Book Description
This study, the first in an intended series of anatomical investigations of the blister beetles, was undertaken primarily for the purpose of determining the changes that occur in the skeletal musculature during postembryonic larval development. The species studied, Epicauta segmenta (Say), like others belong ing to the coleopterous family Meloidae, is characterized by hypermetamor phosis (SELANDER and WEDDLE, 1969). The egg develops into an active, well sclerotized larva that searches for grasshopper eggs, which, as in the case of all species of Epicauta, serve as the sole larval food. This triungulin phase of the larval stage, as it is called, is followed by the first grub phase (Fig. 1), during which the larva continues to feed and undergoes several molts. After feeding is completed the larva commonly enters a sessile, diapausing coarctate phase in which the integument is heavily sclerotized and the appendages, including the legs, are vestigial (Fig. 2). Following this the larva attains an active second grub phase (Fig. 3) closely resembling the first grub phase in external anatomy. Normally, the second grub phase leads directly to pupation and the formation of the adult. An alternate, abbreviated developmental pattern, involving pupation immediately after the first grub phase, is also recorded in this and many other species of Epicauta.

seem as appropriate now as the original balance was when Dr A. D. Imms' textbook was first published over fifty years ago. There are 35 new figures, all based on published illustrations, the sources of which are acknowledged in the captions. We are grateful to the authors concerned and also to Miss K. Priest of Messrs Chapman & Hall, who saved us from many errors and omissions, and to Mrs R. G. Davies for substantial help in preparing the bibliographies and checking references. London O. W. R. R. G. D. May 1976 Part III THEORDERSOFINSECTS THE CLASSIFICATION AND PHYLOGENY OF INSECTS The classification of insects has passed through many changes and with the growth of detailed knowledge an increasing number of orders has come to be recognized. Handlirsch (1908) and Wilson and Doner (1937) have reviewed the earlier attempts at classification, among which the schemes of Brauer (1885), Sharp (1899) and Borner (1904) did much to define the more distinctive recent orders. In 1908 Handlirsch published a more revolutionary system, incorporating recent and fossil forms, which gave the Collembola, Thysanura and Diplura the status of three independent Arthropodan classes and considered as separate orders such groups as the Sialoidea, Raphidioidea, Heteroptera and Homoptera. He also split up the old order Orthoptera, gave its components ordinal rank and regrouped them with some of the other orders into a subclass Orthopteroidea and another subclass Blattaeformia.

Book Description
Seit der Herausgabe des umfassenden Werkes von GHJLAROV (1964) über die boden bewohnenden Insektenlarven hat sich unser Wissen über Käferlarven bedeutend erweitert. GHJLAROV führt bei gleicher Auffassung der Familien in seinem Familien schlüssel 70 Taxa an (hier 93). Nach den Tabellen der einzelnen Familien sind durch sein Buch ca. 470 Gattungen bestimmbar (hier 653). Außerdem wurden in den vorliegenden Band 16 Familien aufgenommen, für die GHJLAROV keinen Gattungs schlüssel bringt. Es ist nicht möglich gewesen, Tabellen bis zur Art (wie bei GHJLA ROV} aufzunehmen. Für später ist eine Fortführung dieses Buches geplant, und es sollen Bestimmungstabellen bis zu den Arten geschaffen werden. Auf den ersten Blick mag es verwunderlich erscheinen, wenn Familien, die vor wiegend in Pilzen leben (z. B. Mycetophagidae), Bewohner faulenden Holzes (z. B. Serropalpidae) oder Familien, die vorwiegend in der Kraut- und Strauchschicht leben (z. B. Ooccinellidae) in dieses Buch aufgenommen wurden. Tatsächlich ist es aber so, daß alle hier behandelten Familien in Material aus Bodenfallen mehr oder minder regelmäßig gefunden werden. Die eigentlich nicht zur Fauna des Bodens oder der Bodenoberfläche gehörenden Ooccinellidae wurden beispielsweise mit 15,4% aller Käferlarven bei einer Untersuchung über die epigäische Fauna von Fichtenwäldern nachgewiesen. Es wurde darauf verzichtet, dieser Arbeit eine ver gleichende Morphologie der Coleopte;renlarven voranzustellen. Die wesentlichsten Bestimmungsmerkmale werden anschlieQend in einer kurzen Übersicht erläutert. Ziel des vorliegenden Buches ist eine möglichst leichte Diagnose von Käferlarven.

Awarded Best Reference by the New York Public Library (2004), Outstanding Academic Title by CHOICE (2003), and AAP/PSP 2003 Best Single Volume Reference/Sciences by Association of American Publishers' Professional Scholarly Publishing Division, the first edition of Encyclopedia of Insects was acclaimed as the most comprehensive work devoted to insects. Covering all aspects of insect anatomy, physiology, evolution, behavior, reproduction, ecology, and disease, as well as issues of exploitation, conservation, and management, this book sets the standard in entomology. The second edition of this reference will continue the tradition by providing the most comprehensive, useful, and up-to-date resource for professionals. Expanded sections in forensic entomology, biotechnology and Drosphila, reflect the full update of over 300 topics. Articles contributed by over 260 high profile and internationally recognized entomologists provide definitive facts regarding all insects from ants, beetles, and butterflies to yellow jackets, zoraptera, and zygentoma. - 66% NEW and revised content by over 200 international experts - New chapters on Bedbugs, Ekbom Syndrome, Human History, Genomics, Vinegaroons - Expanded sections on insect-human interactions, genomics, biotechnology, and ecology - Each of the 273 articles updated to reflect the advances which have taken place in entomology research since the previous edition - Features 1,000 full-color photographs, figures and tables - A full glossary, 1,700 cross-references, 3,000 bibliographic entries, and online access save research time - Updated with online access

Book Description
This book is devoted to the ichnology of insects, and associated trace fossils, in soils and paleosols. The traces described here, mostly nests and pupation chambers, include one of the most complex architectures produced by animals. Chapters explore the walls, shapes and fillings of trace fossils followed by their classifications and ichnotaxonomy. Detailed descriptions and interpretations for different groups of insects like bees, ants, termites, dung beetles and wasps are also provided. Chapters also highlight the the paleoenvironmental significance of insect trace fossils in paleosols for paleontological reconstructions, sedimentological interpretation, and ichnofabrics analysis. Readers will discover how insect trace fossils act as physical evidence for reconstructing the evolution of behavior, phylogenies, past geographical distributions, and to know how insects achieved some of the more complex architectures. The book will appeal to researchers and graduate students in ichnology, sedimentology, paleopedology, and entomology and readers interested in insect architecture.
