"Lively and lucid...To read this book is to enrich a summer's day and a winter's dreaming." --Howard E. Evans, Natural History"This is a remarkable and rewarding book, complementary to, yet in some respects going far beyond, its predecessors. It is highly recommended." --Caryl P. Haskins, New York Times Book Review"Extraordinary...the implications of work such as Heinrich's seem to me more resonant than the promise of a rich harvest of new research."    --Fred Hapgood, Harper's Magazine "A magnificent book that combines the best of both writing and science. The text is clearly and concisely written--a rare find in scientific communication. Virtually anyone, but particularly ecologists, evolutionists, and entomologists, will find this book enjoyable and fascinating reading...Bumblebee Economics describes the heterothermic strategies of bumblebees in considerable detail, with lucid discussions of thermoregulation and its behavioral application...Heinrich has performed a masterful job of sharing his personal research efforts and those of others in his field. He has written an extremely interesting book and in the process has shown how one kind of organism can be used as a model to investigate behavior, physiology, ecology and evolution. Bumblebee Economics should serve as a model for good scientific writing."    --Matthew M. Douglas, Quarterly Review of Biology
