Cremastinae is a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Cremastinae are koinobiont endoparasitoids of Lepidoptera and, sometimes, Coleoptera larvae in tunnels, leaf rolls, buds and galls.
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.
Thomas Ansell Marshall was an English cleric and entomologist, mainly interested in Hymenoptera. He was the son of Thomas Marshall, one of the original members of the Royal Entomological Society of London.
Arnold Förster was a German entomologist, who worked mainly on Coleoptera and Hymenoptera.
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.
Banchinae is a subfamily of ichneumonid parasitoid wasps containing about 1,500 species; the genera Glypta and Lissonota are very large. The three tribes are all distributed worldwide.
Xoridinae are a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Pimplinae are a worldwide subfamily of the parasitic wasp family Ichneumonidae.
The Metopiinae are a worldwide subfamily of the parasitic wasp family Ichneumonidae. Metopiinae are koinobiont endoparasitoids of Lepidoptera. There are 26 extant genera. A bulging shield-like face is diagnostic for members of this subfamily, but many members lack this character.
Acaenitinae is a subfamily of the parasitic wasp family Ichneumonidae. It is distributed on all continents except Antarctica, although only one specimen (from the genus Arotes has ever been discovered in South America. Little is known of the Acaenitinae. The only reared species was a koinobiont endoparasitoid of a weevil. There are 24 genera. Hosts are believed to be Coleoptera larvae in wood. Female Acaenitinae have a large triangular projecting genital plate.
Ichneumoninae is a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Mesochorinae is a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Tersilochinae is a worldwide subfamily of the parasitic wasp family Ichneumonidae.
The Labeninae is a subfamily within the parasitoid wasp family Ichneumonidae. The family is divided into 12 extant genera grouped within four tribes.
Labenopimplinae are an extinct subfamily of the parasitic wasp family Ichneumonidae. Labenopimplinae are known from the Cenomanian of the Russian Far East and Turonian of Orapa, Botswana. The subfamily includes five genera with 13 species. The subfamily is highly polymorphic and combines features of the Labeninae and Pimplinae.
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.
Ichneumonini is a tribe of ichneumon wasps in the family Ichneumonidae. There are more than 350 genera and thousands of described species in Ichneumonini.
Netelia is a genus of ichneumonid wasps in the subfamily Tryphoninae. There are over 330 described species in Netelia grouped into 12 subgenera.
Henry Keith Townes, Jr. was an American entomologist who specialized in the Hymenoptera with a special focus on the Ichneumonidae.
Lathrolestes luteolator is a species of wasp in the family Ichneumonidae. it is native to North America and is a parasitoid of various species of sawfly larvae. In the 1990s, it started to parasitise the larvae of the invasive amber-marked birch leaf miner in Alberta. When this pest spread to Alaska, the wasp was used in biological pest control.
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.
