This definitive handbook provides an in-depth treatment of insect morphology. The up-to-date overview of insect morphology is complemented by a chapter on innovative morphological techniques (e.g., µ-computer tomography, 3-D modeling) and a comprehensive morphological glossary. The second part treats the state of the art in insect systematics and includes taxon-specific morphological information for all orders. The work is a useful reference for students and researchers working in different fields of biology and a must for those dealing with insects from an evolutionary perspective.
