Davey, P., 2009: A local species found mainly in south-east England, and absent from northern England and Scotland, the larva feeding on purple moor-grass (Molinia caerulea) and false brome (Brachypodium sylvaticum). In Dorset, the moth is locally abundant in wet heaths, conifer plantations and bog habitat in the Poole Basin where purple moor-grass is dominant. Elsewhere, the moth occurs at low density in wooded localities, and in these situations false brome is one of the host foodplants. Singletons occasionally turn up at light traps elsewhere and these are likely to be dispersed examples from woodland or heathland. The following light trap records are likely to be partial second generation moths: Puddletown, on 13 September 2003 (H Wood Homer), Shaggs, on 11 October 2007 (L Hill), Chase Wood, on 2 September 1997 (P Davey), Arne Wood, on 29 September 1984 (B Pickess).
