Local on heathland, downland, open woodland, scrubland and in gardens throughout much of southern England, spreading into northern England, a species of conservation concern under the UK Biodiversity Action Plan. In Hampshire and on the Isle of Wight frequent amongst Clematis on the chalk, and occasional elsewhere, where it possibly uses cultivated Clematis as its larval foodplant. Wingspan 33-40 mm. Distinguished from all other medium-sized emeralds by the rounded wings and curved cross-lines. Larva feeds on Traveller's-joy and cultivated Clematis.
