Swallowtail

Swallowtails are striking butterflies and strong fast flyers. The large yellow and black wings have a protruding tail, resembling that of a swallow. With a wingspan of around 10 centimetres, they are the largest resident butterfly in the UK. Britain has its own race of swallowtails (Papilio machaon britannicus) that's only found in the fens and marshes of the Norfolk Broads. The European race (Papilio machaon gorganus) is quite common and is found all over Europe, Asia and even North America. Swallowtails brood once, twice or even three times in a year.
