Ichneumonid Wasps (Hymenoptera Ichneumonidae): their Classification and Biology

An extensively illustrated key is provided for the identification of the 35 subfamilies of Ichneumonidae known to occur in Britain and Ireland (plus Brachycyrtinae, not yet found here). This is supported by chapters for each subfamily (completed by briefer accounts of extralimital ones, in order to cover the entire world ichneumonid fauna), giving a comprehensive review of current knowledge on systematics, biology and host relations together with notes on useful recognition features and references to the most relevant species-level identification literature concerning the British Isles. Included in each British and Irish subfamily account is a folio of photographs covering all recognised tribes. Also given are an illustrated scheme for preferred morphological terminology, with cross referencing to more archaic schemes that have been used in some of the recommended identification literature on Ichneumonidae, a list of ichneumonid genera found in Britain and Ireland, and an extensive glossary of both morphological and biological terms.
