Sawflies are wasp-like insects that are in the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. The name is associated especially with the Tenthredinoidea, by far the largest superfamily in the suborder, with about 7,000 known species; in the entire suborder, there are 8,000 described species in more than 800 genera. Symphyta is paraphyletic, consisting of several basal groups within the order Hymenoptera, each one rooted inside the previous group, ending with the Apocrita which are not sawflies.
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 play an important role as regulators of insect populations, both in natural and semi-natural systems, making them promising agents for biological control.
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.
Acaenitinae is a subfamily of the parasitoid wasp family Ichneumonidae. Female Acaenitinae have a large triangular projecting genital plate.
The Labeninae is a subfamily within the parasitoid wasp family Ichneumonidae. The family is divided into 12 extant genera grouped within four tribes.
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.
Rhyssinae is a subfamily of parasitoid wasps in the family Ichneumonidae. It contains eight genera and 259 described species, but there are likely many undiscovered species.
Acrotaphus is a genus of ichneumon wasps in the family Ichneumonidae. There are about 26 described species in Acrotaphus. They are parasitoids of Araneidae and Tetragnathidae spider families.
2015 in paleoentomology is a list of new fossil insect taxa that were described during the year 2015, as well as other significant discoveries and events related to paleoentomology that were scheduled to occur during the year.
Agrypon is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Agriotypus is a genus of insect belonging to the family Ichneumonidae first described by John Curtis in 1832.
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.
Allomacrus is a genus of parasitoid wasps belonging to the family Ichneumonidae.
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.
