Alexander, visited the Island about 12 years ago, and for the past 3 years has come with our friend, Mr. Walter Harrison, the botanist, in order to check up the Tipulidae. Some of the best times I have had have been their visits and our collecting trips, and the fact that Doctor Alexander has shown such an interest and written everything connected with that family, gives it the stamp of authority. Dr. A. E. Brower of the Maine Forest Service has shown great interest in the work and has contributed many records taken through his breeding experiments on the parasitic hymenoptera and has also furnished many records of other species as well as material. Being an expert lepidopterist, the material in that order has had the advantage of his work in collecting and also determining species, which accounts for its being such a well-represented group. He is indicated in the text by (Br.). Mr. C. A. Frost, Honorary Curator of Coleoptera, New England Society of Natural History, has shown his usual interest in promoting anything that has to do with entomology, and no matter what I have asked him, or when it was asked, he has been most kind in determining species. I give him my hearty thanks. To the New England Society of Natural History I am in- debted for the loan of books, and to their librarian. Miss Mary B. Cobb, who has the true understanding that a library should THE MOUNT DESERT REGION 13 be alive, and not a mere collection of books. To the same society, I am indebted for the pictnre of Mr. Johnson. To Mrs. William Qnimby, for the exacting task of typing the manuscript. With the exception of those mentioned above, no individual or institution has had anything whatsoever to do with this publication, and I feel obliged to make this statement because after Mr. Johnson passed on, certain individuals made state- ments of friendship and gave the impression that they had helped in his work, whereas, the facts were quite the opposite. 14 BIOLOGICAL SURVEY OF THE ISLAND OF MOUNT DESERT "An island full of hills and dells, All rumpled and uneven With green recesses, sudden swells, And odorous valleys driven So deep and straight, that always there The wind is cradled to soft air." Elizabeth Barret Broavnixg Situated on the southern edge of the Boreal region, and the northern line of what is known as the Transitional Zone of the Austral, where the species of the so-called Canadian Ufe-zone meet those from the South, the Island of Mt. Desert furnishes a most fascinating place for the naturalist to study the insect life. A central range of mountains rising from 1000 to 1500 feet forms the backbone of the Island from east to west, with steep cliffs toward the east, more moderate ones toward the west, and to the north and south, gentle slopes which leave a section of a third of the island with an altitude of about 200 feet above sea level in each direction. This mountain range was cut by the rivers and the ice of the glacial period, which gouged out the great U-shaped valleys of today, and also formed the basins which are now the lakes and the fjord called Somes Sound. The mountains toward the east are polished off and have a vegetation of scrub on the bare granite, while the western mountains are heavily wooded. In a few words, by studying the geology we find that the lowlands are developed on the rocks of the early Paleozoic and the mountains are the hard Devonian granites, while the great valleys and the lakes result from the glacial action. The other features are due to the earth movement, wind, frost, and the ever erroding action of the beating waves. Now all of this has no direct bearing upon the insects of today, for the altitude of the mountains is practically elimi- nated as a factor by the sea, winds, and fogs, but it has a direct bearing upon the flora, and the flora and insect life are merged and interdependent. I can best give an idea of the flora of the Island by re- quoting from Part I of the Survey. THE MOUNT DESERT REGION 15 Jordan Pond A Glacial Boulder 16 BIOLOGICAL SURVEY OF ''One ^ of the most marked characteristics of tlie island flora is its not only strongly northern, bnt arctic character. On its coast, enveloped in cold fogs and washed by waters chilled by the arctic cnrrents, it is no wonder that arctic plants like Montia foniana and Stellana humifusa should find a congenial home. Moreover this character of the flora is shown by the fact that with one exception, Lycopodium selago, the mountain plants descend to the sea level. Neither on the one hand is the altitude of the mountain summits sufficient to develop an alpine flora nor on the other hand is the warmth and general character of the lowlands sufficient to bring many of the plants of the middle temperate region thus far up the coast of Maine. The flora then may be said to be essentially Canadian, having close relations with the very similar flora of New Brunswick. It also shows, apart from its maritime character, many points of resemblance to the general flora of the White Mountain region. It is in its special problems how- ever, that plant distribution becomes of great interest at Mount Desert." *"A preliminary catalogue of the plants growing on Mount Desert," by Edward L. Rand and John H. Eedfield, p. 20. Cambridge, 1894. THE MOUNT DESERT REGION 17 Prof. M, L, Fernald,^ in referring to the diversity of the island flora, says: ''The flora of the Mount Desert region is not by any means entirely arctic or subarctic. There we find essentially all of the common plants of the Canadian zone and mingling with them in sheltered nooks and meadows or on warm slopes, many scores of plants which reach their extreme northern or northeastern limit on Mount Desert or the immediate coast — such plants as the Pitch Pine, Piniis rigida; the Bear Oak, Qucrcus ilicifolia; the Sweet Pepper- bush, Clef lira alnifolia; the Swamp Loosestrife, Decodon ver- ticillatus; the Meadow Beauty, RJiexia virginica, and the maple-leaved Viburnum, Viburnum acerifoliiwi. This extraor- dinary accumulation within one small area of the typical plants of the arctic realm, of the Canadian Zone and in many cases of the southern coastal plain, cannot be duplicated at any point known to the writer." This diversity and the temperature of the Island are aptly pointed out by Mr. Barrington Moore,^ editor of Ecology, who says : "From the forestry point of view I can state that on no area of this size have I seen growing together forests representing such different conditions and consequently with such different requirements. The vegetation in general ap- pears to be even more remarkable than the forests. Rand has found on the Island 230 species of plants common to the arctic. The crowberry (Empetruni nigrum) grows here at sea level, while inland at this latitude and even further north it is found only on the summits of the high mountains above timber line under truly arctic alpine conditions, and still the southern sweet fern {Myrica asplenifolia) grows here in actual contact with these boreal plants. ''An indication of the comparative mildness of the Mt. Desert climate in spite of its arctic flora, is to be found in a group of Japanese pines growing at one of the gateways north of the village of Bar Harbor, a tree so sensitive to cold that it is killed at the latitude of New York, which yet has ""An Acadian plant sanctuary."

The Maine Naturalist, vol. 1, p. 100, 1921. 18 BIOLOGICAL SURVEY OF lived on this island for twenty years withont protection in winter." In the remarks by Eand and Redfield on the plant distribu- tion you will notice that an exception is made of the maritime flora, otherwise there is a '' resemblance to the general flora of the White Mountain region." This is, to a large degree, equally true of the insects. The same trees and plants of the two places have the same insect enemies, and these insects in turn serve as hosts for the same parasites. The elevations of the island are not sufficient for the arctic-alpine forms of Mount Washington and the boreal species are more com- monly found near the shores and in the vicinity of the lakes, cold spring runs, and bogs, the more sheltered and southern exposures probably harboring the greater number of austral species. In regard to the distribution of aquatic insects, as pointed out by Dr. R. H. Howe, Jr.,^ cold bogs and ponds that are spring fed have less extremes in temperature than ponds that are not thus supplied with water. Thus he found boreal and austral dragon flies living together in the same pond far be- yond their normal limits of distribution. The pond in ques- tion had a bottom temperature of 51°F. in summer and 36°F. in winter — a range of only 15°. The distribution of most of the maritime insects is governed comparatively little by the corresponding vegetation, although the two frequently show a similar distribution. Tempera- ture and a suitable environment are the principal factors. A low muddy shore with considerable marsh and pools of brackish water has an insect fauna of its own, and it is these species that often show^ a very wide distribution. To the proximity of the ocean wdth its modifying etfect on the climate is apparently due this extension of southern species far beyond their normal habitat. On the other hand, cold currents produce conditions favorable to boreal species. The effect of the ocean on temperature is perhaps best shown at *"Tlie distribution of New England Odonata. " Proe. Boston Soc. Nat. Hist., vol. 36, p. 110, 1921. THE MOUNT DESERT REGION 19 Sable Island." "A study of the temperature will show that there are no extremes of heat or cold on the island; that the highest temperature during the past four years was 78° and the lowest point reached by the thermometer during the same period was 5° above zero." View on Great Heath View on Great Heath I am prompted to quote the paragraph above for the reason that the island has a great number of wet depressions found where glacial action has been the dominating formative agent. ^ " Sable Island with a caLalogue of its vascular plants,' Proc. Boston Soe. Nat. Hist., vol. 36, p. 52, 1921. by Harold St. John, 20 BIOLOGICAL SURVEY OF The Tarn Newport Meadow and Newport Mountain THE MOUNT DESERT REGION 21 These range from the cedar swamps where the principal tree is arbor vitae to the ones locally called 'sunken heath,' 'bottomless heath,' etc., which are spring fed, and larch, spruce and the like dominate, with some maples. Brush such as Myrica gale and rank grasses begin in these. Approaching sea level; swamps and 'heaths' are formed where the water is fresh from the land drainage above or salt from the sea's penetration. Such a place is the bog back of Sea Wall and Great Heath in the northwestern part of the island, which is over 2 miles long and is a mile wide in one place. In Swamp l)ack of Schooner Head these the vegetation is brush such as Myrica gale, Kalmia, and the like, while the floor of all of them is Spagnum. These places yield insects and at the same time, test one 's endurance. Although the Island had attracted the attention of botanists for years, and they had published the results, no one did so in the case of insects before the Survey, with the exception of an interesting page and a half on the tiger beetles.*^ A number of butterflies obtained by various collectors visiting Mount Desert are mentioned in Scuclder's great work.'^ " ' ' Cicindelidae of Mt.

Fernald, collected many insects on the Island, which are now in the collection of the Massachusetts Agricnltural College, Amherst, Mass., w^iile the summers of 1909 to 1911 were spent by the late Dr. Charles Sedgwick i\Iinot at Northeast Harbor, who collected at lights, specializing in Lepidoptera. These are in the collection of the New England (Boston) Society of Natural History. In connection with their work on the New England fauna, the New England Society of Natural History, in 1918, selected the Island of Mt. Desert as a place for part of its summer work, this location presenting favorable conditions for a study of insects in relation to life zones, and Mr. Charles W. Johnson, Curator, spent from 10 days to 2 weeks on the Island eacli summer until 1926. We met and joined forces, which resulted in the publication of Part I of the Survey in 1927. Our intention w^as to continue the work together as soon as I was through with the first part of the marine work.^ His passing put an end to that happy association, but left me with the remembrance of one of the best informed and most attractive of naturalists. As a mark of affection I dedicate this book to his memory. LA BOB A TORY The main laboratory of the Survey is situated at Corfiekl on Frenchman's Bay. There, and at Penikese, 5 miles to the westward, light and other traps have been run for several years, from the beginning of May until the end of October. These are not the small traps, but rooms painted white, with glass louvres in the windows, and lights both outside and inside. These lights were changed both as to color and intensity and thus a great number of individuals were taken Avhich, sorted out, yielded many species. Bait traps of differ- ent kinds were run constantly at both of these stations as well as at other parts of the Island. ' Biological Survey of the Mt. Desert Region Parts II, III, IV, V— The Marine Fauna, etc. THE MOUNT DESERT REGION 23 Peiiikese. Tla- liist work ever done on the fauna of the Island Avas done here. View at Corfield 24 BIOLOGICAL SURVEY OF CLASSIFICATION Experience lias taught me that when one looks up a form in a check list, he generally turns to another one, so I have thought it well to follow a recognized list in each of the orders. This naturally makes some of the sequence appear a bit out of date, but when all is said, one turns to the index, and this volume is primarily a check list of the insects that have been found here. I have used in the general classitication the List of the Insects of New York, etc. by M. D. Leonard et al. 1928, which has also been followed in the smaller orders, w^ith the excep- tion of the Ephemeridae, Plecoptera, and Trichoptera, which have been brought up to date to conform with the recent work done on them. Li the Hymenoptera, the same list has been followed, but in the case of parasitic families, some latitude has been taken in listing them, for they are being constantly re-studied, and there is no stable sequence just at present. In the Microlepicloptera it has been used again, but the genera and families are listed in a reverse order so that they may conform to the ^Macrolepidoptera list, and the list that we hope will follow it, for these families. The ]\Iacrolepidoptera are listed as in the recent check list of the Lepidoptera of Canada, and the \J. S. by J. McDunnough 1938. The Catalogue of the Coleoptera of America etc. by Charles W. Leng 1920 has naturally been used for the beetles, while the Hemiptera of Connecticut, etc. by W. E. Britton et al. 1923, has seemed to me the most rational list to use for the Hemiptera. In the Diptera I have used The Families and Genera of North American Diptera by C. H. Curran 1934 in order to bring that order up to date. The Aracnida have the latest classification through the kindness of Dr. W. J. Gertsch. I have been careful to hold to the original names of places that have come down since they were first given and have paid no attention to some fanciful names recently given. The mountains on the island that have gone down in zoological literature under their original names have been renamed and with what imagination! One huge mass of granite now^ bears THE MOUNT DESERT REGION 25 the name of 'Flying Squadron'! That my course is neces- sary is apparent when one realizes that the National Park on the Island is now carrying the third name given to it since this list was started. To students of distribution, variation, and the complexity of insect life, it is important to have a careful survey of the fauna of a region, giving the species found there at a certain time. With this purpose in mind, I have deliberately dis- carded all records that I do not personally know of, and the species here listed, with the exception of about twenty-five which have been entered for purely sentimental reasons, have been taken within the past 20 years. Where any doubt as to a species has come up, it has been determined by a specialist. Furthermore, principally in the cabinets here, and in Boston, Amherst, Washington, or in the collections of specialists who have helped me, any insect mentioned may be found, with the exception of the Mallophaga and two species of bird flies (Hippoboscidae). To acquire actual records of these would necessitate shooting of a large number of birds, the loss of which would not compensate for the little knowledge gained. As over 80% of the birds are infested by these parasites, a list of the species frequenting the more common birds of the Island can be depended upon the represent the approximate number of species. The users of Surveys might well be warned that the publi- cation of one or more species as occurring in a region is obviously no proof that those are the only species in that particular group which do occur. In the following summary the larger and more prominent orders have received the attention. Many groups like the Aphidae, Coccidae, etc., require collecting by specialists. These will be collected, work continued in the larger groups, and the results published. The abundance of the parasite wasps — Ichneumonidae — and the parasitic flies — Tachinidae — indicates a normal or balanced condition, these insects keeping in check the injurious species. 26 BIOLOGICAL SURVEY OF The lady-beetles, lace wings, and syrpliid flies, the great enemies of the plant-lice, are also abundant and largely in- strumental in keeping these prolific and destructive insects within bounds. The rich insect fauna of Mt. Desert shows that we are still dealing in places with an almost undisturbed ecological condition. That this will not continue is apparent, for the gypsy moth is here and will be a major problem as well as the spruce sawfly, while the 'parking' of the woods by removing trees, stumps, etc., will upset the balance still further. Introduced without their parasites and other natural enemies, the only immediate recourse is in spraying with the result that many of our native species disappear, the balance of nature is disturbed and the diversity and heauty of our insect fauna are gone. COLLECTING In order to stimulate interest in the collection and study of insects, I have included notes on how to collect, and where to look for many of the species, for it is my hope that more people will take the trouble to interest themselves in this class. Aside from the aesthetic interest, insects are by far the most interesting of any live thing, when one looks into their habits and life history. Few people realize that man is abso- lutely dependent upon insects for his existence. Fewer still know anything about them. Finally, I expect to issue supplements to this list from time to time, and I hope that anyone who wishes to include any insects taken on the Island will send me authentic records. Also in this list as in all others there must be some errors. Please call them to my attention so that corrections may be made in the supplements.

The May Flies The proper way to collect this order is to wade up brooks gently sweeping the vegetation on either side, just at dusk, or to work around the edges of ponds at the same time. When- ever there is a strong wind blowing across a pond and a hatch is on, the flies will be carried to the leeward side and often to a considerable distance, and sweeping and examining trunks of trees along the edge of the pond will produce results. Dr. H. T. Spieth tells me that the tendency of the flies when leav- ing the brook is to go toward the dark, and that the males will go up the side of clitTs to a considerable height.

Large numbers in 1937 and 1938. Carabidae. The Ground Beetles They are to be looked for on the ground where they hide under stones and other cover. Some prefer the edges of ponds; others, dry places, while still others are found in sphagnum moss or wet moss in deep woods. Some of our species fly freely on warm spring mornings, particularly near wet places. The way to take the bog species is to stamp around on the surface of the bog and drown them out. I have found by working potato patches and turning over the stones, a week or two after the crop has been harvested, a most fruit- ful field. The molasses trap is very successful. 88 BIOLOGICAL, SURVEY OF ScAPHiNOTUS Dejean S. YiDuus (Dej.) (128). On August 24, '32, quite a number of these beetles appeared in the garden of Mrs. E. C. Bodman at Seal Harbor and they have never been found either be- fore or since, although carefully searched for. Their food is land snails. NoMARETTJS LeConte N. BiLOBus (Say) (134). This species has never been taken on the Island, probably because of the scarcity of its natural food, the land snails. It is found on Long Porcupine Island where there are snails, around the first of July, in decay- ing white birch logs. Sphaeoderus Dejean S. LEcoNTEi Dej. (162).

THE MOUNT DESERT REGION 97 HALiPLroAE. The Crawling Water Beetles They live around the margins of brooks and ponds where they crawl over the aquatic plants that lie flat on the water. Best taken by raking vegetation onto a screen and looking- for them as the material dries. Haliplus Latreille H. RUFicoLLis DeG. (2318). All in the genus live in shallow pools where they may be taken crawling on aquatic plants. Ireson Hill Pd., Sept.^ 30; New Mill Pd., Aug. 7. Dytiscidae. The Diving: Beetles These predaceous ones live in pools and the most sure way to take large ones is to suspend a minnow trap baited with a piece of fish. The opening of the trap should not be too large. Scraping the edges of pools will get the others. Laccophilus Leach L. MAcuLOSus (Germ.) (2351). This 'pool loving' species, as its name indicates, is commonly found in the smaller pools on the Island. It is the first of the family to appear in the spring, and remains until cold weather, when it probably hibernates. CoELAMBUS Tliomsoii C. iNAEQUALis (Fab.) (2403). Pare, having been taken but once.

This species had never been seen on the Island until taken in large numbers at the same time and place as that next below. D. DAUEicus Gebl. (2645). This species is found in very few numbers in the smaller ponds. On July 30, '35, a man in Tremont reported that his trout were being eaten up by lizards. Upon investigation they proved to be the 'water tigers' of this and (D. verticalis) and the pool was fairly swarming with the adults, they having evidently hatched during the previous week. Upon investigation, this spring which had been made into a pool, had no connection with any other body of water, and was on a hill and therefore the absence of the eels, which are the common enemy of this family, permitted them to multiply in peace. D. sp. A 'tiger' in the house Bar Harbor, June. (Dr. Thorn- dike.) Achjus Leach A. sEMisuLCATUS Aube (2651).

The Click Beetles All of the species of this family are vegetable feeders, either upon the roots of grasses or the juices of rotten wood. The larvae are known as Svire-worms ' and are difficult to raise, as many require several years to complete their growth. They are best collected by beating and from old logs and stumps, but many may be lured to sweet bait on trees w^hich should be visited at night. Some of the most scarce and interesting species occur on the earliest 'catkins.' Adelocbra Latreille A. OBTECTA (Say) (8558). A northern form. Taken from under the bark of dead trees, Eden, June 25.

This species rolls the leaves of oak. Bar Harbor beating June 16. Rare. A. RHois Boh. (16369). Occurs on hazelnut and alder. As described by Packard, the singTilar, thimble-like rolls of this weevil may be found in June and July on the alder. When about to lay her eggs, the female begins to eat a slit near the base of the leaf on each side of the midrib, and at right angles to it, so that the leaf may be folded together. Before beginning to roll up the leaf she gnaws the stem nearly off, so that after the roll is made, and has dried for perhaps a day, it is easily detached by the wind and falls to the ground. When folding the leaf, she tightly rolls it up, neatly tucking in the ends, until a compact cylindrical solid mass of vegetation is formed. Before the leaf is entirely rolled she deposits a single egg, rarely two, in the middle next to the midrib, where it lies loosely in a little cavity. These rolls remain on the bushes sometimes for several days, but probably drop by the time the larva escapes from the egg, and it seems probable that the grub uses the roll for a shelter until it matures and is ready to enter on its transformation to a beetle.

Mr. Scudder on the distribution of this species in his "Butter- flies of New England," says: "Mt. Desert, Me., a single specimen seen (Thaxter)." Again on page 1132, he says: *'Mr. Thaxter was attracted to the specimen which he took at Mt. Desert by the orange color of the wings, and says the butterfly was apparently dancing in nuptial pas de deux with a companion; they twirled high into the air beyond reach, but soon separated and came to earth again, when one was captured."

Formerly common throughout northern New England, but since the introduction of Pieris rapae, it has become com- paratively scarce, probably owing to parasites. The larva feeds on mustard, cabbage, turnip, and other Cruciferae. P. RAPAE Linn. (86). Imported Cabbage-butterfly. Common. Litroduced at Quebec about 1860, it reached Mt. Desert about 1868. The larva feeds chiefly on cabbage, but will also feed on most of the Cruciferae, including turnip, mus- tard, horse radish, water-cress, etc. It is usually kept in check by parasites.

Desert. In discussing- the probable occurrence of prosperpina at Halifax, Nova Scotia, Mr. Scudder says: ''It is not at all improbable that Ursula (astyanax) may yet be found as far north as Mt. Desert, and that colonies of prosperpina are now living along the whole coast of Maine." (See Butterflies of New England, vol. 1, p. 291, 1889.) B. ARCHippus Cram. (325). The Viceroy. Not common.

Corfield, Oct. 282 BIOLOGICAL SURVEY OF TiPULiDAE. The Crane Flies TiPULINAE In 1926 Dr. C. P. Alexander of Amherst, Mass., visited the Island, stopping at Southwest Harbor, and found it ^'certainly one of the richest and most remarkable faunas anywhere in the world." For that reason, most careful collecting has been done in this family, and Doctor Alexander and our friend, Mr. Walter H. Harrison, the botanist, have made trips to the Island for a few days during the past three years. They Doctor Brower, and the writer, have collected together and separately, and while the 197 species fall short of our goal of 200, there is no doubt that the elusive three species, as well as others, will be found by the time the supplement to this list is published. We have had some of our happiest days in this search, which we shall continue. The letter (J) is for Johnson, and the other three are represented by their initials. In the Occasional Papers of the Boston Society of Natural History, Vol. V, pp. 223-231, January 12, 1937, being part of the second Supplementary List, Doctor Alexander gives many records of species taken on the Island. To combine them with the list below would be confusing, and reference is therefore made to this paper, particularly because Doctor Alexander discusses some of the habitats, which should be read in connection with the listed species.

During the first warm days in spring, the adults emerge and eggs are laid on the first colonies of aphids appearing on the shoots of various plants, and they continue through the summer liv- ing on various forms of aphids and undoubtedly destroy many of the sexual females in September. Taken as late as September 22nd. Owing to an open winter, there was a large aphid population in the spring of 1937, and by the first of July these flies were in enormous quantities and would rise in swarms, while at the same time the numbers in the other species in the genus remained the same as other years.
