- This page contains pictures and information about the Gasteruptiid Wasps
that we found in the Brisbane area, Queensland, Australia.
-
- Body length 25mm
-
- We sometimes see something long and thin, hovering near tree log moving
forward and backward very quick. It is so quick that we cannot recognize
what they are. They are the Gasteruptiid Wasp checking if there are the bee
or wasp nests that they can lay eggs on.
-
-
-
- The wasp was resting upside-down on a dry grass,
advertising its white tip.
-
-
-
- This wasp has the extraordinarily long ovipositor with white tip. We saw it once in
Karawatha Forest on May 2007.
-
-
-
- They are known to parasite on solitary bee and wasp
nests which may be in decaying logs, mud cells or in soil. Larvae consume the
host egg or larvae and then the pollen or prey stored.
-
-
-
- The wasps in this family are thin and long, They rest with fore wings fold
longitudinally. They are usually black or black with brown in colours, tip
of ovipositor is often white and as long as body.
