Davey, P., 2009: A very local species with a restricted distribution in the British Isles, the larva initially blotch-mining the leaves of common rock-rose (Helianthemum nummularium) and later feeding on the underside layer of the leaf, leaving the top intact. The males fly actively in sunshine, but females tend to remain at rest on downland plants. In Dorset, the moth is local, being restricted to unimproved grassland on chalk downland where its foodplant abounds. In the best sites it can be common and in such places may be observed visiting flowers such as knapweed (Centaurea spp.) and field scabious (Knautia arvensis), but such sites are few and far between. Conservation measures should include sympathetic grazing of chalk downland to promote herb-rich communities containing common rock-rose, a plant most often associated with short turf and medium sward unimproved grassland habitats.
