Forewings pale grey or whitish-grey, sometimes brownish-mixed, sprinkled or strigulated with dark grey, sometimes more or less wholly suffused with blackish ; a blackish or dark fuscous streak along dorsum, forming triangular projections upwards before and beyond middle. Hindwings are grey.The larva is brown- blackish ; dorsal stripe broadly whitish.[2] It is a variable species, with some adults showing more blackish suffusion on the dorsal region.

Adults are on wing from July to August.[3] There is one generation per year.

The larvae feed on the leaves and flowers of Ulmus and Fagus species. They live in a slight silken web. Pupation takes place in a loose white cocoon on the trunk of the food plant or among plant debris on the ground.[4] Other recorded food plants include Quercus, Lonicera and Acer pseudosieboldianum.
