This established and popular textbook is the definitive guide to the study of insects - a group of animals that represent over half of the planet's biological diversity. In this new, third edition the authors maintain the clear, concise approach of the previous editions, examining all aspects of insect biology. In addition to updating the whole text with the latest research, the third edition features: a new chapter on the methods and results of studies of insect phylogeny; a new review of insect evolution and biogeography; strategies in insect conservation, covered for the first time, reflecting the increasing threat to natural ecosystems from introduced species and environmental changes; and a review of the Mantophasmatodea - the first new order of insects described for many decades. Written in an accessible and stimulating style, the book includes boxes highlighting key themes, suggestions for further reading, and is extensively illustrated with specially commissioned drawings and color plates. This book is the ideal principal text for students taking courses in entomology and for wider degree courses in which the study of insects is important, such as ecology, agriculture, fisheries and forestry, paleontology, zoology, and medical and veterinary science.Cranston, Peter is the author of 'Insects An Outline of Entomology', published 2004 under ISBN 9781405111133 and ISBN 1405111135.
