Lulworth skipper Lulworth skipper The Lulworth skipper ("Thymelicus acteon") is a butterfly of the family Hesperiidae. 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
Lulworth skipper the "Thymelicus" genus. Of Britain's five "golden" skippers—the others being the silver-spotted skipper ("Hesperia comma"), large skipper ("Ochlodes sylvanus"), small skipper ("Thymelicus sylvestris") and Essex skipper ("Thymelicus lineola")—the Lulworth is both the smallest and darkest. Beyond its small size, it is distinguished particularly by its dark, dun-coloured wings that appear with tinges of olive-brown; this darkening especially apparent in males. Variations are known to occur; in north-west Africa, the uppersides of the forewing and hindwing are darker, with hints of greenish or greyish brown. Similarly-coloured races occur in Spain, Elba, Crete, and other eastern Mediterranean islands. "T. acteon christi", endemic
