Local in hedgerows and woodland margins throughout much of southern England, with records north to Yorkshire. In Hampshire virtually restricted to the south-east, where it remains reasonably numerous around the three harbours, but very rarely recorded in north of the county and on the Isle of Wight; perhaps overlooked. Wingspan 8-9 mm. Larva mines leaves of English Elm and Small-leaved Elm, over-wintering as a pupa.
