Common in woodland, scrub and hedgerows throughout much of the British Isles, except for the Northern Isles. In Hampshire and on the Isle of Wight abundant wherever hazel occurs. Wingspan 7-8.5 mm. Imago rarely comes to light, and more frequently recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Hazel, over-wintering as a pupa in a cocoon.
