Readily distinguished from the others by the mostly yellowish stigma and wings veins and a yellowish tinge to the membrane in the basal part of the wing. The tibiae are pale yellowish and the basal tarsal segments yellowish-brown.

The caterpillar-like larvae are pale green with a buff head and a pair of whitish stripes down the back. They feed on the foliage of willows, birch and hawthorn. Adults fly from May to July.
