This volume deals with the taxonomy and biology of the Dryinidae and Embolemidae (Hymenoptera: Chrysidoidea) of Fennoscandia and Denmark. These are parasitoids of leafhoppers and planthoppers (Homoptera Auchenorrhyncha).
The first part of the book examines general aspects of morphology, biology, natural enemies, economic importance, fossils, evolution and affinities. The second part deals with the classification of the species living in Fennoscandia and Denmark, with keys, descriptions, geographic distribution, hosts and bionomics.
The knowledge of the taxonomy and biology of the Dryinidae is important for biological control projects. The book is finely illustrated with 60 original drawings and 32 watercolours.
