Adults are highly variable, the colouring resembling bird droppings. The forewings are pale ochreous with a narrow darker area at the base followed by a narrow oblique pale band, then a broad central band, a rather narrow curved pale band and finally several small irregular patches on the termen. The hindwings are pale ochreous with numerous wavy, pale brown lines on the dorsum. Adults are on wing from September to February.[4]
