Proctotrypidae[1] Proctotrupidae is a family of parasitic wasps in the superfamily Proctotrupoidea.

There are about 400 species in more than 30 genera in Proctotrupidae, found throughout most of the world.

[2][1] Proctotrupidae are small parasitoid wasps, that primarily parasitise larvae of beetles belonging to the families Carabidae, Staphylinidae, and Elateridae, though a number of species are known to target other hosts, including fungus gnats (Mycetophilidae, Sciaridae) and concealer moths.

[3] Females in many species are wingless and dwell in the soil, where they are capable of detecting beetle larvae in their burrows.
