The Ichneumonidae, also known as ichneumon wasps, ichneumonid wasps, ichneumonids, or Darwin wasps, are a family of parasitoid wasps of the insect order Hymenoptera. They are one of the most diverse groups within the Hymenoptera with roughly 25,000 species described as of 2016. However, this likely represents less than a quarter of their true richness as reliable estimates are lacking, along with much of the most basic knowledge about their ecology, distribution, and evolution. It is estimated that there are more species in this family than there are species of birds and mammals combined. Ichneumonid wasps, with very few exceptions, attack the immature stages of holometabolous insects and spiders, eventually killing their hosts. They thus fulfill an important role as regulators of insect populations, both in natural and semi-natural systems, making them promising agents for biological control.
Cryptinae is a subfamily of wasps in the family Ichneumonidae. The family has also been called Gelinae, Hemitelinae, and Phygadeuontinae by various authorities, though the Phygadeuontinae have since been elevated to a separate subfamily.
Acaenitinae is a subfamily of the parasitoid wasp family Ichneumonidae. Female Acaenitinae have a large triangular projecting genital plate.
In this checklist are presented all wasp species of family Ichneumonidae found within the UK.
Gerd Hermann Heinrich was a German entomologist and ornithologist known for his studies of parasitic Hymenoptera of the Ichneumonidae family and for the description of several bird species in Celebes, Dutch East Indies.
Agrothereutes abbreviatus is a species of parasitic wasp belonging to the family Ichneumonidae.
Cratichneumon coruscator is a species of the parasitic wasp family Ichneumonidae.
Trogus is a genus of parasitoid wasp found in the Holarctic and Neotropic regions. It is placed in the subfamily Ichneumoninae and the tribe Ichneumonini. Trogus species are parasites of larvae and pupae of the swallowtail butterfly family, Papilionidae. The genus consists of twelve extant and one extinct species.
Vulgichneumon is a genus of ichneumon wasps in the family Ichneumonidae. There are at least 30 described species in Vulgichneumon.
Dolichomitus is a genus of ichneumon wasps in the family Ichneumonidae. There are at least 70 described species in Dolichomitus. The name is derived from the Greek dolicho, meaning long or narrow, and the Greek mitus, meaning a thread.
Aptesis is a genus of parasitoid wasps belonging to the family Ichneumonidae. The genus was first described by Arnold Förster in 1850 and has almost cosmopolitan distribution.
Hoplismenus is a genus of parasitoid wasps belonging to the family Ichneumonidae.

Platylabini is a tribe of ichneumon wasps in the family Ichneumonidae. There are at least 40 genera and about 8 described species in Platylabini.
Listrodromus nycthemerus, the holly blue Darwin wasp, is a species of ichneumon wasp belonging to the family Ichneumonidae. This species is a parasitoid, its sole host species being the holly blue butterfly.
Listrodromus is a genus of ichneumon wasps belonging to the family Ichneumonidae. These wasps are parasitoids of butterflies of the family Lycaenidae, laying eggs in the caterpillars.
