Crystal skipper Crystal skipper Atrytonopsis quinteri, the crystal skipper is a newly described butterfly (family Hesperiidae) that is found only along a 30-mile (50 km) stretch of barrier islands in North Carolina. The skipper was first discovered in 1978 and the paper describing it as a full species was published in 2015. The crystal skipper is endemic to Bogue Banks and Bear Island in North Carolina, USA. Bogue Banks is approximately 25 miles long and Bear Island is about 3.5 miles long. The skipper is also found on several human-made dredge spoil islands within the vicinity of these two natural barrier islands.
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,
