Wingspan c.13 mm.
A very distinctive species, distributed widely throughout much of Britain, although scarcer in the north.
The larvae feed on a range of Rosaceous trees and shrubs including hawthorn (Crataegus), rose (Rosa) and apple (Malus). They spin two leaves together and feed within, during May and June.
The flight period of the adult moths is July and August in a single generation. They are easily disturbed by day and at night can be attracted to light.
