Common in broad-leaved woodland, hedgerows, parks and gardens throughout the British Isles. Widespread and common in Hampshire and on the Isle of Wight. Wingspan 38-45 mm. Considered traditionally to be one of a species pair separated on flight period, no consistent genitalic or genetic differences have been found and certainly on the continent, 'Engrailed' is considered to be one species, which is followed here. Larva feeds on the foliage of many different woody plants, including Sessile and Pedunculate Oak, Downy and Silver Birch, Hazel, Hawthorn, Sallow, Broom, Buckthorn, Spindle, Wild Privet and Hornbeam, over-wintering as a pupa.
