Distribution	Worldwide.
Biology	Platygastrinae are mostly koinobiont parasitoids of gall midge (Cecidomyiidae) eggs developing only after host has reached pupal or prepupal stage. Some are idiobiont parasiotoids of beetle (Coleoptera) or bug (Homoptera) eggs, or Coccoidea or Aleyrodidae larva. Scelioninae, Teleasinae and Telenominae are idiobiont endoparasitoids of insect and spider eggs.
Diversity	4200 described species.
