Range & Status
Widespread in Britain with a coastal bias, north to Norfolk, Worcestershire and south Wales, but declining as a result of loss of dry grassland.
Recorded in Cornwall since 1905; since 1980 in VC1 at Bessey' s Cove (1987), Cubert and the east side of The Lizard (both 1983); in VC2 at Nare Head, Northcott Mouth (Bude), Pendower Beach, Veryan Bay (all 1989) and Trebarwith Strand (1995). Since 1993, recorded annually at several coastal sites in southeast Cornwall, notably in the Rame Head area, as well as further records from Perranporth (2002), Sandy Mouth, Bude (2006) and St. Agnes Head (2007).
Habitat & Ecology
Occurs in dry, open grassland. Adults occur from May to September, nectaring and basking. The larval habits are unknown, possibly feeding on subterranean root aphids.
Continuing loss of open grassland.
Several post-1980 sites are on National Trust land managed for invertebrate conservation.
