Lulworth Skipper: our very own butterfly

Lulworth Skipper: our very own butterfly

The Lulworth skipper (Thymelicus acteon) is named after the place where it was found, Lulworth in the Isle of Purbeck, and is a butterfly exclusive to Dorset. It occurs all along the Dorset coast but most noticeably along the cliffs from Ballard Down to White Nothe Point. It once occurred on most of the Purbeck Ridge too, from Ballard Down to Lulworth but sadly it now seems to have disappeared totally from this area. Whilst is becoming scarcer, where it occurs it can be an abundant species. 

The other thing with Lulworth skipper seems to be that it is emerging as an adult sooner than it used to. It used to be around only for a couple of weeks in early August but now reports in mid June are not uncommon. Their time on the wing has extended and they can be still seen in August.

The main feature of this little member of the skipper family are the rays of golden sunshine on the wings! It is about the same size as its two close relatives, the small skipper and the Essex skipper and so those golden rays are important as a diagnostic feature. Whilst the adult insect loves to feed on knapweed (as in this photo) it can also be frequently seen on other members of the thistle family as well as restharrow and wild marjoram. The larvae feed on many species of grass, especially tor-grass, which is why rough downland suits it as its preferred environment.
