The wingspan is 9–13 mm. The head is white. The thorax is white, sometimes anteriorly fuscous-sprinkled. Forewings are white, irregularly irrorated with fuscous; some longitudinal series of blackish dots; antemedian dark fuscous fascia reduced to two spots, discal and dorsal; two white spots on costa posteriorly, separated by a dark fuscous spot; cilia coppery-tinged, with two dark purplish-fuscons lines. Hindwings are pale fuscous. The larva is reddish-brown; dorsal line broad, paler, becoming indistinct posteriorly; spiracular broad, yellowish-white; head pale yellow-ochreous.[4]

They are on wing from May to June and again in August in two generations per year.[5]

The larvae feed on Betula species. They feed on the parenchyma on the upperside of a leaf, beneath a silken web.
