Scelio opacus
Scelio opacus is a species of parasitoid wasp in the family Scelionidae, first described by Provancher in 1887. Members of the genus Scelio are known to parasitize the eggs of grasshoppers and related orthopterans. The species belongs to a group of small wasps, typically measuring 3–10 mm in length, that often exhibit the black-orange-black (BOB) color pattern common among scelionids. Like other Scelioninae, this species likely plays a role in regulating orthopteran populations through egg parasitism.
