Social behavior occurs in some of the smallest animals as well as some the largest, and the transition from solitary life to sociality is an unsolved evolutionary mystery. In The Evolution of Social Wasps, James H. Hunt examines social behavior in a single lineage of insects, wasps of the family Vespidae. He presents empirical knowledge of social wasps from two approaches, one that focuses on phylogeny and life history and one that focuses on individual ontogeny, colony development, and population dynamics. He also provides an extensive summary of the existing literature while demonstrating how it can be clouded by theory. Hunt's fresh approach to the conflicting literature on sociality highlights how oft repeated models can become fixed in the thinking of the scientific community. Instead, Hunt presents a mechanistic scenario for the evolution of sociality in wasps that changes our perspective on kin selection, the paradigm that has dominated thinking about social evolution since the 1970s. This innovative new model integrates life history, nutrition, fitness and ecology in which social insect biologists will find a rich storehouse of ideas and information, and behavioral ecologists will find a bracing challenge to long accepted models. Engagingly written, bold, and provocative, The Evolution of Social Wasps marks a milestone in our understanding of one of lifes major evolutionary transitions - the origin of social behavior.

In this edited collection, 17 internationally known authorities bring together the results of recent research on the natural history, ecology, behavior, morphology, and genetics of wasps as they pertain to the evolution of social behavior. The first part of the book opens with a review of the classification of the family Vespidae along with a revision of the subfamily Polistinae. Seven subsequent chapters deal with the natural history and social biology of each of the major taxa of social and presocial vespids. The second part of the book offers chapters on reproductive competition; worker polyethism; evolution of nest architecture, of queen number and queen control, and of exocrine glands; population genetics; the nutritional bsis of social evolution; and the nest as the locus of social life. The final chapter is a comparative discussion of social behavior in the Sphecidae, the only family of wasps besides the Vespidae in which well-developed social behavior is known. Providing a wealth of information about the biology of wasps, this comprehensive, up-to-date volume will be an essential reference for entomologists, evolutionary biologists, behavioral ecologists, ethologists, and zoologists.

With over 400 pages and 900 full-color illustrations, The Social Wasps of North America is the world's first complete illustrated field guide to all known species of social wasps from the high arctic of Greenland and Alaska to the tropical forests of Panama and Grenada. For beginners, experts, and everyone in-between, The Social Wasps of North America provides new insights about some of the world’s least popular beneficial insects, plus tips and tricks to avoid painful stings. This book includes detailed information about the ecology, evolution, taxonomy, anatomy, nest architecture, and conservation of social wasp species.

'Social' insects and arachnids exhibit complex forms of behavior that involve cooperation in building a nest, defending against attackers or rearing offspring. This book is a comprehensive, up-to-date guide to sociality and its evolution in a wide range of taxa.

In this book, Ito presents data on tropical wasps which suggest that kin-selection has been overemphasized as an evolutionary explanation of sociality. He concentrates on the Vespidae (paper wasps and hornets), a group much discussed by evolutionary biologists because it exhibits all stages of social evolution:; subsociality, primitive eusociality, and advanced eusociality. The author reports field observations by himself and others in Central America, Asia, and Australia, showing that multiple egg-layers in a nest are not uncommon. Because coexistence of many `queens' leads to lower relatedness among colony members than in single-queen colonies, he suggests that kin-selection may not be the most powerful force determining observed social patterns. Instead, subsocial wasps may first have aggregated for defence purposes in habitats with a high risk of predation, with mutualistic associations among many queens. Through parental manipulation and then kin selection, differentiation into within-generation castes may have followed. Of interest to all students of ecology, evolution, and behaviour, this book beautifully illustrates the ability to combine wide-ranging data with thoughtful questions - the author's trademark.

Originally published in 1928, this volume, by a world authority on the subject, sums up our knowledge of the social insects. It inquires what are the social insects and what it is that makes us call them ‘social’. Terebrantia, aculeata, wasps, bees, ants, and termites are discussed in a succession of chapters, showing how they have evolved, to how great an extent they have developed, and what are the peculiarities of their evolution. Polymorphism, the Social Medium, Guests and Parasites of the Social Insects, are other subjects discussed in this fascinating book.

How can the stunning diversity of social systems and behaviours seen in nature be explained? Drawing on social evolution theory, experimental evidence and studies conducted in the field, this book outlines the fundamental principles of social evolution underlying this phenomenal richness.To succeed in the competition for resources, organisms may either 'race' to be quicker than others, 'fight' for privileged access, or 'share' their efforts and gains. The authors show how the ecology and intrinsic attributes of organisms select for each of these strategies, and how a handful of straightforward concepts explain the evolution of successful decision rules in behavioural interactions, whether among members of the same or different species. With a broad focus ranging from microorganisms to humans, this is the first book to provide students and researchers with a comprehensive account of the evolution of sociality by natural selection.

Darwin famously described special difficulties in explaining social evolution in insects. More than a century later, the evolution of sociality - defined broadly as cooperative group living - remains one of the most intriguing problems in biology. Providing a unique perspective on the study of social evolution, this volume synthesizes the features of animal social life across the principle taxonomic groups in which sociality has evolved. The chapters explore sociality in a range of species, from ants to primates, highlighting key natural and life history data and providing a comparative view across animal societies. In establishing a single framework for a common, trait-based approach towards social synthesis, this volume will enable graduate students and investigators new to the field to systematically compare taxonomic groups and reinvigorate comparative approaches to studying animal social evolution.

The diversity of social behaviour among birds and primates is surpassed only by members of the Hymenopteran insects (bees, ants, and wasps). The paper-wasps are a large and varied group, and have been studied extensively by a wide range of biologists interested in the evolution of sociality. This book is unusual in combining synthetic reviews and new, unpublished data with original ideas.
