A moth with a wing span of about 30 mm. It was more grey than brown with the fore wings showing a central transverse band. Each fore wing had two oblique black lines, one running from wing base downwards to the inner margin and a shorter one from the apex of each fore wing running upwards.
Spotted under bright lights on a warm night in a suburban garden. Mixed native trees around. Also near a national park.
I am hoping the moth will return tonight so I can get a better shot/natural light. Thanks to Cathy Powers for confirming this as Dysbatus.
