Dryinidae
Dryinidae (suborder Apocrita, super-family Bethyloidea) Family of small (1.5–10 mm long), black, parasitic wasps in which the fore tarsi of the female are often chelate and used to grasp the host adult or nymph. The host is stung and becomes insensible, whereupon the female wasp lays her egg or eggs. The larvae are mostly ectoparasitic on the abdomens of adult or nymphal plant hoppers, leaf hoppers, and tree hoppers. The position of the parasite on the host varies; more than one may be present; and many species exhibit polyembryony, with up to 60 individuals resulting from a single fertilized egg. The family is relatively uncommon.
