Not expecting to see moths at this time of year, especially out in the open like this one, I almost trod on it. Imitating a dead leaf it was so convinced of it's strategy it refused to flinch when I touched it. About 45mm across.
In an open area of short grasses within a dry eucalyptus woodland. Churchill National park.
These beetles were identified as Altica pagana by Ken Walker, but have been identified as Diachus auratus by Stephen Thorpe. I feel Diachus auratus is more likely correct as the beetles shone a bronze, golden colour - they were definitely not blue.
