Local in woodland, gardens, orchards and parks throughout much of southern Britain. In Hampshire locally common amongst large poplars, mostly in the south-east, with only occasional scattered records elsewhere, and none on the Isle of Wight in recent years. Wingspan 13-15 mm. Distinguished from G. dealbana by the stronger and more extensive ochreous suffusion of the ground colour, the less angulated, straighter-edged basal patch and the black-centred ochreous apical spot of the forewing [Bradley]. Larva mines leaves and petioles of Poplar, living between leaves and petioles spun together with silk, subsequently burrowing into and feeding on stems.
