Davey, P., 2009: A coastal sandhill and heathland species in Britain, the larva feeding on various small herbaceous plants. In Dorset, the moth is locally common on coastal sandhills and on heathland, but is absent from clay and chalky soils. The White-line Dart is a highly variable species, and occasionally small dark forms approaching the closely related continental species Euxoa crypta are observed.
