Fly-parasitoid
Guides
Aleochara
Aleochara is a genus of rove beetles (Staphylinidae) distinguished by its parasitoid larval life history. Adults are predatory, feeding on eggs, larvae, and puparia of scatophagous and necrophagous Diptera. Larvae are ectoparasitoids that develop inside fly puparia, killing the host. The genus contains at least 150 and possibly more than 400 species across 16 subgenera, with a worldwide distribution except Antarctica. Several species, notably Aleochara bilineata, are significant biological control agents of agricultural pest flies.
Spalangiidae
Spalangiidae is a family of chalcid wasps (Hymenoptera: Chalcidoidea) elevated from former subfamilies of Pteromalidae in 2022. Members are parasitoids of flies, with two recognized subfamilies: Spalangiinae and Erotolepsiinae. The family is now classified within the planidial clade, more closely related to Eucharitidae, Perilampidae, Chrysolampidae, and Eutrichosomatidae than to core Pteromalidae. The genus Spalangia has a cosmopolitan distribution, while other genera show restricted geographic ranges.
