Telephone: Yeovil (0935) 4608 RES a No. 314 BULLETIN EDITORIAL While I appreciate the thought that causes members to write me long chatty letters I must relunctantly but firmly state that, quite apart from Editorial duties, I do have masses of other work to attend to and just cannot spare the time to reciprocate in kind. I hope this will assure all past and would be correspondents that their epistles are noted and that they will accept this brief editorial as a joint reply. I do try and acknow- ledge all matter received, but for various reasons even this sometimes takes a week or two. I would also like to thank all those who send me correctly typed and spaced manuscripts and to point out to others that badly presented material will always be subject to extra delay. All authors please note that tables should always be on a separate sheet of paper and not incorporated in the text. Coloured illustrations are also unacceptable. They can be redone, but this again leads to further delay and probably a sad loss of quality compared to the original. CHILD AND BEE CHILD: Go away, go away, naughty Bee, Leave me, I tell you, instantly, You want to give me a sting, I know. BEE: Let me speak, and don’t scold me so, a You’re always with me so angry and cross, If I gave no honey, you'd feel the loss Now, when the child thought the matter o’er, He scolded the busy bee no more; But saw how it hover’d the flowers about, Sucking from each the sweetness out, And all his fear of the sting lost he, In praising the insect’s industry. F. Hey ANNUAL EXHIBITION 1976 Our Ehibition was held on Saturday, 2nd October, 1976 at University College School. After a run of successful and increasingly popular Exhibitions at Holland Park School, we were faced with the problem of finding a new venue, as our former premises were no longer available. A large number of possibilities were investigated and we were very fortunate in obtaining FEBRUARY, 1977 ee sd yh AES BULLETIN, Vol. 36 3 permission to use the Halis of the University College School at Hamp- stead. These offered an impressive setting, fine facilities and good availability. Our congratulations must go to our Organiser, Mr. Bernard Skinner who, faced with an entirely new set-up, produced a first rate Show with an absence of complications. In general, Dealers occupied the ground floor of the Main Hall, Exhibitors and Demonstrations used the balcony and adjoining rooms and the Refectory was reserved for refreshments and the popular St. Ivo School exhibition. A number of useful suggestions for improvements have been received and these will be considered along with our own ideas, for future occasions. In his opening speech, our President, Mr. B. A. Cooper, a founder member of the A.E.S. and author of most of our earlier publications, spoke of the trials and tribulations of those years. But the most signifi- cant factor for him was that some 50 years ago, as a very junior pupil of University College School, he first became interested in insects. From this inspiration, the A.E.S. emerged and now, half a century later, he was privileged to chair the first A-E.S. Meeting at his old School. The primary object of our Exhibition is to provide an opportunity for entomologists to show their current work and discuss matters of interest. While it was most encouraging to have a capacity attendance throughout the day, it was disappointing that a Society of some 1,300 members could not produce more personal efforts. Many observers commented that the exhibits were outstandingly good but there was an absence of more average displays. Members may not have the time to prepare anything elaborate but if they would bring a small contribu- tion, this would encourage many others to do likewise. Surprisingly few persons noticed that Independent Television cameras were present. Our member, Gordon Trebilcock, is arranging a series of natural history programmes which are expected to be shown next year and our Council agreed that our Exhibition might be used as the ‘back-cloth’ for the final Show. Part of the material for this series, a video film of British butterflies photographed in the field during the marvellous 1976 summer, was shown continuously throughout the after- noon. Our major attraction of the day was the presence of Dr. Sutton and Mr. Peter Hudson, two entomologists who took part in the Zaire River Expedition in 1975. Dr. Sutton described their objectives and experi- ences and illustrated his talk with slides, equipment and local material. Typical insects were on show, forming part of an estimated 30,000 specimens brought home for study. Two of our regular features which are always popular are the prizes for the best Junior exhibits and the practical demonstrations and talks. Three excellent Junior projects were chosen, N. J. Armes—Ist prize for his survey of Dung Beetles, N. James—Moths of Worcestershire 4 FEBRUARY, 1977 and M. Smith—Life history of Bumble Bees. Details of these are in- cluded in the subsequent list of exhibits. Probably one of the most difficult operations for lepidopterists is overwintering larvae and three experts in this field, Maitland Emmet, Peter Cribb and Eric Bradford presided over a most interesting discussion on their techniques. The AES Council wish to thank all the members and friends of the Society whose work ensured the success of our Exhibition, fully appreci- ating that a new venue posed many problems. They are especially grateful to Joan Hilliard and the team of willing and efficient ladies for providing attractive refreshments all day; Eric Bradford for producing Fig. B. Our President, Mr. B. A. Cooper (left) talking about bees. AES BULLETIN, Vol. 36 5 a comprehensive supply of signs and posters; the members who donated surplus material to the Society and Peter Taylor who master-minded the sale; Stephen Cribb filling the difficult Enquiries desk post and David Keen and others who presided over the sale of publications. Not least, an appreciation of the stalwarts who on the previous evening and before and after the Show, shifted furniture. erected and dismantled tables and tidied up. Reports were received for the following exhibits:— AES CONSERVATION GROUP. The general theme was site and habitat protection, a main objective of the Group. D. Lonsdale, P. W. Cribb, N. Cooke and E. Bradford showed detailed case studies of two important areas, Ditchiing Common and Tenantry Down. AES EXOTIC INSECTS GROUP. A wide selection of living foreign lepidoptera. An attractive feature, when breeding exotics, is their availability at times of the year when most British species are dormant. ALLEN, A. A. (5788). Parasitic insects of two groups, Braconidae, sub- family Rogadinae and Ichneumonidae, sub-family Campopleginae, with detailed life histories and host preference. A selection of microlepidop- tera with notes on behaviour and localities for each species. ARMES, N. J. British Dung beetles, Geotrupidae, in particular, G. stercorarius L. whose coprophagous habits are critical as a remover of dung from fields. There is very little literature on this species and this exhibit included large original line drawings illustrating the life history, habits and morphology. An identification chart for the 8 British species of Geotrupidae. AWARDED FIRST PRIZE. ASHDOWN, P. D. (2823). Insects and other arthropods from the Cen- tral American country of Belize.

Hilliard (99) BEETLES ARE TOPS WITH SCHOOLBOY Dung beetles might not be the most attractive members of the insect community, but a 16-year-old St. Ives schoolboy is glad they captured his interest. For Nigel Armes, of the St. Ivo School, has won a top national award for his work studying them. Nigel won the junior section of a competition run by the Entomological Society. Nigel is a member of the school insect and wildlife club, and along with 45 boys and girls took his work to the society’s annual exhibition in London. “Nigel’s work, a study on dung beetles, was really excellent, and he won first prize in the junior section”, said the school’s biology teacher, Mr. Henry Berman. The exhibition had a further surprise, because one of Nigel’s former schoolmates, Mathew Smith, aged 15 took the third prize. “Mathew left St. Ives to live in Reading about two years ago. It came as a big surprise when they read his name out as one of the prize winners and we realised he used to go to the St. Ivo,” said Mr. Berman. [The above extract appeared in “The Cambridge Evening News” the week following our exhibition. Mr. Berman really is to be congratulated on the way he drums up and sustains the enthusiasm of his pupils for their subject and for all the work he puts in, not only in bringing his St. Ivo group so regularly to our exhibition, but also to all the other functions I know they attend and put on such a good show.—Editor] nning exhibit. n Gardiner.

Overton) (Photos B to | : AES BULLETIN, Vol. 36 13 THE HIDDEN WONDERLAND OF CRETE My first impression of Crete was that it was a sub-tropical place, hitherto unknown to all but the inhabitants. But one of the first places we drove through on our way to our villa was Agios Nikolias—the set- ting for the BBC TV series, “The Lotus Eaters’. Our destination was Elounda and two hours after arriving I discovered my first Scarab—a male Catharsius molossus L. Flying round nearby lamps were the Cantharid Rhagonycha fulva Scop. as well as the moths Erannis defolaria and Lymantria monacha. Next day I wandered along the shallows by the beach, watching Egrets feeding and wading, and discovered Staphylinus caesareus and the Carabid Carabus glabratus and the Tenebrionids Crypticus quisquilius L., Melanimon tibiale Fab. as well as a strange bug I cannot identify. The Ant Camponotus gigas was everywhere, carrying all sorts of things in its jaws, but mainly wheat and grass seeds. I rounded off my first day with a swordfish steak and aubergine salad in the village restaurant. The following day I spent sightseeing and window shopping but for a couple of hours in the early evening I managed to photograph some insects. But it was not easy as there was quite a wind blowing, sending dust in all directions and there were plenty of mosquitoes about as well. Next morning I struck out in the opposite direction, walking to the other side of the bay at the far end of the village. During my walk I noticed that some flowers—I believe it was wild parsley—had attracted a host of insects. Among them I found the Buprestid Anthaxia candens the Chrysomelid Chrysomela anea, the Cockchafer Epicometus hirta, Trichodes alvearius Trichodes apiarius, Anthrenus scrophulariae and Mordella pumilla. Further along the road I found the Carabid Scarites euparius and on more wild parsley I dis- covered the bug Graphosoma lineatum, Cercopis vulnenata Illinger, the red bug Lygaeus kalmi and what I believe was a Megalonotus bug. Flying around everywhere was the huge bee, Xylocopa violaceus which not only frightened the insects. I later on saw one land on a woman’s hair which almost frightened her out of her wits. I noticed also the strange insect Palpares solidus, not to mention a large creature, like a dragon fly which was greatly attracted by lights at night. Later on I visited the museums in Iraklion which contained the treasures excavated from the Palace of Knossus. Later, at the palace site I discovered, crawling over the dusty ground. the weevil Cleonus piper and on a tree by the souvenir shops I found the Alleculid Ctenopus flavius. After Knossus we went to the less well known Minoan palace of Mahlia where I found the dung beetles Onthophagus vacca and Aphodius luridus. Our guide, when asked, said the soil on Crete was ‘argillic’ soil. 14 FEBRUARY, 1977 It is brick red and the guide said the land was very fertile, so fertile in fact that anything could grow there, including oranges, palms and Olives. That day’s sightseeing over. I returned to one of my favourite haunts in the hinterland of the wild parsley. There I caught and as yet, a still unidentified Bupestrid, orange and green in colour. That evening I dined on fried squid, with chips of course, washed down with beer. The temperature during the holiday averaged between 70 and 80° F. and on one day it even reached 100°. The locals call the Cockchafer ““muscari” and the big Hoplia philan- thus flies around the buildings and among the olive trees. But down by the beach again I found the beetle Necydalis major L. among the ever present parsley. In fact, wherever I went, whether along the beach, in the fields or even along the streets of the villages, I found insects, bugs and beetles. Certainly, as I sat in the bar on my last night I realised that discover- ing the hidden wonderland of Crete had been very fulfilling. Taking colour photos of the insect life had been challenging and in fact the whole holiday had been an adventure. I feel sure that anyone else who goes to Crete will enjoy it as much as I did. M. JOHNSON (3464 J) NOTES ON SOME OF THE PARASITES ARISING FROM MATERIAL COLLECTED IN SOUTH FRANCE—MAY 1976 I sent this material to Dr. Mark Shaw at Manchester who has kindly made the following coments : — 1. Host—the pupa of Euphydryas aurinia provincialis Bois. The pupa was found near Digne and failed to hatch but on our return to England it produced a mass of small wasps. They are of the genus Preromalus, similar to P. puparum L., but differing in some characteristics in the males. Possibly an undescribed species— Dr. Shaw has had previous examples from other Nymphalidae from S. France. 2. Host—the larvae of E. aurinia provincialis. Larval skin and cocoons found near Fayence. The emerging wasps proved to be Apanteles melitaearum Wilkinson, a parasite of E. aurinia in Britain. Emerged in post to Dr. Shaw. 3. Host—young larvae of Nymphalis polychloros L. At St. Paul-en- Foret. Single parasite to each larva which spins a small cocoon after emerging from the larval skin. Apanteles ?plutellae Kurdjumor, a solitary parasite known to attack Aglais urticae L. and Plutella xylo- stella L. an unusual combination. 4. Host—young larvae of A poria crataegi L. A mass of cocoons appear- ing outside the dead larval skin, similar in appearance to those occurring with the Large White. Pieris brassicae L., but the cocoons not the bright AES BULLETIN, Vol. 36 15 yellow of Apanteles glomeratus L. These proved to be Apanteles pieridis Bouché, only known from 4A. crataegi. All the above are Hymenoptera. A. crataegi also produced dipterous pupae but these were unfortunately lost. 5. Host—half grown larvae of Anthocaris belia euphenoides Staud. gathered near St. Paul-en-Foret. A single small cocoon formed on the stem of the foodplant beside the shriveled larva. The parasite is a Braconid, Microplitis sp., but the species is undertermined. Dr. Shaw had previously recorded this wasp from both Euchloe ausonia Hbn. and E. tagis Hbn. feeding on Biscutella sp., the same foodplant as eupheno- ides, so that the parasite may be plant rather than host specific. 6. Host—ovum of scarce Swallowtail collected on Sloe at St. Paul. The egg failed to hatch but from a hole in the shell emerged six minute wasps, distinguishable only by means of a lens. These were Trichogram- mitids (Chalcidoidea) of an undetermined genus. (The above material is in the collection of Dr. Shaw). P. W. Cribb (2270) CONCERNING BRITISH BUTTERFLIES In an extensive review of South’s British Butterflies by T. G. Howarth, Dr. J. R. G. Turner, (Turner 1973) provocatively raised, in an American Journal, a number of interesting factors which are, I feel, of general interest to all British Entomologists, but perhaps only of passing interest to American ones. Many of the points and queries raised in his review deserve an answer, or, in some instances, further research and comment. One of the first queries raised concerns the earliest recognisable picture of a butterfly species and asks for any advance on 1503 where the Meadow brown (Maniola jurtina L.) and Small tortoiseshell (A glais urticae L.) can be recognised in a painting “The garden of delights” by Hieronomus Bosch. We can certainly go back a long way past this. I can recognise a Colias in “The Romance of Alexander” of 1338 (Ms. Bodley 264). I also have a copy of another Ms., of about the same date but whose provenance is unfortunately lost, clearly depicting a very familiar enemy, the Small white, Pieris rapae L. Both these Mss. show a number of other (and highly improbable) species and the former clearly shows nets (possibly converted from certain hats of the period) being used by children chasing the butterflies. I feel sure that a study of illuminated mediaeval Mss. would reveal many recognisable pictures of butterflies and moths. Has any Entomologist ever done a study of Roman mozaics, Pompeiian wall paintings and Egyptian tomb painting? After all the Scarab beetle is well represented in Dynastic Egypt. Butterflies did not play a part in Egyptian religion as did the Scarabs, but it would be worth a look. Incidentally, the earliest fairly easily recognisable description (as opposed to picture) appears to be of a 16 FEBRUARY, 1977 Clothes moth or rather its larva (Tinea sp.) and is found in various places in the Bible (e.g. Isaiah 51.8). Dr Turner believes that the literature is extensively misleading on some species and asks if it is true that the Ringlet (A phantopus hyperan- tus L.) is a shade butterfly. I think that the question as to whether a particular species is a shade buterfly (or a woodland, or open field butterfly etc.) would be better phrased by asking the corollory “Is it foodplant a shade plant, etc?” Does the larva of the Ringlet in fact prefer the coarser stronger growth formed by grasses growing partially shaded? In my experience the Ringlet is a shade loving butterfly. I also think that it deserves to be pointed out that when making studies of the sex ratio of feral populations one has to make certain that one is not producing a ratio of foodplant abundance as appears to have happened in some records I have seen, of, for instance, Pieris. It is on the subject of Pieris, however, that I really wish to take Dr Turner to task. I would like to know the books he has consulted and which state that the Green-veined White (Pieris napi L.) does not occur in cultivated land. I have consulted twenty books from my library and not a single one of them makes such a statement. Mostly they are am- bivalent (making vague statements such as “generally common”: “Wide- ly distributed”, or they are specific in making the following statements which are in direct contradiction to that of the books consulted by Dr. Turner: “...also fields of different kinds of Cruciferae...” (Frohawk, 1934); “In our gardens we may find both eggs and larvae...” (Furneaux, 1905); “...may frequently be found in gardens and cultivated ground also” (Stokoe, 1944) “Frequents gardens...” (Lang, 1884); “Both in woods and cultivated grounds...” (Coleman, 1880). However, I am perfectly prepared to qualify these statements to a certain extent. I believe the Greenveined White does occur, often commonly, on cultivated land, as an adult but not as a larva, and it does not often penetrate far from the boundaries of large fields, unlike the Small white which does. It is also exceedingly rare to actually find its larvae on cabbage as such, P. napi prefers Rape, Mustard, Watercress and various wild weed Cruciferae, whereas P. rapae has a marked preference for cultivated hearted cabbage plants. It also prefers moister and shadier situations than rapae although it is of course always possible that these two conditions go together in many cases. The surprising statement is made about “The impossibility of separat- ing British Pieris on the wing....” I totally disagree about this alleged impossibility of separating British Pieris on the wing. When I was a boy I could do it with a better than eighty per cent probability at 50 yards and, out of practice and no longer so keen sighted, reckoned I could still, and put this to the test recently in a walk along the Cromford canal in Derbyshire. My score was 4 out of 4 for Pieris brassicae L. 28 out of 29 for P. napi and 5 out of 5 for P. rapae. Rather a better AES BULLETIN, Vol. 36 17 ———— result in fact, than when I was younger! Only those specimens whose identity could be positively confirmed by capture or subsequent settling close by on a flower head were counted. Scores were made only on flying insects and the distance varied from about three to thirty yards. It is I feel a matter of experience; watch and then catch, every white in sight, after making a guess as to what it is first. After a time one Tecognises certain nuances in the behaviour of the different species and also where they are flying. As mentioned above, for instance, a white in the middle of a large field is far more liable to be P. rapae, perhaps nine out of ten, whereas at the edges it can be a straight fifty/fifty and in a moist shady lane one to twenty in favour of P. napi. The Large white is too big to be confused with either the other two. Another rather surprising series of statements by Dr Turner require quoting in full; he states “my only qualm about this lovely new book is for the plight of the beginner and the schoolboy, who need a little more help with identifications which are childplay to Graham Howarth: how does one distinguish the various female Blues and Hairstreaks at a glance, and for the beginner or general naturalist, what distinguishes the Grizzled and Dingy Skippers? Confusion of these last resulted in several incorrect records, now expunged, in the Provisional Atlas’. I do not share Dr Turner’s qualm about the plight of the beginner and schoolboy needing a little more help with identification. From its size it is quite clear that Howarth’s “South” is not a field pocket book and its price puts it well beyond the range of all but the well-heeled. Only after having passed the beginner stage and becoming dedicated to the hobby will the average young amateur entomologist save up for the book. Most beginners and schoolboys in England start with one of the numerous and cheap junior insect pocket books on the market or a 2nd hand old South, Furneaux, Coleman or Frohawk, and I quite agree with Dr. Turner that this is the best way to start. I have consulted my son Christopher; he has now passed the beginner stage, and just, that of schoolboy. He agrees with me that there is little difficulty in distinguishing British Hairstreaks and most of the Blues (Aricia spp. and L. bellargus and corydon females are the difficult ones). I also believe that the confusion between Grizzled and Dingy Skippers must be a lapsus calumni of pen or typesetter! They are totally dissimilar, but Essex and Small Skippers are alike as two peas in a pod. Actually, in my opinion, many identification confusions arise with dead specimens back at home. In the field it is often possible to separate species by habitat and time. In England for instance, one of our Hairstreaks (Strymonidia pruni L.) is so rare that the beginner just does not get the chance to confuse it with the common S. W-album Koch. Not only do they have different foodplants (Blackthorn and Elm respectively), but the one flies high, the other low. Similarly I believe that more studies of behaviour in the field and of the spatial and tem- 18 FEBRUARY, 1977 poral distributions of species could lead to a better understanding of the differences between similar species. The pity of it is that we in Britain, only wish we had far more material to work on, for as Dr. Turner rightly points out, ours is already the most intensively studied butterfly fauna in the world. After allowing for extinct and rare local species there are after all less than fifty species to study and at least ten of these are only sustained in England due to regular migration from the warmer climates of Europe and are not to be seen every year, which doubtless explains why very few English Lepidopterists indeed confine themselves to Butterflies. Most have broken with their insular traditions and now go and study the European continenal fauna as well, but it has always been the habit of the English to study moths, of which we have some two thousand, as well as butterflies, in spite of the fact that only the English language basically differentiates the two! _ Brian O.

FORTHCOMING EVENTS AES ANNUAL GENERAL MEETING:—Saturday March 26th at Caxton Hall, Westminster. See enclosed leaflet for further details. INTERNATIONAL INSECT FAIR:—The second International In- sect Fair of Paris will be held on April 23 and 24 at the Palais des Congres, Porte Maillot, Paris, France, when both professional and ama- teur entomologists from all over Europe will have the opportunity to meet; to exchange; to purchase and to sell the insects of their choice. The price per table for dealers and others is 200 FF. (£25) for two days. So far as we can tell this is likely to be similar to, but much larger than, our own AES exhibition. Further details obtainable from “Association pour la promotion de la science entomologique, 27 Villa Chaptal, 92300 Levallois-Perret, France’, AES BULLETIN, Vol. 36 1s) GUIDED NATURAL HISTORY TOURS:—Cox & Kings Ltd. are running a series of guided holiday tours to places of natural history interest such as Turkey, Czechoslovakia, Afghanistan, Russian Caucasus. Although labelled as botanical, ornithological and photographic, it would seem to us that some of them could prove very interesting entomologic- ally, such as Wengen of which we have personal experience. Further details from Mrs. Joy Randerson, Cox & Kings Ltd., 46 Marshall Street, London W.1. AN ENTOMOLOGICAL WEEK ON RAASAY :—Geoffrey Gill, De- partment of Adult Education & Extra-Mural Studies, 23A High Street, Inverness is proposing to run a course of “The Entomology of an Island” from August 27th to September 3rd with between 14 to 20 Entomolo- gists, amateur or professional, in order that as complete a survey as possible may be made of the Island of Raasay. The evenings would be taken up with lectures and discussions. Accommodation would be in Churchton House (full board), but some country cottages may be rented for those preferring to cater for themselves. Cost details are not yet available and those interested should get in touch with Mr. Gill, address above, as soon as possible. FIELD AND OTHER COURSES FOR ENTOMOLOGISTS:—The Field Studies Council organise many one week courses during the year. The following may be of interest to members: 15-22 July, 1977 ‘Field Studies in Insect Behaviour’ (Juniper Hall, Surrey); 20-27 July “Butterflies and Moths’ (Slapton Ley, Devon); 20-27 July ‘Natural History Photo- graphy’ (Orielton, Dyfed); 6-13 August “Bugs, Beetles and Butterflies’ (Drapers, Gwynedd); 31 August-September Ist ‘Flies, Midges and Gnats’ (Malham Tarn, Yorks.). Fees for these courses, including board, are in the region £30-£45. Further particulars are obtainable from the Hon. Secretary. NEW FRENCH SOCIETY & JOURNAL:—The former “Reunion des Lepidopteristes Parisiens” has moulted into the “Societe des Lepidop- teristes Francais” which intends to publish a regular bulletin to be illustrated with numerous drawings and photographs and in order that it shall be a tie between all entomologists every paper will have an English summary. Obviously of use to all those who collect in Europe and further particulars may be had of Mons. Jean Richebourg-Peyrache, Olympiades 75, Rue du Javelot, 75045 Paris Cedex 13, Erance. MARRIAGE BUREAUX FOR SPHINGIDAE & SATURNIIDAE: —Andrew Sykes is proposing to start a scheme known as ~TELEOP- TERA” whereby breeders of moths who have an emergent specimen but no mate for him/her may ring up and be put in touch with someone who has. All being well the scheme will commence next month. Phoning hours are very strictly limited to between 7.00 to 8.00 a.m., Monday to Friday only, and the number is 01-446-1775. 20 FEBRUARY, 1977 AN INTRODUCTION TO THE SALTATORIA OF CENTRAL AND SOUTHERN FRANCE The insects of this particular order, the Saltatoria, include the Grass- hoppers, Bush crickets and Katydids. It is an order that is frequently neglected by the entomological fraternity. They are easily studied by their relatively large size, and also by their conspicuous markings. In ecological terms they occupy a dominant part of the terrestrial fauna being the prey of large reptiles, birds and small mammals especially insectivores. To the unaccustomed traveller abroad, these insects were by far the most interesting and the most numerous. This account is not, however intended to be a long winded account of all the species but a general introduction based on the experience I have gleaned during my three expeditions to Central and Southern France. COLLECTING, AND FIELD PRESERVATION Where can I find them, and when? The most favourable months for collecting Saltatoria are July and August. If you go there in May or June they are likely to be in early instars, and if you go later in October or November they will be dying off before the winter comes. Saltatoria can be collected in meadows, fields and on hillsides by using the normal type entomological net and pill boxes. Most Bush crickets can be beaten from hedgerows and low bushes that are in the shade but must be “boxed” quickly as they are excellent fliers as well as having the ability to jump to safety. If you intend to rear them you will require a netting cylinder and a deep tray of sand over which it fits. The insects are introduced to the cage in the shade and the female will start depositing ova immediately. Female bush crickets have a large sword like ovipositor which they use to deposit their ova under the hard soil. Grasshoppers on the other hand insert the whole abdomen into the soil and lay a pod of ova. The ova are best laid in sand 3-4 inches deep and the whole container can be brought back providing you frequently moisten the sand. If you go to the trouble of going out at night with a torch and a few pillboxes you will most likely get yourself some of the more elusive Bush crickets, the name is misleading as they are correctly referred to as ‘“‘Long-horned Grasshoppers’ even though they are more closely related to the crickets. If you intend to bring specimens back home you must decide whether you intend to set them while on holiday or at home. I personally prefer to paper mine for two good reasons. Firstly specimens are much less likely to get damaged if in an envelope, in a tin, than if a box of pinned insects is brought back, I also prefer to set them during the bleak winter months when they cannot be collected. The second reason is that if you are setting insects in the field you have less time to sample the local “‘cuisine’”!

Or alternatively they may be dropped into nearly boiling water for 30 seconds then removed. One word of warning, I think, is necessary, NEVER leave them in the open to dry, the reason being that the ubiquitous ants will cut them up piecemeal as a supplement to their diet. For this reason as well it is perhaps best if all papered insects are placed in airtight (Ant-tight) plastic, or metal boxes. You may perhaps ask where are the most suitable localities for collecting orthoptera. If you want the large or the unusual you must go South of Lyons. Areas which will repay further detailed examination are: Provence, Dauphine, Dr6me and general areas including the Central massif and the Maritime Alps. CLASSIFICATION This is not difficult for any beginner just embarking upon the study of this group, but classification beyond genus is more complicated since there is a general lack of texts on this order, especially in the areas out- lined previously. The references at the end of this article give some general guides suitable for preliminary examination. I will attempt to briefly outline the main families. Family name Common Name Diagnostic characteristics Gryllidae True Crickets Tarsi 3 segmented, Dorso-ventrally flattened Tettigonidae Long Horned Tarsi four segmented. The Grasshoppers / antennae are much longer than or Bush crickets the body Gryllotalpidae Mole Crickets Enlarged fore limbs. Subterranean Acrididae Field Grasshoppers Antennae not longer than body. 3 segmented tarsi Nocturnal inhabits caves Elongated pronotum Elongated hind femora Rhaphidophoridae Cave/Camel crickets Tetrigidae Ground hoppers Tridactylidae Pigmy mole cricket Of the seven major families four are mostly rare insects seldom seen, or almost totally obscure. This leaves us with three remaining families one of which we can dismiss as we are not interested in them—the Gryllidae. This leaves us with the Tettigonidae and the Acrididae. A neat division as the Tettigonidae represent the Long-horned or Bush crickets. They have a four segmented tarsi which separates them from their relatives the Acrididae which have three segmented tarsi. If you go really South you might encompass the breeding range of a true locust Locusta migratoria, L. The common red winged grasshoppers, also members of the Acrididae, can easily be captured on any sunny day. There seems to be a slight seasonal variation in the colouration of the forewings which are matched to the substratum. Where the colour of the substratum is light, e.g. roadsides and hillsides, the forewings are also light, with slightly darker bands. Alternatively, where the substratum is dark the forewings tend to be AES BULLETIN, Vol. 36 23 darker and with more clearly defined bands. A near relative of Oedipoda germanica. is O. coerulscens, L. This is a much more widespread species than the former which tends to be restricted to the more southerly portions of France, and a few warm places in Central France such as Die and Gap. O. coerulscens has a more northerly distribution and the author has taken this species just south of Paris on several occasions, as well as its normal haunts around Grenoble in Central France and in the Loire valley in the west. A closely allied genera to the Oedipodinae is the genera Psophus of which there is a single representative, P. stridulus. This is a mountain insect found throughout France generally at altitudes of greater than a 1000 m. The hindwings are brilliant scarlet and the body integument is almost black, a most distinctive species. When disturbed the grass- hopper takes flight revealing the bright hindwings, an example of ‘Flash colouration’, the objective being to confuse and startle a would-be pursuer. Lastly, a species it would be well to include in this consideration of the more interesting Saltatoria is the Italian Grasshopper Caloptenus italicus L., an unusual insect that is, in the authors opinion, a scarce insect in the French countryside. The hindwings are very much reduced in size and are almost transparent with a feint crimson suffusion. In an article of this brevity it would be impossible to consider a representative of all the most interesting genera and so the author has attempted to cover only those species which are immediately apparent to the traveller. Ephippiger ephippiger, Fiebig. is sometimes very common on waste- land at quite high altitudes; the adults sit around on vegetation and are very active! they have atrophied wings which are hidden under remarkedly distorted elytra. Tettigonia viridissima L. is very common throughout the country, much more than in England where it is seldom found except in the South. The females are easily secured either by beating them from low growing bushes or by looking under the flysheets of tents, a very lucrative method. Also found very commonly in the Southern France is the Dark Bush Cricket Pholidoptera griseoaptera Degeer, which is obtained by employing methods similar to those outlined earlier. It is a handsome insect about 40 mm long and there is a noticeable sexual dimorphism, the male is black with a dark rust coloured stripe running down the pronotum, the female is a more usual tan colour with a straw coloured pronotal stripe. In this species the wings are also absent, totally in the female with the remnants of the wings left on the male. This is by most standards a modest discourse on the Saltatora, it will have achieved its purpose if it sheds but a little more light on a fascinating group.

This has been uncultivated parkland for about 200 years with fine Oak trees and Elms. The park also has a river running through it with overgrown Osier beds on one side and small woods with more Oaks, Poplars, Limes, Chestnuts and Elms, bordering the golf course itself. With hope and luck this will continue for the next 200 years. In fact this is a Lepidopterist’s haven as I have large areas of grassland border- ing the hedges etc. which I refuse to cut short, much to the discontent of the golfers. The golf course itself has been in existence for about 15 years and during this time a large number and variety of trees have been planted between the fairways. Stinging nettles are everywhere with meadowsweet and other moisture loving plants. We pump the water for the greens out of the river, and during the drought of Summer 1976 I have witnessed the following butterflies sitting on the wet greens: Small White Pieris rapae L. Meadow Brown Maniola jurtina L. Small Tortoiseshell A glais urticae L. White Letter Hairstreak Stymonidia w-album Koch. I have not seen S$. w-album in this locality for six years, but on 14th July, 1976 I saw several sitting on one of the greens. I did not witness Large Whites, Ringlets, Gatekeepers, Small Heaths, Common blues, Peacocks, Commas or Red Admirals, feeding on the greens in the same manner. I have introduced the Speckled wood Pararge aegeria L. to this locality (1972) and it thrives, but is never common. The Purple Emperor A patura iris L. has never been seen here to my knowledge, although Sallows abound everywhere with Oaks next door, perhaps they could be introduced by some kind soul as they would be protected 365 days of the year!—T. M. Shipp (5079) CONVOLVULUS HAWKMOTH IN YORKSHIRE: —I should like to record that on October 19th, 1976 I captured a perfect male specimen of Herse convolvuli L. at Acomb, Yorks. The specimen was found AES BULLETIN, Vol. 36 25 ea during the day at rest on a neighbour’s drive. It would be of interest to know whether this was a late migrant or had bred locally, the off- spring of an earlier summer migrant:—A. J. Gillery (3653) CONVOLVULUS HAWKMOTH IN HERTFORDSHIRE: —In Octo- ber of last year a dead specimen of H. convelvuli was brought to me by Miss P. Hutchison, who had found it in her pantry at Barley, Herts. Rigor mortis had set in but otherwise it was a good specimen:—Brian O. C. Gardiner (225) PINK POPLAR HAWKMOTH:—On the 18 of June, 1976 I had a very pink female Poplar hawk (Laothoe pupuli L.) hatch, from a pupa I dug up in the winter from under an Aspen tree. Unfortunately she was crippled, but nevertheless succeeded in mating with a perfect male. She laid me 84 ova, of which 62 made it to the pupa stage (I would have had more if I hadn’t overcrowded them). This year, on the 17th of June I had the first one hatch. A perfect female, and fairly pink. I managed to pair her with a wild male, and so far she has laid me 70 eggs. From that date I have had another 24 hatch, including a very pink female, the colour of a pale boiled lobster; also a couple of males not so pink as the females. I would like to see if I could breed a complete pink or red form and would be more than grateful for any suggestions that members can give. If ever I do, I'll let you know all about it.—Ken Williams (5396) EARWIG FORCEPS :—When one mentions the earwig it is the thought of the forceps or callipers which springs to the minds of most people. These formidable pincers are usually what put people off the earwig, apart from the fact that they are ‘creepy-crawlies’, and supposed to enter one’s ear and bite their way through to the brain. But to the ento- mologist or anyone who studies the order Dermaptera they are a very useful facet in classification and determination of the sexes, as well as being a recognition feature of the order. But what of the use of these modified cerci to the earwig itself? In the common species, Forfi- cula aquricularia (L.), I have observed them being used for injuring caterpillars before moving in to kill with their mandibles, and as organs of offence—any disturbed or alarmed earwig will raise its abdomen in scorpion-fashion; even the young nymphs who have not fully developed callipers, I have also heard of them being used for catching prey, levering themselves out of awkward situations and to help fold away their wings. {wold be very interested to hear any further reports of the use of forceps in the Dermaptera, particularly of our few other species.— J. Good (5398 J) ITS JUST “DESSERT” :—On my return home from a hot and sunny 26 FEBRUARY, 1977 field trip, at 4 p.m., on August 11th, 1976, I was immediately greeted by the most unusual spectacle of a Common wasp, (Vespula vulgaris, L.), demolishing the entire body of a Nutmeg moth (Hadena trifolii, Hufn.) laid out at the bottom of an upright-standing setting-board, fully exposed upon a shelf in my study ever since its capture here four nights earlier. Briefly, scientific objectivity swayed the balance against personal indig- nation, as I watched this wasp shamelessly and completely consume an entire dead moth body as big as itself, with a ferociously enthusiastic and noisy determination, and with a masterly skill at circumnavigating the forest of pins. Replete with chewed-up moth, (this doubtless destined for its waiting hungry larval dependants), and leaving scarcely any debris at all, it then made a “bee”(?)-line for the open window. But, just two minutes later, back it came, making a very positive and characteristically pendulous aerial approach towards the next ¢rifolii up from the bottom of the board. . Now, trifolii is always a common enough Noctuid here in N.E. London in August, and in this particular month of relentless dessicating heat, it had become an absolute plague, both as adults attracted to light and Buddleia, and as mature caterpillars swarming locally beneath our abundant waste-ground growths of parched Orache (Afriplex) and Knotgrass (Polygonum). However, this additional hymenopterous assault upon a Setting-board, adorned as always with the fruits of painstaking lepidopterous labours, was sufficient to evaporate any further possible scientific curiosity. Therefore, I am sure that fellow moth enthusiasts will now forgive that sudden and well-aimed right-arm movement which uncompromisingly removed any possibility of such a protein feast being extended to a second course. Our late hero’s just “dessert” proved less than sweet.—Brian Wurzell (3718) DISLIKE OF DARK GREEN FRITILLARY:—I am fortunate in having adjacent to my back garden, a strip of land which provides a breeding area for several species of butterfly. Backing onto the land, in a neighbour’s garden, there is a very overgrown Buddleia, which has been host to most of the usual Nymphalids, as well as Lycaenidae, Hesperiidae, Pieridae and Satyridae. Whilst all these had fed quite contentedly with just the occasional squabble over a flowerhead, the peace was one day shattered by the arrival of a Dark Green Fritillary (Argynnis aglaja L.), a species new to the area. Almost as one, practically everything that could fly, left the Buddleia to chase the ‘intruder’ away. This was repeated several times, with the Fritillary being chased for up to 50 yards. As a result, I had a grandstand view of a marvellous display of flying and gliding. It did eventually manage to settle, but only briefly, and then the chase was on again. Unfortunately, the insect then gave up the unequal struggle and was not seen again. However, my disappointment has been tempered somewhat by the arrival of a colony of the Chalkhill blue AES BULLETIN, Vol. 36 2] — Lysandra coridon Poda), another species new to the area. I should be interested be know if other members have noticed this rather unusual behaviour towards the Dark green fritillary. The dislike of the insect was not confined to any particular group, and such unlikely flying companions as Peacocks, Meadow Browns and Skippers, all joined in the ‘hunt’—Colin Simmonds (5050) ERRATA AND APOLOGY :—The editor regrets that due to a Lapsus in his proofreading, on page 123 of the August last issue, an author’s name was mis-spelt. It should be Paul Selden (4115). WHITE POINT IN HAMPSHIRE:—On the night of 23rd August last year two specimens of Mythimna albipuncta D. & S. were caught by an MV light trap situated at Hayling Park, Hayling Island. One was released and the other sent to the Natural History Museum for verifica- tion and has been incorporated into the National collection.—John Walters. (5904 J) MORE CAMBS CAMBERWELLS:~—Since the migrant records pub- lished in our last issue three further reports have reached us. Indeed Nymphalis antiopa L. seems to have been rather common in Cambridge this year, although avoiding our garden.

BREEDING OF DEATHSHEAD:—On 20th July last year I received half a dozen ova of Manduca atropos L. from Ray Adams, Canary Islands. Only two hatched and one died at the second moult. The single- ton fed up rapidly and pupated on 18th August. I left it in my breeding cage, as thought, for the winter. On 24th September I heard a fluttering noise at 9.00 o’clock in the morning; looked into my breeding cage and found a perfect female Deathshead had emerged, having been only 37 days from pupating to emergence : —C. F. Wilding (4938). [M. atropos is continuously brooded and this is why it cannot survive an English winter. Breeders should note this with foreign stock and always keep them warm. Do not put out for the winter! The related M. sexta Johan. at 28° C takes 35 days from egg to adult—Editor] LIGHT TRAPS AND WASPS:—I have made myself a light trap for moth catching with a black light unit in it. Some mornings when I went out to see what I had caught I found a few wasps in it. Later the numbers got larger. I removed the wasps and wondered what they were doing. One afternoon leaving the top off my trap to allow the contents to escape I saw a wasp catching a moth, killing it, and flying out to a nearby wall and apparently eating it. A few minutes later another would come and so on. I think that the local nest must be relaying the information for free food :—S. Ellis (5659) 28 FEBRUARY, 1977 SPECULATORS BEWARE:—Early in 1976 the Daily Telegraph’s business column was urging stock marketeers to buy rare butterflies as a hedge against inflation. In particular it appears they had in mind the large colourful Birdwings currently advertised at up to £200 per pair. I can think of nothing more likely to suffer a market collapse than livestock. The precedent has already taken place and there has been a complete collapse in prices of many species due entirely to their powers of reproduction. For instance the price of a Clifden nonpareil in 1939 was £5, which let us face it, was equivalent to £50 at least in todays — money. In the 1960’s I offered them free and could not find a taker. Todays price appears to be about SOp to £1.00. Some investment! To take another example, in 1926 a blue coloured Large cabbage white sold for £26 at auction (£260 in 1976 terms). Present price a pound or two. Studying a recent dealers list of varieties, I note that in real monetary terms the prices asked are far below what similar material was fetching at auction between the wars. Butterflies are for Entomolo- gists and should be collected for their intrinsic interest. If speculators wish to burn their fingers however, perhaps we should encourage them, for it is after all the demand that encourages dealers and hobbyists to go in for breeding, as already happened with the South American Morphos and a number of Taiwanese species. This will make them easier and cheaper to obtain: —Editor. | AN UNUSUAL FIND:—After an unsuccessful search in Newball Wood, which is a small wood just outside Lincoln, for Pearl-bordered fritillaries, I came across a male Silver spotted skipper (Hesperia comma. L.) resting on a blade of grass on the very edge of the wood. I feel that this species is now of sufficient rarity to make its sighting worth recording: —A. Crook (5481) UNUSUAL FOOD PLANT OF ELEPHANT HAWK MOTH:—On the 7th August, 1976 I visited the Wonderful World of Nature exhibition at the Old Mill, Kirkby Fleetham, N. Yorkshire and was shown 14 larvae, in various stages both brown and green, which were feeding on a plant of Menyanthes trifoliata L., the Bog Bean, which was growing in the pond. I identified the larvae as those of Deilephila elphenor L. and the foodplant was identified for me by Mr. P. W. Cribb. The larvae were not part of the exhibition, the ova having been deposited on the plant naturally. Although Epilobium hirsutum L., Great hairy willow Herb, was growing in several places around the pond, there were no larvae present on these. As the larvae would obviously not be able to reach land as the plant was surrounded by water, I and the wife of the owner of the place transferred them to the plants of the same species close to the bank. This is the first time I have found this species on any plant other than species of the Willow herbs——A Northern Correspond- ent.

I have also found larvae on Impatiens capensis Meerb. and in Middle- sex its usual Foodplant is Chamaenerion angustifolium L.—P. W. Cribb. THE FUTURE OF THE WHITE-LETTER HAIRSTREAK:— In Britain the White-letter hairstreak (Strymonidia w-album Koch) feeds on species of Elm, Ulmus spp., but chiefly on solitary specimens of the Wych Elm, Ulmus montana With. (=glabra Huds.) It has a preference for large solitary trees though I have found colonies centred on several trees growing in a row and also one or two colonies associated with groups of the Common Elm, Ulmus campestris Mill, (=procera Salis.) and the Cornish Elm, Ulmus stricta Lindl. During the present outbreak of Dutch Elm disease it was hoped that the Wych Elms might be more resistant to the disease and perhaps survive but this year, 1976, I have observed the death of the only large specimen in my part of Middlesex and of several large trees in Buckinghamshire and Oxfordshire which I know to carry colonies of the butterfly. In Gloucestershire, Dorset and other counties in the west of England I also observed that Wych Elms were dying amongst an almost total devastation of the Common Elm. It certainly appears that, in the South at least, the Elm, of whatever species, is doomed and with this loss there must follow the disappearance of yet another of our native butterflies. There are of course other insects dependent upon the Elm, in addition to the Elm bark beetles who are the cause of the trouble, so we may see several insects disappear from our countryside. Two moths which I have always found on the Wych Elm are the Clouded Magpie, Abraxas sylvata Scop., and the Brick, Agrochola circellaris Hufn.—P. W. Cribb (2270) CLIFDEN NON-PAREILS IN NORFOLK:—No less than seven Catocala fraxini L. migrated to Norfolk last September. One of them was shown live on the BBC programme “Look East”—Editor. BEWARE THE SHARKS: —We have received an unsolicited catalogue from a firm calling themselves “The Armado Aquarium” based in Singapore and offering some 500 Malaysian butterfly and other insect species for sale, to be paid for in advance. The prices appear to be a curious mixture of Malaysian and United States Dollars. Most of the buterflies are named trinomially and there has been a great increase in sub-species “Malayana’! Apart from butterflies it is a little difficult to understand exactly what they might be selling. What for instance 1s 30 FEBRUARY, 1977 Attacus atlas Malayensis? It is sold by size, from 6 cm to 12 cm ata price of 54p to £1.80. All my bred A. atlas L. seem to be greater than 12 cm wingspan and I do wonder how such minute specimens are produced! Next we come to that very interesting group of moths, the Argema mittrei Malayensis complex consisting of Hawkmoth Deilephila elpenor Malayensis and Gypsy moth Porthetria dispar, both of these being priced at £1.20, with Tiger moth Arctidae at 85p to complete the trio. Under Lunar Moth, Saturniidae, we have but one species, sold again by size, from 10 cm to 18 cm at a price of from £4.20 to £7.20. This, lo and behold, is none other than that familiar old nocturnal friend of ours, omitted from all copies of the Silkmoth Rearers Handbook with obvious intent, “The Shark”, Cucullia Aneemisiae (sic!) Malayen- sis —Editor. PONDS:—In the editorial of our last issue I drew attention to the fate that is overtaking ponds. There is indeed moves afoot to save them. The passage sequiter is reprinted from Habitat Vol. 12 No. 9. (Sept. 1976). “The Director of the Save the Village Pond Campaign has said that the drought which has been drying out ponds in Britain could also increase their conservation by focusing attention on the need for ponds as small but local supplies of water.” He cites such examples as emer- gency watering of farm stock, fighting small grass fires and watering allotments. The drought also provides an opportunity to clear out the ponds, as their level is low enough to remove rubbish more easily and cheaply than usual. Normally people would not be encouraged to remove rubbish at this time of year as pond life is still active. A number of projects such as restocking of ponds once the water returns, replanting of pond plants and removing some of the silt layer, were suggested by the Village Pond Campaign.” MIGRANT DEATHSHEADS :—On 11th August, 1976 I found a fully grown larva of Manduca atropos L. in a potato field near Haverford- west, Wales. The caterpillar pupated within three days and the moth, a female, hatched on 20th September, but unfortunately failed to fully expand its wings.—Nicholas Platt (5433 J) PLANT-INSECT RELATIONSHIPS MEETING:—The Linnean Soci- ety of London and the Botanical Society of the British Isles are organis- ing a joint conference from Thursday, 14 April - Sunday, 17 April, 1977 on the subject of Plant-Insect Relationships with Special reference to Pollination. Speakers have been invited from USA, Canada, South Africa, Israel and a number of European countries, and papers will be given on subjects as diverse as the detection of flowers by moths, pollina- tion on the sea-shore and flower mimicry. Venue is the University of Newcastle-upon Tyne and further details can be obtained from Mrs Mullin, 43 Woodstock Avenue, West Ealing, London, W13 9UQ if a 9” x 4” sae is sent. The programmes and application forms will be sent out in January 1977. AES BULLETIN, Vol. 36 31 A SIMPLE METHOD FOR SETTING FLIES As anyone who has tried will know, the setting of flies poses some very different problems to those encountered in setting Lepidoptera. One of the major difficulties encountered is that of securing the legs efficiently, while at the same time leaving space to manipulate the wings into the desired position. It will also be found that if any type of conventional setting board is used, the legs cannot be spread into natural positions due to the narrowness of the groove required for setting the wings, and if a wide groove is chosen the wings are difficult to secure. With these problems in mind I set out to find an easier method of setting those flies that are large enough to be pinned. After a period of experimentation I developed the following method with which I have set many specimens with complete success. The fly having been pinned, the first requirement is a block of expanded polystyrene. The specimen is then placed in the centre of the block and the legs manipulated into the desired positions with a setting needle. It will be found that in most cases the natural gripping nature of the feet will hold them firmly to the polystyrene and a securing pin is only rarely necessary. Before adjusting the wings, it is often helpful to place a pin each side of the body in order to prevent it from twisting when the wings are brought forward. A stage for holding the wings is easily made using clear plastic strip. That from the collars of new shirts is ideal. Two pieces of strip about 1” x 4” are placed together and a pin pushed through them both as shown in the illustra- tion. Two of these stages are made, one for each wing. To set the wings, one of the stages is pinned in front of the insect with the clear strip pointing backwards. The two pieces of strip are held slightly apart with a needle while the wing is positioned between them. Provided that the part of the strip that the pin passes through is near enough to the front edge of the wing, the sandwich action of the strip is strong enough to hold the wing securely in place. Because the wing can be seen through the plastic, the folding over of any parts of the wing is easy to see and to remedy. The other wing is set in the same way, and any final adjustments are easy to make by simply parting the pieces of strip and moving the wings with a setting needle. Having left the specimen to dry for a suitable period, removal from the polystyrene block poses no problems. The stages for the wings are re- moved by twisting them sideways until the wing slips out, parting them slightly if necessary. The insect is then carefully pulled away from the block, having removed any securing pins of course, and will come away easily, the gripping power of the feet not acting so strongly to this upward force. No problems have yet been encountered in the way of ‘drooping’ on the setting board or difficulties in removal, and the spect- mens set in this manner have a nice ‘natural’ look. With a little practice 32 FEBRUARY, 1977 A set specimen of Syrphus ribesii View from above Cellophane strip View from the side AES BULLETIN, Vol. 36 33 this method is very quick and a large fly can easily be set in 5 minutes or so. I have not tried out this method on any other orders than Diptera yet, but feel that it may be suitable for many other orders such as Hymenop- tera or Orthoptera, and members might find it interesting to try it out on such specimens. I hope this article proves useful to members, and that possibly the simplicity of this very cheap means of setting might possibly encourage interest in the more unusual orders of the insect world. I would be very happy to help anyone who encounters any problems while using this method. L. H. T. LARGE (4424) (The editor thanks Mr. Richard Lewington for the illustration) CROATIA AND SLOVENIA—JUNE 1975 (Continued from Vol. 35 page 164) We started early on the Sunday, 22nd June, and drove via Karlo Vac and Novo Mesto towards Lubljana. Unfortunately we missed our road and found ourselves on a secondary road heading for Zagreb. However we decided to stay on it and strike the Autoceste from Zagreb to Lubljana. On the way we saw Storks nesting on the top of telegraph poles and several soaring over the plain. The autoceste is a straight road of a two vehicle width no cross roads so that a good speed can be maintained. Near Otocec we stopped where a huge forest flanked the roadway on each side. Of mixed deciduous trees it seemed dense but we found a glade which led away from an animal culvert which passed under the roadway. The sun kindly came out and it was hot and very humid. The glade was alive with Heath fritillaries, M. athalia, large and well coloured. Among them were a few Melitaea diamina Lang and N. ilicis. Suddenly a butterfly like a White admiral circled down from the Hazel bushes and into my net. It turned out to be Neptis sappho Pallas an eastern species which has the same food-plant as L. morsel, the Vetchling Lathyrus verna. I had taken N. rivularis Scop. which is very similar in N. Italy some years ago and this was my first, and only, specimen of its cousin. The pathway had many big puddles ringed with deer slot marks and in them were dozens of Yellow-bellied toads in various stages of growth. I walked back towards the tunnel under the road and disturbed a large butterfly which raced off across the road and then returned to circle round me. I saw the flash of royal purple and netted a freshly emerged male of Apatura ilia L. We would have liked to have stayed longer here but we still had a long and unknown journey ahead of us so reluctantly drove on through the forest lined road to Lubljana and out to the north where we could see the outline of the mountains in the distance. Heavy rain started to fall and did not stop until we reached the industrial town of Jesenice which stands at the end of the valley leading up between the Julian Alps and the Kara- 34 FEBRUARY, 1977 wanken Alps, the latter forming the frontier with Austria. At the end of a winding road we drove into the village of Kranjska Gora where we had booked rooms at the Hotel Prisank. In the evening sunshine the Julian Alps to the south of the village filled the landscape with the sun sparkling from the snowfields round the peaks. The Karawanken Alps are much lower and well wooded, while the peaks of the Julian Alps rise to 2,600 metres with Triglav the highest. We were still having to push start the car as the battery did not appear to hold the charge and with the friendly help of fellow guests we Started next morning up the Vrsic pass which leads up into the Trente valley before passing at about 5,000 ft. over the col towards Trieste. This is the home of two Erebia species, E. calcaria Lork. and E. stirius Gdt. but we guessed we would be too early for both in this late season. On the way up we encountered three large coaches and these had to take three bites at each of the hair-pin bends of which there are twenty-three on the way up. The road passes through flowery meadows above the river, by a lake and then up towards the snowy slopes. The metalled road peters out well before the col and the rest is a stony dirt track. We stopped and explored the slopes from which the snow had only recently departed and found dozens of Pieris napi bryoniae Hubn. flying up and down. The Spring butterflies of England were just on the wing, the Grizzled skipper, Pyrgus malvae L., and Erynnis tages L., the Dingy skipper, and several Orange tips, Anthocaris cardamines L. and some male L. sinapis. It seems obvious that we were too early for much else and drove down towards the village. This was nearly my last drive. With the battery being flat I inserted the ignition key but did not turn it. Taking off the hand brake the car rolled forward and as I turned the steering wheel the wheels locked (a device on the WG to prevent theft) and we went straight across the narrow road and over the edge. I slammed on the brakes and by a miracle there was a thin strand of wire along the edge. This caught under the mudguards as we went over and there we were with the car teetering over the edge. We managed to crawl out onto the road and eventually a car came up the pass with a Swedish driver who had a tow rope in his boot. This we tied to the back bumper and with the help of two farmers who had climbed up the slope we managed to get the car back onto the road, none the worse for wear though we both found the experience traumatic. Somewhat subdued we spent the rest of the morning collecting in the meadows above the village where we found carpets of Columbine, Aquilegia sp., and Orchids of several species. The Pearl bordered fritillary, Clossiana euphrosyne L., and P. hippothoe were common and with them lots of L. sinapis. In the afternoon we tried the other side of the valley, driving up the Wurzen Pass which leads over into Austria. We found the slopes here almost devoid of butterflies though rich in Orchids—white and mauve forms of the Fragrant, pink Pyramid mixed with red and the Early purple. AES BULLETIN, Vol. 36 35 On the following day we decided to drive back down the valley and try the woods and meadows, hoping that more might be on the wing there. The battery trouble had been resolved as the night before I had rung the car hire firm at Lubljana and a new Beetle had been driven out to us. The valley all the way down is quite beautiful with flowery meadows and woodlands. During the next three days we explored them thoroughly down through the village of Gozd and right beyond Jesenice. We disturbed several roe deer and some large hares during our wanderings and took several new species of butterfly. Amongst these were an interesting aberration of the Adonis Blue—it was a female, half of which was typical and the other ab. ceronus Esp. Along a deserted railway line we took H. alciphron Rott. and Aricia allous montensis Verity., and several specimens of the Chequered skip- per, Carterocephalus palaemon Pall. These last were in a little woodland glade beside the railway and were flying with the Duke of Burgundy fritillary. Melitaea cinxia L., Brenthis ino Rott. and B. hecate were the commonest small fritillaries and the only large one seen was Fabriciana niobe eris Meig. flying fast over the meadows. The meadows could not be said to be rich in butterflies, the reason almost certainly being the shearing which was already taking place—scythe and small power mowers cut them very close and the grass is hung on wooden frames to hay. The weather continued to be unsettled with storms most even- ings and wet grass next morning but there was sufficient sunshine to bring insects on the wing so that we were able to assess quite fairly the insect population. Below Jesenice I took a short series of Coenonympha iphis (=glycerion Bork.) Schiff. flying with C. arcania. and on a grassy bank there were hundreds of M. galathea and Coleridge caught one which had the forewings almost totally black. The beautiful blue, Plebicula dorylas Schiff., was just emerging and I took one male C. dia L., several Q. quercus and some Narrow-bordered bee hawks, Hemearis tityus L. These last were buzzing about the flowers and were hard to pick out from the Bumble bees. Searching for larvae, I found those of M. athalia feeding on Yellow rattle, Rhinanthus sp., and several larvae of L. coridon on clumps of H. comosa on which Colias australis females were depositing ova. There were a few E. medusa and G. rhamni in the woodland clearings and in a swampy area we found a lot of Purple- edged coppers flying. I collected several stems of Dock, Rumex sp., on which eggs had been laid but these subsequently produced Heodes tityrus subalpinus Speyer so must have been laid some time earlier as we did not see it on the wing. The railway line gave us a nice feast of wild strawberries but the wild raspberries were still in flower. On the 26th I decided to drive up to the top of the Vrsic pass despite some misgivings after our previous experience. Right on top of the pass the view is striking—fields of snow with clearings of grass, heather and Alpenrose above, and below the winding hairpins of the road. People were still skiing as I climbed up a grassy gully above the road. P. bry- 36 FEBRUARY, 1977 oniae was everywhere and then I saw an Erebia. After a breathless chase I netted a male E. pandrose Berkh. and higher I found them very commonly. The race is very large and handsomely marked. Large flocks of Alpine Chough floated above my head, their raucous cries and sharp whistles breaking the silence. In the sunshine it was quite warm but as soon as cloud covered the sun the temperature dropped suddenly and a cold wind blew off the snows. Half way down the pass is a wooden Chapel built during the 1914-18 War by Russian prisoners of war in memory of 400 of their number who died while building this pass. There were flowers on the altar above which was a group of icons. In the afternoon we drove out to Podkoren on the Italian frontier and up a stony track below some impressive ski jumps. We saw a large black snake cross the roadway towards a lake, probably a large dark form of the Grass snake. There were now dozens of L. sinapis on the wing but little else. On the 27th we woke to clear skies and the promise of a really hot day so decided to venture further than before, driving down through Jesenice. Beyond the town we turned off back into the Julian Alps to the town of Bled. Just outside the town there were large areas of pine woodland with grassy clearings. M. athalia was again very common and a lot of Ascalaphids buzzed about over the grasses catching flies: As I walked along a glade a large brown butterfly flapped across in front of me and I managed to net it. It was a new species to me, the Woodland brown, Lopinga achine Scop., very like the Speckled wood, Pararge aegeria L., in its habits. I also took one female Strymonidia spini Schiff. and Coleridge saw A. ilia. We drove into Bled and stopped by the vast lake in which there is an island with a church. In the deep water beside the bank we saw four huge Tench playing amongst the weeds; they must have been about 7 lbs. apiece. The road beyond the town winds through flowery valleys to another large upland lake, Bohinjsko Jezero, about 13 km. further on. Here we stopped above the lake where a wide river flows out of the lake below a bridge. There is a church here to St. John the Baptist with huge murals on the outside wall and inside a gory statue of St. John minus his head which is on a platter. The surface of the shallow part of the lake below the bridge was covered with a huge shoal of fish, apparently spawning. They appeared to be Chub and Roach and many were very large. It was extremely hot and we managed to buy ices in the village before driving back to collect among the meadows down the valley. These were not rich in insects despite the masses of flowers—some C. australis, L. bellargus, P. icarus and C. semiargus. I did find some half grown larvae of G. rhamni L. on a Rhamnus bush. A storm was now threatening above the peaks so we drove the long journey back to our hotel to arrive as it broke with crashing thunder and torrential rain. The next day was our last at Kranjska Gora and we made an early AES BULLETIN, Voi. 36 37 start to drive down to Lubljana. It was a dull morning after the storm and we stopped to explore some woodland about 20 Km. short of the City. M. athalia were sitting about on the grasses and on the young Firs I found several resting N. ilicis of both sexes. There were also some very large L. idas which we picked from the grasses. A drizzle drove us on into Lubljana where we had a room for the night at the Grand Union Hotel. Right in the centre of the City, it is quite luxurious and we were entertained at dinner time by a large group of American guests who were of Slovenian origin and were touring their native land singing American and Slovenian songs. At 7 p.m. another huge storm broke and this lasted all night with rain gushing out of every gutter and the roads awash. On the Monday morning the storm was still with us as we scrambled into the car and drove off towards Zagreb. Surface water was washing debris off the mountain slopes and the roads were quite difficult and the rain almost blinding. We drove the 80 odd miles to the outskirts of Zagreb before stopping and at last got beyond the storm but ran into the worst traffic jam I have ever met. It took us nearly two hours to travel 4 km. but at last we got beyond the City and reached the airport with plenty of time to spare. We were lucky as when eventually our BAC 1-11 did arrive, over an hour late, the British Airways had overbooked by sixteen seats and the late comers were left behind to travel next day. Flying into the setting sun we climbed into the storm clouds and did not see anything below us again until we came out of cloud over the Belgian coast to land at Heathrow at the start of a heat wave. During our trip we had recorded 74 species of butterfly and despite quite a lot of bad weather had been able to see some wonderful country, photograph many rare flowers and add another area of Europe to our travel map. P. W. CRIBB (2270) NOTES ON BRAZILIAN LEPIDOPTERA Gonepteryx chlorinde, Godt. The elegance of G. chlorinde is due to its delicate colouring, shape and size. It has a satin-white upperside, relieved by a pale yellow patch on each forewing, while its verso is the palest of pale greenish white. The curves, angles and points of its wings give it a similarity in shape to the Brimstone, and its 34 inch spread make it one of the largest of the Pierid family. It is a very swift high-flyer and dodges at rapidly changing heights from tree to tree, flower to flower, always, however, in fairly open areas. It is very fond of the flowers of Cassia, Hibiscus and Bougainvillea, and where all these are available it settles only momentarily on the blooms of any of them before hurrying off urgently to sample the others. If, in fact, chlorinde has a preference, it appears to me that 1! may be 38 FEBRUARY, 1977 any of the varieties of Hisbiscus flower, whose yellow stamens seem to tempt it to loiter longer than it is wont to do at the other flowers. This butterfly is not uncommon in some years and usually appears during the period marking the end of the wet season and commencement of the dry weather, but during some years with quite normal seasons it is extremely scarce for no apparent reason. I have seen chlorinde in various regions of Brazil—North, North-East and South-East, from sea-level to 3500 feet—and have sometimes come across it in quite unexpected places. One, in 1948, near the town of Sertania in the “Sertao” (or Hinterland) of Pernambuco, at about 1800 feet, after recent rains had freshened the country side (which in that region is very arid in the dry season), and left it lush and green, I came upon large numbers of fresh-looking chlorinde flying about aimlessly and in apparent confusion (I have sometimes wondered if this was the result of a mass-hatching of large quantities of chrysalides, and whether this was the starting point of a migration). Another time, (in 1956, in the latter part of a season of no rain), on the slopes leading to the town of Triumfo perched on a mount at 3,400 feet, whence copious springs gushed out to form, lower down, a “brejo” or oasis in this arid part of Pernambuco, chlorinde, together with other Pierids and several species of Nymphalids, were very much in evidence. Yet another un- expected sighting of chlorinde was in Alagoos beside a tributary stream of the Rio Mandahu, when my glance was attracted by a frantically waving, tall grass stalk, on a dripping fern and grass-covered cliff. On the tip of this stalk, there was a fine chlorinde. I was surprised, as this was not the type of terrain where chlorinde was likely to loiter, there being no flowers at all. However, it was soon evident that this butterfly had probably not intended to dally there but had been simply flying past and had bumped into a spider’s web. And the spider was already on hand, busily and efficiently wrapping it up with sticky threads.... Phoebis philea L. The male of this species with its orange-flushed yellow wings is one of the most handsome of butterflies. It spans 3 inches. From near the costal nervure of each forewing a patch of bright orange splashes across the cell. The hindwings, of the same refreshing daffodil-yellow are also tinged with orange in a wide suffusion along the outer margins. The slightly smaller female has, perhaps, a richer colour pattern than the male. The forewings are devoid of orange markings. They are of a deeper yellow, brown freckled and brown tipped. The yellow hind- wings have a pinkish tinge with a wide red-orange splash at the outer margins. The flight of both sexes is very rapid and erratic; usually oscillating at heights between 10 and 25 feet. The larvae feed on Cassia alata, and C. fistula (known popularly, in AES BULLETIN, Vol. 36 39 Brazil, as “Chuva de Ouro”, or Golden Rain because of its delightful cascades of yellow blooms). Not only the caterpillars, but the angular chrysalids, too, are hard to find, even when fairly numerous, so well does their colouring blend with the light-green foliage of the food-trees. The butterflies, male and female are partial to the yellow Cassia flowers and hover fussily about these blooms, returning to them repeatedly after sampling other flowers. The females also like the flowers of Poinsettia (Euphorbia pulcher- rima), Wild Lantana and Bougainvillea, but the males are less often to be seen on these flowers. And, whilst I have often seen a female hovering about the “Flambayante” trees which abound in Alagos and Pernam- buco, and revelling in their fiery red and orange blooms, I have seldom noticed a male amongst these glorious flowers. The gnarled and stunted 20 ft. high “Caja” or Cashew-nut trees (Anacardium occidentale) growing wild in the sandy coastal areas of Pernambuco, have an attraction, with their pink- and-yellow blossoms, for both sexes of philea which vie with numbers of small bees, Buprestid beetles and a few day-flying moths in sampling these flowers. In a Para forest, however, I once came upon another species of “Caja, growing straight and tall to over 45 feet. The foliage was not at all dense, and it was possible to see the glint of bees’ wings sparkling in the sunshine, amongst the blossoms. But no philea were in evidence. I suppose this was because his butterfly prefers more open spaces, and perhaps the tree was too high for its liking, for quite close by, near the fringes of a clearing, I spotted four or five of them in the course of the forenoon. P. philea appear in their largest numbers towards the end of the season of heavy rains. In a country as vast as Brazil the periods of this season vary considerably in different regions. Thus, in Minas Gerais the incidence of this butterfly is greatest in February and March, where- as in Alagaos and Pernambuco it is most often seen during May, June and July. Over many years in the North-Eastern and South-Eastern regions I have come across philea at altitudes ranging from sea-level to 4,600 feet, and think that altitude has little or no influence on the appearances of this butterfly (up to 4,600 feet at least). P. philea prefers the early forenoon for flight, when the sun is begin- ning to get hot, while the vegetation is still glistening with dew and moisture from the morning mists. Towards midday it tends to disappear from the air, but appears again for a short time some two or three hours later. At any hour of the day, however, in open areas, if the sun is shining, the male especially may be found with other Pierids and a few other butterflies, on wet ground at the margins of the lakes and streams. This is particularly so in places where the ground has been churned up by cattle into muddy, polluted slush. In such places, and also on wet, lime-impregnated soil near limestone cliffs and in the vicinity of concrete 40 FEBRUARY, 1977 constructional work, I have often observed them with companions of other genera engrossed in the pastime of sipping moisture from the soil Sarmentoia phaselis, Hew. At Cera Grande, on a marshy plain near the left bank of the Riodas Velhas, in the municipality of Pedro Leopoldo in Minas Gerais, there is a rugged grey limestone rock of enormous proportions. It is 1,200 feet by 300 feet and looms vertically to a height of 130 feet. In this limestone outcrop there are many caves, some of which had once served as shelters for a forgotten aboriginal tribe of Indians, as coloured rock- drawings and other remains testify. Some of the caves are located up in the cliff face; others are lower down and some have, in recent times, been inundated, as evidenced by much dried silt. Due to the lime which impregnates the soil, the surrounding Terrain supports a luxuriant secondary forest and dense brush, interspersed with patches of tall grass and a very virulent species of stinging nettle, which completely conceal some of the cavities. Numbers of parrots (Psittacus virescens) and many small monkeys desport themselves in this area; and butterflies, too, abound, especially towards the end of the wet season which lasts from October to April. Morpho achilles L. is plentiful, as are various Heliconids and Pierids, and Catagramma sorana Stoll, among many other Nymphalids, etc. Within some of the lower caves, on three separate occasions—in 1964, 1965 and 1972, I saw several Hesperiids and secured a few speci- mens. Previously, in 1962, I had seen some of the same species in the dry, cavernous entrance “hall” leading into the beautiful grottoes at Maquine in the Municipality of Cordisburgo, also in Minas Gerais. All these Hesperiidae were Sarmentoia phaselis. In each case they were at rest on dusty or silt-coated stalactites or stalagmites or on the walls of the cavern, in the half-light near the entrance. In 1970, on the shore of a reservoir known as the Lagoa dos Inglezes, in the Serra da Moeda in Minas Gerais, I made a lucky fluke-capture of a specimen of S. phaselis. The red iron-oxide soil was dotted with many “ant” hills—really the nests of termites (Cornitermes sp.). One of these, a 5 ft high mound, had an 18-inch-diameter hole in its base, where armadilloes (which are very partial to termites) had dug deep into the almost rock-hard mound. Hoping to see an armadillo emerge. I had flung a handful of gravel into this hole, whereupon, to my surprise, an extremely fast-flying butterfly shot out and into the net held in my left hand. This was a phaselis. Apart from the cases recounted above, I have never caught, nor seen, another specimen of phaselis and so am inclined to think that this butterfly favours dry, rather gloomy cavernous places in which to repose. All these specimens had a wing span of 1-14 inch. In colour they are basically light-brown. There are light small well-defined, irregular, AES BULLETIN, Vol. 36 41 semi-transparent whitish marks on the forewing and seven ill-defined dark brown dots (or tiny blotches) on the hindwing. The body is rather furry. Pachylia syces, Hubn. In Brazil, the streets and squares of many towns and cities are heavily arborized to alleviate the tropical glare, and of course, for the sake of shade. One of the trees most admirably suited for this purpose is Ficus benjamina, which, with its thick evergreen foliage lends beauty to many a street and square. F. benjamina is the principal food tree of the caterpillars of the large hawk-moth, Pachylia syces. These caterpillars also feed on the leaves of the Jack-fruit tree (Autocarpus integrifolia) and on many species of fig other than benjamina; but they are generally to be found on benjamina which is the food-tree abundantly available to them. Until the final instar the P. syces larvae are light green with two parallel white stripes along each side; with thin narrow bands between the segments. The head and short stiff tail are of a darker shade of green. Even when their droppings make it obvious that they are feeding on a certain tree, it is extremely difficult to locate the caterpillars because of their colouring, aided by the density of the green foliage. Immediately before pupating the caterpillar becomes black, and the bands between its segments take on a greenish hue, while the head turns red. At this instar, the caterpillars, now some 44 inches long and near 3 inch thick at the middle, crawls down from the food-trees and searches for a convenient place in which to pupate. At this stage, on various occasions, in the States of Paraiba, Pernambuco, Alagoos and Minas Gerais, at all altitudes up to about 4,000 ft. I have seen numbers of these caterpillars roaming about on the streets and pavements, always in the season when most of the heavy rains have passed. Pupation takes place in loose soil or amongst the dead leaves accumulated in the nooks and crannies between or near the roots of convenient trees in the vicinity. A flimsy web or cocoon of coarse silk sometimes encloses the 25 inch dark-brown chrysalis, but more often there is no covering whatsoever. The adult P. syces emerges some three weeks later, and may be seen at night, alternately orbiting the street lamps and swooping off into the gloom, looking like a bat; and in the early morning, at rest on a nearby wall, or clinging to the dewy leaves of a garden plant; or on the trunk of a benjamina fig tree. The appearance of this Sphinx moth is unprepossessing—something of an anti-climax after-seeing the handsome caterpillar from which it developed—being dark brown in colour, relieved only by some hardly discernible paler markings and one clear-cut pale patch on the coistal border near the apex of each forewing. The outer margins of both. upper and lower, wings are serrated. The body is gross and its upper- side is brown with the hint of a greenish sheen in the abdomen, while 42 FEBRUARY, 1977 the underside is fulvous. P. syces is a swift strong flyer, with a wing- span of 35-45 inches. The wings of the male are slightly narrower than those of the female, otherwise their general aspects are similar. Terence C. Hanson (5242) NOTES ON THE LEPIDOPTERA OF THE ISLE OF LEWIS While camping at Uig Sands, Isle of Lewis (Outer Hebrides) with the Schools Hebridean Society, I made a brief survey of the lepidoptera around the campsite. The dates were from the 12th to the 22nd of August, 1976, and the weather was hot and sunny, although windy on some days. Most of the land around the campsite consisted of dunes, with a few outcrops of rock, the most abundant vegetaticn was Marram Grass, although plenty of other plants were found. There were several large patches of Ragwort, which attracted much lepidoptera to its flowers. BUTTERFLIES By far the commonest butterfly was the Meadow brown (Maniola jurtina, L.) which could be found among grass on the dunes. Also among the dunes could be found the Common blue (Polyommatus icarus, Rott.) This, however, was less common than the Meadow brown, and I only saw two (one of each sex). Several Red Admirals (Vanessa atalante, L.) were seen, and this butterfly seemed to like the flowers of Ragwort. On several days, I saw one fluttering over the yellow blossoms, and when feeding, they were quite tame, and I could get within several inches of them. Their larval food plant, Stinging Nettle, was not abundant, but several patches grew nearby. While visiting a small village about a mile from the campsite, I saw a White butterfly. As I did not have my net with me, I could not make a certain identification, but it was either a Small white (Pieris rapae L.) or a Green-veined white (P. napi L.). Three other species, the Large white (P. brassicae, L.) the Small tortoiseshell (A glais urticae, L.), and the Gatekeeper (Pyronia tithonus, L.) were seen by other people on the campsite. However, I am inclined to disagree with the record of the Gatekeeper, as it is not often found so far north. MOTHS Nine species of moths were found, two of them belonging to the family Geometridae, and the rest to the Noctuidae. The commonest Geometrid was the Common carpet (Epirrhoe alter- nata Miill.). The specimens caught were on the sub-species obscurate, south. The other Geometrid was caught on my last day at the campsite, and I think it was a Purple Bar (Lyncometra ocellata, L.). The markings AES BULLETIN, Vol. 36 43 ee were the right shape, but they were more black than purple. However, its food plant, Lady’s bedstraw, was plentiful, so as far as I can tell, _ the moth was a Purple bar. I found nearly all of the Noctuid moths on or around the flowers of Ragwort. Several species could be found on this plant throughout the _ day. The two commonest moths were the White-line dart (Euxoa tritici, L.) and a species of Ear Moth (genus: Hydraecia). These could be found in numbers on Ragwort flowers. A few Large yellow underwings (Noctua pronuba, L.) were found, mainly on Ragwort. Another quite common moth was the Antler (Cerapteryx graminis, L.). This pretty little moth was another visitor to the Ragwort. Three other species were found less commonly. Two Deep-brown darts (Aporophyla lutulenta, Schiff.) were found on Ragwort, both of the dark form Juneburgensis, Freyer. One Common rustic (A pamea secalis, L.) was found, although on reflection this could have been a tatty Ear Moth! Finally, one Pale mottled willow (Caradrina clavipalpis, Scop.) was found. Martin Harvey (5772 J) SOME NOTES ON CONOCEPHALUS DISCOLOR (ORTHOPTERA: TETTIGONIIDAE) Conocephalus discolor Thun. (the Long-winged Cone-head) is a small bush-cricket with fully developed wings. It is usually a green colour with a brown dorsal stripe, although all brown individuals have been seen. The fore wings are also brown and the hind wings extend slightly beyond the fore wings. In the female the ovipositor is long and slightly upcurved, and in the male the cerci have a tooth on the inner surface. C. discolor is always found close to the coast and is quite common on waste ground in Portsmouth, Unlike most British bush-crickets it is active by day, moving rapidly if disturbed. During the summer of 1976 I obtained a number of individuals and observed a number of aspects of their little studied life history. Due to the possibilfty of canabalism, individuals were kept in separate gauze topped jars with 1 to 2 inches of sand in the bottom. Initially grasses found in the area of capture were provided for food but this did not seem very successful. For the rest of their period in captivity the bush-crickets were fed on various insects but mainly blowflies which were captured daily. They appeared to survive quite well on this purely Carnivorous diet eating 2 or 3 flies per day. Many insect songs have been an ultrasonic component, and in_bush- crickets the sound is often mainly in the ultra-sonic range. This is true 44 FEBRUARY, 1977 for C. discolor where sound up to 90 kHz. have been recorded. The song of the male is high pitched and faint to the human ear and consists of continuous bursts of sound. Singing began in the morning and often continued well into the night. As in other species there was short maturation period before stridulation commenced. One male, which was captured as a nymph, first sang four days after becoming adult. Prolonged stridulation began the following day. There was also a brief period during which singing ceased after a successful mating attempt, but this lasted only a matter of hours. Similarly there was a maturation period in the female which lasted slightly longer than that of the male. In two females captured as nymphs, the maturation period lasted six and nine days after becoming adult. Unlike the males, there was no return to a sexually receptive state after mating. However this may have been due to the death of the females within three weeks of mating. Very little mating behaviour is shown ey this species. When males are in a receptive state they stridulate and receptive females approach stridulating males. Mating itself is a short affair lasting only 10 to 15 minutes after which the sexes separate. The body of the spermatophore can be seen on the abdomen of the female after mating, and this is usually eaten by the female. Egg laying began the day after mating and was then continuous but the numbers laid fluctuated. The eggs were cigar shaped, about 5 mm. long and a pale brown colour. Unlike grasshoppers, bush-crickets lay their eggs singly, in most cases in crevices in vegetation. This can make it rather tedious when it comes to searching for the eggs especially if a daily check is kept on egg laying. To overcome this problem I have devised a simple but effective device. It consists of a number of poly- porous strips (as used for staging) held together securely but not too tightly with an elastic band. The female will then be able to insert her Ovipositor between the strips and deposit her eggs which can easily be collected. Using this device I was able to keep a daily check on the egg laying of C. discolor. Most eggs were laid soon after mating, the numbers laid per day declining thereafter. Days on which no eggs were laid became more frequent as time progressed. Of the four females observed the maximum total number of eggs laid was 59 and the minimum was 27 (average= 42). The average number laid per day was 2.7, the maximum laid in one day was 16 eggs. D. Janssen (5585) REFERENCES RAGGE, D. R. (1965) Grasshoppers, Crickets and Cockroaches of the British Isles. Warne.

Carcasson, pp 30, 11 plates, tp-+index. 1975. small crown 4to. E. W. Classey Ltd., Farringdon, Price £1.80. This publication is a reprint with the original illustrations, but re-set type, of the author’s paper first published 1960 in the Journal of the East African Natural History Society. It is a great pity that the re-set type has been done by a non-registration typewriter, as a result of which the text looks like a xerox reproduction of a typed manuscript. The uni- form lettering makes the text confusing to use as does the inconsistent use of underlines, applied to countries (But only under “RECORDS”!) sub-species, and, sometimes, families: e.g. Acraeidae on page 19. The illustrations on the plates are black and white drawings by the author. The facies of Swallowtails do in fact lend themselves to this type of diagram and the paper they are printed on is of sufficient quality for any owner to do his own colouring on the illustrations. For a variety of reasons, Africa appears in the past to be the least well served continent in respect to Entomological publications. This is now being put right and the author of the present work obviously has a good grasp of his subject and it is a pity that, since the now sixteen year old article was to be re-typed, the opportunity was not taken to correct previous errors and include additional material. As a concise guide, bibliographical reference, and identification key to, the Swallow- tails of Uganda, Kenya and Tanzania, this booklet is of inestimable value and should be of use to all interested in African butterflies, in spite of its faults. SRG AES BULLETIN, Vol. 36 51 GENITALIAS (ANDROPIGIOS) DE LAS ZYGAENAS DE LA PENINSULA IBERICA, by Dr. Fidel Fernandez-Rubio. Published by A.E.P.N.S. 1975 pp. 32, 26 of which are b/w photographic plates. This is the first of a series of publications planned by Spanish ento- mologists to list and illustrate the genitalia of the Iberian Lepidoptera. _ It forms part of the great out-pouring of work from that area now taking place due to the enthusiasm and dedication of greater and greater num- bers of Spaniards towards the subject of entomology. This booklet consists of a series of photographic plates of the genitalia of the Iberian Zygaenidae. There is a very brief introduction and a list of the illustrations, which consists of a general preparation and an enlarged view of the aedeagus. As a general reference work to anyone trying to identify holiday captures this booklet is of use. We would however like to have had a few words of explanation, pointing out differences of closely allied species, and, typographically, we would ask that future editions and publications in this series, have the pages numbered. The booklet is well printed on good quality paper and is apparently sent free on request to interested persons. BOCG. GENITALIAS (ANDROPIGIOS) DE LOS ROPALOCEROS DE ALAVA Y SU ENTORNO IBERICO. PARTE 1. LYCAENIDAE. By Dr. F. Fernandez-Rubio. Published by A.E.P.N.A., Seccion de Cien- cias del Consejo de Culture de la Excma, Diputacion Foral de Alava, Victoria, Spain, 1976 pp 78, 71 of which are b/w photographic plates. Price not known. This is the second of the series of booklets portraying the male geni- talia of Iberian Lepidoptera. It consists of a brief introduction and photographs of dissected genitalia (male) of the Lycaenidae. The plates are 64 x 4! ins. but scale of magnification is not indicated. The pictures are very clear but the work would have been much more useful to the student had there been notes with the pictures indicating the salient features to look for when separating the species where superficially there appears to be little difference in the armatures. This is certainly a book which will be of use to those who include the butterflies of Europe in their interests and will help in more positive identification of some border-line cases. PWC.

Price. £2:50: This is yet another of the now all too numerous small books on the market dealing with but a tiny selection of Europe’s (or Britain’s for that matter) insects. There is perhaps little to choose between them and most are suitable as a brief introductory present for a parent or friend to give the tyro entomologist. The plates really are quite reasonable, but we must query the useful- ness of such small (that is to say natural size) representations of micros such as Nepticulids. The figured species are described and discussed in the text with details of distribution, habitat and life-history. There is a brief introductory chapter and some of the very confusing nomenclature used may be explained by referring to the bibliography which largely consists of books originally written 50-100 years ago. A Nannolitre I have heard of. But where, when and by whom was the term ‘Nannolepi- doptera’ defined? Let alone the name ‘Aplostommatoptera’ for the Hepialidae. An elementary book like this for the beginner is not the place to introduce new, confusing and certainly controversial taxonomic revision. It is the duty of an Editor, surely, to see that a book is not full of mistakes. Unfortunately in this instance he has failed. The number of spelling errors are so numerous as to be misleading and completely spoil the book. On this count alone it cannot be recommended. Page 11 is a particularly glaring example where we have Tortricidea for Tortrico- idea; Cossidea for Cossidae; geometride for geometrid; Sphingaidea for Sphingoidea; Sphingaidae for Sphingidae. The Descriptions of the Moths gets off to a bad start with Laetheo for Laothoe, correct in the index, which however quotes the Twent Plume moth, this however correctly being Twenty Plume in the text.

Worldwide Butterflies Ltd. SHERBORNE, DORSET. DT9 4QN. Telephone: Yeovil (0935) 4608 ee wey BULLETIN deiceteie EDITORIAL There are some two and a half million fishermen in Great Britain and perhaps an equal number of sportsmen who shoot game of one sort or another. By their sheer numbers they are both afluent and have considerable power as pressure groups in politics and in planning matters. The number of Entomologists, on the other hand, is but a handful, some five thousand at most, and this, it would appear, is the reason we, as collectors of insects, are castigated by the conservation lobby and have such little influence in planning matters including habitat destruction. We are weak in numbers and finance and like so many minority groups can safely be turned upon and ignored. But the ento- mologist has as much right to collect insects as the fisherman has to fish or the sportsman to shoot partridge or deer. It can be argued that both fisherman and sportsman breed and stock their collecting areas. This is indeed so, but then so do entomologists. Long before the first world war insects were being bred and released. The late Sir Winston Churchill was a notable stocker of his garden with reared butterflies. Consider, too, the history of such species as the Map butterfly, the Large copper and the Swallowtail; There is absolutely no doubt that many more of these have been reared and released than have ever been caught in the whole history of collecting. It should be made quite clear that the entomologist has as much right to collect as the fisherman to fish, or the sportsman to shoot. The Naturalists’ trust that lets the shooting rights in reserves for money really does not have a leg to stand on when it then forbids the collecting of insects. More and more evidence is accumulating that points to far greater destruction and disturbance of wildlife by the large parties that, non-collecting, now tramp around nature reserves. Two or three careful and responsible collectors, as most of us indeed are, remove less by capture from a given environment than fifty or more people, observing and photographing as they go, trample underfoot. Although it is obvious that the situation as a whole is very complex and there must be many variable and interrelating factors involved, people who object to collecting should, in many instances, first “cast out the stye in their own eye”. How many nature-lovers bringing their dogs on field trips, object to the sight of a butterfly net and very conveniently “‘forget’’ that their dog is largely fed on the meat of whales, now considered to be being slaughtered beyond safe survival point—there was indeed a protest march held in London last December in support of a campaign to stop this killing. 54 MAY, 1977 Entomologists should be able to collect with confidence and without hindrance. They should also respect the country code and use the right to collect with discretion. Unnecessary killing must not be indulged in and there are of course a few instances—such as the present status of the Large blue—where no specimens should for the present be taken. COCCINELLA My dear, have you heard of that nice Lady Bird Who yet is no Lady, and yet is no bird? Who once, if not now, in the land of the plough, Was called by the clod-hoppers there, Lady Sow, Yet still is no lady, and still is no sow? Who some Frenchman (at least, unless custom has ceased) Call béte a Vierge, or the good Virgin’s Beast? Though never the Virgin, and never her beast? Whilst others avow, with a frenchified bow, It is bonne vache a Dieu, the Creator’s good cow, Though never a vache—I mean, never a cow? Jennet Humphreys SPRING COLLECTING IN CALIFORNIAN CHAPARRAL During early May, 1975, I was lucky enough to do some collecting in the Los Padres national forest, some 55 miles north-west of Los Angeles. Much of this region is accessible only by rough track, and I was very fortunate in finding a fellow entomologist with a sturdy car who offered to take me. The climate of southern California is of a Mediterranean type with warm to hot very dry summers, with abundant sunshine and warm, moderately wet winters. Whereas in Europe the typical vegetation of this climatic type is drought resistant carobs, olives, cistus, heaths and lavender, etc., that of California up to 4,500 ft is chaparral which, though resembling Mediterranean maquis, contains many species which are fire-resistant and a rich diversity of woody shrubs such as Quercus spp (oaks), Cercocarpus spp. (mountain mahogany), Ceanothus spp. and Yucca spp. These support a great many species of butterflies, particu- larly hairstreaks. In addition to the chaparral vegetation of the lower foothills, a considerable part of the Los Padres national forest is, above 5,000 ft, covered in pine forest (mostly Pinus ponderosa Dougl.) mixed with oak. My collecting trip was in early May, at the beginning of the season, and was consequently too early for the majority of Lepidopteran species. Nevertheless, twelve species were taken. The most spectacular of these was the Pale swallowtail (Papilio eurymedon Lucas). This magnificent species I took at fairly low elevation alongside a small road which was bordered by a steep shaded bank covered with a variety of flowering AES BULLETIN, Vol. 36 55 plants. It flew along a well-defined beat, occasionally alighting on mud to drink. Three species of Pierid were taken, the most common being the Sara orange-tip, (Anthocharis sara sara Lucas). The wing tips of this diminu- tive orange-tip are of a much more reddish hue than those of the European species, A. cardamines Linn. and both sexes have orange tips. One specimen of the related Grinnell’s marble (Anthocharis lanceolata australis Grinnell) was taken. This species is apparently rather scarce and lacks the orange wing tips of A. sara. The other species of pierid present was the Californian white (Pieris sisymbryii sisymbrii Boisduval) which preferred the tops of the hills rather than the sides. All the Pierids were found amongst hills covered with yellow flowering Compositae, so abundant at this time of year. California is not a good area for the Satyridae, and only two species are found, one of which is abundant; Coenonympha california california Westwood. Some authorities refer to this species as a subspecies of C. tullia Mueller, and compared with European specimens is is considerably paler, presenting a very faded appearance. This common butterfly was taken in dry grassland or oak woodland. One representative of the family Nemeobiidae was taken, Apodemia mormo virgulti Behr. This polytypic species occurs throughout the arid regions of the Western USA and northern Mexico, though this particular subspecies is restricted to the chaparral of Southern California. Four species of the family Lycaenidae were taken. The tiny Western elfin (Incisalia augustinus irioides Boisduval) is an overall dull reddish brown butterfly common in early spring. It has an unusual foodplant, which is a vinelike parasite (Cuscuta sp.). Another hairstreak taken was Callophrys dumentorum dumentorum Boisduval, the Bramble hairstreak, a Close relative of the European green hairstreak (C. rubi Linn.) which in its brown upperside and green underside, it greatly resembles. The specimen taken was rather worn, as this is a very early flying species and is normally on the wing from February to April. Two ‘blues’ were taken, Plebejus icarioides evius Boisduval and Glaucopsyche piasus piasus Boisduval, and only males were seen. The latter species is decidedly uncommon and is a montane species of Western America. The one remaining butterfly taken was a skipper, Erynnis propertius propertius Scudder and Burgess, which resembles a very large Dingy skipper (E. tages Linn.). It is a widespread species in California. With regard to Lepidoptera other than butterflies, one moth was captured, a day-flying Sphingid, Proserpinus juanita Stkr. Seitz (1908-1928) does not mention this species as occurring in California. R. G. Payne (3856) REFERENCES EMMEL, T. C. and EmMMEL, J. F., (1973). Butterflies of Southern California.

Stuttgart. 56 MAY, 1977 A NEW SPECIES OF Polyura (Lep: Charaxinae) FROM THE NEW HEBRIDES WITH SOME NOTES ON ALLIED SPECIES IN THE AUSTRALIAN REGION Butterflies have received more attention than any other insect group so it is hardly surprising that the many new species described annually are often closely similar to their known allies. The discovery of such a large and distinctive species as that here described is therefore a rare event. Polyura sacco sp.nov. (Fig. 1) Male forewing length (base to tip) of holotype 39mm (variation in type series 39-40mm). Recto ground dark brown-black; dense greenish basal scaling. Inter- nervular white fringing. Outer forewing margin distinctly concave from veins R: to Cu, where it projects sharply. Two elongated quadrate primrose spots, basally concave, in areas R; and M:. Separate and basad two further spots in areas M: and M:, the former adjoining but not entering discal cell. These form an out- curving broken chain with a primrose band crossing areas Cu:, Cu, and 2A; this band expanding towards the inner margin. Distally a submarginal series of seven primrose spots (the last divided) from areas R; to Cu., following outer marginal curvature. Hindwing crossed by a distally straight-edged median primrose band, tapering to a point in area Cu;. From area M:; to just before anal angle, outer edge of this band interrupted by a fragmented bifid area of greenish scaling. Complete submarginal series of primrose lunules, darkly divided from a recti- linear marginal series of rich orange colour. Strongly tailed at veins M; and Cuz, the former more than one-third longer. Verso pattern broadly as recto but more ornate. Ground a rich red-brown, darker towards forewing tornus. Primrose spots and bands somewhat paler. All pale areas, other than submarginal spots, broadly margined with black basad. Submarginal forewing spots inwardly margined by light brown lunules and a silver-blue dark-edged line. Traces of this silver also on inner edge of the roughly triangular dark-margined spot at end of discal cell (hereafter referred to as the ‘critical spot’), also around the dark bar crossing the cell. A silvery, dark-margined median band on the hindwing duplicated basally by a narrower stripe—tawny area separating these stands out sharply. Submarginal hindwing primrose spots reduced to small cusps. Between these and the orange marginal chain a further series of pale blue, black-centered, ocelli-like lunules. Bounding the median band distally a series of large reniform spots, inwardly blue-margined. These are deep maroon except those in areas R; and M; which are pale orange (a feature of allied Polyura species). Male genitalia (Fig. 2) compared with the nearest mainland ally P. sempronius F. “male genitalia of sacco differ from those of sempronius in being, on the whole, smaller in size, with the aedeagus slightly shorter (9.2mm in sacco com- pared to 9.5mm in sempronius) and the valves also slightly shorter and narrower (cf. 2 A and B), with the apical hook of the valves smaller and the costa shorter, and the saccus smaller, and the two anterior projections of the juxta shorter”. (Rydon 1976). Female forewing length (base to tip) of allotype 49mm (variation in type series 45mm-49mm). Wing pattern on both surfaces corresponding closely with male; primrose markings rather more extended and outer greenish dusting of hindwing median band heavier. Female genitalia not examined. Additional notes on superficial anatomy (both sexes). Antennae black, tipped with reddish orange. Palps and legs above black, below creamy. Four cream spots on head. Dorsal body surface clothed with greenish- brown hair-like setae. AES BULLETIN, Vol. 36 57 Fig. 1 Polyura sacco sp. nov. Tanna Island, New Hebrides.

The New Hebrides (a Condominium administered jointly by Great Britain and France (see Fig. 3) form an incomplete double chain of approximately eighty islands stretching NW to SE for four hundred and fifty miles. Tanna Island is one of the most southerly and some thirty two miles long and fifteen across. It is the most fertile island in the group, well wooded and watered. Highest point Mt. Merrin (3420 ft). The mountain ranges include one of the world’s most acces- sible constantly active volcanoes, Mt. Yasur. Rainfall is heavy; dry season lasts from 2-4 months. (Pacific Islands Yearbook 1972). “‘P. sacco is found in an area extending from five miles south to ten miles north of the district headquarters station of Isangel/Lenakel and for about a mile inland from the coast. As much of the south of Tanna is densely forested, however, and as collecting is confined to the few and primitive A.H.B.Rydon del.

AES BULLETIN, Vol. 36 59 earth ‘roads’, it is probable that the butterfly occurs over a much wider area. The fact that it has hitherto escaped detection in a fairly well collected locality suggests that it may eventually be found to occur on the neighbouring islands such as Erromango”’ (Burgess 1975-6). Field Notes. “The first specimen (a female} was taken by Father A. Sacco of the Roman Catholic Mission on Tanna and the species is named in his honour. By an odd coincidence I met him on the evening of the day on which I saw a male in the forest some five miles away from Isangel and he then described an exactly similar butterfly that he had seen for the first time in the garden of the Agricultural Officer’s house that morning! The next day he brought me the first of the females so far taken. This and subsequent females were taken feeding on the sap oozing from the clump of young eucalyptus trees in Lenakel, the centre of the district headquarters, where the Royal Society expedition team collected intensively for about 3 weeks in 1972! They usually seem to sit head-down on the bark about five feet from the ground. Both Father Sacco and myself have seen the male on different occasions flying high along forest tracks some five miles north and south of the station, in an area about a hundred feet above sea level. All the specimens so far captured (up till January 1976 only females and subsequently mainly males) have been taken while feeding on the exudation from wounded trees particularly mandarin orange which occurs in a semi-wild state throughout the area, but also on eucalyptus species and once on bamboo. On the last occasion the attraction was apparently the ‘spittle’ exuded by a dense colony of aphids or sucking insects rather than the sap of the bamboo itself. Normally these exuda- tions seem to be most effective when fermenting, the butterflies becoming visibly drunk after feeding for some time; but none of the traditional baits for Charaxinae, alcoholic or otherwise, have so far had any success in attracting them. At other times sacco seems to be very shy and retiring and has only been seen on the wing on two or three occasions. It has the typically powerful flight of the Charaxinae, and both Father Sacco and I were struck by the superficial resemblance of the upper surface to Papilio machaon 1. when we first saw it. The foodplant is possibly a local species of Poinciana a tree endemic to Tanna known locally as ‘mahogany’, but all attemps to induce captive females to lay on this and other Leguminous tree species have so far failed.’’ (Burgess 1975-6). The relation of sacco to other Autralasian Polyura. The latest publication to list the known species of Polyura (Smart 1975) includes seven species occuring in the Australian region, viz. species generalised distribution athamas Drury Timor & Wetar gamma Lathy (aristophanes Fruhstorfer) New Caledonia 60 MAY, 1977 caphontis Hewitson Fiji epigenes Godman & Salvin Aola & Guadalcanal clitarchus Hewitson New Caledonia & Loyalty Is. jupiter Butler New Guinea—Solomons pyrrhus Linnaeus Moluccas All these species were known to Fruhstorfer (1927) and all are figured by D’Abrera (1971). The latter, however, regrettably transposed the figures of epigenes and gamma. On page 246 the specimen shown as epigenes & is gamma ov: that shown as epigenes Q is epigenes & and that shown as gamma & is epigenes Q. P. athamas is primarily an Oriental butterfly and may be disregarded for the moment, leaving six species to which should be added sacco and sempronius Fabricius; the latter found on the Australian mainland and also Lord Howe Island. Up till now sempronius has been treated by all authors as a race of pyrrhus from which it differs in the extended cream basal area and body colour, unequal tail length, more strongly orange hindwing margins and other details. gamma, caphontis, epigenes and sacco are so isolated geographically and unusal in wing pattern that they merit separate consideration. The remaining four species—pyrrhus, jupiter, sempronius and clitarchus form a reasonably homogeneous ‘pyrrhus-group . The probable development of these Australasian Polyura (and indeed Charaxinae generally) will be outlined in a forthcoming article, but my preliminary researches leave me to speculate (and this is merely specula- tion) as follows. Zeuner (1943) suggested Sundaland (the Pleistocene land-mass com- prising the Malay Peninsula, Sumatra, Borneo, Palawan and Java) as the developmental site for the Indo-Australian ‘Birdwings’ (Troides, Trogonoptera and Ornithoptera (Papilionidae). The very similar distribu- tion of present-day Polyura species raises the possibility that we might look for their origins also in this area. The discovery of sacco provides a clue to the way in which dispersal from Sundaland may have taken place. sacco possesses certain features that relate most strongly to Oriental Polyura species—for example unequal tail length, extended red-brown antennal tip, relatively unspecialised wing pattern with clearly defined bands and spots, orange hindwing margins and, most significantly the shape of the inner edge of the ‘critical spot’ in the discal cell on the underside of the forewing. In the set insect this edge is almost vertical, turning out very little and almost parallel with the basal side of the hindwing median band. The continuity of these features is particularly well demonstrated in the female (fig. 1). This formation is common to all Oriental Polyura except dehaani Doubleday and delphis Doubleday, both of which have a more specialised wing pattern. In contrast the ‘critical spot’ in all members of the pyrrhus-group turns out sharply.

While sacco is therefore, in my view, the most ancient form, there is sufficient justification for regarding all the remote Polyura viz. gamma, epigenes, caphontis and sacco—as the product of an early dispersal from Sundaland, through New Guinea to the Solomons and beyond. The evidence for a much closer geographic relation between these areas was 62 MAY, 1977 provided by Wegener (1924). With the break-up and general south- eastern drift of land masses in this area, coupled with intense volcanic activity submerging much of the island chains, these four species have become isolated. The development of the pyrrhus-group, from an ancestral form which I will refer to as U-pyrrhus, has taken place more recently. sempronius and clitarchus represent an early stage in the separation of this group. The presence of the latter on New Caledonia together with gamma is coincidental—they are widely separated in evolutionary time. The splitting of U-pyrrhus into pyrrhus and jupiter is certainly much more recent. Separation of races of these two species in the Banda Sea area proves difficult. It is possible that these forms represent a transitional stage in the development of pyrrhus and jupiter from the hypothetical ancestral form. Acknowledgements I wish to express my thanks to J. A.

SOME OBSERVATIONS MADE DURING A PHENOMENAL SUMMER The summer of 1976, which followed a dry winter and a previous summer which had been unusual for its lack of rain and its high temper- atures goes down in the records as unprecedented within living memory. Its effect on the flora and fauna of the countryside may be long lasting but we have been able to see some immediate results and a few of these are recorded here. As a bee-keeper I observed that the flow of nectar from most plants was greatly reduced and in my area the heaviest crop for the bee-keeper, the Limes, produced nothing, the blossoms opening AES BULLETIN, Vol. 36 63 and withering almost immediately. Despite the ability to forage every day for months, the bees have stored only half the honey of last summer. The effect of the drought on butterflies has been most noticeable. Numbers have increased by large factors, particularly in the case of double brooded species. In July I noted that a nettle-bed which stretched along the side of a field had been completely defoliated by larvae of the small tortoiseshell, Aglaise urticae L. The second brood of the Adonis blue, Lysandra bellargus Rott., emerged at the beginning of August as against mid-August of previous years and most colonies had doubled in numbers. Single brooded species such as the Purple emperor, Apatura iris L., and the White admiral, Limenitis camilla L., were not only more numerous than in previous years but also were observed in an extended range. Emergences were very early and I observed iris laying on the 9th July, already its wings badly torn while camilla was almost over and already larvae had hatched. The eggs were spattered widely in its haunts and I found three on one leaf. Predators appear to have increased com- mensurately as many eggs had been sucked by bugs or lacewing larvae and spiders were everywhere so that next year’s crop may not be as heavy as would appear from this year’s fecundity. Wood whites, Leptidea sinapis L., appeared along roadsides and were obviously spreading their range in early May. I have never seen the comma, Polygonia c-album L., so common and several patrolled my garden in early July. However the dryness changed the habits of many species. The Meadow brown, Maniola jurtina L., suddenly became a woodland butter- fly, forsaking the fields to find the shade and moisture offered by wood- land rides. Butterflies congregated at any source of moisture has been observed most often in South Europe and in the tropics. They would even alight on arms to sip sweat and many seemed exhausted by the conditions. L. D. Young observed A. iris males crawling over a rubbish dump trying to find moisture and it became quite easy to catch many species in the hand as they became lethargic and absorbed in the search for water. Dark green fritillaries, Mesoacidalia aglaia L., on the North Downs could be picked off the flower heads, a contrast to their usual rapid dashing about the slopes. The Chalkhill blue, Lysandra coridon Poda, was out well before the end of June in some localities and I saw hundreds near Winchester on the 18th of July of both sexes. However the downlands were everywhere very parched and even the deep-rooted Horseshoe vetch, Hippocrepis comosa L.. was shrivelled and in bad shape. Fortunately the butterfly normally lays its eggs on grasses near the foodplant and will not be needing it until next spring when it should have recovered. One matter of interest was that all the second brood imagines of the Small Copper, Lycaena phlaeas L., which I saw were of the heat form which is norm- ally found in southern Europe, f. eleus Fab., being heavily suffused with dark scaling and having more pronounced tails than the typical form. 64 MAY, 1977 Several I took looked exactly like specimens I had taken in Corsica in July some years previously. Holly blues, Celastrina argiolus L., produced a second brood early in July and as the Ivy was not yet in bud one wonders what they chose as a foodplant. I have seen them laying on the flowers of Cornus sp., Dogwood, and this July I observed a female con- tinually crawling about over the buds and flower heads of Bramble. Rubus sp., but could find no eggs. Moths also seemed more numerous in some species while others, notably the hawkmoths, appeared to be about average. What was sur- prising however was the early date of emergence of species feeding up this year. On the Ist July I observed a Red underwing Catocala nupta L.., on the wall of my house, a species which I do not usually expect to see until near the end of August. On the 2nd August I counted five specimens perched under the eaves. Dr. Paul Boswell informed me that he had seen a Herald moth, Scoliopteryx libatrix L., also at the begin- ning of July: a bit early to herald the coming of winter! Several trees locally were completely defoliated by the Bufftip moth, Phalera bucephala L., a species which had been much less common in recent years and everywhere on the Ragwort were the larvae of the Cinnabar moth, Tyria jacobacae L. It is certain that many species will have pro- duced total or partial second broods this year and perhaps some, like the Small copper, will produce a third. What has also been noticed is the build-up in two migrant species of butterfly, the Red admiral, Vanessa atalanta L., and the Painted lady. V. cardui L. which first appeared early in May and produced a strong brood in August. The absentee, as far as my observations are concerned, was the Clouded yellow, Colias crocea Geoff., but my trip to France in 1975 had convinced me that we should not see another ‘Colias’ year despite the ideal conditions. That great arable barrier on the continent would prevent any massive build up of previous peak years. Even at this late stage I hope that we may find some arriving here via the south of France and Ireland and the west country. What I feel this year has proved is that given the right habitat and good weather, our butterfly and other insect populations can thrive. Several bad years and the decline in suitable habitat has reduced our relict insect fauna and just two good seasons have worked a change. If only suitable habitat could be increased to go with the change in weather, there would be no fear for the future. Man can control the latter but not the former and it is up to us individually and as a Society to try to bring about some improvement in the retention of suitable places for our insects to con- tinue to live. Knocking collectors seems to have become even a national pastime from letters and items appearing in our national press but there is no evidence of any species having been made extinct by collecting. although some species in restricted areas must be given protection today. Amateur entomologists are the persons most concerned at any diminu- tion of our native insect fauna and without their enthusiasm the little AES BULLETIN, Vol. 36 65 progress that has been made might not have taken place. If the work is to continue then entomologists, whether collectors or not, should not be prevented from carrying a net with them when visiting suitable areas. whether the land be private or public as long as the public has general access to that land. It is not possible to study flying insects without netting at least the occasional one. In preventing the depradations of a possible ‘demon’ collector, the legitimate activities of others are hindered and the future training ground for entomologists of the future could cease to exist. If all keep to the ‘Code of Collecting Insects’, the man with the net should not have to face being accosted, sometimes beliger- ently, and threatened with possible legal action. Some thought Lady Granville mad for collecting butterflies—today there are those who are prepared to consider it criminal. Let us hope that we can retain some common sense and deal effectively with the black sheep without killing the whole flock. P. W. Cribb (2270) OBSERVATIONS ON THE EARLY HIBERNATING BEHAVIOUR OF THE PEACOCK It is noticeable that some species of butterflies that pass the winter in the adult state, appear to go into hibernation at a much earlier date than one would expect, often when there is still plenty of available food and the weather is still suitable for flight. This behaviour particularly applies to Inachis io L. (The Peacock), Gonepteryx rhamni L. (The Brimstone) and Nymphalis polychloros Loft. (The Large tortoiseshell) whereas Aglais urticae L. (The Small tortoiseshell) usually carries on into the autumn until the weather becomes too bad for flight and feeding. This also applies to a lesser extent to Polygonia c-album L. (The Comma). The following notes and table apply to /nachis io the records being mostly from my garden at Cheriton where ample food is supplied by several varieties of Buddleia, Valerian etc. : Taking the last three years including 1974 (a bad summer) it can be seen from the table that the summer flight comes to an abrupt end towards the end of August, with only one or two stragglers in September after an interval from the last day of abundance in August.

After that, as can be seen from the table, there is an interval of any- thing from 14 to 23 days before one or two odd specimens are usually seen in September. One would imagine a gradual tailing off rather than an abrupt end to relative abundance. Although only the last three years are given as examples my past records more or less show the same phenomenon, and it is difficult to see the reason for it. Owing to its rarity, I have not been able to make suitable observation on N. polychloros but I think it is generally understood that this species has an even shorter summer flight, going into hibernation (or aestivation) not long after it emerges in July. The only conclusion I can come to is that by the end of August the butterflies have reached the final stage of ‘fat-body’ development to with- stand the winter and there is little point in continued flight. It is interesting to note, however, the near relationship between io and poly- chloros, and similarity in behaviour. The unusual summer of 1976 has, however, brought to notice one interesting point and that is the early disappearance this year of A. urticae, in contrast to its usual habit of autumn flight. After what must have been record abundance during the summer, only 7 were seen after September 4th, the last sighting being on September 28th and not one visit to Sedum spectabile H. was observed. In contrast the more vulnerable (non-hibernating?) Vanessa atalanta L. (Red admiral) has been seen this year on almost everyday during September and October, the last two seen feeding from Choisya ternata on October 16th. B. R. Stallwood (1547) A USEFUL AID TOWARDS BREEDING LARVAE IN CAPTIVITY Over the years we have spent breeding lepidoptera we consider that we have found an answer to the problem of keeping specially kept plant material in a suitable condition in rearing cages for larvae. The most frequently mentioned method referred to in entomological literature is the use of a glass jar with a plug of cotton wool at the neck around the stems of the plant material to stop wandering larvae (often seeking moisture) from crawling down the stems and subsequently drowning. This method is certainly quite satisfactory for larger twigs and bulky material; but does have the drawback of involving a length of time in order to change old material for fresh. In recent years, however, various proprietory brands of a foam AES BULLETIN, Vol. 36 67 material has been available on sale through florists and garden centres for use by the flower arranging fraternity. This foam material absorbs water very quickly and its use towards keeping plant material fresh has the following advantages over the old method: — 1. It is easily penetrated by even soft plant stems. 2. It is particularly useful for holding the small plant stems required when rearing small larvae in their first and second instars. 3. The proces of changing food material is far shorter (perhaps par- ticularly beneficial to those who have limited time at their disposal! ) 4. It provides a “dry” source of water supply without the attendant risk of larvae drowning, yet allows larvae to suck water from it. 5. It is extremely useful when rearing species which require an atmos- phere of high humidity as this material acts as a source of water vapour in a sealed container. Attacus atlas larvae we find flourish with the use of this material in a container placed in an airing cup- board, otherwise too low in humidity. 6. This material is best placed on a metal or plastic disc or placed in a sealed polythene bag to avoid undue evaporation. 7. It is inexpensive to purchase. N. F. Gossling (5169), C. Orpin (5736) AN INVESTIGATION INTO THE ULTRA-VIOLET PATTERNS OF BRITISH BUTTERFLIES Inspiration for this project was provided by an article that appeared in ‘ANIMALS’ magazine (now ‘WILDLIFE’) in January, 1974. The opportunity for the project to be compiled was presented by the Biology A-level syllabus, which allows candidates to submit a project as part of the examination. By definition, ultra-violet patterning in butterflies is invisible to the human eye. However, this problem is easily resolved as ordinary film emulsions are sensitive to ultra-violet light. There are two basic types of colouration present in butterflies: pig- mental and structural. Pigmental colours are produced, as the name suggests, by the presence of coloured substances in the scales of the butterfly’s wing. These substances are usually contained in pigment granules in the scales. Structural colours are produced by the con- structive interference of light being scattered off the ridges of mullti- lameller structures present on the scales. Pigmental colouration is responsible for most of the colours present in butterflies—the white of the “‘Whites’’, and the other browns, yellows and reds that occur. Structural colouration is responsible for all the metallic colours of butterflies, such as the blues of the ““Blues’’, Morphos and Vanessids. Most of the instances of ultra-violet colouration in butter- flies so far reported have been structurally produced. “yyy yyy ol YH yy Yi QD SS RAS Fig. A.

The Purple Hairstreak (Quercusia quercus L.), typical of a species exhibiting structural ultra-violet patterning where structural patterning in the blue end of the visible spectrum is present. The major part of the project was the compilation of an almost com- plete survey of the British Butterflies, to determine just which species exhibited any ultra-violet colouration. The specimens were loaned by the AES BULLETIN, Vol. 36 69 natural history section of the Tunbridge Wells Museum, for which thanks are given. The conditions for the photography in this survey were standardised from preliminary experiments with film and exposures. The source of ultra-violet light was a 125 watt mercury-vapour discharge lamp. The film used was entirely Kodak Plux-X (125 ASA), and the exposure details were: 30 seconds at f.8. A deep-violet and ultra-violet filter was also used to minimise the amount of stray light entering the camera. Almost all the British species were photographed. Each photograph contained an upperside view of both sexes and an underside view of the male only. In a few cases of special interest an underside view of the female was also included. The results of the survey were on the whole rather predictable, but some individual cases proved to be most interesting. The results can best be summarised by a few brief comments about each family. Satyridae. This family shows very predictable patterning in ultra-violet light, with all the light areas of the wings and the small metallic spots showing up clearly. Nymphalidae. All the species in this family are basically non-ultra- violet reflecting, appearing to be very dark. Only the silver markings of the Fritillaries and the structural blues of this family show up clearly. A marked example of this is the Purple emperor (Apatura iris L.), whose irridescent purple markings in the male show up brilliantly. Lycaenidae. The Blues continue to show that structural colouration in the visible blue range are also prominent in ultra-violet light, as do the Hairstreaks. (Fig. B). The Coppers, however, present a strange anomaly. The structural colouration of the Coppers occurs at the red end of the visible spectrum. Thus, it might be reasonable to expect them not to show any ultra-violet patterns. The Small Copper (Lycaena phlaeas L.) complies with this suggestion, but the Large copper (Lycaena dispar Haw.) (Fig. A). exhibits marked ultra-violet patterning It is quite unexpected that structural colouration in two distinct parts of the spectrum should be present in the same species. Pieridae. The Whites are the only other family which requires any sub- stantial comment, the Papilionidae and others being entirely predictable. The Whites are immediately worthy of comment because they appear black under ultra-violet light. As opposed to the other white pigments present in other families (the flavones), the white ureates of the Pieridae absorb ultra-violet light, hence appearing black. However, there appear to be various degrees of absorption and reflection from the pigmental colours of the Whites. Some work done in Japan claims that the common Whites do show pigmental colouration in ultra-violet light, although only slight evidence was found to support this view.

The Brimstone (Gonepteryx rhamni L.) was the first case of ultra- violet colouration to be recorded, and has since become the most famous. The original observation of the phenomenon was made by the Russian entomologist Yuri P. Nekrutenko. He also showed that other members of the genus Gonepteryx exhibit similar ultra-violet patterning. The coloura- tion is of the structural type, and is limited to the upperside of the males forewings. The female is usually quoted as not exhibiting any ultra- violet colouration, however this investigation would suggest otherwise. The female appears to exhibit ultra-violet colouration on the underside (see Fig. C), but it is uncertain as to whether this is a structural or pigmental effect. This investigation also revealed that the ultra-violet colouration of the male is not confined to the ultra-violet region of the spectrum. The evidence for this first arose from a photograph of a male taken in violet light. The photograph showed quite clearly the same pattern as appears on the wings under ultra-violet conditions. Further, visible proof of this was obtained when the specimen was examined under the intense violet light of a mercury-vapour lamp, when a faint metallic-violet sheen could be seen across the male’s forewings. The fact that these ultra-violet patterns exist implies that they must serve some purpose. In the majority of cases the patterning is an expres- sion of sexual dimorphism, and this would indicate that they are used for discrimination between the sexes in any particular species. Nothing can be claimed as yet in the direction of inter-species communication, as not enough is known about which species can or cannot detect ultra- violet light, although some have definitely been shown not to detect it. The significance of these patterns towards other classes of animals and insects has not been investigated, but work on their significance towards insect parasites of butterflies might be rewarding. This project has barely managed to scratch the surface of a very large subject. There is still plenty of work left to be done on the behavioural significance of these ultra-violet patterns, and the prospect of being able to carry out this work is still very appealing to me. Meanwhile, I would be very glad to hear from anyone who has any thoughts on the subject. Robert Sinclair (5415J) 1976—THE YEAR OF THE MIGRANTS? The Summer of 1975 in Torbay was longer and hotter than usual, never seeming to end and causing an acute water shortage. Insects thrived in the heat and I noticed double broods of some species of moths. As usual, the winter here was quite mild and not too wet and we never really recovered from that beautiful summer. I remember com- menting that we would never have such summer for probably many years. I was so wrong! 72 MAY, 1977 1976 brought even a longer hotter summer in Devon, resulting in such havoc with water supplies and vegetation, that parts of the County were encumbered with stand-pipes in the streets. I was able to search for larvae which were normally inaccessible on marsh land since this had dried up in the heat. From early April until late September, the land was parched beyond recognition of our normal lush green fields and trees. I found larval food supplies to be of poor quality and short lived, even when stood in that scarce liquid—water. With the family washing virtually in the same basin of water and bathing in a minute drop in the bath, I felt rather guilty filling jars with water for foliage on which caterpillars were to feed. On most nights the lamp posts and pavements were littered with resting moths, and hundreds of Heart and Dart (Agrotis exclamationis L.) were forming snow-like storms around the lamps. Night after night I left my moth trap off because of “‘infestation’’ by this species. Indeed, that may sound exaggerated, but from one nights collecting, I released 307 Heart and Dart moths the following day many miles away from my area. This then sets the scene in Torbay, and in such heat and weather, who wanted to go abroad in search of the sun. No doubt, many people did and regretted doing so. I was hopeful that there would be some moths and butterflies flying abroad to England, enticed by the lasting warmth of our summer. Every patch of Buddleia, Valerian and Sedum was examined, and I was finally rewarded by watching a Humming-bird hawk (Macroglossum stellatarum L.) feeding on Buddleia at Exeter on 3rd August, 1976. This first sighting seemed to send this little Hawk into my path and in 1976 I recorded the following sightings: — 1. On 3rd August, as mentioned above. 2. On 7th August, a personal sighting feeding on Valerian at St. Mary- church, Torquay. 3. On 6th September, caught whilst resting on a wall at Kennack Sands, Cornwall by a young boy who brought it to me alive. 4. On 17th September, a personal sighting feeding on sedum at Cowley Wood Conservation Centre, Parracombe, North Devon. 5. On 2nd October, a personal sighting, feeding on a group of garden flowers at Dawlish. 6. On 8th October, found inside a chemists shop at St. Budeaux, Plymouth and brought to me alive. 7. On 9th October, a personal sighting on Buddleia at St. Marychurch, Torquay. 8. On 20th October, a personal sighting, feeding on Buddleia at Hele, Torquay. Local newspapers at Plymouth and Torbay reported the usual sight- ings of “‘Humming-birds’”’ by members of the public. The reports were AES BULLETIN, Vol. 36 73 answered as one would expect explaining about this attractive little Hawk moth. Being basically a breeder, I found all of my time taken up by attending to hundreds of larvae of various species and I had little time for the contents of my moth trap, apart from selecting those females from which I could obtain eggs. However, on 24th August, 1976, I lent the trap to my neighbour—not to catch moths, but to enable him to see in the dark whilst doing some carpentry in his garden at night. When I retrieved the trap I was informed of a “‘huge’’ moth that had been flying around it. His assistant was so frightened that he ran inside the house until it had gone. Disappointed that I had not caught the moth. I lit the trap again in my own garden and immediately heard a gasp from my wife who was pointing to a beautiful male Convolvulus hawk (Agrius convolvuli L.) resting on the garden wall looking very tired and inactive. My good turn to my neighbour was certainly well rewarded for me. On 22nd September, 1976, a garage owner friend brought to me a Spare part box and told me to cautiously open it as I may be interested in its contents. Inside yet an even bigger male A. convolvuli. It had been found resting on one of his cars on the forecourt of his garage. I answered the doorbell on 25th September, 1976 to find a young boy holding out a Smiths crisp bag! ! “I found it on the pavement at Babba- combe and brought it straight to you. It wasn’t there this morning’, he joyfully said. Yes, another Convolvulus hawk only this time a very battered female. Pieces of wing and a cloud of scales were inside the bag. I took her out and she immediately began to fly. Once captured from the curtains she was put in one my breeding cages 20” high by 15” x 12” with some Bindweed (Calystegia sepium), Her activity was incred- ible for a night flying moth at 4.30 pm. Nothing happened that night but on the night of the 25th September, she laid 95 eggs and then died on 26th. The eggs were placed in a 2” x 14” plastic box. Their subsequent history is described in the following article. It also occurred to me that this egg laying Convolvulus hawk must have flown by day as it could not have possibly remained where it was until 4.00 pm. without being trodden on or noticed by other people. The boy also stated that it was not there when he went to school. Had he missed it I’m sure one of the other boys would have noticed it on the pavement. On 30th September, 1976, and in pouring rain at that, I found another female Convolvulus resting on a gate-post at Watcombe, Torquay. On 2nd October, 1976, I was given my last Convolulus moth which again was a female having been found on the front door of a house at Dawlish, Devon. Although both these females were put in the same con- ditions as the egg laying female, no eggs were obtained. 74. MAY, 1977 I wonder how many more of this species flew into Torbay in 1976 when I alone had five. There are indications. For instance there was a newspaper report of “_Humming-birds” and this was answered by Mr. A. F. Baker of Deancombe, Buckfastleigh stating that such sightings could also be Convolvulus hawks as he had seen three of these on the same evening at the same time feeding on his Sweet tobacco plants in early September. I spoke to Mr. Baker by tele- phone and he assured me of his facts and was somewhat disappointed that they had not returned at all since that evening. 3 Ken Bibbings (5712) SUCCESSFUL REARING OF CONVOLVULUS HAWKMOTH As mentioned in the previous article, 95 eggs were laid for me by a Convolvulus Hawkmoth (Agrius convolvuli L.) on the night of September 25th, 1976, the moth having been found at Babbacombe, Devon. I regularly examined the 95 eggs which I considered to be quite small for such a large moth. I was a bit surprised that they had not all collapsed though I noticed that a few had. After the fifth day I saw the tell-tale signs of eggs about to hatch and some Bindweed was put in a Blue Band margarine con- tainer together with the open box of eggs, and they were kept at normal room temperature which was 65°F. As a point of interest, only two eggs were deposited on the sepium by the female. The rest were on the wood supports and the netting of the cage. Seven days after being laid, 76 hatched on 2nd October. The remainder collapsed. The hot Summer had baked the Convolulus arvensis in my arear, and there was a little C. sepium and C. silvatica though this was beginning to turn yellow. I was anxious to find a vast food supply to feed so many so late in the year. I hurriedly planted seeds and forced them along—a futile attempt I found later as this supply was not enough for half a day for one fully grown larva. I tried to hurry the larvae along in a temperature of 80°F. only to lose two, drowned in the condensation. This idea was promptly abandoned. The larvae grew very quickly on the Bindweed and four days after hatching the first skin change took place on 6th October. and for the first time I noticed one larva without a tail horn. I was determined that if disease struck, I would not lose all, and the larvae were divided into tens and put into plastic gallon ice cream containers, lined on the bottom with kitchen paper towels which absorbed condensation really well. The Bindweed was changed each day WITHOUT FAIL, and on one day I found some arvensis which was placed in the same container as some sepium. The larvae actually seemed to prefer the sepium. Another four days passed and the second skin change took place on 10th October. 715 AES BULLETIN, Vol. 36 YY Yj Softly. awk photographed by Mr. nvolvulus h E Adult Co . Fig 76 MAY, 1977 Two failed this change and died. All but three of the rest were green with paler obliques green stripes along the sides with bright organge spiracles and black horns. The other three were black with one yellow line on each side on their backs from head to tail looking a completely different species. I was delighted with the progress the larvae had made but was now very worried that I would lose all through the lack of food. When strolling along with my Police dog one Sunday morning, I walked into an open Council stores where to my amazement I found a massive supply of very green fesh looking Bindweed amongst stacked lamp posts and paving stones. Seventy two larvae made the third skin change succeacrally on 16th, 17th and 18th October. Having been taught to be cautious, I now split them up into threes in sweet jars and plastic containers. The larvae were most variable in their markings and colours in this instar and at least half of the green ones were now black. During one of the daily food changes, I moved a heavy plant pot of growing Bindweed and put it down straight on top of two larvae with fatal results. I called myself more names than anyone else had ever done. With my food supply still holding its own, the larvae began to consume large quantities each day. The rain that we had needed so urgently had become a nuisance to me having to dry off each individual leaf day after day, and with armfulls of it at a time, this practice was not appreciated by my son and daughter. The final skin change commenced on the 23rd October; which one larva failed to make it properly and was discarded. Three others fed up for a while and then stopped eating and withered and these too were discarded. One larva for some reason unknown to me was two skin changes behind and very small. This one was released to the wild on sepium and soon vanished. I now possessed 65 perfectly healthy larvae and it became necessary to change the food twice a day and I maintained absolute cleanliness twice a day. This was very tedious and it appeared that tending these caterpillars was the only thing I ever did at home after work! It seemed strange to me that all of these larvae displayed no green colour at all now and South reported the more usual form being bright apple green. My larvae were all of the dark form which was basically made up of black, orange, brown and white with five main variations which made them all appear to be from different species at first glance. The largest larvae which were 44 inches long at rest were placed in a 24” x 15” x 12” fish tank a quarter full of peat. On top of this a piece of corrugated P.V.C.was rested on four posts thus holding it two inches above the peat. Bindweed was put on the P.V.C. sheet the corrugations of which conveniently collected the frass away from the food. After a long session of wandering, discarding the final pieces of body waste, 41 larvae were removed from the tank and placed in separate pupating containers which were sweet jars, one third full of new peat. The first AES BULLETIN, Vol. 36 77 a EE EE ee ee aL, Fig. D Group of Convolvulus hawk larvae feeding on Bindweed. (Photograph by Ken Bibbings) group went down on 31st October, 1976, just 29 days after hatching. The remaining 24 larvae were left in the tank to pupate. The others had been removed to prevent overcrowding and badly formed pupae. The last went down on 7th November 1976, all having been extremely healthy. At last I could relax evenings. 78 MAY, 1977 I noticed that the larvae were non-aggressive in any instar, and when fully grown were quite happy to feed three to one leaf often attaching themselves to each others bodies, or walking over each other without the usual flinches to ward off intruders. I let a month pass before disturbing the pupae and found each separate container revealed one perfect and lively pupa. Even the larva without its tail horn was perfect except that its wing cases are pointed. Elated with my first attempt at rearing wild A. convolvuli larvae so late in the year with 41 very large pupae to my credit. I went on to examine the 24 in the fish tank and—DISASTER!! All of them were either deformed or had failed to cast that final skin. The deformities were so bad that all were discarded. They had pupated well away from each other in beautifully smoothed cells. I concluded that possibly the peat held a disease of which I had no idea, and yet the other 41 had wandered on and lived with it for some time. Anyway, I disposed of all my peat and disinfected all pupating containers. My final conclusion is that the temperature fell to 55°F. to my knowledge and it had probably been lower at night during the time that the last 24 were pupating. The others never suffered this temperature drop at all. So it is possible that through me being too complacent at a crucial time, that it was my fault that these poor final few have had to perish. However, I derived enormous pleasure from rearing these Convolvulus hawk larvae encouraged by the fact that it is rarely achieved from a wild caught female in this Country. Ken Bibbings (5712) CONSERVATION AND SCOUTING In 1976 the Second Bexley Scout Group studied for the Cub Scout World Conservation Badge (introduced in World Conservation Year) and the Scout Conservator Badge. As it turned out the most popular of the many natural history and environmental projects was a ““mothing evening”. After half an hour of theory (including safety rules) the boys observed the effects of a mercury vapour lamp set up in my garden. Forty-four species of macrolepidoptera were identified between 10 p.m. and mid- night. All the species were common but they were of course mostly new to the boys who were particularly attracted to the larger and more brightly coloured moths such as The Large yellow underwing (Noctua pronuba L.), The Swallow-tailed moth (Ourapteryx sambucaria L.), The Angle shades (Phlogophera meticulosa L.), The Ruby tiger (Phragma- tobia fuliginosa L.), and the Oak hook-tip (Drepana binaria Huin.). Of special interest was The Peppered moth (Biston betularia L.) which appeared in both the light and dark forms. The history of this moth is too well known to repeat here but on this occasion it provided a very useful if elementary illustration of natural selection. AES BULLETIN, Vol. 36 79 The fascination of the m.v. lamp technique was such that the badge examiner (The Assistant District Commissioner for Cub Scouts) who looked in “‘for ten minutes” stayed for two hours. May I suggest that other enthusiasts give demonstrations to youth groups in the cause not only of conservation but in an endeavour to arouse interest in entomology and wild life generally. Care must be taken to ensure that no children are endangered by any equipment used and they should always be accompanied by and under the control of their authorised leaders. It would be as well to make sure that any group which you entertain is covered by its own insurance. If I might mention a side benefit of scouting, I was sugaring along a woodland lane in North Kent in Autumn, 1976, when I was stopped by the warden of the adjoining scout camp who had spotted the scout badge on my anorak. When I explained what I was doing he immediately gave me permission to sugar and use m.v. equipment within the grounds of the extensive scout camp. He generously extended this offer to a local society which I was helping with a wild life survey. Tan Brydon (5881) BOOK REVIEWS THE INSECTS AND PLANTS OF THE ALVER ESTUARY, by David Appleton, Michael Bryant, Richard Dickson and George Else. pp. 154; 4to. Duplicated and published by R. Dickson, n.d. (1977) Price 60p. (By post 89p) This is another of the excellent local lists that is being produced these days and although it extends to include more than just one order of insects the title is a little misleading as in fact only three orders are really covered, the Lepidoptera, Coleoptera and Hymenoptera, in that order, with 21 pages devoted to the plants. The Alver estuary is in Hampshire and adjoins the Solent. We learn from the introduction that it is undoubtedly one of the most important entomological sites in the county, if not the country, and we learn of the utter sterility and callousness of Gosport Council’s treatment of the site which is in great danger, both from greed and vandals (arsonists). This is a timely list which wisely draws attention to the problems facing the site and makes recommendations for its future. Let us hope they be followed. The introductory pages are of further use in that they give us details of how to get permission to collect and a map of the area is included, as well as a summary of the more interesting insects to be found. The lists themselves are primarily of a decade of observation of the area by the various authors, plus gleanings from their friends and col- leagues. It is therefore very much an up-to-date list, well laid out and with comments. The advantage of having a plant list published together with an insect list means that the insects can and have been correlated with the plants they are associated with. 80 MAY, 1977 This is an interesting list and in view of the price, worthy of a place in any entomologists library. It should be made clear that it is a typed and duplicated book and it cannot be too strongly emphasized that both the typing and duplicating have been exceedingly well done. It amazes us that Mr. Dickson has produced it at a price of only 60p. It appals us that H.M. Post Office charge 29p for its postage. At present copies are obtainable from any of the authors, and in particular Richard Dickson, Flagstones, Catisfield, Fareham, Hants (89p post free). Copies will however be available at our next annual exhibition. S.R.G. BIRDWING BUTTERFLIES OF THE WORLD, by Bernard D’Abrera. U.K. edition 1976. pp. 260 including 216 colour plates. Hamlyn Pub- lishing Group (for Country Life Books). Price £35.00. Whatever else this lavishly produced book may be, I dispute the pub- lishers’ claim that is the definitive monograph of the Birdwing Butter- flies. Large, heavy, handsomely bound, complete with an inscribed box holder—it is doubtless pleasing to the eye, but it is also very expensive and offers little to the entomologist seeking a practical reference book on this remarkable group of insects. The focal point of the book consists of Mr. D’Abrera’s own colour photographs (life-size) of set male and female specimens of nearly all 120 species and sub-species of the Ornithoptera, Trogonoptera, and Troides genera which are covered. Interspersed with these are nearly eighty colour photographs (in close-up) of the early stages of nine species reared by the author or his colleague Mr. Richard Carver, mostly in Australia. Some of the latter shots are remarkable—I like in particular a whole- page study of the fully grown larva of Ornithoptera urvilliana on p.89. Grouped at the beginning of the book are a further fourteen colour photo- graphs of typical habitats ranging from Sri Lanka through Malaysia and New Guinea to Queensland. The quality of all these plates is of a very high order, printed as they are on a very heavy coated paper. The text provides little more than verbal decoration to the colour plates. Apart from a brief introduction and a useful bibliography, the book consists solely of the author’s discussion (not description) of each species illustrated; this consists of a highly personal summary of what he thinks the reader wants to know about each species. In the process a certain amout of interesting information about the Birdwings as a whole is buried amongst references to previous authors, anecdotes of personal acquaintances, and descriptions of breeding experiments and various collecting expeditions. Mr. D’Abrera does not attempt to make any overall survey of such vital topics as distribution, taxonomy, life-cycle, conservation, larval food-plants etc. and so his book lacks any overall theme. For all this, it is interesting to glean such information as the fact that Troides prattorum is immune from collectors because of its restric- tion to a single Indonesian island which is used as a prison camp, AES BULLETIN, Vol. 36 81 inhabited by cannibals, and surrounded by shark-infested waters! Incidentally, a historical error has crept into the text on p.22: MacGillivray and Huxley’s scientific voyages in Autralisia in H.M.S. Rattlesnake took place between 1847 and 1850, not in 1884/5. Regarding the distribution of species, the author assumes his reader is thoroughly familiar with the Far Eastern region, thus the range of O. victoria epiphanes is stated badly as “San Cristobal, Bauro’’ which happens to be one of the Solomon Islands. This treatment might suffice if linked with individual distribution maps for each species, but on its own it hinders rather than helps the reader. The only map provided is a half-tone atlas of the Far East drawn to a very small scale which merely marks most of the place-names mentioned in the text; it is thus very difficult to get any visual idea of the relative distribution of different geographical races of certain species—and these are very numerous amongst the Birdwings. No doubt the few professional entomologists who are experts in this field may welcome this book for its pictoral excellence, but to the majority of us it will seem a luxurious accessory to the coffee-table. This is regrettable because the Birdwings deserve a definitive work and this will have to wait until the difficulties of studying these insects under natural conditions are overcome and the life-histories of many species have been recorded. In many places their rain-forest habitats are being destroyed in the name of economic progress, while the huge size of the females and the brilliance of the male specimens has made some Birdwing species such highly-prized collectors’ items that today a dealer can ask over £200 a pair for certain Ornithoptera, and in Taiwan and Japan there are various concerns geared to the commercial exploitation of these insects for decoration. It is hardly surprising that the conservation of the Birdwings in the wild before it is too late is now becoming a subject of increasing importance. In Papua, New Guinea the government has imposed a total ban on the unauthorised collection of these butterflies and set up a native butterfly-farm industry aimed at encouraging the export of specimens to accredited dealers only—probably the first time legislation has been passed anywhere to maintain a healthy local stock of insects and to develop their potential investment value at the same time! All these developments were taking place while Mr. D’Abrera was writing his book, so it is particularly sad to see nothing but a very passing reference to conservation or to the PNG scheme in its pages. But then this is essentially a beautiful book to be looked at, not a practical book to be used or referred to. N.H.C. BUTTERFLIES THEIR WORLD, THEIR LIFE CYCLE, THEIR BEHAVIOUR, by Thomas C. Emmel. 1976 pp. not enumerated (262): small Royal quarto. Thames and Hudson, London, Price £12.50. Oh dear! Oh dear! What a mess! This book has fallen between 82 MAY, 1977 several stools. It really doesn’t know what it has tried to be, but I think it is an attempt at futuristic typography and, as such, it makes me shud- der, the only decent thing about it being the use of grey tinted paper, ruined of course by the use of appalling typographic layout and the use of jet black to the margins of most of the coloured illustrations with the result that the book looks used and dirty even when new in the bookshop! Much of the white printing on the black paper is difficult to read. The text is set in one of two columns to a page. When in single columns the other half of the page may contain a figure legend; a small illustration; a subtitle; or just the page number. A good half of the pages do not bear a page number which makes finding ones way about by using the most inadequate index most frustrating. The “printing” is non-registered, like that of a typewriter, and in view of the way the text is set to maximise paper wastage, it would have been better to save on the cost of paper and spend the money on proper composition. There are no less than nine pages blank or bearing solely a chapter title. This is yet another expensive book that has been rushed into press without being proofread. There is the inconsistent use of capital letters and many misspellings of scientific names; For instance :—welskei for weiskei; kayuga for kaguya; batava for batavus; mani for manni; venatus for venata; xerces for xerxes;. These are just the ones we happened to notice and know of. Two of the above were in one figure legend. How many others, pray, go undetected? We also have such statements as the legends of Fig 234. “Mourning cloak or Camberwell beauty (Nym- phalis antiopa); Britain” but, Fig. 235. “Peacock butterfly (Inachis io): England,” Fig 149 labelled Apatura ilia is A iris, a fact correctly stated in the index and where on earth and by whom was Colias australia (Fig. 287) originally described. To our mind carelessness of this order is quite inexcusable, insulting to the intelligence of the potential reader, and certainly unacceptable in a book of this price range. Most of the coloured illustrations are good and the subjects well chosen and well printed. We have again however a pair of the stools between which the book has fallen. All of the doublepage and some of the single, are too large and need to be viewed, as does a painting, from a distance of several feet. When this done they are most effective, but who wants to study a book that way. The text is obviously by an author who knows his subject and contains many interesting anecdotal facts and observations about butterflies, marred, as already mentioned, by lack of proofreading. That reputable publishers are churning out this sort of atrocity is appalling but a sign of the lowered standards of present day remote control business. Perhaps our younger members like this sort of production. To my mind the best way of preventing its future occurrence is to leave it on the shelves of the bookshops. BOCG. AES BULLETIN, Vol. 36 83 NATURAL HISTORY AUCTIONS 1700-1972, by J. M. Chalmers- Hunt, pp 189; Sotheby Parke Bernet Ltd. 1976. Price £12.50. It has to be acknowledged that the appearance of a book purporting to be a history of auctions is not calculated to precipitate a rush to secure copies, yet this pioneer work, compiled by Michael Chalmers-Hunt and containing valuable introductory articles by him and other well known specialists, possesses considerable merit and abounds in interesting detail. These articles cover 51 pages out of a total of 189, the remainder consist- ing of a chronological Register of Natural History Auction Sales. That the new book is an important adjunct to such reference works as Hagen (Bibliotheca Entomologica, Leipsig 1862/63) and Horne & Kahle (Ueber entomologische Samlungen, Berlin 1935/37) is unquestionable. This review is of necessity concerned with the entomological aspects rather than with the other branches of natural history covered, and in this context the attention of the reader will first be caught by the Editor’s eleven-page article which displays his wide knowledge of entomological history. Writers on this subject are well aware of the paucity of information extant on some of the early entomologists whose names are well known to us. Many of these persons do not find a place in the Dictionary of National Biography and biographical memoirs are practically non- existent in the earlier volumes of our older periodicals and ‘Proceed- ings’ of societies. Thus in the case of John Francillon (1744-1818), his profession has variously been stated to have been that of a doctor and a jeweller. Both the Editor and the Reviewer also, in a recent publication, followed H. A. Hagen (1862/63) in stating that J.F. was a doctor. This had been questioned by a correspondent and the Reviewer has established from City records that the address given on the sale catalogue, 24 Norfolk Street, Strand, London refers to premises which at the material time were occupied by J.F. and his Partner trading as jewellers. The new book contains its surprises: Thomas Vernon Wollaston (1822-1878) and J. R. le Breton Tomlin (1865-1954) both well known as coleopterists were malacological experts also, and Wollaston’s extensive collection of shells was sold at auction. Other entomologists are also shown to have worked in fields other than their own. Incidentally, two Wollastons are indexed and the Reviewer suspects that the initials J.V. on the catalogue of May 29th, 1894 sale, which he has verified, are an Auctioneer’s error, and that the collection of Atlantic coleoptera sold on this occasion relates to T.V.W. Much care has been expended by the Editor on the compilation and verification of the Register and his enquiries over a wide field have involved a large number of his friends and correspondents, as he acknowledges in his Preface. As a result, this well-produced and attrac- 84 MAY, 1977 tive book is not only remarkably free from error but is highly informa- tive. It is impossible to peruse the new book without a feeling of nostalgia and even of sadness and in the personal opinion of the Reviewer, reading of the introductory on Ornithology should, in the interests of conservation, constitute a compulsory duty for all entomologists. Copies of the book which is published in a somewhat limited edition, are obtainable direct from the firm at 36 Dover Street, London W.1. or from E. W. Classey Ltd., Park Road, Faringdon, Berks. C. MacKechnie-Jarvis ARTHROPOD VECTORS OF DISEASE by James R. Busvine pp. (4); 67, 8vo, Edward Arnold 1975. Price £2.60 (hardback); £1.15 (paper). After reading this book one wonders how the human race has ever survived in the tropics, let alone increased to the overpopulation condi- tions prevailing today. That it has done so is due in fact to the large measure of control, achieved during the past 150 years, over the factors causing transmission of the many lethal diseases transmitted by Arthro- pods, coupled with some degree of resistance being built up over the millenia by the local population involved. In large areas of the tropics today however these control measures are being negated by the slums caused by overpopulation and by political reasons. This book is a plain and factual account of the many appalling diseases that are transmitted by Arthropods—most of which are of course insects—and their respective importance is assessed; the problems that have arisen in their control; possible prophylatics and preventitive measures; attempts at curing the diseases. Many of the diseases transmitted are caused, not by bacteria, fairly easily curable with antibiotics, but by viruses, rickettsia and trypano- somes and it is not perhaps sufficiently realised that there is no known cure for most of these diseases. They are mostly chronic and debilitating rather than short and spectacular, occur in poor areas of the world and do not therefore attract their fair share of research funds and attention. This is a book which should be read by anyone considering a trip to the tropics, and will also be of use to nurses and those interested in Public Health. Professor Busvine is to be congratulated on assembling all the facts together in such a concise and readable form. GENETICS AND ADAPTATION by E. B. Ford, F.R.S. pp. VI: 58. 8vo. Edward Arnold 1976. Price £2.60 (hardback); £1.15 (paper). This is no 69 of the Institute of Biology’s excellent studies in Biology series. As might be expected from this well known author the subject matter is largely Lepidopterological and is a concise explanation of the subject. In addition it is an absolute mine of useful and interesting in- AES BULLETIN, Vol. 36 85 formation. To give two examples, how many people know that a rather small bird, the Quail, can eat a dose of digitalis sufficient to kill 50 men! Secondly that a Blue jay having tried to eat a Monarch butterfly will starve to death rather than risk the taste of another! Some elementary knowledge of genetics is assumed in the reader. To those who have this, various research projects, entirely suited to the Amateur Entomologist are suggested and others may well spring to mind. There is a useful bibliography but, alas, no index. This is an interesting and stimulating booklet whose only fault is that of being too short. THE DYNAMICS OF COMPETITION AND PREDATION by Michael P. Hassell pp (4); 68. 8vo. Edward Arnold 1976. Price £2.60 (hardback) £1.15 (paper). Definitely a book for the mathematically initiated, being full of graphs and equations. This is another study from the Institute of Biology’s stable and in spite of the rather general title, some ninety per cent of the examples and work quoted comes from the insect world. Although these are drawn chiefly from parasitoids (e.g. Nemeritis on Ephestia) and the inter-relationships of beetles the relevency of the subject to the understanding of the decline and extinction—or conversely the spread—of butterflies and other species is obvious. To those keenly interested in this subject and who can follow the rather technical argu- ments, this book should prove extremely interesting as it is a concise summary of the multitude of variable interrelating and complex factors involved. It is not for the faint-hearted nor for our younger members with less than A-level maths. A criticism which I hope will be remedied in any second edition is the objectionable omission of the title in the reference list. It would have been useful, also, to have had even a brief index. S.C. NOTES AND OBSERVATIONS SOCIETAS EUROPAEA LEPIDOPTEROLOGICA :—We already have a “Lepidopterist’s Society” which is American based. Now a European Society with similar aims has been founded. Information concerning this society is as follows. In the spring of 1976 R. de Jong and O. Kudrna issued an appeal to European Lepidopterists to form a European Society for lepidopter- ology. The response to this appeal was so good that by the summer of 1976 almost 100 lepidopterists from 17 European countries had indicated their willingness to join such a society to be known as:— SOCIETAS EUROPAEA LEPIDOPTEROLOGICA (SEL) The Inaugural Meeting took place in Bonn (Germany (BRD) }} at the weekend September 18-19, 1976, in the Zoologisches Forschung-institut und Museum A.

OBSERVATIONS OF PARTIAL GENERATIONS OF LEPIDOP- TERA IN 1975 AND 1976:—The two seasons of 1975 and 1976 will live long in entomologists memories. I will concern myself only with the partial generations of Lepidoptera I have noted. AES BULLETIN, Vol. 36 87 On the 15th August 1975 at Beddgelert, North Wales, I saw a perfect male Small pearl-bordered fritillary (Boloria selene D. & S.) In the same month my friend Jon Foster captured a perfect male Small blue (Cupido minimus Fuessly) at Portsdown hill, Portsmouth. The following year, on 9th August, 1976, I captured a perfect male Dingy skipper (Erynnis tages L.) at Worth Matravers, Dorset. In the season of 1975 I have captured fresh Holly blues (Celastrina argiolus LL.) and Speckled woods (Pararge aegeria L.) during mid- October. The Speckled woods captured then are similar to those of the first normal generation captured in April. In August 1976 large numbers of Ruby tigers (Phragmatobia fuliginosa L.) were captured on the Isle of Purbeck, Dorset. These observations tend to show how favourable conditions have been for breeding and ‘feeding up’ in the past two seasons; this was in spite of the drought that made Southern England look like the Serengeti. It is a wonder how many species managed to find enough food to survive and give us a season to remember : —David Rees (5510J) and Jon Foster. MORE CONVOLVULUS HAWKMOTH RECORDS:—On the night of 22 September, 1976 a female Agrius convolvuli L. was caught in a mercury vapour light trap situated at Hayling Park, Hayling Island, Hampshire: —John Walters (5904J) While on weekend visits to Norfolk I was privileged to find both adult and larva of Convolvulus hawkmoth! My first find was of a full-grown larva at Hemsby, Norfolk, on 23 July, 1976. Most un- fortunately, while being carried around in my rucksack, in a polythene bag half full of nice pupating medium, it made its escape, undiscovered by me until my return home... The second sighting was of an adult and this took place over a month later, on August 30, 1976 at Aldeburgh, Suffolk: —R. A. Softly (5734) [See photograph Fig. E.—Ed.] BUTTERFLIES ON MUD: —With reference to this subject, I have seen a Purple hairstreak (Quercusia quercus L.) imbibing where pond water has been splashed onto the banks on Wimbledon Common. I would also like to draw members attention to the remarks made two centuries ago by Moses Harris in the preface to his English Lepidoptera where he says “In hot and dry days it is common to observe the Butterflies settle in numbers on the mud in ditches and I have often seen above twenty so close together as to be contained within the circumference of a small hoop; by which it is found that heat with moisture best agrees with their nature.’—R. A. Softly (5734) CONGRATULATIONS: —For his services in saving and conserving the sites of the Large Blue butterfly an MBE was awarded to Allan Kennard in the New Years Honours list. 88 MAY, 1977 RED ADMIRALS IN SCOTLAND:—On the 5th October, 1976 and again on the 8th, whilst working at Coulport, Loch Long, Scotland, I saw 2 Red Admirals, both sunning themselves on a brick wall. This was the first time that I have seen this butterfly in Scotland. Two weeks later, on the 22nd October, 1976, whilst working at Loch Goil, I again had the fortune to see a Red Admiral.—_J. Green (4932) ENVIRONMENTAL STUDIES:—tThere are a wide range of courses on this subject available at lovely Madingley Hall. In addition some natural history field courses are run in centres such as the Lake District. Suffolk coast and West Scottish Highlands. The courses are open to all interested and details are obtainable by writing to The Director. Cambridge University Board of Extra-mural Studies, Madingley Hall. Madingley, Cambridge, CB3 8AQ. PARASITIC CHALCID WASPS—HELP WANTED:—These nasty- or beautiful-little animals (it depends on your point of view) are often brilliantly coloured and with a metallic sheen. Their favourite food. as grubs, is the egg/larva/pupa stage of other insects. Indentification of the many hundreds of British species alone is extremely difficult. Dr. R. S. George, better known of course for his persistent studies and appeals on fleas from birdsnests, has now turned his energies to the study of these and would greatly appreciate receiving bred snecimens, together with their hosts and accurate data. His address is 8, St. Peter’s Street, Duxford, Cambridge CB2 4RP. VANISHED HEDGEROWS:—It has been reported by Mr. Ian Purdy, Cambridgeshire County Planning Officer, that 80-90% of the County’s hedges and 80% of its Frogs have been lost over the past 20 years. He goes on to say that the advent of the EEC Agricultural policies will result in further changes in the landscape. When such destruction is taking place, is it any wonder that our insects and other fauna and flora get fewer and fewer. More and more presure needs to be put upon politicians (which includes local Councillors) to get them to pass legislation or take such other measures as will put a stop to this constant despoliation of our landscape : —Editor MOISTURE DRINKING OR CLEANING? :—A casual observation made in July of 1976 may be of interest to our members and may also answer questions posed in our Bulletin over the past years. Whilst sitting in brilliant sunshine enjoying the sight of several butterflies on the Buddleia bush close by, I paid particular attention to a rather splendid Peacock /narchis io, Linn., dipping its proboscis deep among the flowers. After several minutes of feeding it would then alight on the grass close to where I sat and edge its way to a damp patch caused by overspill from my children’s paddling pool. N.B. Before water restrictions! Once there it would carefully extend its proboscis, heavily coated with pollen from the Buddleia flowers, then with the AES BULLETIN, Vol. 36 89 a tarsus of the foreleg it would stand on the proboscis close close to the palpi, pressing it to the damp earth beneath: It would then draw out _ the proboscis from under the tarsus and repeat this procedure several _ times until the proboscis was clean. Jo would then resume feeding for _ some long while repeating the cleansing process later. Without my closer examination of io’s activity, which at first I thought was another example of moisture drinking, the above observation would not have been reported. It is possible that this is a widespread cleaning habit of several species of butterflies and could easily be mistaken for moisture drinking. Any comments or similar observation notes would be appreciated : — _M. S. L. Simpson (4859) ECOLOGICAL STUDY OF WOOD WHITE:—The Wood White butterfly, Leptidea sinapis (L.), is usually, though not always, associated with woodland and occurs in parts of southern and western Britain. Although the distribution is patchy the species is often abundant locally, making it especially suitable for a population study for which I have tecently been awarded a grant from the Natural Environment Research Council. The basis of the project will be a detailed investigation of the factors determining its abundance, with particular emphasis on the potential for habitat management to help to ensure its survival in an area. The value of this project will be greatly enhanced by the knowledge of local entomologists and it would be greatly appreciated if those who are familiar with the butterfly, either in Great Britain or abroad, could contact me. In particular I would be interested in details of extinctions, _ introductions or natural colonizations as well as site details such as _ habit-type, larval food-plant species, and the timing and length of each brood. Details of localities will of course be treated in strict confidence should that be requested: —-M.

Box 505, Kinderhook, New York 12106, USA. 90 MAY, 1977 - OBSERVATIONS ON DOROS CONOPSEUS Dcros conopseus Fab. is a very handsome and rare fly. It is a member of the dipterous family Syrphidae (hoverflies) and although rare, I have been privileged enough to see a good deal of it in the last year. The first that I heard of it was when my father Mr. A. W. Jones took a specimen on the 29th June 1969 on a leaf of Eupatorium cannabinum (Hemp agrimony) in Friston Forest, near Eastbourne. Six years later my good friend Mr. R. Dumbrell took up Diptera and went to Friston Forest to look for it. He found one, not in the same locality, but about a mile away. The specimen he took was like my father’s, a female, and was taken on a flower on June 14th, 1975. Doros seems to be well established in the forest, for Mr. Dumbrell has taken it there again this year. This time however in yet another part of the forest near Friston Place. Friston Forest is a good locality for the insect, however, I have been lucky enough to find Doros in three other places in Sussex. The first on the South Downs behind my home in Newhaven. On June 17th, 1976 I took one above Denton (in the Parish of Newhaven). It was on the wing hovering slowly about a bramble bush. On the wing, before I realised what it was, it had the appearance of a Crabrowasp, its yellow and black banded body being very prominent. Later on the 23rd of June I found another specimen not far from Denton, also flying around a bramble bush on Forehill (South Heighton). On the third occasion I was lucky enough to see Doros in some num- bers (5 seen of which 3 males were examined). This unusual abundance was at Arundel Park on June 28th, 1976. At Arundel the flies were not all in exactly the same area but in various parts of the northern end of the park. They were hovering over logs and around bushes but none _ AES BULLETIN, Vol. 36 91 settled. The flight of all the specimens I have seen has been sluggish and a little erratic not in my opinion at all characteristic of hoverflies _ which are usually strong and swift fliers. I would be interested to hear from anyone else who has taken Doros in the last year. It will be interesting to see if this abundance is peculiar to Sussex or widespread. It will also be interesting to see the abund- ance witnessed this year will occur again in the next. Richard Jones (5612) A PRELIMINARY SURVEY OF THE FOOD AND FEEDING HABITS OF ADULT BUTTERFLIES (FIRST SUPPLEMENT) (Continued from Vol. 32, p. 181) NECTAR-PRODUCING FEEDING PLANTS INFREQUENTLY VISITED BY BUTTERFLIES It is noticeable that some flowers, although obviously producing nectar rarely seem to be visited by butterflies. Examples are :— 1. Epilobium hirsutum L. (Onagraceae) Hairy Willowherb. This plant seems only to attract Pieridae. Pieris rapae L., P. brassi- cae L., P. napi L. and Leptidea sinapis L. have been personally recorded and Knuth (1906) gives just ‘Pieris spp.’ 2. Pelargonium zonale (Geraniaceae) Zonal Geranium. Aglais urticae L. and Gonepteryx rhamni L. (male) are the only personal records, and these isolated cases. 3. Tropaeolum majus L. (Tropaeolaceae) Garden Nasturtium. Flowers were seen to be visited by a single A. urticae L. which fed or attempted to feed from one yellow and one orange bloom. The long nectary suggests lepidopterous visitors, but no other butterflies have been seen to visit it, nor do there seem to be any moths attracted after dark. 4. Syringa spp. (Oleaceae) Lilac. Butterfly visitors are few on this shrub: Polygonia c-album L. and Callophrys rubi L. on White Lilac and G. rhamni on Double-white variety. No records for the mauve varieties. 5. Choisya ternata (Rutaceae) Mexican Orange. Here again the only recorded visitors are the Pierids P. rapae and P. brassicae. 6. Daucus carota (Umbelliferae) Wild Carrot. Owing to its shallow nectaries the Wild Carrot is not an obvious choice as a feeding plant for butterflies. In Britain I have noted it visited by Limenitis camilla L. (a very brief settling) and certainly by Aphantopus hyperantus L. In France, however, 6 species of butterflies were seen to visit it frequently: —Maniola jurtina EA 92 MAY, 1977 C. rubi, Nordmannia ilicis Esper., Coenonympha pamphilus L., Heodes tityrus Poda and Thymelicus lineola, ochs., as will be seen, mostly small insects suited to shallow nectaries. Avebury (1903) quoting H. Muller gives only two lepidopterous visitors (unspecified) to Wild Carrot as compared with 19 species of Diptera. 7. Rosmarinus officinalis (Labiatae) Rosemary Very attractive to bees, Apis and Bombus but no butterfly visitors. It would be very interesting to know the reason why these plants, and many others, are to a greater or lesser extent largely ignored by butterflies. Could it be: —(a) Erratic nectar production, (b) Un- suitable colouration, (c) Dependency on location, (d) Unattractive scent (i.e. to the insect)? Again, why is Daucus carota more attractive in France? BUDDLEIA Even the non-lepidopterist is aware of the attraction that Buddleia has for butterflies, and it is known by many as ‘The Butterfly Bush’. Belonging to the family Loganiaceae there are quite a few species and varieties, some blooming quite early in the season, before the nymphalids are really under way. I have made a particular study of four varieties of Buddlei davidii, and of Buddleia globosa all of which I have planted in my garden. They are: — Buddleia davidii a. The common pale mauve variety. b. var. ‘Black Knight’ which is a very deep purple and from a few yards away appears black. c. The purple variety. d. The white variety. The pale mauve comes into bloom at the end of July together with ‘Black Knight’ while the purple and white begin a week or so later, but are still in bloom when the first two have begun to fade. Buddleia globosa, however, blooms earlier and my specimen is in flower for the last three weeks in June and quickly fading. During the last few summers, 1975 in particular, I have made the following general observations: a. The pale mauve variety does not appear to attract any butterflies for the first week of blooming. b. The species is equally attractive to night-flying moths, Noctuidae, Pyralidae etc. c. The varieties with the longest corolla-tubes attract butterflies, the larger moths and bumble-bees. d. The variety with the shorter tubes (e.g. “Black Knight’) attracts principally the smaller moths, Pyralids, Plumes, Crambids etc. and is used by butterflies and the larger moths as a second choice from the mauve variety. ‘Black Knight’ also attracts honeybees which do not as a rule frequent the mauve. | ! AES BULLETIN, Vol. 36 93 e. Buddleia globosa attracts myriads of honeybees, few Bombus, many Pyralid moths (particularly Eurrhypara hortulata L.) but so far only one butterfly Aglais urticae L. and that an isolated incident. Dealing with each variety in more detail: — Buddleia davidii (Common, pale mauve, -Corolla-tube 8-10 mm) An observation made in a disused chalk-quarry in Hampshire, 10-8-72 where there are some dozen or more self-sown pale mauve bushes, showed that although in bloom and in fine weather conditions no butter- _ flies were attracted, most species seen were feeding from marjoram. A similar observation was made this year in my garden where, for the first week of blooming there were no visitors. Even allowing for the fact that the usual nymphalids were perhaps not yet flying. I particularly noted that the numerous Pierids completely ignored the bush. It would appear that for the first week or so of blooming nectar secretion must be too low and the presence of a rival source is a greater attraction. My list of butterfly visitors to the mauve variety amounts to 24 species, but I have noticed that two species ignore Buddleia and they are Aphantopus hyperantus L. (which is common in my garden) and Colias crocea. Fourcr. (Stallwood 1973) Observations after dark show that this variety is favoured principally by the larger moths such as Triphaena pronuba L. Plusia gamma L. Xylophasia monoglypha Huf. Leucania pallens L. Mamestra persicariae L. Scoliopteryx libatrix H. Plusia chrysitis L. etc. and to a lesser extent by Pyralids, Crambids and other small moths. Buddleia davidii (var. ‘Black Knight’ -corolla-tube 6-7 mm) This is altogether a smaller plant with smaller trusses of bloom. It is visited by butterflies more as a second choice, but at night it is mainly, but not exclusively, favoured by the smaller moths such as Alucita spp.. Lithosia spp., Pyralids, Crambids etc., but with the occasional T. pronuba and P. gamma. On one occasion a specimen of Ourapteryx sambucaria was seen feeding with wings folded ‘butterfly’ fashion. Buddleia davidii (Purple variety -Corolla-tube 9-10 mm) Buddleia davidii (White variety -Corolla-tube 9-10 mm) These varieties are in full bloom by about 18th August when the common mauve is long past its best and is relying on its secondary blooms. Both Purple and White appear to have an equal number of butterfly and moth visitors which at this period are forsaking the Mauve variety. Buddleia globosa (Corolla-tube 4 mm) yer The short length of corolla-tube would indicate that this species 1s more suitable to small moths and honeybees, and observations bear this out. FEEDING AND TEMPERATURE Observations in 1975 brought to light several instances of behaviour of butterflies feeding at flowers I had not previously noticed. While 94 MAY, 1977 endeavouring to photograph nymphalids on Buddleia during a very hot spell (well up into the 80’s), in addition to the insects being very active, as is well known, it was noticeable that A glais urticae, Polygonia c-album and Inachis io often fed with wings tightly shut with occasional fanning. The reason for this was evidently to exclude radiant heat. A day or two later in a cooler spell the reverse behaviour was apparent. The majority were feeding with wings fully spread or half closed (i.e. at an angle of 90 degrees between them) in this case presumably to absorb radiant heat from the sun. The above observations were made at the beginning of August, but later on in the second week of September on a sunny but cool day A. urticae, P. c-album, Vanessa cardui and V. atalanta were behaving in a similar manner, mostly with fully spread wings or at 90 degrees in sunshine. However, when the sun was obscured many settled on the lawn with wings flat and motionless, evidently to absorb all heat possible, and to resume feeding as soon as the cloud passed over. In these cool conditions even the Pierids (which usually feed with closed wings) were imbibing with partly open wings and one Pieris brassicae was noticed with wings almost fully spread, which is most unusual. By chance I came across a reference by Kubo (1960) which to a certain extent bears out the above observations. He states that in Japan “Some of the spring brood butterflies (i.e. those resulting from hibernated pupae) keep the wings open while drinking, but others of these and all summer brood individuals, drink with their wings closed.” B.

Fabre’s work entitled “The Life of the Caterpillar’ published in English in 1912, he wrote several chapters concerning the “stinging” phenomena in the Pine Processionary (Thaumetopoea processionea L.) and the “Arbutus” caterpillar now known as the Brown Tail (Euproctis chrysorrhoea L.) His simple, but effective, experiments established that the irritant substance is inherent in all species of Lepidoptera, in the blood of the larvae, the frass and upon the hairs if present. But the precise nature of the irritant chemical, its concentration in the blood, frass and hairs has not been fully elucidated. The area of insect urtication is wide open to investigation as he wrote”...The last step remains for us to take, AES BULLETIN, Vol. 36 95 namely, to isolate the stinging element and obtain it in sufficient quantities permitting of precise enquiries into its nature and proper- fies’: ..” The family the author intends to deal with, in connection with its urticating properties, is the Lymantriidae. The area in which the author lives is particularly well endowed with species of several genera, namely: Dasychira, Euproctis, Orgyia and Lymantria. Most of. the urticating properties observed were gained as a result of painful personal experience. The Lymantriids or Tussock-moths are a small group of species of rather diverse habits. One hundred and ninety-four species occur in the Palaearctic region, of which eleven species occur in the British Isles. These are further subdivided into six genera. The most interesting genus from the point of view of urtication studies is perhaps Euproctis, of which the only British representatives are E. chrysorrhoea L., and E. similis Fuessl. E. chrysorrhoea is gregar- ious at all stages of development, and to some extent polyphagus. The ova of this species are laid in large batches of over a hundred and covered with hair from the anal segments of the female. The larvae hatch within about three weeks and they produce a small tent of several sheets of silk, normally at the apex of the plant. When still small they hibernate and do not resume feeding till early spring of the next year. About June the larvae when fully grown pupate in a small silken cocoon consisting of silk and hairs from the last integument. The imagos hatch in July. At all stages of its development this species is irritant. The anal hairs, the larvae, the cast skins, the nest and the condition known as Urticaria can be caught from the adult moth. This leads naturally to the question, can we with any certainty predict the degree of irritance from the behaviour of the species throughout its Stages? In Table 1 the prediction as to the virulance of the urtication was based upon whether the larvae were solitary or gregarious, or if they possessed a coat of hair. The predictions were based upon the assump- tion that if a species has a hairy coat, and is gregarious by nature then it is likely to be irritant. In the species which were examined, all the predictions were correct except for E. similis. Although the larva of this species is extremely hairy, it is solitary when in the final instar. Experience tells us that it is very painful to interfere with. This can perhaps be explained when more details of its life cycle are reviewed. The ova are laid in batches and the larvae remain in gregarious colonies until a short time before pupation. The Table deals exclusively with British species, but what of some of the European fauna? The example the author took from the Euro- pean list was T. processionea. This was moderately common on estab- lished oak trees in Central and Southern France in 1973 and 1974.

If we know a few of the details of the life cycle of T. processionea we can hopefully predict whether this species is urticat- ing based on the details given in the Table. The ova are laid in batches covered in an anally spun web of threads, which is irritant. The larvae are once more communal, making their way to the Jeaves in long columns. During the day the larvae repose in a huge dome shaped nest which is spun against the trunk of a suitable tree. After contact with larvae of an urticating species, examination of the infected spot seldom reveals any implanted hairs, so what can be the mechanism by which the irritance affects the skin, and causes imflam- mation? If the hairs of the Garden Tiger (Arctia caja L.) are examined under a high power microscope they are well barbed with pointed lateral projections, but A. caja causes no infection of the skin. However there are species which can implant countless hairs and not cause any irritation. For example, contact with a cocoon of Dasychira pudibunda, leaves the examiners fingers looking like a pincushion. The hairs of both these harmless species are neither grooved or hollow. This is the case with the hairs of E. chrysorrhoea which also lack a groove or hollow interior, yet these hairs as already mentioned are most virulent. It has been suggested that the irritant is spread on the hair, the hair being simply the vector. The hair is used to cause a minute puncture of the skin, enough to allow the irritant to enter the wound. But the chemical which causes the irritation remains undefined chemically although it would be probably a by-product of metabolism. Mark Hadley (5315) BREEDING PUGS How much I agree with P. A. Sokoloff (A.E.S. Bulletin, 35, pp 148-9) in his views on breeding Pug larvae. When I was a naive and enthusias- tic tyro I discovered the fascination of Pugs and resolved to breed them all. I religiously sterilized my breeding tins and changed the food of the little beasts every day. I pampered them with clean tissue paper and caressed them with fine camel-hair brushes. I watered them and gave them air and cherished them as my children and what was the result. You’ve guessed it. They died! Some dried out and others drowned; some were parasitized and some got fungus, some emerged as cripples but most just vanished. They just disappeared and I’ve a shrewd suspicion that many of them were discarded with the day old food plant. Well, I soon learnt my lesson. This isn’t really the right answer in the end, I know, and the late Mr. P. B. M. Allan will be revolving in his grave but for me the secret of rearing Pug larvae is to ignore them. Just refuse to look after them at all; spurn their anguished cries for help 98 MAY, 1977 and firmly turn your back on their feeble wanderings. Nowadays if I find some nice larvae, some expallidata, for example, or a clutch of absinthiata, | bung them onto a | inch layer of peat with their flower heads in a sandwich box, I put on the lid, and I forget all about them. Well, alright, that’s not quite true; if the lid is too close fitting I mop up the sweat now and then and I always make sure that I don’t put in too many flower heads. Leave a nice space around the sides of the box and don’t pile the flowers up, that’s the rule. Otherwise I really do just leave them alone. If they were reasonably well grown when collected their food will last quite well unchanged and they will pupate, but heaven knows where. Don’t dare to look or you will end up throwing the lot away in despair. Just wait. Sure enough, in their own time, the moths will emerge and often in embarrassingly large numbers. You will be able to boast that you let most of them (where you found the larvae, of course). But then you won’t have learnt much! Back to the drawing board. Mark Young (3759) A DEVASTATING ATTACK BY PTEROMALUS PUPARUM L. (HYMENOPTERA-CHALCIDOIDEA) For many years I have been breeding the smail gregarious fritillaries in captivity. My stock of the Glanville Fritillary, Meltitaea cinxia L., has been around for a long time and I have a colony established locally from it on a nearby railway embankment where it leads a precarious existence due to firing by the local vandals. I always keep a large stock in cap- tivity, both for possible release and to ensure a wide gene mixture in breeding. This summer I had about four hundred larvae in the last instar in two cages when I left for two weeks collecting abroad. Ample foodplant had been left for them and I anticipated them to be all pupated by the time of my return. One cage had about fifty larvae in it and the other more than three hundred. On my return I could not find any pupae or larvae in the larger cage and then discovered that the netting cover had been dislodged and I found the pupae in large masses pupated beneath an upturned container beside the original cage. They were in solid rows, some having spun webs around other pupae. I carefully detached them and placed them into a new cage and awaited their emergence. Those in the smaller cage started to emerge within a few days of my return and paired and laid but none were to be seen in the larger batch. About twelve days later I noticed several small wasps in this cage and on examination found several pupae with holes in the sides. I then broke open several more pupae and found them full of white grubs or the pupal wasps. To cut the sad story short it turned out that every one of the pupae had been attacked and thousands of wasps eventually filled the cage. The wasps were kindly indentified for AES BULLETIN, Vol. 36 99 me by Dr. M. Shaw and I hope that this experience of mine will act as a warning for others. No matter how carefully you go about your breeding arrangements, it is essential that your cages or sleeves are completely insect proof. If the mesh is slightly too large these small Wasps can enter and wreak havoc. The smell of a large congregation of larvae must attract large numbers of them to the area and they will alight on the larva waiting until it sheds its last skin. Then while the pupal shell is still soft it will deposit its load of destruction. One can see now why it is essential for gregarious species to split up and wander off to pupate—if they did not they would be a sitting target for these wasps. The species P. puparum seems to be very wide in its host preference and I have had them from the Wall. Lasiommata megera L.. the Swallowtail, Papilio machaon L. and both the Marsh fritillary, E. aurinia Rott., and the Heath fritillary, Mellicta athalia Rott. this year. In each case the larvae have been exposed in the last instar and on each occasion there has been a total kill. P.. W...Cribb..(2270) PHOTOGRAPHING LEPIDOPTERA I have always been interested in butterflies and moths but the collec- tion of actual specimens does not appeal to me. However. I do not condemn collecting by others and have no wish to enter the long running battle between collectors and photographers. Both pursuits have their good points and it should be a matter of personal preference so long as the Code for Insect Collecting is not overlooked. I might add that the most dedicated collector that I know normally breeds insects for his collection and by releasing the surplus stock in the parent’s original habitat could well be responsible for increasing the number of moths reaching the adult stage and making life difficult for their parasites. I am building up a collection of colour slides as I have found prints too expensive and unreliable as to colour rendering. I use a hand held Praktica single lens reflex with automatic pressure diaphragm and a 3 dioptre close-up lens. I take every slide by flash, even in sunlight, in order to use the smallest stop to increase the depth of field and eliminate camera shake. I usually expose at f22 focussing as near as possible and consistently achieve correct exposures. Some light-coloured species such as The Large white (Pieris brassicae L.) would be over-exposed unless a baffle (e.g. one or two layers of white handkerchief) is placed over the flashgun. Compared to some equipment described in earlier issues of the Bulletin and in journals aimed at photographers rather than entomolo- gists my outfit is primitive and my technique not much better, yet I manage to take acceptable pictures. Ideally. I suppose. I should use the pabulum or an appropriate plant, 100 MAY, 1977 rock etc. as the background and I am slowly acquiring a variety of materia] such as the bark of different trees. I have used rough slate quite often as the general background as there is virtually no light reflection and the neutral colour of the slate emphasises the colour of the wings and body of the insect portrayed. Day-flying and night-flying species require different approaches. In daylight there is no difficulty with those obliging insects which sit calmly on fences or tree trunks, but real cunning and perseverance is needed to get a good picture of a Meadow brown (Maniolo jurtina L.) which is not partly obscured by grass stems—particularly if you are trying to snatch a shot of one with its wings open for a second or two! Nervous and fast-flying species can induce the “thrill of the chase” as I dash after those specialising in erratic flight over uneven ground trying to spot where they land. I learned all about flash colouration in the field. At night I usually collect moths in pill boxes and photograph them in daylight the following day when they are torpid. They are released that night where they were taken. If the return journey will not be possible the moths have to be photographed on site. This is where the slate is useful for I cannot carry all possible backgrounds with me and the site itself may not provide something suitable. When using a mercury vapour lamp there is enough light to focus by, but if the moth is at sugar a friend is needed to illuminate the moth while the picture is taken. Identification in the field can be almost impossible with some species as I cannot always see the hindwings of those moths which sit with their wings flat or the upper surfaces of those which sit with their wings raised. Nor does there seem to be much in the way of published colour pictures of lepidoptera in their natural resting positions. If only there were some cheap, easily available, lightweight, wear and weather-proof, well keyed complete guide with illustrations like those in the booklets published by Jarrold Colour Publications, Norwich (text by George E. Hyde). Pending realisation of this pipedream perhaps other members with greater experience than mine could publish hints on quick identifi- cation of troublesome species which do not require examination of genitalia or damaging the insect in any way. As an example I would like to be able to distinguish between the Treble -bar (Aplocera plagiata L.) and the Lesser treble-bar (Aplocera efformata Guenée) at sight. A comparison of types is not possible in the field. Ian Brydon (5881) ~_= Published June 15 by the Amateur Entomologist’s Society, 355 Hounslow Road, Hanworth, Feltham, Middlesex. Printed by V.B.

Council of the AES wishes to inform all members that the opening time of our exhibition this year will be strictly adhered to. Only permitted Traders and Exhibitors will be allowed into the exhibition hall before then in order to set up their stalls and exhibits. Due no doubt to our exceeding popularity, members and visitors have been arriving earlier and earlier to our exhibition over the past few years. Last year was rather chaotic due mainly to large numbers of peop'e arriving before official opening time and milling around the tables before either Traders or Exhibitors had had time to get themselves properly set up. This is not fair on anyone, least of all on those members who arrive with exhibits and then cannot get through the crush to set them up in comfort. Our venue will again be University College School. This year the exhibits are to be set out in the upper hall, not the gallery, and, in order to avoid overcrowding, the space occupied by traders will be restricted so as to allow more room for the customers. LADY-BIRD Lady-bird! Lady-bird! pretty one, stay, Come sit on my finger, so happy and gay. With me shall no mischief betide thee: No harm would I do thee, no foeman is here, I only would gaze on thy beauties so dear, Those beautiful winglets beside thee. From “Times Telescope” 1823, upon the discovery of its utility as a devourer of aphids! ANNUAL REPORTS FOR 1976 OF THE COUNCIL The Council is pleased to record that, despite the capricious nature of the National Economy, the Society has continued to prosper. Three factors appear to be responsible for our success: the expert management of the Society’s finances; the enormous amount of voluntary work carried out by Officers of the Society; and perhaps most importaut of all, the continued support of our members. 102 AUGUST, 1977 On 31st December, 1976 the Society had 1368 members, comprising 7 Honorary, 3 Life, 29 Affiliate, 308 Junior and 1021 Ordinary members. There were 244 new members, 12 reinstatements and 164 losses through death or non-payment of subscriptions, representing a net increase of 92 over. 1975: Four issues of the Bulletin were published under the Editorship of Mr. B. O. C. Gardiner, containing a record 196 pages of text, 15 half tone plates, and numerous other illustrations. Council hopes to further increase the size of the Bulletin during 1977. A new membership list was published in August, and two leaflets revised for distribution during 1977: “Collecting Lacewings’ and ‘Insect Light Traps’. However, the major publishing event of the year was the introduction of a ‘Lepidopterist’s Handbook’ by Dr. Richard Dickson. Sales of publications continue to be satisfactory, and Council records its thanks to Mr. Christie for his work as the Society’s Publication Agent. The Council met on six occasions during the year. The Annual General Meeting was held in March at Caxton Hall, and presided over by Mr. Cooke. Mr. M. Tweedie gave an excellent talk on insect photography. The Annual Exhibition was staged at a new venue in 1976—University College School. The popularity of the exhibition ex- ceeded even Council’s expectations, and led to some overcrowding at times. Dr. Sutton gave a talk on the Zaire River Trip, which was staged twice to capacity audiences. Three Junior prizes were awarded. A fuller report of the Exhibition appeared in the February Bulletin. The three AES Groups continue their work. The Exotic Entomology Group membership reached 211 by the end of 1976, and the EEG newsletter maintained its high standard under the editorship of Mr. C. J. Eschbacher, and included some excellent photographic illustrations. The Conservation Group now has 53 members, and Dr. Lonsdale con- tinues to produce an informative newsletter. The Insect Behaviour and Ant Study Group has 20 members, and newsletters have been produced by Mr. M. Parsons. Mr. T. G. Howarth retired as the Society’s representative on the Joint Committee for the Conservation of British Insects. Mr. Howarth has represented the Society on “official bodies” for more than 20 years, and the Council extends its warmest thanks to Mr. Howarth. Our new representative on the JCCBI is Mr. N. H. Cooke, our Treasurer, and a past President of the Society. Mr. J. Roche retired as Hon. Secretary, but remains a member of Council. The Council reports, with much regret, the death of three senior members of the Society: Mr. S. H. Humfrey; Mr. J. A. Robinson and Mr. S. H. Wakely. P. A. Sokoloff Honorary Secretary eo — AES BULLETIN, Vol. 36 103 OF THE TREASURER In presenting the accounts of the Society for the year ending 31 December, 1976, it is once again my pleasure to report that in spite of the prevailing economic climate the Society’s finances have been maintained on a sound basis. Our Income and Expenditure Account produced a surplus of £261, the Publications Trading Account a surplus of £639 and the combined activities of the three AES Study Groups achieved a surplus of £26. By the end of the year the value of the Society’s reserves, measured by the closing balances of the three official Funds, has risen by £1,051 to the impressive amount of £7,767. I hope that with the new classification of items in the Income and Expenditure Account, members will not require a detailed report of the Society’s general financial activities in 1976—which in fact followed much the same pattern as in 1975. However, I must emphasise the mag- nificent increase in subscription income which resulted from the introduc- tion of higher subscription rates coupled with a record increase in renewals covering no less than 86% of the 1975 membership and a continuous influx of new members which averaged nearly 20 per month. At a time of financial uncertainty, this demonstration of support by members has undoubtedly made the Treasurer’s job easier in that the level of essential income has been brought into line with the ever-rising costs of providing essential services such as the Bulletin. I have no doubt that our subscription rates are widely regarded as good value for money. Overall, the Society’s general income from other sources such as donations, advertising and investment income rose satisfactorily, although the surplus on the annual exhibition was not unexpectedly lower due to the change of venue. On the other side of the coin, the Society spent over two-thirds of its total 1976 general income on producing and distributing Bulletins and also incurred the publication of a four-year supply of the 1976 Membership List at a cost of £337. Particularly pleasing was the minimal increase in administrative costs which, in- cluding support grants of £40 to the Study Groups, represented only 14% of total general income. Perhaps the most dramatic financial development lies in the Publica- tions Account with the rise in gross publications turnover from £827 in 1975 to £1,547 in 1976. The cause of this explosion was the publication of the Lepidopterists’ Handbook which sold over 200 copies in the last four months of the year: we have invested nearly £1,500 in the first edition of this title, as the Account shows, with over £600 recovered already in sales revenue we are well on the way to generating new funds to maintain our publications programme in 1977 and beyond. Sales of other titles were extremely buoyant, the Silkmoth Rearer’s Handbook and back numbers of Bulletins prominent among them once again.

Our Balance Sheet shows that we have closed 1976 with liquid assets exceeding £3,200 of which £500 has been earmarked by the Council for additions to the General Fund investments. During the year, the Society spent £102 on office equipment, which constitutes our only type of fixed asset: now that our Secretary has an efficient typewriter and a new system of membership files we have no further capital expenditure to plan for as yet. Looking ahead, I sincerely hope that subscription rates can be held at their present level for another year but this will largely depend on the various factors which influence Bulletin expenditure : —printing costs, advertising content, postal rates, print-order and pagination, to name a few. Administratively, I suspect that in financial terms we will soon have to pay the price of our recent success as an organisation. Members cannot expect the administration of our rapidly growing Society to be shouldered indefinitely by a handful of dedicated (and in my opinion expert) volunteers: outside assistance of some kind will become necessary and will have to be financed either by new sources of income, or restrictions on Bulletin expenditure or by augmenting the slender capital resources of the Society from outside. In this context, may I close this Report by drawing members’ attention to the charitable status of the AES and the corollary that any bequest made by them to the AES would be exempt from capital transfer tax: such a gesture at this moment of time would be of enormous benefit to the Society and therefore to the future of amateur entomology in this country. N. H. Cooke Hon. Treasurer OF THE SOCIETY’S REPRESENTATIVE ON THE JOINT COMMITTEE FOR THE CONSERVATION OF BRITISH INSECTS The Committee met twice in 1976: I attended the March meeting as an observer on behalf of our outgoing representative Mr. Graham Howarth, was appointed his successor in May by Council and duly attended the October meeting in my new official capacity. A select number of rare species, chiefly lepidoptera, continue to concern the Committee: one of them, Thetidia maritima Prout (Essex emerald) has been proposed by the Essex Naturalists’ Trust for inclusion in the schedule of species protected under the Conservation of Wild Plants and Wild Creatures Act 1975. The Committee feel that such a drastic step is premature and have given the Trust some token financial help towards further survey work and I am assured that any AES members will be very welcome in this task. Maculinea arion L. (The Large blue) is of course our only insect already protected under the Act and was reported to be holding out well early in the season at its 108 AUGUST, 1977 one remaining site in Cornwall: the effect of the subsequent drought on the local ant population is as yet unknown but with the crucial nature of this factor identified by Dr. Thomas there is greater long-term optimism being expressed for the future of this butterfly than for some time. Papilio machaon L. (Swallowtail butterfly) has apparently failed to establish itself in any numbers at Wicken Fen after its introduction there from Norfolk stock: however, Gortyna borellii Pierret, a moth new to Britain, is flourishing at a site on the Essex coast under the care of the County Trust, and in Wales a second site has been reported for Eugraphe subrosea Stephens (Rosy marsh moth) which is being kept strictly confidential. Members may like to know that one of their colleagues, Dr. Chelmick, has completed an important survey of dragonflies in Scotland for the Nature Conservancy, which has also maintained its financial support for further survey work on Carterocephalus palaemon Pallas (Chequered skipper butterfly) by the Scottish Wildlife Trust: elsewhere, a rare dragonfly Ceriagrion tenellum de Villo has been introduced into Wood Walton Fen. Only one specific threatened habitat came to the attention of the Committee during the year—Thorne Moors in Yorkshire, where a proposal by the C.E.G.B. to dump fly-ash from Drax power-station was quashed by the local authority aided (I hope) by official protest from the Nature Conservancy, Yorkshire Trust and the Committee. Ironically 1976 had been designated International Wetlands Year but instead we were all far more concerned with the effects of severe drought and it remains to be seen how disastrous the resulting heath fires have been for insects on such well-known reserves as Hartland Moor in Dorset and Thursley Common in Surrey. Relations between entomologists and official bodies were prominent as a topic during 1976. The Committee welcomed proposals submitted by the Forestry Commission to publish a new explanatory leaflet for the benefit of all those who wish to collect insects on Forestry Com- mission land: in view of the widely varying treatment experienced by AES members applying for collecting permits at present, there is an urgent need for a coherent uniform policy to be adopted by the Com- mission’s staff in this respect. Another large official landowning body of interest to naturalists, The National Trust, has been invited to send an observer to J.C.C.B.I. meetings on the same basis as the Forestry Commission. At an international level, the Committee has heard of the establishment of a Lepidoptera Specialist Group within the Survival Service Commission which forms part of the I.U.C.N.; this new group, which includes a strong contingent of British entomologists, is chaired by an American, Dr. Robert Pyle, who will be explaining the work of the Group to the Committee. | | AES BULLETIN, Vol. 36 109 a International trade and investment in rare butterflies has been dis- cussed following the appearance of an article entitled “Why not try a flutter in butterflies?” in the national press and the implications of such articles were reported on by the Committee’s Secretary in a paper submitted to the Council for Nature. At the close of the October meeting, Mr. N. D. Riley announced his retirement from the Committee, thus ending a very long association with its work; he has been succeeded as chairman by Professor Mellanby of the Royal Entomological Society. N. H. Cooke (3266) OF THE EXOTIC ENTOMOLOGY GROUP 1976 was another excellent year for the EEG, and December 1976 saw us with 211 members (161 AES and 50 subscribers). The highlight of the year was the first EEG meeting held at World- wide Butterflies Ltd., Sherbourne, Dorset. About 50 members attended from many distant localities, including Dunblane, Perthshire, Blackpool and Cardiff. All who attended thought the journey worthwhile. Besides the chance to chat with fellow members, there were extremely interesting demonstrations of setting, hand-pairing, printing, close-up photography and a conducted tour of the farm. We were all well pleased with the extra space provided at the AES Exhibition, and 25 new members were enrolled. Four newsletters were published giving a total of about 150 pages of articles by members plus the now well established additional page of photographs. C. J. Eschbacher OF THE INSECT BEHAVIOUR AND ANT STUDY GROUP 1976 proved to be the testing time for the very existence of the IBASG as, due to the pressure of work, the Honorary Secretary, Ken Mardle, was forced to resign his post. To save what I personally con- sidered to be a highly interesting and beneficial group I decided to accept Ken’s offer of its leadership. With my own workload also being heavy, I have had to adopt a slightly new approach to the group’s management, concentrating on producing the Newsletter rather than the more difficult task of co-ordinating meetings. I have therefore defined myself as Editor/Treasurer. Ken handed over to me entirely with our No. 11 issue for March 1976 which was duly distributed to a membership of twenty. There followed a slight lag, again due to the turmoil of the changeover but this resulted in the production of a longer, thirteen page, issue of our No. 12 Newsletter. This included a long and very informative article by Howard Lee called, “How to study Insect Behaviour”. Howard has been most active within the group during 1976 and is at present 110 AUGUST, 1977 co-ordinating members comments and ideas on insect behaviour which we hope will culminate in an A.ES. leaflet on this subject. The format of the group newsletter has changed little since Ken first started its production. It contains the editors introduction followed by various items such as new members, changes of address etc. There is then a large section on members comments and present activities which allows a constant appraisal of the personal work of the members in the field of entomology. This section is then followed by articles dealing with a wide range of topics and finally we have our own wants and exchanges section. Due to a good spirited response at the beginning of 1976 from members who donated as well as submitted their subscriptions, the Group’s past financial difficulties were cleared so that there was an actual profit of Three pounds at the end of the year. The future of the group still holds its promises and the field meetings system that existed in 1975 will hopefully be resumed. We welcome anyone interested in insect behaviour, ecology, breeding etc. We also want to strengthen the Ants side of the group and I will be only too pleased to hear from anyone interested in joining the group who is willing to send in notes or articles on Ant behaviour and Ecology. I hope to increase the frequency of the production of our basically quarterly newsletter so that our members can really keep in touch with each other. Those interested in joining should send an S.A.E. or 60p to me for a years subscription (Address on the inside cover of the Bulletin). Michael Parsons (5432) OF THE CONSERVATION GROUP The system, announced at the 1976 AES a.g.m., whereby the Group’s Committee shares its membership with a separate AES Conservation Committee has been working well: meetings were held in September 1976 and February 1977. A new member of the Committees, Mr. C. Hart has recently been co-opted. I have continued to act as Group Treasurer and I have again prepared accounts for the AES Treasurer. The accounts for 1976 show an increase in the Group’s fund from £59-36 to £80-53 and the reasonably high level of donations over and above the minimum subscription has allowed us to hold that minimum at 35p p.a. The Group’s Bulletin and the reports to successive a.g.m’s of the Society show our determination to help improve the co-ordination be- tween all organisations and individuals involved in insect conservation, but there remains little evidence of progress outside the Group itself. In an attempt to improve liaison with other bodies, the AES Council has ruled that the Society’s Representative on the Joint Committee for the Conservation of British Insects (JCCBI) should be a member of j AES BULLETIN, Vol. 36 | al a Council as well as of our own Conservation Committee. Mr. N. H. Cooke has recently taken over this task following the retirement of Mr. T. G. Howarth who so regularly represented the Society for many years. Despite the problems of general liaison faced by Mr. Cooke, we continue to have good relations with individual organisations. An example of such contact is our correspondence with Mrs. Mary Briggs of the Botanical Society of the British Isles. She drew our attention to a recent conference which that Society organised jointly with the Lin- nean Society at Newcastle University. The subject was ‘Plant/Insect Relations’ and, as it was obviously relevant to our work, a Representa- tive was appointed in the shape of Mr. T. C. Dunn of Chester-le-Street. We also advertised the Conference to all AES members. Mr. Dunn reported that little mention was made of conservation although much interest was shown in our suggestion that amateur naturalists and professional research workers should co-operate more than at present. Representation at an international level has unfortunately been a problem. The ‘Xerces’ conference, mentioned in our 1976 report to the a.g.m., did eventually take place in the U.S.A. last summer and we understand that there was some British representation. We had lost direct contact with the organisers and we could obtain no worthwhile advance information from any source in the U.K. Doubtless we shall hear of the progress made, if any, at this rather obscure event. We continue to produce our bulletin and the present level of produc- tion; two or three issues per year promises to increase as judged by the current flow of news and views from members. We are also sending out copies of “Habitat Digest’ which, for a time, were available to all AES members. Little progress has been made on other information projects such as the proposed insect conservation handbook. The level of interest in local site protection work seems to be on the increase, judging even on the basis of the letters from those members who bother to write in with their news. Our rate of recruitment of members has recently increased, and this is providing a higher propor- tion of keen conservationists, even though the activity of many is short- lived. We have many interesting recent reports on such areas as Bras- side Ponds, Co. Durham; the Empingham Reservoir area in Rutland: the Blackbrook Valley in the Kidderminster area; Abney Park Cemetery in N. London; Tenantry Down, Sussex and Barnes Reservoir in S.W. London. We have held several field meetings since our last report two of which; at Merrist Wood in Surrey and Tenantry Down in Sussex, proved most interesting. In October 1976 a meeting at Abney Park Cemetery, held with members of the London Natural History Society was less interesting (mainly because of poor attendance) but more recently we have partici- pated in two weekend ‘task work’ sessions held by the Sussex Trust for 12 AUGUST, 1977 Nature Conservation at Tenantry Down, and on the first day we made a major contribution to the effort. Our programme of field meetings for 1977 is very promising and I will gladly send details of any meetings which are still to take place after publication of this article to interested AES members. Our stand at the 1976 AES Exhibition was very much field-orientated in that it was based on the practical protection of valuable sites. Much interest was generated by the illustrated examples of what has been done and what can be done. The overall picture seems to be fairly encouraging and, in spite of a temporarily reduced effort on my part, there is every promise that activi- ties are well on the way to a point where our role will become more and more widely acknowledged. D. Lonsdale (4137) OF THE BRITISH BUTTERFLY CONSERVATION SOCIETY In his annual report to the members of the British Butterfly Conserva- tory Society on 5th March, 1977 at the Victory Services Club W.2., the Chairman, John Tatham said that the Society now had a member- ship of 950 and was the largest organisation solely devoted to butterfly conservation in UK. He cited instances where the Society had been able to support objections to planning proposals which had threatened certain well established habitats, with satisfactory results, and also through co-operation with local authorities certain areas had been pre- served as existing habitats or would in due course be designated areas of Habitat Surveys formed the backbone of the Society’s work and records so far received augured well for the future furtherance of the Society’s objectives. Liaison with overseas members and similar organisations had revealed the same problems existed in many countries and the information thus gained and exchanged had been extremely helpful in minimising the destructive effects of modern development. The conservation programme was to be up-dated in the light of the Society’s experience over the last six years and as many members as possible were urged to undertake habitat surveys for a period of five years, if at all possible. The most important factor was not so much the actual butterfly population, but its variation over the years and the causes of the variation; in order to conserve endangered species much more needs to be discovered about the factors that cause these variations, and it was towards this end that the Society’s research would continue. C. J. Tatham, Chairman AES BULLETIN, Vol. 36 113 PARIS INSECT FAIR ee _ The second International Insect Fair of Paris was held in the magnifi- ' cent surroundings of the Palais des Congrés on April 23 and 24. It can _ best be described as similar to our own AES annual exhibition but held | in surroundings like those of a Royal Society soirée. On the first day » one was able to make a leisurely tour round and indeed one had the _ feeling that not many people were there. This was particularly noticeable ' during the lunch hour, taken more seriously on the Continent than it ' sometimes is here. On enquiry in the afternoon we were surprised to learn that there had already been more visitors than to our own exhibition, which, in view of the crush we experience, was a sure indication of the spaciousness of the venue. The Fair was reported on the French radio and the second day experienced a stream of visitors ' by no means all Entomological. Unlike our free show there was an | entrance fee of 75p. The number of exhibits, as opposed to Traders, was very small, but we are pleased to report that the best was British and ' one of our members was involved. This was a joint display put on by _ Dr. Jan Watkinson of Shell Research and Mr. Claud Rivers of the Unit of Invertebrate Virology. It consisted of methods of rearing several _Lepidopteran species on artificial diets and aroused great interest, for | while Continental Europe is strong on taxonomy, rearing is apparently little undertaken by the average amateur Entomologist there. The material on offer was much as can be found at our exhibition but with a great dearth of livestock. There were rather more Coleoptera and Other Orders but the beginner was scarcely catered for at all. The / number of books to be seen was quite pitiful, which surprised us and we | were disappointed not to find the very wide selection of secondhand apparatus and equipment we have every year in England. Nevertheless the new equipment available was extensive and it was interesting to see how it differs from our own. Not a cabinet of storebox to be seen. ' Instead the ubiquitous “Carton”, wellmade, usually with a glass lid _and the old peat “Moll” bottom replaced with modern plastic “Emalen”. | One of the best we saw was called the Teproc box and besides pinned ‘insects it has been so designed that it can be subdivided by smaller | boxes containing carded beetles, minerals etc. _ There were also some magnificent decorative displays of Lepidoptera | of a kind not, so far as I am aware, available in this country. Although lof course not to the entomologists taste, they are popular with the general public and were beautifully prepared with great artistic flair. 'Not un-naturally they were fabulously expensive. There were also some rather fine and inexpensive wall charts of various insects. - One of the chief pleasures of all exhibitions and meetings is the chance to meet with correspondents and renew old friendships in person. In 114 | AUGUST, 1977 this we were amply rewarded and this alone made the all too short trip to Paris worthwhile. Brian O. C. Gardiner (225) LETTERS TO THE EDITOR Dear Sir, I would like to know why we are sent “A code for insect collecting”, when across the country Rothamsted type traps are used which kill everything that enters them. My MV Robinson trap caught between a few and fifty moths a night during March, and its living contents, after recording, were released early each morning into dense cover, whereas one Rothamsted trap I know of, operated by a well-known research establishment, killed more than seventy-five moths a night on several occasions during March. I can produce evidence to back this statement if needed. Yours faithfully, R. A. Bell (5222) BOOK REVIEWS THE WORLD YOU NEVER SEE—INSECT LIFE, by T. Rowland- Entwistle (with Oxford Scientific Films Ltd.). 128 pp. with 280 coloured plates. Published by Hamlyn Publishing Group Ltd. Price £2.95). Oxford Scientific Films Ltd. have established that they are without equal in the filming of the intimate life histories of insects. The use of powerful heat-free lighting systems has enabled the production of very high magnifications of living insects and although specialising in ‘movie’ films, they have also produced still photographs of a very high order for illustration and instructional purposes. This new book includes many of their best pictures, built around a well written and informative text which makes an excellent introduction to the world of insects. It is more than just a book of good pictures and will prove of use to the beginner and to teachers in schools. At the price charged it could usefully be added to the bookshelf of most entomologists. PWC THE WONDERFUL WORLD OF BUTTERFLIES AND MOTHS, by Robert Goodden, pp 96. Royal 4to. Hamlyn Publishing Group Ltd. 1977, Pace £2.95: Our first reaction to this book was “where have we seen it before” and then it struck us. The title page has the same double-page spread of Anthony Bannister's photo of Anthene amarah sitting on some bright AES BULLETIN, Vol. 36 115 I ted flowers as does Paul Smart’s International Butterfly Book! (Reviewed AES Bulletin Vol. 35 p. 127). Apart from this however over half the photographs illustrating this book are by the author and he has clearly taken advantage of his interest in conservation and the importing activi- ties of his firm to obtain photographs of some unusual Lepidoptera. We would cite for instance that of Ants attending the Large blue butter- fly larvae on page 13 and the young Morpho caterpillars on page 61. The book is divided into six chapters which include one each on breeding and conservation. The text, written in Mr. Goodden’s usual breezy style, is there in its own right and is not just a peg on which to hang the photos which, each being accompanied by an adequate legend, can stand on their own. The text is in fact a useful source of information about breeding difficulties and possible foodplants as well as emphasizing biological and not taxonomic information. The coloured photographs are good and well produced colourwise. The size varies and, alas, we have no indication of the magnification. It is our opinion that the full-page ones (remember that this is a large format book) are too large in some cases such as page 79 although that on page 21 of large moths natural size is fine. We particularly like the large double-spread endpapers however. Conversely the photo of the Giant atlas moth is too small. As usual there are a few typographical errors as for instance Utethsia for Utetheisa, Dielephila for Deilephila. We still deplore the habit of bleeding many of the illustrations to the edges and not leaving decent margins. The spate of new colourful books about insects continues unabated. The quality both of the colour reproduction and the accuracy and care taken with the text varies enormously, as does the price. This is one of the better cnes and although a slim volume has packed quite a lot in and is very reasonably priced indeed for a hardback. An ideal present, or for anyone who wants a brief colourfully illustrated account of butterflies and moths. BOCG REVISED CATALOGUE OF THE AFRICAN SPHINGIDAE (LEPI- DOPTERA) WITH DESCRIPTIONS OF THE EAST AFRICAN SPECIES. By R. H. Carcasson, p. 148, 17 Plates, 1976. Small crown 4to. E. W. Classey Ltd., Price £5.80. This is the second edition of the work originally published by the East African Natural History Society in 1968. Unlike Mr. Carcasson’s work on the Swallowtails, reviewed in our previous issue, this one is properly printed and the plates are half-tone, unfortunately not of very good quality, although equal to the original printing but genitalia are included. The usefulness of these illustrations are that they are ol 116 AUGUST, 1977 species which have not previously been figured. The coverage is in fact a revision of the Hawkmoths of the entire Ethiopian faunistic region and should prove to be the standard work of reference for many years to come. It is not however a book for the beginner who will need to use it in conjunction with other works, in particular Seitz, for instance. The experienced enthusiast however, will now be able to differentiate previously confused species and relegate previous doubtful to their true position. The author has, in our opinion very sensibly, continued and amplified the long established practice of basing Sphingid classification on Roths- child and Jordan’s classic work of 1903. He has taken the opportunity of clearing up loose ends such as rejecting Sesiinae as a subfamily name on the very good grounds that these moths are no longer considered to be Sphingids. It should be borne in mind that this is a reprint and conse- quently no account is taken of recent work; by the author; Hodges; Darge; Hayes. Such changes as have been made subsequently however are not major and in no way detract from this book’s usefulness. MJC INSECT AND HISTORY by Prof. J. L. Cloudsley-Thompson. pp. X +242. Weidenfeld and Nicolson, London 1976. Price £8.50. This book is one of the World Naturalist Series and is by a well- known author who has served his subject well and produced a book worthy of a place in the library of any general entomologist, ecologist or interested lay reader. It is a book of horror stories with insects playing the anti-hero’s part. To some extent the discussion is enlarged to cover diseases that while not transmitted, routinely, directly, but perhaps —the point is debateable—indirectly by insects. These include small-pox, scurvy, syphilis and, of course, famine which last can be caused overnight by a Locust swarm. Intriguing points for discussion are raised. Did then the Sinhalese empire in Ceylon collapse because the Tamil invaders introduced Malaria or because their invasions disrupted agriculture and allowed the mossies to breed in the derelict irrigation channels? When the Goths cut the Roman aqueducts in 537 they not only ensured that Christians became the great unwashed but, by cutting and not stopping at source they ensured their army was surrounded, shortly, by a morass, ideal again for mossies and Malaria and indeed it was the destruction of their army by disease that raised the great siege of Rome. The book concentrates on the pestilences rather than the medical entomological aspects and shows on what a knife edge of disaster we teeter. Those of us who express horror at some of the battle statistics quoted in normal history books would do well to ponder even more appalling death lists (not by the way normally quoted in official AES BULLETIN, Vol. 36 117 casuality lists) resulting from typhus, yellow fever and the like. The final chapter also includes commercial insects, the producers of silk, honey, shellac. Thereby showing that insects do indeed have their usefulness, but in no way alleviating the previous intriguing and fascinat- ing story of horror. BOCG THE SECRET LIFE OF INSECTS, by P. Passarin, d’Entréves and M. Zunino. pp. 384; many illustrations and cold plates. Demy 4to. Orbis Publishing, London 1976. Price £8.95. The book is a simple non-technical introduction to various aspects of insect life with some species being examined and illustrated in some detail. Amongst these are Termites, Bees and the Deathshead hawk- moth. The various chapters deal with either an order of insects or else some ecological aspect such as biological control. Many of the photographs are apparently ‘stills’ from film taken especially for a series of television programmes. While many of them are excellent there are some which are certainly out of colour balance (page 29) and others out of focus (top half of page 219). The illustration on page 336 is not only quite hopeless, but quite archaic so far as locust breeding is concerned. However the wide choice given from a long series of cinematograph shots, has meant a number of unusual and otherwise unobtainable aspects of insect life have been able to be selected. We have not for instance come across a photograph of an atropos actually on a honeycomb before. The shot of the Puss-moth’s tails on page 255 is also an unusual one. Besides the colour reproductions there are a number of line diagrams to elucidate points in the text although in some cases they are self- explanatory. In this book they have been particularly well drawn and printed. The title of the book may be rather misleading since the majority of insects are Tropical whereas almost all the insects dealt with here are European and the selection has been of the better known and, to most of us at any rate, more interesting forms. With this in mind the book may be said to come up to expectations and to a reasonably well illustrated account of various aspects for the general reader. This is a foreign book rendered into English but with the same illustrations as the original Italian edition. It was a most agreeable surprise to find that not only have they got the English right. but have spelt the scientific names correctly also, two aspects of printing which have been sadly lacking in some more expensive ‘mid-ocean’ books recently. Full marks to the publishers for the trouble they have on this score. MJC 118 AUGUST, 1977 A GUIDE TO THE INSECTS OF AFRICA by Elliot Pinhey and Jon Loe. pp 36; 13 cold. plates, Hamlyn Publishing Group. 1974. Price (remaindered) 30p. An absolute snip of a bargain not to be missed if obtainable. A very good mix of text, excellently done line diagrams, and coloured plates by Jan Loe, in style and quality equal to those of Gosse. The book forms an excellent introduction to the insects of Africa and our appetite is whetted by the fascinating variety displayed. Would that more of them were readily available for breeding in this country. BOCG THE BIOLOGY OF INSECTS by C. P. Friedlander. pp. 189; line diagrams; 8vo: Hutchinson of London, 1976. Price £4.95. Dr. Friedlander is to be congratulated on producing a fresh approach to this subject illustrated with simple and easy to follow original illustrations. The text shows every sign of being right up to date and one feels that the author has his fingers on the pulse of current research as it progresses. Inevitably, in a subject so vast as that of insects, selectivity has had to be employed and in general the aspects chosen are those not previously considered in many of the major general works available. The text is aimed at those already having some biological knowledge and while designated more for the use of A-level and University courses, the book is of use for all who would wish to know more about the biology— as opposed to the taxonomy and morphology—of insects. Much of the biology of course can be applied generally, but, as it pointed out, many insects do have a specialized biology of their own. Attention is also drawn to gaps in knowledge—something which is very useful in pointing would-be researchers in the right direction. In so many books gasps are either ignored or, reprehensibly, conjectural theory is presented as fact. The book is divided into six chapters. In the first the physiological basis that has made insects such adaptable land animals is explained and dis- cussed. Chapters two and three give a very concise illustrated review of the various orders and their fossil history and development. Chapter four, entitled “Adaptive Radiation’ is an amusingly illustrated account of how insects burrow, run, fly, jump, swim, feed and parasitise. Chapter five gives some account of behaviour and ecology and finally in Chapter six on the economic importance of insects, is discussed not only their control and the mode of action of insecticides, but also the diseases they can transmit and their economic impact. In any book one can usually find errors. In this one we noticed only one mis-spelling, and would, from personal experience, cavil at the statement that Triatoma and Rhodnius cause a very painful jab. They do not. These very minor : AES BULLETIN, Vol. 36 119 ee eee ae re a blemishes are more than made up for by the helpful and selectively annotated bibliographies attached at the end of each chapter. It is a pity however that an otherwise excellent book has been set by non- aligning IBM instead of letterpress. This lack of margin alignment spoils it and is to be deplored. BOCG EXTINCTION OF THE LARGE BLUE SOLVED—A COMMENT We feel that Brian Gardiner’s article on the extinction of the Large blue (Maculinea arion L.), which appeared in the Bulletin in November 1976, needs some qualification. While it may be true that Dr. Thomas has found the cause of the decline of the Large blue from sites which are ungrazed his findings have no bearing on the sites which still have a short turf, plenty of ants and from which the Large blue has also disappeared. In deed the fact that a lack of grazing leads to the disappearance of the Large blue has been known for many years (see for example Oliver 1920, Richardson 1946) and various mechanisms have been put forward to explain this disappearance (Spooner 1963) to which Dr. Thomas has added another. As was originally pointed out in the pages of the Bulletin (Benham 1973) there have been many sites, particularly in the Cotswolds but also elswhere in the Large blue’s range, from which it has disappeared without reason. Many of these sites remain to this day; there are for example several Cotswold sites with very short turf and the right ants as well as coastal sites where turf is kept short by sea spray. Indeed some of the Cotswold sites appear better than the remaining Devon site from the point of view of shortness of turf and presence of ants. We also have to consider the evidence of amateur entomologists who knew the sites when the Large blue was present and on revisiting them today state that they have not changed. Thus there is a real problem in ex- plaining the disappearance of the Large blue from a number of appar- ently suitable sites. This led us to suggest (Muggleton and Benham 1975) that isolation of colonies could by itself account for the disappearance without any other factors operating. The mechanism involved could be genetic, as a result of inbreeding reducing the population’s fitness, or physical, for example very low densities of butterflies meaning that an individual cannot find a mate, or a combination of both genetic and physical factors. Such ideas are not novel and have been discussed at length elsewhere and often in relation to isolated colonies on nature reserves (Hooper 1971, Drury 1974, Diamend and May 1976) while Southwood (1976) suggested that in addition to the Large blue the extinction of a colony of the Checkerspot butterfly (Euphydryas editha Boisduval) in California may also be explained in this way. 120 AUGUST, 1977 The problem is simmed up eloquently by Diamond and May (1976) who, refering to small isolated reserves, say, ‘Consider first the question of immigration. Even if there are many small reserves, a species that is incapable of dispersing from one reserve to another across the intervening sea of unsuitable habitat is doomed to eventual extinction: its lights will wink out one by one, with no chance of re-ignition. The decline of the Large blue in England over the last one hundred years has followed precisely this path. Even fifty years ago it was still a widespread species with many colonies and a more or less continuous distribution from Gloucestershire to Cornwall. Then, as a result of ploughing, lack of grazing and afforestation, the Large blue became extinct at many sites leaving the remainder isolated, since then one by one its lights have winked out and often without apparent cause. In 1963 when the Joint Committee for the Conservation of the Large blue came into existence there were thirteen colonies on the Devon/Cornwall coast, a year later the number of colonies was ten, by 1968 there were only two (Howarth 1973) and both these appear to have become extinct in the early 1970s. Yet this aspect of the problem does not appear to have received suffi- cient attention from those concerned with the conservation of the Large blue. We have been told that as many other plants and animals survive in isolation so can the Large blue. The point that is missed is that the species we find today surviving in isolation are those that have managed to adapt themselves to this situation e.g. there is some evidence that selection has taken place in the Swallowtail butterfly (Papilio machaon L.) resulting in individuals with smaller wings and less powerful flight (Dempster, King and Lakhani 1976). How many species have failed to adapt and fallen by the wayside we can never know. That the Large blue is likely to be one of them seems certain, in which case its extinc- tion in this country is inevitable. With man’s help it may linger on a few more years but its extinction could occur at any time. This raises another problem for, in view of the limited resources available for conservation, it may be argued the effort and money at present being spent on this species (which is after all widespread in Europe) should be switched to other butterflies (or even other insects!) where there is more hope of success. Although it now appears too late to save the Large blue we may per- haps learn from this example and, hopefully, prevent the same fate befalling other species. The species which may need attention are any which have a more or less continuous distribution which is then broken up leaving isolated colonies from which the species begins to disappear without apparent cause. Certain Fritillaries (Argynnis spp.) which are disappearing without any apparent cause from suitable habitats in eastern England (Heath 1974) may be examples of this. As a counter- AES BULLETIN, Vol. 36 121 measure it may be possible to breakdown the isolation by transferring individuals from one colony to another. On theoretical grounds only very small numters need be moved, and this could have been done with the Large blue while there were still several colonies but apparently it was not tried. Alternatively, if suitable sites can be found new colonies could be established nearby and this is now being attempted with the Large blue although in this case it is probably too late to have any effect. Finally, it is important to stress that there is no one reason why the Large blue has declined in this country, a number of factors, some interacting and some which we do not properly understand, have con- tributed to its near extinction. It must also be admitted that on any reasonable basis attempts to conserve it must be judged unsuccessful. What we can hope for is that we will learn from the mistakes of the past, be less willing to accept that there is any one easy solution to problems such as this and ensure that we are better prepared in the future.

AUGUST, 1977 CONSERVATION The articles from the pen of K. J. Willmott (1974; 1975) have created an interesting discussion on the delicate and emotive subjects of conservation and collecting. He seems to have a fanatical dislike of collectors although he does say at one point there “are good types’’ as exampled by a person he dissuaded from collecting a Purple Emperor (A patura iris. L.). One is left wondering when a good type becomes a bad type. Which species represent the borderline? Can one kill a Small white (Pieris rapae L.) or perhaps a White Admiral (Ladoga camilla L.) without being subject to the abuse of Mr. Willmott? The views of collectors have been expressed with good taste and sound reason (Bryan 1976); (Sell 1975) and (Simpson 1975) and there does appear to be good reason to suppose that species will continue to come and go despite collectors and conservationists. The Black-veined white (Aporia crataegi L.) and the Gypsy (Lymantria dispar. L.) have dis- appeared along with other species and all attempts at reintroduction have failed. They no longer find our island a fit place to live. The demise of the Black-veined white is fully recorded by Allan (1948). Other species such as the Comma (Polygonia c-album L.). Golden plusia (Polychrisia moneta Fab.) and Gold spangle (Plusia bractea Schiff.) have arrived or extended their ranges. In Derbyshire and Cheshire there appear to be signs of a slight change in the status of the Large skipper (Ochlodes venata Bremer and Grey), less common and the Small skipper (Thymelicus sylvestris Poda), more common. We cannot hope to conserve everything any more than we would desire to collect everything. On a nature reserve in Derbyshire we have a rare hybrid Orchid and the habitat has been “managed” to protect it. But at what cost? Trefoils, Clover and Birch have been cleared to ensure the survival of the Orchid but the same habitat is shared by many things including a colony of Common Blue (Polyommatus icarus Rott.) butter- flies. What are their prospects? Gardiner (1977) “propounds a heresy” that small birds which feed on caterpillars could be controlled locally to increase butterfly populations. If lepidoptera are what we wish to protect the suggestion is sound, however the ornithological conservationists of Mr. Willmotts ilk would soon be castigating entomologists if this came about. We must remember that our larvae eat the botanists plants and are in turn eaten by the ornithologists birds. A beautiful balance. Nature's balance. Homo sapiens, the supreme predator, has a part to play both as collector and protector but we must be sure of the role. Nobody conserved or collected dinosaurs. Homo sapiens could not interfere as he himself had not evolved, yet they still became extinct. Our efforts in the field of control and protection have not always met with success and in the case of the Large blue (Maculinea arion L.) the AES BULLETIN, Vol. 36 123 eee protection afforded may have been detrimental (Gardiner 1976). Photography is art not science. It can be interpretive and creative but no matter how skilled the photographer certain things are beyond his scope. One wonders if species such as Berger’s clouded yellow (Colias australis. Verity) would have come to notice by photography alone or how the Grey and Dark Dagger (A patele psi/tridens) would be separated not to mention Eupithecia spp. or Procus ssp. Surely only science can unravel these and other mysteries. It is hoped that the passion and abuse between conservationists and collectors can be kept out of a otherwise healthy discussion; after all we all desire the lepidoptera to flourish. A. W.

APRIL 1973 ; The idea for a spring collecting trip to the South of France was first discussed by us at the AES exhibition in the autumn of 1972. Neither of us could find sufficient time for a continental expedition later in the year, and having already seen a number of reports on the interesting butterfly fauna to be found in Var in early spring, we decided to plan a camping holiday in the area at this time. We were joined in this venture by Gillian Taylor and David Richards, who enjoyed the holiday despite our continual entomological enthusiasm. Our journey south from London began on the bright and sunny afternoon of Friday, April 6th, and we soon met with delays in heavy traffic before we reached quieter roads between the newly green hedges. As we drove towards the coast we eagerly anticipated the warmth and rich insect life of Mediterranean France, and speculated on what we would find so early in the year. Sadly, we arrived in Newhaven only in time to see our evening ferry moving steadily away from the quay, and 124 AUGUST, 1977 so after an unplanned extra night in England we boarded the ferry for Dieppe the following morning. The weather continued with bright sunshine and a chill breeze for the crossing, and we continued on to a the following morning we found the grass encrusted white and crunchy with frost, while the pale blue sky promised a fine day to explore Paris. We were able to travel through empty central streets and squares on this Sunday in early spring, with the willows and chestnuts just starting to come into leaf in the parks and beside the Seine. After camping south of Paris at La Genevraye, we continued our journey on the autoroute, the day being enlivened by observation of Black Kites (Milvus migrans, Boddaert) at regular intervals along the banks and fence posts, presum- ably awaiting easy meals from the road. Until we arrived south of Lyon the vegetation was less advanced than in England, but then, surprisingly quickly, pink and white fruit blossom appeared in the orchards beside the Rhone, together with willows fully in leaf. When we arrived at the camp site in Vedeére (near Avignon) the wind was strengthening from the north, and by the time we had finished supper the tents were being battered by violent gusts and squalls. Luckily, an embankment with a group of Scots Pines alongside gave us some shelter from this sudden ‘mistral’. The next morning, Tuesday, 10th April, we were dismayed to see the consequences of the overnight storm. Snow remained in sheltered hollows at the roadside, and covered the slopes of the Montagne du Luberon. It remained cold with snow on the ground from Aix-en- Provence to St. Maximin-la-Ste. Baume, and we wondered how it would be possible to find butterflies in the region within the period of our holiday. However, as we continued east along the N7 towards Vidauban it became milder, and we experienced for the first time on the trip a pattern which was to become familiar during our stay in Var, namely the abrupt local changes in weather and vegetation that occur at this time of the year. In late afternoon we pitched the tents between oleander hedges at Le Pont d’Argens south of Les Arcs, in countryside which looked more green and entomologically promising. The following morning we enjoyed a clear sky and warm sunshine which enabled us to begin collecting. We started in the vicinity of the camp site where the flowers at the edges of the fields and near the River Argens proved attractive to butterflies. We soon saw Macroglossa stellatarum L. buzzing rapidly to and fro between feeding, and we also saw Colias crocea Geoff. and Polygonia c-album L. We caught Antho- caris cardamines L., Aricia agestis Schiff. (the only record for the trip), Carcharodus alceae Esp., Celastrina argiolus L., Euchloe ausonia Hb., Lycaena phlaeas L., Pieris brassicae L., P. napi L., and P. rapae L.; a total of eleven species of butterfly for our first locality. We then moved on to a streamside area about 8 km south of Vidauban on the D48, where we were able to add seven species to the day’s butterfly list. AES BULLETIN, Vol. 36 25 These were Callophrys rubi L. (which in one spot had the habit of successively appearing from the same position behind a bush as if being released by an unknown benefactor), Gonepteryx cleopatra L., Inachis io L., Iphiclides podalirius L., a single fine fresh individual, Nymphalis antiopa L., worn but still magnificent in flight, Vanessa cardui L. (the sole record during our holiday) and finally Zerynthia polyxena cassandra Hb. We were pleased to find this last species, one of the main objectives of our trip, but disappointed not to find Callophrys avis Chapman in what appeared to be a suitable locality, with plenty of Arbutus unedo L. shrubs which are the foodplant of this species. Two kilometres further south we came to a wooded area which had been destroyed by fire some years previously, possibly in the widespread fire which originated at Cap Bénat in 1965. There were noticeably fewer butterflies flying in this area, so re-colonization had not been completed despite good vegetation regeneration. We managed to find a few large larvae of Melitaea cinxia L., an interesting find as we were to see the adults flying in two localities less than a week later. Our total of nineteen species of butterfly (including the M. cinxia larvae) on our first day collecting was much better than we had imagined could be possible after the weather we had experienced 50 km to the west the previous day. A spring speciality of Var we particularly wanted to find was Erebia epistygne Hb. and we decided to try a locality mentioned by Shaw (1970), the area beside the Montferrat-Comps road (N555) a few hundred yards north of the Bargemon turn. On the morning of 12th April we stopped atop a ridge about 3 km north of Les Arcs, en route for the E. epistygne locality. To the north were wide views of distant snow crested peaks under a pale blue sky, and despite a stiff breeze we soon found good numbers of Philotes baton Bergstrasser flying close to the ground amongst the dry grass stems and small olive bushes. A little further north and on lower ground, conditions were more sheltered and we obtained permission to collect on the land of a small farm. This procedure excited the many farm dogs and amused the farmer greatly —after we had departed from his house we could hear his laughter as he told a friend of his strange English visitors looking for butterflies. Here we added Lasiommata megera L. to our list for the trip, together with Coenomympha pamphilus L., and a single Tomares ballus Fab. was captured by I.F.G.M. after a joint search alongside the road follow- ing a brief sighting as the butterfly took off from amongst the dry grass. Despite a further intensive search on the hillside among abandoned terraces and small olive trees, we were unable to find any more individ- uals of this local species. We then continued through Draguignan to the E. epistygne locality and arrived in the “Zone Militaire’ (which covers a large area of this region) for lunch. There were notices along- side the road stating that access to the area was absolutely forbidden, 126 AUGUST, 1977 but nevertheless we walked along the roadside looking for this species, which is the only spring Erebia. However, we were evidently too early on this occasion (possibly due to the recent cold weather) and we did not see any butterflies flying over the stony ground in windy conditions. Therefore, we continued northwards to the Grand Canyon du Verdon, a spectacular limestone gorge where the road twists between the edge of the sheer cliffs and the broad limestone hills. There was snow at the roadside at the west end of the Canyon, and the freezing wind rattled dried leaves on the small beech trees, a wintry contrast to the spring flowers at Les Arcs. That night, and throughout our stay at Les Arcs, the clear sky allowed temperatures to fall rapidly after sunset, so the warmth of a tent heated by stove and gas lamp was very welcome. The next day, Friday 13th April, was very hot and sunny, and we decided to investigate the valley of the River Argens further downstream at Le Muy. This proved to be a rich collecting ground in a beautiful setting, with white fruit blossom set against the vivid red earth, and with a forested background on the steep slopes beside the river. A line of nettle tress (Celtis australis L.) were only just starting to come into leaf, but we soon found the Nettle tree butterfly (Libythea celtis, Laicharting) settled with outspread wings on the branches, occasionally taking off for rapid flights around the trees. Despite having come through the period of winter hibernation many were in good condition, though the irregular outline of the wings made this difficult to check without capturing the butterfly. We also took Anthocaris belia euphenoides Staud., though only the golden males were found at this time. The hibernated vanessids, Nymphalis antiopa L. and Nymphalis polychloros L. were both rather worn, but still flying with power and agility, and frequently capable of avoiding capture. One large Tortoiseshell made a splendid sight sunning itself with wings flattened against the warm earth, the colours still bright and fresh, belying its age. A_ single Scolitantides orion Pallas was captured by Gillian but did not appear for I.F.G.M. or C.D.W.-S. Other species taken for the first time were Pararge aegeria aegeria L., Vanessa atalanta L., Leptidea sinapis L., and Pyrgus malvae L. The Z. polyxena cassandra were fiying in good numbers, and as previously observed they appeared to prefer riverside situations. In the afternoon we drove south to Ste. Maxime, and then leaving the hazy blue of the Mediterranean behind us we turned inland to Collobriérs, where a brief inspection showed nothing of entomological interest. We therefore moved on to the Forét du Dom where we un- successfully searched the strawberry trees for the larvae of Charaxes jasius L. As we returned northwards in the early evening the forested hills behind us were evenly shaded in paler and paler tints of blue-grey in bJurred outline against the distant reddening haze. The following morning we returned to the locality 3 km north of AES BULLETIN, Vol. 36 AT Les Arcs where we had taken the single T. ballus two days before. Although the weather was sunny we were unable to find more, and so we carried on northwards to the Old Grasse Road from Draguignan. Here there are excellent collecting areas amongst the abandoned terraces and ancient olive groves. Here we saw M. stellatarum again, and found for the first time Clossiana dia L., Colias australis Verity, Erynnis tages L., Glaucopsyche alexis Poda and adult M. cinxia. In addition we found L. sinapis again, though we did not find the closely related L. duponcheli Staud. here or elsewhere on this holiday. In the afternoon increasing cloud made collecting unprofitable, and so we decided to explore the country to the west of Draguignan around Salernes. We returned to Les Arcs via L’Abbaye du Thoronet, which during our visit was isolated in sunshine against a dark and stormy sky. On Sunday 15th April we decided to explore more intensively the valley of the River Argans downstream from Les Arcs. We parked close to a bridge across the river about 5 km south-east from Les Arcs, and spent the day walking eastwards through woods and meadows beside the river before returning to the car by a more northerly route. In hot and sunny weather we saw good numbers of butterflies, the N. antiopa and N. polychloros making a splendid exhibition flying strongly over the narrow meadows and fields. We saw Papilio machaon L. for the first time, and also noted /. podalirius, Z. polyxena cassandra, L. sinapis, L. celtis, and S. orion, plus most of the species seen previously near the camp site at Les Arcs and in the meadows at Le Muy. The next day, Monday 16th April, we drove through Fréjus and St. Raphael to a valley about 2 km north of Agay. The warmth and sun- shine resulted in very enjoyable collecting over rough, stony hillsides beside a stream, the air heavy with the scent of herbs. We soon found Glaucopsyche melanops Boisduval and Spialia sertorius Hoffmannsegg, but we did not see Zerynthia rumina L. in what appeared to be a very suitable locality, only taking Z. polyxena cassandra again. A single Euphydryas aurinia Rottenburg of the bright form provincialis was taken, but we were probably a little early for this species to find more. Our final day collecting in Var, 17th April, began well with C.D.W.-S. taking a single P. mannii Mayer near the camp site at Les Arcs, the only one taken during our holiday despite inspection of all the “small whites” seen. We planned to reach the Mt. Ventoux area by evening, so we decided to stop at the various sites we had previously inspected to the north of Les Arcs. The weather was as good as on the previous two days, providing ideal conditions for collecting butterflies. We stopped first at the ridge 3 km north of Les Arcs, and on this occasion C.D.W.-S. was able to capture a single T. ballus. Moving on to the New Grasse Road from Draguignan the only female A. belia euphenoides of the trip was obtained, together with C. alceae, G. alexis, G. melanops, L. 128 AUGUST, 1977 celtis, N. polychloros, §. orion and most of the other species seen pre- viously in this area. We then continued on to the Montferrat-Comps road where in the fine weather conditions we soon found a strong colony of FE. epistygne within the area of the military camp. We were able to secure both males and females in fine condition, though despite an apparently lazy flight they were surprisingly difficult to capture. The only other species found in the area was C. dia, the locality being still without flowers at this time of the year. It is interesting to speculate why E. epistygne should have evolved away from the later flight periods of other Erebia species. Possibly the early flight period enables the larvae of this southern species to exploit the food plants when they are in a greener condition before they dry off in the heat of summer. Our collecting in Var having been successfully concluded, the remainder of the journey was continued uneventfully to a camp site at Vinsobres, approximately 20 km north-west of Mt. Ventoux. Thus ended our collecting in Var, with only Gonepteryx rhamni L. new to our list on the 18th April when we explored the valley to the north of Mt. Ventoux. We also found C. rubi, the commonest and most widespread species we encountered, together with P. baton and E. tages. The area seemed to be some time away from a good flight of spring butterflies, and we spent the next day exploring the region, including a drive above the snowline on Mt. Ventoux. We resumed the long journey north on Friday 20th April, and before reaching Grenoble we passed through a brief but heavy snowstorm on the Col de la Croix Haute which cleared suddenly to reveal snow covered hills to the north-east. We continued on to camp at Annecy where there was further snow overnight. The next day we drove through Switzerland via Geneva and Jura in sunshine and showers. The warmth and butterflies of Var seemed very distant as we passed through the Jura, clad in deep snow, towards Dijon. After taking two days to cover the remainder of the journey across northern France, we arrived back in London on Monday 23rd April. On a very enjoyable holiday we found a total of 42 species of butterfly (listed below with localities). This was less than we had hoped for after the results of de Worms (1966—S0 species) and Shaw (1970—S1 species) but it was apparent that the season was later then experienced by these collectors, probably being similar to that experienced by Bretherton who obtained 42 species in 1962. For example, we did not see C. avis, which had evidently not yet emerged, while C. rubi remained fresh until the end of our stay. It is interesting to note that Nabokov (1931) found many of the species we encountered in Var a month or more earlier in the Pyrénées Oriétales (Le Boulou), probably earlier than most would emerge in Var. From our own observations, and the paper by McLeod (1972), the Mt. Ventoux area appears to be later than Var, so collecting AES BULLETIN, Vol. 36 1Z9 expeditions for spring butterflies to these areas should be planned accordingly. I. F. G. McLean (3848) C. D.

MAY 1976 My previous visits to Provence in the company of W. L. Coleridge and my father, the late H. J. Cribb, over ten years ago, had always been in late June and July, giving no opportunity to see those insects which are on the wing in early spring and produce only one generation. How- ever this year I was able to remedy this in the company of Messrs. L. Christie, D. Marshall, Paul Whicher and R. Uffen. We used my Commer Wanderer camping van and a four-man ridge tent for transit and accom- modation and left at 4 p.m. on the 29th April via Ramsgate Hoverport for Calais. This journey takes only 35 minutes and, despite the French clocks being an hour ahead of ours, we spent the first night sleeping on the edge of a copse west of St. Quentin. We did not linger on the way south, camping in the town site at Bourg-en-Bresse and then driving through Grenoble on the new motorway to stop on the Col de la Croix Haute where the flowery meadows of my memory were just emerging from the snow, some of which still lay in piles on the slopes. Just north of Sisteron we stopped for our first reconnoitre. At the roadside the slopes were dry and stony with grassy patches and clumps of Broom (Cyfisus sp.) and there I found a newly emerged male Anthocharis belia euphen- oides Stdgr., the Dawn of Provence as the French call it. Several large day-flying geometrid moths were on the wing which I first took to be a form of Wood Tiger as their flight, size and colour were similar. These later laid long strings of eggs in the pill-box. The moth is Fidonia pennigeraria Hiibn. I then disturbed a brown butterfly from the grass which when netted turned out to be Erebia epistygne Hubn., the earliest of the Erebia family. The Broom was alive with Green-Hairstreaks, Callophrys rubi L., which was to be the commonest butterfly seen on the trip as it occurred wherever we stopped from south to north France. 132 AUGUST, 1977 The sun was very hot and we drove on to Digne along the edge of the River Bleone. Since I was last here the town has grown to almost double the size, spreading westwards along the Bleone but happily not up into the valleys of the mountains behind the town. Unfortunately there are now restrictions on the collecting of lepidoptera in the domain of Digne which covers the mountains and valleys around the town and we decided to drive out on the road towards Entrages to just beyond the prohibited zone and camped in a small valley beside a stream where a spring issued from a hole in the rocks. There is a pass rising from here called La Clappe which leads eventually to Barreme on the way to Grasse. We drove up the pass but found that little was yet out due to the altitude and confirmed that our collecting should be restricted to the lower ground. Our camping routine had now established itself and while Dave Marshall and I slept in the van, Laurie Christie, Paul Whicher and Raymond Uffen shared the tent. We had brought all our food with us apart from bread and wine and had a light breakfast each day, bread and cheese for dinner and in the evening I cooked a meat meal with ‘mash’ or rice. In woodland camps we used open fires but on camp sites one needs Calor gas or similar means of heating. The weather was being very kind with very hot days but slight night frosts which made our extra blankets most welcome. The next morning was spent exploring the valley round the camp. Dave and I managed to catch two large green lizards, Lacerta viridis, a male and a female. Having found where the lizard basked and where its bolt hole was, the method was to return quietly when the lizard was again out sunning itself, place the butterfly net in the mouth of the bolt hole and then disturb the lizard which ended up in the net. We netted a male Aglia tau L., flying along the roadway—it is a beautiful Saturnid moth and the males fly fast in the sunlight in search of females. We also found a female Emperor, Saturna pavonia L., which we kept with us for several days and despite her calling every evening she did not assemble one male and died unmated a week later. Several Large tortoiseshells, Nymphalis polychlo- ros L., were visiting the Prunus bushes which were in full flower but all netted were bedraggled males. The Blues were present in large numbers, the commonest being Glaucopsyche melanops Bdu., a species I had not taken previously. It was flying with G. alexis Poda. (=cyllarus Rott.), the latter being distinguished from it by the blue dusting at the base of the underside wings. Present also were Cupido minimus Fuessl., our Small blue, and the Common blue, Polyommatus icarus Rott. All were in perfect condition. As the sun reached into the valley we found both Leptidea sinapis L., the Wood White, and its very local cousin L. duponcheli Stdgr. I found the latter mated on a flower head but was unable to keep the female alive long enough to obtain ova. Both these species seem fragile in captivity and succumb fairly soon in the confines of a pill-box. Along the roadside and around the camp we found AES BULLETIN, Vol. 36 133 = Meee eee ae ee ee en Sree asunNNas anscr-wrcoseassne 134 AUGUST, 1977 webs of the Black-veined white, Aporia crataegi L. on the Hawthorn and Sloe bushes. Many had small larvae still present while others were empty and we found larvae in various stages on the stems feeding and one pupa already formed. Later many of the larvae produced both dip- terous and hymenopterous parasites. With the restrictions for collecting operating in the area, despite it only applying to the lepidoptera, we decided that we should move else- where and on the Monday morning after breaking camp we drove down to Digne for bread and the post office and then took the road north towards La Jarvie. We stopped about 10 km out of Digne to collect on some dry slopes adjoining the road. Here we saw Iphiclides podalirius L., the Scarce swallowtail, and several Genepteryx cleopatra L., the beautiful Southern brimstone. I took another specimen of E. epistygne and one E. triarius de Prun. just emerged. In this area the lavender fields had again been replaced by cereal crops and one would expect that the attraction of past years having gone, there would be a greater dispersal of butterflies. Certainly the numbers seen were not great. Here I also found Euchloe ausonia Hubn., just emerged, which I first mistook for a female Orange tip, Anthocaris cardamines L. which were now flying everywhere we stopped. We drove on beyond the village up into the high land beyond but only to find that the season was late and little was on the wing. I netted several specimens of the Pale clouded yellow, Colias australis Vty., quartering the ground above its food plant, Hippo- crepis comosa L., and we took a female which subsequently laid a large number of eggs on sprigs of the vetch placed in a pill-box. I also took a few male Adonis blue, Lysandra bellargus Rott., which had just emerged. An assessment of the possibilities made us decide to retrace our steps and we drove back via Digne and took the road south towards Castellane. That evening we camped on a downside north of Castellane near to a stream and spent the evening trying to dig out Field Crickets, which filled the air with a noisy chorus. Each night at every camp we made on the trip we were sung to sleep, or kept awake, by a chorus of Nightingales and woken each morning by the Cuckoo. Each evening the small burrowing owl, Scops Owl, called monotonously from dusk until we fell asleep—it has a mournful short-hoot repeated every few seconds. Next morning we stopped in the town square of Castellane, dominated by a towering rock on which is perched a large church. Here we re- stocked with water and bread and then took the road leading into the Gorges de Verdon, one of the spectacular rifts in the Provencal Alps. We stopped for lunch short of the entrance to the Gorge and collected alongside slopes. Raymond got his nose buried in some Artemesia sp. which harboured species of case bearing moths while the rest clambered about on the slopes which fell down to a wide river leading from the great artificial lake above Castellane. Erebia triarius was quite common AES BULLETIN, Vol. 36 135 — and on a damp patch there were the Provencal form of Euphydryas aurinia Rott., the Marsh fritillary, Melitaea phoebe Schiff., and a lot of C. australis. Of interest to Laurie were the large numbers of Ascala- phus species buzzing about over the slopes. These neuropterons hunt flies on the wing and we found them commonly all over the areas we visited, the females commencing to emerge during our second week. The larvae look rather like larval ant-lions but roam freely in search of prey. Entering the Gorge we stopped at the path leading up to a Tibetan monastery to photograph the Gorge and some of the orchids growing in the woodland. By the roadside Dave took our first specimen of Zerinthia rumina L., a species which I had not seen in the wild before. We also netted a female Camberwell beauty, Nymphalis antiopa L. This area appeared to be rich in plant and insect life but we had decided to press on to an area south of the Gorge which looked from the map to be very wild terrain. However as we came into the area we found that it was a vast military zone with plenty of ‘Defense d’entrer’ notices along the road and with much military activity going on. We were forced to drive on until we came to the edge of the enclosed area just north west of the village of Bargemon where we found a small valley with a natural camp site beneath some oaks. The valley on both slopes was wooded with scrub through which were the old paths used for timber extraction. I found a spring lower down which came up out of a tumble of limestone rocks. This was to be our headquarters for the next three days. Where we built our camp fire there was a large horse mushroom which we had next morning for breakfast with bacon— Paul refused to partake and expected to find us all dead before the day was out. On the slopes we again found Z. rumina, all males, and after some diligent searching found the food plant, Aristolochia rotunda, an insignificant plant with the ‘pipes’ almost black. Laurie had discovered that the small quarry near the road was alive with Scorpions which lived in the crevices of the quarry face. He and Paul spent a morning collecting them, perfecting a technique which included picking up the scorpion from behind by gripping the ‘sting’ between finger and thumb. Specimens for setting were killed with boiling water and then dried and stored in the ‘fridge’. It was rather like dealing with lobsters. In the scrub I disturbed a male and female Black Cock and several snakes. We netted several Large tortoiseshells and another Camberwell beauty female. I placed the two antiopa we had now taken into a pill-box and put them into the ‘fridge’ where they went into a state of torpor. Later when we had returned home I sleeved these onto a sallow, (S. caprea) in my garden and they laid their characteristic rings of eggs around the twigs. We also captured several female C. dia L. which laid eggs on the walls of the pill-box and not on the violet leaves provided for them. We needed to go down to Bargemon for bread and wine and Dave and I took the van down in the morning, stopping on our way back by 136 AUGUST, 1977 the roadside just outside of the village. Along the roadside there were large groups of a yellow cruciferous plant Biscutella laevigata which were continually being visited by A. belia euphenoides, very brilliant males and the more subdued females. We netted several and then dis- covered their little orange eggs laid on the flower buds, small larvae and on one plant almost full fed ones. They are not unlike the larvae of the Bath white, Pontia daplidice L., for which I first mistook them as there ~ were several females of that species flying along the roadside. Unfortu- nately the larvae, like those of our Orange Tip, are cannibals and although here, and later, we collected a lot of the eggs and larvae, I ended up with only nine full-fed larvae. The larvae in captivity ate the garden crucifer, Lunaria, Honesty, feeding on the young seed pods. The pupae simulate the pod a wild pea, Lathyrus sp., and are variable in colour. The stony banks were smothered in clumps of Soapwort, Saponaria occymoides, and this was attracting both Humming bird hawkmoths, Macroglossum stellatarum, L. Broad-bordered bee hawks, Hemaris fucifcrmis L. Back at the camp, there had been a lady visitor, a wife of one of the officers at the camp, and a helicopter had been making a ‘reccy’. During the afternoon we took a few males of rumina on the valley slopes and also took two male Z. polyxena, Schiff. estab- lishing that both species fly together over part of their range. On the following day we broke camp and drove down via Bargemon to Seillans where on a previous trip I had found the lavender fields to be very rich in insect life. Today the village is hardly recognisable. It has soread out all over the slopes, eating up the lavender fields and old olive groves. We Crove through the village and out towards Mons along a narrow winding road only to find that this had also been en- croached upon, housing on one side and on the other the continuing military presence. Eventually we came upon open meadow land near the road junction to Fayence where we had lunch and did some explor- ing. A few butterflies were moving across against the breeze, mostly Pierids, and I netted a fresh female Small copper, Lycaena phlaeas L. Laurie discovered some interesting black earwigs under the rocks while searching for scorpions but after lunch we moved down into Fayence. Above Fayence we stopped where in a previous stay in this town I had found a wealth of insect life in some deserted small holdings. Several of these now had new houses erected in them and others had been cultivated but some of the slopes above the town were still quite wild, although new tracks into the area indicated that they might not be so for long. In the hot afternoon sunshine Scarce swallowtails were soaring along the slopes and I netted several together with a female P. machaon L. She later obligingly laid me 76 eggs on a spray of Fennel inside a large plastic box. I disturbed another male Z. rumina but was unable to find its foodplant although I searched the slopes. In one of the meadows, beside an irrigation canal, several fritillaries were flying. 37 1 236 Vol AES BULLETIN, 138 AUGUST, 1977 These proved to be the Marsh fritillary, again of the light coloured Provencal form. Devil’s-bit scabious, Succisa pratensis, was growing in abundance there, confirming that this was their food-plant. It is a form very close to the Spanish beckeri H-S. race but in Spain I found the food-plant to be Honeysuckle. I took a female but it failed to lay eggs. However I was able to keep it alive until my return to England where it successfully paired with one of my Cumberland males. The results will be of some interest as she immediately laid a batch of eggs. Most of the species met with on our travels were flying here. The slopes were dotted with Spartium junceum coming into flower and splashes of crim- son of the Judas tree, Cercis siliquastrum, just going over. Despite the changes this was still an interesting and delightful spot. I disturbed two Golden Orioles from an oak tree and we found signs of a badger at work. i In Fayence a market was in full swing and we had a wander round while Paul telephoned home to give an account of our progress. The town has also spread down towards the airfield so that it has lost its imposing domination of the plain. Rough walls along the streets which used to house groups of geckos had been pointed and tidied up but Oleanders and exotic Agaves still overhung the roadway. After doing some basic shopping we drove south out of the town taking the road towards Frejus and as we approached the village of St. Paul-en- F6ret we noticed a ‘camping site’ sign, one of our lucky breaks. The site hugs the edge of old terraced slopes which have been invaded by secondary mixed woodland with a very open canopy of Pinus pinaster. We met the owner and pitched camp beneath the pines, appearing to be the sole campers present. The shop, swimming pool, etc. were closed as the season had not yet started but we were able to get a ‘gaz’ refill as open fires were not permitted. We were to spend the next five days here and could not have chosen a more exciting spot. Swallowtails and G. cleopatra were regularly passing through the camp and euphenoides was laying eggs along the side of the camp path. We found Aristolochia rotunda growing all round the edge of the camp and subsequently took further male specimens of Z. rumina. The orchids growing here were also very exciting and Dave and I found a group of huge Lizard orchids beside one of the deserted farmsteads at the top of the slope above the camp. As yet we had not been able to establish what the foodplant being used by G. cleopatra could be as none of the shrubs looked like Rhamnus spp. However Raymond had observed females visiting a dwarf shrub with small serrated leaves and this turned out to be Rhamnus alaternus. We picked a few shoots and placed them in with some females in a small breeding cage I had brought with me and they immediately started to lay their eggs on the underside of the leaf tips. We obtained about 36 eggs when a sudden gust of wind blew the cage over and the butterflies all escaped. Laurie had taken some good Buprestid beetles in oe AES BULLETIN, Vol. 36 139 ——— SS SI a a a ea A ar vivid scarlet and green colours, on flowers around the tent and I took a specimen of Trichodes alvearius, a beetle which is known to live inside bee colonies, both wild and domesticated. This is an area rich in apiaries and we saw many large ones on the hillsides where thyme and wild lavender carpet the slopes. After a day here exploring the vicinity of the camp we had added several new species to our tally. The most interesting was the Nettle-tree butterfly, Lybithea celtis Fuess.; near the Camp we had observed a moth-like insect fluttering around a tree which was not yet in leaf. The tree had a smooth bark and the pointed buds which where starting to unfold looked rather like Elm leaves. The insect was crawling about on the tips of the twigs and we were able to identify it as L. celtis and therefore assumed that the tree was Celtis australis. | shinned up the tree which was about twenty feet high and was able to find several eggs which were laid on the leaf shoots or just below them. They were small and brownish and quite hard to find. These we gathered unfortunately hatched during our journeyings and although offered nettle and elm leaves they failed to eat and died. Later I learned that a friend back in England had a nettle-tree in his garden waiting for them. A Blue which was just beginning to appear was Philotes baton Bgstr., about the size of our Small blue and marked with black in the white fringes and heavily spotted on the underside. On the following day we made a sortee down towards Frejus. Just beyond St. Paul we found a rocky sandy area where a lot of ant-lion (Myrmeleonfidae) larvae had their funnel-like pits. We dug a few out—they are sand-coloured and very difficult to see in the sand—and I have one in my green-house at the moment still catching ants that happen to drop in on him. The larva flicks sand up with the head to knock the ant down as he tries to clamber out. This area was rich in Orchids, the most spectacular being Serapias vomeracea, which grew at the roadside. This area is the start of the maquis scrub land and the garigue, low growing scented scrub, which stretches on down to the Mediterranean. Tree heaths and Strawberry trees, (Arbutus unedo), form thickets which are quite hard to penetrate. We hoped to see Callophrys avis Chapman, which feeds on Arbutus and Charaxes jasius L. which does likewise but we were not lucky. I think we were too early for the latter in view of the lateness of the season. We crossed a high pass leading towards Frejus and stopped at the top where the slopes were thick with white lilies and several species of Orabanche, one a bright primrose yellow. Z. rumina was taken by Raymond and there were hundreds of Ascalaphids quartering the slopes. This area is worthy of further exploration but after our lunch of bread and cheese we drove down through another military area to Frejus. It was very hot and we did not linger but took the road out leading over a high mountain pass towards the Esterel massif. Unfortunately a high wind was now sweeping across the 140 AUGUST, 1977 garigue and our stops to examine the heath-covered slopes yielded little but Green hairstreaks and wandering G. cleopatra. In the afternoon we took the road which cut inland across the Nice-Cannes motor way to stop by the new Lake of St. Cassien which replaces the old Frejus barrage. This lake is used for boating, finshing, etc. and the road runs along its edge and then crosses over it near the northern end. We stopped to search the slopes above the lake and found several larvae of A. crataegi on the Hawthorns which were just coming into fiower. These also were attracting Rose chafers, Cetonia sp., and several species of Diptera. Gn one, quite near the van, I noticed a web of larvae feeding and assumed them to be one of the Lasiocampid moths which we were finding quite commonly on the Hawthorns but closer inspection dis- covered them to be the larvae of the Large tortoisesheil, VV. polychloros. I was not aware that Hawthorn, (Crataegus monogyna), was one of its foodplants. The finding of this web incited us to start looking for others and when we got. back to our camp that evening Laurie found two larvae on some pear suckers beside the entrance to the camp. I guessed that these must be larvae which had fallen from a nearby tree and we walked up to the entrance after our evening meal and there on the wild Pear (Pyrus sp.) were five separate webs of the larvae ranging from newly hatched to almost full grown. I climbed up to shake the largest down like ripe pears and we came back to the camp laden. Next morning I was explaining to the camp proprietor what we had been up to and he showed me a cherry tree in his garden which had been defoliated by larvae. I asked him where they were and he said ‘je les ecrase toujours’. I asked if I could examine his fruit orchard and with Dave’s help I managed to take several more webs of larvae on his Cherry trees. The problem of feeding such a horde of larvae was eased by their obvious acceptance of a wide range of trees and during the rest of the trip they ate Hawthorn, Cherry, Pear, Sallow and Elm but those I kept produced rather small pupae and imagines. The first pupated on the 18th May and emerged on the 3rd June. Several died in trying to pupate and two produced hymenopterous parasites (single cocoons) in the second larval instar. No other parasites occured amongst my larvae and at the time of writing I am trying to keep the imagines alive to pair next spring by feeding them up and then keeping in a refrigerator over the winter. That night a steady rain started to fall and this continued throughout the night and all next day so that we spent our time sorting out material and yarning in the caravan. In the evening we dressed up in our waterproofs and ventured out to do some stone turning in search of beetles, scorpions and anything else of interest. Laurie discovered an earwig-like insect which lives in leaf litter under stones, a member of the Order Embioptera. The insect makes a silken tube inside which it hides. The following day the rain cleared and we had another hot day ————— EP EEE SE LE AR AES BULLETIN, Vol. 36 141 to do a little more collecting in the terrain around the camp. We found that the rain had completely obliterated the ant-lion pits but in captivity I later observed that when rain threatened (even with the cage inside my greenhouse) the larva obliterated its own pit by agitating the sand. David took a newly male Limenitis reducta Stdgr., sunning itself outside the tent. We were allowing ourselves a fairly leisurely return north to arrive there on the Saturday 15th May and that afternoon we drove back via Fayence and Mons through beautiful mountain roads edged with Cowslips and Blackthorn in flower to the Col de Valferriere where we met the Grasse-Digne road. By evening we had reached our previous camp site outside Digne and spent the night there. Next morning we spent a couple of hours along the valley and roadside where I was able to take one or two more L. duponcheli. Laurie was searching some of the willows above the stream in the hopes of finding larval webs of N. antiopa and did find two small webs of larvae near their old egg batches but these later turned out to be N. polychloros, adding a further foodplant to the list. N. antiopa was quite common here now and we watched one crawling about the leaves of a large Poplar but I think she was in search of ‘honey dew’ rather than laying her eggs. We had decided to go back via Gap instead of over the Col de la Croix Haute and found the road fairly easy and much less interesting than our southward journey. We stopped short of Gap to examine some downland near the road and here I found a lot of Adonis blues flying, including some females, and two L. duponcheli males flying with L. sinapis. The bushes had been defoliated by a small moth larva, in particular the Sloes. Unfortunately Raymond lost a camera fitting but after some searching he found it and we moved on through Gap to pitch camp in another deserted camp site above the town. The facilities were a little spartan but clean. The site is looking west towards the massif of Les Ecrins, permanently snow-capped, where lies the Meije and the village of La Grave, another happy hunting ground. The next morning we drove a short distance up the side road leading from the camp and spent an hour in some flowery meadows there beside an irrigation stream. A lot of insects were on the wing and I added the Mazarine blue, Cyanirus semiargus Rott., and our first Mellicta, M. parthenoides Kef., to my tally. The slopes were thick with Horseshoe vetch and the usual Adonis blues and C. australis. Clossiana dia was flitting along the edge of a wood in which Paul had found large clumps of Lady Orchids. This was quite a delightful spot but we had to press on and drove up the Col de Bayard towards Camps. On the border of the Department of Isére we stopped by the side of a vast rocky slope where we spotted some dark brown butterflies on the wing. The slopes were alive with butterflies and we took Erebia triarius and Lasiommata petropolitana Fab., the Northern wall. Wood whites were 142 AUGUST, 1977 everywhere and we spent an hour or so scrambling on the rocky mountain-side. There was a lot of Sedum growing amongst the rocks and Dave found an almost full-fed larva of the Apollo, Parnassius apollo L., sunning itself on the rock beside its foodplant. While I was setting up to take a photograph of it Dave said “There is a snake about a foot to the left of you” and there was a small viper, with its colour exactly matching the brownish soil, lying just below the larva. We tried to catch it but it disappeared into a crack below a rock. In captivity the larva fed on shoots of the Sedum eating the lower leaves first so that the eatings were not apparent on casual observation. For me the point of interest was the colour of the larva. The ground colour is black with bright yellow spots along the spiracle line which coincides with the colour of the other Alpine races with which I am familiar. In comparison the larvae from Jugoslavia and Spain all have reddish- orange spots of a slightly different pattern and I feel that there may possibly be two species of Apollo. By a river where there were clumps of Willows we stopped for a brief while and took some Duke of Burgundy fritillaries by the road- side. Laurie discovered that the trees and bushes were covered with newly emerged Cockchafers, Melolontha melolontha L. We collected a lot of these up as he wanted specimens and could have taken hundreds had we wanted to. That night we camped again at the municipal camp at Bourg-en-Bresse and on the 13th May we drove north via Seurre to Dijon. We stopped just north of the town above the airport where there were some downland mea- dows and a coppiced wood, part of the Plateau of Langres. The woodland was thick with Cow-wheat, Solomon’s Seal and Lilies of the Valley. I took the Duke of Burgundy and Erebia medusa Schiff, while on the downland there were E. aurinia, E. tages, C. euphrosyne and dozens of C. australis. Paul found Monkey orchids and crosses between it and the Lady orchid and some small Fly orchids and by the road there were several webs of Aglais urticae L. on a nettle bed. Later on this area would probably be alive with both downland and woodland species. In the afternoon we drove on via Chatillon, Troyes, Sezanne and Chateau Thierry to camp in a wood just south of Villars Cotterets. This was a delightful spot, a clearing in a wood which I found up a long bumpy drive. Again orchids were common and we added the photographs of some very large Bird’s Nest orchids to our score. The soil was chalky and the wood dropped down to a swampy area thick with Sallows; Dave and I had a search for Purple Emperor larvae, Apatura iris L., which occurs all over this area but with no luck. In the early hours of the next morning I disturbed a group of locals who were gathering snails in the swampy area. Several times on the trip we observed people at this activity. We were now nearing the day of departure and after breakfast we drove to Pierrefonds where we stopped for victuals and to admire AES BULLETIN, Vol. 36 143 the castle and then on through the forests of Compiegne and Retz towards Amiens. We stopped for our lunch near Montdidier and ex- plored a swampy area in which was a large decoy pond which had been cut out of the peat. It was full of bream and I saw a small pike. Several Grass-snakes were sunning along the banks and I had a very good view of a Coypu which surfaced a few feet away from me. However the whole area was devoid of butterflies other than the Wall, L. megera L., and contrasted sadly with the richness that we had left behind us in the south. As we drove on towards Calais, via Boulogne, we passed through the vast wheat fields again where spraying of selective weedkillers was in full swing, filling the air with the familiar sickly smell. That night we spent in the municipal camp site at Calais. We arrived about 7 p.m. to find all services shut, even the wash-house. The site has a lot of permanent French-owned caravans on it and the space for genuine travellers is limited. It was still deserted of staff when we left next morning to drive to the Hoverport on the far side of the town. In a town which depends a lot on cross-channel voyagers the camp site is certainly not to be recommended and is no credit to the Burghers. At the Hoverport we had a little time to spare and wandered over the surrounding sand dunes where signs of rabbits were every- where. On the scrubby bushes of Sea buckthorn, Hippophae rhamnoides, we found dozens of webs of the Browntail moth, Euproctis chrysorrhoea L. Our trip back across the channel was as smooth as a bus ride and the journey back through Kent and Surrey was uneventful. It must be considered to have been a very interesting and rewarding trip. The cost per head worked out to be about £53 which covered everything except wear and tear on the vehicle. From leaving Bourg until nearing Boulogne we had been worried by a rhythmic drumming of the front near wheel and changed the wheel as the tyre appeared to _ have developed a bulge. Subsequently I found that a large hole had formed on the inside of the tubeless tyre, probably occasioned by hitting a kerb or rock when in the south. As it could have burst at any time on our return journey we could have had a sticky end on some of those hairpin bends on the way back. Otherwise the vehicle behaved splendidly and averaged about 24 miles to a gallon of petrol. Arrangements for travel and insurance, etc. were made through the Camping Club of Great Britain of which I am a member, using their Carefree Holiday | service. P. W. Cribb (2270) 144 AUGUST, 1977 GUARDIANS OF THE ALDER KITTEN On the 15th of June, 1976 with the sky cloudy and the mercury destined not to fall below 17 degrees Centigrade, I set out on a quest for Harpyia bicuspis using light. My wife unusually not being able to accompany me, and bugging friends on holiday, I was on my own. On arrival at the chosen locality, with the Honda generator strapped to a wheeled shopping carrier and all other paraphernalia in both hands or crushing me in a rucksack, off I staggered into the dusk. A quarter of a mile and almost there. The only audible sound being my own muttering regarding previously questioned sanity and the swishing of long grass against shoes. It was a beautiful evening. Suddenly a great crashing of branches in the wood made fear add to the perspiration already stream- ing down my face. It could only be my arch enemies—the heifers. Now I don’t dislike young cows but they always seem to sense my unease and take full advantage—after which I usually end up climbing a tree. But not this time, oh no. Not even the entire herd, all now loosening up in the wood, would deter me from the hunt for Alder Kitten. Definitely not. Abandoning previous thoughts of a relatively open site for the light, and rounding a woody corner, I was confronted by a huge snorting and dribbling Minotaur. The load was shed in an instant, the Honda dropped, and I fled. Allowing ten minutes for It to despair of finding me, a short search yielded the equipment and I set up with my back to a large climbable Birch tree-—being situated in a box canyon composed of both this species of tree and Alder. The 250 watt bulb struck and heaving a sigh of relief I started drinking hot coffee from a surprisingly unbroken thermos flask. After a half hour it began to look good. A twelve foot column cf insects were dancing and whirling around the mercury vapour bulb. Just checking moths on the sheet became almost impossible due to the numbers encountered—with many kinds of different insects paying a call. A wasp appeared, sheared both sets of wings from a Crane fly and made off with the still struggling body—ignoring the ultra-violet light. Midges whined in the ear, a couple of moths rum- maged down my shirt, a beetle up a trouser leg—if bicuspis doesn’t turn up tonight.... Another crash from the woods brought me back, and then they arrived— 20 heifers in a steady stream surrounding the light. At this instant, amidst pictured scenes reminiscent of Custer’s last stand, I saw a male Alder Kitten sitting tightly and composed on the outskirts of the sheet. Quickly boxing the little beauty I returned to the defence of the apparatus—waving a walking stick and shouting (as all good farmers do) “Gayup”. In reaction to this appalling display of bad manners two bolted, one relieved herself, and the rest closed in. Re- doubling my windmill like efforts saw little change and after noting the position of yet another Alder Kitten, I risked a full blooded charge AES BULLETIN, Vol. 36 145 at my now raised hind quarters and boxed it. Nevertheless, they were getting bored with their madman baiting and after looking back with a baleful eye, slowly wandered away. Four more bicuspis came to the light before midnight when a retreat was beaten in absolute darkness. But these guardians of the Alder Kitten had the last laugh. It was only on reaching the safety of the car that I _ discovered that my foot had found one of their trademarks—intermit- _ tently left like silent landmines on the dry pasture, ready for the fool with the light. Colin Pratt NOTES ON THE REARING OF OAK AND NORTHERN EGGAR On the night of 25/26th July, 1975 while on holiday, I took a some- what worn Oak Eggar (Lasiocampa quercus L.) at the MV light trap of Rear Admiral Torlesse in the New Forest. I brought the moth home with me to Oxford and on July 28th and 29th she laid a total of twenty-one light brown eggs loose in a cardboard shoe box. She died on August Ist having laid no more eggs. One egg was lost, the other twenty were kept in my unheated room and hatched on August 12th. It was very warm both inside and out at this time last year. The young larvae ate a small piece of the egg shell to enable them to emerge, then _ wandered away from the egg in search of vegetable matter. I kept them in plastic boxes and fed them on fresh hawthorn leaves which they | took to and ate with no problems. The first ecdysis occured on August 23-24th. On August 26th the larvae were photographed by AES member Tony Leech, by which time the larvae were 1.7 cm + 0.1 cm. One larvae moulted for the second time on September 6th, the rest between September 10th-12th. They were placed outside in kilner jars in an old rabbit hutch on Septem- ber 14th and were then ranging in length from 2.5 - 2.8 cm. On September 27th, 1975 at the AES exhibition I purchased ten Northern Eggar (Lasiocampa quercus callunae Palmer) from a dealer. These larvae were at approximately the same stage as mine although a couple were slightly larger. I discovered that they had been received as ova at the end of July from an entomologist in the North of England and that soon after they had hatched they had been sleeved outside and were now feeding on privet although some had been kept on other foodplants. These larvae were placed in a kilner jar and joined mine outside in the rabbit hutch. From October Ist I changed them from hawthorn onto privet, for the | first couple of days giving them both foodplants, then solely privet. They _ appeared to have no problems adjusting and from the first day the privet ‘leaves were eaten. I changed the type of foodplant for three reasons. (1) by this time of year the hawthorn leaves on the bushes were becoming ge a a et a a ae 146 AUGUST, 1977 old and tough and looked very unappetising for young larva. (2) I knew that the larvae would be liable to continue feeding after the hawthorn leaves had fallen, to awake during the winter and possibly require food and to cease hibernation in about March, long before any wild hawthorn leaves would be available; whereas privet leaves would be on the bushes more or less all through the winter in some form. (3) I wished to com- pare the progress of the two types of larvae under as similar conditions as possible so I kept them all together in the rabbit hutch, the ten Northeners in one kilner jar and the twenty other Eggars divided equally into two jars, and have them all feeding on the same foodplant. I shall now deal with the progress of the Oak eggars first, and then the Northern eggars for comparison. The first of the young Oak eggar larvae completed the third ecdysis on October I1th and by October 18th all twenty had done so. At the end of October the larvae were transferred to cylinder cages containing cut privet sprigs standing in jars of gravel and water with the water level just up to the surface of the gravel.—so that the sprigs have ample water without running the risk of the larvae crawling down the stems and drowning. Down one side of the cage I stood a sheet of corrugated cardboard almost the height of the cage and bent round so that it covered just under half the inside wall of the cages. During November the larvae began to eat less and less and become more sluggish. I kept the foodplant to a minimum. The larvae tended to rest stretched out along the main stems of the foodplant and after a couple of days when no food plant had been touched and some of the larvae had moved onto the card, I clipped the leaves of the twigs to get rid of any material which might develop mould. I left the bare twigs standing in the jar in the cage with the larvae roosting on them. To my surprise, over the next couple of days the larvae all crawled down off the twigs and behind the corrugated cardboard into the dark, aligning themselves along the grooves. This behaviour makes good sense since it would be unwise to attempt to spend the winter in such an exposed position on leafless twigs both because of predators and the greater exposure to harsh weather. Whatever the cause of this behaviour it was very suitable from my point of view for I could now leave the single piece of card out with all the larvae roosting on it and clean the cage with minimum disturbance. Thus hibernation was commenced in clean cages around November 20th. I kept a sprig of privet provided and renewed at intervals just in case a hungry larva woke up, but the best policy is to insure that the larvae are kept sufficiently cool so that they hibernate steadily till the first signs of spring. My larvae began their first nibbles on February 18th, 1976 and were eating privet well on warm days at the end of February and in March. The 4th ecdysis occurred between April 15th-22nd and the Jarvae AES BULLETIN, Vol. 36 147 assumed their second colour phase and pattern. In the previous instars they were bluish with a yellow, black and white marking on each seg- ment. Now they had acquired tawny or golden fur with blue black between the segments, and no dorsal white markings along the back. The larvae were photographed for the second time on May Ist and on May Ilth averaged 6-5 cm long. The fifth ecdysis occurred between May 18th to 24th. The maximum length attained in most cases was 8.0 cm =+ 0.1 cm, after which the larva tends to shrink slightly and feed less. The first cocoon was spun on June 12th, 6 cocoons were spun by June 22nd, 18 by June 29th and the last was spun on July 6th. The hard brown cocoons contain larval hairs and, like the larvae, should be handled with care as they may cause irritation. I usually took the pre- caution of wearing rubber gloves when dealing with the larvae and avoided suffering any such complaints. The cocoons were spun up amongst the leaves and stems of the foodplant. The first male emerged on July 13th, followed by 2 females on July 16th. Emergences continued until July 3lst by which time 8 males and 12 females had successfully emerged. After a number of specimens had been taken for my collection 3 males and 2 females were placed in a large netting cage on July 21st when a successful mating occurred. The first eggs were laid on July 22nd and hatched on August 10th. These ova were kept in a thick stone-walled outhouse somewhat cooler than last year’s which may account for the fact that they took 19 days to hatch as opposed to 15 days in 1975. I was rather busy that summer and observed no pairings, but can say that the pairing period is fairly brief. I found that the adult moths, which do not feed, lived up to 2 weeks though a great deal depends on the temperature at which they are kept and their activity. The larval skin when shed at ecdysis is burst along the side of what corresponds to the larval thorax by a dramatic swelling (especially noticeable in young larvae) of that area, and the larvae emerges to leave the old head capsule generally attached to the old skin, which is not eaten. At the present time I am following the young larvae of the second generation through. My treatment of the Northern eggars followed exactly the same plan. These larvae were just over 3 cm long by the middle of November and began hibernation at the same time. They seemed to be exactly like the Oak eggars in every way except for being slightly darker in colour. Then on January Ist (1976) a rather surprising event occurred. The largest of the ten Northen eggars moulted and assumed his equivalent of the second colour phase I mentioned earlier, only much darker over- all, a deep sooty chocolate brown. He nibbled a privet leaf or two and then went back into hibernation. This was the first ecdysis shown by any of the larvae in this batch of Northern eggars since I obtained them. I recorded the maximum and minimum temperature each day 148 AUGUST, 1977 over the winter but at present can see no apparent cause that this was a temperature effect. The larvae all resumed feeding in the second half of February. One larvae fell behind and died on March 17th. Between April 15th and 22nd the rest of the larvae moulted and assumed the second pattern of coloration and marking, although not as dark as the larva that moulted in January. On May Ist these larvae were photographed and on May Ilth measured 4 cm + 0.1 cm except for the largest which measured 6.5 cm. Between May 18th and 24th ecdysis occurred again (in which the very dark larva changed into a lighter livery like the others) and the final ecdysis took place from June 17th. On June 23rd I went on holiday for a month while Tony Leech and my mother looked after and recorded the progress of my livestock. ! returned on July 21st to find all nine surviving Northern eggar larvae still feeding. Then strange things began to happen. On July 22/23 a first cocoon was spun up amongst the privet leaves. On the 24th a naked pupa was formed on the base of the cage. On August 7th a third larva spun a partial cocoon but then crawled out on the 9th August and pupated in the open on August 13th. On August 25th a fourth larva spun a cocoon and pupated successfully. Between July 22nd and August 27th two full grown larvae shrank and became stumpy and together with a third died for no apparent reason. By August 27th I had 2 naked pupae and 3 normal cocoons containing pupae. One larvae was still feeding well and con- tinued to do so until finally spun up without any problems on October 17th. At the time of writing, October 28th, all pupae are alive but no imagines have emerged. They remain in the outhouse and will probably now hibernate to emerge next year. I hope to have details of any emergences included in a subsequent Bulletin. From my observation while rearing this batch of Northern eggars alongside Oak eggars in similar conditions I would like to comment on three points. (1) The life cycle of the Northern eggars seems to take significantly longer than the Oak eggar, even when both are reared under similar conditions, although I realise the limitation of drawing conclusions from such a small sample of larvae. Since the Northern larvae were about two months old and had been sleeved outside, before I obtained them, it is possible that they may have been preconditioned in some way. (2) I have heard of several descriptions of different dark colour phases in Northern form larvae. Perhaps some factor such as tempera- ture at ecdysis may influence the darkness of the colour phase shown from one instar to another, or possibly the change observed in the larva that moulted on January Ist resulted from some metabolic change that had occurred for hibernation. AES BULLETIN, Vol. 36 149 LS (3) I wonder if there is some overall reason for the rather upset behaviour of the Northern eggars when pupating. Since I had no such problems with the Oak eggars kept in a similar conditions it would seem this was dependent on the Northerners themselves and I wonder if they were waiting for some environmental effect not present in an environment which suited the others. It has been suggested to me that over the generations Northern eggars may have become entrained to Northern conditions and adopt a two year lifecycle in response. Rearing them in Southern conditions seems to have mixed them up, perhaps a physiological clock was telling them one set of information and the information received from the environment conflicted with this, the effects being those described above. P. Waring (4220) 1977—THE YEAR OF THE PUG—PART | It seems that, comparatively speaking, few lepidopterists devote a great deal of time and attention to the fascinating group of just over 50 species comprised in the sub-family Eupitheciinae, nopularly known as the ‘Pugs’. Over 100 years ago the illustrious Reverend H. Harpur Crewe, of Suffolk, set us all a shining example by collecting, studying and breeding practically every then known British species of this group —not to mention discovering some new ones—but in the subsequent and current literature I can find no comparable example. This group of pretty little moths always fascinated me, so it was with a considerable degree of astonishment that, on looking through my own records for the past 46 years, I discovered that I only ever seem to have bred about 17 of them! So I have decided to remedy this lament- able omission by making 1977 ‘The Year of the Pug’ and seeing what I can do to breed out as many species as possible, especially those I have not bred before, and to interest others in doing the same, comparing notes with them and with anyone else interested in the project. One of the great advantages of choosing this group for such a project is the possibility of discovering a species new to Britain. Moths of such diminutive proportions tend to be overlooked; furthermore, many members of this group look superficially alike and are thus easily confused. Even if one does not discover a new species, there is still a great deal to be discovered about the life histories. The early stages of even some of the commoner species are still imperfectly-known, and I strongly suspect that it is the exceedingly small size of the larvae, tending to render them all but invisible even when assiduously searched for, which has been the main factor limiting our knowledge of their larval habits. The disadvantages of this group are that the adults are very ‘fiddly’ to set: however, to counterbalance this, a representative reference collec- 150 AUGUST, 1977 tion of the group does not take up much cabinet or storebox space. The eggs of these diminutive moths, being little bigger than pin-points, are consequently difficult to spot in the wild; and their larvae, scarcely more than animated slender threads, have a habit of escaping from the breeding-cage, or getting overlooked when cleaning out the cage and being thrown away with the discarded foodplant. However, by using smaller cages and smaller quantities of foodplant at one time, one can control this situation better; I shall put forward some suggestions on this point in a subsequent article. Last year I found that numbers of females of this group came to my trap and, what is more, laid eggs in the egg-packing cartons (after all, that is what they are: for!) In fact I have found that quite a few females of other groups also visit the trap, so the common assertion that ‘practically only males come to light’ is a myth! I will certainly admit that generally more males than females come to light, but after some of the results I had last year, I am already beginning to wonder! According to my records, 10 different ‘Pugs’ visited my trap in Northampton last year; these were Eupithecia centaureata Schiff. (Lime- speck Pug), E. castigata Hb. (Grey Pug), E. togata Hb. (Cloaked Pug), E. coronata Hb. (V-pug), E. subnotata Hb. (Plain Pug), E. nanata Hb. (Narrow-winged Pug), E. subfulvata Haw. (Tawny-speckled Pug), E. pumilata Hb. (Double-striped Pug), E. exiguata Hb. (Mottled Pug) and E. absinthiata Clerck (Wormwood Pug). Of these, E. centaureata was by far the most frequent visitor, with E. castigata a close second, followed by E. absinthiata in third place. Of these 10 species, 5 produced ova, viz., E. centaureata, E. castigata, E. absinthiata, E. togata and E. coronata. Of these I bred the first four species, while the last-named laid a small batch of eggs which infuriating- ly failed to hatch. I suggest that those who run a trap breed from ova laid by females which come to light (believe me, you will get them) and in addition of course keep a weather eye open out in the field for all the early stages as well as the adults. Those who do not run a trap had better redouble their efforts in the field to make up for missing out on the much easier way of breeding by simply cutting out batches of ova from the egg-packing cartons! To ascertain the species, what I do is to check the catch for that particular night in my trap records; this, of course, obviously limits the identity of the ova to only those species which occurred among the catch. Supposing there are, say, three species: I then look up these three species in South’s ‘Caterpillars of the British Moths’ Book 2 and check the descriptions of the ova, which usually enables me to make a positive identification. Even if only one species has turned up, it is still a good idea to check the description of the eggs in this book, as certain other small moths, such as Sterrha species, also lay very small eggs. Once one is reasonably sure of the identity AES BULLETIN, Vol. 36 151 of the ova, a suitable choice of foodplant to offer the larvae on hatching can then be made. I have frequently also found gravid females on walls, palings and fences, even in town; so do as I do and always be prepared by having one or two small pill boxes or other suitable containers at hand at all times. Boxes for this group need be so small that two or three will fit into an unobtrusive corner of a coat or jacket pocket, or a lady’s handbag. The only thing then you may have to worry about is the frequently peculiar looks you get from passers-by as you box the moths. In the case of children, they will often ask you ‘what you want that for’ —and you have a golden opportunity of starting some young person off on entomology! In my next article I will list a number of commonly-encountered _ ‘Pugs’ with brief descriptions -of their ova and larvae, a selection of _ alternative foodplants, and for the benefit of those who do not run a _ trap I will also append some notes on the most likely habitats for finding _ both the imago and the early stages of the species described. A subse- _ quent article will deal with the less common species, or the commoner species but whose early stages are little-known, with some ideas on how we can see what we can do to find out more about them. | | S. J. Patel (751) _ HYBRID HAWK-MOTHS In response to Mr. Adam’s report in a recent Bulletin, we also had an | unexpected pairing during May 1976. We were breeding from about 100 Eyed hawk (Smerinthus ocellata L.) and 60 Poplar hawk (Laothoe populi L.) in the hope of obtaining hybrids between these two species. We were also breeding from a small number of Lime hawks (Mimas _tiliae L.) which were mostly female, and were most surprised to find a male Eyed in cop with a female Lime, when inspecting the breeding cages one evening. Unfortunately they had parted by the next morning, so the following evening we placed two male Eyes in a cage with a female Eyed and the same Lime hawk. Again a male Eyed paired with the female Lime, and they had parted by the morning. We repeated the procedure the following evening but this time decided to watch them, | not long after midnight they parted following a great deal of convulsive movement and beating of wings by the female Lime hawk. She then deposited her first ovum shortly after parting, and a total of eight were ‘laid over a period of five nights. As expected they all proved to be infertile. Our success with hybrids between Eyed and Poplar hawks was much greater and fertile ova were obtained from three pairings between female Psplar and male Eyed hawks (hybridus Steph.) and two pairings between male Poplar and female Eyed hawkes (inversa Tutt.). Of the a Ke as oe | SESS eS 152 AUGUST, 1977 hybridus ova approximately 65, 40, and 5 respectively were deposited by the three female Poplar hawks. In all cases the parents parted before dark, and there was a great deal of convulsive movement and beating of wings by the females. In the third case in particular the femal’s desire to part was so great, that when the male came into contact with the side of the cage and clung on firmly, she tore herself free rupturing herself in the process. Although this female was able to deposit five ova that evening, by the following night leaking haemolymph had coagulated and she was unable to deposit any more. As Mr. Adam’s reports, the activity of the females when releasing from hybrid pairings does appear to be much greater than that observed in normal pairings, although our experience does not suggest that these are necessarily infertile. Of the 110 hybridus ova, 94 emerged successfully, 75 were reared to the pupa stage, and 70 had emerged as adults by the end of August 1976. Some of the more interesting observations were as follows: (a) In the first instar the young larvae were very similar to Poplar hawk larvae. In later stages it was very easy to distinguish between them, the first stripe nearest the head being similar in colour and density to the next five stripes, whereas in the case of Poplar larvae the first stripe is much more clearly defined (see, for example, South). (b) The pupae all had strong male characteristics, the tubercles being slightly more prominent than in male Poplar pupae. (c) The adults had a wide range of spot sizes on the rear wings ranging from a smudge to quite clear blue/purple spots, with the brown markings of the Poplar as usual above the spots. The markings on the forewings generally followed that of the Poplar and in six cases they were very pretty being tinged with pink. This may have been inherited from either of the parents, since a number of Poplars have emerged from the same series also with pink wings. Returning now to the inversa ova, we have not, as yet, had any success in breeding these beyond the first instar. There are a variety of reasons given for lack of success in breeding this hybrid, some of which claim that it is only rarely fertile. whilst most state that the reason is the smaller size of the Eyed ova. The ova obtained from three pairings in 1975 and 1976 were nearly all fertile although the larvae rarely emerged unaided. These were known to be fertile since the red horn (also characteristic of young Eyed larvae) was clearly visible through the shells of the ova, as was its head with the mouth opening and closing at irregular intervals. Two of the larvae emerged unaided, possibly from the first ova deposited which, it is claimed in various literature, are larger than those deposited later. Unfortunately they died before the first moult, apparently from some sort of internal blockage. A number of larvae were assisted to escape from the eggshell or were released by cutting it open with a | | | 4 oo. — a <= ~ — —
