Apparently, females have an excrutiating sting. Abstract Bethylid wasps are a medium sized family of parasitic Hymenoptera, with biological control potential, which have recently proved excellent model systems for testing evolutionary and life history theory. Laelius is a genus of hymenopteran parasitoids in the family Bethylidae.
