Davey, P., 2009: A species of mire and moorland in northern and western Britain, the larval foodplant is unknown; abroad it is stated to feed on mosses (Musci spp.). In Dorset, old records from the north-east of the county, if valid, suggest colonisation of mire habitat in the past: Cranborne, three in 1902, 1903 and 1906 (Reverend F Fisher). More recently, six individuals were trapped in a variety of localities across Dorset in warm, humid westerly airflows. Medium-range dispersal is suspected from upland regions of south-west England or south Wales on these occasions: Walditch, on 24 July 2004 (M Parsons), West Bexington, on 27 July 1996 (R Eden), Lyons gate, on 29 July 2005 (T A Box), Portland, on 26 July 1997 (M Cade), Powerstock, on 24 July 2004 and Whitesheet, on 26 July 2004 (P Davey).
