Lulworth skipper 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 genus "Thymelicus" 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. The Lulworth skipper was first described by German entomologist
Day Skipper during the practical course. Some sailing Schools holding RYA recognition may allow Day Skipper training without first taking the shore-based course, if the student can navigate up to Day Skipper standards. However, theory knowledge will still be tested while out on the water. RYA Recognised sailing Schools are displayed on the RYA website. The theory part of the Day Skipper qualification is either a shorebased (classroom) course that normally takes 36 hours, including an exam. Alternatively, this can be completed online by distance learning which offers greater flexibility in study. Course Content includes: The practical element of the day skipper
