Davey, P., 2009: A coastal species in southern England and Wales, the larva feeding on a herbaceous plant species. In Dorset, the moth is confined to sea-cliff habitat with no geological preference, where it is common very locally. The national norm is for a single brood in July and August, but the following light trap records suggest a partial second generation in some years during the autumn: West Bexington, on 24 September and on 16 October 2005 (R Eden), Portland, on 25 September 1961 (C de Worms) and on 17 October 1996 (M Cade), Durlston, on 12 November 1990, 12 November 1995, two on 16 November 1997 (P Davey), and on 19 October 2008 (Dr J Clarke).
Crescent Darts noted inland are few and are likely to refer to dispersed individuals from core coastal habitat. The following light trap records refer: Iwerne Minster, on 10 July 1955 (H Moore), Colehill, on 27 June 1964 (H Driver), Bere Regis, on 5 July 1996 (S Barrett).
