Authority:([Denis & Schiffermüller], 1775)

Common in broad-leaved woodland, scrub, hedgerows and gardens throughout the British Isles. Widespread and common in Hampshire and on the Isle of Wight. Wingspan 22-28 mm. Differs from Fan-foot Zanclognatha tarsipennalis, and all other fan-foots, by having the median line being dead straight and the subterminal line curving towards the apex. In Fan-foot, this is the opposite - the median line is curved, whereas the subterminal line is straight. See the comparison image in the collection above for an comparative illustration of the two species together.
Larva feeds on the withered leaves of various deciduous trees and shrubs, including Pedunculate Oak, Downy Birch, Alder, Hazel, Hawthorn and Bird Cherry, over-wintering as a pupa.
