I have photos of three moths that are all pretty similar and am posting them as three different moths when they in fact may all be the same (e.g. male vs female).
This uncommonly observed moth matches (Mamastra) dictyota, a moth species whose status taxonomically is uncertain. Moths of Victoria (Part 9) classifies it in a group 'No Available Genus' (NAG) 1 in the subfamily Hadeninae. The ALA lists and illustrates it amongst the moths in a Species Inquienda, This is a new species recorded for CNM if confirmed.
