General Species Information:
Found on Ellura (in the Murray Mallee, SA) and elsewhere
~12 to ~13.5mm
Most of these Carcass Beetles (Omorgus sp) play dead for long periods of time. We've only managed to photograph one that actually got up and started walking around.
This one does seem to have the Arrow-warts of Omorgus euclensis, but the tibial teeth are more rounded and this one is smaller than the other we've measured.
We thought it possible a gender difference between Omorgus euclensis, but Paul said "generally external variation in tubercles is not an indication of gender", so we've assumed a different species.
