Horismenus fraternus
Horismenus fraternus is a species of chalcid wasp in the family Eulophidae, first described by Fitch in 1856. The genus Horismenus comprises small parasitoid wasps that develop within the bodies of other insects. Records indicate this species occurs in eastern Canada, specifically Ontario and Quebec. Like other eulophids, it likely functions as a parasitoid of insect hosts, though specific biological details remain poorly documented.
