The wingspan is 11–12 mm. The forewings are nearly immaculate, very pale shining ochreous. The hindwings are whitish ochreous.[2] Adults are on wing from the end of June to mid-July.
The larvae feed on Larix species (including Larix decidua, Larix kaempferi, Larix laricina and Larix occidentalis) and Picea glauca.[3] Young larvae bore through the terminal twigs of their host plant, effectually killing the twigs and stopping further growth. In fall, they cut a circular exit hole at the base where pupation takes place.
