I also find the melanistic specimens very striking but my favourite is the first single specimen after the complete drawer, you would almost believe it was another species, it is so different from the normal specimens.

Here are two historic Papilio machaon britannicus specimens from Whittlesea mere in Huntingdonshire. They were captured in 1820 and are in the J.C. Dale and C.W Dale collection at the OUNHM. Probably two of the oldest British Swallowtails specimens in existence . Whittlesea Mere together with the adjacent Holme and Yaxley fens were part of an area known as the Great Fen. The Great fen including Whittlesea was completely drained by 1850 with the loss of not only the Swallowtail but Lycaena dispar dispar. Lucky were those that visited this area before the drainage schemes converted the area into vast cornfields.   |

A little question.
Why theire is a ssp britanicus?
As far as i know these butterfly can fly long distances.
So the butterfly's could simply fly from france to great brittain.
This means the local butterflys arent a local population.
So why this ssp?
Greets jens
p.s. that are very nice abberations

Greets jens p.s. that are very nice abberations Hi jens, I am pleased you liked the Swallowtail aberrations The British population is quite different from the population found on the continent. It is more heavily marked and is only found in Fenland in East Anglia [ now unfortunately only in the Norfolk Broads] and has been isolated for a long time. Subspecies gorganus from the continent occasionally is a migrant to our shores. P. machaon gorganus has bred here on the south coast but has never established itself here in Britain. |

Apparently P. machaon gorganus as a migrant is being spotted along the south coast of Hants and Dorset in the U.K and has been breeding. It would be nice if it was here to stay. Two subspecies on the Island would be great.

Migrant gorganus are NOT a good news for britannicus, as they can interbreed and dilute britannicus patterns...

Migrant gorganus are NOT a good news for britannicus, as they can interbreed and dilute britannicus patterns... It's happened a few times before. The most well-known was when gorganus established itself on the Sussex coast for a few years in the 1940s. Such colonies never seem to survive for very long so it's very unlikely that they'd reach Norfolk where britannicus flies. Bob |

Bob,
Unfortunately with global warming, I am afraid gorganus will more and more be adapted to Britain...

I see little danger from the continental gorganus to britannicus. Papilio machaon gorganus has bred here before but has not established itself. Even if gorganus did become a resident which I think is unlikely it would probably be along the south coast. britannicus breeds in a highly specialized habitat of wet fenland surrounding open water. It has been suggested the main threat to britannicus would be if sea levels rise and the flat area of the East Anglian fens with its freshwater broads were inundated with salt water. Hopefully this nightmare scenario will never happen. Peter
