The Chalcididae represent a large group of parasitic Hymenoptera which parasitise pupal or larval stages of various insects including several pests. Their phylogeny is not so far clearly known, but a Eurytomid—Torymid line of accent could be postulated. There is a general resemblance in their adult behaviour such as emergence, courtship, mating, oviposition, feeding etc. Their hosts belong to Lepidoptera, Diptera, Hymenoptera, Neuroptera, Coleoptera and Strepsiptera.
