Nationally scarce (Nb) in woodland, scrubby heathland and on sea cliffs in southern England and Wales. Has decreased in numbers considerably since coppicing went out of favour, but does appear to be expanding its range in Sussex. In Hampshire appears sporadically at sites such as Oxenbourne Down and Swanwick HWT, but does not seem to survive in any one site for more than a few years. Not recorded from the Isle of Wight to date. Wingspan 27-30 mm. Welsh Wave Venusia cambrica
is superficially similar, but Welsh Wave has a more clearly demarcated pale central band which is bordered by thin black fascia. Larva feeds on Sweet Chestnut, Alder, Downy Birch, Silver Birch and Sallow, over-wintering as a pupa.
