A very variable species associated with sedges in wetlands. The forewings range from pale and almost unmarked to almost entirely dark or black.  There may be a small dark mark at the wing apex.  The sides of the face (genae) have a small black spot.

Good quality photos of  specimen - top and side views - showing wing venation and side of face.
