    The adult moths are pale brown with a pattern of dark speckles and spots, an indistinct pale-edged, possibly dotted, submarginal band on each wing, and a row of dark dots along the edge of each wing. The moths have a wingspan of about 3 cms. They typically rest on the ground with their wings flat, and the forewings covering the hindwings. The underside of each forewing has a black spot near the middle.
