Common in gardens, hedgerows and woodland throughout much of the British Isles, but not in northern Scotland. In Hampshire and on the Isle of Wight scattered records of individuals or small groups indicate a low population density. Wingspan 10-15 mm. Immediately recognised by the conspicuous white costal marking on the forewing [Bradley]. Larva feeds on Apple, Plum, Blackthorn, Cotoneaster, Pear, Rowan and similar, living within a spun or rolled leaf, over-wintering as an egg.
