RES Handbook Vol 7 Part 1. Hymenoptera - Ichneumonoidea (Pimplinae)

The subfamily Pimplinae is biologically the most diverse, and probably the most extensively studied, within the Ichneumonidae. In the British Isles there are 108 species , representing 37 genera. Worldwide the subfamily comprises about 77 genera . The majority of pimplines are ectoparasitoids of immature Lepidoptera , Coleoptera, Hymenoptera, Diptera or Arachnida, while some are pseudoparasitoids of spider egg sacs, and one group are endoparasitoids in endopterygote pupae and prepupae . Several species are hyperparasitic, often facultatively, and a few are cleptoparasitic on other pimplines. Many of the genera include species of economic importance . Indeed , it is partly because many species are parasitoids of pests that so much (in comparison with other ichneumonids) is known about the biology of the group.
