae appear to vary according to two factors. First, it
would seem to be genetic in some cases. For instance all pure bred race
cheiranthi reared by me are larger than typical brassicae. The hybrid is of
intermediate size, and the F.2 generation produces a range of size, which
are quite clearly coupled with the wing markings: — the larger specimens
with the most cheiranthi-like facies and the smaller specimens the more
typical brassicae facies.

The size of the adults can also be varied by environmental factors, those
being reared at low temperatures and low densities, (10-15°C) being
markedly larger than those reared at 25-30°C and high densities.

marginata Graham-Smith and Graham-Smith (1929)

This has a band of black scales running along the costa and termen of
the upper surface of the hindwing. According to the Graham-Smiths’ it is
particularly prevalent in brassicae from the Eastern half of its range but
certainly also occurs in European examples, but not cheiranthi. It is
confined to the male and appears also to be associated with nigronotata.
It is of course always present in the related species P. deota Nicér and
P. brassicoides Guérin.

marginavenata McLeod (1968)

This variety originated in a sub-division of the Cambridge stock. It is
characterised by the veins on the under-side of the male hindwing being
stressed by borders of black and grey scales tapering towards the margins.

maria Mellaerts (1926)

As described by van Mellaerts this varity has the two dots in the female
joined by a sprinkling of black scales. It does not also have the dots
joined to the apical blotch and since the type of facciata does have all
three black areas so joined, it should be considered a separate variety and
I cannot therefore agree with Lempke’s suggestion (1953) that the name
is illogical and should fall as a synonvm of fasciata. This variety is quite
common in the various cheiranthi hybrids that were produced and continues
to appear in the cheiranthi hybrids strain still maintained at the Glass
House Crops Research Institute, Littlehampton and was also common in
the Hereford stock.

minor Ksienchopolsky (1911)

The name applied to small specimens. It has already been shown that
this variety is environmental, being produced by semistarvation of the
larvae (Gardiner, 1963). Never-the-less extra small larvae are sometimes
noticed in a batch of normally fed healthy stock. Attemps have been made
to rear these but without any adults being obtained. Usually the larva dies,
but three or four chrysalids were obtained, very small, one of which
weighed only 98 mg. (normally 300-400 mgm.). All died. It is therefore
just possible that some of the minor in collections originated from such
small larvae and not from the more probable cause of semistarvation. Un-

suitable food, such as Dutch pride cabbage, may also produce these speci-
mens.

meridionalis Rocci (1919) (Fig. 25)

This is another pale form of brassicae localised in Italy. Again I believe
this to be another manifestation of environmental factors as such forms
appear from time to time in the Cambridge and virus-free stocks.
nana Rocci (1919)

Is a synonym of minor Ksienchopolsky (1911.
nepalensis Gray (1846) Fig. 23)

This is the Himalayan race, and is sufficiently isolated by mountains and
desert to avoid internal or external migration from its range. It is
charcterised by having more extensive black areas than the nymotypical
but these are extremely variable and some examples are not separable from
type. In particular, however, it shows a marked percentage of marginata
and strigata. In addition fasciata and nigronotata are often present.

I have no experience of breeding this race. It is known to be sometimes
a pest on cabbage crops but I suspect it has other foodplants. Some of the
Hereford examples bred by me were similar, as indeed have been some of
the cheiranthi hybrids, and I have no doubt that nepalensis is controlled by
multiple alleles and that, having such a wide area of distribution (unlike
the Island races) there has been less opportunity to stabilize into a uniform
pattern of facies.
nigrescens Cockerell (1889)

Bramwell (1869) described a black specimen thus: “It is a female and is
of a uniform black dusky colour, both on the upper and undersides; the
black spots on the wings are quite distinct being of a much more intense
and shining black than the ground colour’. The Graham-Smiths (1929-30)
introduced the name semi-nigrescens and basi-nigrescens for partial (as
opposed to uniform) dusky brown colouring on the wings and both Gardiner
1974 and Wilde 1957 carefully avoided creating new names for their
specimens wihich did not fit the descriptions of the above three forms. Care
also needs to be taken to distinguish nigrescens in which the scales are
grey in colour (Gardiner 1974) from specimens in which the scales are
malformed being upturned at their edges and have a ‘mealy’ or ‘shaggy’
appearance, which gaves the same effect through optical illusion as does
the grey colour of true nigrescens. I have examined the type of semi-
nigrescens and it is of this form. The type of basi-nigrescens is, by
designation, the specimen captured by Plant in 1843 of which there is a
good colour illustration in Morris 1857, and it certainly appears to be due
to grey scales as in true nigrescens. We therefore have the situation where
nigrescens and semi-nigrescens are due to different causes.

I have had a number of examples of the ‘mealy’ or ‘shaggy’ variety all
of them amongst broods of the recessive varieties coerulea and albinensis.
In no sense can they be referred to nigrescens nor do they show colouring
called for in the description of the type basi-nigrescens by the Graham-
Smiths. It is quite clear to me that these ‘mealy’ examples are due to
faulty eclosion, and would be better not named. To return to nigrescens,
the Graham-Smiths describe the variety this: ‘The parts usually white are
dark, greenish grey on both upper and underside, while the usual dark
markings are distinct’. They figure a completly black suffused example.
They then go on to say that “Cockerell (1889) gave the name to a female
captured two miles from Perth in 1868 and thus described by Bramwell”
(Bramwell, 1869). But this is just what Cockerell did nor do. In his article
on the variation of insects most of his definitions are the briefest of the
brief and his full statement as regards brassicae is as follows ‘Pieris
brassicae nigrescens, Newman, Brit. Butt., 165”. If we now turn to New-

38 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

mans book (Newman, 1868) we find on page 165. “At page 471 of the
second volume of the ‘Zoologist’, Mr. J. Plant of Leicester, figures a variety
of this butterfly with a sharply defined black patch at the base of all the
wings. At p.258 of the fourth volume of the ‘Entomologist’? Mr. J. M.
Bramwell of Perth mentions that he has in his collection a female and of
a uniform dusky black colour’. Plant’s specimen must obviously take
priority over Bramwell’s and since we have both male (Plant 1844) and
female (Bfamwell 1869) the former is by designation, due to line precedence
the type, and the latter the neallotype. This interpretation has the great
advantage of leaving nigrescens as a variety subject to considerable varia-
tion and therefore capable of accommodating the partial dusky specimens
which have been reported by Gardiner and Wilde. Var. basi-nigrescens
consequently falls as synonym of nigrescens. This variety is obviously of
great rarity and is most likely due to a fortuituous mishap in early cell
division which concentrates some black scales where they do not normally
occur. The only recent specimens known to me are those of Wilde (1957)
from Germany and my own from the Cambridge stock (Gardiner 1974).
This last was partial and had the effect confined to one side. There are in
the British Museum (Natural History) several specimens with areas of
intense black scaling, but they cannot be strictly be referred to nigrescens,
although I feel they are due to the same cause.

nigronotata Jachontoyv (1903) (Figs. 3, 4)

In this variety there is a streak or oblong patch of black scales on the
upper side of the male forewing between nervures 3 and 4 and just terminal
to the discal cell. Although described from a Western Russian specimen
this form of male is the most usual in brassicae on the edge of its range,
particularly in the races cheiranthi, wollastoni and nepalensis. It was
recorded as present in 1.7% of the specimens from Aberdeen by the
Graham-Smiths. I have never come across this variety in either Cambridge
or virus-free stock. It occurred amongst the cheiranthi hybrids however,
as One might expect, and also commonly in the Hereford stock. The extent
of the black is quite variable, from a few black scales, just visible, to a
very prominent and intense black streak. Its shape is invariably different to
the round or square dot found in the female. Its concentration in isolated
races and occasional appearance when it breeds true —from time to time
elsewhere leads me to conclude that it is due to a combination of two or
more alleles.
nigropunctata Walcourt (1920)

It is a synonym of posteromaculata Verity (1911).
nigroviridescens Rocci (1919) (Fig. 14)

In this variety the underside of the hindwings are densely suffused with
black scales giving a very dark appearance. The name anthrax Graham-
Smith and Graham-Smith must be considered a synonym. This is yet another
case of its being impossible to say where one variety begins and the next
ends, pallida dissolves into type into venata into nigroviridescens. The
colouring of the brassicae underside seems to be dependent on locality and
I would like to put forward the suggestion that it is due to selective pres-
sure by predators. For instance cheiranthi has a very light yellow-buff, some
examples almost orange, in colour with virtually no strewing of black
scales. It feeds only on Tropaeoleum (Fernandez, 1955) in the Canary
Islands, and when settled amongst this foodplant or feeding from flowers of
the island flora, it really is an inconspicous insect, whereas a dark under-
side would stand out amongst the green and the yellowing leaves of

PROC. BRIT. ENT. NAT. HIST. soc., 1979 39

Tropaeoleum. Specimens I have from Malta and Spain, however, are
mostly of this variety and so too are those from Chile. I have already
(Gardiner 1974b) put forward the theory that this dark underside colour
is due to pressure from predators and more suited to the survival of
brassicae in its new environment of South America.

obenbergi Tykac (1947)

Described from a summer brood example, this variety has the ground
colour fundamentally of a yellow colour but the apex grey and the under-
side “light green’? powered black with the veins brown. I have not seen
the type and can only conjecture that it does in fact differ from flava with
which it might perhaps be confused from the description given.
obscurata Oberthur

Oberthur stated it had all the wings of a dusky dark grey. As described
this is a synonym of nigrescens Cockerell (1889) as redefined in present
paper.
ocellata-loberi Kraut (1938)

Described from a female which has the upper discal spot of a steel blue,
or light blue with a dull silver sheen, appearing as a metallic “eye” with
a black border, giving to the insect an exotic appearance. I have not seen
this specimen, nor come across another example. I am inclined to the
belief that it is due to some mechanical defect in the scales.
ottonis Rober (1907)

This name was given to spring specimens from Fergana but Verity (1908)
illustrated such specimens and was of the opinion there was “no reason to
distinguish them particularly’. I cannot separate these from other spring-
form chariclea either and the name is therefore a synonym of chariclea.
pallida Graham-Smith and Graham Smith (1930) Fig. 11)

As described “The undersides of the hindwing and of the apical areas
of the forewings are pale, lacking to a great extent the yellow colour
normally present”. In most cases in the spring generation, the black pig-
mentation commonly present on the hindwing is slightly developed. This
variety is simply one end of the range varying from very pale to very dark
colouration of the underside. It occurs from time to time in all my stocks
and has already been commented on under nigro-viridescens.
parvomaculata Rocci (1919)

In the female the upperside spots not larger than those of P. rapae and
the apical mark pale grey. Several such examples have appeared in the
Cambridge stock. No two are quite alike and some (although they cannot
strictly be called this name), having only one, it may be either, of the
spots reduced. It should not be confused with the very pale examples
sometimes produced by environmental conditions, as it is part of the
multifactorial complex covering spot size and intensity.
perflava Lempke (1953).

As described ‘Ground colour of the underside of hindwings and the
apex, of the forewings deep yellow’. Lempke (1955) knew only females of
the spring brood. I have had examples of cheiranthi and brassicae/
cheiranthi hybrids such as described but tending rather to orange par-
ticularly along the costa of the hindwing. It seems probable that this is a
more extreme form of pallida. It does not, however, appear to be jauni
with which it might perhaps be confused.
plasschaerti Dufrane (1912)

Ts a synonym of venata Verity (1908), see below.

40 PROC. BRIT. ENT. NAT. HIST. SOc., 1979
postice-ochreata Verity (1919)

This name is applied to first brood females of Northern races (including
Britain) which have the upperside of the hindwing a bright ochreous colour.
It also occurs in summer brood specimens at times and is part of the
series from almost dead-white to nearly orange that occur. It is not possible
to say where this variety begins or ends.
posteromaculata Verity (1909)

Verity’s original description is “Il est intéressant de remarquer que chez
la 2 on rencontre quelquefois une forme ayant une tache noire sur le
disque des postérieures correspondent a celle qui est constant chez deota
et qui s’observe quelquefois aussi chez la 2 de P. manni forme rossii,
ainsi que chez P. napi forme napaeae et trés rarement meme chez rapae;
le nom de posteromaculata (page 331) proposé pour napaeae doit, 4 mon
avis, servir pour toutes ces espéces’’.

The french word ‘tache’ should be translated as ‘spot’ whereas in the
two specimens illustrated by the Graham-Smiths only a light speckling of
black appears and while this variety is clearly not too uncommon, the
degree of black present varies to a large extent and perhaps only when
the black spot is as clear as it is in P. deota de Niceville, should the name
be applied. This variety has in fact only occurred with me in a few females
of brassicae/cheiranthi hybrid broods.
pseudocataleuca Rocci (1929)

Another local form named from specimens obtained on the Tuscan
Appenines in Italy. Again environmental; variable from year to year and
grading into other forms, it occurs in both Cambridge and virus-free stocks.
punctigera Graham-Smith and Graham-Smith (1930)

As mentioned by the Graham-Smiths this variety is sometimes seen in
Himalayan specimens. I too have only seen it in examples of race nepalensis.
It is characterised by having black spots or radial streaks on the upper
surface of the hindwing. This patterning is normal in the related P. deota
Nicér,P. canidia Sparrm, and P. brassicoides Guérin.
rammei Knop (1923)

In this variety the apical blotch is traversed by the nervures traceable as
four yellow-brown streaks. The Graham-Smiths quote several examples and
go on to state that recently emerged specimens can rub the tips of their
wings in such a manner that rammei is simulated. I have examined several
such specimens under the microscope and the normal black scales are
lacking or very sparse in the streaked area.

I have a few examples, in particular a rather striking one from Chile.
All were noticed postmortem and all give me the impression of being
artificial in some way. I am of the opinion therefore that this variety is
due to some environmental factor, possibly difficulty in clearing the pupal
skin causing rubbing or perhaps a haemolymphal leak towards the ends of
certain nervures. This opinion is confirmed by the fact that by very carefully
rubbing the apical blotch of fresh specimens between finger and thumb,
examples referrable to rammei can be produced.
radiata Rober

I do not have any information on this variety.
reducta Fritsch (1913) (Figs. 26, 29)

In this variety the lower discal spot in the female is absent. Although
not so stated in the orignal description, all the examples I have seen have
the black absent on both upper and underside of the wing. Generally, but
not always, it is accompanied by a reduction in size and intensity of the
other black markings. I have a series of transitional forms collected over

from cheiranthi hybrid stock.

semi-nigrescens Graham-Smith and Graham-Smith (1930)

As defined by the Graham-Smiths and as already mentioned examples of
this variety are due to mechanical deformation of the wing scales and
there is no relationship with nigrescens. Examples with such deformation
occur from time to time in all stocks except the cheiranthi hybrids and
are particularly prevalent combined with vars. coerulea and albinensis
separata Pionneau (1928)

Described for a specimen where on the underside of the forewing the
lower discal spot is divided into two parts. From time to time examples
occur where one or other of the discal spos, either on the upper or the
underside is divided into two distinct halves by a band of white scaling.
There is insufficient evidence to show whether it is due to some mechanical,
genetic, or environmental effect or is a true genetic abberation.
striata Rocci (1919) (Fig. 20)

In this variety the apical blotch is joined to the upper discal spot by lines
of black scales along the nervures 3 and 4. This variety is very common in
races wollastoni, nepalensis and cheiranthi. It often appears from time to
time in specimens from many localities and is frequently but not invariably
associated with fasciata. Its extent also can vary from weak black tracery
along the nervures to a complete solid black bar confluent between the
apical blotch and black spot. This variety was common among _ the
cheiranthi hybrids and the Hereford stock but I have not otherwise bred it.

The variety is clearly part of the multifactorical complex governing the
extent and size of the black markings. I consider biligata Cabeau (1925)
to be a synonym.
sublutea Turati (1924)

In this variety the black scales which are normally present at the base
of the wings on the upper surface are absent. It was originally described
from examples of the race cyniphia, but is not present in any of these in
my possession or seen by me, including examples from Cyrenaica. In
specimens with much reduced black markings generally the black wingbase
scaling is also much reduced and of course ab. albinensis and coerulea also
lack the black scaling, but for other reasons.
supra-fasciata Graham-Smith and Graham-Smith (1929) (syn. nov.)

Neither Lempke (1953) nor I agree that this form really exists as we have
never come across a specimen. The type is not among the Graham-Smiths
material in my possession. As already stated earlier, and in view of the
doubt created by a re-examination of the type of infra-fasciata, I consider
the name should be sunk as a synonym of fasciata.
teratological specimens (Figs. 31, 32, 34)

From time to time specimens of insects are found in which the anatomy
is some way abnormal. I have one specimen of brassicae in which the
abdominal segments are twisted, with one of them being wedgeshaped. This
was first noticed in the larva and can now be seen best in the cast chrysalis
skin. Many other examples have occurred in which the wings are distorted.
Similar effects can be produced by deliberate mechanical damage to the
appropriate area on the chrysalis and the appearance of many of the
examples lead me to the conclusion they are due to constriction and pres-
sure on the wingbud area by the silken retaining girdle spun by the larva.

In some specimens the wings are larger on one side. While this could be
explained by other causes an equally valid explanation is the similar one of
mechanical damage affecting the full functioning of the expansion
mechanism.

tertia Verity (1919)

Created to describe third brood examples (which occur particularly in the
Mediterranean region) and is described as midway in appearance between
2nd and 4th broods. In view of the variability of facies according to seasonal
and climatic variations it is not possible to separate fertia with any
certainty from either typical or catoleuca (2nd brood).
trimacula Rocci (1919) (syn. nov.)

This name was erected for those examples in which both fasciata and
striata were present. It should be borne in mind, however, that Kieffer’s
illustration of the type of fasciata is also striata; that is to say, the apical
blotch is joined to the costal dot, as well as the two dots being joined
together with black scales. The name is therefore a synonym of fasciata.
ultimogenata Verity (1909)

This was sunk as a synonym of autumnales Rocci (1919) by Verity in
later work (Verity, 1947).

In this variety the apical blotches are very pale, being ashy-grey in colour.
The effect is produced by a quantity of the normal black scales being
replaced by white ones. Although apparently common in the spring broods
from Southern Europe (Verity 1916) I have a few summer brood examples
from the Cambridge stock. Verity (1916) who originally figured an example
in Rhopalocera Palaeartica, then considered it the culminating form of the
spring brood generation. It is of course very similar to chariclea. I concur
with Verity that it is the culminating form of the spring brood, and further,
I suggest that it may be due to the environmental cause of the chrysalis
being subjected to a mild winter.
venata Verity (1908)

In this varity the underside basal area of the wings are distinctly dusted
with violet grey scales. In the female this occurs on the upperside also.
Named by Verity to cover examples from Morocco, where it appears to be
the normal form. It has also been seen occasionally in specimens from
other areas and I have two examples from the Cambridge stock. The
specimen shown in Fig. 21 from Morocco does not meet Verity’s descrip-
tion.

I would suggest that this is another manifestation of the background
colour change which takes place in response to predator pressure and then
stabilises. The suggestion that the explanation could be that the violet is
produced by the exceptionally strong sunlight of North Africa is rather
unlikely since similar violet tinged specimens do not seem to have to have
been recorded from Cyrenaica or Palestine.
wollastoni Butler (1885)
verna Zeller (1847)

Graves (1925) considers this second generation form to be a synonym of
aestiva Zeller and Verity (1947) agreed with this view.
vasquezi Oberthur (1913) (Fig. 7)

This is the race from Madeira. The black markings are not so extreme as
in cheiranthi but the race is characterised by being strongly ab. fasciata
and the underside is undoubtedly darker and greener than in nymotypical
specimens. The larvae are the same. I have bred this race but was unable
to obtain cross pairings to other brassicae. Race wollastoni would appear
to be due, as I believe has happened with cheiranthi and is happening in
Chile, to selective pressure of predators stabilising the facies to fit in with
their surroundings and I suggest also that the original introduction took
place only a few hundred years ago.

Discussion

Variation in P. brassicae falls into four main groups: (1) Those in which
there is a major colour change and which is controlled by a recessive allele;
the varieties coerulea, albinensis and probably fllava fall into this category.
(2) Those in which the amount and intensity of the black markings varies.
These I consider to be controlled by multiple alleles but to be capable of
modification by environmental factors. (3) Those in which the underside
colour varies. This I consider to be due to multiple alleles but again
modifiable by environmental factors. (4) Miscellaneous variation which may
be due to various other factors not at present fully understood. In this
group I include gynandromorphs, nigrescens, pink, brown or grey apical
spots which turn up at random but of which there is certainly some evidence
that they are due to chance mechanical or unusual environmental con-
ditions.

Throughout its range the first brood of the year which is derived from
diapausing pupae, differs from later broods derived from pupae of short-
lived duration. It is lighter in colour (due to less black and more white
scales) on the upperside, but darker in colour on the underside of the
hindwing. Imagines derived from pupae weakly in diapause tend to have
the first-brood underside facies, but non-diapause type upperside. By
splitting of eggbatches and rearing under the appropriate conditions it is
possible to have all three forms in the sibs of one pairing. It is quite clear
therefore that the first or spring brood of the year (chariclea) is environ-
mentally controlled.

In addition to this spring form, various authors have considered that
second third and fourth broods are also deserving of a separate name. In
addition to these a considerable number of local forms have also been given
a name. There is absolutely no doubt that, over its range, the facies, does
vary considerably, in size intensity of the white background colour, intensity
of colour of the black spots, and also the colour of the underside of the
hindwing. But is this variation enough, or constant enough, to justify so
many names being used? I think not. P. brassicae is a noted migrant.
Except therefore at the extremes of its range, where geographically isolated
populations occur, there is a constant intermingling of all these local forms.
This could well explain why there has been, indeed still is, so much con-
fusion and synonmy concerning them. Many of these forms have been
illustrated by various authors (R6ber 1907; Verity, 1907; 1947). If we take
a quantity of ova laid by an individual of my Cambridge stock brassicae
and rear them under a variety of different conditions, then the resulting
imagines will fit the description or illustrations to most of these local named
forms of brassicae. When I rear brassicae from distant locations in Cam-
bridge they too vary with the conditions of rearing rather than fitting in
with the named form from the area whence they came. (This does not
apply to isolated races, like cheiranthi, which are genetically controlled and
are discussed below). In any particular area too, over a period of years,
even when the climate is relative stable and constant, there will be a period
of exceptional weather and the brassicae facies will change from what it
normally is in that area. This, coupled with migration, explains the con-
fusion over local forms in the literature and indeed perhaps explains why
a name was given, for I believe that some local forms were named (alpina
for instance) because it was noticed they were different from usual and it
could well be that this difference was caused by exceptionally abnormal
climatic conditions in a particular year or two in that area. That such

44 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

plasticity is inherent in brassicae is confirmed by both the Cambridge and
virus-free stocks, bred under varying conditions as they have been, pro-
ducing so many of the named forms.

At the geographically isolated extremes of its range we have, however,
other conditions prevailing. There is no migration. There may well be
selective predation pressure not apparent elsewhere. We have already seen
in the Aberdeen material studied by the Graham-Smiths (Graham-Smith and
Graham-Smith 1930) and more recently in the Hereford stock, how other-
wise typical British brassicae can suddenly turn up specimens half-way
towards race cheiranthi; and it has been shown (Gardiner, 1973) how
selection of breeding adults can lead further towards cheiranthi (or indeed
vice-versa). Once established such genetic combinations of multiple alleles
will breed true, the more so if there is good cause for this particular com-
bination to have some selective advantage.

Again with the underside colour. This clearly is modified by climatic
factors as can be seen from chariclea and weakly dispausing specimens.
Never-the-less in certain areas light or dark forms of the underside do
predominate. The most likely explanation of this is again selection pressure
of predators. The light yellow underside of cheiranthi fits in so much better
with Tropaeolium foilage than it would or does—on cabbages. This is,
however, something that requires much further investigation and again,
apart from the geographically isolated races, there must be a constant
mixing of the genetic combinations brought about by migration. Since it
appears that most migration takes a northerly direction one would expect
brassicae at the south of its range to show a more stable facies. In the
specimens looked at by me this appears to be the case.

ACKNOWLEDGEMENTS

The number of people who have helped me one way or the other with Pieris
brassicae over very many years is very large indeed. To all those who may
remember doing so, very many thanks. In particular, however, I feel I should
thank Sir Vincent Wigglesworth for allowing the use of rearing facilities at the
ARC Unit of Insect Physiology and my colleague Dr. W. A. L. David for his
interest and help. The drawing of the illustrations was by Mr. John Rodford.

OCYUSA NITIDIVENTRIS (FAGEL) (COL., STAPHYLINIDAE)
NEW TO BRITAIN
by S. A. WILLIAMS
(79 Cedar Drive, Sutton at Hone, nr. Dartford, DA4 9EW, Kent)

In 1965 Dr. R. O. S. Clarke gave me a specimen of Ocyusa that he
was unfamiliar with. It was collected from under a stone at Ringinglow,
near Sheffield, on 6th November 1964. It was unknown to me and not
referable to any British Ocyusa, but eventually after much correspondence
with entomologists and institutions in this country and abroad, it was
determined as Ocyusa nitidiventris (Fagel). This insect was first described
from specimens collected in Spain (Madrid and Castille) and was originally
placed in the genus Cousya (Fagel, G., 1958, Bull. Ann. Soc. R. Ent. Belg.,
94, IX-X: 247-8).

In addition to Dr. Clarke’s specimen, I have now seen examples of
nitidiventris from four more localities in Britain (and three localities in
West Germany) as follows: Oxford, Washford, 26.v.1925, 1 ex. (Cameron
coll.); N. Devon, Braunton Burrows, iv.1928, 1 ex. (K. G. Blair); Kent,

PROC. BRIT. ENT. NAT. HIST. soc., 1979 47

Maidstone, 30.v.1975, 6 exs. in pitfall traps at Lees chalk pit organised by
The Institute of Terrestial Ecology and Mr. E. G. Philp; London, S.E.7,
Charlton, 14.v.1977, 1 ex. (A. A. Allen) at the roots of herbage on dry
heathy ground above the old sandpits. From the evidence available it
appears to favour dry habitats on well drained soil.

When compared with other species of the genus, nitidiventris is readily
recognised by its general, rather narrow appearance and in particular by
its strongly convex pronotum, which is clearly narrower than the elytra.
However, such a comparison is made difficult by the rarity of O. defecta
Mulsant and Rey and nigrata (Fairmaire and Laboulbéne) which are
unfortunately the two insects that it most closely resembles (particularly
nigrata). O. defecta, for instance, has only been taken twice in Britain
and for the present work it proved easier to obtain continental examples.
Specimens of nigrata are easier to refer to as there are a few in the British
Museum (Nat. Hist.).

O. nitidiventris is readily separated from the remaining two species in
the genus maura (Erichson) and hibernica (Rye). O. maura has the fourth
antennal segment longer than broad, whilst in nitidiventris it is transverse
or at the most quadrate, also the punctures on the pronotum are much
closer than on the elytra, whilst in nitidiventris they are more diffuse. The
long hind tarsi will readily distinguish hibernica. The male of nitidiventris
has the eighth sternite prolonged a character shared with hibernica.

I have not had sufficient material to study the genitalia of all the critical

species, however in the single female of nigrata that I have been able to

examine the spermatheca is very similar indeed to that of nitidiventris.

CHANGES IN LONDON’S INSECT FAUNA
IN THE LAST 100 YEARS
by ALAN E. STUBBS

(Nature Conservancy Council, 19-20 Belgrave Square, London SWIX 8PY)

When invited to contribute to a London Natural History Society sym-
posium on this theme in 1976, my preparation soon made me realise how
little information was readily available beyond pure guess-work. I found
myself speaking of a major city which, for well over a century has had the
greatest concentration of active field entomologists anywhere in the world.
Generations of us have our interest kindled, often in our youth, by the
fascinating creatures we found sharing our urban existence, and have
developed our knowledge of them by studying the insects on our door-step.
Yet past generations have left us a very inadequate record.

As a Society our records, as at field meetings, focus on the countryside to
which we escape, though the ‘field’ begins in our garden or even within our
houses. The topic seemed eminently suitable for a discussion-meeting; it
took place in the Society’s rooms on March 24th 1977 and our official
Proceedings (10: 108) gave it a bare three lines; but the contributions I
hope, deserve a fuller, permanent record. There has been a growing feeling
within the Society that some such meetings should be reported in our
Proceedings for the benefit of both full and country members.Whilst those
of us living in London sometimes envy people in the country, perhaps at
least we can show them that the capital is an interesting place for the
entomologist.

PROC. BRIT. ENT. NAT. HIST. soc., 1979 49

The opening address was directed at inner and true suburban London
and has here been supplemented by detail left out of the talk. The discus-
sion ranged into the countryside fringe, generally keeping within the
L.N.H.S. 20 mile radius of St. Pauls. Contributions have been rearranged
to some extent to keep themes grouped together and some of the discussion

OPENING ADDRESS ILLUSTRATED BY SLIDES

London, even inner London, is not without a great deal of interest and
one can readily think of other cities and urban areas where the entomolo-
gical interest may be much poorer. The nearest most Londoners get to
realising the existence of insects is seeing a show case of tropical butterflies
for sale in Knightsbridge, yet little does the general public realise that
large spectacular native insects thrive within the heart of the capital.

Thinking back to the London of 100 years ago, the greatest change we
would notice is that the horse was the main means of transport on the
streets. We can still see the old stables, now converted to garages and flats
in the mews behind impressive frontages of Victorian buildings. There must
have been many interesting insects in and around horse manure and hot
straw. We seem to have no record, but Mr. E. Bradford has suggested that
the micro moths Pyralis farinalis (L.), Hypsopygia costalis (F.) and Tricho-
phaga tapetzella (L.) should have been common yet now they are rarities.
The few central London stables are no doubt rather too hygenic nowadays.

Our own homes and gardens provide a major sanctuary for insects.
With growing hygiene conciousness and our use of DDT and other
insecticides, the insects in our homes may have decreased. It has been said
that the flea suffered a major setback with the introduction of the vacuum-
cleaner in the 1920’s since the eggs and larvae were less successful in
escaping attention in carpets and crannies. The bed-bug is now a rarity
though I have not heard any hemipterists bemoaning the fact. The house
fly, Musca domestica L., which as late as the 1940’s and 50’s was presented
as the scourge of mankind is in relatively low numbers in most parts of
London today. Perhaps the DDT campaign assisted in the decline, but my
own childhood memory was that such flies, though possibly not this species,
were abundant in the house in the post-war era of keeping chickens in
our garden, and their decline was rapid once this form of mini-farming
ceased.

Gardens are of many different ages and types and the variety of
building development in and around London must contribute to the diversity
of insects. My own garden in Hanwell, Middlesex, was of the 1920’s era
yet only a mile away friends with late 1800’s gardens were getting very
different moth faunas in the mid-1950’s. Within central London, the
garden of Buckingham Palace has yielded many interesting insects, includ-
ing 500 species of lepidoptera. Among the many native moths, Dr. J.
Bradley has recorded additions to our London fauna such as Monochroa
hornigi (Staudinger) found nowhere else in Britain and Caloptilia azalela
(Brants) which established on the Azaleas in 1972 and is otherwise only
known on the outskirts. However, most Londoners have modest estates
but because of the limes in the streets and the sorts of trees and plants in
our gardens, even the general public stumbles across Lime Hawk Mimas
tiliae (L.), Privet Hawk Sphinx ligustri L., Eyed Hawk Smerinthus ocellata
(L.) and other large exotic-looking species, besides a wealth of small insects
which often remain unseen and unrecorded even by entomologists. The

50 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

sorts of plants which are popular with gardeners must fluctuate enormously
over the years and this in turn must affect the occurrence and abundance
of certain species. Larkspur is currently quite popular and it supports the
Golden Plusia moth, Polychrysia moneta (Fab.), first recorded in London
in 1892 after its discovery as a British species in 1890. The leaf-mining fly
Phytomyza aquilegiae Hardy on Aquilegia is locally common, yet native
wild plants are rare in the countryside around London.

Modern housing design is often not only devoid of human values but
also of insect values as well. The tower block with its surrounding mown
jawns is an impoverished area for insects. The open-plan front lawns of
modern housing estates also lack the character of former London suburbia.
As land values rise, there is increasing pressure for the grounds of large
houses to be broken up as small housing lots for office blocks and other
developments. Thus the character of London is changing, and the insects
often lose out.

One should not forget communal gardens in the form of allotments. These
have been a major feature of suburban London. Since the second world war
there has been a decline in their use so that many acres of wilderness were
available to insects. By the late 1960’s they were being sold off as building
plots but the down-swing in the state of the nation’s economy has encouraged
again a renewed enthusiasm for cultivating allotments.

The use of insecticides since the war must have had a profund but
unknown effect. To some extent the layman now realises that destroying
predator as well as pest is not a good thing and manufacturers are becoming
conscious of the need to make safer and more specific sprays.

Our squares and parks are a famed feature of London. Many of these
areas must have changed enormously over the last 1CO years. We are now
familiar with the mown lawns, even for an area the size of Hyde Park,
and many exotic trees and shrubs are planted. Some of the introduced
plants are virtually useless to insects, for instance the London Plane is
renowned for the Vapourer Moth, Orgyia antiqua (L.), and (*) little else,
but other introductions such as the Lombardy Poplar have been readily
colonised by a rich native fauna including large species such as the Poplar
Hawk,Laothoe populi (L.) and Puss moth, Cerura vinula (L.). Innumer-
able species have colonised London because of the very artificial conditions,
including for instance the hot house and other insects at Kew Gardens.
Waste ground is a widespread feature within London, but its abundance has
varied and seems to be declining. The bomb sites of Cripplegate were
surveyed by London Natural History Society and as a result there is a
record of the rich variety of insects which took advantage of new patches
of weeds; the Elephant Hawk, Deilephila elpenor (L.) was one of the more
spectacular species to become abundant. The environment was, however,
a demanding one with high temperatures and arid conditions such that
sawflies and various other insects did not establish themselves in the same
variety as Lepidoptera. Apart from temporary sanctuaries on idle building
sites there are fewer such opportunities now. Until recently rubbish dumps
were widespread in the suburbs and provided excellent places for both plans
and insects; species such as the House Cricket, Acheta domestica (L.),

|*Acronicta aceris (L.) was also characteristic before world war one, but has
survived in Inner London less well than the tree.—Editor.]

PROC. BRIT. ENT. NAT. HIST. Soc., -1979 51

were locally abundant. In recent years less land-demanding forms of waste
disposal have become employed and our tips are often grassed over to
make way for football fields and other uses. However, despite this decline,
waste ground is still plentiful in the suburbs to anyone prepared to search
out odd corners.

London has undoubtedly gained many species over the last 100 years and
several species have already been mentioned. Some reflect a general
establishment in the south-east. For instance the Scots Pine is said to have
been an introduction into southern England early last century, so now
with pines planted in London, the Pine Hawk, Hyloicus pinastri (L.) has
established itself. However, in other cases one does not know whether
there is a loss or gain, as with the various flies and beetles associated with
large mammal burrows. The rabbit has declined and is now mainly a
surface dweller but the fox has in recent years become strongly established
and to a limited extent provides another set of burrows. Rabbit fleas are
presumably scarcer.

Some of the gains have used London as a springboard for invading other
parts of the country. Mr. P. Hammond has already spoken to the Society
about such introduced beetles as Aridius bifasciatus (Reitter); it is possible
to produce maps with rings around London showing the dates of its
progressive radiation outwards. The case of the Waved Black Moth,
Parascotia fuliginaria (L.) is less clear. It was first found in London Docks
and later turned up on previously well-known heathlands in Surrey and
more recently further afield. Whether this is a real spread or simply
lepidopterists getting their eye in is difficult to say. Some additions to
London’s fauna have been through taxonomic advances and the realisation
that one species is in fact two. Undoubtedly there have been losses; but
these are not always easy to prove. The Great Green Bush Cricket,
Tettigonia viridissima L. once lived on Battersea marshes, and we have
certainly lost it, perhaps in this century. Species living in ponds and canals
have lost much of their habitat due to infilling, pollution and over-
enthusiastic amenity management, including overstocking with ducks and
fish. The London Naturalist compilation of dragonfly records published in
1948 has been well outdated by further declines.

We are today witnessing one of the most serious natural losses, which
could not have been predicted even 10 years ago. The Elm, such a dominant
feature of many parts of London and its suburbs is seemingly doomed by
dutch elm disease and with it the rich fauna it supports. The White-letter
Hairstreak, Strymonidia w-album (Knoch), which at last has become
common in parts of the London fringe has its days numbered. The White-
spotted Pinion,Cosmia diffinis (L.) and Lesser-spotted Pinion, C. affinis (L)
occur well within London, and these too have no other foodplant. The
nationally rare hoverfly, Mallota cimbiciformis (Fall.) was known to have
been breeding in elm rot holes in Hyde Park in 1953 and may well have
continued until the elms were removed. In some parts of London the Stag
Beetle, Lucanus cervus (L.), has been thriving on elm, so local decline may
be imminent though fortunately in some other areas of London it must be
dependent on other trees. The only hope for the foliage-feeding species
is to adapt to the small sucker growth which locally remains and is
apparently able to withstand the disease.

There are species which have become adapted to London. Perhaps this
is a common feature at an unrecognised physiological level but it is easiest
to appreciate with so-called industrial melanism. The Peppered Moth,

52 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

Biston betularia (L.) is the best known example, but there are of course a
number of other moths with the same genetic trait. There seems to be no
record of the date of first appearance of black Peppered Moths in London
but it may well have been about 100 years ago.

Some gains are transient. For instance, the migrant butterflies appear in
greater or lesser numbers from year to year. Others may or may not be
here to stay, such as the Speckled Wood, Pararge aegeria (L.), which in
the last few years has appeared even in St. James’ Park. Examples of the
latter type may simply be a reflection of a good summer or two, since in
1976 Meadow Brown, Maniola jurtina (L.), and other butterflies have
appeared in gardens where they were not seen before.

It is tempting to look forward into the next 100 years but we can probably
no more predict the appearance of London in the year 2077 than could
the first members of our Society have forseen the nature of London today.
We can, however, suggest future trends which we regard as useful and
perhaps influence planners and others who are beginning to think in terms
of urban conservation. We know that we would like to see our few remain-
ing wild inner London commons remain wild rather than be reduced to
mown lawns with a few planted exotic trees. The trees that are planted in
parks should include native species and if they are to be exotic, then why
not those which will support a wide range of interesting native insects such
as the Lombardy Poplar. At last planners are questioning the wisdom of
tower-block planning, with associated sterile lawns, and we would no doubt
wish to associate ourselves with those who prefer more traditional housing
with gardens. The provision of wilderness-areas for playgrounds and walk-
ing, instead of a monotonous green carpet, seems sensible and can we not
have a more natural treatment of ponds and lakes? To keep Britain tidy,
at vast public expense, may not always be necessary or even desirable, and
is detrimental to wild flowers and those interesting beasties associated with
them. Many children are encouraged to find interest in the insects of a
fantasy nursery world, yet it is only a few of us who keep that interest
alive into the real world of creatures of equal fascination around us. Since
future members of the Society will often be brought up, and live the rest
of their livs, in urban areas, perhaps we should ensure that London, and
other places, in which we live and work, do remain fascinating places for
the entomologist.

DISCUSSION

Mr. C. O. Hammonp spoke of the loss of aquatic insects and the
destruction of terrestrial habitat. Dragonflies had become much scarcer,
even common species such as Pyrrhosoma nymphula (Sulzer) suffering from
the slightest pollution. However, he noted that Ischnura elegans (Van der
Liden) was one of the few to be tolerant of mild pollution and as a con-
sequence it is now becoming widespread. He predicted that other insects
may adapt to pollution in time. On the Basingstoke Canal, Surrey, 40 years
ago there were 23 species of Dragonflies, today these are reduced to about
3 and the present drastic ‘improvement’ may see the loss of even these
The dipterous fauna of his home ground at Wood Green, North London
was illustrated in a series of slides. In the immediate post-war period two-
thirds of the insects pictured in his book ‘Flies of the British Isles’ were
taken within a few hundred yards of his home; today he would find only
one-sixth — a ratio of 4: 1. One of the worst events was spraying of stinging
nettles in Scout Park since the herbicide seeped into an excellent pond,

PROC. BRIT. ENT. NAT. HIST. Soc., 1979 53

and he had never since seen attractive aquatic species such as Oxycera
trilineata (Fab.), O. pulchella Mg., Odontomyia viridula (Fab.), Stratiomys
potamida (Mg.) and Sepedon sphegea (Fab.). Though the pond had
recovered, it was so isolated within an urban area that recolonisation by
these scarce flies seems unlikely. The ground surrounding the pond used to
contain 100 species of wildflowers, but spraying annd mowing has reduced the
flowers; and terrestrial diptera such as MXanthogramma _ pedissequum
(Harris), Coremacera tristis (Harris) and Physocephala rufipes (Fab.) are
no longer found. At Bookham Common, Surrey, he blamed cutting and
burning of sensitive areas as the reason for the loss of the rare parasitic flies
Alophora hemiptera (Fab.) and Gymnosoma rotundatum (L.). However,
he admitted some gains, even at Wood Green. A slide showed a press
cutting ‘Volucella zonaria (Poda) found in Wood Green’ and in 1960
readers used to headlines of murder, robber and rape would be relieved to
find it was a large harmless wasp-like hoverfly; it has bred ever since in
this area and become common in S.E. England. A related species which
also breeds in wasps’ nests V. inanis (L.) has established in the last ten
years. The dragonfly Aeshna mixta Latr. was a rare immigrant in Britain
until 40 years ago when it was first found breeding. It is now quite common
all around the London area.

The President, Mr. R. Tusss, felt that we should do more to encourage
those responsible for the management of commons. This led Mr. S. N.
Jacogs to comment on the declining value of Hayes Common, Kent, due
to bracken invasion; it was probably too late to anything now.

Mr. K. Evans reported the loss of the Chalk form of the Silver-studded
Blue, Plebejus argus (L.) form cretaceus Tutt, from east Surrey due to
land-use change.

The President asked if anyone had surveyed Beddington Sewage Farm,
Surrey in view of its apparent natural history value. Mr. K. Evans said
that only casual recording had been carried out by lepidopterists, but he
agreed the site ought to have an interesting fauna. Mr. A. M. Hutson
referred to the extensive collecting by the late L. Parmenter who found a
tich diperous fauna there in the 1950’s, but unfortunately the area is now
drastically changed annd the water meadows have gone.

Mr. N. Cooke spoke of the value of ivy on old brick walls since at times,
as when in flower, large numbers of insects congregate about this plant.
Dr. C. G. M. DE Worms spoke of his experience as L.N.H.S. recorder of
Lepidoptera for the past 25 years. He felt the picture was not black and
that the position was more positive than negative. Three-quarters of the
British macro-lepidoptera have been taken in the London area and the
list is increasing. The plentiful parks inside London were still good
sanctuaries. A moth trap run by Bushby at the Zoological Gardens had
produced remarkable results in the early 1950’s, as had Dr. Bradley’s survey
at Buckingham Palace where, for example, the occurrrence of buckthorn-
feeding Geometridae was unexpected. Inner London squares have been
producing much more in recent years, for instance south-coast species
such as the Varied Coronet, Hadena compta (D. & S.) (which feeds on
Sweet William) have arrived. In reference to outer London, he said that
there had been more Purple Emperor, Apatura iris (L.), at Bookham
Common in 1976 than ever before.

The Goat Moth, Cossus cossus (L.), received several comments as a
result of Dr. de Worms finishing by saying that it was once a common

54 PROC. BRIT. ENT. NAT. HIST. SOC., 1979

insect of outer London and that he suspected that infected trees had been
removed as a hygiene measure by local authorities. Mr. K. Evans said
he had never seen the Goat Moth in the London area (he has recently
completed a survey of east Surrey including suburbia). Mr. E. WiLp said
that he formerly found larvae at Mitcham and Croydon, but there has been
no sign of the species in the last 30 years. Mr. J. M. CHaLMeRS-Hunr had
never seen the species in the London area but he knew of a report of larvae
in a tree that was cut down in Regent’s Park in 1860 which, according to
J. R. Hind, “‘laid open a ‘grubbery’ of about sixty larvae, some two dozen
of which were handed over to me in a flower pot. The ensemble formed
quite a nosegay. The man who operated on the tree said he was almost
stifled when he first disturbed their privacy” (Entomologist’s Weekly
Intelligencer No. 236: 19-20 (1861).

Mr. B. K. West reported that in the early 1950’s Cossus was strongly
established by the A2 road at Bexley, Kent in Balsam Poplars. Infestation
was so heavy that the tops of the trees were completely dead above 30 ft.
and he had on one occasion found 100 larvae and an evening visit would
Teveal up to six moths. The trees were cut down by Kent County Council.
(A. Stusss found six larvae in an oak just east of Southall, Middlesex, in
1958. The tree was cut down the following year to make way for an
electricity sub-station. A golf course a mile away had live oaks which had
clearly been heavily infested in the past. He has never beeen able to find
an infested tree in the London area since).

Mr. CHALMERS-HuNT was able to give two examples of micro-moths
where the best chance of finding the species is in London. The Tineid,
Triaxomasia caprimulgella (Stainton) occurs in Hyde Park (breeding in
decaying wood) and Glyphipteryx linneella is found on lime bark in such
localities as St. James Park. He also knew of several species which were
spreading within the London environs from Kent in recent years, such as
the Least Carpet, Jdaea vulpinaria (H.-S.). Other species are spreading in
from the west. Mr. K. Evans remarked on the appearance at Croydon in
the last 5 years of the Black Rustic, Aporophyla nigra (Haworth). He
commented that whilst minor ecological changes must affect some species.
others just seemed to keep going regardless. Mr. G. Prior gave further
example of a moth which in his experience was easier to find in London
than outside. The Toadflax Paug, Eupithecia linariata D. & S.) and its host
plant were plentiful within N.W. London. Emphasis was placed on the
importance of abandoned railway lines, shunting areas and other waste
ground for insects in London. He spoke highly of the squalid areas in the
Boroughs of Harrow and Brent such as Neasden.

The clearwing moths of N.W. Kent provided a tale of woe. Mr. B.
K. West spoke of his experience of the mid 1950’s compared with the
present day. The Hornet Clearwing, Sesia apiformis (Clerk), used to be in
pollarded black poplar, but is gone. The Red-belted Clearwing, Conopia
myopaeformis (Borkh.), was on apple trees; the trees are still there but the
moth has gone — perhaps parasites are to blame. The Currant Clearwing,
Synanthedon salmachus (L.) seems now absent, despite searching. In some
unrelated moths, a similar loss has occurred, as with the Black Arches,
Lymantria monacha (L.), which used to occur at Bexley, and the Rosy
Marbled, Elaphria venustula (Hiibn.), has gone from Joyden’s Wood. Mr.
CHALMERS-HUNT provided some reassurance by saying that C. myopaeformis
probably still occurs at Wood Green, North London. Mr. WEstT also
mentioned that the Brown-tail, Euproctis chrysorrhoea (L.), is spreading.

PROC. BRIT. ENT. NAT. HIST. soc., 1979 a9

In the last 3-4 years it has crossed to the west of the Darenth River near
Dartford, Kent and is also now in the local parks at Barking, Essex. Dr.
Bradley commented after the meeting, that this species has started to turn
up at Buckingham Palace.

Industrial melanism attracted comment. Mr. A. A. ALLEN referred to
recent studies on Biston betularia in the Liverpool-Manchester area which
showed a small increase of the typical form following reduction of air pollu-
tion. Mr. West had noticed some increase in the typical form in London, but
in 1976 there were more melanics than usual which evened out the situation
to one of no change. In the late 1950’s the black form of the Pale Brindled
Beauty, Apocheima pilosaria (D. & S.) was abundant in Joyden’s Wood,
Kent, but this form has now been replaced by a dull dark form. After the
meeting Dr. Bradley mentioned that he too had found an increase in typical
B. betularia until 1976 when 95% were black at Buckingham Palace
(possibly a drought related effect).

Mr. E. Witp has collected in the Croydon area for 50 years and
currently lives at Selsdon. Several species had only appeared in the last
15 years, including the Pale Shining Brown, Polia bombycina (Hufn.),
which is currently on the increase; Entephria flavicincta (Hub.), which has
occurred over the last 6 years; Aporophyla nigra (Haw.) 2 and the Alder
Moth, Acronicta alni (L.), which is spreading into the suburbs. The Alder
Kitten, Harpyia bicuspis (Bork.), now occurs at Limpsfield and seems to be
moving into suburbia. The Heart and Club, Agrotis clavis (Hufn.), is
generally thought of as a coastal species but last year there were 500
recorded to light at Selsdon. Jdaea vulpinaria is moving up the Wandle
Valley,, presumably coming from Abbey Wood, Kent; and Ostrinia nubilalis
(Hubn.) is now common. The Garden Dart, Euxoa nigricans L., is an
example of a species occurring in gardens and allotments but rarely in the
countryside; last year it was plentiful and very variable. Among the declin-
ing species around Croydon are the Cerura vinula which is now less common
and Orgyia antqua of which very few are now seen. Mr. Chalmers-Hunt
however, stated that the last species is still abundant within central London,
probably being more common here than anywhere else in Britain.

The President commented on the loss of the Brayling, Hipparchia
semele (L.) from Wimbledon Common. In his experience Mitcham Common
was the best place in Britain for varieties of Small Copper, Lycaena
phlaeas (Fab.). The status of the Stag Beetle was taken up by several
people. Mr. Evans said that despite the millions of tons of concrete
dominating the redevelopment of Croydon, this insect occurs in profusion
and it seems quite happy in the now small gardens and odd corners. The
Opening speaker was prompted to cite the late A. E. Gardiner who con-
sidered it was quite happy burrowing through the subterranean parts of
fence posts. The fences of Croydon are apparently still standing! Mr.
Jacoss once found 13 young larvae in an oak post in his garden. After the
meeting, Mr. A. Wea spoke of fluctuating numbers in the still frequent
population at Chingford. He remembers a particular abundance in 1953
when he picked up 50 quite casually. In Epping Forest, only 3 miles awy,
it is doubtful whether there is a single authentic breeding record. According
to the local press the Chingford variety has the habit of hovering with a
glaring gaze and then pouncing on old ladies (recorded here for posterity,
should habits not change in the next 100 years).

The only other beetle to be mentioned was Graphoderus cinereus (L.),
which Professor Owen said had recently colonised Black Pond, Esher

56 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

Common, Surrey. Mr. B. Jackson has lived 200 ft. up at the top of a
tower block at Ilford and gave some interesting comment after the meeting
following the introductory remarks about modern building design. Though
the building was only 3 years old, the Marbled Beauty Cryphia domestica
(Hufn.), was abundant, with larvae regularly walking in through the
window. They were breeding in profusion on moss, an unusual foodplant.
An m.y. light trap run on the roof was very productive, with Hawk Moths
being common. The aculeate Hymenoptera were discussed by Mr. G. R.
Else. Though collectors were few, there had been a succession of specialists
in the London area such as Saunders, Shuckards, Smith, Enoch and more
recently Guichard and Yarrow. Early last century, localities such as
Highgate, Hammersmith and Battersa Fields, yielded interesting faunas but
even by the 1860’s Smih lamented the deterioration of Hampstead Health.
The latter locality lost 75 species by 1900 according to G. M. Spooner.
During the second world war whole colonies may have been destroyed by
digging for sand bags, but with some recompense that vertical sided sand
pits offered a new habitat for nesting. Another well documented site is
Bushy Park with over 140 species in a fauna which has seen both losses
and gains. One species, Ectemnius dives (L. & B.) was possibly imported
in timber and was first found in Britain in 1926 at Norwood; the species is
now spreading in Southern England, perhaps along railway lines.

It was of interest to note that the Wood Ant, Formica rufa L. was
recorded from Kensington Gardens in 1831 and from Hampstead Heath
in 1839 since it is now absent from within London. Professor OWEN
mentioned that is is still found on the Surrey outskirts at Oxshott.

Dr. B. MacNutty drew attention to the important feature of London
that its temperature is 3-4 degrees higher than the surrounding countryside
which he considered attracted the moths in. He was critical of the liberal
use of insecticide by gardeners and unlike some earlier speakers he con-
sidered that there used to many more green patches than there are today.
Professor Owen said that he had found 20 species of beetle in his garden
at Epsom which he had seen nowhere else. He continued that most people
keep a record of what they find in their garden and such data would be
of considerable historical value if only there was an archive where it could
be lodged. This was a cue for Mr. J. Hearn, who recalled that the Biolo-
gical Records Centre acts as an archive for all invertebrate data, regardless
of whether a special scheme is operating or not.

CONCLUSIONS

Some very interesting points (raised by eighteen members) came out of
the discussion. Many of the changes are due inevitably to the loss, altera-
tion or pollution of habitat. Acquatic life in particular has suffered. Some
other changes which have undefinable causes include losses such as the
Goat Moth or gains in species showing expansion in range. Such categories
of change are features paralleled in most parts of Britain and are by no
means specific to London. It is no easy matter to recognise types of change
which are unique to London. There are examples of insects which seem
easier to find in London and its suburbs than in the countryside, and
perhaps with more historical information we would have been able to
recognise a growing adaptation of insects to urban life.

The subject is certainly of interest to London entomologists and in the
year 2077 future members will be looking back to the record we have left
them. The suggestion of archiving records from our gardens is worth further
consideration by the Society, perhaps providing stimulus by promoting a

PROC. BRIT. ENT. NAT. HIST. soc., 1979 a7

garden search year at 10 year intervals —that really would provide an
historical record of immense interest to future generations of members. The
need for recording level of abundance or scarcity is very apparent. It is
hoped that the meeting will have made us aware of the sort of notes,
exhibits and communications which we might offer to our Society in order
to assist the record for the future.

PROCEEDINGS

Thursday 27th July 1978
The President, Mr. G. Prior, in the chair.

EXHIBITS

Dr. A. A. ALtLEN.—A specimen of Boloria euphrosyne (L.) (Lep.,
Nymphalidae) taken at Arundel, Sussex, on 31.v.1978, of which the left
hind-wing was one-third the usual size. Its flight had been unaffected and
only on capture was abnormality discovered. Also two @ of Limerodes
arctiventris (Boie) (Hym., Ichneumonidae) captured on 15.vii. 1978 at
Arundel, Sussex, while flying over low scrub-land inn the evening sun.
Apart from the uncommonness of the species and the fact that its host is
unknown, the exhibitor drew attention to the variable colouring of the
abdomen, entirely black in one of the males exhibited, but (the more
usual form) red-coloured in its apical part in the other. The exhibitor
thought that collecting lepidoptera pupae in grass stems in the above
locality might reveal which species was its host. He also showed some
colour photographs from a book entitled “Insects” recently published by
Time-Life in the Netherlands and particularly to the pictures illustrating
experiements by Dr. Williams of Harvard University in 1942 on Robin
moths, Hyalophora cecropia (L.) during metamorphosis.

Mr. G. Prior — Four larvae of Eupithecia lariciata (Freyer) (two from
Royston, two from Watlington) showing extremes of dimorphism (brown
and green forms).

MEMBERSHIP

Mr. G. M. Burton, his name having been read for the second time,

was duly declared elected a member.
COMMUNICATIONS

Mr. G. Prior reported that a couple of Eupithecia absinthiata (Clerck)
had remained in cop. for three days, whereas a few hours was normal in
this genus.

Mr. R. S. Tupss had found a concentration of Aphantopus hyperans
(L.) ab. arete in a wood near Winchester and had obtained ova from a
female of this form, which lacked white rings on its underside.

Slides were then shewn by Messrs. Agassiz, Ashby, Allen, Merrifield,
and Wiltshire. At the end the President said that it was regrettable such
an interesting lot had been shown to so small a house and suggested that
some of the slide-exhibitors might give a full-length talk on their photographs
and there would then be time for a full-length discussion of the topics
evoked. This was with reference to Mr. Ashby’s stimulating pictures of
experiments of letting moths settle on backgrounds of their own choosing.
which appeared relevant to the problem of procrypsis and how the

Thursday 14th September 1978
The President, Mr. G. Prior, in the chair.

The President announced with regret the deaths of three older members:
Messrs. C. Wainwright, a member since nearly fifty years; L. W. Siggs,
since thirty years; and R. C. R. Crewdson, since 1933; the last-named having
presided over the Lancashire and Cheshire Entomological Society, for
many years.

EXHIBITS

Dr. A. A. ALLEN—Living larvae and five females of Paracystola
acroxantha Meyr. (Lep., Oecophoridae) all captured at roof-top light at
Dawlish, Devon in late July or early August; a @ seen unfortunately
escaped. Sixty-six ova were obtained from the captured moths. About one-
third were put into cold storage, but the others hatched in mid-August.
Eucalyptus was offered as a pabulum and was readily accepted by the
newly hatched larvae, thus providing the first record of the species’ food-
plant. While still in Devon the exhibitor was able to continue to provide
this tree’s foliage. The larvae fed gregariously in groups of six to seven,
eating the outer surface of the leaf and living in the eaten depressions
which were spun over with grey silk. After their first meal the larvae
changed colour from whitish to pale greenish with a shining brown head.
They became very active if the leaf on which they fed was turned upright
but always returned to the feeding web. One or two larvae preferred to
eat at the base of a shoot of Eucalyptus but this was exceptional. Bay and
palm foliage were also offered but not eaten. However, on 13.vii a few
larvae were observed to be feeding at the edge of a leaf of a Berberis sp.;
this proved later to be a secondary foodplant, the first choice remaining
Eucalyptus. A few were now as large as 7 mm. in length and were more
solitary when exhibited. They sometimes ate withered Eucalyptus leaves
but preferred fresh ones. A few of the eggs from cold storage hatched and
the larvae fed slowly in the same manner. As the exhibitor had now
obtained nine specimens of this moth in three consecutive years he con-
sidered that this showed P. acroxantha to be established in the Dawlish
area. He acknowledged gratefully the assistance of the guest-house pro-
prietress in Dawlish, especially for the delivery, after his departure and
return to Reigate, of fresh foliage of Eucalyptus to him there.

Dr. ALLEN also exhibited a male Hoplismenus bidentatus Gmelin (Hym.,
Ichneumonidae) captured flying low over wild herbs on Hackhurst Downs,
Gomshall, Surrey, 16.vii.1978. The species, which has been recorded as a
parasite of Vanessid and Satyrid butterflies, appears to be rare. An
additional point of note was that the key from which it was determined
contains an apparent error: the hind tibiae of the male are stated as being
ivory, whereas the exhibited example and a few @ specimens in the
National collection (B.M.N.H.) all had entirely black tibiae, but all had
the 3rd and 4th segments of the hind tarsi ivory, together with all of the
2nd segment except for the extreme base; the extreme base of the 5th
tarsal segment was also ivory. Presumably one should read tarsi for tibiae
in the key.

H. N. E. Aston and A. J. Hatsteap — (i) Bruchidius dorsalis Fahr.
((Col., Bruchidae) (the Gleditschia seed-beetle); these began emerging in
April from seed pods collected in Rome, Italy, December last year. The
host plant is a Gleditschia sp., probably the honey locust, G. triacanthos,

PROC. BRIT. ENT. NAT. HIST. Soc., 1979 59

which is a N. American tree grown in Europe for ornamental purposes.
This and other Gleditschia spp. are grown in Britain but they rarely set
seed here, so this bruchid beetle is unlikely to be found here, except in
imported seed. The beetles have bred and produced a second generation in
the dry seeds. Attempts at rearing them on pea, broad beans and french
bean seeds were unsuccessful. (ii) Knopper gall on oak, cause by Andricus
quercus-calicis Burgsd. (Hym., Cynipidae), a comparatively recent addition
to the range of cynipid gall-wasps attacking oak (Quercus robur) in this
country. It has occurred in the Channel Isles for many years but was not
recorded on the British mainland until 1961 when it was found in
Northamptonshire. It remained scarce at first but after 1970 began to spread
and has now become quite common in parts of Surrey and is also recorded
from Devon, Somerset, Wilts., Warwick, Leics., Beds., Norfolk, Essex,
Glos., Hants., Herts., Lincs., and Suffolk. Eggs are laid in the developing
acorns which become converted into thick-walled, domed structures. Each
gall contains a single, thin-walled, larval chamber. When galls first appear
in August, they are yellowish green and sticky; later they become dry, brown
and woody. The galls fall to the ground in the autumn and the larva pupates
inside the gall. On the Continent, females emerge in the spring and lay
egss on the catkins of Turkey oak, Quercus cerris. These catkin-galls give
rise to both males and females which, after mating, produce the acorn
knopper galls. Many oak cynipid wasps have a life cycle that involves an
alteration between sexual and asexual generations causing different types of
gall. and in some of these species the sexual generation is not obligatory.

Lt. Col. A. M. EMmMer — Caloptilia rufipennella (Hiibn.), new to Scotland,
four adults reared 16-19.viii.1978 from larvae taken on 19.vii.78 in
Yair Hill forest, Selkirkshire. Larval cones were also observed on
sycamore (Acer pseudoplatanus) in Northumberland (VC68); Dumfriesshire
(VC72): Peebleshire (VC78); and Berwickshire (VC81). The species has
hitherto been recorded only from Essex, Cambridgeshire, Norfolk, Suffolk,
and Lincolnshire. Also larval mine and folded leaves of alder (Alnus
glutinosus) taken beside Loch Lomond in Dumbartonshire. These
apparently show the feeding of Caloptilia falconipennella (Hibn.), a species
not recorded from Scotland. The map reference of the locality is 27/3203.
Maps were also shewn of the distribution of both moths in the British
Isles.

I. Sims — A variety of Acasis viretata (Hibn.) (Lep., Geometridae) taken
at Rothamsted Light-trap site no. 305, Chigwell Row, Essex, on 8.viii.1978,
also a more typical example, taken in the same trap on 30.vii.1978, for
comparison.

P. A. SoKOLOoFF — examples of the dusky thorn (Ennomos fuscantaria
(Haw.)) from Orpington, Kent, including an aberration in which the two
cross-lines of the fore-wing are missing.

MEMBERSHIP
The obligation book was signed by Mr. A. J. Halstead.

COMMUNICATIONS
R. S. BRETHERTON reported that migrants were few this year in both
Surrey and Devon. Other members also reported rather similarly.

J. M. CuatmMers-Hunt reported that a reliable observer had seen one
example of Nymphalis antiopa (L.) in Kent; he and Dr. ALLEN reported that
Argynnis paphia (L.) was flying as late as September (Breconshire and
Haselmere respectively); but Dr. I. WATKINSON reported that he had seen
one example of a second brood of Diaphora mendica (Clerck) in Kent, an
exceptional occurrence.

Dr. A. A. ALLEN then gave an illustrated talk on “An outline of the
biology of the Ichneumonoidea, with particular reference to those para-
siting Lepidoptera’. This began by mentioning the two familes composing
the superfamily and the venational and abdominal characters thereof.
Various aspects of the biology were expounded, and the lecturer ended by
appealing to lepidopterists to retain their bred parasites.

28th September 1978
The Vice-President, The Rev. D. J. L. Agassiz in the chair.
EXHIBITS

Dr. A. A. ALLEN—Two @ examples of Syzeuctus maculatorius (F.)
(Hym., Ichneumonidae) swept from heather on moorland near Dawlish,
Devon, 5.viii.1978. A third @ was similarly obtained 11.viii.78. The species
appears to be rare, nearly all the records coming from heaths around
Swanage, Dorset. The only host from which it has been recorded is
Oncocera genistella Dup. (Lep., Pyralidae). The species is most distinctive
with black and bright yellow contrasting colours and apically infumated
wings.

J. M. Cuatmers-Hunt — A larva taken at Dungeness on 19th September
which other members identified as an immature Lasiocampa quercus (L.)
(Lepidoptera).

Lt. Col. A. M. Emmet — Larval feeding believed to be that of Epinotia
fraternana (Haworth) on Abies grandis collected at Chalkney Wood, Earls
Colne, Essex, 26.ix.1978.

C. O. HammMonp—A _ specimen of Strangalia aurulenta (F.) (Col.,
Cerambycidae) from Stover Lake, Bovey Tracey, Devon; collected on
21.vili.78, this striking beetle was flying in circles above birch-logs which
had been put down over a marshy spot at the end of the lake.

The following, their names having been read for a second time, were
duly declared elected as members:— Miss L. Vigne, and Messrs. J. J.

Taylor, S. F. Taylor, F. R. Pratt, M. D. Laux and K. D. Z. Samuels. The
obligation book was signed by Messrs. P. Jewess and M. R. Brown.
ANNOUNCEMENTS
Mr. J. Heatu said that the European Lepidopterists’ Society, of which
he himself was the British branch secretary, had now attained a member-
ship of 500 members but that the British membership was still dispropor-
tionately low. He therefore left some leaflets about it in the hope more
would join.
COMMUNICATIONS
C. G. M. DE Worms said that the late summer and early autumn had
been good, and he himself had spent five or six days on Guernsey where
the commonest butterfly seemed to be the speckled wood (Pararge aegeria
(L.)) and the moths Agrotis trux (Hiibn.) and Eilema caniola (Hiibner)
had been very prevalent; he had also noted a pale form of Lasiocampa
trifolii (D. & §.), Leucochlaena oditis (Hiibn.), Mythimna_ putrescens
(Hubn.) and Scotopteryx peribolata (Hiibn.), the last-named not being
known from other parts of the British Isles.

PROC. BRIT. ENT. NAT. HIST. soc., 1979 61

K. Evans stated that Aporophyla nigra (Haworth), never noted near
Croydon before 1969 and previously scarce in S.E. England, seemed now
well established there, and he had noted forty specimens in his trap there
in the last ten days. Mr. E. Wilde agreed and added that Polymixis
flavicincta (D. & S.) had also become commoner recently at Croydon. I.
WATKINSON stated that in N. Kent Rhyacia simulans (Hufn.), not hitherto
authentically recorded there, a male was caught on 28.ix.78 at Boughton,
and Eumichtis lichenea (Hiibn.) was now (both) established and common.
He asked members who might obtain apple-feeding examples of Phyll-
onorycter cydoniella (D. & S.) (Gracillariidae) kindly to submit specimens
to him, since this species was originally thought to be specific to quince
(Cydonia) and was often confused with P. blancadella (F.). R. F.
BRETHERTON said that R. simulans was not a regular immigrant and there
had been previous scattered records of it in Surrey. Mr. G. ELSE reported
a dearth of the regular immigrants at Freshwater, I1.0.W. about 28.vili
although an example of Agrius convolvuli (L.) had been taken, and a
few Colias crocea.

M. W. F. Tweepie then gave an illustrated lecture on “Insects in
Australasia 1977” which justified the large afflux of members to hear
him and see his latest photographs. These, as usual, covered different
orders of insect and also plants and trees. Apart from appreciating the
high quality of these and the clear exposition of the speaker, members
showed their interest in the phenomena illustrated by posing various
questions at the end.

COMMENTS ON THE EXHIBITS

It was mentioned that Srrangalia aurulenta had been recorded by Huggins
from S. Ireland about 1950; another record, in 1965, was from Arundel
Park.

12th October 1978
The President, Mr. G. Prior, in the chair.

The President announced with regret the deaths of the following
members: — Brigadier H. L. Lewis, author of “Butterflies of the World’,
and J. Welton, aged 24.

EXHIBITS

Dr. A. A. ALLEN—A male specimen of Telciodes alburnella (Z.) (Lep.,
Gelechiidae) captured to actinic light at Reigate, Surrey, 28.vii.1978; the
larva feeds on birch. It is apparently moving southwards in Britain. Also
a couple of Netelia testaceus Gravenhorst (Hym., Ichneumonidae), the 92
captured flying in late afternoon sunlight on Seaford cliffs, Sussex, 4.ix,
and the @ take to m.v. light on 11.vili, at Holocombe, Devon, both this
summer, the ¢ being larger. The genus comprises ectoparasites mainly of
the Lepidoptera; the fertilised black eggs of the female are carried on the
outside of the ovipositor until a suitable host is found. Thirdly two females
of Platylabus decipiens Wesm. (Hym., Ichneumonidae), bred 10.vi.1978
from two pupae of Perconia strigillaria (Hibner) (Lep., Geometridae),
found as larvae by Mr. C. Hart on 30.iv.78 on Horsell Common, Woking,
Surrey. The larvae pupated soon after capture. The species is apparently
a rare insect; the exhibitor had found no literary record of its having
previously been found on this moth.

Lt. Col. A. M. Emmet — Specimens of Cosmiotes consortella (Stainton)
(Lep., Elachistidae) taken at various dates in Essex from 1966 to 1978,
also two taken at Balyconneely, West Galway on 4.vi.68 and 23.viii.69;

62 PROC. BRIT. ENT. NAT. HIST. soc., 1979

and a specimen bred by Mr. J. L. Gregory at St. Austell, Cornwall on
l.iv.1971. Specimens of C. freyerella (Hibner) and stabilella (Frey) were
shown for comparsion. C. consortella was regarded as conspecific with C.
freyerella by Meyrick; consequently it was overlooked for many years. It
was restored to the British list in 1951 by Dr. J. D. Bradley under the
name C. exiguella (Frey), a name since shewn to be a junior synonym of
consortella. A map was shown showing the distribution of the records
made before and after G. consortella was regarded as conspecic with
C. freyerella; it was suggested that the discontinuity was due to under-
recording rather than the absence of the species. The life history was un-
known, the single bred specimen having emerged fortuitously in a cage
which was being used to rear Noctuid larvae on grass.

G. Prior —three immature larvae feeding on tomato foliage, which
some members thought were Lacanobia oleracea (L.).

Dr. I. WATKINSON — photo-micrographs of larval tubercles and spiracles
of noctuid larvae of the Heliothidinae, up to magnifications of 60,000,
some being of taxonomic importance for distinguishing one species from
another; also, of a hatched ovum of Phyllonorycter sp. electroscanned

COMMUNICATIONS

Dr. I. WaTKINSON reported Lithophane leautieri hesperica Boursin from
Canterbury, E. Kent, in early October. Various members reported a few
late immigrant lepidoptera due to the improved weather, and Dr. ALLEN
reported having found a larva of Acronicta rumicis (L.) feeding on
Cupressus.

Slides were then shewn by four members; R. K. Merrifield shewed
landscape scenes using infra-red and normal colour film; Dr. Ian Watkinson,
shewed the damage done to apple blossom by Argyresthia cornella (F.);
Mrs. Murphy of spiders and habitats in the United States; and Dr. Allen,
mostly of Lepidoptera larvae.

COMMENTS ON EXHIBITS

Lt. Col. A. M. Emmet said that 7. alburnella had been found fairly
widespread in Essex, whence he knew it from Snaresbrook; however, a
description of its spinnings was still required.

9th November 1978
The President Mr. G. Prior in the chair.
EXHIBITS

Dr. A. A. ALLEN — two examples of Barylypa insidiator Foerster (Hym.,
Ichneumonidae), captured flying low over heather in afternoon sunshine,
Hankley Common, Tilford, Surrey, 30.viii.1978. Two other species of the
genus are known from Britain; all three are very rare, possibly overlooked.
Many species of the sub-family, Anomalinae, to which they belong, show
a preference for dry heaths and moors. Also a few examples of both sexes
of Microgaster subcompletus Nees (Hym., Braconidae) bred from a full-
grown larva of Vanessa atalanta (L.) (Lep., Nymphalidae) swept from
nettle (Urtica) on 2.ix.1978 on the coast at Littlehampton, Sussex. The
gregarious parasites appeared from the host the following day and pro-
ceeded to spin their rather large white, woolly cocoons. The adults emerged
therefrom on 16.ix. The species is a notorious parasite of atalanta (as well
as of Pleuroptya ruralis (Scop.) (Lep., Pyralidae) and may be responsible
for the scarcity of the Red Admiral Butterfly in some years.

COMMUNICATIONS

Dr. A. A. ALLEN said that he had obtained eggs from the moths hatching
from Paracystola acroxantha Meyrick bred ex ovis obtained in Devon
recently, and would bring them next meeting for distribution.

Messrs. E. WiLp and R. BRETHERTON both reported that a second wave
of immigrant lepidoptera had arrived in Southern England, as evidenced
by the appearance of Orthonama obstipata (F.) in Surrey light-traps; there
were also reports of Mythimna unipuncta (Haw.) on the South Coast dur-
ing the last ten days, but whereas the October 7-15 migration appeared to
have come from the south-east, this second, rather small, migration,
seemed, to judge by wind records, to be from the south-west.

Dr. WATKINSON reported that he had had Udea ferrugalis (Hibn.) and
M. unipuncta to his light-trap near Canterbury, Kent, on November 3-6.

Mr. G. Prior reported that Emmelina monodactyla (L.) had been
numerous on fences and shop windows in N. London suburbs recently.

Members also discussed cannibalism in lepidopterous larvae.

A discussion on the Annual Dinner and Exhibition then ensued. The
President expressed appreciation of the work done by the ladies in providing
refreshments and stated that a reservation at Chelsea Town Hall for
October 27th next year for the Exhibition had been made, a week later
being impossible.

Dr. A. A. ALLEN then exhibited, and spoke about, some slides showing
the life-cycle of Paracystola croxantha Meyr. and certain cannibal larvae in
action, and winter and spring months at rest.

The President having expressed the audience’s appreciation of these,
the meeting came to a conclusion somewhat sooner than the usual hour.

EXHIBITS

Dr. A. A. ALLEN — A single female of Apanteles callunae Nixon (Hym.,
Braconidae), bred 9.vii.1978 from an unidentifiable species of Geometrid on
heather, 30.vii.1978, on moors near Dawlish, Devon. The larva was killed
l.vili, the parasite maggot constructing a pale-lemon cocoon, also exhibited,
attached by its base, on a spray of heather. The species callunae does not
appear to be recorded very frequently, possibly being overlooked. All
previous records have been found from moorland or heath and it is
perhaps likely that the species is to be found in this locality only. The
only known host published, known to the exhibitor, was the Noctuid A narta
myrtilli (L.). Also larvae and bred adults of Paracystola acroxantha Meyr.
(Lep., Oecophoridae).

R. BRETHERTON reported that the autumnal immigration had continued
through mid-November, the chief species concerned being Mythimna
unipuncta (Haw.) which was extremely numerous on the south coast of
England and the west coast of Ireland, far outnumbering such species as
Nomophila noctuella (D. & S.) and Autographa gamma (L.); only one
Hippotion celerio (L.) had been noted. The immigrants had hardly pent-
trated inland. Confirmation for Essex of this state of affairs was offered
by Lt. Col. A. M. Emmet, who stated that at Bradwell-on Sea on the
coast of that county M. unipuncta had been five times as numerous as
A. gamma. The observer being Mr. A. J. DEwIck.

Dr. I. WILKINSON reported that forty-five members had attended at a
meeting of the Kent entomologists near Faversham; the next such meeting
would be on April 6th 1979.

Dr. J. Mason then gave an illustrated talk on “Insect photography in
the tropics’. Among the creatures shewn on the screen were: ants, butter-
flies, spiders, millipedes, land-crabs, fiddler crabs, and bats of Trinidad,
Africa, Malaysia, Ceylon, and India. The lecture drew a large audience of
interested members and evoked much interest.

COMMENTS ON EXHIBITS

Lt. Col. A. M. Emmet, congratulating Dr. Allen on his work on Para-
cystola acroxantha Meyrick, stated that Dr. Bradley had decided, on the
basis of this work, to remove the asterisk against the species in the British
check list, being satisfied that the moth was a breeding resident in Britain.

Wednesday December 6th 1978

JOINT MEETING WITH THE ROYAL ENTOMOLOGICAL SOCIETY
The President of the R.E.S., Prof. J. D. GILLetr, in the chair.

The first joint meeting took place at 41 Queens Gate; there was a full
house, with some obliged to stand; congestion might have been intolerable
had a one-day railway strike affecting residents in Surrey not reduced the
numbers somewhat.

The President succinctly conducted business which concerned the host
society and then welcomed visitors to the meeting especially those from our
society and from Europe; the theme for the more serious part of the even-
ing being: “The European Insect Fauna in relation to Britain’, he hinted
that we might be dealing with a sort of ““Common Market for Insects’’.

RELATIONS OF THE RESIDENT BRITISH LEPIDOPTERA TO THE
EUROPEAN FAUNA

Mr. E. P. WILTSHIRE then spoke for about a quarter of an hour on the
above theme, with special regard to the resident Lepidoptera. He draw
attention to Mr. R. S. Bretherton’s 1968 Presidential Address (see these
Proceedings Vol. 1 (1): 4-15), and quoted the comparative numbers there
given for the species in the butterfly faunas of Britain and its neighbours.
It was natural that on the extreme N.W. edge of Eurasia, the species-number
should decrease toward the west and north, particularly in island faunas:
the further from the warm latitudes and the centres of dispersal, the more
pronounced the decrease, and this impoverishment was enhanced by a
sea-barrier responsible for non-arrival or extinction after arrival of species.

Maps prepared by Mr. J. Heath were used to illustrate ranges of ten
species of butterfly or moth representing seven faunal elements; the latter
were groups of species with roughly corresponding present distributions:
naturally each species had its own ecological peculiarity and its own distri-

PROC. BRIT. ENT. NAT. HIST. soc., 1979 65

bution differing in detail from that of every other; some were expanding
and on the up-grade, while others were stationary, localised, or declining;
the expanding ones perhaps indicate the future and the declining ones the
past.

Three elements together formed the great majority of the British
lepidopterous fauna: Euro-Pacific, Euro-Siberian, and Euroriental (West
Palearctic). Four other elements formed a smaller fraction of our
fauna and of these only one or two were truly European; Lusitanian
(Atlanto-Mediterranean), Holarctic, Boreo-Alpine, (Arctic-Alpine), and
European; the last contained perhaps the most enigmatic distributions of all.

The two species chosen to represent the Euro-Pacific range were Inachis
io (L.) (peacock butterfly) and Photedes elymi (Tr.) (limegrass moth) con-
trasted strongly for the former was almost ubiquitous, the latter limited
mainly to one species of grass on Northern coasts.

Melitaea cinxia (L.) (Glanville fritillary butterfly) was the Euro-Siberian
representative, in Britain severely localised to off-shore islands of the
extreme south, and limited also to high peaks towards its own southern
limits (e.g. the Middle East) but widely distributed over a vast central band
extending from Western Europe to the Amur at least. For the Euro-
orientals, Quercusia quercus (L.) (purple hairstreak butterfly), and Yestia
xanthographa (D. & S.) square-spot rustic moth) were another contrasting
pair of representatives, the former generic to oak trees from Britain to
S.W. Iran and the latter, a herbivore, more ubiquitous over a very similar
territory.

The selected Lusitanian representative was the purely coastal moth
Mythimna litoralis (Curtis) (shore wainscot), localised and specific to one
kind of dune-grass from N. Germany, through Britain to N.W. Africa and
S. France. Mentioned en passant as in the same category was Lithophane
léautieri Boisd. (Blair’s Shoulder-knot), whose recent arrival and continued
expansion in the British Isles was the result of recent plantations in N.W.
France and S. England of Cupressus macrocarpa (Westw.) the Monterey
Cypress.

The Holarctic representative, Itame brunneata (Thunb.) (Rannoch
looper) inhabited the Scottish highlands, the European Alps and also a
broad band in the northern latitudes of the Old and New Worlds. The
Boreo-Alpine representative was another Scottish highland specialist XYestia
alpicola (Zett.) (northern dart), but was more widespread in Scandinavia
and also inhabited the Alps.

Finally the selected representatives of the purely European category were
another constrasting pair: Erebia epiphron Knock (mountain ringlet butter-
fly) which had disjunct habitats and ranged from the north of Britain to the
Pyrenees and the Alps, but was absent from Scandinavia; and Photedes
morrisii (Dale) (Bond’s wainscot moth) severely localised on Northern coasts,
specific to a single kind of grass which, surprisingly, was not purely coastal
but widespread, the moth being also found in East Central Europe, the
Appenines and reportedly also the Balkan mountains.

Questions and contributions from the audience then followed; Dr. G. R.
Coope’s contribution was noteworthy, concerning the Coleoptera which
he has been studying. Glacial British Coleoptera, he said, were perfectly
preserved and could be exactly determined and dated; the results were
unexpected, e.g. a glacial British beetle species now survived no nearer
than Tibet. In his view, deductions from present distributions could often
be misleading. Mr. J. Heath, referring to the butterfly statistics cited from
Bretherton 1968, mentioned that Iceland had no Rhopalocera.

The chair then waved a wand transforming the meeting into a con
versazione at which mulled wine circulated. This proved thoroughly enjoy-
able to all, but provided no matter for record here, except that a brief
mention of the various exhibits on the theme should be made: these
related to other groups of insects, e.g. the Colorado beetle, the Curuculioni-
dae and the aphids, whose ranges of expansions and retreats were well
displayed.

Thursday December 14th 1978
The President, Mr. G. Prior, in the chair.
The President regretted to announce the death of Sir Henry B. Lawson,
of Pirbright, Surrey, a member since 1927.

EXHIBITS

Dr. A. A. ALLEN — Three females and one male of Apanteles calodetta
Nixon (Hym., Braconidae) four of a brood of twelve bred from larva of
Eriogaster lanestris (L.) (Lep., Lasiocampidae). About twelve quite young
host larvae were found in a web on birch (Betula) in Sweden on 17.vi.1977
by Mr. C. B. Ashby. The larvae developed normally until nearly mature,
when several Apanteles larvae appeared from nearly every host, proceeding
to spin their small, yellowish buff cocoons amongst the larval hairs. The
twelve cocoons of the exhibited brood were given to the exhibitors on
13.x and were kept over-winter indoors; some eventually hatched in mid-
summer 1978. Only five adults appeared; on opening two intact cocoons
the exhibitors found a dead larva in each. The species is very infrequent,
having been first described by Dr. Nixon in 1973 from a series bred in
Mid-Sweden from the same host; the present series contained the first
known male example. The exhibitor expressed his thanks to Mr. Ashby for
the gift of the cocoons, which he so thoughtfully retained.

R. FarrcLouGH — Five examples of Teleiodes decorella (Haworth) (=
humeralis (Zeller) (Lep., Gelechiidae), two being so melanic that the black
mark on the costa was indistinguishable. The local moth is to be found in
Surrey but is rather uncommon.

T. G. Howartu (on behalf of V. W. Puitpotr) —a living specimen of
Mythimna unipuncta (Haworth), the White-speck Wainscot moth (Lep.,
Noctuidae) taken at his m.v. light on the night of December 9/10, also
living larvae of the same species, in various instars, bred from a female
taken on November 10/11 at Waymouth, Dorset. Mr. Philpott reported
having seen 37 specimens of unipuncta since November 2/3, and twenty-
five on the night of November 10/11. During recent years he has seen the
moth regularly though in fewer numbers than this year and believes it may
have established itself at Weymouth.

S. A. KNiLL-JoNEs — larvae of Mythimna unipuncta bred from several
females obtained at m.y. light at Freshwater, I.0.W. on November 11th,
when a total of ten specimens of this moth were taken.

MATTERS ARISING FROM THE MINUTES

It was announced that Mr. Fairclough, in response to a recent request,
had donated a vacuum cleaner for use in the library. The President
invited volunteers to operate it.

ANNOUNCEMENTS

The President said that the Joint Meeting with the Royal Entomological
Society on December 6th had been a great success and he had received
suggestion that it might well be made an annual event.

COMMUNICATIONS

R. F. BRETHERTON cOmmenting on the dates of capture of Mythimna
unipuncta as reported above, pointed out that a frost had occurred between
the two periods of capture, which suggested that if this had killed off the
first arrivals, the second lot must be a second immigration. Arrivals in
S.W. Ireland were even more numerous than in S. England, 114 examples
having been found in one night in a single trap at Cork. There was no
proof of the moth having survived an English winter in the wild, and he
hoped members with larvae would experiment by exposing some of these
to wild out-door conditions on the south-west coast to see if survival there
was climatically possible.

S. Baker stated that although greatest numbers were along the coasts a
few specimens had also been recorded inland, e.g. one example at Reading
on 8th November.

Other members mentioned records of migrant butterflies having been
observed in the south-west of England, incluring Cynthia cardui (L.)
(painted lady) on December 4th in S. Devon and A. S. WHEELER mentioned
a late viewing of V. atalanta (L.) at Pagham Harbour, Selsey, Sussex, but,
as R. F. BRETHERTON said, migrant butterflies were scare this autumn, as
compared with migrant moths.

Mr. A. KENNARD then gave an illustrated talk on “The Large Blue —
lessons and achievements in insect conservation’, dealing mainly with the
history of Maculinea arion (L.) in S.W. England in recent years. A lively
discussion, lasting some thirty minutes, followed this, proving the great
interest evoked by the lecturer.

FIELD MEETINGS

RANMORE, SURREY — May 27th 1978
Leader — M. GREY

Nine members attended the meeting, the intention being to compare
conditions in the surrounding woodlands with the adjacent chalk downland
slopes. Leaving the leader’s house, the party had an enjoyable but unpro-
ductive walk through the woods. A female Aethalura punctulata (D & S.)
was found at rest on a tree trunk and kept by one of the party for eggs.
After returning to the house for tea and other forms of refeshment the
leader took the party to an area of chalk downland owned by the Wotton
Estate. Permission had kindly been given by Mr. John Evelyne for the
party to collect on this area during the afternoon and night — the rest of
the downland being owned by the National Trust.

Although the lateness of the season was generally apparent ten species of
Rhopalocera were recorded including H. lucina (L.) which, despite an
abundance of foodplant, has become scarce in the area. Mr. Paul Sokoloff
supplied a list of the ‘micros’ as follows: — ‘‘Pancalia leuwenhockella (L.)
was common on the downs, flying in the bright sunshine together with
beautifully fresh first-brood specimens of the Pyrausta species aurata (Scop.),

68 PROC. BRIT. ENT. NAT. HIST. SOC., 1979

purpuralis (L.), and nigrata (Scop.). Tortricids flushed from the herbage
were generally the common species such as Syndemis musculana (Hubn.),
Cydia juniella (Clerick) and Pammene rhediella (Clerck), although it was
interesting to see singletons of Cochylis atricapitana (Stephens) and a late
Acleris cristana (D. & S.). At dusk Elachista biatomella (Stainton) was
present in considerable numbers, by far the dominant member of the
Elachista group, there being only a few specimens of E. argentella (Clerck),
Biselachista cinereopunctella (Haworth) and Stephensia brunnichella (L.)’.

Three members stayed on to run lights during the night and total forty-
five species of ‘macros’ were recorded. Of particular interest were Agrotis
cinerea (D. & S.), which were very fresh, including one which was apparently
an asymmetric intersex variety, Nola confusalis (H.-S.) and an early Sphinx
ligustri L.

Numbers were noticeably down on average for the time of year due to
the general lateness of the season.

During the afternoon on the downs a large, long tailed bright emerald
green bird was seen by several of the members flying into some trees. This
caused some concern regarding the strength of the leader’s refreshment.
However, it proved to be a ring-necked parakeet Psittacula krameri, many
of which have escaped from captivity and are apparently breeding in the
wild in several of the southern counties.

HAYLING ISLAND, HANTS. — 3rd June 1978
Leader — A. J. PICKLES

Illness prevented the scheduled joint leaders, Mr. W. Collinson and Mr.
R. W. Watson from attending but good luck and helpful advice from the
Secretary made up for the leader’s lack of detailed knowledge of the area.

Six members and a further three members of their families assembled in

the car park adjacent to the Synah Golf Club at 6 p.m. and spent the
first two hours searching the shore area in front of the golf links, largely
for micros but also for the larvae of Lasiocampa trifolii (D. & S.), one
of the objectives of the meeting. This species was found commonly on both
Tree Lupin which abounds here, and grass growing amongst the Tree
Lupins. A large number of Polyommatus icarus (Rott) were noted at rest
on grass stems, often as many as three to a stem. Other butterflies noted at
the same time were: Lycaena phloeas (Linn.) and Coenonympha pamphilus
(Linn.). Aspitates ochrearia (Rossi) was also commonly put up, and was
later to be found at the traps. Amongst the micros found in this area, and
so far identified were: six larvae of Psyche casta (Pallas) on posts at the
entrance to the car park, and imagines of Plutella xylostella (Linn.) and
Eudonia angustea (Cutt.).
,As dusk was falling the party moved to the far end of the golf course
where permission had been obtained to park cars within the golf course only
a short distance from the sand dunes. A few larval webs of Malacosoma
neustria (Linn.) greeted us by the gate. A mixture of nine m.v. and actinic
traps were run along the edges of the dunes, two traps for unfortunately
short time due to mechanical failure.

Members also successfully searched the marram grass on the beach for
larvae of Mythimna litoralis (Curt.), examples of Agrotis ripae (Hiibn.)
being found at the same time expanding their wings. The fourth objective
of the meeting, Sideridis albicolon (Hiibn.), turned up at the lights fairly
late.

Among species recorded at the lights and not seen earlier wer: Aethes
smeathmanniana (Fab.), Pyla fusca (Haw.), Epirrhoe galiata (D. & S.),

PROC. BRIT. ENT. NAT. HIST. soc., 1979 69

Perizoma albulata (D. & S.), Lobophora halterata (Hufn.), Menophora
abruptaria (Thumb.), Serraca punctinalis (Scop.), Macrothylacia rub
(Linn.), Deilephila porcellus (Linn.), Arctia villica (Linn.), (nearly all of
which exhibited elongated cream markings at the base of the forewings as
compared with the typical), Diaphora mendica (Clerk.), Ceramica pisi
(Linn.), Acronicta megacephala (D. & S.) and Autographa gamma (Linn.).
The meeting ended at about 2.30 a.m. The automatic sprinklers which
started watering the greens and their surroundings added some last minute
excitement as they drenched some of the members who were staggering
across the golf course under the weight of generators and equipment.

SWANAGE — June 10/11th 1978
Leader — Mr. P. J. BAKER

Six members arrived for this meeting to be met with weather which
followed the pattern of that for several previous meetings at this venue —
cool and dull with a persistent N.W. wind.

Following previous reports, a number of stands of figwort on the edges
of the car park were examined and large numbers of larvae of Cucullia
verbasci (L.) were found. Some were only 10 mm. long but others were in
their penultimate instar. Checking other reports of extensive defoliation by
“tent caterpillars’? the tenanted webs of Ypsolopha spp. were found to be
common on blackthorn, as were numerous but isolated larvae of Mala-
cosoma neustria (L.).

The weather restricted flight activity but never-the-less several Polyom-
matus icarus (Rott), Erynnis tages (L.), and Ochlodes venata (B. & G.)
were noted and Electrophaes corylata (Thun.) and Camptogramma bilineata
(L.) were flushed. The most remarkable record was possibly that made by a
member who spotted a pupa of Strymonidia w-album (Knock) attached
to the underside of a branch of wych elm— which species of tree still
appears to be quite healthy in the area.

Working the holm oak, hawthorn and blackthorn showed that larvae
were somewhat backward with usual spring species on these pabula still
being much in evidence. Some stands of wild rose produced large numbers
of larva of Anticlea badiata (D. & S.) whilst the majority of these plants
were completely devoid of insects. Extensive growths of the sea pink along
the cliff edge were checked and signs of Bembecia muscaeformis (Esp.)
were possibly found though no stages of this insect were seen. Whilst
checking the sea pink, fine specimens of the bee orchid were seen, and
further plants were found later, scattered in suitable locations further in-
land. Another plant which was common over large areas was the kidney-
vetch but its associated butterfly was not seen.

A striking feature of this meeting was the large number of sea birds seen
—many of which had nests in various parts of the cliffs. The guillemot
was much in evidence and one small ledge at near sea level was densely
populated by these birds which reminded one of miniature penguins. They
were constantly in motion, flying low over the water or joining small flocks
of similar birds on the surface. As the sea was clear it was easy to watch
their submarine activities as they covered quite considerable distances
under water and stayed submerged for quite extensive periods. Also noted
were large numbers of several species of gulls, kittewakes, doves, cor-
morants, jackdaws and —- almost certainly —a pair of puffins. On the grassy
slopes inland several pairs of redstarts were noted.

One of the party found an unusual Homopteron near the cliff edge.

70 PROC. BRIT. ENT. NAT. HIST. SOC., 1979

This was subsequently identified by another member as Centrotus cornutus
(L.) which is said to be rare in Britain. This insect is most remarkable in
its appearance as it mimics a thorn.

At dusk the cloud cleared and there was a sharp temperature drop which
discouraged most of those present from running lights. However, a couple
of the more intrepid set up in a sheltered spot on the lighthouse road and
were able to add a few records to the list: Mada nana (Hufn.),
Mythimna pallens (L.), Apamea sordens (Hufn.), Procus spp., Agrotis
cinerea (D. & S.), Charanyca trigrammica (Hufn.), Lacanobia w-latinum
(Hufn.), Agrotis exclamationis (L.), Opisthograptis luteolata (L.), Dasy-
chira pudibunda (L.), Spilosoma lutea (Hufn.), S. lubricipeda (L.), Eupi-
thecia exiguata (Hubn.), Phlogophora meticulosa (L.), Hoplodrina ambigua
(D. & S.), Phalera bucephala (L.), Sphinx ligustri (L.), A'spitates ochrearia
(Ross.), Apamea monoglypha (Hufn.)

ANDREWS AND MEANFIELD WOODS, SOREHAM, KENT —

25th June 1978
Leaders —— P. SOKOLOFF and M. CHALMERS-HUNT

A dozen people attended this meeting which was held in a locality
threatened with building a motor-way. Despite a poor weather-report, the
party enjoyed a fair amount of sunshine and except for a few drops of rain
it remained dry the whole day and there was little wind.

It was hoped to see two species of Lepidoptera in particular: Plebejus
argus (L.) ssp. cretacea Tutt, the large chalk form of the silver-studded
blue, which had been taken before on the downs adjoining the wood by
Baron de Worms some years ago; and, the larva of Ptycholomoides
aeriferanus (H.-S.). We saw no sign of P. argus; indeed, butterflies were
remarkably scarce in this late year and this exceptionally cold and sunless
June. As for P. aeriferanus, search of the larches where P. Sokoloff found
the larvae in 1977 and bred two moths, revealed only one tenanted spinning
of the shoots, from which it was hoped an imago of the local Tortricoid
moth would emerge.

Among the more interesting moths noted were: Olindia schumacherana
(F.), Alabona geoffrella (L.), Strophedra nitidana (F.), Dichrorampha sequ-
ana (Hubn.), Coleophora laricella (Hiibn.) (cases on larch), Eana incanana
(Steph.) (many holed seed-heads of blue-bell (Endymion), but all empty
except one containing a full-grown larva), and Hydrelia flammeolaria
(Hufn.).

Mr. Dolling (British Museum) reparted the following Diptera: Mereodon
equestris (F.), narcissus fly; Orthoptera: Leptophyes punctatissimus (Bosc.),
and Hemiptera — Heteroptera: Psallus perrisi Wagner, Orthotylus nassatus
(F.), Stenodema laevigatum (L.), etc.

A new member, A. J. Halstead, coming over from Woking, reported
Diptera: Phytomyza ilicis Curtis on Ilex aquifolius, holly; P. sphondylii
(Rob. in G.) on hogweed, Agromyza nana (Meigen) on red clover, Taxomyia
taxi (Inch.), artichoke-gall-midge on yew, Jaapiella veronicae (Vall.), speed-
well gall-midge, Dasyneura glechomae (Kieff.) on ground ivy, and Iteomyia
capreae (Winn.) on Salix caprea, among other related Diptera. Also
Coleoptera: Gallerucella viburni (Payk.) extensively defoliating bushes of
Viburnum opulus (guelder rose), Rhynchaenus fagi (L.) (beech-leaf-mining
weevil); and the long-horn beetle Leiopus nebulosus (L.), also some Acarina
records (gall-mites on ash, field maple, etc.).

BOTLEY WOOD, HANTS. — Ist-2nd July 1978
Leader — Dr. J. R. LANGMAID

Twenty members and guests attended all or part of a day/night meeting
at this insect-rich area of woodland. f

The day was dull and rather cold; and unfortunately very little was seen
on the wing. Three species of figwort weevils were recorded, and ten species
of leafhoppers. In lepidoptera, an unsuccessful search was made for
Acosmetia caliginosa (Hiibn.), but all hope must not be abandoned for its
rediscovery here. Cases of nine species of Coleophora were found, including
those of C. vibicella (Hiibn.) and C. inulae Wocke.

As dusk fell the wind dropped, the temperature rose, as did the spirits of
the assembled company. The wood comfortably accommodated about ten
lights, and a very large number of moths came in. From the four members
who sent me a list of their captures and records, a total of two hundred and
fourteen species were recorded, including Choristoneura diversana (Hibn.)
(a new vice-county record), Pseudosciaphila branderiana (L.), Apotomis
lieana (D. & S.) = turbidana (Hibn.), Ancylis laetana (Fab.), A. obtusana
(Haw.), A. mitterbacheriana (D. & S.), Epinotia demarniana (F.v.R.),
Tethea or (D & S.), Euphyia unangulata (Haw.), Lobophora halterata
(Hufn.), Angerona prunaria (L.), Aethalura punctulata (D. & S.), Cucullia
verbasci (L.), and Elaphria venustula (Hiibn.).

Another new vice-county record was made earlier in the day when larvae
of Agonopterix scopariella (Hein.) were beaten from broom.

Our thanks are extended to the Forestry Commission for their courtesy
and helpful co-operation, and it is hoped to run another meeting here next
year.

CURRENT LITERATURE
BOOK REVIEWS

Catalogo sistematico doés macrolepidoépteros de Portugal by Maria Amélia
da Silva Cruz e Timétea Goncalves. Faculdade de Ciencias do Porto, 1977.
48 pp, no price stated.

This Catalogue meets a long felt want, as previous lists of Portuguese
Macrolepidoptera are very incomplete. It will be particularly interesting
to British lepidopterists because Portugal is one of the origins for many
species which are immigrants to Britain and Ireland, and also because its
fauna, at the extreme west of Europe, is well worth exploration by visitors.
The short introduction is given an English translation, and there is a useful
bibliography.

Under the title ‘‘Macrolepidoptera” the Psychidae (22 Portuguese species)
are included, but otherwise its scope agrees with that made familiar in
England by South. Vernacular names are not given. The scientific nomen-
clature is bizarre and in places out of date, since for different groups of
families it uses the work of five different authorities, dating variously from
1947 to 1970. Species are generally shown at nominotypical level without
indication of sub-species, except where two or more sub-species are stated

7/2) PROC. BRIT. ENT. NAT. HIST. SOC., 1979

to occur in Portugal: these are listed as separate taxa. Doubtful and
sporadically immigrant species are shown separately. There are too many
typographical errors: otherwise the printing and presentation is good.

The total number of taxa listed is about 1,000. This is much the same
number as would now appear in a British list compiled on the same basis;
but its composition is very different. On a rough count about 450 of the
accepted Portuguese taxa would not appear in such a British list. On the
other hand, Portugal lacks most of the Boreal and Euro-Siberian elements
which form a large part of the British fauna.

This Catalogue is a good beginning. We hope that the authors will continue
by giving some account of the distribution of species within Portugal, which
would reflect the considerable diversity of its climate and terrain. And they
might perhaps even tackle the Microlepidoptera also! R.F.B.

The Society’s Publications

ILLUSTRATED PAPERS ON BRITISH MICROLEPIDOPTERA

Still available, a small number of copies of the recently published volume
of twelve articles reprinted from the “South London” Proceedings between
1944 and 1957 with the twelve original colour plates.

These papers comprise LAMPRONIIDAE and ADELIDAE, LITHO-
COLLETIS and OECOPHORIDAE (three parts) and ALLIED FAMILIES
by S. N. A. Jacobs; PSYCHIDAE, PLUTELLIDAE and GLYPHIP-
TERYGIDAE and ALLIED GENERA by L. T. Ford; CALOPTILIA and
LYONETIIDAE by S. C. S. Brown; ERIOCRANIIDAE and MICROP-
TERYGIDAE by J. Heath and MOMPHA by S. Wakely. For ease of use
the pages and plates have been renumbered and are fully indexed
accordingly; in addition there is a new appendix drawing attention to
species belonging to these groups which have been added or sunk. There
is also a list of species which relates names used in the text to up-to-date
nomenclature and classification.

A limited edition of 500 copies was published in the Autumn of 1978,
bound in cloth, price £9; £6 to Members of the Society. Postage, where
applicable, 60p extra. Cheques should be sent to R. F. Bretherton, Esq.,
c.B., Folly Hill, Birtley Green, Bramley, Surrey.

A FIELD GUIDE TO THE
SMALLER BRITISH LEPIDOPTERA
The Society also announces the publication, probably in late summer
this year, of the above important and entirely new work, bringing up to
date and uniting the well-known Guide by the late L. T. Ford, B.a., and
the Supplement, both hitherto advertised on this page, with much additional
matter. Advice regarding price and purchase-procedure will be issed to
members at a meeting and also circulated, it is hoped, during the summer.

A LEPIDOPTERIST’S HANDBOOK

The Amateur Entomologist’s Society is pleased to announce the publication
of its latest Handbook, written by Richard Dickson. It is intended as a
‘vade mecum’ for both beginners and initiated lepidopterists and deals with
all aspects of the subject in a series of eleven chapters and four appendices.
There are 34 line illustrations and 13 photographs to augment the text and
the binding has been sewen to meet constant use.

It is apractical book on the various facets of breeding, collecting, storing,
conservation and photography of lepidoptera and should appeal to most
lepidopterist. Although the various techniques relate to the British fauna,
most are valid for lepidopterists anywhere.

The price is £3.00 plus postage and is avilable from A.E.S. Publication
Agent, 137 Gleneldon Road, London, SW16 2BQ. (An invoice will be sent
with orders, including postage).

THE INHERITANCE OF A PALE FORM OF GASTROPACHA
QUERCIFOLIA LINN. (LEPIDOPTERA: LASIOCAMPIDAE)

by

M. E. N. Maserus
(Department of Biological Sciences, University of Keele)

In volume 10 parts 1/2 of the Proceedings of the Society there occurs
the report that at the meeting of the Society on 25th November 1976, Col.
D. H. Sterling exhibited three spcimens of Gastropacha quercifolia Linn.
(Lappet Moth). These were described as follows: ‘The first a normal male
taken at light at Winchester in vii. 1975, the others, a light brown form,
probably ab. meridionalis Hormuz, unusual in England, and perhaps due
to the dry hot summer.’’ Although the report does not say so I assume
these two later specimens were also taken in July 1975 at Winchester.

In 1976 I took four specimens of Gastropacha quercifolia at light in
July, a further specimen being taken in August. All were captured in the
Ringwood area of Hampshire. Three of the moths were normal males, the
other two moths being a normal female and a pale female which seems to
be very similar to ab. meridionalis specimens in the British Museum
(Natural History). Both females were fertile and laid eggs.

The two resulting broods were reared, and to discover the method of
control of the pale form a number of crosses were obtained from the
resulting offspring.

Pairings of this species may be easily obtained by placing a three or four
“day”? old male in a hanging net cage with a freshly emerged female;
however, as with many other species, pairing will only occur if th cage is
hung outside so that it is subject to natural air movement.

One problem in rearing this species is that it usually passes the winter
as a larva on the stems of the foodplant or on withered leaves. This can
lead to a relatively high larval mortality in captivity, mainly due to
dehydration during this period. However the problem is partially offset by
the fact that the number of eggs laid is very high. In the broods in
question females laid on average over 500 ova, and according to South
(1939) in some cases females have been known to lay over a thousand. Due
to difficulty in over-wintering larvae all larvae were kept until they had
emerged from hibernation and recommenced feeding; however to keep the
number of larvae being reared within reason thereafter, approximately
half the surviving larvae from each brood (except broods 1 and 2) were
taken at random and released. All larvae were reared on sallow, and the
broods, though being reared separately were all raised under similar condi-
tions in an insectary in Egham, Surrey, so although protected from wind
and rain they were subject to natural temperatures.

The progeny reared from the two original light-trapped females (broods
1 and 2) were all normal in colour. Twelve further broods were produced
from the progeny of broods 1 and 2 (broods 3-14 inclusive), and six F.
generation broods (broods 15-20 inclusive) were also reared. The origins
and phenotypes of the parents and the phenotypes of the progeny of all
these broods are given in Table 1.

As the ratios between normal and pale forms varies between broods even
though all were reared under similar conditions, the results indicate that
the pale form is genetically controlled.

The progeny of brood 1, in which one parent was pale, were all typical
which indicates that, unless sex linkage is involved, the pale form must be
inherited as a recessive. The ratio between the two forms in broods 3-5
inclusive is approximately 15 typical to 1 pale in each case which suggests
that two unlinked bi-allelic genes are involved in the inheritance of the
pale form and that this form results when both genes are homozygous
Tecessive. To give the 15:1 ratios of typical:pale forms, the parents of these
three broods must all have been heterozygous for both the genes involved.
Consequently, the unknown parent of brood | must have been homozygous
dominant for both genes, and thus typical. The results of broods 15 and 16
lend further support to the hypothesis as only pale progeny are produced
from pale x pale crosses which is expected if the pale form is inherited as
a bi-factorial recessive and is thus pure-breeding for the pale allelomorphs.

In broods 6-14 inclusive all progeny were typical so it may be deduced
that one of the parents of these broods must have been homozygous
dominant for at least one of the genes in question, and as the progeny of
brood 1 would seem to have been heterozygous for both genes, then the
homozygous dominant parents must be those taken from brood 2 progeny.
Whether both genes are homozygous dominant in the parental stock of
brood 2 may not be ascertained from the progeny of either the F,
generation broods or the few relevant F, generation broods (broods 17-20
inclusive). However, the exact genotype of the brood 2 parents is of little
consequence in the determination of the inheritance of the pale form.

In conclusion it may be said that a pale form of Gastropacha quercifolia
which in appearance seems to be equivalent to ab. meridionalis is inherited
as a bi-factorial recessive the two genes involved being unlinked.

It thus seems that the most obvious implication of Col. D. H. Sterling’s
report, that ab. meridionalis may be controlled environmentally, being the
result of the dry summer in 1975, is unfounded. However, the report is
ambiguous due to its brevity. It may be that one or both of the alleles
which produce ab. meridionalis have the status of little more than rare
mutants in Britain where ab. meridionalis is generally at a disadvantage to
the typical form, the exact strength of the disadvantage being in some way
correlated to the oceanicity of the British climate. Thus as the climate in
Britain in 1975 and 1976 was far more continental and less oceanic than
usual, this may have led to the ab. meridionalis form being at less of a
selective disadvantage than in normal years, with the result that more
survived. In this way the occurrence of ab. meridionalis in Britain in 1975
and 1976 may be indirectly due to the hot dry summers of those years.

I would be interested to hear whether any other Lepidopterists obtained
pale forms of Gastropacha quercifolia in Britain during 1975/1976 or
indeed at any other time since 1967.

PLEBEJUS ARGUS (L.) (LEPIDOPTERA: LYCAENIDAE) IN MALTA
by JosepH L. CILIA
(‘Margerita’, Flat 1, Censu Busuttil Street, Fgura, Malta)

A male specimen of the Silver Studded Blue, Plebejus argus Linne. was
recently brought to light three years after its capture while examining
several papered specimens which were collected on 15th August 1975, from
Manoel Island. Manoel Island is a semi-urbanised island in the centre of
Marsamxett harbour connected by a bridge to the highly urbanised Sliema
area and across the harbour from Valletta. The occurance of this species in
this area is more probably a case of a sporadic visit.

Other records of various occasional visits by other species of butterflies
can be traced back to 1923 when Col. Harford recorded Danaus chrysippus
Linne. from Hastings Gardens on 4th June. This species was also recorded
on 10th April 1952 by Mr. A. Valletta who took two specimens and recently
on 17th October 1978 by Mr. G. Bonnett (personal communication). On
23rd May 1939 Hipparchia algirica Obth. was taken at Naxxar by Mr. A.
Valletta. The specimen was later described as a new subspecies (vallettai)
by G. De Lattin.

Mr. A. Valletta also recorded various other rare occurances. Polygonia
egea Cram. was taken on 20th March 1948 and Euchloe belemia Esp. on
Sth April 1979. In July 1963, K. A. Harrison took Catopsilia florella Fab.,
Euchloe ausonia Hub., Tarucus theophrastus Fab. and Philotes baton Bersgr.
Zizeeria knysna Trim was also taken by Mr. G. Bonnett on 12th March
1978.

ACKNOWLEDGMENTS

Many thanks are due to Mr. A. Valletta for confirming my identification
of the Silver Studded Blue, and also Mr. G. Bonnett for allowing me to
mention his new records.

A NOTE ON BREEDING THE PINION-SPOTTED PUG, EUPITHECIA
INSIGNIATA (HUBNER) LEP., GEOMETRIDAE)
by B. C. Jackson
(38 Asthall Gardens, Barkingside, Essex)

This rather uncommon insect may be found on the wing in May. If you
are fortunate enough to obtain a femle you should present her with a spray
of Hawthorn flowers to obtain the ova. As with many of the other ‘Pugs’
she will not part with her ova freely. I found that when she did she laid
them singly or in pairs on the edges of the petals of the Hawthorn. The
Ova are round in shape and pure white matching exactly the colour of the

PROC. BRIT. ENT. NAT. HIST. soc., 1979 Vd

Hawthorn petals. The larvae commence to emerge about a week after laying
and are of a very light green colour almost white. In the first instar they
feed on stamens and stigma of the flower. In the second instar the larva is
greyish white with a light brown line running down the whole length of the
back. Some of the larvae at this stage were eating the stamens and they
were standing erect from the base of the flower resembling the stamen
they had devoured. Some were also beginning to eat the fresh leaves of the
Hawthorn. In the third instar the larvae change to a light green colour
with a light brown line down the back, at this stage most of the flowers
have disappeared and they were feeding on the leaves. On 30.6.77 I
examined the larvae and found they were a half inch long, colour light
green and the dorsal line a reddish brown. They were now feeding on the
large leaves of the Hawthorn. When at rest some of the larvae stand erect
from the stems and blend in perfectly with the red and green of the
Hawthorn foliage, others had a tendency to hang from the underside of the
leaves with the head pointing downwards. On 6.7.77 the larvae entered their
final instar, they were then an inch long, ground colour bright leaf green,
the dorsal line was now broken up and resembled a row of arrow heads,
these were a deep reddish brown, they had a faint yellow sub-dorsal line.
There was also a reddish brown mark just above the anal claspers. On
18.7.77 larvae turned a darker bluish green colour before pupating.

They pupate one to two inches below the soil. The pupa is golden
yellowish brown with olive green wing cases.

A NATIONAL SCHEME FOR MONITORING THE ABUNDANCE
OF BUTTERFLIES: THE FIRST THREE YEARS
(with eight text figures)
E. POLLARD
(Institute of Terrestrial Ecology, Natural Environment Research Council,
Monks Wood Experimental Station, Abbots Ripton, Huntingdon, Cambs.)

INTRODUCTION

In 1973 regular transect counts of butterflies began in Monks Wood
N.N.R. in Cambridgeshire (Pollard et al 1975), with the aim of detecting
changes in the abundance of butterflies. In 1974 and 1975 counts were
made in a number of other sites in eastern England, as a pilot trial for a
national scheme. In 1976 a national scheme began, financed by the Nature
Conservancy Council and coordinated by the Institute of Terrestrial Ecology
at Monks Wood Experimental Station. This paper is an account of the
progress of the scheme in its first three years.

METHOD

Details of the method are available (Pollard 1977), and only a synopsis
is given here. A route through the study area is chosen and used for
regular counts from the beginning of April until the end of September. All
butterflies encountered within limits to the side of and in front of the
observer are recorded. Counts are made within specified times and there are
also minimum weather conditions below which counts are not made. The
season is divided into 26 recording weeks and the aim is to make at least
one count in each week. The transect routes are divided into sections so that
information is obtained on the distribution of butterflies along the route.

The mean weekly counts are used to calculate an index of abundance
for each brood of each species. An example is given to illustrate this, that
of the large white Pieris brassicae L. in.Monks Wood. (Fig. 1). This species
is probably not breeding in the wood so that, in this instance, the indices

reflect numbers passing through or stopping to feed at flowers. If the
different broods are not easy to distinguish then a combined seasonal index
value is given. For some species, we have evidence to show that the counts
are well correlated with actual abundance (Pollard 1977) but, for most, such
a relationship remains a ‘reasonable assumption’.

The index values are intended for year to year comparisons and not for
direct comparisons between sites. This is because the index value for a
particular species at a site depends very much on the route chosen.

There may be consistent differences between counts made by two
recorders at the same site, one producing higher or lower counts than
another. However the trends shown by different recorders at the same site
are similar.

SITES

The distribution of sites in 1978 is shown in Fig. 2. Only five sites have
been withdrawn from the scheme since 1976. The number is steadily
growing but it is considered that it is now close to the optimum. The range
of habitats is large, but semi-natural woodlands and grasslands predominate,
as the majority of sites are National Nature Reserves. Farmland, forestry
and urban areas are included but under-represented, as too are upland areas,
where weather conditions make a complete seasonal record impossible in
some years.

RESULTS
1. As site records.

At the simplest level the data provide a record, in a sense an inventory,
of the butterfly fauna of a site as represented by the transect. This aspect
of the data is illustrated in Fig. 3. Even if a transect is not repeated each
year this provides a record for that year, and a futher record can be made
after a lapse of several years.

The relationship between the distribution of adults on the transect route,
and their bredding areas will vary from species to species. For some, e.g. the
dingy skipper Erynnis tages L. or chalkhill blue Lysandra coridon Poda,
the agreement is likely to be very good. At the other extreme this sort of
data for the large white or red admiral Vanessa atalanta L. is likely to be
largely a reflection of the distribution of favoured flowers.

The information on the distribution of counts is valuable in assessing the
effect of habitat change on butterfly numbers at a site, as will be discussed
later.

2. Phenological data

As counts are made regularly through the season information on the
flight periods of butterflies is obtained. The peak flight period of the ringlet
at Monks Wood, for example (Table 1), was some three weeks later in the

is because of temperature dependent differences in rates of development of

species to have an effect on the mortality of these stages, as in cool seasons
individuals are available to predators, especially birds, for longer periods
(Thomas 1974, Pollard 1979). There are indications in the data that the
abundance of the ringlet is also affected by the earlyness of the season, but
the main influence on its numbers during this period is believed to have
been the 1976 drought.

In addition to comparing flight periods at one site in different seasons.
we can also look at geographical variation in one season. It is to be expected
that in more northern sites the emergence of adults will begin later than in
the south. Some selected data for the meadow brown Maniola jurtina L.
support this view in general (Fig. 4), although the flight period begins
later on the exposed Lindisfarne transect than at the two Scottish sites.
However the most striking feature is that at Kingley Vale, the earliest site,
the flight period is so protracted that it is also the latest site of those shown.
Inspection of the data for all sites where the species is sufficiently abundant
for the flight period to be determined (Fig. 5) shows that the long flight
period is a feature of all the sites on chalk soils. The chalk soils probably
warm up early in spring and so the early emergence is not surprising. How-
ever there is no obvious explanation for the very long flight period. The
monitoring scheme has revealed an intriguing problem which could well
reward further study.

3. Regional and national trends in abundance.

Methods are being considered for collating the data for a number of
sites to give overall regional or national trends in the index values. In the
illustration given (Fig. 6) the index values at individual sites have been
summed and the ratio calculated to express the change occurring between
successive broods. Similar ratios can be calculated for successive pairs of
broods, using in each case all the sites which have provided data for that
particular pair. If we then take as the starting point an arbitrary figure of
100 the ratios can be used to produce a collated index for a region or for
all sites. Essentially this is the method used to illustrate change in
the Common Bird Census (Bailey, 1967). The farmland sites in the
Common Bird Census are considered to provide an index applicable to
farmland in lowland Britain generally. The sites in the butterfly scheme are
highly biasted because of the large number of N.N.R.s. Nevertheless if, as
seems likely, year to year changes are dominated by weather conditions, the
changes in the collated index give a useful indication of the effect of
weather or any other factors acting over a wide area. Local effects can be
compared with this overall picture.

The regions used are those of the Nature Conservancy Council. If the
regional data suggest very different trends in different parts, as is the case
for the green-veined white Pieris napi L. (Fig. 6), then the national trend,
based on all sites is perhaps of little value. For many species however
trends have been similar over much of the country, although the large
number of southern sites means that the picture given is essentially for the
southern half of England and Wales.

There seems little doubt that the major influence on numbers of many
species during the short period of recording has been the 1976 drought.
This caused desiccation of larval food plants, while lack of moisture and
nectar was harmful to adults of many species. Species which showed major
declines in 1977, probably due to the drought in the previous year, were
the dingy skipper, large white, small copper Lycaena phlaeas L., common
blue Polyommatus icarus Rott., peacock Inachis io L., wall Lasiommata

megera L., speckled wood Pararge egeria L., and ringlet Aphantopus
hyperantus L. Some of the double brooded species, such as the large white
and common blue. showed some recovery in the second brood in 1977, and
the speckled wood, which has complex overlapping broods, also increased
towards the end of 1977. Although the summer of 1977 was cool and wet,
these increases suggest that some species were already recovering from the
drought.

The summer of 1978 was again generally a cool one, but many species
showed increased index values or little change. A further surprising feature
of a summer, with weather which would generally be considered very poor
for butterflies. was the enormous abundance of small whites Pieris rapae L.
and green-veined whites (Fig. 6) in eastern England. Several species which
appeared to suffer most from the 1976 drought showed large increases.

These included the green-veined white, speckled wood and ringlet which
are associated with cool, damp habitats and may have done well in the
damp summers of 1977 and 1978. Other drought affected species, the small
copper, common blue, and perhaps the wall, which may be more dependent
on sunny conditions have shown, at most, only small recoveries.

The similarity of trends over much of the country may be because of the
overriding influence so far of the 1976 drought. In 1978 however there
were a few clear regional differences. such as those for the green-veined
white and the small white which were abundant in the east, while the
small skipper Thymelicus sylvestris Poda declined in the east but increased
in the west. 1978 was also notable for the small number of migrants. The
trends for the red admiral (Fig. 6) and painted lady Vanessa cardui have
been very uniform over the whole country, as might be expected.

4. Trends at individual sites

The regional and national trends, apart from their intrinsic value, will
provide a background against which data from individual sites can be
assessed. The period of recording is as yet too short to expect to learn much
of the effects of habitat change on butterflies. A possible approach to this
topic can be illustrated however by using the longer series of east midland
data.

Monks Wood N.N.R. has been subject to considerable change during the
period of recording 1973-78. This has mainly taken the form of ride widen-
ing. The wood was, until this century, managed by traditional coppice
methods, giving a cycle of cutting which ensured that in any one vear
some part of the wood had been cleared. This type of management is
believed to have helped to maintain the rich flora and fauna associated with
many of our old woodlands. Since the abandonment of coppicing, Monks
Wood, in common with many other similar woods has lost a number of its
butterfly species. We cannot be sure that this is directly the result of
changes in management but it seems likely that they are at least partly
responsible. Since Monks Wood became a N.N.R. in 1953 there has been
small scale resumption of coppicing but also, more recently, considerable
opening up of rides. This has involved cutting many of the shrubs and trees
within a Sm band either side of the rides in an attempt to improve the
conditions available for the plants and animals of open woodland, including
butterflies. Most of this management has been in the transect recording
period and so provides an opportunity to gauge the early effects. Other ride

management consists of cutting the ride edge vegetation on a rotational
basis every few years, but this is probably of minor importance compared
with the widening of the rides.

The trends in index values for Monks Wood for the 1974-78 period can
be compared with the collated index from the sites in the East Anglia,
East Midland region (excluding Monks Wood). This has been done for just
three species to provide an illustration (Fig. 7). It is clear that for the wall
the Monks Wood trends are largely determined by what is happening in the
region as a whole. The increase in numbers of walls at some sites in 1978
was not shown at Monks Wood and it is possible that the species is
temporarily absent from the wood. The peacock shows fluctuations in
Monks Wood which are not closely related to the regional picture. This is
not unexpected, particularly for the summer indices, as the local abundance
of flowers is so important. In 1978 the peacock had a very high summer
index value in Monks Wood. This was probably the result of the large
number of teasels Dipsacus fullonum L. in flower in the wood. The teasel
is a biennial and seeded well on the bare ground of some rides during the
1976 drought. It is likely that this effect will be temporary.

The meadow brown seems to have increased in Monks Wood rather more
chan it has in the area generally. Visual comparison of trends gives only
an indication of differences but a more formal comparison of the annual
changes suggests that this is a small but real difference. We can move
from this comparison with other sites to an inspection of data from the
Monks Wood transect itself. Fig. 8 shows the index values for the meadow
brown over the period of the six sections which have been subject to ride
widening. There is no doubt that adults become more abundant in
rides after widening. It seems that the numbers may rise to a peak two or
three years after widening and then there is a decline, suggesting that the
benefit for this species may be short lived. The evidence still falls short of
a proof of a beneficial effect of the management on breeding populations,
but it seems a reasonable assumption that this is the case.

Of the other species in the wood only one, the hedge brown Pyronia
tithonus L. shows a similar increase to that of the meadow brown, while
the ringlet and speckled wood have shown relative declines. The latter
species are associated with the shadier rides of the wood and have probably
been adversely affected by management.

The effect of the ride-widening must be said to be somewhat limited
so far, the majority of species showing no obvious response in terms of the
index value in the wood. A number do show redistribution within the rides
however and it is likely that in the longer term the management will
begin to show more benefits.

DISCUSSION

After three years it may be said that the Butterfly Monitoring Scheme is
successfully established. Eventually it should be possible to quantify changes
in butterfly abundance over a sufficiently long period to be able to investigate
the effects of weather conditions and other factors on annual fluctuations,
as Beirne (1955) and others have attempted previously with the qualitative
data available to them.

The method is not however without its problems and these should not be

forgotten in interpreting the results. The most serious of these problems
are:

(1) There is undoubtedly an influence of weather on the flight of
butterflies, above the minima adopted for recording. In most cases this
means that the warmer and sunnier the weather the more butterflies will
be recorded. There is also some evidence that at very high temperatures
the flight of some species is reduced and so the counts depressed. It is
believed that these effects are usually small compared with that due to real
changes in abundance, but for some species they may be important. This
problem does not affect the comparison between individual site and regional
indices.

(2) The counts are of adults, but the real interest is in breeding areas.
Adults of some species are nearly always found in close proximity to their
breeding areas, others are not. In the latter species the index values will
be greatly affected by the presence of nectar sources, and are a reflection
of these as well as the general abundance of the species in the area.

((3) As a result of the transect counts we have good data on changes
in butterfly abundance, but comparatively poor information on changes
in habitats. Gross changes, such as those due to management or accidental
fires, are known but detailed vegetational changes are not, as botanical
monitoring is generally impossible because of the time and labour required.

The local recorders and reserve managers, in the case of nature reserves,
will therefore be particularly important in helping to interpret the effects
of habitat changes on the index values.

The results from monitoring may help to indicate the causes of fluctua-
tions by showing correlations with weather conditions or habitat changes
and will also highlight problems for further investigation. An understanding
of the processes involved in population changes can, however, only be
obtained by intensive studies of individual species. Such studies must include
not just the adults, but all stages of the life cycle, any one of which may
be important in a particular case.

A major advantage of monitoring lies in the fact that we will know what
is happening while it is happening and: while it is possible to take action
for the conservation of species. In addition there will be a data bank
available, so that ideas resulting from research can be tested using informa-
tion from a range of sites over a long period of time.

ACKNOWLEGMENT

I would like to thank the Nature Conservancy Council, all of the

THE BUTTERFLIES AND HAWK-MOTHS OF
EASTERN SAUDI ARABIA

(with Plate VII and One Map [Plate VIII])
by A. R. PITTAWway

(1S Beech Hall Road, Highams Park, London E4 9NJ)

Although described as desert or desert-steppe, the natural vegetation and
topography of eastern Saudi Arabia is quite varied, ranging from shifting
sand-dunes, fertile oases, rocky, barren plains, to true steppe.

Virtually all the rain (50 to 150 mm.) falls between November and April,
during which period the windspeeds and cloud-cover are also at their
greatest. These are also the coolest months of the year, day temperatures
ranging from 17 to 27°C and at night, between 3 and 19°C. During the
hottest months—June to early October, day temperatures rise to between
37 and 58°C, while at night they rarely drop below 30 degrees.

PROC. BRIT. ENT. NAT. HIST. Soc., 1979 91

Thus, it is not surprising that most plant life away from the oases comes
to life after the rains, but before the onset of searing temperatures, i.e.
January to May. This is reflected in many of the butterflies’ life-histories,
described from observations made during 1977 and 1978.

PAPILIONIDAE

Papilio demoleus Linné.
RANGE: From Saudi Arabia and Mesopotamia across sub-tropical and tropi-
cal Asia to northern Australia.

Within Saudi Arabia, common in the oases of Safwa, Qatif, Tarut Island,
Al Hassa and various wadis along the Tuwayq Hills, especially Wadi
Hanifa to the west of Riyadh.

ADULT: 92-106 mm.

A strong flyer, sailing and soaring over Citrus groves, along tracks, as
well as between date-palms, where it is greatly attracted to the flowers of
root brassicas and Lantana.

This species, which varies from oasis to oasis, is on the wing from mid

February to early December in a succession of overlapping broods. Scarce
at the beginning of its flight period, numbers build up in April.
EARLY STAGES: Citrus species, especially Lemon and Mandarine, are the
only foodplants. On these, the glossy yellow and domed eggs are laid singly
on young leaves of a growing tip, never old leaves. Besides being very
conspicuous, they are also locally numerous as many females will select
the same bush for oviposition, with young saplings being preferred.

Newly hatched larvae resemble those of P. machaon L., i.e. black with
a white saddle, and spiny. This colour scheme lasts into the fourth instar,
as does the habit of resting and feeding exposed on top of a leaf.

With the next skin change green becomes the dominant colour dorsally,
white ventrally, with a brown and white chequered anterior band over the
50 mm. body.

Now it feeds secretly, hiding away amongst twigs and leaves when at rest.

The 25-35 mm. pupa is formed amongst these twigs. However, if on a
sapling, then on the main stem. Many are destroyed during the winter
months due to the activities of parasites and bacterial disease. Even so,
large numbers still survive.

A number of colour forms are evident—green and yellow, light brown
and purple, and whitish brown with dark brown markings.

Papilio machaon Linné.
RANGE: Across the Palearctic and northern Nearctic in a multitude of
subspecies.

In eastern Saudi Arabia confined to the Al Hassa Oasis, as well as on
Tarut Island, where it was introduced in the winter of 1977/78.

Eller originally named this population ssp. arabensis, but gave no
description or type locality. Examination of a number of individuals shows
quite clearly that this Saudi population is but an isolated colony of Papilio
machaon syriacus Verity.

However, Al Hassa examples do have broader and more curved tails than
Mesopotamian specimens.

Occasionally, in summer, some individuals resemble subspecies muetingi
Seyer from Iran will turn up in other areas.

P. machaon frequents cultivated date-palm areas, especially those border-
ing Lucerne fields, where it forms definite breeding colonies.

92 PROC. BRIT. ENT. NAT. HIST. soc., 1979

ADULT: 84-98 mm.

Found from late November to mid April in a number of overlapping
broods, usually four. Commonest during January and February.

Flying quite fast along partially shaded tracks, or over cultivated fields,
it frequently stops to sip nectar at the flowers of root brassicas and sweet
basil (Ocimum basilicum).

Impregnated females have a more leisurely flight, stopping ever so often
to investigate clumps of fennel (Foeniculum vulgare), or sun themselves
during the coldest month.

Later on, when warmer weather sets in, most fly in the shade amongst
date-palms.

EARLY STAGES: Fennel and Haplophyllum tuberculatum (Rutaceae) are the
foodplants. As the former is an introduction, it is possible that this species
once fed solely on the latter.

On these, the glossy yellow and domed eggs are laid, either all over small
seedlings in fields, or on the lower and outer leaves of larger growths.

During midwinter, plants growing in full sunlight are preferred. However.
come March, some sort of shade is sought for part of the day.

The larvae cannot be distinguished from those of P. machaon gorganus
Fruhstorfer in all stages.

Those feeding on fennel generally eat the lower and older leaves, while
on Haplophyllum, both leaves and flowers are avidly taken by all instars.

On the latter as many as nine larvae per plant have been found, ranging
from newly emerged to fully grown individuals.

Pupae are formed away from the foodplants, amongst shrublets, on tree-
trunks, or on the irrigation channels. These are identical to those of ssp.
gorganus from central Europe, with both green and brown forms.

PIERIDAE
Pieris (= Artogeia) rapae (L.)
Recorded as a winter and spring migrant as far south as Riyadh along
the Tuwayq Hills. Larval foodplant: — cultivated cabbage.

Euchloe belemia Esper.
RANGE: From north-west Africa and south-west Europe across North
Africa, Saudi Arabia to Mesopotamia and Iran.

Found in the bush and grass strewn coastal sand-dunes, as well as the
Rhanterium and camel-grass steppe areas on the eastern coast, from Abu
Hadriyah to Al Mish’ab. Small numbers also occur in the Tarut Island and
Qatif Oases.

ADULTS: 38-46 mm.

On the wing from mid January to mid March in two or three broods,
this fast, strong and sig-zagging flyer stays close to the ground, often follow-
ing definable courses repeatedly. It is greatly attracted by earth ridges
supporting larger than normal numbers of annual Cruciferae. In very strong
winds most seek shelter on the ground behind a grass tussock.

EARLY STAGES: The seed-pods of tall annual Cruciferae—Sinapis, Brassica
and Sisymbrium are the commonest foodplants. In Qatif Oasis, the isolated
population exists solely on the pods of cultivated root brassicas.

Young larvae are bluish green with a profusion of black bristles. Fully
grown at between 45 and 50 mm., they are striped longitudinally purple,
white and greenish yellow, with short, black bristles, and very thin.

PROC. BRIT. ENT. NAT. HIST. soc., 1979 93

They rest along the narrow seed-pods of their foodplant when not con-
suming them, with up to five per plant being common.

The 20-22 mm. pupae are similar to those of the European Orange Tip
(Anthocharis cardamines L.), but more cylindrical and browish grey.
These are formed away from the foodplant, usually amongst Rhanterium.

Euchloe falloui Allard.
RANGE: North Africa across to Sudan, and central Arabia where it is found
in small, isolated colonies along the Tuwayq Hills, frequenting open, flat,
salt free, rocky desert-steppe, epecially mini plateaus separated by wadis.
ADULT: 36-38 mm.

Very similar in behaviour to E. belemia, but not such a fast flyer. As
many of each species resemble each other, genitalia comparisons should be
undertaken.

Pontia glauconome Klug.
RANGE: From Somalia north to Lybia and east to Arabia.

In eastern Saudi Arabia, almost anywhere where rocky outcrops occur,
i.e. the rocky plains and hills to the north, west and south of Riyadh, as
well as around Dhahran, Khobar and the Al Hassa Oasis.

Favours rocky wadis and their surrounding gullies as well as sandy areas
with perennial Cruciferae (Zilla).

ADULT: 43-46 mm.

Very fast, zig-zagging, low flying species which often settles at Cruciferae
flowers bordering abandoned date plantations.

Common from early March to early December in a multitude of over-
lapping broods, which differ from area to area, depending on the rains. In
some favourable localities, e.g. the Tuwayq Hill wadis, it often abounds in
May and October.

(Overwinters as a maturing larva or pupa on its foodplants.)

EARLY STAGES: Although most often found on the shrubby Ochradenus
species (Resedaceae), larvae also feed on Reseda (where it occurs), Zilla,
Diplotaxis harra and Moricandia sinaica, (the latter only around Riyadh in
the spring), taking leaves, flowers and seed-pods with equal relish.

It is on these plants that the pale creamy white, conical, ribbed eggs are
laid singly, either on the flowerstalks (Zilla), or leaf surface (Ochradenus).

Full grown larvae (30-40 mm.) which are very similar to those of Pontia
daplidice L., feed quite openly, with up to five or six individuals per plant
being common.

The 16-20 mm. pupae are again very similar to those of P. daplidice and
are formed head downwards at the base of a shoot, usually on the main
stem at the approach of winter. Summer brood pupae may be found any-
where on the plant and be of a china-white colour.

Colias crocea (Geoffroy)
RANGE: Across southern and central Europe to North Africa, Iran and
Saudi Arabia.

Common in the Tuwayq Hills; abundant in all major, cultivated, eastern
oases—Al Hassa, Qatif, Tarut Island and Safwa, favouring the Lucerne
(Medicago sativa) fields.

Small, isolated populations also exist around Manifa, north of Jubail, on
beds of annual, winter legumes growing in hollows between coastal sand-
dunes. These populations are also supplemented by migrants.

ADULT: 48-54 mm.

Occurs from December to early May, but at Manifa only during February

and March.

94 PROC. BRIT. ENT. NAT. HIST. soc., 1979

Has a very characteristic to and fro flight over low vegetation, where it
frequently settles at sweet basil (Ocimum basilicum) flowers in the oases.
EARLY STAGES: Medicago sativa, Sesbania and various annual trefoils and
vetches are this species’ foodplants, whose larvae and pupae are identical to
European examples.

Anaphaeis aurota Fabricius
RANGE: From subsaharan Africa across Saudi Arabia to Syria, India and
Ceylon (Sri Lanka).

In this region a small, isolated population exists on Tarut Island. There
is then a large break before it reappears in the easterly Tuwayq Hills, from
Al Kharj to Buraydah, where it frequents abandoned date plantations in
oases, or wadis. It is especially common in Wadi Hanifa to the west of
Riyadh.

Although it may occur over a large area, aurota inhabits definite, large
colonies whose fortunes wax and wane due to heavy predation.

ADULT: 53-58 mm.

A powerful flyer, dashing between date-palms, across clearings, or over
the ground, where it frequently settles. Often stops to sip nectar at flowers.

Observed from mid November to mid April, with three peaks: — late
November, mid to late January and late March.

EARLY STAGES: Capparis species, but only those in or near oases, are the
foodplants on which the pale yellow, conical and heavily ribbed eggs are
laid in groups of up to 30 on the leaf underside of growing shoots, with
often more than four batches per shoot. After a few days they turn orange,
then grey prior to emergence.

Larvae are greyish green when young, covered in dark bristles and highly
gregarious.

Fully grown specimens (35 mm.) are mid grey with a broad, greenish
yellow dorsal band and yellowish underside. Two very distinct features are
the long, pale, ventral hairs, and small orange spots which cover the whole
body. Once this size and colour, most are very inactive, spending much of
their time sunbathing.

Pupae are approx. 17 mm. long and very like those of Pieris brassicae L.,
but basically grey, or green, with darker markings and a greenish dorsal
band. The orange spots, so noticeable in the larvae, are even more con-
spicuous.

Formed at the base of a shoot in most cases.

Colotis liagore Klug

RANGE: From Mauretania through Arabia to Baluchistan. In eastern Saudi
Arabia, only found in the Tuwayq Hills along the sides of deep, rocky
wadis.

ADULTS: 32-36 mm.

Tends to fly up and down, or along, the cliff walls, keeping to a given
route. Many frequently settle on the ground in the shade of some bush,
where they are ambushed by others patrolling the same area.

Easily confused with a small P. glauconome Klug at a distance, as this
species is on the wing during the brief March and April flight time of
liagore.

EARLY STAGES: Capparis species growing on cliff faces—C. cartilaginea:
never those species in plantations, are selected as foodplants.

Colotis fausta Olivier

RANGE: From Egypt through Arabia, Iraq, southern Iran to India and Ceylon
(Sri Lanka).

PROC. BRIT. ENT. NAT. HIST. Soc., 1979 95

Found in the same areas as A. aurota, i.e. Tarut Island and the Twuayq
Hills. Common to the west of Riyadh in Wadi Hanifa.

Occurs as ssp. fausta, closely resembling specimens from Mesopotamia
and also found in similar habitats—the edges of cultivated fields, or
abandoned date plantations, where Capparis has colonised.

ADULT: 48-50 mm.

A very fast flyer, and solitary, dashing very close to the ground, on which
it frequently settles with wings closed Dorsally, it resembles a pinkish
orange C. crocea Geoff.

Observed in Wadi Hanifa from mid November to mid May. On Tarut
Island, only seen during January and February in very limited numbers.
EARLY STAGES: Feeds on Capparis, especially spinosa.

Catopsilla florella Fabricius
RANGE: From the Canary Islands across subsaharan Africa, through Egypt
and Arabia to India and China.

Only found in the Tuwayq Hills west and north of Riyadh, frequenting
wadis with abandoned date plantations and sand-bars.

ADULT: 65-75 mm.

A very fast and direct flyer, most often seen dashing along the edges of
plantations. However, it is rare and may only be a migrant in this area,
ocurring in April, although in western Saudi Arabia (Jiddah) it flies from
March to July.

EARLY STAGES: Cassia italica,.a small shrub found in wadis, is the only
foodplant in the eastern region.

The eggs, which are almost identical to those of C. crocea Geoff., are
laid on the upper and lower surfaces of this plants leaves.

Full grown larvae (40-45 mm.) are dorsally leaf green with cross-lines of
fine, dark, bristle bearing tubercles. A double lateral line of black and
yellow is present. Head leaf green with fine, black spots. This colour scheme
provides good camouflage amongst the flowerheads and leaves where they
rest.

Eurema hecabe Boisduval
RANGE: Right across subsaharan Africa and tropical Asia to Japan in
numerous subspecies.

In eastern Saudi Arabia, confined to the oases around Qatif and on
Tarut Island as ssp. senegalensis Bdv., frequenting the edges of cultivated
fields, especially those of Lucerne. However, in Qatif Oasis, where it is
less common, individuals are often seen flying between date-palms on
overgrown, abandoned plots.

ADULT: 40-44 mm.

A weak flyer, staying close to the ground where it often settles amongst
the Lucerne.

It is also an avid visitor of nectariferous flowers, especially sweet basil,
from which it feeds for lengthy periods.

The generations are identical in appearance, the species flying from
December to mid May, with two peaks: — one during January and the
other in late March.

EARLY STAGES: The sole foodplant of this species is Sesbania sesban, an
introduced, small, upright tree similar to Laburnum in many respects,
especially the flowers, but not the pinnate leaves.

Small, isolated saplings situated in sunlight dappled clearings, or field

96 PROC. BRIT. ENT. NAT. HIST. soc., 1979

borders, are selected on which to lay the yellow, conical and heavily ribbed
single eggs, which turn orange prior to hatching.

Fully grown larvae (30-33 mm.) are very similar to those of C. crocea
Geoff., (which can also be found on the same plant), but are thin, cylin-
drical and lack any trace of red along the yellow lateral line. Otherwise,
they are dark green, including the head, and covered in fine, black bristles.

Most rest along a leaf midrib, on the upperside, where thy are very
well camouflaged.

The pupa (15 mm.) is, again, very similar to that of C. crocea, but more
finely proportioned and pale green. Usually formed under a leaf if hatching
soon; otherwise at the trees base.

DANAIDAE
Danaus chrysippus Linné.
RANGE: From the Canary Islands right across Africa, Arabia, tropical Asia
to Australia.

Found all over the rocky central region of Saudi Arabia, as well as all
large oases and most of the coastal area in the east, i.e. the Tuwayq Hills,
Al Hassa, Khobar, Dhahran, Qatif, Tarut Island, Safwa and the Manifa
sand-hills.

ADULT: 74-78 mm.

A slow, lazy flyer, abundant in well vegetated wadis around Riyadh where
it flies all year round. However, in the east it is only on the wing from
February until November, overwintering as a feeding larva or pupa.
EARLY STAGES: The large, broadly conical, pale yellowish white, ribbed ova
are laid singly on the underside of a young leaf, with various Asclepia-
daceae being selected for this—Pergularia tomentosa around Riyadh;
Calotropis procera both there and in Dhahran; a plant resembling Vince-
toxicum in the eastern oases, and Leptadenia pyrotechnica on the Manifa
sand-hills.

On these black, vellow and white banded, tentacled larvae feed up
rapidly before pupating beneath a leaf as a pale blue, gold speckled pupae.

NYMPHALIDAE
Melitaea persea Kollar
RANGE: Lebanon,S. Turkey, Syria, Iraq, Iran and Saudi Arabia.

In the latter country only found in the Tuwayq Hills, where it is very
common to the west and north of Riyadh as ssp. sargon Hemming, frequent-
ing the rock strewn beds of dry wadis, especially those with sheltering cliffs.
Occurs in definite colonies
ADULTS: 38-50 mm.

Flight very typical of the genus, being interrupted by frequent stops on
the ground, or on Anvillea garcini to feed. Wing patterning and colour
variable, as well as the first generation being darker and more heavily
spotted.

On the wing from early March to mid April in two broods—early March
and the first two weeks of April. Each brood only flies for a very short
period.

EARLY STAGES: Teucrium oliverianum (desert germander) is the sole food-
plant, being a perennial herb which is often abundant, carpeting some wadis
with their salvia-like, purple flowers.

The larvae (see Plate VII) are sometimes very common on this plant,
some areas being completely stripped of leaves, flowers, as well as seedpods.
Fully grown at between 30 and 35 mm., the larvae are typical of the genus,

PROC. BRIT. ENT. NAT. HIST. sSoc., 1979 97

being white with dark cross stripes and bright orange dorsal cones. Like
most Melitaea larvae, these will curl up and fall into the tangled mass of
their foodplants base when disturbed.

Pupae (12-15 mm.) are also typically Melitaea—pearly white with small
black and tan specks. These are formed at the foodplant’s base, although
many of the first generation hang fully exposed on the upper stems, where
they form up in a week.

Junonia (= Precis) orithya (L.)
RANGE: Subsaharan Africa across Arabia to tropical Asia.

In eastern Saudi Arabia it is confined to cultivated oases in the Tuwayq
Hills, as well as in the eastern coast region—Al Hassa, Khobar, Dammam,
Qatif, Tarut Island and Safwa, where it shows a preference for field edges,
fallow fields and the clear areas beneath date-palms.

ADULT: 43-50 mm.

A very conspicous species and very common, either flying rapidly in the
shade of trees, sunning on bare ground, or sipping nectar from Vernonia
shrubs. Many are also attracted to overripe dates which have fallen on the
ground.

J. orithya flies all year round, but is most common from April to
November.

EARLY STAGES: Convolvulus species, especially arvensis plants at the edge of,
or in, fields, are the foodplants on which the blue-green, domed and heavily
ribbed eggs are laid singly.

Fully grown larvae (35-40 mm.) are black with fine white speckling and 3
mass of blackish spines. The black head has an orange ring behind it, a
dorsal line of the same colour extending from there to the anal claspers.

Many sit fully exposed on the ground inbetween eating small holes in
their foodplants leaves, with older ones being preferred.

The pupae (15 mm.) are pale greyish brown and similar to those of
Vanessa atalanta L., both in shape and deportment. They are formed on
the stalk of some nearby dead plant.

Vanessa cardui (L.)
RANGE: Throughout the subtropics and tropics, except South America,
where it occurs as a sporadic migrant.

It is as a migrant that this species occurs all over eastern Saudi Arabia,
but it is only resident in the Tuwayq wadis and large eastern oases, and
from the Rhanterium/Camel-grass steppe north and northwestwards to
Kuwait and Iraq.

ADULT: 54-56 mm.

Has a very characteristic and straight flight, but it often settles on the
ground to sun with wings open. Many are attracted to flowers, especially
the large Vernonia shrubs of the east coast oases, these blooming during
the insects flight period—November to April in up to four broods, with
February producing most adults.

EARLY STAGES. The spiny yellow and brown larvae are identical to european
examples, but feed on Urtica urens around Riyadh; but on Malva eagyptia

and, especially, Neurada procumbens (Rosaceae) in the east coast steppes
and sand-hills.

LYCAENIDAE
Lampides boeticus (L.)

RANGE: In the tropics and subtropics of the Old World.
In this region it is confined to the cultivated oases of Safwa, Qatif, Tarut

98 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

Island, Dammam, Khobar, Al Hassa and the Tuwayq Hills, being rare in
the latter locality.

Frequents the fringes of cultivated fields, gardens, road reservations and
islands, and rocky gorges fringing cutivated wadis.

ADULT: 30-34 mm.

At certain times of the year an abundant species, flitting around its food-
plants on which it frequently settles, or even feeds from, especially in the
case of Sesbania sesban.

Alternatively, to be seen dashing along some plantation edge, or city
street, in search of flowers, or a place to deposit eggs.

Its flight time usually coincides with the flowering of its foodplants, but
small numbers can be found throughout the year. Three main broods are
evident: — one in December and the other two in March and April.
EARLY STAGES: The pillbox shaped, china white and heavily sculptured eggs
are laid on the sepals or immature pods of the foodplants flowers, and are
often extremely abundant. The most common foodplant is Sebania sesban.
However, as this plant does not occur in Al Hassa and the Tuwayq Hills,
the pods of Phaseolus are taken in the former, those of Astragalus in the
latter.

On hatching, the young larva immediately bores into the pod where it
proceeds to feed on the immature seeds. Pupation also occurs within the
pod.

Zizeeria karsandra Mre.

RANGE: From Africa and the southern Iberian Peninsula across the Middle
East and tropical Asia to Australia.

In eastern Saudia Arabia, mainly confined to the cultivated oases of Jubail
Safwa, Qatif, Tarut Island, Dammam, Khobar, Al Hassa and the Tuwyq
Hills. A few isolated colonies exist along the coast to Kuwait where rain-
water accumulations between coastal sand-dunes alow trefoils and vetches
to grow during the winter months, e.g. Manifa and the island of Abu Ali.

ADULT: 18-22 mm.

Probably the commonest butterfly in the region. Abounding over Lucerne
fields, it flies very close to the ground, often in groups which frequently
settle on low vegetation. Where flowers occur, especially Vernonia and
sweet basil, this species smothers them, often driving off competing bees.
Amongst sand-dunes, population densities are much lower.

In the oases this species is continuously brooded throughout the year, but
becomes uncommon during the cooler months of December, January and
February. However, on the sand-dunes, where its foodplants are seasonal,
only one or two broods occur during March and early April, but this is
dependent on the rainfall.

EARLY STAGES: The 8 mm. larva is typically lycaenid; pale olive green with
a number of faint, coral red bars and arrow marks dorsally. The small head
is black.

It feeds quite openly on a shoots tip, preferring cultivated Lucerne
(Medicago sativa). Prior to its introduction, various Alhagi species were
probably taken in the easterly oases, and still are. It is also found on
related, annual species such as Lotus and Trigonella.

Pupae, which are approx. 6 mm. long, are attached to the underside of
a leaf or stem, and exhibit the same colouration as the larvae. In shape it
resembles that of the common blue (Polymmatus icarus Rottemburg).

PROC. BRIT. ENT. NAT. HIST. soc., 1979 99
Tarucus rosaceus Austaut
RANGE: From North Africa across Arabia to Iraq and Iran.

In this region it is confined to oases, having been found at Jubail, Safwa,
Qatif, Tarut Island, Khobar, Al Hassa, Salasil and various wadis criss-
crossing the Tuwayq Hills. On no occasion was 7. theophrastus Fab. found.
ADULT: 22-26 mm.

A species which occurs in marked colonies. Each adopt a particular
Zizyphus tree, around which they fly, frequently settling on the leaves and
flowers. Many also rest on the dead twigs and shoots of herbaceous plants
nearby, which is where most sleep.

Apart from the flowers of its foodplant, individuals have been observed
sipping nectar from fennel (F. vulgare) and Heliotropium.

T. rosaceus flies throughout the year in a number of well defined broods,
although it is commonest in October and during March and April.

EARLY STAGES: The larval foodplant is Zizyphus.

Agrodiaetus loewii Zeller
RANGE: Turkey, Syria, Lebanon, Jordan and Arabia.

In Saudi Arabia it is only found in the Tuwayq Hills and thence eastwards
up to the Ad Dahna sand-dunes, inhabiting any kind of water course in the
stony desert, so long as Astragalus spinosus is present. However, it does
favour the same large, stony wadis that M. persea Kollar is found in.
ADULT: 34-38 mm.

A very fast flyer occurring at very low population densities. Often seen
dashing in tight circles around Astragalus bushes, on whose flowers it
settles.

It is on the wing from early March to mid April in two generations; these
coinciding with the flowering of its foodplants:— A. spinosus and A.
sieberi, especially the former.

Chilades galba Lederer
RANGE: From southern Turkey southwards through the Middle East,
Afghanistan, Mesopotamia to southern Arabia.

In this region it occurs in the Tuwayq Hills along the edges of date
plantations in sandy wadis.
ADULT: 22-24 mm.

Flies close to the ground under date-palms, or around Prosopis bushes.
Many often settle for lengthy periods on shaded bare earth, or grass, during
hot weather.

This species is very easily confused with a tailess Chilades parrhasius
Feb., with which it flies from mid April to mid May.

EARLY STAGES: Most probably feeds on Prosopis, a known foodplant which
is common in many localities.

Chilades parrhasius Fabricius
RANGE: From India and Arabia north to Afghanistan.

In this area confined to the wadis along the Tuwayq Hills, preferring the
edges of date plantations, especially abandoned ones with a profusion of
flowers.

ADULT: 22-24 mm.

Nearly always found amongst date-palms, sunning on, and feeding from,
bush Compositeae.

It is very easily overlooked, or confused with Lampides boeticus L. and
Chilades galba Lederer, with which it flies from mid April to mid May.

HESPERIIDAE
Gegenes nostrodamus Fabricius
RANGE: Circum-Mediterranean, through Asia Minor, Arabia to Turkestan
and India.

100 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

In eastern Saudi Arabia it occurs in the oases of Safwa, Qatif, Al Hassa
and the Tuwayq Hills.
ADULT: 30-33 mm.

This rapid flying species, which is on the wing all year round, but as
three or four well defined generations, is most often seen resting on the
leaf of some broad-leaved shrub, or feeding from Lantana.

EARLY STAGES: As with most hesperids, the larvae feed on grasses.

Pelopidas thrax Hubner
RANGE: Africa, the eastern Mediterranean, Egypt, Arabia, Iran to India
and Penang as two separate subspecies.

In eastern Saudi Arabia it occurs as ssp. thrax in the oases of Safwa,
Qatif, Tarut Island, Al Hassa and the Tuwayq Hills.

ADULT: 40 mm.

Quite a common species, but only really noticed when at rest on a leaf,
or feeding from Jasminum and Lantana blossom. Flies for most of the
year.

EARLY STAGES: The larvae feed on most course grasses.

SPHINGIDAE
Acherontia styx styx Westwood
Rare in the large Al Hassa Oasis to the north and east of Hofuf, where
it flies in February, May, July and September as four separate generations.
Larvae only found on Withania somnifera (L.) Dun. (Solanaceae),
although it may also feed on the widely cultivated Aubergine.

Agrius convolvuli convolvuli (L.)

A common species, but confined to the neighbourhood of large towns
and oases, having been found at Al Hassa, Khobar, Dammam, Qatif, Tarut
Island and in the Tuwayq Hills.

Flies from April to November in up to four clearly defined broods, with
the first yielding the largest individuals.

Larvae on Convolvulus in oases, especially those plants growing along
the edges of cultivated fields. In towns, only on ornamental Ipomoea species
growing over walls.

Daphnis nerii nerii (L.)

Common in all major east coast oases—Al Khobar, Qatif, Tarut Island
and Al Hassa, flying from January to June, which is the flowering period
of its foodplant. Three overlapping generations have been recorded.

Larvae on Nerium oleander, where they usually take the flowers and
young shoots. The brown form is common.

Hyles lineata livornica (Espet.)

An abundant species, being especially common (breeding) along the east
coast sea-dunes and in the patches of Rhanterium/Camel grass steppe to
the north and west of Manifa. The largest individuals, however, were
recorded from the fringes of Al Hassa Oasis.

Flies from November until April, with most occurring in January and
February. Multi-brooded.

Larvae common on the seedheads of Asphodelus fistulosa, less commonly
on Polygonaceae and tendrilled, annual Leguminosae.

Hippotion celerio celerio (L.)
A common oases species, having been found at Al Hassa, Qatif and

Tarut Island from November until June in up to four distinct generations.
Larvae only on Vitis.

OBITUARIES

DR. HENRY BERNARD DAVIS KETTLEWELL

Bernard Kettlewell was born on 24th February, 1907 at Howden, East
Yorks., the son of a member of the corn exchange. He went to school at
Old College, Windermere and Charterhouse, and then studied for medicine
at Gonville and Caius College, Cambridge and Barts Hospital.

The Cambridge University Natural History Society at that time had
about 200 members and subdivided into several disciplines. In the entomo-
logical section, the zoology students mingled amicably with the amateur
lepidopterists (students of medicine, the sciences or the arts), and among
the latter Bernard’s charm and energy made him a natural leader. There
was, of course, another older oracle among the bug-hunters, namely
Harold Worsley Wood, brother of a don and living in retirement in De
Freville Avenue, Chesterton. Probably due to Wood’s influence, Bernard
joined the “South London” in 1928. Contact with Dr. E. A. Cockyne, then
still practising as a doctor in London, and other leading lepidopterists of
the day was a natural consequence.

Most of the undergraduates owned bicycles; these put Wicken Fen within
Tange, and those, who wished, could obtain an exeat from their tutor and
spend a night bug-hunting in the Fen under arrangements of keeper Barnes.
Bernard’s fast car enabled him and a few friends to range even further
afield, to find vernal larvae of the black hairstreak, Fixsenia pruni (L.) at
Warboys Wood, or the vernal flier Carterocephalus palaemon (Pallas), the
chequered skipper at Bedford Purlieus on the Great North Road north of
Stilton. During his 1928 vacations with R. P. Demuth he took Coscinia
cribraria (L.) at Bournemouth and bred from it in 1931; in the summer of
1930 he joined the writer in lodgings at Cox’s Staithe, Barton Turf, Norfolk,
to obtain other local rarities. These pursuits in no wise impeded the
acquiring of an M.A. and an M.B.

During the next few years he disappeared from East Anglia acquiring
in London his medical qualifications (B.Chir., M.R.C.S., L.R.C.P.) and
becoming engaged, in Birmingham, where his parents now resided, to
Hazel Wiltshire. The marriage took place in 1936 when he joined a medical
practice at Cranleigh, Surrey; he lived there at ““Homefield’’, The Common.

Throughout this period he continued field entomology and breeding and
began to publish results and observations of increasing interest. A series
of articles in the Entomologist’s Record, Vols. 51-64 (1939-52) dealt par-
ticularly with the natural history and breeding of the less well-known

102 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

British lepidoptera. Two important papers with colour-plates appeared in
our Society’s (the South London) Proceedings: A survey of the insect
Panaxia dominula (L.) (1942-3: 1-49) and Temperature experiments on the
pupa of Heliothis peltigera Schiff. . . . with the manifestation of the
Mendelian law at a given temperature only” (1943: 69-81). In the latter
he introduced his concept of the pupal ‘“‘passiphase’’ and ‘‘actiphase”’;
temperature changes during the former had no effect on subsequent
imaginal pigmentation, but during the latter were responsible for degree
of pigmentation laid down. As contacts with his Cambridge friends declined,
those with Dr. Cockayne and E. B. Ford led to this increasing interest in
the genetics of British lepidoptera.

The inauguration of the National Health Service in 1946, however, was
a shock for Bernard, and he ceased to be a general practitioner, becoming,
for a while, an anaesthetist in the Emergency Medical Service; then, the
idea of a radically new life lured him and his family abroad. He accordingly
presented his lepidoptera collection to the British Museum of Natural
History in 1947 and departed for South Africa, where he travelled and
collected widely. These collections also eventually came to the British
Museum. Persuaded by E. B. Ford he returned after a few years to cloudier
skies and genetics at Oxford, giving up all thought of continuing in
medicine; in 1952 he was awarded a Nuffield Research Fellowship there,
and thus his greatest period began; his penetrating intelligence enabled him
to fit naturally into the highest academic circles, despite what a friend
described as his “rugged individualism”’.

His experiments with birds and melanic moths soon enabled him to
unveil the causes of ‘industrial melanism’’, which he showed to be due
not to the chemical effects of breathing polluted air or eating polluted
food, but to natural selection mainly by bird predators in a visually polluted
environment. A flood of articles followed, mainly in Heredity and other
specialist papers; they are listed in his principal book (“‘The evolution of
melanism”, Oxford 1973) but this was still to be written, for his first book,
a popular work, appeared in 1963 (‘Your book of butterflies and moths’’,
Faber) to be followed by a joint work with Julian Huxley: ‘““Charles Darwin
and his world’? (Thames and Hudson, 1965).

In connection with the Darwin centenary he visited Brazil in 1958 there
photographing and collecting the rich and colourful moths of the rain
forest close to Rio de Janeiro, an episode in which the writer had the good
fortune to accompany him, at least in his activities in the Corcovado rain
forests. ‘“‘Life’’, the American picture magazine, printed a big feature on
3rd November, 1958: ‘“‘Darwin’s insects jewels of his jungle paradise”,
mainly remarkable for its illustrations, of which the colour photos were
Bernard’s own work, while the paintings were by Walter Linsenmaier; no
less remarkable however was one black and white photograph of Bernard
himself at his light-trap, veiled by a kite-net, stripped to the waist and
covered with moths. Another account of this collecting at the Corcovado
hotel, was penned and illustrated by the humorist Ludwig Bemelmans;
here he figures as “the professor” and is again portrayed, more decently
clad but equally surrounded with moths, in his eyrie, in a striking water-
colour drawing; this appeared in an article “The best way to see Rio” in
“Holiday”, December 1958. “Discovery” also printed an illustrated account
of his expedition, giving more space to its scientific significance, and the
British Museum again received the collection.

His British collection had meanwhile become merged with those of
Cockayne and Rothschild; as the “R.C.K.” collection it proved to be a
Mecca for students of the variations of British moths; later still this
became part of the “National collection” at South Kensington as David
Carter reported in our last number (11 (1/):19-23).

Soon after this he visited the Shetlands repeatedly to study the case of
Paradiarsia glareosa (Esper) whose melanic form edda (Staudinger) in
Unst shows reduced flight activity, is concentrated in the north end of the
Shetlands, and appears to be less subject to predation by gulls than the
typical form (see Heredity 16(4):415-434) (1961). Typically he toiled single-
handed to produce his great work, ““The Evolution of Melanism”’ (1973), a
labour that lasted longer than expected and left him exhausted. He retired
from his main appointment in 1976, becoming a senior officer in the
University Zoology Department and an Emeritus Fellow of Wolfson
College. His usual ebullience faded as ill-health and suffering made his
retirement less fruitful than hoped; our Society made him an Honorary
Member in February 1977, an act of appreciation which consoled him but
could not arrest the decline. The end came in May 1979 at the age of 72.

During his Oxford life he had resided at the Old Vicarage, Steeple
Barton, and he introduced into its garden a rare strain of the scarlet tiger
moth (P. dominula) which multiplied and survived him there. Perhaps the
local naturalists’ trust will be able to ensure its continuance there. In any
case his memorial remains, in his collections and written work. But his
enthusiasm and encouragement will be sadly missed by many.

E.P.W.

N. D. RILEY, C.B.E.

Norman Denbigh Riley was born at Tooting, London, on the 26th
September, 1890 and was educated at Harlington School, Balham (1898-
1904) and at Dulwich College (1904-1909). From an early age he showed
an intense interest in Natural History, and on leaving Dulwich took up
the position of Demonstrator in entomology at Imperial College of Science
in 1911. Later that year he joined the staff of the British Museum (Natural
History) at South Kensington, London as an Assistant in charge of the
Rhopalocera (Butterflies) in the Department of Zoology. The Department
of Entomology housing all the Insecta did not come into being until two
years later in 1913.

During the First World War, Riley reached the rank of Captain, serving
in the Army Service Corps and The Queens Regiment from 1914-1919 and
was mentioned in dispatches. On his return to civilian life he resumed his
work on the butterflies at the Natural History Muesum. His adminstrative
ability became evident and he took over the Keepership of the Department
of Entomology in 1932, the post which he so ably held for twenty-two years
a record—until his retirement in 1955. Though he retired two decades ago
he still continued to visit the Museum almost daily to work on the collec-
tions and to give freely the benefit of his vast experience to those who
requested it.

During the long period as head of the Department containing the largest
insect collection in the world he organized the dispersal, for safety reasons,
of the major parts of this vast collection during World War II and their
re-assembly afterwards. He was made a C.B.E. in 1952.

He was the senior member of the South London Entomological and
Natural History Society (now the British E. & N.H.S.) having joined in

104 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

1908. He was President in 1923 and 1924 and was elected a Special Life
Member in 1959. He was elected a Fellow of the Royal Entomological
Society of London in 1912 and served as an Officer of that Society on
many occasions. He was a Council member in 1921-23, 1930,, 1933-35 and
1953, Hon. Treasurer 1939-40, Hon. Secretary 1926-29, 1941-50, Vice-
President 1929, 1949 and 1953, President in 1951 and 1952, and was elected
an Honorary Fellow in 1957. He was also a Fellow or member of many
other learned bodies concerned with Natural Science, Entomology, Conser-
vation and Nomenclature. He was elected a Fellow of the Zoological Society
of London in 1919 and was its Vice-President in 1958 and 1959. He was
President and Vice-President of the Lepidopterist’s Society and an Honorary
member of the Entomological Society of France. He served as a Commis-
sioner on the International Commission on Zoological Nomenclature and
was one of the editors of the International Code drawn up by that body.
He was also both Secretary and then Treasurer of the Society for the
Promotion of Nature Reserves for many years. He was the Royal Entomo-
logical Society’s representative on the Council of the National Trust and
was also Chairman of the Entomological Section of the International
Union of Biological Sciences and of the Permanent Committee of the
International Congresses of Entomology. The above list is not exhaustive
but just some of the more important posts he held with such distinction.

Throughout an exceedingly busy life he found time to edit The Entomo-
logist—the first journal to be devoted entirely to entomology—for nearly
forty years. During his editorship a steady stream of taxonomic papers,
notes, observations, obituaries and reviews issued from his fluent pen. He
published numerous scientific papers devoted almost exclusively to the
Rhopalocera of the World in other journals as well and was the author of
several books on this subject. Amongst these are the Field Guide to the
Butterflies of the West Indies and as a co-author with L. G. Higgins of
the extremely popular Field Guide to the Butterflies of Britain and Europe,
published by Collins in 1970 which is already in its second edition and has
appeared in eight different European language editions. A bibiography of
all the above is appended.

PROCEEDINGS

Thursday, 11th January, 1979
The President, Mr. G. Prior, in the chair.

The President announced with great regret the death of Mr. Cecil Haxby,
a member since 1958, and a frequent exhibitor formerly. He also welcomed
a visitor from Europe, Dr. Gerhardt Tarmann, of Innsbruck, Austria.

EXHIBITS

Rev. D. AGAssiz — Two further introduced species of Nymphuline moths
(Lep. Pyralidae) from aquatic nurseries at Enfield: (i) Oligostigma poly-
dectalis Walker, a single specimen taken on 26th October, 1978; probably
imported from Singapore, although most specimens in the British Museum
are from Australia; and (ii) an unidentified Nymphula species closely
related to N. enixalis Swin. This species has been present throughout this
year and has become very numerous.

Dr. A. A. ALLEN — (i) Three spp. of Pyralidae, all obtained in the Bruns-
wick Square area of Central London: (a) Pyrausta aurata (Scopoli) found
with many others, flying in sunshine around mint growing in St. George’s
gardens; in Britain more often regarded as a chalk downland species; (b)
an example of Plodia interunctella (Hibner) captured 18.ix.1975 in a
chemical laboratory at the Royal Free Hospital School of Medicine; and
(c) a moth thought to be an Ephestia, whose determination was discussed
later, bred from a larva found in a slight web on top of a russet apple
21.xi.1975. The apple was stored at room temperature during the winter
and the larva pupated in the spring without feeding. (ii) two British spp.
of the Ichneumonid sub-family Alomyinae (Hym.) namely Alomya debel-
lator F. and A. semiflava Stephens, all ¢ ¢. A. debellator was captured
by Mr. L. Packer on 10.vi. 1975 at Parks, Oxford, while the exhibitor
captured the other species, in the company of others, on 26.viii.1978 at
Arundel, Sussex, by sweeping. Both spp. are common, at least in the south
but apparently the hosts are unknown. The hind-wing venational character
which mainly distinguishes the two species was also illustrated. (iii) A dried
example of the flower of Atropa belladonna L. (Solanaceae), deadly night-
shade, taken 9.vii.1978 on chalk downs near Gomshall, Surrey.

Col. A. M. Emmet — Eight adults of Epinotia fraternana (Haworth) (Lep.
Tortricidae) reared from larvae on Abies grandis and taken at Chalkney
Wood, Essex. A smill piece of branch shewing larval feeding was exhibited
on 28.ix.70. The larvae and subsequent pupae were kept indoors in a room
with moderate central heating and 22 imagines emerged between 21.xi.78
and 5.i.79, apparently without diapause. There were no parasites. Epinotia
subsequana (Haworth) was less rare on the same tree.

MEMBERSHIP

The following names were read for the first time: Messrs. D. G.
Brotheridge and G. M. Hollins. The following, their names having been
read for the second time, were duly declared elected members: Messrs.
T. A. Wickett, B.Sc., F.R.A.S., and P. H. Sterling; Miss Celia Haddon,
M.A., and Miss Helen Wilk; and the Dundee Museum and Art Galleries.
The obligation book was signed by Mr. Shepheard and Master Geoffrey
Burton.

PROC. BRIT. ENT. NAT. HIST. SoOc., 1979 113

Mr. W. G. Tremewan in an illustrated talk then discussed the life-
histories of seven British species of Burnet moths, viz., Zygaena exulans
(Hohenwarth), Z. loti (D. & S.), Z.viciae (D. & S.), Z. Filipendulae (L.),
Z. trifolii (Esper), Z. lonicerae (Scheven and Z. purpuralis (Brunnich).
Transparencies depicted the biotopes of the species and the adults, cocoons,
larvae and hostplants, in Britain. The numerous and interested audience
put many questions to the lecturer at the conclusion of his talk, and much
further information was given during a fairly long question-time.

COMMENTS ON EXHIBITS

S. N. Jacobs thought that the moth exhibited by Dr. Allen which he
thought an Ephestia sp., was in fact Cryptoblabes gnidiella (Mill.) and
Col. A. M. Emmet concurred. The usual foodplant reported for it was
pomegranate. Regarding the flower of A. belladonna, 8. N. Jacobs said
this species was common in the heart of Bromley, Kent, and had been for
many years; J. M. Chalmers-Hunt said is was very common on chalk
downs at Eynsford and he had also seen it on the Dartford marshes, also
in Kent. G. Prior said he had seen it by the roadside at Rickmansworth.
Col. A. M. Emmet said that P. aurata was often reported as a pest on
mint.

25th January, 1979

Inclement weather and trouble on the railways prevented most members
from attending this meeting, which was to have been the Annual General
Meeting. After telephonic consultation with officers of the Society, the
President proposed that the Annual General Meeting be adjourned until
8th February. This was agreed by the members present, nem. com.

EXHIBITS

S. N. A. Jacops —a greetings card reproducing the coloured illustration
of a double blue hyacinth and Nigella (Love in the mist) by Nicolas Robert
(1614-1685) estimated about 1660, embellished by a “Blue Spotted Brim-
stone” (Papilio ecclipsis) and a larva feeding on the Hyacinth leaves. This
fraudulent insect is mentioned by Col. Cowan in his article in the
Entomologist’s Record 90:302.

P. VeRDOoN— A large, and as yet unidentified, hymenopterous parasite
reared from a cocoon of Mimas tilae (L).

E. S. BrapForp — Specimens of microlepidoptera he was presenting to
the Society’s collection, including Niditinea piercella (Bent.), from a Tawny
Owl nest at East Blean, Kent; Eudonia angustea (Curtis) from Moss at
Faversham, Kent and Yponomeuta vigintipuntata (Retz.) from Sedum
telephium (Orpine) at Boreham Wood, Herts.

COMMUNICATIONS AND COMMENTS ON EXHIBITS

Rey. Agassiz pointed out that Orpine, the foodplant of vigintipunctata,
was a scarce plant, but the moth was in his experience commoner than the
foodplant. Possibly the moth ultilised an alternative foodplant, such as a
small Sedum. Mr. Stubbs mentioned a Hoverfly which mined the leaves of
Orpine in Norway, but appeared to be associated with Pennywort in the
South West of England. Mr. Bradford agreed that alternative natural food-
plants were probable, and mentioned the diverse nature of foodplants of
some Lepidoptera. He instanced Teleiodes paripunctella (Thunb.), a
Gelechiid normally associated with Oak that had been bred by Mr. R.
Heckford from Myrica gale L. in Scotland. Mr. Evans pointed out how
little was known about the natural foodplants of many of our insects,
including some of the more common macrolepidoptera.

114 PROC. BRIT. ENT. NAT. HIST. soc., 1979

A general discussion ensued on foodplants, the merits of recording
distribution of lepidoptera, and the techniques for labelling specimens in a
collection. The evening concluded with Mr. Prior showing a comprehensive
set of slides of the larvae of British Eupithecinae, including some of the
rarer species. He outlined some aspects of their life history, and answered
questions on various aspects of “‘Pugs’’.

Thursday 8th February 1979
107th ANNUAL GENERAL MEETING

(with which was combined the Ordinary Meeting)
The President, Mr. G. Prior in the chair.

The President announced to those present that the Annual General Meet-
ing held on 25th January, had been adjourned until the present session, due
to inability of most officers to be present at the earlier occasion.

He also announced with regret the death, at the age of 91, of B. C. S.
Warren, a resident at Folkestone and an international authority on the
Rhopalocera, though not a member of the Society.

EXHIBITS

E. S. BRADFORD — an example of Oncocera obductella (Z.), taken 1976
at Blean, Kent, three specimens of Leucoptera laburnella Staint. bred from
a stunted laburnum tree infested with its larvae, and three examples of
Hedya nubiferana (Haworth), one typical and two melanic; the latter were
from Rothamsted trap at Horrogate, Yorks.

A. J. HaLSTEAD — the comb of a bees’ nest found in the open air at
Wisley Gardens. In early September 1978 a small cluster of Apis mellifera
(L.) was noticed at 15ft. above ground on a branch of Pinus radiata and
was kept under observation until mid November when the last bee died of
exposure. When first noticed they were clustered on a piece of comb
6in. x Sin. which suggested they had already been there some time. Normally
bee swarms only remain in the open for a few days before moving on to a
more suitable nesting site. From a previous observation he concluded that
such open-air nests can be constructed with a viable queen present, but in
this instance it appears the nest had lost its queen.

J. HeatH — Maps prepared by the Biological Records Centre of: the
distribution in Britain of Plemyria rubiginata (D. & S.), Lycia lapponaria
scotica (Harr.), Psodos coracina (Esp.), Serraca punctinalis (Scop.), Pseudo-
panthera macularia (L.), and Scopula marginepunctata (Goepe) (= con-
jugata Borkh.).

MEMBERSHIP

The following, their names have been duly read a second time, were
declared elected members: D. J. Brotheridge, G. N. Hollins.

The Obligation Book was signed by I. F. G. McLean.

ANNOUNCEMENTS

The Secretary announced that the Deparment of the Environment pro-
posed to add to Schedule 1 of the act protecting British Lepidoptera
Thetidia smaragdaria (Fabr.) (the Essex Emerald Moth).

COMMUNICATIONS

Col. M. Emmet said that a further volume on the Moths and Butterflies
of Great Britain and Ireland would appear later this year and would be
accompanied by a supplement regarding addenda and corrigenda on those
species included in Vol. 1. He invited those with new Vice County records
for Lepidoptera to send them to him for inclusion.

MATTERS ARISING OUT OF THE MINUTES OF THE PREVIOUS A.G.M.

Mr. J. Heath stated that he had consulted a Kodak engineer regarding
the proposal to make slide copies of old style slides and hoped that this
could be arranged in due course.

The Secretary then read the Council’s Report. J. M. Chalmers-Hunt
seconded its adoption which was passed. The Treasurer read his report
which was seconded by Rev. Agassiz and adopted. The Editor then read
his report which Mr. S. N. Jacobs seconded and it was adopted. In the
absence of Dr. Allen the Secretary read his report whose adoption was
seconded by R. Fairclough, and passed. The Curator then read his report
which Col. A. M. Emmet seconded; the Librarian’s report was likewise
passed; and Col. Emmet then read his report on the Prof. Hering Memorial
Fund which Rev. D. Agassiz seconded, and these two were also passed.

The President invited proposals or questions from the floor under Bye-
law 25(b) without evoking any suggestion or proposal from members
present. He then declared the following elected for 1979: President, the
Rev. D. J. L. Agassiz, M.A.; Vice-Presidents: G. Prior, F.L.S., F.R.E.S.
and R. Fairclough, F.R.E.S., F.R.H.S.; Treasurer: Col. D. H. Sterling,

The President then read his report and his address. He then inducted the
new President to the chair. The latter proposed a vote of thanks to his
predecessor for all his work on the Society's behalf and expressed the hope
that his address would be published in the Society’s Proceedings. Motions
thanking the Treasurer and other officers for their work were also passed.

COUNCIL’S REPORT

Your Council is pleased to report 1978 as a year of excellent progress.
Membership reached 731 in December. Eight of our members died and
will be mentioned later by the President.

A revised “‘economy’” membership list was produced with the help of
The Rev. D. Agassiz. This was necessitated by heavy expenditure on other
publications. Four parts of our Proceedings were published which have
earned our Editor hearty congratulations. Also, thanks largely to the drive
of Mr. Agassiz, we were able to publish the bound collection of illustrated
papers on Micro-lepidoptera from past Proceedings in time for distribution
at the Exhibition, with the financial assistance of several of our members.
The New Field Guide, a greatly amplified revision of Ford’s Guide, is now
in the hands of our printers. Council wish to thank Mr. Tubbs, Col. Emmet
the Editor, and his team of specialists, for the efforts they have made to
produce this, and all the benefactors and typists to gave assistance.

The Annual Dinner, once again well organised by Dr. MacNulty, was held
at Imperial College, and the 66 members and guests who attended enjoyed
a delightful evening. In the hope of increasing attendance next year Council
solicits the aid of Ordinary Members to offer hospitality to Country
Members for the night of the Dinner, so that many who come to the
Exhibition will be able to attend both functions.

The Annual Exhibition at Chelsea Old Town Hall was most successful.
in spite of the poorness of the season. There were over 100 exhibits and

116 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

some 300 signed the attendance book. The very high quality of the exhibits
maintained our usual tradition. The refreshments, organised by Mrs.
Murphy, with the help of a dedicated team of volunteers, including our
two youngest members, was appreciated by all and our thanks are due
to them and to Mr. Ken Evans who was in charge of the Exhibition. We
also thank Mr. Ventom for selling our Christmas cards, this year’s beautiful
design by Mr. Dyke being very well received, Mr. Wilson, who devoted so
much effort to photographing the exhibits, and to many others behind the
scenes including our team of reporters.

The Society owes so much to our Treasurer, Mr. Bretherton, who has
asked to be relieved of his Office this year. He has guided our finances
through this difficult time of inflation, has imposed a wise watch on
Council’s spending and has done so much for the Society in many other
ways for which we are deeply grateful. We wish Col. Sterling, our new
Treasurer every success.

Dr. Allen, our librarian, has had to resign becouse of pressure of other
work but Mr. Prior has volunteered to take over from him for which we
are most grateful.

Mr. Else again produced an interesting and varied programme of 21
indoor meetings which have been well attended and much enjoyed. A new
venture this year was a joint meeting with the Royal Entomological Society
of London who entertained us at Queen’s Gate in an atmosphere redolent
of spiced wine and good Fellowship. We hope to reciprocate this year and
to make a regular fixture of what was a most enjoyable event.

Fourteen Field meetings, seven of which were two day fixtures, were
organised by Mr. Wild. These were attended, in most cases, by many more
members than usual, and produced some interesting records.

Council has devoted some time this year to making its views known on
the proposed Amendments to the Parliamentary Bill on Plant and Animal
Conservation and has taken what action was possible. It is also trying to
establish a happier modus vivendi with the Forestry Commission by seeking
active cooperation and simplified access procedure to their woodlands.

Hon. SEc.

TREASURER’S REPORT, 1978

The Accounts for 1978 have been prepared and audited under difficult
conditions, and I warmly thank our auditors, Mr. Messenger and Mr.
Stoughton-Harris, for completing their approval in time. I also thank Mr.
Wakely for his care of the subscriptions work as Assistant Treasurer.

The Publications Account, which always covers our largest expenditure,
this time includees the cost of publishing the “Illustrated Papers on Micro-
lepidoptera’’; which was £981, with about £50 postage, but against this we
had income from sales of it of £1,570. This remarkable result was largely
due to efficient organisation by our President elect, the Rev. David Agassiz.
I also thank three members for interest-free loans of £600, which they
generously contributed to bridge the time gap between cost and receipts. In
the event, this was short, and they have now been repaid. Printing the
Proceedings for 1978 cost more than last year, and our ordinary sales, at
£454, were much below the abnormal figure of 1977; but the combined
result is another welcome reduction in the charge to the Income and
Expenditure Account, to £893.

The Income and Expenditure Account shows a surplus of £470; but
without the saving from the “Illustrated Papers’’, mentioned above, there

PROC. BRIT. ENT. NAT. HIST. soc., 1979 117

would have been a small deficit. Our ordinary administrative expenditure
was almost unchanged; but the Special Funds have taken more interest as
a result of the large transfers to Reserve which were made last year. On the
income side, interest from investments, bank deposit, our new holding of
£1,000 in Post Office Savings Investment Account is well up at £1,102, and
Christmas Cards, Ties, and the Annual Dinner show useful surpluses,
though rather smaller than in 1977, But there is the very disturbing feature
that, despite an increase in membership, income from subscriptions is,
at £1,763, actually £64 Jess than last year. This was mainly because the
arrears have become larger. Inspite of much use of ink and postage by
the Assistant Treasurer; some 90 members had failed to pay their suscrip-
tions, due on Ist January, by the end of 1978, and many had not paid even
for 1977. In the face of this fact, I cannot describe the year’s results as
more than moderately satisfactory.

On the assets side of the Balance Sheet, there was a small addition to the
Midland Bank shares held for the Hering Memorial Fund, and the cash
position was built up in preparation for financing the new ‘‘Field Guide
to the Smaller British Lepidoptera”, which is now with the printers. On
the liabilities side, the Housing and Reserve Funds spent nothing and
increased their balances by receipt of interest; and the Library and Hering
Memorial Funds also spent less than their income. The General Fund, with
the addition of the surplus on Income and Expenditure Account, now
stands at £4,863.

I have been Treasurer for ten years, and it is time that both the Society
and I should have achange. Colonel Sterling is well equipped by experience;
he will bring a fresh mind to the work; I hope he can simplify it; and I
wish him every success.

EDITOR’S REPORT

The 1978 Proceedings were again printed in two double parts appearing
in April and November, the latter double part being a month later than
planned due to a printer’s break-down. At the request of some members
and the Council, the title-page was reintroduced; not counting this, 138
pages of text were printed, a total of ten more than 1977. Of the seven art
plates, five were of lepidoptera, and two were obituary portraits. The index
is in press and will shortly be distributed.

A French colleague once remarked that entomology was a dialogue des
sourds (a conversation between the deaf); there is a degree of metaphorical
truth in that remark, particularly due to the specialisation and ever
deepening and widening of contemporary knowledge. Our Proceedings
endeavour to strike and, I hope, do achieve, a balance between the interests
of the main body, with whom touch should not be lost, and the discoveries
of the advance guards. The Rhopalocera figured most prominently in 1978
and may well do so again in 1979. Once again our Proceedings (Indoor
Meeting) and Field Meeting reports occupied about one-third of our text
space and, as last year, contained many important and interesting observa-
tions of species of various orders.

The assistance, before or after printing, of Dr. Southwood and Messrs.
Howard, Tweedie and Uffen in checking our manuscripts and proofs, is
gratefully acknowledged.

CURATOR’S REPORT

My report this year is one of steady progress in the Society’s affairs.
The Torstenius collection of Scandinavian lepidoptera is at present being
accommodated in a ten-drawer Hill unit, earmarked for that purpose some

time ago. It is hoped to make available one, or possibly two more Hill
units for this collection in due course as it may require that amount of
drawer space to house it when complete. The collection comprises several
thousand specimens. The task of arranging it is being undertaken by Mr.
C. B. Ashby. Several drawers, already laid out, were displayed at the
Annual Exhibition at Chelsea Town Hall on 28th October, 1978. We have
to thank Mr. Ashby for the display which was visually interesting and
informative.

While on this subject I would like to bring to the attention of members
that Mr. Torstenius desires specimens of various races or sub-species of
British lepidoptera. The Society’s collections contain few of those species
required, so I appeal to members to make available from their own
collections specimens that can be presented to Mr. Torstenius, and to
contact either Mr. C. B. Ashby or myself on his requirements.

Good headway is being made with the new Diptera cabinet considering
the large number of specimens involved. The transference of the Massee
collectio nof Coleoptera is well on its way to completion.

The use of he duplicate collections over the past year has depleted the
stocks somewhat. It is hoped to provide more spcimens this year, including
the microlepidoptera. The Rhopalocera are one group rarely available as
duplicates. In fact the Society would be pleased to receive donations of
butterflies, especially geographical races or sub-species. Those from the
more remote regions of the Britsh Isles being particularly welcome.
Duplicate Coleoptera are available. Those members wishing to know more
about them please contact Mr. R. D. Weal.

I would like here ot enquire of a box of 35mm colour transparencies
depicting larvae of the British Lepidoptera, that are, I believe on loan.
Would the member who is at present in possession of them return them
as soon as possible.

The few items of equipment surplus to the Society’s needs were sold by
Mr. M. Ventom at the Annual Exhibition.

Donations were made to the Society’s collections during the year and the
thanks of the Society are due to the following for their contributions: Mr.
E. Gower-Scopes (Coleoptera), Mr. B. F. Skinner (Lepidoptera), Col. A. M.
Emmet (Lepidoptera), Mr. R. D. Weal (Coleoptera), Mr. M. Chalmers-
Hunt (Lepidoptera), Mr. E. S. Bradford (Lepidoptera).

Once again I wish to thank Mr. R. D. Weal, Mr. C. B. Ashby, Mr. W.
Parker, Mr. P. J. Chandler, Mr. B. F. Skinner and other members for their
valuable assistance during the year; also to Mr. L. Christie for his con-
tinued help in the collating and packaging of the Society’s proceedings.

LIBRARIAN’S REPORT

During the past year the library has undergone extensive revision. The
numerous unsorted Journals have mostly been helved in chronological
order, thereby enabling members to obtain a desired reference quickly and
efficiently, instead of searching laboriously through piles of disarranged
literature. All of the more widely-read Journals are readily accessible,
together with a representative selection of less familiar publications.

With the acquisition of more shelving space, all of the Journals taken by
the Society will be available on meeting-nights—an ambition also derived
from gradual loose case binding of the Journals—of which the appearance
and shelf-life will accordingly be improved. The generosity of Mr. G. Prior
is very much appreciated in this context.

PROC. BRIT. ENT. NAT. HIST. SoOc., 1979 121

A lot of work remains to be done, chiefly on the books at present far
too many are disorganized — often by virtue of their large size. This feature
merely emphasizes the urgent need for spacious shelves in the limited room
available.

More generally, too many books are still retained by their borrowers
for a period in excess of that allowed under the Society’s By-Laws: the
present period of two months (for a maximum of three books) is deemed
to be of sufficient duration. It is essential that books are returned before
they become overdue; it is up to the member concerned to act in a
responsible manner.

As the year has advanced, the pressure of work has increased to such a
degree that I am compelled to resign my tenure of office. I would like
to thank Council for their support during this critical period of redevelop-
ment within the library.

I conclude my report by listing the publications generously donated to the
library in 1978. They include: —

‘Records of my life work in Entomology’ — C. R. Sacken: from E. W.
Classey; ‘1977 Records of Fareham group of Entomologist: Lepidoptera’
Appleton, Carpenter, et al: from E. W. Classey; ‘Butterflies on my mind’
— Dulcie Gray; ‘Abberations of British Butterflies’ Russwurm: from E.
W. Classey; ‘Gardens of Buckingham Palace’ — P. Coats: donated by the
author; ‘Life on 40 acres’ — Barry Moore: from E. W. Classey; ‘British
Tortricoid Moths’ — Bradley, Tremewan and Smith: from Miss Wakely;
‘The British Butterflies’ — R. Dennis: donated by the author; ‘Endodontoid
Land Snails from Pacific Islands; ‘Moth Hunter’s Gossip’ — P. B. M.
Allen: from T. Daley; ‘A guide to the Butterflies of Central & S. Africa’
— Piney & Hoe; ‘British butterflies and their transformations’— Humphreys
& Westwood: from Rear-Admiral A. D. Torlesse; ‘British moths & their
transformations’, Vols. I & II (1854) and ‘European butterflies & moths’
— W. F. Kirby: both from Rear-Admiral A. D. Torlesse; ‘The Life of
Henry Doubleday’ — Robert Mays.

Grateful thanks are extended to donators of Journals throughout the
past year, particularly to Mr. S. N. A. Jacobs.

REPORT ON THE PROFESSOR HERING MEMORIAL RESEARCH
FUND FOR 1977-1978

Two applications were received and a sum of £50 was granted to each
applicant. They were as follows: —

(1) Dr. I. A. Watkinson, for travel incurred in connection with field
work and the study of collections for his work on the genus Phyllonorycter
for “The Moths and Butterflies of Great Britain and Ireland’, Vol. 2.

(2) The Ray Society, to help defray the high cost of publication of
Volume 2 of “British Tortricoid Moths’. Grants are not normally made for
this purpose but an exception was made in this instance because of the
importance of this work in the study of Microlepidoptera.

The sum of £100, unexpended in 1977-1978, has been added to the funds
available for grants in the current year.

EXHIBITS

Dr. A. A. ALLEN — (i) A male of Tromatobia oculatoria (F.) (Hym.,
Ichneumonidae) bred 11.viii.1978 from a cocoon found on _ heather
30.vii.78, on moorland near Dawlish, Devon. The species was most interest-
ing because it is a parasite of spiders’ nests; the larva of T. oculatoria feeds
on the spiders’ eggs. The pale ochre cocoon of the exhibit was inextricably
bound to the spider’s nest at which the larva had fed. Other closely related
species of this subfamily (the Pimplinae) have a similar life-history, and
the literature affords instances of more than one parasite cocoon being
found in a single spider’s nest.

Col. A. M. Emmet —- Two adults of Coleophora machinella (Bradley)
taken flying amongst sneezewort (Achillea ptarmica) on Ditchling Common,
Sussex, on 28.vii.1977. Larval cases of this species used to be found feeding
on sea-wormwood (Artemisia maritima) on the Essex salt-marshes from
about 1885-1903, but is was subsequently lost sight of until Dr. J. Langmaid
rediscovered it in Hampshire in 1977; there too its foodplant was sneeze-
wort.

Dr. I. WatTKINsSon — An undentified nematode, 2-3in. long, found in a
seed-tray, in Kent.
E. Wi_p — Three specimens of the Gelechiid Argolamprotes micella

(D. & S.) (determined by Rev. D. Agassiz) taken at m.v. light in S. Devon
onn 30.vii.78. This species was first noticed in Britain in the mid-sixties and
has not been taken outside Devon. Spuler gives raspberry as the foodplant.
Also a striking melanic form of Olethreutes lacunana (D. &S.) (Tortricidae)
taken at m.v. light at Dungeness 30.vi.73, determined by J. D. Bradley; not
represented in the B.M. collection.

MEMBERSHIP

The following, their names having been read for the second time, were
declared elected members: Messrs. M. S. Harvey, P. E. D. Hirst, F.R.B.A.,
and D. Corke, Ph.D.

ANNOUNCEMENTS

A. Stusps made a statement regarding the Dept. of Environment’s
recommendation that the Essex emerald moth (Euchloris smaragdaria (F.))
should be added to the listed moth or butterflies which it would be illegal
to collect. The stands of its foodplant in Essex had been reduced by sea-wall
repairs in recent years. Only one site where the moth survived was now
known. A survey of all known localities had been made and there appeared
no doubt that the moth was already for the above reasons on the verge of
extinction in Britain.

COMMUNICATIONS

Dr. A. A. ALLEN reported that Phragmatobia fuliginosa (L.) larvae had
been found at Littlehampton under dead bark of a log on the beach covered
with snow.

Dr. E. PoLLarp then gave an illustrated talk on “Monitoring the abun-
dance of butterflies’. An article covering much of this subject appears
elsewhere in this part.

After this various members exchanged accounts of their experiences
breeding progeny of recently immigrated Mythimna subg. Pseudaletia
unipuncta (Haw.), the American Wainscott. A. BRETHERTON stated he had
found the larvae strongly lucifuge. Experiments in trying to over-winter
such larvae in natural out-door conditions in Surrey had shown, after the
prolonged and severe cold spell. of recent weeks that this was impossible
in the county, though adult moths were only killed after more than ten
days of such weather.

PROC. BRIT. ENT. NAT. HIST. soc., 1979 123

8th March 1979
The President, the Rev. D. Acassiz, in the chair.

The President announced with great regret the deaths of two members: —
Douglas Ollevant, of Farnborough, Hants., who joined the Society in 1969,
and P. Lemesurier, of Kincraig, Inverness-shire, a member since 1960, both
deaths having occurred last year.

EXHIBITS

The Rev. D. Acassiz — The carcass of a pigeon, found in a church
tower and infested with the larvae probably of Endrosis sarcitrella (L.) Lep.,
Oecophoridae) and perhaps other larvae.

Dr. A. A. ALLEN — Three females and one male Zemiotes albiditarsus
(Curtis) (Hym., Braconidae), illustrating the variation within the species,
not only of the leg-colour but also of wing-venation. Until recently two
closely related species had been thought to exist:— albiditarsus, with a radial
cross-vein on the hind-wing and with off-white or white tarsi, and deceptor
(Wesmael), having no radial cross-vein and possessing testaceous-coloured
hind tarsi. The first set of characters were present in one 9, cautured
12.vi.1976 at Salfords, Surrey, while the latter set of characters occurred
in two females, one caught by day at Salfords 15.vi.1977, while the other
provided an opportunity to include a reared specimen;it was bred from a
larva of Anarta myrtilli (L.) (Lep., Noctuidae) swept from heather on
11.vili.1978 on moorland near Dawlish, Devon; the last cocoon was spun
16.viii and the parasite emerged from its cocoon, spun in that of the host,
5.ix.1978. Finally a male, one of several examples taken 9.ix.78 at m.v. light,
Kingspark Wood, Plaistow, Sussex. This form displayed the white hind tarsi
but lacked the radial cross-vein. Before obtaining the revision in the
Check List of British Insects, R.E.S. Handbook of Hymenoptera the
exhibitor had encountered some difficulty in placing this species.

Col. A. M. EMmet — Phyllonrycter viminetorum (Stainton) reared from
a mine in osier (Salix viminalis) collected at Kingsford Bridge Marsh
Nature Reserve, near Colchester, Essex, on 30th October 1978. The moth
emerged indoors on the 19th January 1979. The species, much rarer now
than it was in the last centry, has seldom been recorded in recent years.

A. J. HaALsTEAD — A second-year larva of Zeuzera pyrina (L.) the leopard
moth collected August1978 from the upper part of the trunk of Sorbus
mitchellii. The trunk diameter at this point was about 5 cm. The tree was
growing at the Royal Horticultural Society's Garden at Wisley, near
Woking, Surrey.

ANNOUNCEMENTS

The President read out a list of lepidopterous desideranda by Dr. Stig
Torstenius of Stockholm in exchange for the fine collection donated to the
Society. It was hoped members could supply most of these from their
private collections. Among species named were Lithophane leautieri
hesperica (Boursin) and Aleucis distinctata (H.-S.).

COMMUNICATIONS

Dr. A. A. ALLEN reported having found larvae of Parascotia fuliginaria
(L.) on bracket-fungi on dead pine at Hankley Common, Surrey on 23rd
February, the length of the larvae being only 6 mm.; he had also beaten on
25th February at Salfords, Surrey, larvae of Campaea margaritata (L.)
from wild privet.

C. F. Rivers reported having obtained larvae of Acherontia atropos
(L.) in Canary Is. which produced adults, of which females were eggless on
emergence from their pupae, whereas males were sexually developed and

124 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

mated immediately; six spermatophores had been found inside the bursa of
a female whose ovaries were still hardly more advanced than in the larval
state. S. KNILL-JONES reported having had a pairing of this moth in Sep-
tember. R. BRETHERTON, however, pointed out that immigrants in autumn
of other moths included females impregnated and fertile.

C. F. Rivers then gave an illustrated talk of which the following is an
abstract: —

Insect diseases and population control

“Insects are subject to infection with fungi, bacteria, rickettsia and viruses
and diseases play some part in regulating populations. In some colonies of
mosquitos virus infections are at a very low level with as few as one
diseased in every thousand collected, whilst amongst the sawflies virus
epidemics wipe out all the larvae. Wintermoths, Opheroptera, are sub-
lethally infected with Microsporida which affects the fecundity of the
species. An infestation of O. brumata in Caithness collapsed because of a
natural infection with Baculovirus (Nuclear polyhedrois) and an expensive
chemical control was called off. It is important that field entomologists
should be able to recognise when diseases are present in the population of
potential pests so that they are able to make realistic projections of the
likely pest problem. Much useful information has been gathered by the
Unit of Invertebrate Virology’s study of a virus epidemic in Gilpinia
hercyniaca in Mid Wales. Birds and mice were found to be actively assisting
the spread of the disease which brought a potentially serious pest under
control within four years. Pathogens are passed out in faeces, in meconium
and by regurgitation before the insect dies and foliage gets contaminated
heavily by dead larvae. Infection occurs as a result of ingesting pathogens
with food or, in the case of some fungi, invasion through the skin of the
insect. Diseases may be passed from adult to progeny on the surface of the
eggs and in a few instances passage within the egg has been demonstrated.
To avoid the problems of diseases amongst insects in captivity it is essential
to surface sterilize the eggs with 1% sodium hypochlorite for eight minutes
or immersion in 10% formaldehyde for 40 minutes. Careful rinsing, ventilat-
ing and drying of the eggs must follow this treatment. Wooden and
netting cages and plastic boxes used to house insects can be sterilized by
immersion in a 10% solution of Sodium hypochlorite for at least an hour.
The exclusion of sickly insects and careful breeding with vigorous individuals
is the only hope of obtaining disease free culture of insects which do not
respond to egg surface sterilization.

The observation that virus diseases very effectively control some insect
pests has led to the development of their use as pesticides and the speaker
talked about his work with Neodiprion sertifer in Scotland starting in 1958
and with Euproctis chrysorrhoea on Canvey Island. Thorough safety testing
is carried out with any virus which is a candidate for use in the field and
the Pesticide Safety Committee screens all applications to work with viruses
in Britain. At present the viruses are applied like chemical insecticides but
they lend themselves to more sophisticated methods of application, such as
spot application and the release of virus carrying adults’’.

The talk provoked an animated discussion during which P. J. BAKER
stated that a good substance to disinfect breeding cages with was Johnson’s
Baby Bottle Sterilizer which has a solution of sodium hypochlorite —
a drop of Murphy’s rose black spot fungicide should be added to the bath.

The President, the Rev. D. Acassiz, in the chair.

EXHIBITS

D. Acassiz — The first British specimen of Coleophora hydrolapathella
(Hering) (Lep., Coleophoridae), taken at Hickling, Norfolk 7th July 1974,
but only identified today. The species was added to the British list by T.
Peet from a series taken in July 1975 from the same locality.

Dr. A. A. ALLEN — A male specimen of Amblyjoppa proteus (Christ.)
(Hym., Ichneumonidae) having been bred from the pupa formed by a
mature larva of the elephant hawmoth, Deilephila elpenor (L.), by K.
Merrifield on 13.vi. 1961, subsequently passed to the exhibitor. The species
is a well-known parasite for this host, but the present specimen was of
interest because the hind-wing venation differed, the mediella of the right
hind wing being forked near the wing-markin, while this was normal in the
left hind wing. Secondly, a female example of Ichneumon bucculentus
Wesm., (Hym., Ichneumonidae) found 23.ii.1979 by uprooting a small dead
pine stump on Hankley Common, Surrey. The females of this genus spend
the winter hibernating and are sometimes encountered in rotten wood, or
under loose bark. The species is considered uncommon.

J. MuGGLETON — Two examples of the simulatrix form of Adalia
bipunctata (L.) (Col., Coccinellidae), one from Yorkshire, the other from
Somerset. These appear to be the first examples of this form recorded from
the British Isles. The Yorkshire example was sent to Mr. R. D. Pope by
Dr. W. A. Ely, and the Somerset example was sent to the exhibitor by R.
W. Rowe. The colour pattern of both the elytra and pronotum is identical
to that of Adalia decempunctata (L.) and the legs and under-side are
mostly yellow-brown as in A. J0-punctata, so that the occurrence of this
form in the British Isles seems capable of causing confusion in identifica-
tions. It is therefore important to know how common the form is in the
British Isles and the exhibitor would be grateful if coleopterists would
watch out for it. The form can be distinguished from A. 10-punctata by
the underside characters given in Pope’s R.E.S. handbook. The simulatrix
forms of bipunctata are common in parts of Central Asia, the Near East
and on some of the Mediterranean islands.

P. A. SoxoLorrF — A freshly emerged living specimen of Spargania
luctuata (D. & S.), the white-banded carpet, from a brood collected at
Ham Street, Kent, late June 1978. Despite identical treatment, about 20%
of the pupae emerged within three weeks of pupation, the remainder over-
wintering as pupae. Also freshly emerged specimens of Phyllonorcter
schreberella (F.) bred from elm leaves, West Wickham, Kent.

ANNOUNCEMENTS

The President read a letter from S. N. A.Jacobs to the effect that he was
forbidden to drive by his doctor and would be unable in future to attend
meetings. P. A. Sokoloff reported that he had recently seen Mr. Jacobs

COMMUNICATIONS

After making an announncement regarding circulation of cards, notices
and proceeding s to members, R. F. BRETHERTON reported that he had
recently suspected Lithophane leautieri hesperica Boursin of breeding in his
part of Surrey on Chamaecyparis lawsoniana a hitherto doubtful foodplant
for this moth, and had now succeded in breeding from ova laid last autumn
by this species larvae on this foodplant past the critical first instar stage;
the larvae had taken readily to the tree, first eating the male flower buds
as reported by Haggett for the larva but on Cupressus macrocarpa. They
were now growing normally and eating only the buds.

Dr. B. MacNutty then gave an illustrated talk on West African Coleop-
tera, giving the names of the majority of the Longicornes illustrated, and
information regarding the habits of some. A number of questions were
evoked by this interesting talk, and thanks were expressed in the usual way.

Thursday, 28th April, 1979
The President, Rev. D. J. L. AGassiz, in the chair.

EXHIBITS

Dr. A. A. ALLEN—Three examples of Dyspetes arrogator Heinrich
(Hym., Ichneumoninae) taken at m.v. light, Plaistow, West Sussex, 9.x.76
and 9.ix.78; there are many records of the species having been taken by
day. Also two larvae of Parascotia fuliginaria (L.) (Lep., Noctuidae) from
five such larvae found on fungi on a rotten pine log, Hankley Common,
2.ii.79. Though small when taken three had spun cocoons by 25.iv.

G. Prior — Larvae of Euplagia quadripunctaria (Poda), the Jersey tiger
moth, reared from some given to him by a member at the Annual Exhibi-
tion on 28th October, 1978.

R. Tusss drew attention to a reissue of Sepp’s plates by the firm Michael
Joseph with text by Dr. S. McNeil, under the title “Butterflies and Moths
by Christian and Jan Christian Sepp’. This originally appeared in parts in
1762 in Holland.

ARISING FROM THE MINUTES OF THE PREVIOUS MEETING

The President supplemented his remarks on his exhibit of Coleophora
hydrolapathella Hering (Lep., Coleophoridae) by saying he had received
from T. Peet a further specimn of this taken in 1974 but had failed to
identify it. He also reported having received a cheerful letter from S. N.
Jacobs.

ANNOUNCEMENTS

The President reported the Society had received, as a donation, the NCC
Survey of Esher and Oxshott Commons.

G. Prior said the library had now been reorganised on usual library
lines. Borrowed books, having been signed for, would have to be brought
back after two months but might then be re-registered to the same borrower
unless requested by another member. Overdue borrowers were being
requested by letter to return books. He suggested that where periodicals
were loose in a binder, the whole binder should be borrowed, not isolated
numbers.

R. Smices then gave an illustrated talk entitled “Charaxes the artful
butterfly; reflections on collecting in Kenya”’.

COMMUNICATIONS

Dr. A. A. ALLEN — Two females of the uncommon species Hoplismenus
bidentatus Gmelin (Hym., Ichneumonidae) were found hibernating together
11.iv.79 under bark of a pine-log on Haldon Moors, Devon. Species of the
Ichneumoninae parasite Vanessid and Satyrid butterflies. In addition he
reported that he found Stenichneumon culpator Schrank, all females,
extremely common in a few of the rotten logs. Also three larvae of
Euplagia quadripunctaria (Poda) (Jersey tiger) were taken Il.iv, 12.iv
and 18.iv.79, all at night, low on old bramble on Dawlish cliffs, Devon.
They readily ate bramble in captivity. He reported having found other
larvae at Dawlish, including Callimorpha dominula (L.) (common), and
reported other creatures observed in the same area.

R. BRETHERTON said the spring had been a good one for Archiearis
species, particularly parthenias (L.).

E. P. WILTSHIRE reported having also observed both orange underwing
species in East Berkshire recently.

A discussion of S. culpator and its reported host-specificity on Plusiinae
the ensued, in view of the large numbers found in Devon by Dr. Allen.
R. BRETHERTON mentioned that Autographa gamma (L.) had been reported
as far less numerous in Devon the previous year than usual.

The President, Rev. D. J. L. AGassiz, in the chair.

The President announced with regret the death of a member, F. C.
Brown, a resident of Surrey.

EXHIBITS

The President —(i) specimens of Thera (Lep., Geometridae) received
from Ole Karsholt in Denmark: T. obeliscata Hiibn., T. variata D. & S.
and T. albonigrata Gornik, with British specimens of Thera for compari-
son; (ii) Danish specimens of Nematopopogon panzerella (F.) agreeing
with Fabricius’ type together with British specimens which we have
regarded as that species but which Dr. Schmidt Nielsen states should be
called N. schwarziellus Zeller. In a later comment Col. Emmet stated that
whereas earlier British books gave the wrong name for the British Nema-
topogon form exhibited, the new list by Dr. Bradley had the name right.

Dr. A. A. ALLEN — (i) (on behalf of Mr. Donald Quicke, the captor), a
male example of Poecilostictus cothurnatus (Grav.) (Hym., Ichneumonidae)
taken in 1977 in the Gwernol valley, Wales, being the second known record
of the species in Britain, the first having been bred from a pupa of Bupalus
piniaria (L.) of Delamere, Cheshire. The species is well-known on the
Continent; (ii) specimens of Ichneumoninae discovered by the exhibitor in
rotten pine stumps on a moorland at Dawlish, Devon, in mid-April 1979.
Females of this species spend the winter in such habitats. The species were:
(a) Stenichneumon culpator (Schrank), a typical dark form caught on
11.iv.1979 and the much less common form in which the tibiae together
with tergites 2 and 3 were red, taken 13.iv.79. The species is a common
parasite on Plusiinae and large numbers weree taken on the moors. (b) (c)
two closely related species, Ichneumon suspiciosus Wesmael and I. septen-
trionalis atrifemur Perkins, both captured 13.iv.79. Of these the second is
less common and is liable to be confused with the first unless care is taken
in identifying (see Perkins 1960).

Col. A. M. Emmet — Coleophora adjectella H.-S. 1861, a species now
recognised as British. The first British specimen appears to have been one
reared from a case-bearing larva found mining leaves of Prunus spinosa
at Danbury, Essex, in October 1900 by W. C. Boyd during a shooting party.

128 PROC. BRIT. ENT. NAT. HIST. Soc., 1979

Itw as identified as Coleophora milvipennis Zeller by Barrett and presented
under that name as a species new to Britain (Ent. monthly mag. 38: 79-80).
That species is found in Britain on Betula and, on the Continent, also on
Alnus, Corylus, Carpinus and Myrica. Study of a recent paper by O.
Karsholt and E. S. Nielsen (Remarks on microlepidoptera new to the
Danish fauna, with a review of the Colephora milvipennis group. Ent.
Meddr. 46:1-16, Copenhagen 1978) showed that the Prunus-feeding member
of the group was a distinct species, viz. adjectella. A series of eight moths
was reared in July 1968 from Prunus-feeding larvae taken at Benfleet,
Essex on the 20th October, 1967 and misidentified as C. badiipennella
(Dup.) which was feeding commonly on the adjacent elms. These were
submitted to Dr. J. D. Bradley who determined them as C. adjectella after
dissection of the genitalia. Larval cases of C. adjectella have also been
noted at a third locality in south-east Essex and at Newtown, I.o. Wight.
The specimens from Benfleet together with examples of the four other
members of the group (C. limosipennella (Dup.), C. badiipennella (Dup.),
C. alnifolia Barasch and C. milvipennis) were exhibited; the larval cases
of all except badiipennella were also shown.

A. HALSTEAD — a leaf-mining weevil on hardy cyclamen: Orthochaetes
setiger (Beck) (Col., Curculionidae) is a small brown weevil whose larvae
feed as leaf-miners in the foliage of many wild plants particularly in the
Compositae family, such as Taraxacum, Lactuca, Hieracium, Centaurea,
and Sonchus spp. Other plants recorded as hosts are Ajuga, Myosotis, and
Plantago spp. Leaf-mining on Cyclamen hederifolium was noted on plants
growing at the Royal Horticultural Society’s Garden at Wisley, Surrey in
1975. Adults were reared the following year and identified by the British
Museum (Nat. Hist.). The weevil appears to overwinter as adults in the
soil and become active in March when the first signs of mining appear on
the leaves of C. hederifolium. The mine is initially linear but later
broadens into a blotch. The larvae go into the soil to pupate in late April-
May and adults emerge after about three weeks. By that time the foliage
of C. hederifolium is dying down, so presumably the weevils seek out one
of their other host plants.

G. Prior —a living example of Eupithecia insigniata (Hiibn.) hatched
from larvae found last year on hawthorn, as already reported, and con-
firming the identity of the larvae exhibited on 13th July, 1978.

Col. A. M. Emmet —A first-year cone of Pinus sylvestris collected in
St. Leonard’s Forest, Sussex, on the 24th November, 1978 from which a
specimen of Cydia conicolana (Heylaerts) (Lep., Tortricidae) emerged on
16th May, 1979. Before the emergence of the moth there was no outward
sign that the cone was tenanted. By a remarkable coincidence the whole
process of the moth’s emergence was observed, and the pupa-case was
exhibited protruding from the cone.

R. F. BRETHERTON— Live larvae of Lithophane leautieri hesperica
Boursin (Lep., Noctuidae) feeding on Chamaecyparis lawsoniana, from

C. SaMson then gave an illustrated account of a solo trip to Ecuador and
of the natural history of that land. He had walked, collected, and photo-
graphed, camping alone in a variety of habitats and gave particular
attention to the butterflies; however, he also showed photographs of the
condor, which, he found, was scarce, and limited to a few high mountain
habitats, also of lizards, Odonata, etc. The damp climate had corroded his
flash-apparatus within two weeks of his arrival. He carried two cameras
however so that when one broke down a reserve model was available. An
appreciative audience asked many questions at the end of the talk.

EXHIBITS

R. FarrcLouGH — Larvae of Ectropis crepuscularia (D. & S.) (Lep.,
Geometridae) from a cross between Devon and melanic Forest of Dean
moths. These were sent by Mr. M. Leech of Ross-on-Wye. A live Acleris
cristana JD. & S.) f. ruficristana Johnson. Manley in his ‘Guide to this
species (Ent. Gaz. 24, 1973) said that the whereabouts of the holotype was
unknown, and that he had been able to trace only one specimen. This
specimen, together with one other emerged from an Essex x Surrey/
Sussex pairing. Also exhibited were some moths caught 23rd January,
1979 at Ula Belait at 200 ft. in primary rain forest by Lt. Col. M. G. Allen
and sent papered to the exhibitor.

Col. A. M. Emmet — Thirteen specimens of Parornix alpicola (Wocke)
reared between the 6th and 17th of May, 1979 from larvae collected at
Eriboll, West Sutherland on the 31st of July, 1978. Sprays of the foodplant,
mountain avens (Dryas octopetala) containing larval mines and a cocoon
spun on the under surface ofa leaf were also shown and described.

The history of P. alpicola in Britain is linked with that of P. leucostola
Pelham-Clinton. Between the 5th and 8th of June, 1963 Mr. Pelham-
Clinton captured seven adults of a whitish species of Parornix at the
Invernaver Nature Reserve, on the Sutherland coast. Since leading
European authorities supported his view that they belonged to a species
new to science, Mr. Pelham-Clinton described them as such under the name
leucostola.

Early the following August, Mr. Pelham-Clinton and Dr. J. D. Bradley
visited the reserve to search for larvae on the suspected foodplant, moun-
tain avens. Numerous mines were found at Invernaver and later at Eriboll,
some 20 miles further west. In the following May, several P. leucostola
were reared from Invernaver but none from Eriboll. In addition, two P.
alpicola, a species new to the British list, were reared, one from each
locality; these emerged earlier than P. leucostola. The genitalia of the two
species were compared, continental specimens of P. alpicola being included.
No difference could be observed, except that the valva of male P. alpicola
appeared to be slightly more slender. The question whether they constituted
a single species therefore arose, but in view of the very different appearance
of the imagines and the apparent earlier emergence period of P. alpicola
they were kept as separate species and are so treated in the Kloet & Hincks
check list.

In a quest for further evidence, in 1978 Mr. Pelham-Clinton conducted
the exhibitor to the two localities and tenanted mines were collected in

PROC. BRIT. ENT. NAT. HIST. soc., 1979 131

both places. No moths emerged from Invernaver, but the thirteen P.
alpicola exhibited probably represent 100% of the larvae taken at Eriboll;
Mr. Pelham-Clinton also reared at least one P. alpicola from Eriboll. No
P. leucostola was reared from either locality, though in 1963-1964 it was
the more common species at Invernaver. On present evidence, therefore,
P. leucostola is confined to Invernaver whereas P. alpicola occurs in both
localities. Some unknown factor seems to have inhibited the emergence of
P. leucostola but not of P. alpicola. Support is therefore given to the view
that the species are distinct.

Dr. A. A. ALLEN — Three species of the genus A pantales (Hym., Braco-
nidae): A. endemus Nixon, A. limbatus Marshall and A. formosus
(Wesmael), all of which were bred from larvae of Abraxas grossulariata ee
(Lep., Geometridae) taken on blackthorn at Littlehampton, Sussex, spring
1979. A. endemus (2) was bred 29.v.1979 from a host collected 12.v.1979,
the parasite larva emerging on 17.v. This appeared to be the first record
of endemus having been bred in England; the species was hitherto recorded
from St. Andrews, Scotland and from a single French specimen (Nixon,
1965). The cocoon was remarkable for the large number of pure white
loose threads attached to the main structure. The possibility could be enter-
tained that the south coast insect represents the northern extremity of the
French record. A. limbatus (a gregarious species) was bred 4.vi.1979 (nine
specimens) from a larva collected 12.v.1979. Twelve parasite larvae emerged
from the host on 24.v.1979, from one cocoon a species of Mesochorus was
also reared; two failed to hatch. In the exhibitors experience, limbatus is
a common parasite of grossulariata, at least on the Sussex coast. A.
formosus (2°) was bred 17.v.1979 from a host larva collected 20.iv.1979.
The host was killed 8.v, on which date the parasite larva spun its unique,
stalked, pale ochre cocoon. This species is known to be bivoltine, the
second generation attacking the larvae of Lycia hirtaria (Clerck).

The exhibit formed a compact little group comprising the three known
species of Apantales known to attack, almost exclusively, A. grossulariata.
It was of interest that all three were obtained in the same year, from
larvae collected in the same locality. About 75 larvae were collected of
grossulariata: several gave limbatus, but only one each provided endemus
and formosus (the last named has an alternative overwintering host,
Ourapteryx sambucaria (L.)).

Also exhibited were five species of Lymantriidae larvae, these being
Euproctis similis (Fues.) collected v.1979 at Littlehampton, Sussex; E.
chrysorrhoea (L.) collected as first instar larvae on Birch 13.v.1979, Reigate
Heath, Surrey; Leucoma salicis (L.) taken 2.vi.1979 at Camber, Sussex, and
Lymantria monacha (L.) beaten from oak 31.v.1979 Brownsea I., Dorset.
Larvae of salicis and chrysorrhoea were abundant at Camber; several
young poplars and hawthorn/sea buckthorn hedges were almost entirely
defoliated as a result of the depredations of these larvae.

G. R. Evse — five fully grown larvae of Selenia lunularia (Hubn. (‘lunar
thorn’’). These resulted from pairings obtained from moths reared second
generation pupae received from Mr. A. Liebert. He collected the original
parent or parents at his home in Crowcombe Heathfield, near Taunton,
Somerset.

L. D. M. Packer —a female specimen of Exetastes maurus (Desvignes)
(Hym., Ichneumonidae) captured at Welling in the London Borough of
Bexley on 29.viii.1976, along with another female and male of the same
species. These three specimens constitute the 13th, 14th and 15th known

to science. The species was originally described from a specimen caught in
France. Several specimens in the British Muesum were caught at Barne-
hurst only a few miles from Welling. The host is unknown but the three
caught in Welling were flying with others around pollarded poplars and
aspens.

P. JEwess — Hypercallia citrinalis (Scop.) (Lep., Oecophoridae) one
pupa and some larvae feeding on Polygala vulgaris from Trottiscliffe Down,
Kent, 10.vi.1979.

shine 1.vi.1979, Brownsea Island, Dorset. This species is frequently illust-
trated in general entomological text books by virtue of its large size. It is
an ectoparasite of the wood wasp, its long ovipositor enabling an egg to be
laid near the host larvae as it feeds concealed in the wood. The main
feature of the parasite (which does not seem particularly common) is the
marked imbalance of the adult sex-ratios: the male is very much less
common than the female, few records exisiting for the former sex. Other
hymenoptera exhibit uneven sex ratios, the males generally being less
common. The exhibitor has, however, noted amongst the species Meso-

chrous (both captured and bred) that males are encountered more commonly
than the females.

D. W. YENDALL -— a specimen of Panorpa germanica (L.) which he had
captured, and fed on squashed sawflies.

Dr. I. McCLENAGHAN — a specimen of Aglais urticae (L.) with right fore-
wing about half normal length, but with wing pigments of same intensity as
normal. 15 others from the same broods (ex. Writtle, Essex) were normal.

K. SAMUELS — a selection of Lepidoptera taken last year in Spain, includ-
ing Macroglossum stellatarium (L.), Pyrgus cirsii (Ramb.), Pontia daplidice
(L.), Iphiclides podalirius feisthamelii (Dup.) and Pseudotergumia fidia (L.).
Also an interesting example of a halved gynandromorph of Pieris napi (L.)
bred ab ovo. Left side female, right male.

P. A. SoxoLorr — Dichomeris marginella (Fab.) (Lep.: Gelechiidae) bred
from an infested shoot of an ornamental juniper. Despite intensive spraying
of the bush with insecticide by the owner (not the exhibitor), the larval
webs had been thick enough to withstand the onslaught. Also a freshly
emerged Evergestis extimalis (Scop.) (Lep.: Pyralidae). This moth had
been reared from larvae collected Dartford Marshes, Kent, September 1978.
The larvae do not pupate until spring, and had been over-wintered outside.
Due to an oversight, the container had filled with water, which subsequently
froze solid, and the larvae had to be thawed from a block of ice. Despite
this treatment, the majority of the larvae survived and produced moths.

Membership: The following members were declared elected: Messrs. G.
G. Nobes, A. R. James and C. N. Selby.

Communications: Dr. DE Worms commented on the profusion of large
white butterflies in the South of England. Observations made on the coast
suggest that there may have been an immigration of this butterfly. Col.
EMMET reported that on the 23rd June he had captured a worn Eucosma
pauperana (Dup.) at Fleam Dyke, Cambs. This moth is normally on the
wing from mid-April to mid-May. Other members commented on the late-
ness of the season, Mr. WILD having taken Aethalura punctulata (D. & S.)
on 27th June, and Mr. Evans recently having collected ova of Hamearis
fucina (L.).

Mr. K. G. PRESTON-MAFHAM then gave a talk entitled ‘““‘The Use of
Photography in Insect Behaviour’. This was copiously illustrated with
slides of high quality, and showed many orders of insect indulging in court-
ship, mating, oviposition, emergence, predation and feeding. The wide-
Tanging and interesting talk attracted many questions from the audience.

FIELD MEETINGS

WESTBERE MARSHES, CANTERBURY — 15th July 1978
(JOINT MEETING WITH THE KENT FIELD CLUB)

Leader — T. W. HARMAN

This all day and much of the night meeting was somewhat disappointing
because of the weather which, although quite sunny by day, led to a clear
night combining with a half moon to provide a temperature down to 10°C
and even lower at ground level. This was a pity since there was an excellent
turnout of members with varied interests and many more records of this
interesting area could have been obtained in good conditions. No less than
17 members attended plus several interested friends at intervals. By night
some 10 traps were run throughout the reedbeds, in some cases there were
more entomologists round the trap than moths inside!

DENNY BOG, NEW FOREST — 29th/30th July, 1978
Leader — Cov. D. H. STERLING
In a year not noted for good collecting weather, this meeting fortunately
had about ideal conditions. The day was hot and sunny, but clouds and a
little thundery rain came up at dusk, keeping the temperature up to 17°C
for night collecting. Eight persons attended.

produced plenty of insects but nothing outstanding, although members
were pleased to note the commonness of Plebejus argus (L.) (silver-studded
blue) and Idaea muricata (Hufn.) (purple-bordered gold). Beetles found
included Micrelus ericae (Gyll.), Propylea 14-punctata (L.), Rhagonycha
fulva (Scop.).

During lunch a member’s car was dive-bombed by the water-beetle
Acilius sulcatus (L.), the shining cellulose presumably being mistaken for
water.

Afternoon collecting took place on the marshy ground adjoining the
heath. Over 500 nests of the ant Lasius flavus (F.) were noted in an area
of about two acres. On the higher heathy ground Lasius niger (L.) was
found moving about freely on the web of a Linyphid spider without produc-
ing any reaction from it, although any other slight vibration caused the
spider to rush out of its tunnel. The bird Sylvia undata (Dartford warbler)
was noted. Other insects included Pholidoptera griseoaptera (Degear) (the
dark bush-cricket), Dolichonabis limbatus (Dahl.) (the marsh damsel-bug)
and the hoverflies Eristalis tenax (L.) and Syrphus balteatus (Deg.).
Lepidoptera taken included /daea sylvestraria (Hibn.) (dotted border wave)
and Gnophos obscuratus (D. & S.) (annulet).

Evening and night collecting in Parkhill enclosure was very productive.
Catocala promissa (D. & S. ) (light crimson underwing) males were just
out and in perfect condition. Of the five seen, four were captured. Other
species of interest were:— Apoda avellana (L.) (festoon), Heterogenea
asella (D. & S.) (triangle), Ptycholomoides aeriferanus (H.-S.), Lozotaen-
ioides formosanus (Gey.), Epagoge grotiana (F.), Idaea straminata (plain
wave), Boarmia roboraria (D. & S.) (great oak beauty), Meganola strigula
(D. & S.) (small black arches), A pamea scolopacina (Esp.) (slender brindle),
and Eustrotia uncula (Clerck) (silver hook). Beetles included Necrodes
littoralis (L.), Melanotus rufipes (Herbst.), Aphodius rufipes (L.), Serica
brunnea (L.), Limonius minutus (L.), Gyrinus substiatus (Steph.), Carabus
violaceus (L.), and Chrysolina graminis (L.). Other insects included the
ubiquitous Vespa crabo (L.), Ectobius lapponicus (L.) (dusky cockroach),
the shield-bug Pentatoma rufipes (L.) and the water-bug Callicorixa praeusta
(Fieber).

In all, 190 different species of lepidoptera, 16 of coleoptera, 3 ants and 9
order were recorded. A full list was sent to the Deputy Surveyor, New
Forest, but is too long for reproduction here.

TROTTISCLIFFE, KENT — 12th August 1978

Leader — K. G. W. Evans

Despite the promise of inclement weather, 12 members attended this
joint meeting with The Croydon Natural History and Scientific Society.
With the kind permission of the Kent County Council, Trossley offers the
entomologist a fine collecting area over a wide expanse of chalk downland
surmounted by a considerable tract of deciduous woodland. Early rain
precluded much of the hoped for field work but a few specimens of The
Straw Belle, Aspitates gilvaria D. & S. were kicked up and much time was
devoted to renewing old friendships and exchanging helpful information.
Despite the bad conditions many insects were identified and in the evening
ten lights were established as well as quantities of sugar. While the latter
proved a wasted effort, the lights attracted a good volume of insects but
little that was not expected.

EPPING FOREST, ESSEX — 29th October 1978
Leader — A. M. EMMET

The year 1978 marks the centenary of the Epping Forest Act, which
conserved the Forest for the nation. The occasion was marked in May by a
symposium at which papers were read on its flora, fauna and history. In
preparing a list of the Lepidoptera of Epping Forest for the symposium, the
author found that many common species of microlepidoptera, though
doubtless present, had never been recorded. One of the purposes of the
field meeting was to fill these gaps.

An exceptionally bright and warm day for late October attracted an
attendance of at least 28 members and their families. The sunshine brought
comma and peacock butterflies on the wing and there was a distant sighting
of a female brimstone or one of the whites. After assembling and having
coffee at the Epping Forest Conservation Centre, the party moved off to the
relatively open ground of Whitehouse Plain, where a total of 79 species of
microlepidoptera were identified; to these a further six may be added
which were observed in adjacent areas during a reconnaissance earlier in
the month. Out of these, 36 had not been recorded previously and these
additions bring the number of Lepidoptera found in Epping Forest to over
1,000.

Potentially the most interesting record was of Stigmella carpinella
(Heinemann), but this requires confirmation. This hornbeam-feeding species
was added to the British list as recently as 1976 and was recorded in
Hainault Forest, Essex in 1977. Two or three mines only were found, one
of which was still tenanted. It is hard to distinguish the mine from that of
S. floslactella (Haworth), a very common species but not recorded from
Epping since its principal foodplant, hazel, is absent. It also feeds on horn-
beam, but is always abundant where it is found, like the other nepticulid on
the same foodplants, S. microtheriella (Haworth), which is plentiful at
Epping. Hence, somewhat paradoxically, the scarcity of these mines at
Epping makes it probable that they belong to the rarer species.

Another very local species was Tischeria angusticollella (Duponchel),
whose mines were found on wild rose. Vacated mines of Stigmella
distinguenda (Heinemann) were noted on birch and of Etainia sphendamni
(Hering) in the keys of field maple. The Faircloughs worked the blackthorn
thickets for Acleris cristana ({Denis & Schiffermiiller]) and obtained over
20 specimens covering a range of forms, none rare but some very beautiful.
These were retained for breeding.

A complete list of the species observed has been sent to the Epping
Forest Conservation Centre as an appendix to the list already lodged there.

A recorder’s log-book or label-list of British Butterflies and Moths, by J. D.

Bradley and D. S. Fisher. Curwen Books, 1979. Price £2.00

This pocket-sized paperback check-list is a novel production: the first
column on each page consists of the names of the species and subspecies,
the second column being left blank for the user to insert further data
against those forms he may observe. If used in recording for the Biological
Records Centre, the latter, after registering the records, will return the log-
book to the owner. Previously, recorders used cards for this purpose. If
they wish to continue to use it for the same purpose it would see that
their entries should be in pencil!

By and large, the list is the Kloet and Hincks 1972 check-list omitting
most of the synonyms. The very first species on the list appears now as
Micropterix tunbergella Fabr. (with thunbergella auctorum as a synonym).
The two authors have chosen to omit the parentheses round the names of
all authors; these were inserted in the 1972 check-list in accordance with
correct zoological nomenclature rules but in the work under review their
omission conforms with the rather general practice of lepidopterists, which
our present editorial policy has endeavoured to correct. The omission of
the “th” in the specific name quoted above raises the vexed question of
whether one should adhere to the original and earliest spelling of a name
even when it may be an obvious error (elsewhere in the list the authors
insert an “th”? when printing Thunberg’s name! )

In another place, the generic name Helicoverpa Hardwick 1965 is retained
for the scarce bordered straw, although Hardwick 1970 and Todd 1978
reincluded Helicoverpa (and other generic names) in Heliothis, apparently
sinking it to subgeneric status or even synonym!

The difficulty of bringing the nomenclature of a long list ‘up to date”
as the publishers claim has been done, is demonstrated by the above random
examples, and the question of which check-list our readers should follow is
once more raised. On the whole we think most will like to use this list,
and for recording and registering questions of nomenclature are, at the
most, a problem for the staff of the Records Centre.

A Dipterist’s Handbook. Edited by Alan Stubbs and Peter Chandler. The
Amateur Entomologist, 15, ix + 255 pp., many figs. 1978. Price £6.00
This is an excellent book, following the high standard set by the

Amateur Entomological Society with their handbooks on the Lepidoptera,
Coleoptera and Hymenoptera. The editors are two of this country’s most
energetic Dipterists, with a wide experience of fieldwork and an apprecia-
tion of the endless diversity and versatility of the Diptera. They have
enlisted the help of a large number of fellow-Dipterists to contribute
sections on their specialities—indeed, the list of contributors reads almost
like a check list of British Dipterists.

The key-notes of the book are enthusiasm and comprehensiveness. There
can be few Dipterists browsing through this book during winter evenings
who will not be fired with the desire to get into the field again. During the
summer months it will prove an invaluable vade mecum for tyro and
pundit alike, since it contains detailed results and summaries alongside

PROC. BRIT. ENT. NAT. HIST. SOc., 1979 139

suggestions for further lines of enquiry. One of the attractive features of
the book is that several contributors have given complete synopses of their
subjects, though for reasons of economy these have had to be presented in
cursive rather than tabular form and are more difficult to use. It is always
invidious to single out examples of particular excellence, but it seems to
me that the sections on associations with fungi, the higher plants and
dung are outstandingly useful contributions. The key to families of Diptera
larvae, containing a wealth of illustrations, fills a longstanding lacuna in
the literature and it is worth buying the book for this alone. I welcomed
too the deft touches of humour provided by one well-known contributor.
The book has been produced at high speed, and this is reflected in a
4-page errata slip accompanying it. Needless to say, this includes nowhere
near the full number of misprints, but all slips of this kind can be corrected
in a second printing and hardly detract from the quality of the work itself.
In short, a fine book: a must for all Dipterists and indeed for most
entomological fieldworkers.

OUR CONTEMPORARIES

Environmental entomology, Ent. Soc. Amercia, 7 (1), 1978

There are thirty-six articles in this fascicle of Vol. 7 of this magazine, and
we select two as of general interest: — T. C. BAKER and R. T. CARDE:
Disruption of Gypsy moth male sex pheromone behaviour by high frequency
sound.

Males of the day-flying moth Lymantria dispar (L.) while flying up-wind
towards a pheromone source respond to high frequency (> 15 KHz)
sounds by deviating sharply from the established flight-course and flying
away rapidly. Pheromone-stimulated males fanning their wings while
walking on the substrate, ‘freeze’? momentarily in response to high
frequency sound. The puncturing of both tympana eliminates auditory
behaviour, whereas perforation of only one tympanum causes highly
direction flight course deviations towards the perforated (silent) side. The
retention of ultrasonic sensitivity in this essentially day-flying species may
be explained by the selective advantage from bat predation gained by
individuals near dusk. (Females of this species had less well developed
tympanic organs than males.) Response to 2 pheromone in these males is
wing-fanning before flight. These observations were made in a wind-tunnel.
“Freezing” (a cessation of activity) lasted ten seconds. The two tympanic
membranes of L. dispar are located in a smooth sclerotized channel on the
postero-lateral margin of the metathorax. They are directed obliquely
posteriorly towards hair-covered counter-tympanic hoods on the first abdomi-
nal somite which cover all but the extreme lateral edges of the scaleless
channels. A sensillum similar to that described for Agrotis ipsion (L.)
appears to be attached to each membrane in the centre and to extend
internally into the tympanic air-sac. In the experiments the membranes
were ruptured with a pin after retracting the hoods, and this is claimed to
have inhibited response to high frequency signals. However, the same sound
did have some effect on females despite their less sensitive ears. But lower-
key sounds had no effect on these flying males.

These species are well known pests in the Mediterranean and Middle
East and the purpose of the experiments was to select “candidate chemicals”
for “inhibition and disruption of inter sexual communication in these
species”. Both these articles shed light on the ability of female lepidoptera
to attract males and the methods evolved by moths to escape bat predation;
the former is of course assumed to be by chemical means, while a different
organ is involved in detecting the ultrasonic radar-emissions of bats which

help those predators to spot moths in flight, and in evading the bats’

attacks.

There is much interesting matter in the last part of Vol. 32 of this well-

Harry K. CLencu (pp. 277-281): The names of certain holarctic hair-
streak genera. The author picks up the article by Malicky in the publication
of the Bale Entomological Society of 1969 which, mainly dealing with early
stages and breeding of European Lycaenidae, also contained taxonomic
proposals, one being the recognition of the generic difference between the
Black and the White-letter hair-streak butterflies and certain other non-
British hair-streaks such as spini (D. & S.), ilicis (Esp.) and acaciae (F.).
For pruni (L.) Malicky therefore substituted Fixsenia Tutt 1908, retaining
Strymonidia for the others. Clench however argues that Satyrium Scudder
1876 is more correct for the four others mentioned. As our compilers of the
revised Kloet and Hincks 1972 check-list apparently overlooked Malicky’s
proposal, perhaps they would now consider the matter again particularly
in view of Clench’s following Malicky in one particular and superseding
him in another.

Another article deserving mention here, as of general interest, is the
short note by RAYMOND W. NEcK (pp. 310-311): Additional function of the
Lepidopteran proboscis. The author has observed the adult in certain cases
to use its coiled tongue for preening and removing water from its vestiture.

The Society’s Publications

ILLUSTRATED PAPERS ON BRITISH MICROLEPIDOPTERA

Still available, a small number of copies of the recently published volume
of twelve articles reprinted from the “South London’”’ Proceedings between
1944 and 1957 with the twelve original colour plates.

These papers comprise LAMPRONIIDAE and ADELIDAE, LITHO-
COLLETIS and OECOPHORIDAE (three parts) and ALLIED FAMILIES
by S. N. A. Jacobs; PSYCHIDAE, PLUTELLIDAE and GLYPHIP-
TERYGIDAE and ALLIED GENERA by L. T. Ford; CALOPTILIA and
LYONETIIDAE by S. C. S. Brown; ERIOCRANIIDAE and MICROP-
TERYGIDAE by J. Heath and MOMPHA by S. Wakely. For ease of use
the pages and plates have been renumbered and are fully indexed
-accordingly; in addition there is a new appendix drawing attention to
species belonging to these groups which have been added or sunk. There
is also a list of species which relates names used in the text to up-to-date
nomenclature and classification.

A limited edition of 500 copies was published in the Autumn of 1978,
bound in cloth, price £9; £6 to Members of the Society. Postage, where
applicable, 60p extra. Cheques should be sent to R. F. Bretherton, Esq.,
c.B., Folly Hill, Birtley Green, Bramley, Surrey.

A FIELD GUIDE TO THE
SMALLER BRITISH LEPIDOPTERA

The Society also announces the publication, probably in late summer
this year, of the above important and entirely new work, bringing up to
date and uniting the well-known Guide by the late L. T. Ford, B.a., and
the Supplement, both hitherto advertised on this page, with much additional
matter. Bound in stiff paper cover. Price and procedure for purchase, same
as for above “Illustrated Papers”’.

A LEPIDOPTERIST’S HANDBOOK

The Amateur Entomologist’s Society is pleased to announce the publication
of its latest Handbook, written by Richard Dickson. It is intended as a
‘vade mecum’ for both beginners and initiated lepidopterists and deals with
all aspects of the subject in a series of eleven chapters and four appendices.
There are 34 line illustrations and 13 photographs to augment the text and
the binding has been sewen to meet constant use.

It is apractical book on the various facets of breeding, collecting, storing,
conservation and photography of lepidoptera and should appeal to most
