The adult moths of this species have grey forewings with variable black zigzag lines and spots, including a 'V' shaped mark in the cell. It seems that this mark may degenerate into three dark spots. The hindwings are pale yellow, each with a grey comma near the middle, and a large grey area at the wingtip. The wingspan is about 2 cms.
