Scolebythidae wasps are gregariousectoparasitoids of wood-boring beetle larvae. Females dig tunnels through the frass of wood-boring beetles using their mandibles. After reaching the host chamber of the beetle larva, frass is pulled into the chamber before stinging the larva. The female wasp feeds on the hemolymph after biting the integument. This behaviour is probably necessary for the ovipositing of eggs .
