Wasp-like Longicorn Beetle - Hesthesis variegata or Hesthesis bizonata


This page contains information and pictures about Wasp-like Longicorn Beetles that we found in the Brisbane area, Queensland, Australia.

Body length 20mm
This Longicorn Beetle mimics a wasp (Eumeninae ) to gain protection. Besides its colours and body shape, the beetle moves like a wasp too.

To mimic a wasp, the beetle evolutes the very short elytra (wing cover). There are the orange-yellow bands on its abdomen. On its 1st and 2nd abdomen segment there are the yellow edges to make it has the narrow-waisted look.

When we came close to the beetle, the beetle put up different wasp-like postures and movement. After a few try and failed to scare us, the beetle flied away.

On Dec 2005 we found the an insect resting on a She-oak tree Casuarinaceae. We though it may be a Wasp-like Longicorn Beetle but still afraid that it could be a real wasp. We came close very carefully then confirmed it was a wasp-mimicking beetle. We took only one photo before it flied away.

Once learnt how to recognize this beetle, we found they are quite common in Brisbane. This set of photos were taken in Karawatha Forest Oct 2006.
The beetle can be found feeding on flowers. Larvae related with Eucalyptus and Leptospermum
