Davey, P., 2009: A local species in the British Isles, the larva initially mining the leaves of common sorrel (Rumex acetosa) and then feeding on the outer surface of the plant's lower leaves. In Dorset, the moth is local, frequenting unimproved grassland on calcareous and neutral soils. On optimum sites it can be abundant and in such places may be observed visiting flowers such as knapweed (Centaurea spp.) and field scabious (Knautia arvensis).
