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.
The Braconidae are a family of parasitoid wasps. After the closely related Ichneumonidae, braconids make up the second-largest family in the order Hymenoptera, with about 17,000 recognized species and many thousands more undescribed. One analysis estimated a total between 30,000 and 50,000, and another provided a narrower estimate between 42,000 and 43,000 species.
Pimplinae are a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Anomaloninae is a subfamily of parasitoid wasps in the family Ichneumonidae. Several species provide beneficial services to humans by attacking forest or orchard pests.
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.
Diadegma insulare is a wasp first described by Ezra Townsend Cresson in 1865. No subspecies are listed. It is a parasitoid of the diamondback moth, which is a pest of cruciferous crops.
Diadegma compressum is a wasp first described by Cresson in 1864. No subspecies are listed.
Anomalon cruentatum is a species of parasitoid wasps belonging to the family Ichneumonidae.
Tromatobia is a genus of ichneumon wasps in the family Ichneumonidae. There are at least 4 described species in Tromatobia. Species in this genus are parasites of egg sacs of spiders from the families Araneidae, Clubionidae, Philodromidae and Theridiidae.
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.
Netelia is a genus of ichneumonid wasps in the subfamily Tryphoninae. There are over 330 described species in Netelia grouped into 12 subgenera.
Polytribax is a genus of ichneumon wasps in the family Ichneumonidae. There are about 15 described species in Polytribax.
Therion is a genus of ichneumon wasps in the family Ichneumonidae. There are at least 20 described species in Therion.
Triclistus is a genus of ichneumon wasps in the family Ichneumonidae. There are at least 90 described species in Triclistus.
Bathythrix is a genus of ichneumon wasps in the family Ichneumonidae. There are at least 60 described species in Bathythrix.
Diplazon is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Habronyx is a genus of parasitoid wasps belonging to the family Ichneumonidae. The species of this genus are found in Europe, Australia, and North and South America.
Dusona is a genus of parasitoid wasps belonging to the family Ichneumonidae. It is the most species rich genus of the subfamily Campopleginae with 442 known species.
Habronyx fulvipes is a species of parasitic ichneumon wasp. It was renamed by Townes, Momoi and Townes in 1965 ; prior to that the species had been named Habronyx chinensis, chinensis meaning "China", in 1955 by Japanese entomologist Toichi Uchida. The holotype and allotype were collected by R. Mell. The species was first named Exochilum Chinense by Morley in 1913.
