Metallic Brown Spider Wasp


Brown Flower Wasp - ? Gymnothynnus sp.


This page contains pictures and information about Brown Flower Wasps that we found in the Brisbane area, Queensland, Australia.

Winged male 15mm, female 8mm 
We saw a wasp landed and rested on a dry grass with its abdomen tip attached with something. Looked a bit closer we found that the attachment was a wingless wasp. Then we understand it must be a flower wasps mating pairs. They flied away after we took a few photos.

To a female, wingless is an advantage when living on or under soil but it is also a problem to feed on flowers. Flower wasp evolved a mating behaviour which the male help the female on feeding. Their mating time is very long. It is common to see a male Flower Wasp carrying a wingless female, with tail to tail attached, flying between flowers. The transportation is part of the mating procedures. 
Photos were taken on August in Karawatha Forest.
