Swallow Tail Butterfly at Strumpshaw Fen.

One of the most elegant and colourful of British Butterflies only to be found in the Fens of Eastern England. 

They feed on wild carrots, Milk Parsly and Fennel

The British subspecies is called ssp.britannicus  to set it apart from its European cousins which are increasingly being found along the south coast thought to be due to global warming - they are powerful fliers and able to cover long distances.

What a beauty ....... enjoy.
