Black Bess Beetle

Aulacocyclus edentulus


A 40cm long uniformly black ground beetle with fossorial front legs. Just above the mouth parts and in the mid-line was a small protruberance like a horn. Antennae were short, beaded and ended in at least three leaflets. Elytra were a shiny black (a deep purplish black) with fine ridges. The beetle had a distinct waist separating the thorax and abdomen.


Spotted near a grassy verge under bright lights.


The beetle was aware of me and my proximity to it. I could take a few shots before it reared up ( pic 2 & 3) and then I saw the elytra part a little before it took off ( pic #4) This beetles larvae feed on dead wood. Family Passalidae
