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.
