See large blue butterflies this summer

Large blue butterflies were extinct in the UK until reintroduced in

February 2011. Green Down Nature Reserve is home to the biggest number of Large Blue butterflies anywhere in the world, following their remarkable reintroduction by conservationists after UK extinction in 1979.

Green Down is closed throughout all of June and most of July to protect the butterflies when they are on the wing and laying eggs. An open day on 12 June will be your only chance to see Large Blue's during their flight period at the reserve.

Exclusive access via guided walks will be granted to a limited number of people. Numbers are restricted due to the sensitive nature of the site. Tickets cost £3.50 (adult) and £2 (child).

Apply by sending a letter and cheque, payable to Somerset Wildlife Trust, with your name and address in capitals, numbers of adults and children wanting tickets and a SAE, to Green Down Open Day, Somerset Wildlife Trust, Tonedale Mill, Tonedale, Wellington, Somerset, TA21 0AW.

The deadline for applications is 6 May. Successful applicants will receive their tickets in late May and everyone else will have their cheques returned.
