The wings are marked with narrow brown fascia, three on the forewing, two on the hindwing. ab. arenosaria Haw. (= nogentina Th.-Mieg) is darker, more strongly dusted, the lines sometimes scarcely or not at all differentiated. ab. approximaria Haw. has the first two lines closely approximated, almost coalescent.ab. pellagraria Guen. is said to be larger, apex of forewing more produced, colour whiter, less irrorated, lines perhaps less waved, both wings with a black discal dot. Lyons. — ab. unicolorata Teich, almost unicolorous white, is said to be a prevalent form in Livonia. — The wingspan is 30–35 mm. The egg is oval, green, with fine reticulation. The larva is very variable, green or brown, usually with dark dorsal markings and sometimes with white dots.[1]

One or two broods are produced each year and adults can be seen at any time between May and August.[1] This species flies at night and is attracted to light.
