Davey, P., 2009: A declining species restricted to south-west Wales, Devon and Cornwall, Cheshire and a few counties in south-east England, the larva feeding nocturnally on wood-rush (Luzula spp.), cock's-foot (Dactylus glomerata) and wood meadow-grass (Poa nemoralis). In Dorset, the moth was discovered by Dr P Sterling on a large estate containing old, mixed woodland and parkland, situated at a relatively elevated position of one hundred and fifty metres above mean sea level. Most of the moths were trapped in the deer wardens garden with none of the preferred larval 'clumpy grass' microhabitat nearby. Until the habitat requirements of the Double-line at Melbury Park are better understood it is not possible to propose recommendations to protect and promote this fine species at the site: Evershott, (R Dyke), Melbury Park, two on 27 June 1996, two on 19 July 1996, 17 July 1999, six on 13 July 2002, five on 26 June 2003, fourteen on 26 June 2004 (Dr P Sterling et al).
The following light trap records are believed to have dispersed from moorland to the west of Dorset coincident with a breezy south-west to westerly airflow: Puddletown, on 2 July 2004 (H Wood Homer), Milton-on-Stour, on 1 July 2004 (J Burge).
