The moths reach a wingspan of about 28 to 37 millimeters. The basic color of the fore wings is dark brown. The middle field is bordered on both sides by gray-white or brown-white transverse bands and shows a strong jagged bulge outwards. On the white wavy line, several black arrow spots stand out in high contrast. Below the apex is a large, dark, crescent-shaped spot on the upper outer edge.
