This research level text documents the latest advances in odonate biology and relates these to a broader ecological and evolutionary research agenda. Despite being one of the smallest insect orders, dragonflies offer a number of advantages for both laboratory and field studies. In fact, they continue to make a crucial contribution to the advancement of our broader understanding of insect ecology and evolution. This new edition provides a critical summary of the major advances in these fields. The editors have carefully assembled a fresh set of contributions from a diverse geographic mix of both junior and senior researchers in dragonfly biology to offer new perspectives and paradigms as well as additional, unpublished data. These include theoretical and applied chapters (including those addressing conservation and monitoring) as well as a balance of emerging (e.g. molecular evolution) and established research topics, providing suggestions for future study in each case. This accessible text is not about dragonflies per se but is an essential source of knowledge that describes how different sets of evolutionary and ecological principles and ideas have been tested on a particular taxon. Dragonflies and Damselflies is suitable for graduate students and researchers in entomology, evolutionary biology, population and behavioural ecology, community ecology, and conservation biology. It will be of particular interest and use to those working on insects and an indispensable reference text for odonate biologists.

More than one hundred and fifty species of dragonflies and damselflies most likely to be seen throughout the U.S. Southeast north of Florida are covered in this abundantly illustrated guide that is organized for easy use in the field and contains information on the insects' life cycles, taxonomy, characteristics, habitats, distribution, behavior, and identification.

Dragonflies and Damselflies of the West is the first fully illustrated field guide to all 348 species of dragonflies and damselflies in western North America. Dragonflies and damselflies are large, stunningly beautiful insects, as readily observable as birds and butterflies. This unique guide makes identifying them easy--its compact size and user-friendly design make it the only guide you need in the field. Every species is generously illustrated with full-color photographs and a distribution map, and structural features are illustrated where they aid in-hand identification. Detailed species accounts include information on size, distribution, flight season, similar species, habitat, and natural history. Dennis Paulson's introduction provides an essential primer on the biology, natural history, and conservation of these important and fascinating insects, along with helpful tips on how to observe and photograph them. Dragonflies and Damselflies of the West is the field guide naturalists, conservationists, and dragonfly enthusiasts have been waiting for. Covers all 348 western species in detail Features a wealth of color photographs Provides a color distribution map for every species Includes helpful identification tips Serves as an essential introduction to dragonflies and their natural history

The definitive single-volume fully illustrated guide This is the first fully illustrated guide to all 336 dragonfly and damselfly species of eastern North America—from the rivers of Manitoba to the Florida cypress swamps—and the companion volume to Dennis Paulson's acclaimed field guide to the dragonflies and damselflies of the West. Dragonflies and Damselflies of the East features hundreds of color photos that depict all the species found in the region, detailed line drawings to aid in-hand identification, and a color distribution map for every species—and the book's compact size and user-friendly design make it the only guide you need in the field. Species accounts describe key identification features, distribution, flight season, similar species, habitat, and natural history. Paulson's authoritative introduction offers a primer on dragonfly biology and identification, and also includes tips on how to study and photograph these stunningly beautiful insects. Illustrates all 336 eastern species Features hundreds of full-color photos Includes detailed species accounts, line drawings to aid identification, and a color distribution map for every species Offers helpful tips for the dragonfly enthusiast

This monograph is the first of its kind devoted entirely to the dragonfly nymphs of North America north of Mexico, the focus being accurate identification of the 330 species of Anisoptera that occur in the region. Nymphal external morphology is described and illustrated in detail, and all terms needed to navigate the dichotomous keys are defined. Species are tabulated with references that provide the most detailed, accurate descriptions for each; species that are inadequately described are so indicated. The key separating the seven families in the region contains several new characters. The families are then covered separately: Aeshnidae (13 genera), Gomphidae (17 genera), Petaluridae (2 genera), Cordulegastridae (2 genera), Macromiidae (2 genera), Corduliidae (7 genera), and Libellulidae (29 genera). Each family is further characterized, followed by a generic key. A drawing of the habitus and diagnostic details for each genus are provided, along with additional diagnostic remarks and notes on habitat and life cycle; for each genus, a map shows its geographic distribution in North America. Full-grown nymphs of all known species of each genus are keyed and diagnosed; characters that apply to earlier instars are noted. Morphological variation in character states was analyzed in order to assess the reliability of previously utilized characters and to discover new characters. Most of the characters used to distinguish all levels of taxa are illustrated; a total of 702 figures, comprising 1,800 original drawings, along with selected photographs where necessary for clarity, accompany the keys. Measurements of total length, head width, and other variables for each species are provided in tables. Difficulties with past keys and descriptions, including errors, omissions and other shortcomings, are addressed. The importance of nymph characters in helping solve generic and specific distinctions and their role in phylogenetic studies is emphasized. Methods for collecting, rearing, and preserving dragonfly nymphs and exuviae are presented. The final chapter discusses research opportunities on North American Anisoptera nymphs, including taxonomic needs, studies on structure and function, life history and microhabitat, water quality indices and conservation efforts. The habitus drawings of all genera are arranged according to family in five plates (Appendix I); although the book is intended as a lab manual, these plates conveniently allow for comparison based on nymph shape making field identification to genus possible in many cases. Appendix II contains a brief history of dragonfly nymph studies in North America. A glossary and an index to scientific names are included.

A comprehensive guide to all 44 species of North Woods damselflies, exclusively for Minnesota, Wisconsin and Michigan. The book's innovative format shows: 120 color photos of all North Woods, easy-to-use phenograms, and bars on photos which indicate damselfly length.
