The wingspan is 6–7 millimetres (0.24–0.28 in). Adults are on wing in January and again in June.[2]
The larvae feed on Carex montana. They mine the leaves of their host plant. The mine has the form of a white elongate gallery in the top region of the leaf. The frass is deposited irregularly. Pupation takes place outside of the mine.[3] They are dirty yellow with a pair of grey dorsal length lines and a yellowish head. Larvae can be found from April to the end of May.
