The wingspan is 25-37 mm. Adults are pale vinous lavender grey, with two narrow brown-bordered, yellow, obliquely transverse bands on both wings. The outer band crosses from the apex to the middle of the abdominal margin and the inner band from the middle of the costa to one-third the latter. The costal edge and apex of the forewings are ochreous yellow. There is a slight curved brown streak on the forewings and a small spot on the hindwings at the end of the cell.
