An indispensable guide to Great Britain and Ireland's resident and migrant dragonfly and damselfly species. Whizzing over water with metallic bodies and often iridescent wings, dragonflies and damselflies are arguably one of our most overlooked and beautiful insects. This practical guide will help you to distinguish between skimmers and darters, with fascinating species accounts and insect-watching tips. To aid quick and accurate identification, the book also contains more than 280 stunning paintings by renowned artist, Richard Lewington. The 2002 edition was shortlisted for the BP Natural World Book Prize. This updated edition has been fully revised and redesigned to feature full descriptions, ecological notes and distribution maps, as well as a general introduction and regional guide to the best places to watch dragonflies.
A revised and thoroughly updated edition of the definitive guide to identifying dragonflies in Europe. The first edition of the Field Guide to the Dragonflies of Britain and Europe was a ground-breaking identification guide that led to an increase in Odonata recording across Europe. The second edition includes fully revised regional guides and identification texts, updated distribution maps and conservation statuses, illustrated accounts for five species that have been discovered in the region since the first edition, updated checklists and taxonomy, and new photographs throughout, as well as an introduction to larvae identification. Each species is lavishly illustrated with artworks of males, females and variations, as well as close-ups of important characters.
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.
This volume contains a complete set of distribution maps, and information on all the resident and more frequent immigration dragonflies in Britain and Ireland. It takes a look at the present and changing status of dragonfly species, provides insight into their distribution, gives descriptions to aid recognition, and summarizes aspects of behaviour and details of habitat. The information for the atlas comes from the Recording Scheme set up at the Biological Records Centre 25 years ago which, apart from deepening our understanding of dragonflies, has focused attention on the need for conservation measures. This book includes important and notable discoveries made in the course of the research, and provides a history of conservation in Britain and Ireland and the context and rationale for future efforts. It is a book which should be of interest not only to amateur naturalists and fieldworkers but also students and professional biologists.
La 4e de couverture indique: "Europe's Dragonflies is a comprehensive, lavishly illustrated and beautifully designed photographic field guide to the damselflies and dragonflies of Europe. Written by two well-travelled experts, the book covers all 140 resident and vagrant species recorded, focussing on the field identification of adult insects. Concise species profiles highlight key identification features and provide information on behaviour, habitat preferences, distribution, flight periods, status and conservation. Other sections cover identification tips, conservation status and legislation. Presenting an unsurpassed selection of images of the highest quality, this is the go-to guide for anyone wishing to know more about these amazing and fascinating insects."
Dragonflies and damselflies are some of the most beautiful, fragile and resilient insects found in the natural world. With their complex behaviours, astonishing aerobatic skills and preference for freshwater habitats, they are a very rewarding group of animals to observe in the field. Dragonflies and Damselflies of Britain and Western Europe features all 98 species found in the region. Packed with outstanding photography, this comprehensive book includes close-up illustrations to highlight key identification features, diagrams of wing venation, and detailed guides to dragonfly larvae and exuviae. Each species account includes an accurate distribution map and information on field characteristics, confusion species, habitat and ecology. An introduction to the life cycle of Odonata, guidance on when and where to look for them, and the best ways to observe and photograph dragonflies and damselflies in the field are also included. These sections, combined with the identification guides, make this book the ultimate resource for any field naturalist or entomologist interested in these incredible insects.
Dragonflies and Damselflies 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 have been crucial to the advancement of our understanding of insect ecology and evolution. This book provides a critical summary of the major advances in these fields. Contributions from many of the leading researchers in dragonfly biology offer new perspectives and paradigms as well as additional, unpublished, data. The editor has carefully assembled a mix of theoretical and applied chapters (including those addressing conservation and monitoring) and achieves a balance of emerging and established research topics, providing suggestions for future study in each case. This accessible text is not about dragonflies per se but an essential source of knowledge that describes how different sets of evolutionary and ecological principles/ideas have been tested on a particular taxon. It will therefore be suitable for graduate students and researchers in entomology, evolutionary biology, population and behavioural ecology, and conservation biology. It will of course be of particular interest and use to those working on insects and an indispensable reference text for odonate biologists.
