Lulworth skipper
The Lulworth skipper (''Thymelicus acteon'') is a butterfly of the Hesperiidae family. 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".〔(【引用サイトリンク】 url = http://butterfly-conservation.org/679-872/lulworth-skipper.html )〕 Its range in Britain is restricted to the south coast of Dorset, however it is locally abundant and its numbers currently are perhaps at their greatest since its discovery there.〔
With a wingspan of 24 to 28 millimetres, females being larger than males, the Lulworth skipper is a small butterfly, the smallest member of the ''Thymelicus'' genus in Europe and among the smallest butterflies in Britain. Aside from the size difference, the sexes are distinguished by females having a distinct circle of golden marks on each forewing. Due to their likeness to the rays around the eye of a peacock's feather, these are often known as "sun-ray" markings, and they can faintly appear on males.
== Taxonomy ==
The Lulworth skipper was first described by German entomologist S. A. von Rottemburg in 1775.〔 The butterfly was first discovered in Britain on 15 August 1832, when specimens were taken from Lulworth Cove in Dorset by English naturalist James Charles Dale It was introduced the following year as the Lulworth skipper (''Thymelicus acteon''), a name that has remained unchanged; it is the only one of Britain's vernacular butterfly names for which there has never been a proposed substitute.〔
