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. Tall, ungrazed grass is a favoured habitat due to oviposition and larval development; Lulworth skippers have benefited from the move away from tight grazing by sheep in the last century and recently outbreaks of myxomatosis among rabbit populations, which otherwise maintain a lower grass height. However, there
Lulworth Cove made a gap in the Portland and Purbeck limestone here, as well as a small arch. The sea has made its way through to the Wealdon clays and begun eroding them. The clay shows obvious signs of slumping, and is eroding very rapidly. Stair Hole shows one of the best examples of limestone folding in the world, caused by movements in the Earth's crust tectonics millions of years ago. Folding can also be seen at nearby Durdle Door and at Lulworth cove itself. Lulworth Cove Lulworth Cove is a cove near the village of West Lulworth, on the Jurassic Coast
