It has a scattered distribution in central and southern Europe, and several isolated populations in north-eastern Turkey and in Armenia. This species has a wingspan of 26–28 mm and, typically of its genus, can be very difficult to identify in the field. It is sometimes considered a subspecies of the carline skipper ("P. carlinae") as the two are known to interbreed where their ranges overlap in the Alps but can usually be recognised by the prominent squarish, rather than c-shaped, white spot near the costa
Lulworth Cove cove is where the weak clays and greensands have been eroded. At the back of the cove, the sea has been unable to erode the chalk as fast because chalk does not dissolve in the sea acids. The unique shape of the cove is a result of wave diffraction. The narrow entrance to the cove causes waves to bend into an arced shape, as is visible in the photograph below. Lulworth acts as a staircase to this part of the Jurassic Coast. As well as the cove, across Hambury Tout (the large chalk hill to the west) is Durdle Door,
