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 This book is unusual in combining synthetic reviews and new, unpublished data with original ideas.

The diversity of social behavior among birds and primates is surpassed only by members of the Hymenopteran insects, including bees, ants, and the genus Polistes, or paper-wasps. This volume combines incisive reviews and new, unpublished data in studies of paper-wasps, a large and varied group whose life patterns are often studied by biologists interested in social evolution. While this research is significant to the natural history of paper-wasps, it also applies to topics of general interest such as the evolution of cooperation, social parasitism, kin recognition, and the division of labor.

The editors have used the specific conditions of Proceedings to great advantage: they retained the interesting speculations that might not be accepted in a journal. The wealth of stimulating hypotheses will certainly provoke new directions of research not only in the study of polistine wasps, but social insects in general.
