Nationally scarce (Na) in damp heathland and mosses in parts of southern England and in north-western England, where now very rare. Fairly common in boggy areas of the New Forest, and eastwards to Emer Bog although not in recent years; formerly on heathy ground in Botley Wood, but not since 1960. No recent record from the Isle of Wight, and the old record for northern Hampshire remains unconfirmed. Wingspan 24-27 mm. Similar to Little Emerald Jodis lactearia
, but cross-lines straighter. Larva feeds on Heather, Cross-leaved Heath, Creeping Willow, Gorse and other woody plants, over-wintering as a pupa.
