Synthesizing some 150 years of research, this is the only book to cover the biology and behavioral ecology of tent caterpillars. Terence D. Fitzgerald discusses the systematics, distribution, and host range of North American and Eurasian species of tent caterpillars. He then considers the anatomy and physiology of the egg, larva, pupa, and adult, with particular emphasis on sensory physiology, silk production, reproductive behavior, overwintering adaptations, and the energetics of adult and larva locomotion.
