The wingspan is 7-8.5 mm. The base of the wing is white, this white colour sometimes spreading outwardly below the fold. The ground colour of the forewings is dark brown, reddish brown, or sometimes paler fuscous and then more or less irrorated. The hindwings are grey. Adults have been recorded on wing from April to September. Adults are on wing between June and July depending on the location.

The larvae feed on Betula species, including Betula nigra, Betula lutea and Betula occidentalis. They mine the leaves of their host plant. The mine has the form of a narrow and contorted linear mine. Older larvae live freely, skeletonizing the leaves, but leaving the upper epidermis intact.[2]
