Davey, P., 2009: A species mainly confined to damp, deciduous woodland in the southern-most counties of England, the larval foodplant is unknown. In Dorset, the moth as a potential resident has been recorded and evidenced once in recent years from old, neglected woodland on ill-drained clay soil with holly understory, bilberry and deep leaf litter. Although the precise status of the moth in the county is unclear, especially as its host foodplant is unknown, research is recommended to locate viable colonies of the moth in the following locality and gather information on its habitat requirements: Holt Forest, two at MV light on 21 July 1997 (P Davey).

The following examples were trapped on the coast, and immigration is suspected on both occasions from northern Europe: Scar Bank, at light on 1 October 1933 (A Russell), Durlston, at MV light on 8 August 2003 (S Nash).
