The wingspan is 40–50 mm. The male has feather-shaped antennae, the female thread-shaped. The forewings have three narrow, wavy, dark cross-bands that are clear at the front edge, often blurry further back. The hindwings have two such cross bands, one of which is usually quite clear. The larva is naked, brown and gnarled and strongly resembles a dead oak twig.
The moths fly from May to August. The caterpillars feed on oak.
Similar species include Hypomecis punctinalis and Hypomecis sp.
