Notes: Local on moorland and in open woodland, in western England, Wales and Scotland. Unlikely to be recorded in Hampshire or on the Isle of Wight. Wingspan 28-30 mm. Waved Carpet Hydrelia sylvata is superficially similar, but Welsh Wave has a more clearly demarcated pale central band which is bordered by thin black fascia. Larva feeds on Rowan, Silver Birch and Downy Birch, over-wintering as a pupa.
