Parasitic biology

This wasp is a parasitoid on scarabaeid beetle larvae (recorded hosts include Aphodius, Rhizotrogus and Anisoplia). The female burrows into the soil to find a larval host (usually well matured) in its cell. The wasp burrows below the host's cell before breaking into it, where she stings the larva and kneads it with her mandibles. An egg is laid usually on the lateral or ventral surface of the host in a fold of the cuticle. The paralysis is temporary, lasting for about 20-40 minutes, after which the larva becomes active, usually sufficiently so to continue feeding on the roots of grass. The wasp egg hatches to produce a larva which takes about three weeks to consume its host. At first the ectoparasitoid sucks the haemolymph before finally entering the host and eating the viscera. Pupation takes place in the host's cell.
