7th March 1968.
Today the British Butterfly Conservation Society was registered as a charity. One of its founders was Peter Scott.
Butterflies said to have benefited from conservation are the Chalkhill Blue, one of the largest in Britain, the Silver-Spotted Skipper and Dark Green Fritillary.
However a survey since 1995 noted that the formerly widespread, High Brown Fritillary, one of the native species to found in Britain, are now rarities, but common varieties such as the Speckled Wood have benefited from recent warm years and spreading northwards.
In 2002 after a three-year study by the butterfly conservation ten of the thirteen species dependent on specific habitats had done better under the grants offered by Countryside Stewardship schemes by leaving field-edges and changing summer grazing patterns. But the final arbiter will be economics and the need to feed a growing population.
The Large Blue, discovered in Britain 1795 is a success story as it was extinct before being reintroduced and shows the complicated symbiosis of some species as it feeds on thyme and marjoram.
This butterfly also has a unique parasitic relationship with the Myrmica Ant which is tricked into taking the larvae into its nest which then feed on the eggs and larvae.
Butterflies might have been thicker on the ground in the 19thc when Tess Durberville had to be carried over a flood, ‘catching butterflies in her billowing skirts’…(1)
