Common on woodland edges, hedgerows, scrubland and gardens throughout the British Isles. Widespread and common in both Hampshire and on the Isle of Wight. Wingspan 12-16 mm. Female could be confused with I. oehlmanniella but yellow marking on costa (if present) is closer to head than adjacent tornal spot, also has relatively narrow scales on the hindwing (MBGBI Vol 1). Larva mines leaves of Hawthorn, living within a movable case, subsequently feeding in the fallen leaves.
