Figs. 3,3a,3b Larvae in various stages of growth

The wingspan is 14–18 mm. The ground colour of the wings is white (silky in appearance). There are fine brown cross-lines across both forewings and hindwings and a row of black dots along the margin of both wings. Asthena amurensis Stgr., from the Eastern Palearctic , is smaller, with distinct discal dots but wanting those of the distal margin.[2] The larva is slender, pale with large red spots, with quite long, dark setae.

There are two generations per year with adults on wing from mid-April to August.

The larvae feed on Corylus avellana, Betula and sometimes Carpinus betulus. Larvae can be found from May to September. It overwinters as a pupa.
