The wingspan is 4.6–6 mm. The head is black or sometimes a ferruginous-brown. Antennal eyecaps are white. The forewing ground colour is black and there is a somewhat bent shining silvery fascia hardly beyond middle ; outer half of cilia beyond a black line whitish. Hindwings are grey. Adults are on wing from June to July. There is one generation per year.
The larvae feed on Rubus arcticus, Rubus caesius, Rubus chamaemorus, Rubus fruticosus and Rubus saxatilis. They mine the leaves of their host plant. The mine consists of a highly contorted gallery, strongly widening towards the end. The frass in the second half of the gallery is dispersed. The larve mines venter upwards. There are several mines in a single leaf most of the time.
