Davey, P., 2009: Local in England, the larva feeding on bird's-foot trefoil (Lotus corniculatus), and trefoils and clovers (Trifolium spp.). In Dorset, this xerothermic species is associated with unimproved herb-rich grassland on well-drained chalky soil downland, particularly where there is rocky or bare earth terrain. It ranges from frequent inland to common along the Jurassic coast. Recommendations for promoting this species on chalk downland SSSI's include setting grazing levels that create short turf regions within the grassland mosaic and to physically create scraped chalk surfaces to provide high-temperature microhabitat for the adults to bask by day.
