Remarks: This wasp is approximately 3 millimetres long and emerged from a gall on Bossiaea eriocarpa. Female wasps lay their eggs in the tissue of the plant. In response, the plant forms a gall around the foreign body – the egg. The young wasp feeds on the plant tissue inside the gall. It pupates in the gall and emerges as a fully formed adult wasp.
The galls were photographed in September and the wasps emerged in October.
Associations: Bossiaea eriocarpa.
