The wingspan is 10.5–13 mm. The forewings are shining black with fawn coloured scales. The hindwings are light grey.[1] There is one generation per year.

The larvae feed on eastern larch. The larvae mine the leaves of their host. In fall, it constructs a shelter of needles and frass along a twig where it spends the winter. After the winter it resumes feeding while it lives in a tube that is composed of needles tied together with silk.
