Metopiinae
Guides
Colpotrochia
Colpotrochia is a genus of ichneumon wasps in the subfamily Metopiinae, containing at least 61 described species. These small wasps, averaging 6–10 mm in body length, are larval-pupal endoparasitoids of Lepidoptera. Females use a short ovipositor to lay eggs in caterpillars, with wasps emerging from the host pupa rather than the adult moth. The genus has been recorded from North America, Brazil, and Europe.
Colpotrochia texana
Colpotrochia texana is a small ichneumon wasp in the subfamily Metopiinae, first described by Cresson in 1872. It is one of four North American species in the genus Colpotrochia, which are koinobiont parasitoids of caterpillars. The species is known from Brazil (Santa Catarina and São Paulo states) based on distribution records, though the genus as a whole ranges from the Atlantic coast of North America to just west of the Mississippi River.
Colpotrochia trifasciata
A small ichneumon wasp in the subfamily Metopiinae, averaging 6-10 millimeters in body length. Females possess a very short ovipositor used to lay eggs in caterpillars, particularly leafrollers in the family Tortricidae. The wasp larva develops inside the host, consuming it without disrupting the caterpillar's life cycle until after it pupates; an adult wasp emerges from the host pupa rather than a moth. One of two Colpotrochia species recorded in Massachusetts, with a range extending from the Atlantic coast to barely west of the Mississippi River.
Exochus
Exochus is a large genus of ichneumon wasps in the subfamily Metopiinae, containing at least 270 described species. The genus was established by Gravenhorst in 1829. Species occur across multiple continents, with records from the Neotropical region including Brazil. Members are parasitoid wasps, though specific host associations remain poorly documented for most species.
Metopius
Metopius is a cosmopolitan genus of parasitoid wasps in the subfamily Metopiinae (Ichneumonidae). Adults are large, conspicuous insects with bold black and yellow longitudinal striping, reaching over 2 cm in length. The genus is divided into subgenera including Metopius s.str. and Peltastes. Species are known to parasitize caterpillars of Lepidoptera, particularly those found in leaf rolls.
Seticornuta
Seticornuta is a small genus of parasitoid wasps in the subfamily Metopiinae (Ichneumonidae). The genus contains approximately seven described species distributed across the Americas and Asia. Members are solitary larval or pupal koinobiont endoparasitoids of Lepidoptera. Recent descriptions include S. jacutinga from Brazil and S. koreana from South Korea, expanding the known range of this previously poorly documented genus.
Trieces
Trieces is a genus of parasitoid wasps in the family Ichneumonidae, subfamily Metopiinae. It is one of the largest genera within the Metopiinae, with species described from all zoogeographical regions except the Indomalayan region until recently. Species are solitary endoparasitoids of Lepidoptera. The genus includes multiple species groups, with the onitis group being particularly well-studied in the Nearctic region.
