A Survey of the Lepidoptera, Biogeograhy and Ecology of New Caledonia


Book Description

I spent four months in New Caledonia in 1971 with the object of making a quantitative survey of the night-flying macrolepidoptera with light-traps and an assessment of the Rhopalocera and microlepidoptera. This fieldwork was financed by a Government Grant-in-Aid for Scientific Investigations adminis tered by the Royal Society, and by a grant from the Godman Fund. I devoted a further three weeks to sampling on Norfolk I. , and, with the help of local naturalists, Mr. and Mrs. F. JOWETT, was able to produce a detailed account of the biogeography and ecology of the moth fauna (HOLLOWAY, 1977). This book is an account of the results of the New Caledonian work, together with reviews of the geology, phytogeography and general zoogeography pre sented as background for the Lepidoptera fauna and its geography. Previous work on the macroheterocera, primarily papers by VIETTE (1948- 1971), had recorded not many more than a hundred species, a very low total considering the area of the island relative to that of the Fiji group where the moths were being studied by Dr. G. S. ROBINSON when the New Caledonian expedition was at the planning stage. The Fijian fauna then promised consider ably to exceed three hundred species. Evidently many more species awaited discovery in New Caledonia.




Biodiversity and Ecology of Lepidoptera - Insights and Advances


Book Description

Biodiversity and Ecology of Lepidoptera - Insights and Advances presents a comprehensive overview of the order of winged insects known as Lepidoptera. It is organized into two sections and seven chapters. Section 1, "Lepidoptera: Behavioural Diversity", explores the myriad challenges faced by Lepidoptera globally. In the twenty-first century, the most pressing issue confronting them is the decline in biodiversity, necessitating the essential restoration of ecosystems. Concurrently, Lepidoptera exhibit mastery in camouflage and mimicry, enabling them to evade detection by predators and parasites, providing a reproductive advantage. This section also delves into gynandromorphy behavior, where individuals develop a mosaic of both male and female traits, with the left and right halves of the body displaying different sexes. Additionally, it reviews recent advances in non-coding RNAs, elucidating their role in regulating gene expression through chromosomes and their significance in the overall developmental process of Lepidoptera. Section 2, "Moths: Bioecology and Genetics", commences with the mapping of flight paths for feeding, reproduction, and pollination occurrence in hawkmoths in the family Sphingidae. The section then reveals the features of invasion into various ecosystems by five invasive leafminer moth species of the family Gracillariidae). Furthermore, it discusses the degree of genetic variability and phylogenetic relationships among 13 breeds of the mulberry silkworm (Bombyx mori L.).




Courtship and Mating in Butterflies


Book Description

The aim of this book is to present a readable account of butterfly behaviour, based on field observations, great photographs and the latest research. The main focus is on courtship and mating – including perching, searching and territorial behaviour – but to understand these subjects it is necessary to explain how mates are chosen and this requires sections on wing colours and patterns. A chapter on butterfly vision is also essential in terms of how butterflies see the world and each other. There have been exciting discoveries in all of these fields in recent years, including: butterfly vision (butterfly photoreceptors), wing patterns (molecular biology), wing colouration (structural colours and nano-architecture), mating strategies and female choice (ecology and behaviour).




Moths of Western North America


Book Description

"Two of North America's most prolific and respected specialists on moths--particularly those of the West--have combined over a century of experience and scholarship to introduce western moths of all families authoritatively to both the amateur and the experienced professional entomologist. This biologically oriented and beautifully illustrated treatment of a quarter of all known western moth species fills a long-needed void, and does it superbly."--Charles V. Covell Jr., author of A Field Guide to Moths of Eastern North America "This work sets a new high water mark for North American lepidopterology. Considering the authors' century of combined studies of western Lepidoptera, it is clear from the outset that no other team could have delivered a work so rich in taxonomic and life history information, much of it being original and appearing in the literature for the first time. I will read my copy more like a novel than a reference work, casting about the accounts and repeatedly flipping through the 2300 color images to better familiarize myself with our continent's rich and handsome diversity of moths. Moths of Western North America will serve as both gateway and catalyst for the study of moths for decades, and especially for microlepidopterans--for whom no like work exists in the New World."--David L. Wagner, author of Caterpillars of Eastern North America "Recent years have seen a surge of interest in moths, with growing appreciation of their amazing diversity and their great ecological importance. Information on western moths has been scattered and scarce, however, so this new volume is a tremendous step forward. Jerry Powell and Paul Opler bring a vast amount of knowledge and experience to the subject, and their Moths of Western North America is a landmark publication, instantly indispensable to anyone with a serious interest in Lepidoptera."--Kenn Kaufman, coauthor of Kaufman Field Guide to Butterflies of North America




Lepidopterorum Catalogus


Book Description

The noctuidae of the world, a family with numerous important agricultural pests, comprises about a third of the entire order Lepidoptera. This new three-volume set is the first complete catalog for the world. About 38,000 named species (including known synonyms) are listed alphabetically under each genus name in over 1,000 pages of text. Genera area also listed alphabetically, but subfamily affiliations are noted for each of the valid names to enable users to segregate genera by subfamily. Valid names are noted in boldface. Synonyms are listed for each genus and species; the species synonyms are also listed alphabetically among the valid names, thus enabling users to make two kinds of searches in the text as well as in the index. The catalog provides citation data on all described names (other than infraspecific names), with references cited in the compete bibliography at the end. Reference is also made to more important papers on the biology, larvae, host plants, and illustrations for each species, again with full titles noted in the bibliography. The main host plants for each species, where known, are listed under each. Details of holotypes, where known, are also noted. The bibliography has entries for approximately 4,400 papers.




Butterflies of the East Coast


Book Description

Here is an accessible, informative, and highly illustrated book that offers a fresh view of butterflies in the East Coast states, from the Atlantic seaboard to the Appalachians. In addition to providing a wealth of facts and photos, the book is the first to furnish detailed and up-to-date photo-illustrated information on the host plants favored by particular species. With 234 full-page species accounts and accompanying range maps, plus more than 950 large-size color photos, it is an essential reference work for field observers, gardeners, educators, and conservation managers--or anyone interested in appreciating the lepidopteran world close at hand. The introductory chapters detail the subtle ecology of the East Coast region, establishing a consistent ecological framework that enriches the individual species accounts. There is also an overview of current scientific literature and observational findings to help readers better interpret complex butterfly behaviors in the field, including seasonal movements, host plant and diapause strategies, defensive chemistry, and more. The book is written by Rick Cech, a seasoned field observer who has spent years studying and photographing East Coast butterflies. His substantial first-hand experience with both the common and rare species in the region adds much depth and new insight to the commentary. 234 full-page species accounts and accompanying range maps 950 large-size color photos 215 photos of individual host plants and habitats 735 high-quality photos of butterflies and caterpillars Introductory chapters detailing the subtle ecology of the East Coast region An overview of current scientific literature and observational findings Descriptions of diapause and host plant strategies and defensive chemistry User-friendly with clear, concise text
