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 skipper is evidence to suggest that minimal grazing is not detrimental to the species, and may in fact be beneficial in that it encourages the growth of flowers that act as adult nectar sources.
