Wingspan 4-5 mm.
Occurring in southern and north-west England, the foodplant of this species is birch (Betula). The larvae create a distinctive mine which starts off with a brownish blotch and then becomes a gallery completely filled with greenish-brown frass.
The adult moth has dark wings with a silvery fascia, orange head and white eyecaps.
The mines can be found in June and July, and occasionally in September. The adults are on the wing in May and August.
