Geometridae » Ennominae
Variable species, which closely resembles the Small Engrailed (E. crepuscularia). Some authorities consider them to be conspecific. The ground colour of the wings is buff or grey variably marked with darker fascia and a pale postdiscal crossline. The darker markings are not usually as strong as in the rather similar Willow Beauty. Melanic forms occur fairly frequently.
There are two generations, flying in March and April, and then in July and August, but in the northern parts of its range it is single-brooded, flying in April and May. 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.
Frequenting woodland, gardens and other bushy habitats,
