Common throughout much of Britain and western Ireland. In Hampshire and on the Isle of Wight well-distributed and common. Wingspan 3.5-4.8 mm. The species appears to be partly or wholly parthenogenetic. 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 Hazel and Hornbeam, over-wintering as a pupa. The mines are described in the following link:
