Attraction of Butterflies to Light 1964 Journal of the Lepidopterists' Society 73 The pupa of P. indra minol'i is nearly identical to the pupa of P. indra fordi (illustrated in Comstock & Martin, 1955). The ground color is a grayish tan, with short light and dark streaks giving all surfaces except the wing cases a lightly mottled appearance. The wing cases are pre­ dominantly olive-tan. Thc surface is rough with a profusion of tiny raised points and small wart-like nodules. There are two longitudinal rows of papillae extending posteriorly from the thoracic region: one row on each side of the dorsal area, and a second row placed suprastigmatally. These papillae are not lightly colored and conspicuous, as opposed to those on the pupa of P. indra tordi. ACKNOWLE DGEMENTS The present paper is part of a continuing study of species of the Pa}Jilio machaon complex in western North America. The aid of the Cordon F. Ferris Memorial Scholarship (to J. F. E.) from Stanford University is gl'atefully acknowledged . .Mr. Will C . .Minor of Fruita, Colorado, was exceedingly helpful during our visit to the Black Ridge area. Superintendent F. C. Bussey and Naturalist Clarence J. .McCoy of the National Park Service were most helpful in granting us a collecting pern1it to collect within Colorado National Monument and in answering our many questions about the area and its butterfly fauna. Mr. Donald Eff of Boulder, Colorado, very kindly supplied 11S with a living female of P. indra minori and detailed information on the type locality. Dr. Paul R. Ehrlich, Division of Systematic Biology, Stanford University, reviewed the manuscript and offered helpful assistance at the Rocky Mountain Biological Laboratory.

ATTRACTION OF BUTTERFLIES TO LICHT by D. C. SEVASTOPULO P. O. Box 5026, Mombasa, KENYA With reference to Mr. Donohue's note (Journ. lepid. soc. 16: 131- 132; 1962), the paucity of Indian records of butterflies attracted to light can, I think, be explained partly by the fact that the older generation of entomologists saw nothing remarkable in the occasional visit of a 74 EMMEL and EMMEL: Papilio biology Vol.IS: no.2 butterfly to light; after all many other day-flying, sun-loving insects are so attracted, for example dragonflies, cicadas, grasshoppers, both long and short horned, plant bugs, bees, wasps, day-flying moths, etc., and partly because it is only comparatively recently that electric light has been extended to cover the smaller places. I have published no records of butterflies attracted to light in India, but the crepuscular Melanitis leda L. and Gangara thyrsis F. were both fairly frequent visitors. In Calcutta, the satyrid Elyrnnias hypermnestra undltlaris Drury and the hesperiid Suastus grernius F., both of whose larvae feed on palms growing in verandahs, also appeared not infre­ quently. In 1948, near Pantellaria Island in the Mediterranean, my ship passed through a migration of Vanessa cardui L., and a number of them were attracted to the ship's lights that evening (Entomologist 81: 186; 1948). \Vorking a mercury vapour lamp in East Africa has provided a very large number of records, some of which have been published in 1955 and 1958 (Entomologist 88: 37; 91: 86), and I give below a full list of the species that have been attracted. Some of these have been pub­ lished previously and some have not. For the sake of completeness I have added the names of some day-flying moths that have also been attracted.

  • Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
    ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4.

  • Butterflies As an Indicator Group for the Conservation Value of the Gola Forests in Sierra Leone
    BUTTERFLIES AS AN INDICATOR GROUP FOR THE CONSERVATION VALUE OF THE GOLA FORESTS IN SIERRA LEONE Claudio Belcastro* & Torben B. Larsen** * Lungotevere di Pietro Papa 21 00146 Roma, Italia [email protected] ** 358 Coldharbour Lane London SW9 8PL, UK [email protected] EXECUTIVE SUMMARY Less than 5% of Sierra Leone’s original forest cover still exists, though some of that hardly merits the term forest. Besides the remaining forest on the Freetown Peninsula, and the important Loma and Tingi Mountains, with their submontane elements, Gola Forest is the most significant forest in the country. During late April, 2006, a one week field-trip was made to study the butterflies of the Gola Forests by two separate teams, headed by one of the authors of this report. Belcastro also returned to Gola North for three days in early May. In all, 370 species were positively recorded. The estimated total for the area is about 600, accounting for about 80% of the 750 or so known Sierra Leone butterflies. Many rare and interesting butterflies occur and, in general, the Gola Forests are now the westernmost outpost of the West African forest fauna. Many species endemic to Africa west of the Dahomey Gap and to its Liberia subregion were found in Gola. The fact that so many rare and interesting species were collected in, sometimes quite heavily, logged areas of Gola is a strong indicator that the forests have the capacity to return to a state that resembles the original over the next 25 years. In Gola (South), and especially in Gola (North), there appear to be areas of undisturbed forest that act as reservoirs of biodiversity that help to re-populate the regenerating parts of the forest.

  • Predatory and Parasitic Lepidoptera: Carnivores Living on Plants
    Journal of the Lepidopterists' Society 49(4), 1995, 412-453 PREDATORY AND PARASITIC LEPIDOPTERA: CARNIVORES LIVING ON PLANTS NAOMI E. PIERCE Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts, 02138, USA ABSTRACT. Moths and butterflies whose larvae do not feed on plants represent a decided minority slice of lepidopteran diversity, yet offer insights into the ecology and evolution of feeding habits. This paper summarizes the life histories of the known pred­ atory and parasitic lepidopteran taxa, focusing in detail on current research in the butterfly family Lycaenidae, a group disproportionately rich in aphytophagous feeders and myr­ mecophilous habits. More than 99 percent of the 160,000 species of Lepidoptera eat plants (Strong et al. 1984, Common 1990). Plant feeding is generally associated with high rates of evolutionary diversification-while only 9 of the 30 extant orders of insects (Kristensen 1991) feed on plants, these orders contain more than half of the total number of insect species (Ehrlich & Raven 1964, Southwood 1973, Mitter et al. 1988, cf. Labandiera & Sepkoski 1993). Phytophagous species are characterized by specialized diets, with fewer than 10 percent having host ranges of more than three plant families (Bernays 1988, 1989), and butterflies being particularly host plant-specific (e.g., Remington & Pease 1955, Remington 1963, Ehrlich & Raven 1964). This kind of life history specialization and its effects on population structure may have contributed to the diversification of phytophages by promoting population subdivision and isolation (Futuyma & Moreno 1988, Thompson 1994). Many studies have identified selective forces giving rise to differences in niche breadth (Berenbaum 1981, Scriber 1983, Rausher 1983, Denno & McClure 1983, Strong et al.

  • Lycaenidae) and Ants (Formicidae, Hymenoptera
    190 JOURNAL OF THE LEPIDOPTERISTS' SOCIETY NEW ASPECTS ON THE ASSOCIATION BETWEEN LYCAENID LARVAE (LYCAENIDAE) AND ANTS (FORMICIDAE, HYMENOPTERA) HANS MALICKY Limnologisches Institut cler Osterreichischen Akaclemie cler ,,y issenschaften, A-3293 Lunz, Austria Introduction The assaciation between lycaenid larvae and ants is well known and has been discussed several times in the literature. The most recent survey is by Hintan (1951). Since the majority af published reports are purely descriptivc it would seem both desirable and necessary to' consider the evolutionary saurces of the association using an experimental approach. It is the purpase of this paper ta present a summary af the essential facts and new thoughts bearing on this associatian based on this approach; de­ tails af these investigations will be published elsewhere. Current Hypatheses The best known hypathesis advanced to explain the relatianship be­ tween ants and the larvae originated with Thomann (1901). He suggested that ants are able to drive away the caterpillar's parasites, so that the lycaenids benefit fram the presence af the ant. In order to attract the ants and keep them in attendance, the caterpillars exude a haney-like liquid fram a particular glandular argan, which was first described by Newcamer ( 1912). According to this hypathesis the assaciatian is a symbiasis. This hypathesis, hawever, has several weak paints. Firstly, it has not been canfirmed that ants are able ta drive away parasitic Ichneumonidae and Tachinidae or even natice their presence. Secandly, there is na evidence that the presence af the ant lawers significantly the rate of parasitism af the caterpillars. Field abscrvatians by this writer shaw that the degree af parasitism af lycaenid larvae fluctuates widely, as is usual in Lepidaptera, whether ants are present ar absent.

  • The Butterflies and Skippers (Lepidoptera: Papilionoidea) of Angola: an Updated Checklist
    Chapter 10 The Butterflies and Skippers (Lepidoptera: Papilionoidea) of Angola: An Updated Checklist Luís F. Mendes, A. Bivar-de-Sousa, and Mark C. Williams Abstract Presently, 792 species/subspecies of butterflies and skippers (Lepidoptera: Papilionoidea) are known from Angola, a country with a rich diversity of habitats, but where extensive areas remain unsurveyed and where systematic collecting pro- grammes have not been undertaken. Only three species were known from Angola in 1820. From the beginning of the twenty-first century, many new species have been described and more than 220 faunistic novelties have been assigned. As a whole, of the 792 taxa now listed for Angola, 57 species/subspecies are endemic and almost the same number are known to be near-endemics, shared by Angola and by one or another neighbouring country. The Nymphalidae are the most diverse family. The Lycaenidae and Papilionidae have the highest levels of endemism. A revised check- list with taxonomic and ecological notes is presented and the development of knowl- edge of the superfamily over time in Angola is analysed.
