In Hampshire an essentially garden or suburban species, colonies often affecting a single apple tree, and has been attracted to pheromone lure in several localities. Not recorded from the Isle of Wight to date. Wingspan 15-22 mm. Day-flying. The early stages may be sought during the winter months, but the use of synthetic pheromone lures used to attract males has led to a marked increase in records of the species in recent years.
