Dragonflies & Damselflies are often called birdwatchers' insects. They are large, brightly coloured, active in the daytime, and with complex and interesting behaviour. Like butterflies, they appeal even to people who don't think highly of insects in general. They have been with us since the dinosaurs lived, and they continue to flourish. Their ancestors were the biggest insects ever, and they still impress us with their size-the largest is bigger than a small hummingbird. There are over 6,000 species of Odonata known at present, and you need only to visit any wetland on a warm summer day to be enthralled by their bright colours and fascinating behaviour.
This book "Dragonflies & Damselflies" brings dragonflies and damselflies to life, providing a broad introduction to their natural history and highlighting their remarkable skills and abilities. Dragonflies and damselflies are superb fliers that can glide, hover, cruise and capture prey on the wing. They also have an arsenal of tactics to avoid predators and an amzing sex life, including dazzling coutship displays, aerial mating, sperm displacement, mate guarding and male mimicry.
Dragonflies & 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.
