The wingspan is 11–13 mm. Adults are on wing in June.[2]

The larvae feed on Primula farinosa and Primula veris. They mine the leaves of their host plant. The mine has the form of a large, transparent, full depth blotch that starts in the basal part of the leaf. Most frass is deposited in the first part of the mine. The mine is strongly folded lengthwise. Full-grown larvae leave the mine to pupate. They attach the pupa to the apical part of a fresh leave.[3] Larvae can be found in May. They are dark red, mottled with greyish white.
