Common in broad-leaved woodland, fens, heathland, moorland and gardens throughout the British Isles, a species of conservation concern under the UK Biodiversity Action Plan. Widespread and common in Hampshire and on the Isle of Wight. Wingspan 34-38 mm. Usually unmistakable, although several not infrequent almost plain forms can be confusing, the wing-shape (costa straight and termen convex at apex) is diagnostic. Larva feeds within catkins of Black and White Poplar, and Sallow, over-wintering as an egg.
