Reviews

'Possessing these two handsomely produced volumes is like possessing Aladdin's magic lamp ...You may take your pick - from parental care in cockroaches to sex among cannibals in jumping spiders ... it's an endless menu!' Raghavendra Gadagkar, Trends in Ecology and Evolution 'Choe and Crespi have succeeded in providing an exceptional addition to the literature on social behavior in insects and arachnids. To my knowledge this book is the first of its kind to focus completely on the evolution of social systems in invertebrates ... a comprehensive volume that reviews the current literature and provides insightful new questions that probe the evolution of social behavior in insects and arachnids.' John Melville, Northwest Science '... an exceptional book packed with scholarship, insights and arthropod wonders ... fascinating ... splendidly thought provoking and hence in the best sense intellectually entertaining ... of considerable scientific value in terms of the breadth of its scope, the wealth of empirical findings and the careful evaluation of this ... so well written, skilfully packed with delightful examples that it should also be a source of pleasure to almost every ecological entomologist.'
