Cratichneumon vinnulus
Cratichneumon vinnulus is a species of ichneumon wasp in the family Ichneumonidae, described by Cresson in 1864. It belongs to a large genus of parasitoid wasps whose members are primarily known for attacking Lepidoptera larvae. Like other members of Cratichneumon, this species likely functions as a koinobiont parasitoid, allowing its host to continue developing after oviposition. The species has been documented in North America, though specific ecological details remain poorly recorded.
Cratichneumon w-album
Cratichneumon w-album is a species of ichneumon wasp in the family Ichneumonidae, first described by Cresson in 1864. The species name refers to the distinctive white 'W'-shaped marking on the forewings. It is a moderately-sized parasitoid wasp with documented observations across eastern North America.
Trogus flavipennis
Trogus flavipennis is a species of ichneumon wasp described by Ezra Townsend Cresson in 1864. It belongs to the large family Ichneumonidae, one of the most diverse families within Hymenoptera. The genus Trogus comprises parasitoid wasps that attack lepidopteran hosts. The specific epithet "flavipennis" refers to yellowish wing coloration. Available records for this species are sparse, with limited observational data documented in biodiversity databases.
