Comperia merceti

Comperia merceti (Encyrtidae) is only a couple millimeters long, but it has an outsized effect on cockroaches. Young wasps of this species develop inside cockroaches’ hardened egg cases, consuming the eggs. Like the vast majority of wasps, Comperia is not aggressive and does not sting. Laboratory colony at the University of Arizona.
