|[Note Guidelines] Photographer's Note|
|First listed as a British species in 1667, this large butterfly became extinct in the British Isles around 1925 with its last remaining stronghold in the south-east of England. This species was always considered a rarity in the British Isles by early entomologists, although it is often very common on the continent.|
This species forms discrete colonies that fluctuate greatly in numbers, although the cause of the ultimate demise of this species in the British Isles is a mystery since its foodplants can be found in abundance in all of its former sites. Disease (fostered by poor autumn weather), relatively-mild winters and increased predation by birds have all been suggested as potential causes of this demise. There was a successful reintroduction in Fife, Scotland, although this was only able to survive with appropriate protection of the larvae from birds.
