Stigmella lapponica

(Wocke, 1862)

Wingspan 5-7 mm.

Fairly common throughout the British Isles, the adults of this single-generation species are on the wing in May, and the larvae can be found in June and July.

The foodplant is birch (Betula), and the mine is quite distinctive, being filled with cloudy greenish frass for the first part, then changing suddenly to a narrow central band of black frass.

The adults are coarsely-scaled and dull greyish-brown with an indistinct creamy fascia.
