Davey, P., 2009: A local species in England and southern Scotland, the larval foodplant is unknown. In Dorset, the moth is confined to mainly dry heathland blocks within the Poole Basin where it is abundant very locally, and in these situations the foodplants may well fine-leaved grass species such as bristle bent (Agrostis curtisii) or wavy hair-grass (Deschampsia flexuosa).
The moth occasionally disperses over short to medium distances. The following light trap records refer: Chilfrome, on 20 August 2006 (S Philp), Badbury Rings, three on 4 September 2005 (P Davey), Shapwick on 20 August 2000 and on 22 August 2003 (P Davey). This example was trapped on a rather late date: Morden Bog, on 11 October 1996 (P Davey). Conservation agencies should include this species in habitat management plans for sites containing dry heathland.
