Lulworth skipper of occurrences exist for Cornwall, but they have not been verified as native colonies. Habitats are primarily on unfertilised calcareous grassland; this includes chalk download, coastal grassland and undercliffs in Britain. In all of these habits Tor-grass ("Illustration 2"), the butterfly's sole food plant and that on which it lays eggs, is widespread.
