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.
Acaenitinae is a subfamily of the parasitoid wasp family Ichneumonidae. Female Acaenitinae have a large triangular projecting genital plate.
Campopleginae is a large subfamily of the parasitoid wasp family Ichneumonidae with a world-wide distribution. Species in this subfamily have been used in the biological control of the alfalfa weevil, clover weevil, various species of Heliothis, oriental army worm, European corn borer, larch sawfly, and others.
Tersilochinae is a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Allophrys is a genus of the parasitic wasp family Ichneumonidae.
Diadegma callisto is a wasp first described by Horstmann in 1993. No subspecies are listed.
Agrothereutes is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Cymodusa is a genus of parasitoid wasps in the family Ichneumonidae.
Hellwigia is a genus of ichneumon wasps. A specimin of the species was reared by scientists for the first time in the Netherlands.
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.
Dumbea is a genus of leaf beetles in the subfamily Eumolpinae. It is known from the South Province and Mont Panié of New Caledonia, and is named after Dumbéa, a town nearby Nouméa. This name was originally used by the French entomologist Charles Adolphe Albert Fauvel to house several species of Eumolpinae from New Caledonia, but Fauvel's Dumbea was unpublished and is a nomen nudum. The genus was established based on general proportions and body size, and may be polyphyletic or paraphyletic.
Erzsébet Némethné Bajári and published as Erzsébet N. Bajári; (1912–1963) was a Hungarian entomologist, specifically a wasp researcher.
Barycnemis is a genus of parasitoid wasps belonging to the family Ichneumonidae. Host species include the genera Byrrhus, Bledius, and Pissodes.
Campoletis is a genus of parasitoid wasps belonging to the family Ichneumonidae.

Allomacrus is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Bruchidius nalandus, is a species of leaf beetle found in Congo, India, Indonesia, Iran, Kenya, South Africa, Sri Lanka, United Arab Emirates, Vietnam and Socotra Island.
Dusona falcator is a large species of parasitic wasp belonging to the family Ichneumonidae, subfamily Campopleginae. It is a parasitoid of the buff-tip moth. It is one of the largest known species of Camopleginae, able to reach sizes over 20mm. The species can be found throughout the Palearctic realm.
Callidora is a genus of parasitoid wasps belonging to the family Ichneumonidae and the subfamily Campopleginae. It is relatively species poor, with only five recognized species.
