Davey, P., 2009: A rare species with only a handful of voucher specimens from Kent, Dorset and Cornwall, the larva feeding on the flowers and seeds of sheep’s-bit (Jasione montana). A single example was found on sheep’s-bit rich sandy heaths at Studland about forty years ago, and has been discovered very recently on Hengistbury Head. Sheep’s-bit is a local plant of sunny banks, heathland edges and dunes, confined mainly to the Poole Basin: Studland, at MV in 1961 (J Bradley), Hengistbury Head, four at MV light on 30 June 2001 (M Jeffes, conf. Dr P Sterling), several larvae in seeds of sheep’s-bit on 20 July 2001 (Dr P Sterling), and subsequently (M Jeffes). Recommendations for the Studland and Hengistbury Head reserves would be to protect and promote the host plants where they occur in sandy heath microhabitat and monitor moth populations to gauge the health of colonies.
