The larva is active from late summer until April (Forbes 1923; Koster & Sinev 2003).IdentificationThe forewing is dark brown and eight to ten millimetres in length. Two dark brown scale tufts with silver tipped scales are visible on the inner margin in the median and postmedian area, with the latter often more distinctive. Paler markings vary from straw to light brown and is usually present along the inner margin, but often elsewhere as well. The hindwing is light brown and the remainder of the body is dull brown as well.
