The book provides a comprehensive study of the North American species of Apanteles, a genus of parasitic wasps that are important natural enemies of many agricultural pests. The book includes detailed descriptions of the morphology, taxonomy, and distribution of the species, as well as information on their biology, behavior, and ecology. The author also provides keys for the identification of the species, which are illustrated with detailed drawings and photographs.
