Distribution Worldwide.
Biology Parasitoids of homopteran nymphs and adults (Cicadellidae, Delphacidae and Flatidae most commonly parasitized out of a total of 12 families). Adult female dryinids usually have a chelate foretarsus for grasping the host bug during oviposition. The Dryinid larva initially develops inside the host, but then extrudes in a characteristic sac that bulges out of the host's abdomen. Pupation occurs on the host food plant or in the soil.
Diversity 1100 species.
