In south Hampshire and on the Isle of Wight, well-distributed and relatively common, but distinctly uncommon in north Hampshire, where mainly confined to the north-eastern heaths. Wingspan 4-4.6 mm. Adults difficult to distinguish from other Stigmella 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. The mines are described in the following link:
