Eucharitidae

Eucharitid wasps of the Afrotropical Region

(Life: Kingdom: Metazoa (animals); Phylum: Arthropoda; Class: Hexapoda; Order: Hymenoptera; Superfamily: Chalcidoidea)

Classification

Eucharitinae

Oraseminae

Distribution Worldwide, but most diverse in tropical and subtropical regions.
Biology Parasitoids of ant larvae. Eggs are laid into plant tissue. The mobile planidium larva attaches itself to an ant worker and is carried into the nest, where it transfers to a larva. The planidium then waits until the ant larva pupates and then commences feeding as an ectoparasitoid. The planidium will sometimes feed on an intermediate carrier such as a Thysanopteran if it initially is not successful in attaching to an ant worker when it hatches (Heraty, 2002).
