These pretty bugs, found in center of a dead paperbark or teatree trunk, scrap wood from side of road, dragged home and busted up for fire, but some of these bugs didn't survive their home invasion, I hope to have saved this family and relocated them to garden and sat under a pot, but the next morning all but this dead one has disappeared.
This was just sitting on a tree trunk. I think it is Chaetocnema wilsoni erichsoni
Old tree from Gonwandaland
