ID pointers: One of several in the group that can be difficult to identify. A longish forewing whitish-grey ground colour with various cross-band markings of darker brown. A small “X” shaped mark at about two thirds in the cross-band. Usually has areas of ochre background colour which helps to distinguish from other similar species. The white sub-terminal and the terminal cross-lines curve towards each other to form an X , but this character is often shown by other species.
