Book Description
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.

Book Description
Excerpt from A Handbook of the Dragonflies of North America Owing to the insistence of other duties the completion of this book has been long delayed. Many of the pupils of the senior author have contributed materials for it. It is no longer possible to name them all, but the help of all is gratefully acknowledged. In the final putting together of these materials there are those who have aided so well and so generously as to deserve special mention. Mrs. H. E. Seemann assisted in the preparation of materials and drawings. Miss Elsie Broughton helped with the completion of both drawings and manuscript; and most of the drawings of genitalia were made by Mr. 0. Francis Byers. Whole sections of the text have been written by the two last named. Dr. P. P. Calvert has very kindly read the galley proofs, and has helped with useful alterations and amend ments. He has enabled us to eliminate some errors, but for such as may remain he is in no way responsible. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
A comprehensive, fully illustrated guide to every dragonfly species found in North America Dragonflies are large and beautiful insects, diverse in color and pattern. This premier field guide provides all the information you need to identify every male and female dragonfly found in North America, whether in the field, in the hand, or under the microscope. The extensive illustrations are the heart of the book. Close-up color portraits of each species, often several times life size, show the best possible specimens for close examination. Each sex is depicted using multiple images, with postures and viewpoints consistently maintained to aid comparison. Dragonflies of North America is the ultimate guide to these extraordinary insects. Covers all 329 North American species, including distinctive subspecies and variations Features nearly 1,900 highly detailed paintings and drawings, providing clarity and consistency that photographs cannot match Illustrates each species with multiple views for easy identification and comparison Gives an invaluable introduction to dragonfly anatomy, behavior, and life cycle Offers additional guidance for the most challenging species that defy field identification, highlighting anatomical characteristics to aid identification in the hand Includes a distribution map for every species
