Gasteruptiidae

Overview

Females oviposit in the nests of solitary bees (Apidae) and wasps (Vespidae) , where the larvae are predator-inquilines, eating the host egg or larvae and consuming the pollen store. Adult gasteruptiids may be seen on flowers or hovering near bare ground, logs or trees.

Description

Gasteruptiidae are one on the most easily recognised families of parasitic wasps. They are particularly distinctive because of their slender subclavate metasoma, the dorsal articulation of the metasoma to the propodeum, the elongate neck-like propleura, and expanded hind tibia.

Distribution

More than 180 species of gasteruptiid wasps occur in Australia: 115 species in the subfamily Gasteruptiinae ( Gasteruption spp.) and more than 70 species in the subfamily Hyptiogastrinae (two genera). Gasteruption is worldwide in its distribution, although Australia has about 25% of the world's fauna. The Hyptiogastrinae are largely confined to Australia, although there are two species from New Zealand, several species from Fiji, New Caledonia, New Guinea and Vanuatu and two species in South America.

Further information about the Gasteruptiidae can be found in Jennings & Austin 2002, Jennings & Austin 2004 and Mason 1993.
