Lulworth skipper Netherlands where it is now extinct. This decline has led to the butterfly's European status of "vulnerable". Isolated populations of the species in Armenia are also threatened, although not yet included in the National Red List. It is also listed as threatened under the United Kingdom Biodiversity Action Plan. In Great Britain, where the butterfly reaches the northern limit of its range, its distribution is restricted to the southern coastline of the county of Dorset. Here, both the population and range have changed little in recent decades; it is locally abundant, with the majority of colonies found on the coast
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
