Biology:Chrysidoidea

From HandWiki

The superfamily Chrysidoidea is a very large cosmopolitan group, all of which are parasitoids or cleptoparasites of other insects.[1] There are three large, common families (Bethylidae, Chrysididae, and Dryinidae) and four small, rare families (Embolemidae, Plumariidae, Sclerogibbidae, and Scolebythidae).[2] This superfamily is traditionally considered to be the basal taxon within the Aculeata, and, as such, only a few species can sting.[2] Most wasps in the family are under 3mm in length.[1]

Members of the families Dryinidae and Embolemidae are the only parasitoids among the Hymenoptera to have a life cycle in which the wasp larva begins its life inside the body of the host, and then later forms a sac (called a thylacium) that protrudes out of the host's abdomen.[3] The closely related family Sclerogibbidae contains more traditional ectoparasitoids, attacking the nymphs and adults of webspinners.[2]

The extinct, monotypic family Plumalexiidae was described in 2011 from fossils preserved in Turonian age New Jersey amber.[4]
