Evania appendigaster (Linnaeus, 1758).

Evania peringueyi Cameron, 1906. Holotype in NHMUK, London. Type locality: Cape Colony, Cape Town, South Africa.

Classification

Distribution

Probably originally an Oriental species, but now widespread throughout tropical and temperate countries. Afrotropical region: probably all countries. Also in Neacrtic and Neotropical regions.

Biology

Parasitoid of cockroach eggs, particularly those of the American cockroach Periplaneta americana and the Oriental cockroach (Blattella orientalis). Female penetrates tough cockroach egg case with her ovipositor and lays a single egg inside. Larva eats cockroach eggs and pupates inside the case. On emerging from the pupa, adult wasp chews an exit hole in the side of the case. Adults occasionally found inside homes and buildings.
