Davey, P., 2009: A common species in Britain, the polyphagous larva feeding on the flowers of many plants including yarrow (Achillea millefolium), mugwort (Artemisia vulgaris), ragwort (Senecio spp.), goldenrod (Solidago virgaurea), wormwood (Artemisea absinthium) and goosefoot (Chenopodium spp.). In Dorset, the moth is widely distributed and at low density. It is commonest along the coast where yarrow and wormwood abounds, and rare on open heathland and in woodland. Elsewhere, the moth is frequent on unimproved grassland along the Purbeck Ridge and on the north Dorset downs where larvae have been found on ragwort. The national norm is a single brood in June and July. In Dorset a small number of May individuals have been noted at times of immigration, and these are likely to have originated from the Continent where a partial first generation is noted in some years, a few examples follow: West Bexington, 17 May 1997 (R Eden), Puddletown, 8 May 2000 (H Wood Homer), Wareham, 8 May 2008 (Mrs B Young), Gaunts Common, 19 May 1992 (P Davey).
