Swallowtails (Papilionidae)
The twelve European representatives of this family includes some large and colourful butterflies, of which the Swallowtails are the best known. Males and females tend to have similar wing markings, but can usually be distinguished by abdomen size and shape. Larvae mostly have bright warning colours, and are often conspicuous when feeding or resting.
Two species have been recorded in Britain:
  • Scarce Swallowtail: a very rare migrant
  • Swallowtail: restricted to the Norfolk Broads
