A report in today's The Independent discusses the findings of Butterfly Conservation, which have shown that 11 species of butterfly broke their earliest-emergence records this year. This is nearly a fifth of all our regular species. Some species, including the Green Hairstreak, Chalkhill Blue and Lulworth Skipper showed as adults a month and a half early this year. Southern Britain's spring was effectively a month early.
