This is a very interesting and challenging moth. It has very distinct markings, the pale and dark being reverse of most options. The square, rather than curved, termen is distinctive. Despite an extensive/creative look at option (e.g. Plusiinae, Arrade sp., Neumichtis sp.) I can't find it either. Also from what I have found on line, it is not a C.S.I.R.O. introduction for control of W.O.N.S. - there seem to be no noctuids on that list.
