Pteromalidae
Pteromalidae (jewel wasps; suborder Apocrita, superfamily Chalcidoidea) Family of minute (2–4 mm long), usually black or metallic green wasps, many of which are important in the control of crop pests. This large and abundant group has a complex taxonomy and is sometimes broken into several families. Jewel wasps are parasitic on a wide range of hosts, including ants, the larvae of Lepidoptera, Coleoptera, and Diptera, other chalcidoids, and the oothecae of cockroaches and spiders, while others are hyperparasites on the larvae of other parasitic wasps.
