Davey, P., 2009: A widespread species in Britain, the larva feeding on sallow and willow (Salix spp.), and poplar (Populus spp.). In Dorset, the moth is locally common on wet heaths, in damp woodland and on damp grassland where sallow is dominant. It is frequent in river valleys where willow or poplar trees are plentiful. It is virtually absent from open tree-less situations.
