Common in hedgerows, woodland and marshes, and on river-banks, throughout much of the British Isles. In Hampshire and on the Isle of Wight Mines and spinnings are common on sallows, willows and poplars in all three vice-counties. Wingspan 12-14 mm. Bivoltine, with a peak summer generation, the descendents of which overwinter. Imago seldom encountered at light, and more likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Sallow, Willow, Aspen, Black Poplar and Grey Poplar, subsequently living within a leaf-fold.
