Maggiori informazioni sul libro
Dragonflies are increasing in popularity because they are colourful and fascinating to watch in flight over water. Their conservation in the British countryside has become a matter of concern. This book provides an introduction for those who wish to learn more about them, and will enable readers to undertake investigations of their own. Dragonflies are bird watchers' insects because most of the species can be recognised in flight. It is fascinating to watch the behaviour involved in feeding, defending a territory, mating and laying eggs. The acquatic larvae capture and eat acquatic animals, and some have been shown to defend underwater territories. This book introduces the natural history of dragonflies, and draws attention to topics suitable for further investigation. Keys are provided for the identification of both larvae and adults, and information is given on techniques for study. Some problems of conservation are discussed.
