Ensign wasp

Evania appendigaster is a species of ensign wasp, a family of parasitoid wasps whose larvae are known to be predatory on cockroaches. However, hosts for 96% of the over 400 species are not yet known, so it is likely that more unusual life histories exist. Ensign wasps are found worldwide, apart from the polar regions.
