Swallowtail Caterpillar feeding on Milk Parsley

A Swallowtail Butterfly Caterpillar (Papilio machaon Britannicus) feeds on the seed heads of Milk Parsley. The caterpillar is totally reliant on this food plant so I wanted to show the importance of this relationship and the Fenland habitat where Milk Parsley thrives. As all the flowers had been shed I was able to show the spoke like structure of the plant which forms a pleasing design.
