Local in birch woodland throughout Britain, with a scattered, discontinuous distribution. Erratically distributed in Hampshire and on the Isle of Wight, with notable populations around Fleet Pond, Botley Wood and Havant Thicket, but almost certainly under-recorded. Wingspan 9-12 mm. Day-flying. Adults difficult to distinguish from other Eriocrania species, and more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Birch, over-wintering as a pupa.
