Its name is derived from Lulworth Cove in the county of Dorset, England, where the first specimens in Great Britain were collected in 1832 by English naturalist James Charles Dale. The species occurs locally across Central Europe, Asia Minor and North Africa, where its population is considered stable. Its numbers have declined in Northern Europe, leading to its European status of "vulnerable". Its range in Britain is restricted to the south coast of Dorset, however it is locally abundant and its numbers currently are perhaps at

Two outlying colonies also exist, at Burton Bradstock and on the Isle of Portland; the cause of the colony on Portland is unknown, but has been put down to either natural colonisation or released specimens. There is evidence to suggest that the Lulworth skipper is now more abundant in Dorset than at any other time since its discovery in 1832. Although colonies of Lulworth skippers existed in Devon, the species has, beyond single records, not be seen in the county since the 1930s. Similarly, records
