Davey, P., 2009: A local species in Britain, the larva feeding on heather (Calluna spp.) and heath (Erica spp.). In Dorset, the moth is local and declining, and exclusively confined to heathland on sandy soil. The Grey Scalloped Bar occupies the same habitat as the Bordered Grey1938, although the damper regions where heath grows, provide additional potential habitat for this species. The moth may occasionally be flushed from its resting-place during the day and has been found at rest on sand at Canford Bottom (per W Parkinson Curtis ms). The scarcity of this species contrasts markedly with the historical comments: "at times quite common in the heath area", "abundant at Poole" and "abundant at Studland" (per W Parkinson Curtis ms). It seems that both species are casualties of the fragmentation and reduction of heathland in the intervening years. The few recent records indicate that it is still present across the Poole Basin, in such places as Decoy Heath, Stoborough Heath, Arne, Holt Heath, Sopley Common and Matchams, although numbers are always low. Occasional wanderers appear well away from core habitat, and the following light trap records suggest short-range dispersal: Milton Abbey, on 26 May 1967 (H Edmunds), Scar Bank, on 5 June 1933 (A Russell), Shapwick, on 2 June 2000 (P Davey), Wimborne, on 21 June 1983 (Miss M Brooks).
