Lulworth skipper  (Thymelicus acteon)

The Lulworth skipper is single-brooded; adults fly between late June and late September, and eggs are laid in small groups in flower sheaths of tall patches of tor-grass. After hatching three weeks later, the larvae spin a cocoon in which to hibernate. They emerge the following spring and create tubes in which to live by spinning the leaf together. Pupation occurs amongst the clumps of tor-grass (2).
