Commonly known as cuckoo wasps, the Hymenopteran family Chrysididae is a very large cosmopolitan group (over 3000 described species) of parasitoid or cleptoparasitic wasps, often highly sculptured, with brilliantly metallic bodies and bright coloration (thus the common names jewel wasp, gold wasp, or emerald wasp are sometimes used). They are most diverse in desert regions of the world, as they are typically associated with solitary bee and wasp species, which are also most diverse in such areas.
Members of the largest subfamily, Chrysidinae, are the most familiar; they are generally cleptoparasites, laying their eggs in host nests, where their larvae consume the host egg or larva while it is still young, then consuming the provisions. Other subfamilies are parasitoids, of either sawflies or walking sticks.
