Habronyx is a genus of parasitoid wasps belonging to the family Ichneumonidae. [1] The species of this genus are found in Europe, Australia, and North [1] and South America. [2]
Habronyx species are found in most realms, with the exception of the Afrotropical realm. [2]
Habronyx adults lay their eggs inside Lepidopteran larvae (i.e. caterpillars) by piercing them with their ovipositor. [2] Habronyx eggs consist of an equatorial disc and a caudal stalk, making them look a bit like the cartoon oil lamp from Aladdin. [3] It's thought that the shape is adapted to attach the egg to the inside of the caterpillar's integument. [4] Once the eggs hatch, the Habronyx larvae consume the caterpillar from the inside. They emerge from the deceased caterpillar as adults.
The adult of most Habronyx species are generally about 30 mm (1.2 in) in length. [3]
Like all ichneumons, the genitals of the male Habronyx consists of a capsule formed by two lateral gonosquamae. The membraneous part of the aedeagus is covered in small spines; Habryonx shares this feature with several other genera but some genera have a smooth aedeagus. [3]
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.
Pimplinae are a worldwide subfamily of the parasitic wasp family Ichneumonidae.
Acaenitinae is a subfamily of the parasitoid wasp family Ichneumonidae. Female Acaenitinae have a large triangular projecting genital plate.
Anomaloninae is a subfamily of parasitoid wasps in the family Ichneumonidae. Several species provide beneficial services to humans by attacking forest or orchard pests.
Anomalon is a large genus of parasitoid wasps belonging to the family Ichneumonidae. This may be the only genus in the tribe Anomalonini, although Neogreeneia Viereck, 1912 is sometimes considered a valid genus of the tribe.
Netelia is a genus of ichneumonid wasps in the subfamily Tryphoninae. There are over 330 described species in Netelia grouped into 12 subgenera.
Triclistus is a genus of ichneumon wasps in the family Ichneumonidae. There are at least 90 described species in Triclistus.
Dolichomitus is a genus of ichneumon wasps in the family Ichneumonidae. There are at least 70 described species in Dolichomitus. The name is derived from the Greek dolicho, meaning long or narrow, and the Greek mitus, meaning a thread.
Gravenhorstiini is a large tribe of parasitoid wasps belonging to the family Ichneumonidae It contains all the genera of the subfamily Anomaloninae, excepting Anomalon.
Casinaria is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Heteropelma is a genus of parasitoid wasps belonging to the family Ichneumonidae. Species in this genus are around 25 mm in length.
Glypta is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Trichomma is a genus of parasitoid wasps belonging to the family Ichneumonidae.
Netelia producta is a species of ichneumonid wasp in the subfamily Tryphoninae found in Australia.
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.
Listrodromus is a genus of ichneumon wasps belonging to the family Ichneumonidae. These wasps are parasitoids of butterflies of the family Lycaenidae, laying eggs in the caterpillars.
