Yellow Antenna Black Wasp - ? Auplopus sp.

Family POMPILIDAE

This page contains pictures and information about Black Wasp with yellow antenna that we found in the Brisbane area, Queensland, Australia.


Body length 20mm



This wasp is common in Brisbane Eucalyptus forests. It is black in colour with yellow antenna. We usually see it flying and examining among tree trunks.



In late summer we saw this wasp on a dead tree trunk. It spent a lot of time checking each hole on the dead tree trunk. We believed those holes were made by the beetle larvae. The wasp was looking for those larvae, if found, will bring back to its nest for its young.



The wasp check every holes. For some holes, the wasp went inside and spent tens of seconds inside. We watched it for a few minutes, it had no luck and could not find any yet.





Here we would like to thank Professor Denis Brothers sending us email advised that this wasp is in the POMPILIDAE family.
