Ichneumon nyassae is a species of wasp in the genus Ichneumon .
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species, it is a piercing organ as well.
The superfamily Ichneumonoidea contains one extinct and three extant families, including the two largest families within Hymenoptera: Ichneumonidae and Braconidae. The group is thought to contain as many as 100,000 species, many of which have not yet been described. Like other parasitoid wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, now known to be paraphyletic.
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.
Tolonus is a genus of ichneumon wasps in the subfamily Cryptinae.
Megarhyssa, also known as giant ichneumonid wasps, giant ichneumons, or stump stabbers, is a genus of large ichneumon wasps, with some species known for having the longest ovipositors of any insects. They are idiobiont endoparasitoids of the larvae of wood-boring horntail wasps. The ovipositor can be mistaken for a large stinger. This is a genus of holometabolous insects within subfamily Rhyssinae that includes 37 species and belongs to Ichneumonidae, the family of wasps with the highest biodiversity in the world.

In the 10th edition of Systema Naturae, Carl Linnaeus classified the arthropods, including insects, arachnids and crustaceans, among his class "Insecta". Insects with membranous wings, including bees, wasps and ants were brought together under the name Hymenoptera.
Rhyssa persuasoria, also known as the sabre wasp, is a species belonging to the family Ichneumonidae subfamily Rhyssinae. Members of this subfamily, including those of Rhyssa and the allied Megarhyssa, are also known collectively as giant ichneumonid wasps or giant ichneumons.
Echthromorpha intricatoria, also known as the cream-spotted ichneumon, is a common wasp found in Australia and New Zealand. It cannot sting and does not build nests, and is harmless to humans. The female injects eggs into pupae of moths and butterflies with the ovipositor, particularly favouring the Nymphalidae. Metacrias huttoni has been shown to be a host species for E. intricatoria.
Ichneumon is a genus of parasitoid wasps in the family Ichneumonidae.
Diadegma chrysostictos is a wasp first described by J.F. Gmelin in 1790. No subspecies are listed.
Amblyteles armatorius is a species of parasitic wasp in the family Ichneumonidae first described by Johann Reinhold Forster in 1771.
Xanthopimpla punctata, also known as the yellow ichneumon wasp, is a yellow-colored Ichneumon wasp of subfamily Pimplinae. Xanthopimpla spp. play a beneficial role in agriculture. They are important parasitoids of lepidopterous stem borers of cereals, sugar cane and other crops; they lay their eggs on moth caterpillars that damage crops.
Ichneumon sarcitorius is a species of wasp belonging to the family Ichneumonidae subfamily Ichneumoninae.
Ichneumon rubriornatus is a species of wasp in the genus Ichneumon. It was described by Peter Cameron in 1904.
Ichneumon tottor is a species of wasp in the genus Ichneumon. It is endemic to South Africa.
Ichneumon unicinctus is a species of wasp in the genus Ichneumon. It is endemic to Madagascar, Mauritius and Réunion.
Megarhyssa macrurus, also known as the long-tailed giant ichneumonid wasp or long-tailed giant ichneumon wasp, is a species of large ichneumon wasp. It is a parasitoid, notable for its extremely long ovipositor which it uses to deposit an egg into a tunnel in dead wood bored by its host, the larva of a similarly large species of horntail.
Ichneumon eumerus is a species of parasitic wasp belonging to the family Ichneumonidae, subfamily Ichneumoninae. It is a specialist parasite of the larva of the mountain Alcon blue butterfly.
Ian D. Gauld (1947–2009) was a British entomologist who specialised in the study of parasitic ichneumon wasps. According to his obituary, he is the most prolific ichneumon taxonomist in history, describing over 2000 species of ichneumonids.
