The moths reach a wingspan of 34 to 38 millimeters. The upper side of the forewing is colored gray-brown. The silver-white shimmering, teardrop-shaped blemish, which resembles the gamma (ɣ) from the Greek alphabet, is relatively large and sometimes filled between the two branches of the sign. The middle field between the cell and the inner edge is colored black-brown and bordered by narrow whitish transverse lines. The post-distal region is also black-brown and is sharply delimited by the strongly jagged wavy line. The upper side of the hind wing is gray-brown in color and slightly darkened at the edge. Thorax and abdomen are furry hairy and provided with tufts of hair, the proboscis is well developed.
