The forewings of this species are grey (ccasionally with an ochreous tinge) marked with pale fascia and radial lines which give it a mottled appearance. There is a pale sub-marginal line and a small discal spot. The hindwings are much paler and plainer also with a small black discal spot.[2] Melanism is quite common in this species. The wingspan is 17–21 mm.

The adults fly in May and June with a second brood sometimes emerging in August. The species flies at night and is attracted to light.

The larva feeds on the leaves and flowers of a wide range of plants (see list below). The species overwinters as a pupa.
