A lavishly illustrated introduction to the world's dragonflies and damselflies Dragonflies and damselflies are often called birdwatchers' insects. Large, brightly colored, active in the daytime, and displaying complex and interesting behaviors, they have existed since the days of the dinosaurs, and they continue to flourish. Their ancestors were the biggest insects ever, and they still impress us with their size, the largest bigger than a small hummingbird. There are more than 6,000 odonate species known at present, and you need only visit any wetland on a warm summer day to be enthralled by their stunning colors and fascinating behavior. In this lavishly illustrated natural history, leading dragonfly expert Dennis Paulson offers a comprehensive, accessible, and appealing introduction to the world's dragonflies and damselflies. The book highlights the impressive skills and abilities of dragonflies and damselflies--superb fliers that can glide, hover, cruise, and capture prey on the wing. It also describes their arsenal of tactics to avoid predators, and their amazing sex life, including dazzling courtship displays, aerial mating, sperm displacement, mate guarding, and male mimicry. Dragonflies and Damselflies includes profiles of more than fifty of the most interesting and beautiful species from around the world. Learn about the Great Cascade Damsel, which breeds only at waterfalls, the mesmerizing flight of Blue-winged Helicopters, and how the larva of the Common Sanddragon can burrow into sand as efficiently as a mole. Combining expert text and excellent color photographs, this is a must-have guide to these remarkable insects. A lavishly illustrated, comprehensive, and accessible natural history that reveals the beauty and diversity of one of the world's oldest and most popular insect groups Offers a complete guide to the evolution, life cycles, biology, anatomy, behavior, and habitats of dragonflies and damselflies Introduces the 39 families of dragonflies and damselflies through exemplary species accounts Features tips on field observation and lab research, and information on threats and conservation

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.
