Mengenillidae

Mengenillidae is a family of insects belonging to the order Strepsiptera. It is the second most basal member of the order, after Bahiaxenidae. Unlike members of Stylopidia, which contains the vast majority of strepsipterans, the adult females of the family are free-living with legs. Members of the family with known hosts (Eoxenos and Mengenilla) parasitise members of the family Lepismatidae (silverfish and kin).
