It is a small moth with pointed forewings crossed by two dark bands over a ground colour that ranges from light to dark reddish brown, and pale grey hindwings marked with a small dark spot.

Caterpillars feed on the flowers of shrubs such as gorse and holly rather than on leaves, and the species usually produces two generations a year, with adults sometimes appearing as early as January in a mild winter.
