The ground colour is grey, irrorated or mixed with white, more strongly in the female. There is and angulated fascia at 1/3, slender and often indistinct dorsally. An irregular central fascia is sometimes interrupted near dorsum. The costal and terminal patches (seldom connected) are grey or fuscous, often blackish-marked, sometimes nearly obsolete. The hindwings are light fuscous or grey, in female darker, 6 and 7 short-stalked. The larva is pale greenish-grey ; spots small, black; head and plate of 2 yellowish-brown:[2] Julius von Kennel provides a full description.[3]
Adults have been recorded on wing in July. There is generally one generation per year, although two have been reported from Ireland.[4]
