Gallery - Swallowtails
A large group with over 500 mostly large and colourful butterflies, mainly tropical. Most have tailed hind wings and all have 3 pairs of functional legs. The caterpillar has a retractable fleshy process behind the head. The pupa is usually attached to the food plant in a upright position by tail hooks and a girdle of silk.
This butterfly is common throughout most of Europe but in the British Isles it is restricted to the Fens of East Anglia.
