The story
The organisation was originally formed in 1968 as the British Butterfly Conservation Society by a small group of naturalists and it was registered as a charity on 7 March 1968. It was incorporated as a company on 17 December 1987, and changed its name to Butterfly Conservation in December 2003.
Sir David Attenborough became President of the society in 1998. It launched its annual butterfly survey - the Big Butterfly Count - in 2010. The charity celebrated its 50th anniversary year in 2018.
