Specimens of A. moretonella on the ALA show quite a large variation regarding the amount of white present from sparse black and white to very white examples. Bold Systems 4 shows 6 named species of the Ardiosteres genus, with I think two others: A. lacerata and A. tetrazona showing a similar pattern to A. moretonella. I would prefer a side-on view of the forewing pattern. however think this specimen is most likely A. mortonella
