After 50 years of trying to prevent its decline, the Large Blue Butterfly (Maculinea arion) was eventually pronounced extinct in the UK in 1979. After a number of years of careful habitat management, the 1984 reintroduction of the Large Blue Butterfly at two UK sites has been a huge success.  This example was photographed on Daneway Banks in Gloucestershire, UK.
