EDITORIAL
The advisability of breeding Lepi-
doptera for release has recently
become a topic of discussion in the
Bulletin. The Members who consider-
ed that such releases prior to full
studies and without proper control
were harmful, were further dis-
quieted by the existence of the AES
Breeding Group—which had the
general aim of rearing butterflies for
release.
The AES Council have had in mind
the necessity of conservation of our
insects and their habitats, and there
has now been derived an Amateur
Conservation Group within the
Society. The Breeding Group has
ceased to exist, any activities in this
direction being incorporated into the
much broader-based Conservation
Group, the aims of which are set out
in an article in the following pages by
the convener of the new group, Mr
K. J. Willmott.
The Council is able to give its full
support to the new group, which will
cooperate with the various existing
local and national bodies for nature
conservation but—unlike most of
them—exists as representative of
entomologists. There is certainly a
need in the AES for such a coordinat-
ing group concerned with conser-
vation, and it is to be hoped that
Members will give it their fullest
support. There is a very great deal to
be done along the lines indicated by
Mr Willmott—and this requires that
as many Members as possible share in
the activities of the new group.

Acleris variegana Schiff. Mr E. S.
Bradford drew the lower specimen
some years ago and, forgetting that
he had done so, drew the upper one
last winter. As the two portraits
represent different forms of the same
species, | thought it would be of
interest to show them together. Mr
Bradford wrote two sets of notes to
accompany the drawings; these | have
amalgamated, as far as possible retain-
ing his original words.
“This, as its name suggests, is a
variable species. The upper drawing
is from a fairly normal specimen bred
from Hawthorn (Crataegus sp.),
while the lower is from another bred
from a rambler rose (Rosa sp.) in the
garden. The larva also feeds on
Blackthorn (Prunus spinosa Linn.); it
folds a leaf of its foodplant or spins
two leaves together.

purplish black with reddish scales.
The form illustrated in the lower

feature common to nearly all speci-
mens is the orange-brown cilia at

specimens one can see tufts of scales
sticking up all over the wings; hence
the old or common name, the ‘Rough-
winged Button’. The hindwings are
a pale greyish brown and in most
specimens there are darker markings
like a mosaic or tracery. The adult is
on the wing from July till Septem-
ber.”’

AES BULLETIN, VOL. 27
the war recently became one of the
writers of the Official History of the
Second World War. Before accepting
his invitation, he asked for whom he
would be writing—staff-college
students, those who took part,
foreigners assessing the British image,
the general public or posterity. It
makes so much difference to what
you say and how you say it. He
received no very satisfactory answer:
he would be writing for them all. If |
asked the Editor a similar question, |
would expect an equally evasive reply,
for what could he say? Now in this
article | have decided to write for a
very limited class of reader—for the
collector of ‘Macros’ who is attracted
to the ‘Micros’, but is fearful of taking
the plunge. | am going to suggest to
him fifteen common species, the
larvae of which he can readily find in
most parts of the country before the
next issue of the Bulletin appears. Let
him search for them, rear them, and
throw away his ‘L’ plates. So the
hoary old campaigner should turn the
page and go straight on to the
Hymenoptera Aculeata.
| have selected three species of the
Tortricidae. Epinotia tedella Clerck
feeds on the needles of Spruce (Picea
abies (Linn.) Karst), spinning them
together and blanching them; fresh
feeding is of a greenish white colour.
Collect at the end of February.
Endothenia gentianaeana Huebn. feeds
on the pith in the heart of the heads
of teasel (Dipsacus spp.). The larvae
are full-fed in the autumn, but do not
-pupate until the spring: gather them
at any time. If you put on stout gloves
and rip open thistle (Carduus spp.)
stems, you will probably soon locate
the pinkish larva of Epiblema scutulana
Schiff. If you wait until April, you
should also find pupae.
_ From the Gelechiidae | have chosen
Caryocolum tricolorellum Haw. During
‘late February or early March, collect
the spun tender shoots of the Greater
‘Stitchwort (Stellaria holostea Linn.)—
|
a plant which is common under most
hedgerows.
| have selected the largest of the
Cosmopterygidae, namely Limnoecia
phragmitella Staint; the larvae are
found in the shaggy heads of bulrushes
(Typha spp.). Among the Oecophori-
dae is Dasycera sulphurella Fab. lf you
prise off the loose bark from the
dead stumps of oak or other trees (or
even from fallen branches), you
should soon come across its whitish
larva—and, possibly, other more
exciting species. You should wait
until April for my Glyphipterygid:
then almost any patch of nettles
(Urtica dioica Linn.) will yield loosely
spun leaves containing larvae of
Simaethis fabriciana Linn.
Here are three suggestions for the
Hyponomeutidae. The needles of
Pine (Pinus sylvestris Linn.) are mined
in March and April by the larvae of
Cedistis farinatella Dup. If you pick
the catkins of birch (Betula spp.) in
April, concentrating on those which
are distorted, you should get larvae
of Argyresthia goedartella Linn. and
the more beautiful but slightly less
common A. brockeella Huebn.
It is rather early for the Coleophor-
idae, but you should be able to find
Coleophora gryphipennella Bouch. on
rose shoots by the middle of April.
Look out for the characteristic
‘windows’ in the leaves, with the
neat, round hole in the lower
cuticle.
You should readily be able to find
three species of Lithocolletis. Search
Beech saplings (Fagus sylvatica Linn.)
which have retained their leaves and
you will almost certainly find the
mine of L. faginella Zell. on the
underside; you can start collecting
them right away. You should, how-
ever, wait longer for the other two
species. These are L. messaniella Zell.
in Holm Oak (Quercus ilex Linn.)—
passim—and L. trifasciella Haw. in the
young leaves of Honeysuckle (Lonicera
periclymenum Linn.); by mid-April, if
4
you search in woods, you should start
finding the inflated, twisted and often
discoloured leaves containing the
larvae of the latter species.
From the Lyonetiidae | have picked
Tischeria| marginea Haw., which
puckers the leaves of the evergreen
bramble (Rubus fruticosus agg., part)
with rather a pear-shaped mine. The
larvae commence feeding in the
autumn and complete their growth
in the spring; so the leaves may be
located in the early months of the
year, but should not be picked until
April. Much the same applies to
Nepticula aurella Staint.—my final
selection—which also hibernates in
its mine and the long galleries of
which are conspicuous in the leaves
of the same foodplant; but these
larvae ieave their mine to pupate and,
if it is a mild spring, they will be
gone early in the month.
If you get all fifteen of these species,
you are doing well. Just to see if you
are on your toes and to make it a
little easier, | have, in fact, given you
sixteen! And you experts, if against
my advice you are still with me,
what different selection would you
have proffered to a_ hypothetical
beginner, bearing in mind that we
should try to represent most of the
families?

Now is the time for taking stock of
past seasons and looking forward to,
and planning for, the future. One
topic | have had in mind relates to
ants, and in particular to the marriage
flights of the common species of
Lasius, L. niger Linn. and L. flavus Fab.
Both these species are abundant and
widespread and have important influ-
ences on the ecological processes of
our countryside. The winged forms
emerge in summer, sometimes as
early as July, but more usually in
‘headed Gull, Larus ridibundus Linn.|

some years. Nests of these species’
are founded by single fertilised |)
queens. These, therefore, have to}!
carry within themselves on their|)
marriage flights sufficient nutrients)
to support themselves for the period
until the following spring and also to) “|
allow the first few workers to be)
reared. The production each year of)
large numbers of these winged queens |
obviously injects into the environ-|
ment an important food source, and
many predators take advantage of):
this, the best known being birds. 10)
The particular feature that has)
interested me is the habit of gulls in|
circling to take these flying ants in the
air. The only species | have definitely
identified doing this is the Black-j)\

have also seen the same behaviour on}
the Belgian coast at Westende (I Ithiy.
August 1965 and 22nd August 1967)./9)
Indeed | now find that the behaviou
of the gulls in an area is a ver
sensitive indicator of the occurrence},
"AES BULLETIN, VOL. 27
and extent of an ant flight.
The behaviour of the gulls in such
‘lights is very characteristic. The
ndividual birds fly slowly round,
‘liding interspersed with rather rapid
ving beats noticeably fast for the
actual speed of flight. During this
tircling catching movements are
nade, either of the head only or of
“he whole body as the culmination of
series of rapid wing beats. The flocks
-eem rarely to be of less than twenty
or thirty birds, and often more than
00 are involved, circling up to 200
300 ft. More rarely some birds will
swoop down below tree-top height,
vay 30-50 ft.
_ Two points interest me. First, how
song established and how widespread
+s the habit, and can the occurrence
if flocks be used to follow the area
ssver which ant flights are synchro-
viised? As to the first point, the Black-
‘ieaded Gull is a species which has
)narkedly changed its habits during
Dhis century, changing from a coastal
| ird to one that feeds widely over the
) ountryside. The change of behaviour
hat enabled this to occur proved a
‘very successful one for the species,
‘ind perhaps the present case is
nother example. Tne species has
| pcapted its normal circling behaviour,
n thermals and up-currents by the
| Pe to the taking of flying ants which
jormally occur under conditions of
hermal activity.
/ On both points | now appeal to my
veaders. If AES Members would make
) point during the coming season of
)vatching for the behaviour | have
Jescribed and if they do see it make
_ note of the place, date, species of
cull, and whether or not the presence
flying ants was confirmed, a picture
J vould quickly build up of the present
jistribution of the habit. It would
‘Iso be apparent to what extent
| bservations of this sort would form
| convenient way of studying the
()ynchronising of the marriage flight
fants over wide areas. | look forward
to hearing from Members at the end
of the season.

Coleoptera (by J. Cooter)
My notes have been compiled from
the list of Coleoptera collected by
my father during May 1965 and June
1966 when he was on holiday as a
volunteer warden at the Loch Garten
Bird Reserve near Nethy Bridge,
Inverness-shire. Mr J. K. Smith kindly
sent mea list of the rarer species that
he collected in September 1966 at
Loch Garten. Many of the beetles
are not true Scottish species and
quite a few are widespread occurring
in most parts of the British Isles.
(The collecting season—when the
coleopterist stops using collecting
methods he has been using in the
winter—begins about a month after
it does in the south of England, i.e.,
the end of May.)
My father found that the best
collecting method to use in early
spring was to pull up handfuls of wet
feathery moss, squeeze it gently to
get rid of any excess water, then
shake the moss over a white sheet,
or old plastic table cloth—as my
father used. Any large beetle can
then be captured and put into a tube,
whereas the small fry can be collected
with a pooter as they run across the
cloth. While in Scotland in June, my
father found moss to be unproductive
and other methods of capture had to
be employed.
Most of the beetles found in the
moss belonged to the Adephaga,
[os
although large numbers of Staphy-
linids were also present. Several rare
and local species were collected,
namely a short series of the rare
Agonum scitulum Dej. and a single
example of the pretty A. ericeti Panz.
Several ‘northern species’ such as
Nebria gyllenhali Schoenherr and the
var. balbii Bonelli were taken. Tricho-
cellus cognatus Gyll. and Patrobus
atrorufus Stroem were not too com-
mon. P. atrorufus, a moorland species,
is more common in the north than in
the south. It does occur in the south,
however, and | have captured a
specimen near Brockenhurst in the
New Forest, Hampshire. Perhaps the
most common beetles in the moss
and elsewhere were three species of
Calathus, namely C. melanocephalus
Linn. var. nubigena Hal., C. micro-
pterus Dufts. and C. piceus Marsh.
Other species of the Carabids include
Pterosticus oblongopunctata Fab. P.
diligens Sturm and several smaller
beetles which | still have to name.
Among the Staphylinidae were lots
of common species and only a few
rarities from moss; a specimen of
Atheta (Liogluta) hypnorum Kw. and
two uncommon _ ‘staphs’—Atheta
(Metaxya) arctica Thoms. and A.
(Hypatheta) aquatica Thoms. Two
specimens of the large Staphylinus
erythrepterus Linn. were captured in
mid-June under stones at the side of
Loch Garten. One example of Ocypus
brunnipes Fab. was taken while my
father was taking the bark off a dead
birch (Betula) tog. | have only found
this beetle hibernating under bark.
This may be only coincidence. Some
of the more common ‘staphs’ were
Quedius molochinus Grav., Q. fuligon-
osus Grav., Philonthus marginatus
Stroem, P. politus Linn. (=aeneus
Rossi), Lathrobium elongatum Linn.,
Stenus impressus Germ., Anthobium
unicolor Marsh (from fungus), and
several very small species probably
from the genus Atheta and related
genera. Three specimens of Xantho-
FEBRUARY, 1968
linus tricolor Fab. from Glenmore)”
were captured under stones. Mr Last
informs me that this species is found
more in Scotland than in England.
By luck my father captured an
example of the large Carabus glabra-
tus Payk. var. lapponicus Born at the
edge of a road running through the
Abernethy Forest where he also took
a specimen of Cicindela campestris
Linn., a beetle usually found in the
south or coastal districts in the north
and midlands, on sandy heaths or
sand dunes. This particular specimen
was found in a peaty region. In early
May the Hydradephaga and aquatic
Palpicornia can be easily netted.
Several specimens of Agabus sturmii
Gyll. and A. bipustulatus Linn. as well
as a single specimen of Ilybius fuligino-
sus Fab. were captured. Unfortu-
nately, they can be taken in almost
every other pond in the United
Kingdom! Smaller members of the
family (probably Hydroporus) were
also captured, as were a few un-
interesting aquatic Palpicornia.
Only two species of Chrysomelidae
were captured. One copper-red
specimen of Plateumaris discolor Panz.
was found in moss at the loch side.
Sweeping the reeds later in June
failed to produce any more of this
species or any more of the aquatic
Chrysomelidae. Lochmaeda suturalis
Thoms., a very common insect in
nearly all parts of the country, was
abundant in mid-June on the heather.
To my pleasure, two northern
species of Cerambycidae were cap-
tured by my father. One specimen o
Pogonocherus fasciculatus Deg. appear-
ed in the water net. This beetle is
found in the south-east midlands
(Lincolnshire?) but is believed to
have been imported from the north.
Three examples of Rhagium inquisitor
Linn. were found early in the morning
on freshly cut fir palings in the
Abernethy Forest. Mr J. K. Smith
found several of this species near
Loch Garten. Rhagium bifasciatum
) AES BULLETIN, VOL. 27
Fab. was also found. Some larvae
brought home by my father proved
| to be R. bifasciatum. Only two species
of Curculionidae were collected,
these being Hylobius abietis Linn.,
| presumed to bea pest in some forests,
| the other being the rare Eremotes ater
/ Linn., a northern insect. Although
| listed by Joy (1932) as being rare, my
| father has collected a series of this
| beetle each time he has been in
) Scotland. (He told me that he didn’t
| take too many of them because he
|) found it so commonly and thought
| that | must have caught it myself!) It
| can be found on decaying trees or
| stumps in the Abernethy and Rothie-
murchus Forests.
A very good find was Dictyopterus
| aurora Herbst. Several of this species
| were found in a rotten tree stump in
| the Rothiemurchus Forest. This is a
‘truly northern beetle, being found
/ only in parts of Scotland.
* Mr Smith found a single example of
| the rare and beautiful Pytno depressus
Linn. under the bark of a Scots Pine
/ log (Pinus sylvestris Linn.). Another
Scottish beetle, it is found in North
|) West areas of Scotland extending
- south to Aviemore.
Geotrupes stercorosus Scriba was
| fairly common in the Abernethy
| Forest and was the only large member
|| of the Scarabaeoidea noted. The true
i) northern Aphodius beetles were fairly
; common—A. nemoralis Erichson was
;, to be found in deer or sheep drop-
| nemoralis is rare and found in deer
() droppings in Scotland.) Aphodius
| lapponum Gyll. was not as common as
| | expected. Britton states that A.

y Or deer droppings. Other dung
y beetles include Aphodius ater Deg.,
A. depressus Kugelann, A. rufipes Linn.,
(| A. fimetarius Linn., and A. aestivalis
y Steph. A single specimen of Serica
» brunnea Linn. was bred from a pupa
found in the Abernethy Forest.
Several specimens of Thanatophilus
rugosus Linn. were found in carrion
and in carcases. One example of
Oeceoptoma thoracicum Linn. was
found in a rotten Swede (Brassica
napus Linn.) and several others were
under pieces of wood, etc. Only one
example of the handsome Aclypea
(=Blitophaga) opaca Linn. was cap-
tured. Mr Smith found five specimens
of Dendrophagus crenatus Payk. near
Loch Garten.
| would like to thank Mr D. Tozer,
Mr H. Last, Mr J. Balfour-Browne,
and Mr R. Adams for identifying
some of the insects that were
collected, Mr J. K. Smith for supplying
a list of the Coleoptera that he
captured in Scotland and my father
for collecting so many beetles for me
in his spare time.
Trichoptera (by Brian Morrison)
During the past year, practically
all my observations have been con-
fined to a stretch of the Union Canal
which lies on the boundary of
Edinburgh and over which crosses
the road (A70) to Mid-Calder. |
decided | would try to record the
times at which the various species
could be found in the adult state in
this rather restricted area rather
than go on hunting expeditions far
and wide over the countryside.
With regard to the Canal itself,
there is very little to say. The bottom
is muddy with a dense population of
water weeds of various sorts, particu-
larly Fontinalis, Elodea (Anacharis)
canadensis Michx. (Canadian Pond-
weed) and near the banks there is a
profuse growth of Potamogeton sp. in
some areas. The surface of the water,
particularly in summer, becomes
covered with a mat of duckweed
(Lemna sp.). The fauna is very rich in
still-water species and caddis larvae
are particularly numerous. The
accompanying table (Table 3) gives
the results of my researches on adult

emergence but | am certain that
there are several other species
present judging from the types of
larval cases found.
Instead of giving a long discourse
on the subject | would just like to
mention one or two points which
might be of interest and which | feel
are worthy of further investigation.
As | mentioned earlier, part of the
Canal runs under a road bridge and
in the course of the season | made a
number of visits to the bridge to
look for insects which might be
resting on the underside of it. | was
able to examine parts of it from the
towpath which was about six feet
broad.
The large Phryganeids (Agrypnia
pagetana Curtis) were found almost
always hidden in the crevices in the
stonework rather than on the surface.
Anabolia nervosa Curtis and Chaetop-
teryx villosa Fab. were only very
rarely found under the bridge, but in
season were extremely common on
grasses and other plants growing on
the Canal banks. Limnephilus lunatus
Curtis and L. flavicornis Fab. were

very common both under the bridge)
(not usually in crevices) and on
vegetation on the canal bank and at
the edge of the towpath. 4
Leptocerus spp. were found most) |
commonly at a position resting on the)
side wall of the towpath, very often! |
near empty pupae, and also flying very,
close to the bank, rarely straying far|
from the water. Limnephilus spp. on)
the other hand were never found at
the towpath edge under the bridge |
and were quite commonly found 100°
to 200 yards away from the canal on)
fence posts by the roadside. |
One point of interest is that
around the fifth of July | discovered
several larvae at the edge of the
towpath next to the arch of the °
bridge. | am not sure what specie
they were but | am fairly certain that
they were Limnephilids. The fact that -
| subsequently found empty pupal —
cases and Limnephilids with not fully |
expanded wings on the arch of th
bridge just above the towpath make
me feel more certain about this. Ii
this is so, it seems that these larva
emerge from the water when full

grown and pupate on land. This has
still to be verified. | have not come
across any other such accounts of
this behaviour.
It will be seen from the table that
L. lunatus is to be found right through
December. Specimens dissected at
that late date were found to be full of
eggs. During the recent Xllth Ento-
mological Congress in London, a
paper was submitted in which it was
stated that many Limnephilids which
inhabit bodies of water which are
seasonal in times of appearance, i.e.,
late summer and autumn, actually
emerge in spring but remain in
hiding until later in the year when
they can lay their eggs in the newly
formed pools. This makes me wonder
whether Limnephilids might hiber-
nate in certain circumstances. | am
told this is very unlikely, but | hope
to investigate the matter further. It
seems to me interesting too that
adults with eggs can be found as late
as December.
lfany Member is keen on taxonomy
then the Trichoptera offer ample
scope. Work has been done on the
genus Limnephilus (and one or two
other genera), and on the Leptoceri-
dae, in more recent times, but a lot
remains to be done. The trouble with
the key in Mosely (1939), which is
still the standard work, is that the
diagrams are not always reliable and
it is often impossible to determine
single specimens if they are female.
The following is a list of species
taken in the area discussed:
Agrypnia pagetana Curtis, Lepto-

THE AIMS OF THE AMATEUR
CONSERVATION GROUP
|. The present AES Breeding Group
will no longer exist, but will become
a part of this new AES group and will
10
FEBRUARY, 1968
have an entirely new constitution.
2. The main aims of the Amateur
Conservation Group are as follows :—
—To assist and cooperate with
county and local conservation
groups in order to interest them
in, and advise them on, the con-
servation of insect fauna and suit-
able areas which should be given
special attention.
—To collect and collate information
on local insects and the status of
the insects and their habitats for
use when such insects or areas are
in danger.
—To breed and supply insects for
nature reserves and special areas
where it has been agreed with
other interested groups that this
is desirable.
—To supply an annual report to the
Society on the conservation activi-
ties of the group and to encourage
all Members to be active in this
field.
3. As regards the collection and
collation of information as mentioned
above, it is suggested that the group
should undertake studies of various
species, not only the rare and local
species but also those termed un-
common. Such suggested studies
include work on the Glanville Fritill-
ary (Melitaea cinxia Linn.) on the Isle
of Wight; the Heath Fritillary
(Melitaea athalia Rott.); the Purple
Emperor (Apatura iris Linn.); and the
Adonis Blue (Lysandra _ bellargus
Rott.). These four species, along with
others, need careful conservation
studies within the next couple of
years, and it would be wise to note
details such as population numbers;
distribution; rearing in captivity for
possible release; distribution of food-
plant and its conservation; and advice
for future conservation efforts.
4. \|f any Members could undertake
other detailed work on_ species
needing such a study, would they
please contact the group convener as
soon as possible giving details.
5. The possible breeding and supply
of insects for release relates to the
late Breeding Group. Members would
rear Lepidoptera for release in
suitable localities to repopulate areas
with species that have become un-
common for some reason. | must here
note certain conditions for rearing
species for release, and | would be
grateful if Members would inform me
of any personal efforts in this direc-
tion, giving the species they are
rearing and the localities these are
to be released in.
Suitable methods and conditions
for releasing bred stock are as
follows:
A. Augmenting a species by pro-
tected breeding of additional speci-
mens procured from that same
habitat. Such breeding should be
done in as near natural conditions as
possible. This method is being used
successfully with some species includ-
ing the Large Copper (Lycaena dispar
Haw.) at Woodwalton Fen.
B. Putting down of a species in a
new area where it has never occurred
or from which it has disappeared
owing to some detrimental factor
such as ploughing up, forestry
changes, etc. This is not always
successful as it is difficult to gauge all
the factors, and micro-climatic or soil
factors may be disadvantageous.
Whenever such a venture is pro-
posed it is well to obtain the interest
of the landowner and the County
Naturalists Trust, and inform the
Natural History Museum at South
Kensington, S.W. 7, of what you are
doing (Mr Howarth is an AES
Member).
C. General release of excess bred
specimens of common species (e.g.,
Vanessids). This is a very haphazard
business and little data are available
on the effect or success of such
operations. With species which natur-
ally have a wide dispersal it is prob-
able that no harm can be done.
D. Release of introduced species.
AES BULLETIN, VOL. 27
This should be done only with species
which are restricted in habitat if any
proper records are to be kept and
the chance of the introduction spread-
ing is to be avoided. Parasites and
virus diseases are of course a danger
to our native species, which may not
be prepared for them, and generally
| would advise against any intro-
duction of foreign species, or foreign
stocks of our native butterflies.
The Amateur Conservation Group
A newsletter will be sent to each
member now and then, and especially
when group activities become inter-
esting and important projects are
suggested. In November of each year
an annual report will be prepared
with all members of the Group
contributing articles.
Members should keep the convener
well informed of their activities
throughout the season, and of their
plans before they become active in

Well, that’s the ‘big three’ of the
glands of internal secretion. But as
stated above, there are other neuro-
secretory cells, together with their
corpus cardiacum equivalents, in the
ventral nerve cord, though functions
have not been assigned to all of them
by any means. Some of the cells seem
to be associated with the female
reproductive cycle; some with con-
ditions of dryness; some show vari-
ations in secretory rate in a diurnal
cycle. Conversely, a recently dis-
covered hormone, Bursicon, has been
shown to be produced from the last
abdominal ganglion, yet the cells pro-
ducing the substance have not been
isolated. A diuretic (‘‘water releas-
ing’’) hormone has been traced back
to the cells which produce it in the
last ganglion, but this is an isolated
instance.
Fig. 4 shows a selection of the
endocrine effects so far discovered.
The diagram, as indeed this article,
has been abbreviated and simplified
quite considerably, and some rather
naughty generalisations made. If you
want to find out more about insect
hormones, V. B. Wigglesworth’s
‘Principles of Insect Physiology’ will
provide a nice generalised account,
and V. J. A. Novak’s ‘Insect Hormones’
will give a much more complex,
complete and frustrating account.
Frustrating because it is only when
you start to investigate in detail and
depth that you find out just how
little is known, and how uncertain
is the basis of all the lovely theories!
In the second half of this article, |
will describe some relatively simple
experiments which should give food
for thought, and also give some idea
of how you can do some original
research into insect hormones.

AN ECOLOGICAL APPROACH
TO LIGHT-TRAPPING—5
Weather Relationships
In previous articles (Bull. amat. Ent.
Soc., 25: 29-31, 65-7, 134-5), attempts
were made to isolate factors which
affected the quantity of insects caught
in a light-trap. This section makes no
such attempt but tries to give an idea
of the overall situation.
Weather conditions, which were
recorded simply in terms of either
the presence or absence of cloud,
rain, snow, fog or moon, were
divided into seven distinct categories,
as shown on the histograms (Figs. |-8).
Since these five terms were accom-
panied by more important changes in
the physical environment a table has
been constructed to illustrate them
(Table |).
The Orders of insects have been
classified into groups (see Table 2)
according to their reactions to the
factors listed. The majority of insects,
which have been classified into the
first group, preferred to fly on either
very cloudy or extremely clear
nights. Weather stability, that is the
continuation of prevailing conditions,
would appear to be important, for
far fewer insects flew on moonlit
nights interrupted by cloud than
would have been expected from the
results of the two factors alone.
Group Ib was less definite in its
second choice of ideal weather, but
this was probably due to insufficient
material collected in the samples.
First choice was mainly governed by
temperature: for instance Psocids,
with the highest temperature thresh-
old (Bull. amat. Ent. Soc., 25: 29), only
occurred when there was an effective
cloud cover after a hot day.
When stability of the animal
environment was disrupted for in-
stance by short intervals of rain,
flying activity was drastically reduced.

Table 2: Groups of insects according to reactions to environmental factors.
eroptera and Hemiptera tended to
rest under these conditions, but
larger, stronger insects like beetles
and caddisflies continued flying,
perhaps protected by their specialised
cuticle. Both types of insect have
produced an effective water-repellant
surface, although they have achieved
it in entirely different ways. Beetles |
have the body surface strengthened
and streamlined, while caddisflies
have their bodies covered with an
irregular coat of hairs to prevent
water-droplets from adhering.
Any increase in the amount of rain
further reduced the number of
insects flying, although this did not
apply to caddisflies which preferred
these conditions. It is interesting that
these aquatic insects sometimes have
a pattern of behaviour which includes
laying eggs below the water-surface,
again indicating their indifference to
this medium.
Insects were never captured in
extremely bad weather such as fog or
snow for two principal reasons.
Firstly, the visibility especially in fog
was reduced to a level below which
the light source ceased to be an
attraction; and secondly, snow
particles caused severe damage to
any insects flying.
This latter view is in keeping with
the idea of aerial stability. Another
factor which tends to reduce stability
and obstruct insect flight, but which
has not been discussed here, is the
presence of wind currents.
The picture obtained, then, is of a
temporary environment, the insect
population of which is dependent on
its stability.

HAMMOND’S BOX
At a recent meeting of the South
London Entomological Society, a
small box was passed round which
had been used for posting delicate
specimens. After the box had been
thrown in the air several times and
caught by clapping loudly between
the hands the box was dropped from
a height of about three feet on to the
bare table in front of the chairman.
On opening the box the specimen
pinned inside—a syrphid fly, Volucella
pellucens Linn., caught as long ago as
1932—was found to be still intact.
This was made possible by suspending
a smaller box inside a larger one, on
two rubber bands secured by screw-
eyes and long paper fasteners as
shown in the figure. The rubber bands
should be under slight tension and
adjusted by experiment. Mr C. O.
Hammond, who made the box, has
had it posted forwards and backwards
on many occasions without damage
to the insects enclosed.

Some considerations
Plotting the distribution, range, or
dispersal, etc., of species of insects
can be a fairly straightforward task.
We need arm ourselves only with
some instrument by means of which
to capture specimens of interest, with
enough information to be sure of
identification, and with a map and a
' notebook to enable us to record our
finds. Immature stages are recorded
_in the same way as the adults, whilst
/a certain proportion of the adult
catch is generally retained for
reference purposes.
Having set about the study in this
way, we have gained, over some years,
-a certain knowledge of insect distri-
bution. The fact that we also collect
specimens simply because we enjoy
collecting them is a matter for the
psychologists. It is only likely to be of
consequence to those of similar
interests if we set off once yearly for
the British haunts of such insects as
the Large Blue Butterfly (Maculinea
arion Linn.), in the form of a ‘vacuum-
cleaner in entomologist’s clothing’.
We do not do this, of course, if we
also like insects.
— Work of the kind mentioned in the
first paragraph is extremely useful.

Without the notebooks of amateurs,
textbooks would involve their
authors in years of intense study over
an almost impossibly vast area, and
would probably be thus prohibitively
priced. As it is, an amateur is able to
devote his spare time to making an
intensive, personal study of a res-
tricted area, often over two or three
decades. The result of this field-work
is a knowledge of the following
aspects of the biology of each species
studied:
a. Its distribution within a certain
area—usually representing only a
part of its total range.
b. the sub-habitats in which its life-
cycle is enacted.
c. the dates of its appearance in its
various stages.
Perhaps inadvertently, an insight
is also gained into the following:
d. The distribution of the foodplants
(or other food material) of the
growing stage.
e. the distribution of the food-
sources of the imago.
f. terrain preference differences in
allied, and in distantly related,
forms.
. the influence of the weather, and
of light-values, on activity (see,
26
e.g., Badmin, in Bull. amat. Ent.
Soc. 24: 23-4, etc.)
This is the sort of knowledge |
spent several years gathering in the
British Isles.
On my entering new pastures in
which there are few entomologists,
however, it was clear that my distri-
butional studies would have to extend
deeper than hitherto if | was to make
a serious attempt at providing some
solutions to the many queries which
have been the end-points of previous
research in other parts of the globe.
| chose to begin this series of
articles with the butterflies for
several reasons, not the least of
which, | confess, was my own interest
in them. The first stage of the work
has been completed, and is presented
in these two articles. It consisted in =
obtaining copies of the recent text-
books and extracting from them the
details of the broad distribution
(over some 325,000 sq. km. of land
surface) of butterfly species. In the
process of doing this, three problems
presented themselves to me.
Firstly, Finland, unlike Britain, is
not conveniently surrounded by a
natural ‘fence’, the sea, which prob-
ably forms a barrier to the dispersal
of the majority of insect species in the
British Isles. Finland adjoins the
U.S.S.R. to the east, Norway to the
north, and Sweden partly along the
western side. The marine waters of
the Gulf of Bothnia and the Gulf of
Finland form only a partial barrier to
dispersal, this being continuous on
the western, south-western and
southern sides. Ahvenanmaa and its
associated islands, although surround-
ed by water, do share a number of
species with the southern part of the
mainland.
Secondly, the information imparted
in the most recent work of national
importance (Gullander, 1959) is not
really so up-to-date as one would
like it to be.
FEBRUARY, 1968
Thirdly, | have yet to discover the |
basis for the division into the so-
called ‘‘Natural historical areas of
Finland’’ (see map, Bull. amat. Ent. |
Soc. 26: 120). They do not correspond
to the published climatic, geological |
or vegetational patterns; neither do
they relate exactly to rural commu- |
nes. Again, these areas are of varying
sizes and are all too large to be of any |
great use as actual distribution indica-
tors. Each species is simply recorded
as being either present in, or absent |
from, each area. The notes given by |
Gullander on habitat preferences,
however, enable one to narrow down
the areas to a certain extent. Unfortu- |
nately, the cost of buying a complete |
set of the local |:20,000 maps would
be very high, and it is only on these
maps. that individual forest and
swamp types, lakes, altitude, agri- }
cultural areas, and so on, are marked.
It is necessary that | should gather
further information in order to be
able to represent specific ranges by a
series of dots, rather than by a
smaller number of “‘covering’’ areas
of great expanse. | am _ working
through the periodicals indicated
under ‘references’ as well as covering
as large an area as possible during my
field activities this season.
Whilst it is a fairly easy task to
build up in this way a comprehensive
set of specific distribution charts, it
is by no means so easy to isolate the
factors which actually govern ranges.
This isolation is rendered even more
difficult in that, even foodplant dis-
tinctions aside, the spread of butterfly
species appears to be influenced, not
by a single factor or combination of
factor values, but by more or less
exclusive combinations acting on
each species. It is thus essential that
a thorough study be made of all
possible factors. This means going
somewhat further than the limits of
the investigations briefly enumerated
in the opening paragraph. It entails,
AES BULLETIN, VOL. 27
for example, making careful studies
of larval foodplants and of other
vegetational entities, correlating their
dispersal with those of the butterflies.
Here again, published facts do not
meet our requirements. A com-
parison between the distribution of
the Finnish species of Satyridae and
that of the larval foodplants, using
published matter, showed that the
plants in almost every case had been
recorded as residents of places in
which the insects are not known to
occur.
| hope that something will come of
this project because | feel that, having
decided that insect species are
adapted to their environments, we
all ought to try to contribute some-
thing towards finding out what factors
are instrumental in preventing each
species from widening its range. Only
when this information has been
obtained can those whose task it is to
mplement conservation projects in
3ritain be suitably armed.
Talk of conservation in Britain, one
nay feel, is out of place in an article
ourporting to throw some light on
the distribution of butterflies in
‘inland. | feel that they are both part
of the same sphere. Members read
he Bulletin because they are inter-
ssted in entomology, and | believe
hat conservation is of major impor-
ance to those who like insects and
vho also gain great pleasure from
collecting them.

BUTTERFLIES IN FRANCE
AND SPAIN AUGUST-
SEPTEMBER 1966
Last summer my wife and | spent a
three weeks’ camping holiday in
south-western France and northern
Spain. Although this was not primar-
ily a ‘butterflying’ trip, my wife’s
tolerance enabled me to do a fair
amount of collecting.
We had no fixed plans but intended
to end up on the Costa Brava,
although we were in no particular
hurry to get there. Leaving New-
haven early on the morning of 20th
August we arrived at Dieppe at about
lunch time. Having passed through
customs we set off southwards stop-
ping for tea just north of Blois. Here
| unpacked my net for the first time.
In some scrub land and long grass
beside the road | found Arethusana
arethusa D and S and Lysandra coridon
Poda (Chalkhill Blue) to be common.
| was pleasantly surprised to take four
L. coridon var. syngrapha Kef. in about
five minutes. | also took a couple of
Colias hyale Linn. (Pale Clouded
Yellow). Naturally | was very pleased
with this excellent start to the
holiday.
We spent the night just south of
Chateauroux, being then on the N20
which we subsequently followed
right to Andorra. Early next morning
we ran into quite thick fog which did
not clear for some time. By midday
we were just north of Cahors and
decided to stop for lunch. | had a look
round, again L. coridon was common
and much to my amazement | caught
a further five var. syngrapha. | do not
know if this var. is very much more
common in France or whether | just
picked two lucky sites. Small fritill-
aries abounded and | noted five
different species in one small field,
namely Melitaea didyma Esp., Melitaea
phoebe Schiff., Mellicta deione Gr.,
=
;
§
&
Mellicta parthenoides Kef., and
Clossiana dia Linn. | also caught a very
nice abberation of M. deione. Hesperia
comma Linn. (Silver Spotted Skipper)
was quite numerous.
We continued south that afternoon
spending the night just outside
Aix-les-Thermes almost at the foot
of the Pyrenees. Next morning while
we waited for the dew on the tent to
dry before striking camp | saw a
number of Brintesia circe Fab. and
took a specimen of Hipparchia alcyone
Schiff.
As we drove through Aix-les-
Thermes we were surprised to see a
number of people with their feet in
what looked like a large paddling
pool in the main square. What
amazed us most was the steam
rising from the water. The significance
of the name of the place then dawned
on us and we realized that this must
have been hot water from a natural
spring.
The road up the mountain was very
impressive. We traversed back and
forth and always upward, and some of
the views were quite breathtaking.
The road signs warning against
‘Troupeaux’ were fully justified. The
big tawny cows, heaven knows what
breed, just stood in the road while
the line of cars and lorries had to
weave its way between them.
Having passed through the customs
and filled up with petrol at the
battery of pumps right at the top of
the pass, petrol in Andorra being
almost a gift after the high French
prices, we stopped to admire the
view down into Andorra and to give
the car a breather—to say nothing of
the driver. A number of smallish
brown butterflies were sighted and
amongst them some that looked
almost purple. These proved to be all
the same species, Erebia cassioides
Hohenwarth., at first sight rather a
dull butterfly but at certain angles
the wings have a beautiful purplish

sheen.
We stopped for lunch in Andorra.
Polyommatus icarus Rott. (Common
Blue), L. coridon and Aglais urticae
Linn. (Small Tortoiseshell) were
common. | also saw a couple of
specimens of Lysandra bellargus Rott.
(Adonis Blue) and one rather battered
Mesoacidalia charlotta Haw. (Dark
Green Fritillary).
On leaving Andorra we decided not
to drive straignt to the Costa Brava
but to see a bit more of Spain first.
Instead of driving westward to
Puigecerda we therefore set off
southwards on the main road to
Lerida. After some fifty kilometres
we took a more minor road going
east. While stopping for tea beside a
a nice specimen of Limenitis anonyma
Lewin and a couple of Everes argiades
Pall. (Short-tailed Blue).
We camped for the night by the
Rio Cardonna just outside the town
of the same name. It was a poor spot
for butterflies, although there were
a few Lysandra hispana H.-S. about, so
| tried my hand with a fly rod. | did
not raise a thing and in fact saw no
sign of fish at all in the very fast
water of the river.
Next morning we packed up again
and moved on through Suria and
Belsareny. | am giving the names of
the towns so that readers with
suitable maps can plot our progress.
The weather was beautiful and
after a few brief stops to pick black-
berries my wife and | decided we had
had enough of the car for a bit and
that we should make the best of the
sunshine. Naturally | made sure that
we stopped in what looked like a
good place for butterflies. The
country was hilly and wooded with
clearings and small terraced fields.
Even before we had stopped the car |
had spotted vast numbers of Leptidea
sinapis Linn. (Wood White), which
AES BULLETIN, VOL. 27
were literally everywhere flitting
between the trees and in the small
fields. | have never seen so many any-
where before. | took those | wanted
by simply netting those that came
within range while | sat in the sun
eating my sandwiches. Fritillaries
were common in the fields and | saw
M. didyma, M. phoebe, M. deione and
-C. dia, and also a couple of specimens
of Issoria lathonia Linn. (Queen of
Spain Fritillary).
‘Blues’ were also numerous,
mainly L. hispana and P. icarus but |
‘also saw one Lampides boeticus Linn.
| (Long-tailed Blue) and took two
‘female Agrodiaetus damon _ Schiff.
Erynnis tages Linn. (Dingy Skipper)
was quite numerous. Colias australis
Verity (New Clouded Yellow) and C.
)croceus Fourcr. (Clouded Yellow)
were also taken.
By mid afternoon we had set off
again, having driven through Vich we
took the road to San Hilario. We
‘soon found ourselves climbing up and
up once more. The road was literally
cut into the side of the mountain and
the drop at the edge was rather
alarming, especially as the road was
not very wide and we were con-
stantly expecting a large lorry to
come tearing round the corner in
front of us. A number did but fortu-
nately we managed to squeeze by on
each occasion. Having reached the
top the terrain levelled off a bit and
the downward road was nothing like
sO steep or spectacular. We drove
through a delightful open valley and
decided to stop for the night.
Next morning we found our
surroundings so attractive that we
, agreed to stay for the day. There were
a number of very worn Argynnis
paphia Linn. (Silver-washed Fritillary)
),and Fabriciana adippe Rott. (High
»Brown Fritillary) about and Vanessa
cardui Linn. was also quite common.
,| saw a couple of rather battered
) specimens of Agapetes lachesis Huebn.
29
and also a couple of Hipparchia semele
Linn. (Grayling).
‘Blues’ were not numerous but |
took specimens of three skippers,
Pyrgus cirsii Rambur, the smaller
Spialia sertorius Hoffmansegg., and
H. comma Linn. | also took one Papilio
machaon Linn. (Swallowtail) and one
Iphiclides feisthameli Dup., the only
Papilionids | came across during the
holiday.
Next morning the weather was
cloudy and threatening rain so we
moved on to the coast. Going via San
Hilario, Gerona and Parafrugell to
Tamariu, we arrived about midday
and set up camp. We spent two and a
half days in Tamariu. Except for one
sunny morning the weather was
cloudy and we had two mammoth
thunderstorms. | did not do much
collecting, except on the sunny
morning. M. didyma and M. deione
were quite numerous as were the
‘Blues’ Syntarucus pirithous Linn. and
P. icarus, | also saw a few specimens of
L. boeticus and took a couple of the
skipper Carcharodus alceae Esp. and
one of Gegenes nostrodamus Fab. C.
croceus and Pararge aegeria Linn.
were common and Hipparchia fagi
Scop. were quite numerous.
As the weather was still bad on the
third day we decided to _ leave.
Neither of us had previously been to
the Atlantic coast so we thought we
would work our way across. After
studying the map it appeared that the
roads in France were better than the
Spanish ones, so we set off to recross
the Pyrenees. This time we went by
the more direct route Gerona,
Banolas, Olot, Ripoll and Puigcerda,
nothing like so attractive as the way
we had come but much quicker.
When we crossed into France we
did not take the N20, but the N16 to
Mont Louis and then the NI 18 to find
a large lake which we had spotted on
the map as a potential camping place.
We arrived as dusk was falling and
30
pitched our tent right beside the
lake which turned out to be a huge
reservoir.
Despite the fact that we were at
more than 5,000 feet the next day
was hot. Erebia neoridas Boisd. was
very common and | also caught a few
specimens of the copper Heodes
virgaureae Linn. and one I. lathonia.
That evening the clouds came down
over the mountains and completely
enveloped us. Next morning dawned
sunny but it was very much colder.
By mid morning however dark clouds
had begun to gather and by lunch
time it had started to rain a hard,
cold, driving rain that looked as if it
had set in for the day. We therefore
struck camp and set off to descend the
Pyrenees on the French side.
Coming out of the mountains at.
Axat we travelled westwards stop-
ping for the night at Foix, a most
attractive town. Next morning was
still wet and we continued through
Tarbes, Pau and Bayonne. By the
time we had reached the Atlantic the
weather had begun to clear but the
sea was very rough and bathing was
forbidden on all the beaches we
could find. By now it was getting late
so we took a side road inland to find
somewhere to camp for the night.
The following day dawned clear and
sunny. It was Ist September and we
only had nine days of our three weeks
to go. On studying the map we found
that we were very near the Spanish
border. A quick count down on our
finances persuaded us that back into
Spain was the place for us. We could
have almost two days in Spain for the
price of one in France, or so my wife
informed me. We crossed the border
at a tiny frontier post on a little back
road feeling very mean as we had to
get the single Spanish guard away
from his breakfast and he had to
chase the chickens away in order to
lift the barrier.
Once in Spain the road dropped
FEBRUARY, 1968
sharply and we arrived at the delight- |
ful little town of Vera. From here we
headed towards Irun and the coast,
the road following the river Bidasoa
most of the way. It was while we
stopped briefly on the river bank that
| took a specimen of Araschnia levana |
Linn. This may be a very interesting |:
capture as | see that R. F. Bretherton
(1966) in his ‘Distribution List of the |
Butterflies of Western and Southern
Europe’ while referring to this species
says it is “‘not yet certainly known
from Spain’’. This specimen was
certainly taken in Spain, although
only just.
We drove through Irun and the
smaller Fuenterrabia and out on to
the cliff top. Having found a secluded
spot to camp in the pine trees, we
were so enchanted by the sea, cliffs
and the little beaches that we spent
the next four days here. Except for
one day when we visited San
Sebastian, the weather was good.
While my wife sunbathed | did quite
a lot of ‘butterflying’ along the cliffs.
The ‘Blues’ were the most numerous,
and of these Everes argiades was very
common and | took one specimen of
E. alsetas flying with it. L. boeticus was
also quite numerous as was P. icarus.
A number of other species were
common especially C. croceus, Maniola
jurtina Linn. (Meadow Brown) and E.
tages. | was pleased to take a few
specimens of that attractive satyrid
Minois dryas Scop. which must have
been pretty well at the edge of its
range. | also found the small dark
copper Heodes tityrus Poda and took a
single specimen of Pararge maera
Linn. In addition Vanessa atalanta
Linn. (Red Admiral) and I/nachis io
Linn. (Peacock) were seen.
Starting on our way home we
spent two days on the coast north of
Bayonne between Hossegor and
Vieux-Boucau—not a good place for
butterflies, being mainly sand and
pine trees. L. boeticus was, however,
AES BULLETIN, VOL. 27
very numerous.
We spent our last day in France in
the Loire valley. Then it was back to
England until next year’s summer
holiday.

near Brockenhurst, Hampshire. The
group was able to find many of the
insects they wanted and by camping
had the great advantage over Youth
Hostelling (which | prefer) in that
they were able to collect moths at
night. The camp site unfortunately
proved to be a little boggy but this
was compensated for by everyone
having a jolly good time and a
successful! trip to the Isle of Wight in
search of the Glanville Fritillary
(Melitaea cinxia Linn.). A further
Teen International camp was arranged
during July where one of the inter-
esting insects caught was said to be
\the rare pallida variety of the Small
Skipper (Thymelicus sylvestris Poda).
- On /7th August Rob Dransfield and
council member Ron Allen, of 26
3|
Burnside Road, Dagenham, Essex,
set off for a cycling expedition from
Dieppe to eventually reach the
Ardennes on the east Belgian border.
They reached Aunale at about 12
o'clock, on a—by then—fine sunny
day and found one field there where
butterflies abounded. There were
Pale Clouded Yellow (Colias hyale
Linn.) and Chalkhill Blues (Lysandra
coridon Poda) as well as other ‘Blues’,
Skippers and commoner species like
the Brimstone (Gonepteryx rhamni
Linn.).
After camping at Amiens the
explorers pressed on into the Valley
of the Somme where flies were
plentiful but very few interesting
Lepidoptera apart from a_ large
unidentified Nymphalid which man-
aged to duck the net, and a dwarf (?)
Green-veined White (Pieris napi
Linn.). Further on near Estrees a
clover field was found covered with
Clouded Yellows (Colias croceus
Fourcr.) and Peacocks (Nymphalis io
Linn.). The night was spent in the
barn of a very understanding farmer
just outside Homblieres, near St
Quentin. (Why doesn’t school French
match that they speak in France?)
On Wednesday, heading for
Eteigneres, our friends found quite
large numbers of butterflies and flies
on the umbellifers. Of particular
interest was the European Map
Butterfly (Araschnia levana Linn.),
which at first glance looked very
much like the White Admiral
(Limenitis camilia Linn.).
After having met light rain the duo
became drenched as they ran into
violent thunderstorms in the Meuse
valley. The weather did not really
improve when they finally made
camp just north of Revin in the
Ardennes.
Rob caught two further species of
‘Copper’ and several Fox Moth
larvae (Macrothylacia rubi Linn.). The
13th was his lucky day when near
32
Hautes Buttes in the mountains he
netted a perfect specimen of the
Camberwell Beauty (Nymphalis antio-
pa Linn.) as well as finding a field full
of ‘Coppers’ and a single Pearl-
bordered Fritillary (Argynnis selene
Schiff.). On the same day in an
orchard near Montherme he caught
a continental Wall Butterfly (Pararge
sp.). At night the flowers surrounding
the camp site held large numbers of
Noctuid moths. One sweep brought
in eight or nine at a time.
On the [5th, on the return to
Amiens, the first Swallowtail (Papilio
machaon Linn.) was seen but not
taken. The two boys split up at
Amiens and Rob turned towards
Paris for a spot of sightseeing. On the
way he did manage to catch a rather
battered male Swallowtail and later a
female which laid only two eggs. He
just missed catching a Long-tailed
Blue (Lampides boeticus Linn.).
On the way back to Dieppe the
weather was glorious and although it
was by now rather late in the season
large numbers of ‘Blues’ were seen
on a hill near Meulon including the
Silver-Studded Blue (Plebeius argus
Linn.), the Small Blue (Cupido mini-
mus Fuessl.) and a few Adonis Blues
(Lysandra_ bellargus Rott.). A_ field
further on also proved to be filled
with ‘Blues’ and Clouded Yellows
including the light var. helice variety.
These together with the Pale Clouded
Yellow were abundant everywhere.
The only different species encounter-
ed on the way back to the coast was
the Holly Blue (Celastrina argiolus
Linn.)—on, believe it or not, Holly
(Ilex aquifolium Linn.).
Rob concludes by saying that it was
most noticeable how similar the
species around Paris are to ours at
the same time of the year while a
totally different group was found in
the Ardenne mountains. His only
other comment was on the roads of
Northern France. They are not made

for the Council members to choose
those which deserved special prizes.

for his “‘Common Moths of North
Wales’’. | was glad | did not have to

Two organised groups put on a
good show: the Teen International
and the Silkmoth Rearers’ Group.
| was particularly pleased to see
Miss Barbara Brent exhibit ‘‘British
Moths’’. It’s time more girls came
forward to show the boys they can
also take an intelligent interest in
Natural History.
| also found the joint venture
which M. S. Collins (3975J) helped to
produce—‘‘A family tree of Coleop-
tera’’—very refreshing. (Anyone
would think that butterflies were the
only insects in the world. | like
beetles myself).
If any of you live within striking
distance of St Ives, Huntingdon, and
have difficulty in getting to the AES

us.

soon as we are short of time and

hoppers, weevils and even spiders.

Quite often, while perusing litera-
ture outside my own immediate
spheres of study, | discover an item
which interests me not simply as
another piece of scientific knowledge,
but rather as a novel piece of infor-
‘mation easily recalled to mind for a

Early records will be welcome this
year.
Very best wishes for the New Year.

The Gum-spitting Spider (Scytodes thoracica Latr.)
Jaakko Syrjamaki reports his obser-
vations on dusk-swarming in Chirono-

observations were made at the Lammi
Biological Station, South Finland (61 °
03’ N; 25° 03’ E.), during the late
summer of 1965.
‘““One evening, when watching the

ers flew very vigorously to the
vicinity of my mouth. This led me to
stop humming, whereupon the males

but as neither of these observations
was made in Britain, if one of our
Dipterists is sufficiently interested,
he could perhaps perform some
original work in the field using, for
example, a set of tuning forks. It
might then be possible to discover
what vibrations attract the males of
the various British species, hence to
contribute to the knowledge respect-
ing mate-attraction in the females.

THE DEATH’S HEAD
HAWKMOTH IN
BEDFORDSHIRE
On August 2nd this year (1967) |
was given a caterpillar of the Death’s
Head Hawkmoth (Acherontia atropos
Linn.) which was found near some
potato plants in an allotment at
Bedford. It was ready to pupate and
when it was put in a container filled
with bulb fibre it soon burrowed out
- of sight. The following day another
one was found by a friend of mine
“near where the first was discovered.
These caterpillars are the first of their
“species to be recorded in Bedford-

EDITORIAL
Junior Members will be interested
to learn of the attractive Junior Con-
servation Prize for 1968 (see the
article below), which has been set up
thanks to the interest and generosity
of Sir Robert Saundby, and of Mr S.
J. Whitehouse, and | hope that many
Juniors will enter. It is not possible
to over-emphasize the importance of
conservation today, nor to stress too
much that there is something that
everyone (and this applies not only to
Junior Members, of course) can do in
this direction. Our Juniors always
make an impressive effort at the
Annual Exhibition: let them direct
their energies here too.
As Members may be aware, this is
the last Bulletin which will appear
under my Editorship, and | would
like to take this opportunity of
thanking all those who have helped—
in contributing to the magazine or in
other ways—to make my task a
pleasant one. It is with great pleasure,
too, that | introduce my successor,
Mr David Corke, who has very kindly
volunteered his services and has
recently been helping in the prepar-
ation of the Bulletin. Could | ask that
Members try to simplify his job in the
difficult transitional period: firstly by
submitting plenty of material; and
secondly by following wherever poss-
ible the guidance for authors given in

JUNIOR CONSERVATION
PRIZE
[The Junior Conservation Prizes
kindly set up by Mr S. J. Whitehouse
and Sir Robert Saundby (see Bull.
amat. Ent. Soc., 25: 37; 73-4), failed to
attract an entry in 1967, and no
prize was awarded for that year. The
donors of the prizes have, however,
generously agreed to make a single
combined prize worth £5 available
for this year, and more specific
suggestions for entries are also given
to encourage Juniors to try for this
very worthwhile prize.]
Junior Conservation Prize 1968
The Junior Conservation Prize for
1968—to be worth £5—will be
awarded to the Junior Member (or
group of Members) who contributes
to the Bulletin (with the addition of
supporting material if required) the
best report of his service to nature
conservation during 1967 and/or
1968. The purpose of the prize is to
encourage Junior Members to take
an interest and participate actively in
conservation matters. To enable them
to enter into a rewarding participa-
tion of this nature, some suggestions
are given below, and fall into two
categories. The first includes ideas for
fieldwork directed towards conser-
38
vation. The second allows scope for
constructive suggestions as to how
the problems with which we are
faced today when attempting to
conserve our insects may be met.
Note that conservation of Orders
other than the Lepidoptera is neces-
sary in many cases and that our
knowledge of the Lepidoptera—let
alone these other Orders—is often
insufficient in an area for useful con-
servation work to be done before
knowledge is collected: knowledge
towards which any keen Junior
Member could contribute.
First category
|. A-survey of the status of a species
in an area, perhaps an area likely to
be threatened by future development.
2. A study of the ecology of a given
insect species, with particular ref-
erence to the aspects possibly vulner-
able to changes in the habitat. Find
out how the species fits into its
niche in the habitat and the factors
there by which it could be affected.
3. A survey (of a Nature Reserve or
other area) in co-operation with the
local Naturalists’ Trust, etc.—fre-
quently an entomologist is lacking
from a local survey team, yet a com-
plete knowledge of all the fauna is
essential to direct conservation
properly.
4. A report of the general assistance
given to a conservation society,
Naturalists’ Trust, etc.
5. Work in a habitat—individually
or with a society or group—aimed at
the conservation of an insect species.
Before this can be done it is essential
to know the species’ habits thoroughly
(see 2 above).
Second category
1. An area of entomological value
near your home is threatened by a
housing development: what would
you do about it?
2. How would you set about an
ecological survey of a threatened
area?
MAY, 1968 |
3. Indicate a species of our macro-)
lepidoptera which you consider to be.
in serious danger, and explain why.
4. What do you regard as the chief
threat to our insect fauna today, and
why?
If you can write a contribution on
one of the above, why not spare the
extra time and answer where applic- —
able by a practical demonstration? _

COLLECTING NOTES
MAY, 1968
The Smaller Moths
Lathronympha strigana Fab. (hyperi-
cana Huebn.). Mr Bradford’s note
reads as follows:— ‘‘l have bred this.
moth along with Euspilapteryx auro-
gutella Zell. from Perforate St John’s”
Wort (Hypericum perforatum Linn.)
which | discovered growing near)
some gravel pits at Park Street,
Hertfordshire. In June | dug up a
clump of the plant and, on arriving ©
home, put it in a large flowerpot and |
kept it outdoors in a large container.
Eventually about a dozen of each of
the moths emerged. |
t
‘The forewings of L. strigana are of ©
a brownish orange colour. There are.
leaden metallic streaks on the costa’
and the ocellus also has lighter:
metallic patches and black streaks.
The hindwings are grey. The adult is
on the wing in June and July and the
larva feeds in spun shoots of the
foodplant.”’
This is a common species with a)
wide range extending at least as far
as the North of England. If you)

St John’s Wort in June, you are also

| likely to come across the larvae ‘of

‘thas a similar range. A third species
‘ associated with the same foodplant is
‘ Argyritis (Aristotelia) atrella Haw.,
the larva of which mines the stems in

hamwood. Whilst there | took several
specimens of Mompha fulvescens Haw.
and M. raschkiella Zell. flying around
Epilobium spp. Also in the spun
leaves and shoots of the Great
Willow-herb (E. hirsutum Linn.) |
found about a dozen larvae of what
proved to be Clepsis costana Fab. The
larvae were of the energetic type,
wriggling violently and often drop-
ping to the ground. They were of a
40
dark brown colour—Meyrick states
grey-green or brownish green, but
my larvae were hardly green but of a
deep brown. The adults all emerged
between [5th and 26th June, which
may have been a little earlier than
their natural date of emergence.
“The overall colour of the fore-
wings is ochreous with darker brown
markings and spots. The hindwings
are a paler fuscous with darker
greyish brown markings. The larvae
are said to feed on various other
plants apart from Epilobium, including
Knapweed (Centaurea spp.), Marsh
Cinquefoil (Potentilla palustris Linn.),
Sea Aster (Aster tripolium Linn.) and
Sea Lavender (Limonium vulgare
MATE)
If you have taken any C. costana as
adults, you should examine them
carefully in case there is another
similar but little-known species
among them. This is Paramesia
gnomana Clerck which can be distin-
guished readily, since veins 7 and 8
in the forewing are stalked instead of
being separate.
Mr Bradford mentioned two species
of Mompha which he encountered in
his patch of Epilobium. The larvae of
the majority of the members of this
beautiful genus feed on the different
species of willow-herb during the
spring and summer months. M.
raschkiella Zell. is perhaps the easiest
to find, as it has become common
with the spread of its foodplant. This
is the Rose-bay Willow-herb or
Fireweed (Chamaenerion (Epilobium)
angustifolium (Linn.) Scop.). The larvae
mine the leaves, readily passing from
one leaf to another—a convenient
habit for the breeder. Tenanted
mines are of a yellowish green colour,
but they quickly turn white after the
larva has gone. The mines may be
sought for in May and June and again
in August and September. In late May,
too, M. conturbatella Huebn. spins the
topmost shoots of this willow-herb
MAY, 1968
together. The larvae are crimson-
brown; black or greyish larvae will }.
probably prove to be the ubiquitous }
Olethreutes lacunana Schiff. or one of ¥
the Cnephasias. A month later a much 9
less common species may be sought
in the stems; this is M. nodicolella
Fuchs, the larva of which makes a gall,
usually well above the base of the
stems.
The Great Willow-herb (E. hirsu-
tum Linn.) also repays the careful
searcher. You will now be too late
for M. propinquella Staint., which
mines the young leaves of this and
other willow-herbs in the early
months of the year. But May is the
season for M. ochraceella Curt.; after
mining the roots and lower stems, its
larvae burrow into the leaves for
‘pupation. They are not difficult to
find, but it is hard to keep the picked
plants in good condition; if enclosed,
they soon degenerate into a watery
mush, while if left in the open they
dry up and shrivel. Yet | have found
that the pupae of M. ochraceella
survive either misfortune, and the
species is consequently an easy one to
breed. Later on, in July, spinnings in
the terminal shoots of E. hirsutum
will contain larvae of M. fulvescens
Haw. The smaller, younger plants are
preferred. The pupa is in the spinning
or in a folded leaf hard by, and this
may be collected in August. M.
lacteella Steph. is said to mine the
leaves in August, but | have yet to}
encounter this species.
The smaller-flowered willow-herbs
are liable to cross with each other and
are not always easy to distinguish.
E. montanum Linn. (Broad-leaved
Willow-herb) is one of the commoner
species. This is the foodplant of M.
subbistrigella Haw., the larva of which
feeds in the seed-pods in July and
August; occupied pods are some-
times thickened or distorted. M.
decorella Steph. makes a gall in the
stem of this and closely-related
meES BULLETIN, VOL. 27
willow-herbs, often causing the plant
to divide and branch above the gall.
-) The larvae feed in July and pupate in
the gall, when a tiny fragment of the
white silk cocoon shows at the exit-
hole. The adults emerge between the
end of August and early October.
| have left the most beautiful of the
Momphas till last. The larvae of M.
sshrankella Huebn. can be found in
|) May and again in July mining the
upper leaves of E. montanum and other
small-flowered willow-herbs. The
) larvae, like those of M. raschiella, pass
from leaf to leaf, but unlike that
“species they pupate on the plant,
) spinning leaves together or folding
) them. This species is relatively rare
in the south-east of England, but gets
). commoner as one travels west. | have
) found it abundantly in the west of
lreland, where the foodplant is the
Marsh Willow-herb (E. palustre
Linn.).

The Hymenoptera Aculeata
A recent publication from the
United States prompts me to deal
» with the subject of trap nesting, and
commend it to my readers for action
during the 1968 season.
Many bees and wasps make their
| nests in cavities, either those they
' find pre-formed or those they bore
| themselves. The two commonest
| sites for such borings are the soil and
dead wood, and it is the latter with
which | want to deal here. Many
types of wood can be utilised particu-
larly if already tunnelled by beetles:
tree trunks, logs, bramble stems, and
| in gardens bean poles, fence posts,
| and the like. Hence the extension to
| providing deliberately fabricated trap
nests is a simple one.
Trap nests have been developed
over many years and are the subject
4|
of one of our own AES Leaflets (No. 7
G. S. Kloet, 1951, Some improved
devices for rearing Hymenoptera). The
recent book that | mentioned above
is: K. V. Krombein (1967) Trap-nesting
wasps and bees, Smithsonian Press,
Pp. vi 570, and is sub-titled Life
Histories, Nests, and Associates. This is
a massive compilation of the results
of twelve years work during which
about 3,400 nests of 118 industrious
species were examined. A simple trap
nest design was used, and the depth
of the study lies in the placement of
many traps in widely ranging areas
over many seasons. Thus it gives a
picture of the population occurring
in one place from season to season,
and also of the variation over a wide
geographical, and hence ecological,
range.
During the study new species were
discovered, new associations between
parasite and host established, and
many other facets of life histories and
behaviour studied. Some of the
species Krombein was dealing with
are holarctic in distribution and also
occur in this country. The large
eumenine wasp Ancistrocerus antilope
Panz. is one such species, and the
common leaf-cutter bee Megachile
centuncularis Linn. and the chrysid
Omalus aeneus Fab. are others. One
particular finding which could not
have easily been made by any other
method has a relevance to our fauna.
The eumenine wasp Ancistrocerus
catskill Sauss. occurs in two colour
forms previously thought of as sub-
species, the yellow-marked typical
form and the white-marked albophal-
eratus Sauss. Krombein found that
these two forms occurred together
in one nest as the progeny of one
mother on a number of occasions.
Hence the two forms are merely
colour forms of the same taxon. We
have in this country a similar situation
in the eumenine wasp Ancistrocerus
pictus Curt. which is yellow-marked
in most of its range, but in the north-
42
MAY, 1968
west exists as a white-marked form.
The name to be used for this species
is the subject of a taxonomic wrangle
and the priority of certain names
revolves arcund these two forms
being con-specific. Unequivocal data
from trap nests would help to sort
this out.
Krombein used very simple trap
nests, merely bored out lengths of
I” x |” planed, straight-grained
wood. Three sizes of hole were found
most useful, £” (3.2 mm), 3/16”
(4.8 mm) and 4” (6.4 mm). Holes of
these diameters were bored along the
length of pieces of wood to within
about 4” of the end. Lengths of 75
mm were used for 4” borings, and of
[65 mm for the larger sizes. Some
larger holes were used but would
probably not be profitable in this
country. Nests were put out in the
field in bundles of six, two of each
size. New traps were put out unsplit.
Any traps that were occupied were
split along their length with the
grain of the wood to allow study of
the nest contents. These were re-used
after cleaning and heat sterilisation,
the two halves being bound together
with adhesive tape.
| hope | have written enough to
interest some of my readers in this
type of study, and that you will be
placing some trap nests out this year.
If you cannot cover many different
areas, another way of adding interest
to your study would be to place
batches of different kinds of traps in
the same area. Perhaps in addition to
the wooden traps | have described,
bundles of bramble stems could be
prepared, some left intact for those
species which like to make their own
tunnel and some hollowed out.
To all those who try trap-nesting |
wish the best of luck, and | will deal
with the observations that should be
made on any nests collected in a
future article.

ANNUAL EXHIBITION
SATURDAY, 7th OCTOBER 1967 |
A wet morning gave way to the
fine warm afternoon we have been
privileged to enjoy over a number of
years. A large gathering of Members
and friends, including a most encour-
aging number of new faces, thronged
the hall from mid-day to the close
and obviously enjoyed the exhibits
and comprehensive array of ento-
mological impedimenta.
It was interesting to hear the views
expressed by two friends of the
author of this report who were
revisiting the Exhibition after a lapse
of many years. Their impressions
were practically identical. Generally
they thought the whole concept was
on a larger scale, there were more
exhibits, their presentation was more
ambitious and the former dominance
of British species was replaced by
world wide representation. Many
exhibitors were working to a theme
which besides adding considerably to
the interest for the viewers also pro-
vided a modicum of useful research.
Notably the sophisticated wares of
the modern dealer compared favour-
ably with the utility offerings of the
immediate post-war years. Plastic was
replacing wocd and glass and weighty
equipment had been succeeded by
more portable versions.
Four specialist groups attracted
well-deserved attention. Mr J. Heath
was in attendance recruiting recor-
ders for the Lepidoptera Distribution
Maps Scheme, initially confined to the
British Macro-lepidoptera. T.I.E.G.
members had combined to produce
an effective stand, including details of
their field meetings. The Silkmoth
Rearers’ Group, formerly one of the
Society's most vigorous sections
showed many species and coloured
photographs and is planning to
attract new members. The other new
section, the Amateur Conservation
Group, was busily raising enthusiasm
f
AES BULLETIN, VOL. 27
for its extremely worthwhile object-
ives.
The Council were particularly
gratified at the response of the
Junior Members. Once again Senior
Members had generously provided
two prizes for the most imaginative
effort and the selection of the two
winners was no mean task. The
eventual choice was :—
|. A. Lucas (3934J) ‘Survey of Happy
meailey;; 2. D. V. Lewis (5963)
‘Common Moths of N. Wales’. The
project of D. J. Longman (4042J)
‘Flight period of Moths’, was highly
commended.
In conclusion the Council wishes
to express their appreciation to the
organiser of the Exhibition, Mr B. F.
Skinner and his many willing helpers,
to Mr T. A. Robertson for his expert
insect setting demonstrations, to the
many Members who provided colour
slides covering various aspects of
‘Natural History and finally to extend
a welcome to all our Members and
friends to visit us again next year.
As in previous years as complete a
list as possible was made of the
exhibits in the time at our disposal.

came their way. African smallholders
in the Kikuyu area found their
potatoes, peas and beans completely
defoliated. | even found some larvae
attempting to eat banana leaves. A
further build up occurred in the Mt.
Kenya farming area later in 1966. The
larvae here attacked the green
“‘milky’’ stage of wheat, eating into
the unripe ears.
A Saturniid /mbrasia epimethia can
usually be found feeding on foliage of
the Black Wattle tree Acacia mearnsii
where plantations occur. These trees
are grown for their bark which is
used in the tanning process. African
smallholders also grow these trees
for making charcoal. During the early
months of 1966 these larvae occurred
in very large numbers. Trees in the
Gatundu area, some twenty miles
north of Nairobi, were defoliated by
the 6” spiny caterpillars. | recall
sitting quietly under some trees and
being able to hear the caterpillars
munching the foliage and the noise of
their frass falling to the ground.
One of my favourite collecting
grounds for the African Clouded
Yellow Colias electo Linn. were some
lucerne fields bordering the north
shores of Lake Naivasha. This lake is
one of several volcanic lakes of the
Great Rift Valley. The area is typical
of Kenya in that the scenery is
extremely beautiful. Looking across
the lake one can see the volcano Mt.
Longonot directly opposite, and to
the east lies Mt. Kinangop and the
Aberdares. The hills of the Gt. Rift
Valley Escarpment are visible in the
distance. A few hundred yards out
into the lake floats a mass of papyrus
in which Hippopotami remain during
the daytime. The strip of water
bordering the shore is thick with
patches of water lilies and thousands
of water birds. Pelicans swim in
groups of a dozen or more, while fish
eagles fly up and down, their phantom-
like cries echoing from the hills. The
87
sun beats down unrelentingly. The
area has only one disadvantage. Along
the edges of the lake mosquitoes
swarm in profusion and | can assure
everyone that they bite throughout
the day as well as in the evenings.
The East African race of Colias
electo Linn. pseudohecate Berger are
always in plentiful numbers here. One
could rarely make a sweep with a net
above the lucerne without catching
at least one butterfly. During the
1965-6 season the lucerne was liter-
ally crawling with caterpillars and
many of these butterflies migrated in
a south easterly direction later in the
season.
The female of the African Clouded
Yellow exhibits a range of colour
forms as does the British species. The
colours range from white through
cream, buff, and pale yellow to
orange. When butterflies of the
same species occur in large numbers
it is surprising how quickly one
learns to recognise individuals which
have slight differences in pigmen-
tation, without really having had a
good look at them. On several
occasions | have chased a particular
specimen across a field, ignoring
scores of others without really
knowing why, and on catching it |
have found it to be an interesting
variety. Perhaps it is because of acute
colour perception or it may be a
result of a slight difference in the
flight of the insect.
During this season, another butter-
fly was also present in large numbers
in the lucerne fields. The Painted
Lady Vanessa cardui Linn. breeding
up in vast numbers before migrating
northward to Europe. The larvae
were feeding on the weed Malva
verticillata Linn. (Mallow) which was
growing amongst the lucerne, along
the edges of the fields and in the
uncultivated areas where spray was
carried by the wind from the irriga-
tion pipes. | collected many of these
larvae and raised them in cages at my
88
AUGUST, 1968
home near Nairobi. Examination of
approximately one hundred adults
which later emerged, failed to reveal
any variations.
The infrequent occurrence of such
abnormally large numbers of certain
species of Lepidoptera raises the
question of the cause of these
increases. At the time of observing
the above example | thought that it
was probably the result of optimum
conditions for Lepidoptera in general
and, although | noted the fact that
many of the above mentioned species
are known migrants, | believed that
they migrated away from East Africa
and did not consider that they may
also migrate into East Africa.
Recent work by Brown and Swain
(1965) working on the African Army-
worm has shown that there is a
northerly origin for these moths. In
Kenya and N. Tanganyika the season
for Armyworm is from November to
May. During May to October no
trace can be found of any stage of this
species. Evidence from light traps in
Ethiopia, Somalia and Aden shows
that moths occur in these areas in
May and to October.
Data is available from twenty light
traps throughout East Africa. In the
1965-6 season the first arrival of
moths in Kenya was in November.
Examination of weather conditions
at the time show that their arrival
coincided with the southern limit of
the advancing north-easterly winds.
It must be assumed that large
numbers will breed up when con-
ditions are optimum. When this
happens in the northern areas, more
moths will reach East Africa. If con-
ditions are optimum here also,
fantastic numbers result, an example
of which is described here. This
pattern of build up of numbers is
probably as true for Vanessa cardui,
Anaphais mesentina and Colias electo
as it is for Spodoptera exempta.

LETTERS TO THE EDITOR
Sir,—I wish to make a plea for
restraint in the use of latin names in
Bulletin articles. | feel that two quite
differing appraisals should be made of
living things mentioned in an article.
On the one hand, specimens are
purposely identified either for direct
recording as such or for positive
identification with an associated
creature or plant. On the other hand,
some species may be mentioned
almost in passing, the finishing
touches of colour that transform a

rather monotonous screed into an
enjoyable article.
In a different context, there is also
the danger that a species that has by
no means been positively identified,
is pinpointed with a specific name.
How often do we see... . the Red
Wood Ant (Formica rufa Linn.)
Unless one is a myrmecologist, every
Wood Ant is F. rufa! Yet it could
easily be F. pratensis, rufa var. rufo
pratensis or even F. exsecta.
If one is describing a walk down a
quiet country lane and mentions the
heady perfume of honeysuckle, surely
that is sufficient. | personally, would
find it most irritating to read... the
heady perfume of Honeysuckle
(Lonicera periclymenum Linn.) ... but
the Bulletin abounds in this. | realise
that the specimen might just happen
to be L. caprifolium, but surely, unless
the honeysuckle forms a_ specific
| part in the ecology of that area which
is being reported and has been
specifically identified, this is of little
import. It is far better to be vague
than to be wrong.
Which of the two _ following
excerpts do you prefer, the first or
the second?
“We chose a Sessile Oak (Quercus
petraea Mattuschka) under which to
‘eat our lunch. The flies (Stomoxys

| repeat my plea. Can we not all
‘use discretion in the case of latin

names? A much neater method would
be to group all named specimens
together at the end of the article in
the form of a specific list. This would
surely be of more assistance to
readers who wished to make use of
identifications. | would hasten to
point out that my views are in no
way influenced by the fact that |

Sir,—I feel obliged to point out an
error in Mr. J. A. Wightman’s article
(Bull Amat. Ent. Soc, 27: Il) on
insect semen transfer, in which he
states that ‘‘land snails . . . transfer
semen enclosed in calcareous ‘love
darts: a:
This is quite untrue. The exchange
of darts merely stimulates the two
snails to insert their cirri into each
other’s vagina (the genital atria being
everted prior to the exchange of
darts). Small spermatophores pre-
pared in the flagellum travel through
the cirrus (=penis) to the other
snail’s spermatheca.

JUNIOR NEWS SECTION
Hello everyone. When you read
this you should all be enjoying a
glorious Summer so please flood me
out with reports!
Here are the answers to the Spring
Quiz:—
|. This was a catch question for, as
| am sure you all know, it is the
larvae of the Clothes Moth (Tineola
bisselliella Hummel) which eat cloth.
The adults eat nothing.
2. A drawing was wanted here of an
orange and black Rainbow Rove
Beetle (Paederus littoralis Grav.).
3. Coleoptera (Beetles) pass
98
through complex metamorphosis,
Dictyoptera (Cockroaches and Man-
tids) through simple metamorphosis,
Phasmids (Stick and Leaf Insects) also
simple metamorphosis and Aphanip-
tera (Fleas) strangely enough pass
through complex metamorphosis.
4. Insects use their antennae mainly
for smelling.
5. Three reasons why centipedes
are not considered to be insects are
(a) because they have far more than
six legs, (b) their bodies are not
divided into three definite parts—
head, thorax and abdomen, (c) they
never have wings.
6. The Glanville Fritillary (Melitaea
cinxia Linn.) is very rare. It is only
found on the Isle of Wight.
7. What have ruby lips to do with
bees and bugs? Nothing now, but |
believe that lipsticks were made out
of bees’ wax and crushed, red
cochineal bugs.
8. You had to draw a Red Admiral
Butterfly for this one.
9. Gynandromorphs are _ really
strange. They are freak animals,
sometimes insects such as moths,
which are half male and half female.
10. Anopheles is the genus (first)
name for a group of mosquitos which
are infamous for spreading the
disease, malaria. You will be sur-
prised to know that at least five
species of Anopheles occur in Britain.
11. Two orders of insects, whose
members are characterised by having
their back legs modified for jumping,
are the Orthoptera (Grasshoppers
and Crickets) and the Aphaniptera
(Fleas).
12. | think it was quite a challenge
to be asked to draw and colour the
caterpillar of the Pale Tussock Moth
(Dasychirae pudibunda Linn.).
13. June or, as they are sometimes
called, May Bugs are, as | am sure you
knew, beetles (Coleoptera). They are
also known as the Common Cock-
chafer (Melolontha melolontha Linn.).
Have any of you seen the large
AUGUST, 1968 |)
numbers of these insects which are |
supposed to be seen commonly all
over England? | haven’t. 7
14. Stone flies are rather ancient
looking creatures belonging to the
order Plecoptera. Their nymphs live
under water, while the adults are
often found doing nothing in particu-
lar except resting on waterside
stones.
I5. Once again you were called
upon to draw and colour an insect.
This time it was the Great Blue
Underwing Moth (Catocala fraxini
Linn.) also known as the Clifden
Nonpareil. It is very large and rare.
l6. In Britain we have seven species
of social wasp all looking at first
glance very much alike. They are the
Common Wasp (Vespa (Vespula) vul-
garis Linn.), German Wasp (V. ger-
manica Fab.), Red Wasp (V. rufa
Linn.) Norwegian Wasp (V. norwegica
Fab.), Tree Wasp (V. sylvestris Scop.)
the parasitic, Austrian Wasp (V.
austriaca Panz.) and last but not least
the Hornet (V. crabro Linn.)
17, Ateuchus sacer Linn. is the Holy
Scarab Beetle which, with cats, was
worshipped by the ancient Egyptians.
[8. A picture of a Water Scorpion |
was required here. |
19. If animals live in symbiosis they |
actually live in co-operation. For) x
example ants obtain sweet fluids
from aphids and in return protect
them from their enemies.
20. Those of you who are helping
the Nature Conservancy with the
National Lepidoptera Recording
Scheme should send your records to
me or, preferably, to the Biological’ .:
Records Centre, Monks Wood)
Experimental Station, Abbots Ripton,
Huntingdon.

was able to show its worth over the
next fortnight on some hazardous
roads covering some 900 miles. Our
first stay was at a small Hotel in the
village of Dongio on the road leading
from Biasca to the Lukmanier (Luco-
magna) Pass. All the passes and many
of the villages have dual names—
Italian and German—which can lead
to some confusion. Not knowing
anything of the area, we were obliged
to sample to find suitable collecting
terrain.
Most of the valley areas are
meadowland and these are rich in
flowers but are regularly cut and
harvested for winter fodder and the
insect population consequently
suffers. However there are still many

more species flying than one would
see in an English meadow and our
first sortie was amongst some of
these meadows just below the village
of Olivoni on the way to the Pass.
The torrent ran below the meadows
which terraced down to it from the
roadway. Grass cutting was in pro-
gress but in the uncut areas of grass,
blue Salvias, Lilies and a host of other
flowers there were flying plenty of
the large Apollo, Parnassius apollo
Linn., the Marbled White, Agapetes
galathea Linn. and the Dark Green
Fritillary, Mesoacidalia charlotta Haw.
There were also a few Black-veined
Whites, Aporia crataegi Linn. about
but these were past their best. The
Dingy Skipper, Erynnis tages Linn.,
was very common and we also took
a few Pyrgus cirsii Rbr. The only Blue
present was the Mazarine, Cyaniris
semiargus Rott., and this was plentiful
in both sexes. In the small wooded
areas near the stream were some
newly emerged Ringlets, Aphantopus
hyperantus Linn., and where the grass
was lying cut in the meadow there
were fresh Meadow Browns, Maniola
jurtina Linn., some of which | collected
for George Thompson of Perth. One
new species for me was the White,
Pieris mannii Mayer, which is very
like the Small White, P. rapae. As
both species fly together it was
difficult to assess how common each
species was. We found the sun very
hot and after a meal we decided to go
up the Pass. After a drive along an
excellent new road climbing up the
pass we reached the old roadway
which is still in the course of being
rebuilt. Here we stopped where the
road passed through a wood of tall
Spruce. Climbing up the slope at the
side of the roadway we found a path
leading out onto some rough mead-
ows through which a small steam
trickled. In the boggy patches were
Cotton Grass and small groups of
orchids and some interesting butter-
flies. The altitude was between 4,000
AUGUST, 1968
and 5,000ft and the spring butterflies —
of England were on the wing in this
first week of July. The Chequered
Skipper, Carterocephalus palaemon
Pall., the Small Pearl-Bordered and
Pearl-Bordered Fritillaries (Clossiana
selene Schiff. and C. euphrosyne Linn.),
the Orange Tip, Anthocaris cardamines
Linn., were flying together with the
later species /Maculinea arion Linn.
and Mellicta athalia Rott. | netted
some of the fatter which laid batches
of eggs for me in pill-boxes having a
leaf of Plantago lanceolata Linn. in
them. This was done while the boxes
stood in the hotel window the next
day. Species new to me here were
the Wall, Dira petropolitana Fab.,
and the very local Fritillary, Clossiana
thore Huebn. This latter insect is of
the shape of C. euphrosyne but the
upper side is heavily suffused with
black and the underside has purple
markings. The only Erebia present,
Erebia ceto Huebn. (=alberganus de
Prun), was just emerging here. On a
small slope by the road there were
several large clumps of Horseshoe
Vetch (Hippocrepis comosa Linn.) and
on these | found two larvae of the
Chalkhill Blue, Lysandra coridon Poda.
They were nearly full fed but later
produced small hymenopterous para-
sites from a mass of white cocoons,
rather like those of Apanteles glomer-
atus Linn.
Later in the week we decided to
try higher up the pass and drove up
near to the top where the pass opens
up and overlooks wide meadows,
fringed on one side by tall Spruce and
on the other by a rocky chaos clothed
in Rhododendron ferrugineum Linn.
The meadow area was reasonably flat
with small streams cutting across it
leaving small bogs and pools. Down
the centre of the plain ran a fairly
large stream coming from the glaciers
in the distance. Heavy grazing had
taken place and there were large
herds of cattle among the trees and
on the slopes around. By the stream

ally on the small flowers growing by

appeared to be about to deposit her
eggs on some plants of Saxifraga

-edge. There were a few Chequered
Skippers about but apart from a few
Pieris bryoniae Ochs. wandering
through the woodland this area was
very short of butterflies. | crossed the
valley and climbed up where the
chaos of rocks formed a rugged wall.
Among the rocks were growing a
little yellow violet, Viola biflora
-Linn., and Primula farinosa Linn. The
only butterflies here were the small
Tortoiseshell, Aglais urticae Linn., and
D. petropolitana. It seemed that we
were perhaps a little early for the
butterflies at this altitude. The area
_would certainly merit a visit a few
weeks later as it is quite wild and
unspoiled apart from the grazing.
_ At the Hotel in the evenings we
spent our time setting the day’s
catch, interrupted by a terrific storm
-each night which filled the mountains
with rolling thunder while the rain
-torrented down the village street.
Sometimes the lights failed and we
could do nothing. Before the storm
one evening | had a look round the
street lights and watched a bat at
_each catching the moths that came
into the light. The only moth which
seemed to be immune was an orange
footman with black spotting which
was all about the hotel walls in the
morning. As these moths flew past
one, they emitted an audible crack-
ling sound and this possible ‘anti-bat’
_ device may have been the reason for
their safety.
"Our next area for collecting was in
a hidden valley near the village of
| Campo Blenio. The valley was reached
| by passing through a mile long
:
|
wate
| tunnel behind the village of Olivoni.
This area was a real find. The stream
10]
ran down through the bottom of the
valley coming from the glacier on the
Piz Medel and the road ran up to the
village of Campo Blenio and a small
roadway off it carried on to the top
of a huge barrage which contained a
vast lake, a source of hydro-electric
power. The whole valley was rich in
flowers and butterflies. The Lycaenids
were well represented and included
the Small Blue, Cupido minimus
Fuessl., the Large Blue, M. arion
Linn., Glaucopsyche alexis Poda.
(rather worn), Lysandra dorylas
Schiff., C. semiargus Rott., and the
rather local Cupido sebrus Huebn. By
the stream side were flying newly
emerged Purple-edged Coppers,
Palaeochrysophanus hippothoe Linn.,
being much larger specimens than
usual for the sub-species eurybia
Ochs. Another Copper flying in the
area was the sub-species of Heodes
tityrus Poda, ssp. subalpina Speyer.
These were newly emerged also and
| took both males and females. They
are both very dark on the upper side
and show no ‘copper’ colouring.
There were large patches of the field
geranium, Geranium sylvaticum Linn.,
and hovering over the flowers was
another Blue, Eumedonia chiron Rott.,
whose larvae feed on the flower and
seed heads of the plant. All the
slopes and meadows abounded in
Erebia ceto Huebn., very large speci-
mens with fine markings. | also took
one male Erebia ligea Linn. Where
one of the streams spilled across the
road there were several Chequered
Skippers settling to sip at the water
and here | also saw the Painted Lady,
Vanessa cardui Linn., the Peacock,
Inachis io Linn., and one Nymphalis
polychloros Linn. The Fritillaries
included Mellicta perthenoides Kef.,
Melitaea diamina Lang, M. didyma
Esp. and Clossiana titania Huebn.
We spent several mornings in this
area as there was plenty of collecting
terrain and the flowers and insects
were profuse. The view of the snow
102
capped mountains at the far end of
the valley tempted Uffen and | to
make the long journey beyond Campo
Blenio to explore the area of perman-
ent snow. One morning we left
Coleridge collecting in the valley,
while we climbed up the winding
pathway which passed first through
flowery meadows and then into a
grassy valley below a waterfall which
came down over the rocks to form
the stream. We found a marked
pathway up the rocky slope and by
this were able to climb above the
drifts of snow and reach the more
rugged ground. Here there were
large clumps of Alpine Dock, Rumex
alpinus Linn., a plant as large as our
Water Dock, Rumex hydrolapathum
Huds. There were drifts of Rhodo-
dendron and plenty of Gentians and
other high alpine flora and Pieris
bryoniae Ochs. was flying every-
where. | netted a specimen of the
high mountain Blue, Albulina orbitulus
de Prun (pheretes Hffsgg), and one or
two Aricia allous G.-H. There were
several of the high-mountain Colias,
C. phicomone Esp., chasing each other
up and down the steep slopes but
giving chase was out of the question.
On one slippery patch where algae
were growing on the wet rock face |
pitched face first and bruised my chin
badly, a warning to watch my step.
The hope that this area might pro-
duce some of the higher level Erebias
was at last realised with the capture
of a male Erebia tyndarus Esp. and |
then took two specimens of Erebia
pandrose Bkh. (lappona Esp.). This is a
very beautiful Erebia rather like a
large E. tyndarus on the wing. | had
taken it previously on the Lautaret
in the French Alps and at Bareges in
the High Pyrenees. These specimens
were perfect and our fears that we
were rather early for butterflies at
the higher altitudes seemed correct.
Some cloud began to obscure the sun
and this quickly puts the Erebias
down so we made our way back
AUGUST, 1968
towards Campo Blenio and the car.
On the way down | had an excellent
view of the Alpine Marmot (Marmota
Marmota Linn.) perched on a huge
rock. He watched me until | was
about thirty yards away and then shot
down under the rock. As | looked
back some fifty yards further down
the hillside | saw him back on his
vantage point and a single scream
from him was echoed by others high
up on the far slopes of the valley. The
only other life in this high valley
were the dry cows and heifers grazing
by the pathside and the solitary):
herdsman and his dog. Raymond
Uffen had taken one specimen of the.
beetle, Emus hirtus Linn., coming tof,

On the day before we left Dongi
we made a special sortie down t

locality for a very local Erebia, E
flavofasciata Heyne. The first half o
the valley was level driving and the
we started to climb beyond Bignasco
The road soon overlooked the gorg
at the bottom of the valley and w
stopped for lunch at a spot where th
road widened. There were raven
nesting on the opposite side of th
ravine and just above the road we
found some little alps hidden by th
roadside trees and bushes. Thes
were alive with butterflies and ther
were fresh specimens of the Coppe
Heodes alciphron Rott. (ssp. gordiu
Sulz.) and badly rubbed Green Hair

of the High Brown Fritillary, Fabri-
ciana adippe Rott. As we drove
further on along the valley the road
began to climb sharply by means of a
series of acute hairpin bends—we
counted thirty-two in all—until at
last we reached the outside of the
village of Fusio. Here we stopped to
explore some small gulleys by the
roadside, full of flowers and lush
grass. The Black-veined White was
very common and in good condition
and there were Erebia ceto, E. euryale,
| and a few E. ligea. A new Erebia to
me, E. medusa Schiff., was also present
in fair numbers but in a very rubbed
state. | also took C. selene and M.
diamina. Unfortunately the sun was
partly shaded and although quite a
lot of butterflies were flying, many
- Lilies and Orchids,
more appeared to be resting and had
to be put up. We drove through the
village of Fusio, perched on the
' mountain side, and then a short way
up the road leading to the great dam
above the village. It was here that we
hoped to find E. flavofasciata but we
only found species which we had
found lower down, although the
flowers were some compensation—
Gentians and
Mountain Asters. By 4 p.m. the sun
had got behind the peaks and we
returned down our thirty-two bends
to the valley and again past the Lake
to Dongio, a round journey of nearly
- 150 miles.
On the day that we left Dongio to
go into North Italy the heavens
opened and we had the only wet day
of our holiday. It poured hard all day
and a heavy mist filled the valleys and
shrouded the lake. Beyond Locarno
we took what appeared to be the
shortest route to Domodossola, over
the mountains via the Cento Valle
road. This proved to be a mistake in
the conditions. Rain and mist made
103
visibility bad and the road wound,
climbed and twisted its way across
the face of the mountains and it was
impossible to hurry. Just beyond the
Italian/Swiss frontier post we nearly
had a collision with a fast moving car
coming round a corner towards us
and in taking avoiding action we
suffered our only mishap, the rear
wheel skidded off the road and the
rim struck a projecting rock giving
us a good jolt and the rim a nice dent.
We tried the villages round Domo-
dossola for a likely hotel but in the
end decided on the Hotel Tronconi,
the only one in the village of Varzo
which had once been on the approach
to the Simplon Pass but now lay ina
back water with the pass lying well
below the village. The hotel was
huge with only a handful of guests
and we were well suited. The village
had seen better days—many of the
gardens had exotic trees and plants
growing in them, mural paintings
decorated many of the walls of the
houses and there were numerous
shrines and chapels of ease, though
only the village church seemed to be
in use. We had the advantage of a
quick route to the mountains and an
equally easy one to the Italian plain.
The following day the weather
returned to brilliant sunshine and we
drove over the Simplon Pass to
Ganter Bridge on the North side
where we had been in 1966. The little
valley beside the bridge is always
alive with butterflies and this morn-
ing was no exception. The Blues,
Lysandra coridon Poda, and L. escheri
Huebn. were newly emerged; the
latter is like a large Common Blue, P.
icarus Rott. There were also several
of the smallest Apollo, P. mnemosyne
Linn., flying but these were in a bad
condition. | was also pleased to find
the small Fritillary, Mellicta aurelia
Nickerl., and the Satyr, Hipparchia
alcyone Schiff., like a small version of
H. fagi Scop. Coleridge and | then
climbed up through some meadows
104
and into a copse of Spruce through
which there ran a wide glade. Very
quickly we found that very local Blue
butterfly, Plebejus pylaon Frhst. which
was flying along the glade, the males
very actively on the wing and the
females on the food plant Astragulus
exscarpus Linn. which grew in tufts
along the path and on the grass edges
of the woodland. We took about half
a dozen specimens in quite good con-
dition. | also netted a specimen of the
small Cicada and photographed a
female Wood White, Leptidea sinapis
Linn., laying her eggs on a species of
Vetch. The sun was very hot and we
were bothered by a very large biting
fly which had one or two goes at my
legs before | netted it. Back by the
stream we found several of the
Spanish Fly beetle, Lytta vesicatoria
Linn., settled on small Alders (Alnus
sp.). There was one pair in copulation,
the male being about half the size of
the female. It is a very beautiful
beetle, being metallic green. | also
took a very fine variety of the Purple
Edged Copper, P. hippothoe, with the
underside spots run into long streaks.
After our meal we drove back to the
top of the Simplon and collected for a
while in the valleys near the Hospice.
| took several specimens of the
Scottish Burnet, Zygaena exulans von
H. and R., and the Fritillary Euphy-
dryas glacigenita Vty, also some newly
emerged males of Erebia epiphron
Knoch. | also saw a passing specimen
of Synchloe callidice Esp. but this
species flies so fast that | failed to net
it. It clouded over and began to rain
a little and not even Uffen’s smoker
would move anything out of the
scrubby undergrowth so we called it
a day and drove back to the frontier
where we changed our Swiss Francs
for Lira and returned to the hotel for
some setting and dinner.

LUCANUS CERVUS Linn.
(MALE)
This is perhaps one of the most
well known of all British insects.
Instantly recognisable because of its
size and formidabie looking jaws—
which are capable of giving a very
firm nip. During warm evenings in-
late May and June the Stag Beetles |
can be seen crawling about or flying —
in an almost upright position; they —
are also attracted to light, like most
scarabid beetles.
The female is similar in size and
shape to the male but does not
possess the large head and man-
dibles.
For an account of the distribution
of this species one should read the
excellent paper by D. G. Hail
‘Distribution of the Stag Beetle in
Britain.” |
The larvae take three or four years,
to reach maturity and can be found:
in the roots and trunks of certain)
rotting hardwood trees. |

ants
from close up
by L. HUGH NEWMAN
photographs by STEPHEN DALTON
In this superb book the ant world in all its variety is revealed
in highly readable text and superb, unusually detailed
photographs, showing ants at work, at war, and at play.
Author and photographer, experts in the field of insect
behaviour and photography, stress the great strides made
in our knowledge of ant life during the last decade.
__ Mr. Newman compares ants and their habits to other
insects, describes their anatomy and their development
_ from egg to adult, and follows the growth of “ant cities’,
starting with the queen’s migration to a new nest site. He
tells how ants find their way about, recognise one another,
and distribute their work and food: and he shows how
~ “social hormones” or pheromones regulate ant society,
centred upon the queen.
Among the many kinds of ants presented i in words and
: pictures are harvester ants, “cattle-herding” ants, slave-
owning, warrior and parasitic ants, arboreal ants, weaver
ants, and wood and honey ants——whose “repletes”, or
Jive-ant storage vessels, full of liquid, may hang patiently
for months from the ceiling of their nest. A most remarkable
series of pictures show an ant being attacked and eaten by
a preying mantis.
The three ant types that have virtually colonised the
- globe—the Argentine ant, Pharoah’s ant, and the common
_ house ant—are fully described, as well as the all-devouring
oe _ African driver ant.

AES BULLETIN, VOL. 27
| have noticed that several of my
friends, who in most respects have
comprehensive collections of the
smaller moths, possess relatively few
of the Lithocolletidae. This is due to
neglect, because most of the species
in this group are widely distributed,
readily found and easy to breed.
Since the larvae pupate in their
mines, the precise date for the
collection of the autumn brood is not
critical. November is not too late to
collect a great many of the fifty
species. It is generally easier to find
the mined leaves while they are still
on the tree, but fallen leaves contain-
ing larvae are sometimes conspicuous
through the area of the mine retain-
ing its green colour after the rest of
the leaf has turned.
The wild imagines emerge in late
April or May, but if the mines are
‘kept out of doors until the end of
January and then brought into a
‘warm room, the moths will soon
come out, thus providing entomo-
logical activity in the fallow months
of the year.
| propose to deal in this article
with the oak-feeders, since oak leaves
fall late, and the mines may be
collected till the end of November or
later. There are nine species, two of
which are very common, and, |
believe, ubiquitous. These are Litho-
colletis quercifoliella Zell. and L.
harrisella Linn. (cramerella Fab.). To
these | might add L. messaniella Zell.
which feeds on the deciduous oak as
well as the Holm Oak (Quercus ilex
Linn.) though it has a preference for
the latter. Two other species are less
common, but | have been able to find
them whenever | wished in the south
of England. The first is L. heegeriella
Zell., which makes a small mine
usually under a lobe of the leaf. The
other is the beautiful L. /autella Zell.,
which seems to be confined to the
Durmast or Sessile Oak (Quercus
petraea Liebl.); this species of oak
may be distinguished by the leaves
107
which taper without auricles or lobes
on to rather longer stalks. L. Iautella
prefers saplings or low bushes; |
once found it plentifully in the shoots
springing up round the stump of a
felled tree. | have yet to encounter
the other four species. L. roboris Zell.
is very local but has a wide range.
L. distentella Zell. seems to be pre-
dominantly a moth of the Midlands,
though | have been told that it has
been taken in Kent. The West
Midlands, too, are the headquarters
of L. amyotella Dup., which is reputed
to feed in the topmost leaves of tall
trees. The best chance of obtaining it,
therefore, is to search for mines
among fallen leaves in mid-winter.
The last species, L. hortella Fab., has
a fairly wide range in the south of
England, but seems to be far from
common; like L. Iautella, it is said to
prefer the Durmast Oak.
The best chance, then, of obtaining
the rarer species is to collect mines
from different species of oak growing
in varied situations and to include a
proportion contained in fallen leaves.
The mines should be kept out of
doors in linen bags, or spread on
earth in seed-boxes. lf you adopt the
latter method, a lid is necessary to
prevent the leaves from blowing
away. | use another seed-box, raised
on slats to allow ventilation and
weighted down with a brick; this
method has proved very successful.

Hymenoptera Aculeata
The Hymenoptera number many,
in fact a majority of, parasitic species
among their ranks, and equally they
are subject to parasitism. Among the
Aculeata, many species have devel-
oped a specialised form of parasitism
which they practise on species
related, often closely, to themselves.
These are the so-called inquiline, or
cuckoo, species. Other insects also
make use of the stores of animal or
108
plant food laid up by Aculeates,
either directly or by eating the
hymenopteran larva when it has
developed. Fewer are endoparasitic
on the hymenopteran larva and yet
fail to kill it and are carried over into
the adult. One particularly fascinating
group in this last category are the
forms commonly called Stylops.
This group has a particular interest
for British entomologists as a male
Stylops appears in the seal of the
Royal Entomological Society of
London. It was the Rev. William
Kirby who first described the Strep-
siptera, the order erected to contain
Stylops and its relatives. He was also
the first Honorary President of the
Society and is one of the people best
qualified to receive the title ‘‘Father
of British Entomology.’’ When in
1932 the Society commenced a serial
publication for taxonomic work they
named it ‘Stylops’ and so it appeared
for four years, after which it became
the Proceedings Series B, Taxonomy,
that we know today. To carry the
association to its most recent mani-
festation, a male Stylops was chosen
as the Congress crest for the [2th
International Congress of Entomology
held in London in 1964.
So much for associations, now for
the actual insect. Stylops are best
known in this country as parasites of
bees of the genera Halictus and
Andrena. The female parasite can be
seen as a light brown head protruding
from beneath the hinder abdominal
tergites of the host. She is reduced to
little more than a sack of eggs within
the host body which she never
leaves. The male Stylops is a free
flying insect that emerges from the
body of the host leaving a gaping
hole. Several parasites can develop
within one host and | recently saw a
female Andrena helvola (Linn.) taken

much discussion, which is hardly):
NOVEMBER, 1968) >i:

The life cycle of the parasite is mos
interesting. The male fertilises th
female while she is in the host. Th
eggs hatch within the body of the
female and emerge as active triungu-
lin larvae similar to those of the
beetle family Meloidae. These larvae
presumably move onto the flowers
visited by their host to pass onto
fresh hosts and are thus carried back
to new nests where they enter the
bee larva when it develops. Members)
of the Stylopoidea attack not only
bees but also solitary and social
wasps, and outside the Hymenoptera):
certain Homoptera Auchenorrhyn-
cha, particularly of the familyl:
Delphacidae.
The taxonomic position of the}!
Stylopoidea has been the subject of
surprising in a group so_ highlyy:
modified for its parasitic mode of
life. The two common courses are toj})
place the group in a separate order,
the Strepsiptera (Imms, 1957) or as a
superfamily within the Coleoptera
Polyphaga (Crowson, 1956). This)"
latter course is further argued by|)"
Crowson (1960). The extremel ,
reduction of the fore wings of the
male Stylops to haltere-like structures
is certainly not appreciably more
extreme than the reduction of the
elytra in the beetle Atractocerus
brevicornis (Linn.) which | have taken
at light in Rhodesia.
Imms (1957) includes an excellent,
concise account of the group with
ample reference to the available
literature. This is not extensive, and
little attention has been paid to
Stylops, at least in this country, for) \:
many years. This is where AES
members can help. Mr Bruce Ing is at
present working on the group with aj,
view to bringing out a part in the
series of Handbooks for the Identi-
fication of British Insects published by
the Royal Entomological Society. The
occurence of Stylops in bees is very
rarely noted in the literature, and |

It is a pity more notice has not
been taken of stylopised specimens
if only because the presence of the
parasite alters not only the physiology
but also the morphology of the host.
Thus stylopised specimens can be
difficult to identify. The changes
have one particularly fascinating
aspect. The tendency is for both
sexes to lose the particular adapta-
tions typical of their sex. Thus females
may have reduced pollen collecting
apparatus and males in, for instance,
species which normally have a yellow
clypeus, may have the extent of the
yellow reduced.

OBSERVATIONS ON
BREEDING
CLEPSIS COSTANA FAB.
During the early part of May 1965 |
collected some Clepsis costana Fab.
larvae from Willowherb (Epilobium
sp.) at Dovedale on the Derbyshire/
Staffordshire border. The larvae were
of a similar shape to those of Olethreu-
tes lacunana Dup., but the colour was
a dark chocolate brown, with spots
and the spiracular lines a pale brown
to whitish. | took these larvae home
to St Austell, Cornwall and for con-
venience changed the food-plant to a
different species of Epilobium. The
whitish spots became less distinct as
109
the larvae reached maturity. Some of
the larvae produced, in due course,
hymenopterous parasites and died,
but about a dozen others duly
pupated and produced imagines in
June 1965. All except two of the
moths were more or less of the
normal colour and size and looked
like the illustration published in the
Bulletin (Bull. amat. Ent. Soc. 27: 39).
Of the remaining two, one was
melanic with the whole of the fore-
wings a greyish black colour obscuring
the normal markings (the hind-wings
being only slightly greyer than nor-
mal). The other moth appeared to be
about halfway between the melanic
and the normal forms. Several
matings of the typical moths were
obtained and the imagines of the
next generation emerged in August
1965. These imagines (a total of about
twenty to thirty) were smaller than
usual for C. costana—and every
single one was melanic! These also
mated, and many of the surplus
larvae were released on Willowherb
in my garden in September/October
1965, to give them a chance to
hibernate in natural conditions.
Unfortunately the larvae which |
retained in captivity all perished due
to unknown causes during the winter.
Had | been able to continue the
breeding experiments of 1965-6
through further generations | would
have been able to discover whether
the melanism was genetic in origin or
whether it is connected with small-
ness and a life cycle of less than the
normal twelve months. In the absence
of further evidence | would prefer to
compare the melanism in C. costana
with the colour differences between
the first and second broods of Selenia
bilunaria Esp. than with the dominant
genetic melanics of such species
Biston betularia Linn.
In February and March 1966 |
searched in my Willowherb for the
overwintered larvae which | had
released the previous autumn, and
110
was able to find only one larva which
eventually produced a moth of the
normal, typical form in June 1966.
One night in May 1966 | was trying
to assemble a male Eulia ministrana
Linn. to a freshly emerged female of
that species in my assembling cage.
On looking into the cage the follow-
ing morning | found not a male E.
ministrana but a male melanic (!) C.
costana in the cage with my female
E. ministrana, which subsequently
laid eggs that proved to be infertile.
| do not know whether copulation
had actually taken place, but | have no
doubt that this assembled male C.
costana was from one of the larvae |
had released earlier.
On looking at the specimens of C.
costangd in the _ British Museum
(Natural History) collection in
London in October 1966 | noticed
that nearly all seemed to be of the
normal form, and only two or three
melanic. In the published literature
(Ford 1949) it is stated that C. costana
has only one generation per year, but
in my experience of this species in
captivity there are two generations
per year. | would be very interested
to know whether anyone else, with
experience of breeding C. costana,
could supply answers to the following
questions (either to me personally,
or in the Bulletin):
|. Does C. costana always produce
only one generation per year in a
state of nature?
2. When second broods of C.
costana are raised in captivity are
they always small and melanic?
3. In the Tortricidae, is it usual
for female scent of one species to be
attractive to a male of another
species?
4. Are there any known cases of
hybridisation in nature among the
Tortricidae?

NOTES ON BREEDING
ZYGAENA CARNIOLICA
SCOP.
The burnet moth Zygaenda carnio-
lica Scop. is widely distributed in
Central and Southern Europe, North
Africa and Western Asia. This attrac-
tive species is often abundant in its
flight places, and this together with
the great variation in markings from
one specimen to another, has caused
the species to be much studied.
During the third week of August
1967 a number of worn female moths
were collected in late afternoon from
screes on the south side of Col
d’Ornon near Entraigues some fifty
km southeast of Grenoble, France.
The locality was a narrow defile with
a road and fast flowing stream at the
bottom. The sun had almost left the
lower slopes and the only Lepidop-
tera still flying were these Burnets.
Several individuals were often seen
on the same thistle flower jostling for
the best position. Capture was easy
and the females were placed in a
small jar with some leaves of Dory-
cnium sp. Ova were laid almost
immediately on the leaves and the
walls of the container. They were
similar in colour to those of Z.
lonicerae Esp. (Narrow-bordered
Five-spot Burnet) but slightly smaller
and laid in groups of six or so. Z.
lonicerae lays very large batches of ova
in captivity as well as smaller groups
scattered around the cage.
On returning to England the ova
were kept in a warm room and
hatched in nine days. The larvae were
very dark—much darker than those
of Z. lonicerae for example. Seitz
(1913) mentions Hedysarum, Dory-
cnium and Astragalus as foodplants
and Kirby gives Astragalus glycyphyllos
Linn. (Milk Vetch, Wild Liquorice)
and Onobrychis sativa Lam., (=O.
viciifolia Scop.) (Sainfoin). The trefoils
(Lotus sp.) are not specifically men-
tioned as foodplants, however the

young larvae took readily to Lotus
corniculatus Linn. (Bird’s-foot Trefoil),
but grew very slowly and once in the
second instar became torpid. They
were then transferred to a cold room
at 4°C and left there for almost seven
months until the middle of April 1968.
On placing on trefoil growing in a pot
they underwent a further ecdysis and
commenced feeding, to reach matur-
ity by mid May. The full grown larva
is slightly smaller than that of Z.
lonicerae and with similar markings
along the back except that the second
Spot on each segment is grey rather
than black. The ground colour is
bluish-green. Laterally are a series of
yellow spots and below these U-
shaped grey areas. Anteriorly these
grey markings form two distinctive
circles on the thoracic segments.
At each ecdysis a large silken pad
was constructed on which the larvae
hung downwards for several days
before effecting the skin change. The
ovate cocoon was constructed on
grass stems provided and was con-
siderably smaller than that of Z.
lonicerae. It was white with the
appearance of unglazed porcelain and
free of the folds seen in the cocoons
of many other Zygaenidae. The gen-
eral shape and smooth outline made
the cocoon closer to the form found
in the Eggar moths than to Z. loni-
cerae or similar burnets. Due to the
well-rounded appearance of the
cocoon the area of attachment to the
stem was small, and “‘hold-fasts’’ of
thick silk strands anchored both top
and bottom.
The pupal stage lasted about ten
days. The adult is most striking with
red spots centred in yellow rings.
The antennae are strongly clubbed.
The thorax is predominantly blue-
black with some white hairs, and in
addition two longitudinal and one
transverse streak of white. The black
abdominal segments are fringed in

blue hairs. The red hind wings are
fringed in a narrow black band of

The name-typical form of Z. carnio-
lica has a red band on the abdomen.
The form described here seems to
come close to the description of
aberration hedysari Huebn. figured in

The genus Orthosia (Noctuidae)
commonly known as Quaker moths,
consists of nine British species though
this study only covers six in some
detail. All these species have a wide
distribution in Britain and where
they occur are usually common.
Over a four year period the domin-
ant species was undoubtably O.
gothica Linn. (Hebrew Character). It
always emerged first, often a week or
so before the rest, and appeared
regularly in the trap till early June
shortly after the other species with
the exception of O. incerta Hufn.
(Clouded Drab) had finished. The
chart showing the flight periods
(fig. |) has been based upon the size
of daily catches and not population
estimates by marking or similar
methods.
During the early stages of emer-
gence of at least four species there
appeared to be a low percentage of
females (fig. 2). This could be accoun-
ted for by the earlier emergence

and flight of males possibly in seeking
their mates. After mating, active
females would then, perhaps, alter
their flight behaviour to coincide
with a maturing and ovipositional
process and so become more attrac-
ted to food rather than light sources
and so avoid capture. Then again
females by their nature of being
heavier than males could have a
reduced flying range and so appear
less frequently in the trap.
The interpretation of insect flight
response to air temperature has
recently been reviewed in an article
by Taylor (1963). The major difficulty
of separating temperature effects on
a fluctuating population and those of
pure flight response were overcome
by plotting the response at a parti-
cular temperature as either | or 0
depending on the presence or absence
of individuals and not their numbers.
In O. gothica the difference between
these two approaches (fig. 5a and b)
is not entirely obvious but it can be
seen that the second is of more direct
use. For instance the lower and upper
temperature thresholds can easily be
defined as the temperature at which
there is a 50% flight response by the
insect. In the case of O. gothica the
lower threshold would be 43.5 °F. for
the males and 45.0°F. for the females.
The upper values would be 56.0°F.
and 57.0°F. respectively. In general
females preferred warmer conditions
than their male counterparts and the
similarity of their temperature ranges
can be seen in fig. 4.
All six species showed a similar
pattern in their behaviour to wind
force (figs. 6 and 7) as they preferred
a slight breeze (force 2) in contrast to
still weather. Further increases in
wind force tended to reduce the
flying population especially those of
the female. O incerta and O. gothica
were extremely wind tolerant and
occurred frequently in the trap
whereas O. gracilis Schiff. (Powdered
Quaker) with a limited resistance
appeared on a few isolated occasions.
It would be reasonable to assume that
the ability to withstand windy con-
ditions is of some importance in this
genus in controlling their flying
popuiations.
O. incerta has a wide range of colour
variation but can be divided into
three distinct groups, those with
light grey, brown or dark grey fore-
wings. Moths with dark forewings
represented 50% of those caught in
the trap, while brown and light grey
specimens formed 41% and 9% of the
total respectively. The light grey
form occurred at a low level through-

to reach its peak definitely before the
other two. Although colour followed
a light to dark sequence it could not |
be proved that the two later forms |
had separate peaks. |
In conclusion the six species of |
Orthosia show a great similarity in |
their range of responses to tempera- |
ture and wind. These responses have
been shown to differ slightly in the |
two sexes, females preferring warmer
and less windy conditions. The early
appearance of a light grey O. incerta |
cannot be explained yet and further
work will be needed to solve this |
problem. A possible interesting line |
of approach would be to carry out |
simultaneously, an identical study of |
these insects at sallow blossom and
compare this with samples obtained
from the light trap.

the arable land, this area is mainly
forested. The dominant tree is spruce
(Picea sp.), but notice the predomin-
ance of pine (Pinus sylvestris Linn.)
along the lake-shore. The few small
swamps are dominated by stunted
pine trees and are enclosed mainly by
spruce forest.
Area F. 9 km. from Tampere: this
is the “‘lantern-fly-shaped’’ peninsula
immediately to the south of area E.
The wilder part of it consists of
spruce-dominant forest with Vaccin-
ium vitis-idaea Linn., but there are
also rocky outcrops with pine and
V. myrtillus Linn. During hot weather
the forest is cool and damp, whilst
the rocky terrain is hot and dry. The
area was especially rich in butterflies,
largely owing to the presence of
unkempt borders to the cultivated
land, and to the pipe-line and the
dirt road running roughly east, both
of which have borders on to which
the spruce has not been allowed to
grow.
Area G. || km. from Tampere: a
tract of sandy heathland, with stunted
pine, Erica and Calluna_ species,
extending between the crests of two
steep, pine forested ridges. It was
visited once (June 7th), when the
habitat was hot and very dry (c.f. the
pine swamps, where the air almost
always feels humid).
Area H. 13 km. from Tampere: the
spruce forest between E and H
yielded few butterflies. The north-

Methods. Few specimens of any
species were collected (average
three). Those that were collected
have been provided with a pair of
data labels. Examples are: (i) Suomi-

metre square): Pine-bog.
A rough estimate of the number of
specimens observed was made each
day before leaving the field. These
numbers appear in Table |. This
system dispenses with the inaccurate
‘common — quite common — fairly
abundant’’ categorisation, but there
are, of course, many sound arguments
against its efficacy as an actual indica-
tor of the size of imaginal populations.
As to how far its results reflect com-
parative numbers | have at this stage
no means of knowing.
Early stages. A later account will
deal with the breeding of C. rubi
(from wild collected ova) and P.
hippothoe (from wild collected larvae).
On June 6th a small, spindly bush of
the Rhamnus genus was examined. It
was growing in an isolated position
in a clearing of Pine-spruce heathland
NOVEMBER, 1968
(Area F), and had twenty-eight leaves.
Three G. rhamni ova were discovered
on one leaf (one orange, two white
eggs) and as the one ovum hatched
three days before the others, it
probably came from a different
female. No further bushes were
discovered, despite a diligent search,
and the clearing was gloomy and
well-screened by saplings and mature
trees. A. urticae larvae were found
feeding on Urtica sp. in a birch copse
in Area F. L. sinapis females were
commonly observed ovipositing on
Lathyrus pratensis Linn. in small glades
in spruce forest (Area F). Individual
larvae of C. euphrosyne (May 28th: F)
and C. selene (June ||Ith: H) were
found feeding on Viola canina Linn.
A single pupa of B. ino was collected
by a young friend from beneath a
window-ledge of the summer-house
in Area K.
Distribution. After examination of
field notes, six main habitats were
recognised. Table 2 presents a sum-
mary of the observed preferences of
the imagines for particular habitats.
Because of the small number of
samples counted and of the short
duration of the project, it is obviously
impossible to draw any definite con-
clusions. There are, however, certain
‘pointers,’ some of which will now
be considered.
Conclusions. The first three habitat
types (left to right) in the columns of
Table 2 tend to adjoin each other.
One would expect, therefore, to
discover that there are species which
are commonly found on the wing in
two, or even three, of them: this, in
fact shows up in the table, in the
second horizontal column, for
example. Heathland types and
swamps, on the other hand, are often
isolated (e.g. vegetatively) from their
surroundings. This is particularly true
of the pine swamps, the typical species
of which (e.g. E. embla, C. palaeno,
B. arsilache) are not often found far
beyond the natural limits of their
AES BULLETIN, VOL. 27
habitat. A second group of swamp-
inhabiting butterflies (e.g. C. euphro-
syne, V. optilete, P. argus) is not so
restricted. Species of this group tend
to have a distribution theoretically
_ continuous throughout swamp, forest
and heathland habitats where an
alternative foodplant grows in suffici-
ent abundance to support breeding
populations and where other factors
are favourable to their existence.
With G. rhamni a slightly different
“set of factors seems to be in control.
Firstly, the foodplant (Frangula alnus
~Mill and Rhamnus carthartica Linn.)
'tends to grow in small pockets in a
variety of situations in which only a
damp, humic substratum appears to
be a common factor (there is a grove
-at the lake edge in Area H, several
bushes along the Viitanen cart track,
and an isolated bush in Area F,
-mentioned under ‘‘Early stages’’).
-G. rhamni is a proven vagrant, a habit
possibly correlated with this ‘unreli-
able’ distribution of its foodplant. It
also hibernates as an adult, though
_under what circumstances in Finland
I do not yet know (Ivy does not grow
wild here). These two habits are
_ probably sufficient to account for its
being met with largely as isolated
individuals. When, and under what
circumstances, does pairing take
| place?
Again on the subject of pine
swamps, it is interesting to note that
(after Seppanen and Gullander)
Vaccinium uliginosum Linn. is a com-
-monly-chosen foodplant (C. palaeno,
_V. optilete, P. argus, L. idas, P. eunomia,
C. euphrosyne, C. freija: in the north
» also E. iduna). It grows in swamps in
‘the south, and no certain heathlands
_ in the north, and is found throughout
the country. It is a small bush with
soft green leaves and pendant pink
flowers: there is the facies of V.
_myrtillus or V. vitis-idaea, but V.
- uliginosum is usually much larger than
either of these relatives.
In South-Hame spruce-dominant
[27
forests account for 30-409% of the
total area of productive forest land,
whilst pine-dominant forests amount
to about 40-509 (Atlas of Finland).
The maps show that in Areas E and F
the percentage of spruce-dominant
forest is, in fact, much higher than
40%. Climatic considerations aside,
it could be predicted that the butter-
fly species which had adapted itself to
the Spruce-Whortleberry/Bilberry
(Picea-Vaccinium vitis-idaea/V. myrtil-
lus) habitat would, in the absence of
effective predator and _ parasite
control, be present in the highest
numbers. This is substantiated by the
results obtained thus far. The
numbers quoted for C. rubi are
positively well below the actual
population numbers, and it is hoped
to demonstrate this during the spring
of 1968. There does not appear to be
an unusually high number of tits,
warblers and other insectivorous
birds in these areas and the foodplant
(V. myrtillus according to most books;
V. vitis-idaea according to my own
observations in Area F on May 28th)
grows so profusely that competition
from a number of moth and beetle
larvae is unlikely to exert any great
control on C. rubi populations.
Nothing is known at this stage about
its parasites. On the other hand,
four third-stage larvae of P. hippothoe
collected from Area H on June I Ith
produced one hymenopterous para-
site each, indicating that parasitic
control is to be taken into account
when examining populations of this
species. Again, one male specimen of
L. argiolus (collected Area F, May 21st)
bears the marks of an attack by a bird.
Species which are adapted to
‘gloomy’ mature forest are very few:
P. aegeria and E. ligea, which were
found as isolated individuals (of a
damp stream bank in Kuusamo,
where seven E. ligea were counted in
the course of a half-hour).
Finland has a vast number of very
small farms, each consisting of a few
128
fields and a few score hectares of
forest, from which, with the assis-
tance of the State, the farmers eke
Out a meagre existence. Insecticides,
which are costly, are not in frequent
use on these small farms, and there is
a tendency for small, cleared areas of
forest to be left fallow in order to
concentrate efforts on larger, more
productive parts of the homestead.
Such small, unkempt places in areas
F and H support a large number of
butterfly species. Most of these are
typical wayside insects, but forests
species such as C. euphrosyne and C.
selene are frequent visitors. The
prolificity of flowering herbs, as well
as the comparatively high light inten-
sity, is an attractive feature. On July
7th at the western edge of the field
in Area F many plants were in flower
(see Table 3). Butterflies which were
observed on the wing in that place
are listed under ‘Cultivated land’. On
the evening of July 7th seven of these
species (A. allous, E. chiron, C. semi-
argus, L. amandus, C. pamphilus, O.
venata, C. selene) as well as a number
of different types of Geometrid moths
were found resting on, or near, the
flowers, indicating a well-represented
‘indigenous’ butterfly population.
Vagrancy. The term vagrant as used
in Table 2 is applied to butterflies
which when noted were obviously en
route for some other place. The first
specimen of N. antiopa was observed
flying round a woodyard on the
northern limit of Tampere. The
indication is that it had hibernated in
the immediate vicinity. The second
specimen was flying high in the sort
of country the Finns term ‘‘wilder-
ness’’. Because of the necessity of
seeking out favourable quarters for
hibernation, A. urticae might also be
suitably fitted into this category. Its
case, however, differs from that of
G. rhamni in that, once it has re-
dispersed after hibernation, — it
exhibits a marked tendency to associ-
ate itself for quite long periods with
NOVEMBER, 1968
one particular area.

The ‘Plebejid’ butterflies. Difficul- )
ties were experienced at that time
with identifying butterflies of the/:
Plebejus-Lycaeides-Vacciining type in
the field. They have been included
together in the tables for the sake of
completeness, but nothing more will’
be said about them at this stage.
‘Notes-lV’ will contain
details of the life-history of C. rubi,
and of breeding P. hippothoe.

Our next trip from Varzo was
again up the Simplon road to the
valley of the Laquintal just above the
village of Gabi (just in Switzerland).
This valley has a raging torrent in the
bottom of the gorge and above, the
slopes are partly cloaked by Spruce
and long rivulets of stone streak down
from the heights above towards the
valley. Short grasses and a myriad of
flowers grow under the trees and
BES DUEEETIN, VOL. 27
beside the stone chutes and the
»whole area is alive with butterflies.
This is a famous spot for the Erebia
~species and the only area in which
Erebia christi Ratz. is known to live.
Along the edge of the stream | took
Parnassius phoebus Fab. and one P.
mnemosyne and P. apollo was quite
common. The commonest Erebia on
‘the wing was Erebia ceto and there
were also a few E. euryale Esp. and E.
-melampus Fuessl. along the slopes.
‘Also quite common was a very fine
‘form of Maculinea arion, very large
sand heavily suffused with black
scaling. | took several P. bryoniae and
‘the Fritillary, Mellitaea diamina Lang.
‘Higher up the slope there ran a path
\leading up towards the glacier from
\which the stream sprang. This proved
ito be the most fruitful area and |
ccaptured my first E. christi. It is very
‘like E. epiphron and E. melampus
»when on the wing and also is easily
«confused with Erebia mnestra Huebn.
swhich was flying everywhere over
ithe rocks. Every specimen had to be
‘netted in order to make identity
‘certain and | caught several hundred
specimens to produce five males and
itwo females of E. christi. It is obviously
‘scarce although it has quite a large
area in which it can fly and collecting
is confined to the paths as the slopes
sare extremely steep. One of the
y reasons for its scarcity may be over-
‘collection. That morning we met
Messrs Bretherton and De Worms
vand five other collectors, German,
‘Italian, French and Swiss—more
lepidopterists in one morning than |
‘have seen abroad in six sorties.
‘Erebia christi was the quarry that had
eattracted them. The butterfly is very
similar to E. epiphron which flies in
‘this area and which is larger and
-better marked than E. epiphron taken
vat the top of the Simplon. This led to
“some confusion at first but once | had
»ascertained the characteristics of the
itwo species | was able to pick them
cout quickly. Other Erebia species
[29
here were E. triarius de Prun. (almost
over), Erebia montanus de Prun.
(freshly emerged) and E. tyndarus
Esp. also just emerging, as | only took
males. Another exciting find here
was Colias palaeno Linn. which | was
able to photograph for the first
time. The larvae feed on Vaccinium
spp. There were several of the
Skipper, Spialia sertorius Hffsgg.,
along the path and Uffen had an
interesting morning working over a
pile of cut logs which had both Rhyssa
and Urocerus spp. emerging. That
evening after we had returned to the
Hotel, Uffen remained in the valley
and had an eventful hour with the
microlepidoptera which became
active as the light began to go.
We spent one further day in the
Laquintal and added the Blue, Macu-
linea alcon Schiff., to our score. This
butterfly is very like the Large Blue
in its life nistory as it is symbiotic
with the Ants (Myrmica spp.) but its
plant food consists of species of
Gentians (Gentiana). | also took a
male of this species on the top of the
Simplon Pass flying with some of the
high mountain Colias, C. phicomone
Esp. On this visit we met two Swiss
lepidopterists, one French and one
Italian and again our friends Brether-
ton and De Worms who had been
trying lower down in the Gorge near
Gondo, with little success.
On one afternoon after returning
from the Simplon, Uffen and | spent
a few hours in the fields just below
the village of Varzo, near to a railway
embankment. Here it was parched
and the sun very hot and the insects
quite different from higher up the
Pass. | took F. adippe Rott. (typical
form), C. eupnrosyne Linn., H. alci-
phron Rott., C. croceus Fourcr., A.
galathea Linn. and the Skipper,
Heteropterus morpheus Pall., a species
which | had taken previously in the
Landes, S. France. It has a very distinc-
tive flight and we later found it in all
the wooded areas of the lowlands
130
around Domodossola. | also found
several of the Burnet-like moth,
Syntomis phegea Linn., several in
copula. Another find was a small
species of the Ant Lion Myrmeleon sp.
and a full fed larva of the Pale Tussock,
Dasychira pudibunda Linn. One further
outing in the Simplon area finished
up in the valley above the village of
Simplon Dorf. This was quite a
delightful spot with a racing brook
running through meadows of cotton-
grass and alpine flowers with rocks
and boulders liberally strewn about.
Some new species were found here—
the mountain Fritillary Boloria pales
Schiff., the high mountain Blue,
Agriades glandon de Prun., and Aricia
allous G.H. | was also pleased to
capture a further specimen of Erebia
christi Ratz. being some distance from
the other locality where we had
found it. This is a vast area for
collecting and we had only time to
sample the road fringes and the
small valleys near to the paths. One
could spend weeks here and still
leave much ground untouched.
Beetles were quite plentiful and |
was able to collect several tubes full
for my father. These were later
shown at the Annual Exhibition.
With the continuing hot weather
we now turned our attention to the
lowlands below the Simplon Pass and
beyond Domodossola. The towns in
the area are not very large and
between them and along all the
roadsides lie meadows thick with
flowers. These meadows are cut for
fodder but at this time of the year
cutting had only just started and the
meadows were alive with butterflies.
The river running down the valley
is called the Toce and this opens out
into a very large river beyond the
town of Vogogna. Near this town we
made our first stop by a roadside
stoneyard where they were cutting
granite slabs taken from the moun-
tainside above the valley. The morn-
ing sun was already very hot and the
NOVEMBER, 1968
meadows were thick with a tall
umbelliferous plant which was the
target of most of the butterflies on
the wing. The S lver-washed Fritillary,
Argynnis paphia Linn. was every-
where, freshly emerged. The males
were typical but all the females were
of the form valesina Esp. | captured
some of these alive and was able to
get them home alive to lay eggs in a
cage in my garden. A great thrill was
to take the White Admiral like
butterfly, Neptis rivularis Scop.
(lucilla Schiff.). This flies just like
Limentis camilla Linn. and as both
species were on the wing several
hectic chases resulted in a capture of
the latter. A surprising find was the
second brood of the Duke of Bur-
gundy Fritillary, Nemeobius lucina
Linn. They were all males and very
fresh—we found them later on near
Lake Orta much farther south.
Another new species was Scolitan-
tides orion Pall., a pretty Blue which
haunted one corner of the meadow
where its food plant was growing
(Sedum sp.). H. morpheus was quite
common on the edge of the wooded
slope and also there were a few
Hipparchia fagi Scop., Minois dryas
Scop. Aphantopus hyperantus Linn. An
interesting moth capture was the
Scarlet Tiger, Panaxia dominula Linn.,
flying in the meadow in the bright
sun. We spent two mornings in these
meadows and then made a further
trip on to Lake Orta. This is a much
smaller lake than Maggiore and has a
delightful little island crammed with
buildings. Coleridge had stayed here
on an earlier visit to Italy and we
stopped on the roadway above the
Lake to take photographs. The whole
area leading to the lake and surround-
ing it is heavily wooded and we drove
through densely wooded valleys and
climbed up winding roads edged with
Sweet Chestnut, Oak and Ash to
stop by the roadside for a meal in a
small clearing in the all pervading
forest. Again the Skipper H. morpheus
fees BULLETIN, VOL. 27
was flying in the clearing and a few
| Duke of Burgundy Fritillaries—a
thrill was to find the wild Gladiolus
_ growing near a small brook which
_ ran across the clearing. The Dark
| Green Fritillaries here were very
| large and heavily marked on the
| underside with silver and the High
| Brown Fritillaries included a high
| percentage of the form ‘cleodoxa’.
| We saw three more N. rivularis
flying along the roadside and managed
to net two. The larvae feed on
| Spiraea sp. which was growing in
| clumps here and there in the clear-
| ings. | watched two freshly emerged
| Brimstones, Gonepteryx rhamni Linn.,
| in a courting flight with the male
) eventually §copulating—confirming
} that in this southern region the
| butterfly is almost certainly double
| brooded. We came back via Omegna
| and stopped again in the flowery
| meadows near Vogogna where |
»netted a damaged female Camber-
» well Beauty, Vanessa antiopa Linn. As
it was otherwise fresh | kept it alive
} and brought it back to England with
-me but it died without laying. Dis-
| section showed the eggs to be only
_ slightly developed so it must have
| been a newly emerged specimen
-which had been damaged soon after
-emergence. A surprise here was to
| find the Small Pearl Bordered Fritill-
ary, (C. selene), freshly emerged and
'in numbers—this must be near its
| southern limit. | also caught two
j very brightly coloured specimens of
} the Copper, Heodes tityrus Poda,
| (both females). They contrast dram-
-atically with the females of the sub-
species subalpina Speyer which we
-had taken on the Simplon. These
| meadows were so full of insect life
“that the time was again too short to
_take in all that was there. The trees
| were buzzing with Cicadas and | saw
‘a large snake curled up by some
“rocks but it was too quickly away to
Videntify. On the cliffs above the
valley we spotted a pair of eagles
13]
wheeling and calling to a young eagle
perched on the top of a tall pine.
They tried to land beside it but the
combined weight tipped the tree and
all three sailed out over the valley,
filling the air with their cries. Every-
where in the area bird life is very
sparse—we did have a family of Red-
backed Shrikes in the grounds of the
hotel at Varzo—the parents used a
flag pole as a vantage point to swoop
on insects as they flew across the
meadow.
Another trip down the valley of
the Toce lead us onto a road running
parallel with the main roadway but
on the other side of the river. Here
we found the meadows were more
heavily grazed and cut and the
flowers much reduced. The unculti-
vated areas were very rocky and
with the sun unclouded the heat was
oppressive and collecting was tiring.
We found a coppice of False Acacia
(Robinia pseudacacia Linn.) beside a
rocky stream bed which cut across

A CAGE FOR
OVERWINTERING PUPAE
A cage for overwintering pupae or
for keeping larvae can be improvised
from the one Ib. plastic containers in
which Canadian honey is sold in
Supermarkets.
The central portion is removed
from the lid, leaving little more than
the rim. Small holes are cut in the
bottom of the container for drainage
(in the case of outdoor storage) and
it is a good idea to cover the bottom
of the container with a layer of
~~ Drainage holes ———

coarse sand.
A piece of netting (e.g. nylon
chiffon) is held over the top of the
container, and the lid, prepared as
above, is clipped on over the netting.
This puts a slight tension on the
netting, and holds it firmly in place.
A hot piece of thick copper wire is
a useful tool for cutting the lid and
piercing the drainage holes. Alter-—
natively, the lid can easily be cut as -
required with scissors.
The resulting container is hygenic |
and easily cleaned. It will stand any
weather and is proof against birds. ©
It costs practically nothing and will
last a long time. In the case of emerg-
ing microlepidoptera, a piece of glass
can be substituted for the lid and
netting. !

SCALE INSECTS IN
SOUTHERN ENGLAND
A new species of scale insect,
| belonging to the genus Pulvinaria, has
» been discovered on trees in Southern
'England, infesting especially the
‘Horse Chestnut (Aesculus hippcas-
\
i
tanum Linn.) but also the Elm (U/mus),
\vy (Hedera helix Linn.) Holly (Ilex
aquifolium Linn.) and Hawthorn
(Crataegus). Particularly —_ heavy
‘infestations have been noticed on
;noticed at Pesthouse Common, (near
_Richmond Park, Surrey), and along
133
Kew Road adjoining Kew Gardens.
The species is a member of the order
Hemiptera and belongs to the sub-
order Homoptera. A member of the
family Coccidae, it has only been
discovered so far in the female sex,
which indicates the probability of a
parthenogenetic life cycle, that is to
say, the virgin females are capable of
laying fertile eggs which always result
in females. In this system males are
never produced naturally. The
females can be seen resting on the
small branches of trees as small oval
scales. The insects have sucking
mouth parts, characteristic of the
Hemiptera, and they are embedded
into the bark of the tree, whence the
insect sucks out the sap. Conse-
quently, in large enough numbers,
the insect becomes a great threat to
a tree and presumably would eventu-
ally kill it.
The insect’s life cycle can be divided
into three parts. In the first and
second stages the legs of Pulvinaria
differ—the length and shape of the
joints varying. In the third or adult
stage the females produce white
ovisacs underneath the scale, and it
is thought, although not confirmed,
that the ovisacs’ eggs are dispersed
by the wind. The white ovisacs are
fluffy in appearance and immediately
they are produced, the presence of
the insect is obvious, even to the
casual eye. It is not yet known
precisely when each stage starts and
finishes, but as a rough guide second
stage insects are found in March and
April and sometimes adults are
abroad in late March.
At present Holly is thought to be a
secondary host, and perhaps Elm as
well. (Aduit insects were found on
Holly at the end of March at Pest-
house Common). Other localities
where there are confirmed out-
breaks are Syon Park in Isleworth,
Middlesex (on the doorstep of the
Gardening Centre), at Osterley Park
and along the Great West Road near
134
London Airport. As these localities
were taken at random and visited
especially, and outbreaks were found
in each case it tends to show that the
infestation is much more widespread
than was at first thought. Several
theories have been put forward to
explain the origin and spread of the
infections but all are just suggestions
and have no proof. It seems that this
topic would provide much room for
research into the way the insect
established itself in the first place,
and how it spreads. Is it brought here
by aircraft via London Airport, or by
road? Is it possible that the infesta-
tion is spread by wind or perhaps by
the traffic which streams past the
trees? Many of such questions can
only be answered by actual field study
of the insect in its natural surround-
ings, and much help is needed from
all levels to map this insect, and, if
necessary, exterminate it if it
becomes a serious threat to our
already fast disappearing trees.

LETTERS TO THE EDITOR
Sir,
With reference to Mr Plester’s
note (Bull. amat. Ent. Soc., 27: 33-4)
on the sensitivity of ‘gnats’ to sound.
| wrote a note on this subject in
the Entomologists Monthly Magazine
(Ent. mon. Mag. 1941, 77: 96) obser-
ving how some swarms of small flies
by a lakeside near St Paul, Minnesota,
USA, jumped at certain sounds during
the conversation of three or four
observers—particularly a — short
cough. They also responded strongly
to the shaking of a bunch of keys. But
none of these sounds was continuous
so the question of attraction did not
occur.
My note was in reply to an earlier
note in the same volume page 63, by

Sir, |
| have read with interest Mr B. A.)
Mason’s contribution under the)
heading “‘Some Notes From Essex’’
in the Bulletin for May, 1968, but |
am afraid that in the observation of
the White Admiral Butterfly (Limeni-
tis camilla Linn.) in Essex ‘‘fifteen
miles from Aldgate Pump”’ he has not
made entomological history! | believe
that the species has long been estab-
lished in the woodland to which he
alludes and | encountered it almost
annually in its proper season in the
‘twenties and ’thirties, when | visited
the area fairly frequently. Always,
however, it was scarce and the
observation of more than one or two
individuals in a season was unusual.
Incidentally, specimens from this
Essex wood are approximately the
same size as those from the New
Forest which, in turn, appear to be
fractionally smaller than those from
West Sussex.
In Mr Mason’s Essex woodland
Argynnis cydippe Linn. appeared to
have a parallel status and was equally
scarce.
It is nice to know that the White
Admiral is still there and | wonder
whether Mr Mason has encountered
the Fritillary ?

The four who did care were
(4198J), Barbara
and Lance Chilton (4198J). Twelve
year old Elizabeth of 3 The Drive,
“Wellingborough, Northants., asked
‘for set specimens of the Buff Tip and
Red Underwing Moths for her prize.
| gather from a report she sent in that
“she takes
her entomology very
seriously. Elizabeth lives near Apsley
'Heath which, although it is mainly
conifers, has provided her, on various
expeditions, with some interesting
specimens. On June 2nd she took the
' Many Plume Moth (Orneodes hexadac-
‘tyla Linn.) and the Skipjack Beetle
_ (Athous
haemorrhoidalis Fab.). On
June 9th the Long Horn Beetle
_(Rhagium bifasciatum Fab.) a northern
species, turned up along with that
Harpalus aeneus
fellow with the coat of many colours
Fab. the Bronze
'Harpalus (Ground Beetle). A beetle

actually caught with a net while on
‘the wing, this was the fierce little
tiger Cicindella campestris Linn.
On July 7th a formidable but quite
harmless Greater Horntail Wasp

pupa she found on April 28th emer-
ged on May 12th as an Angle Shades
Moth (Phlogophora meticulosa Linn.);
while from mid-April her Indian
Stick Insects (Carausius morosus
Brunn.) began hatching and hatching
and hatching.
There is a little Minor Moth
(Procus sp.) fluttering outside my
window just asking to have his name
put down in my little book for
Nature Conservancy records.
Barbara Brant lives at 40 Castlebar
Park, Ealing, London, W.5., and
being keen on the larger moths
especially ‘Hawks’ requested some
livestock of the Japanese Privet Hawk
Dolbina tancrei for her prize.
| know that Barbara has been
working on moths for the last two
years at least, being both interested
in rearing, and observing her favour-
ite insects. During this year she has
been breeding Lime Hawks, Poplar
Hawks, Early Thorns, Vapourers,
Gipsy and Muslin Moths and by early
July they had all pupated with the
exception of the Early Thorn. Her
Privet Hawk laid a number of eggs
and it is hoped that they all hatched
out. Barbara says that on just one
day, 6th July she saw the Comma,
Small and Silver Spotted Skipper,
Meadow Brown and various Whites
all of course being Butterflies as well
as a Latticed Heath Moth (Chiasmia
clathrata Linn.) and the larvae of the
Knot Grass Moth (Apatele rumicis
Linn.). | do hope she keeps on enjoy-
ing her scientific hobby as she
obviously does from her letters.
Donald Firth is 16 years old and
lives at 22, Manor Way, Purley,
Surrey, CR2.3BH. His prize was some
Corsican Stick Insects (Clonopsis
gallica Charp.) which arrived ‘slap-
bang’ in the middle of his G.C.E. ‘O’
level examinations. He did find time
(Sirex gigas Linn.) was caught along
-with a Golden Swift Moth (Hepialus
-hecta Linn.) and a White Border
*Moth (Bupalus pinaria Linn.).

light trap for the total cost of £4 10s.
including wiring, a mercury vapour
bulb and choke. The trap appeared
136
to work quite well as on the second
night of running it caught an Eyed
Hawk Moth, and from then he says
it went from strength to strength. In
one month he has taken eight
Elephant Hawks, a Small Elephant
Hawk (Ist record for his area) six
Poplar Hawks, six Privet Hawks, an
Eyed Hawk and a Lime Hawk. In one
week in the middle of July Donald
was catching as many as 500 moths in
each night, and even caught three
Sparrows (birds) which made it
necessary for him to make the trap
hole smaller.
Donald is also very keen on rearing
Moths and has managed to get all
seven of the Elephant Hawk Moth
caterpillars he found to pupate. He
hopes to release the imagires (adults)
next year. On the 19th July he had an
Indian Moon Moth (Actias selene
Huebn.) emerge with very strangely
curved tails to its wings. He thinks
that the specimen is quite large for
this species being a male with a 62”
wing span. A pairing between two
different species of Silk Moths, a
female Antheraea pernyi G.-M., and a
male Antheraea harti Moore, resulted
in 150 eggs which if they hatched out
will have produced some interesting
mules (not horses). Finally Donald
was hoping to spend most of his
summer holidays doing some form of
natural history or other. He was to
have spent the first week of August
camping with the National Trust on
Golden Cap, Lyme Regis where he
expected to obtain many Garden
Tiger Moth larvae, the rest of the
Summer he was to have spent in
Asiatic Turkey. | do hope he was not
joking as | am sure we should all be
looking forward to hearing about
such a exciting expedition. Donald
has a friend in France who is interes-
ted in natural history; do any of you
correspond with naturalists in other
countries?
Exciting expeditions do not remind
me of school but while | am thinking

about school | am reminded, by my |
son who is doing a project on Beetles
in stored food products for his
examinations, that | ought to offer)

kind of ordeals. Please do not hesitate
to write if you think that | may be
able to supply you with live insect
etc. for projects. If | do not actually
have the animals you want | might
know someone who has.
‘Some one’”’ else reminds me that
| must not dare to close the news
section without mentioning the last
of the May Quiz winners. He is Lance
Chilton of 2 Castlefields Drive,
Charlton Kings, Cheltenham, Glos.,
Lance asked for some Indian Stick
insects for his prize and now has
some Madagascan Sticks (Sipyloidea
sipylus Brunn.) and some Corsican
Sticks. He tells me that his Indian
Sticks took a fancy to Willow Herb
and Strawberries. | have heard that
these insects can cause havoc in a
greenhouse if they escape among the
valuable plants housed therein. | have
just checked my two pet tomato
plants and found a big hole chewed
out of one of the leaves. | wonder
whether a stock of Indian Sticks can
survive on plants other than Privet or |
Ivy. I'll just put back this ruffianlay

55/- Second Edition 1968.
There has been a recent trend
‘amongst our members to take an
interest in the, perhaps, less popular
-orders of insects, such as the Hymen-
‘optera, Odonata and the Diptera.
‘Those members who have chosen
the true flies or Diptera have been
extremely lucky in having the first
edition of this book as an excellent
guide. This new edition has been
‘revised and published in an enlarged
format but still retains all those
features which make it such a
remarkable book.
The introductory chapter explains
what the flies are, how to distinguish
them, their general structure, while
also defining the terms used by
dipterists in description and identifi-
cation. Full page figures show the
features of each main group of flies
and compares their structures. A
general account of their life history
is given with illustrations of the main
larval types. An introduction to
classification is also given here.
The bulk of the book deals, in turn,
with every family of flies found in the
British Isles, each chapter describing
a natural group of families. For each
family there is given a_ technical
description followed by a description
of representative genera and species,
including life history and habitat. It is
in these sections that the author’s
personal anecdotes render the book
so readable. Notes are also given on
medical and agricultural interest.
The book is illustrated through-out
by original, enlarged microscope
drawings by C. O. Hammond, many
of which are in full colour. By means
of these, a great many of our most
common and interesting flies can be
identified at a glance, the identifi-
cation being checked by consulting
the text.
At the end of each section of the
book detailed keys to families are
provided with other smaller keys in
the text. At the end of each chapter
are extensive bibliographies enabling
the reader to follow up his interest
in more specialist publications.
The appendix includes a large
section giving detailed accounts of
the methods of collection, preser-
vation and examination of flies giving
many practical hints. Notes are
included on the use of the micro-
scope, and also of methods of packing
specimens for posting.
A valuable feature of this section
of the book is the glossary, defining
approximately 400 technical terms
which puzzle many beginners when
138
using the keys and more advanced
books.
This book is suitable not only for
the specialist but more specifically
for all those interested in our British
insects.

This work is the latest in the series
issued by Blandford Press and follows
‘Woodland Life’ and ‘Pond and
Stream Life’. It is meant for the
beginner or perhaps better still for
the person with a general interest in
natural history rather than the
specialist in one particular branch.
This work appears originally to have
been issued in Denmark for the use of
the continental naturalist and it has
been excellently translated into
English. | find however one or two
disappointments in this work. Bearing
in mind that it is for the general
naturalist, why include the Praying
Mantis and the Migratory Locust not
likely to be met with in the English
countryside, or again why include the
microlepidoptera like Nepticula or
Crambus silvellus which is incidently
given in the text as C. myellus?
Another thing there is no indication
of the relative sizes of the creatures
in the illustrations, this can be a little
confusing to the beginner. | found the
illustrations of the Beetles, Plant Bugs,
Flies, Galls etc. very good, | cannot

THE AES ADVISORY PANEL
:
: How and when to consult the
Panel
Members of the Panel will advise
you on the study of their special
groups and will identify small num-
bers of British specimens which are
of particular interest to you. Large
collections should be taken to a
‘museum for identification. Try to
use a copy of the relevant standard
-work if you know of one, before
approaching the Panel.
Always mention that you are
-approaching the Adviser as he is a
‘member of the Panel and give your
own Membership number. You
‘must enclose postage stamps to
‘cover the cost of a reply or return
-of specimens. Members of the
‘Panel are busy people, so try to
‘send dead material to them during
‘the winter when their own time is
less likely to be taken up with field
swork. You are recommended to
‘send a stamped addressed en-
svelope for acknowledgement of the
‘receipt of material which may have
to await time for its indentification.
| Labelling — with details of locality,
‘foodplant, date, time and mode of
‘capture, etc. — often greatly simpli-
‘fies identification. Every specimen
»should be fully labelled on the same
/pin as bears the specimen or its
‘mount. Details of locality will be
treated as confidential if this is
desired.
| The Society is most grateful to
che many specialists who serve on
this Panel, without any remunera-
‘tion other than the occasional speci-
‘men taken, with permission, from
san interesting series that has been
sent in. It is hoped that Advisers
-on those groups that are noticed
incidentally or as pests will be
_suught after as frequently as members
-of the Panel willing to identify
“commonly collected Orders.
New advisers on appropriate sub-
jects not covered below are always
welcomed by the Hon. General
Secretary.
