Butterfly Conservation poll is open until 7 June with choice of 60 species from small tortoiseshells to purple emperors

Will it be the rapidly disappearing former garden favourite, the small tortoiseshell? Or the poet John Masefield's oakwood haunting thing", the charismatic purple emperor? Or perhaps the brimstone, the ultimate harbinger of spring?

The question of which is Britain's favourite butterfly is being put to a popular vote for the first time. The charity Butterfly Conservation is running the poll, which runs until 7 June, giving people the chance to choose their favourite from the 60 species that fly around Britain every summer.
