Common in orchards and woodland, and around old buildings, dry-stone walls and sea cliffs throughout the British Isles. Historically widespread and common in Hampshire and on the Isle of Wight, the 21st century has seen a significant decline in reporting rates: based on records received 2000-2023 this decline is in the region of 80-90%. The reason for this is unclear but may be at least in part due to competition with Tree Lichen Beauty which has increased dramatically in the same timeframe.Wingspan 23-31 mm. Dentate antemedian fascia extends from costa to dorsum, in contrast to superficially similar
Marbled Green C. muralis, in which antemedian fascia falls short of dorsum. Larva feeds on various lichens, often on walls and tree trunks.
