Davey, P., 2009: A sparsely distributed species in England, the larva feeding on the roots and inner stems of butterbur (Petasites hybridus). In Dorset, the moth is local and under-researched. The foodplant is virtually absent from Purbeck and sandy soils, but forms colonies along streams and sometimes on damp verges in the west and north of the county. It is likely that the moth will be found in any site that supports reasonable quantities of butterbur. Actinic light trapping among their foodplant at the end of July and early August may prove successful. All county records follow: Iwerne Minster, on 26 August 1959, 15 August 1966 (H Moore), Tarrant Monkton, on 20 August and 24 August 1951, six on 19 August and two on 21 August 1953 (Dr H King), Wimborne, around butterbur plant on 17 August 1951 (Dr H King), Cranborne watercress beds, on 24 August 1955 (Dr H King, A Redgrave), Puddletown, on 4 August 1999, 13 July, 16 July, 20 July and 2 August 2002 (H Wood Homer), Bere Regis, four between 1 August and 9 August 1995, 17 August 1996 (S Barrett), Monkton Up Wimborne, on 17 August 1984 (Miss M Brooks). The following example, trapped on Purbeck where the foodplant is absent, is a suspected dispersed moth or immigrant; winds were between east and north-east at the time of capture: Scar Bank, on 17 August 1947 (A Russell).

This species may be confused with the female Rosy Rustic²³⁶¹. Diagnostics include: grey-brown ground colour, not red-brown ground colour; more broad-winged, less rectangular.
