British butterflies suffer devastating year after 2012's wet summer
Patrick BarkhamFewer butterflies flew in British skies in the miserable summer of 2012 than for thousands of years, leaving several species in danger of extinction from parts of the country.
The country's most endangered butterfly, the high brown fritillary, saw its small population slump by 46%, while another rare species, the black hairstreak, fell by 98%, as 300,000 fewer butterflies were recorded on the wing compared with 2011.
The wettest ever year recorded in England was equally damaging for once common species: of 56 native species monitored, 52 saw their numbers decline from the previous year, with big losses for once-ubiquitous small tortoiseshell, common blue and large and small whites.
