Founded in 1981, the Yorkshire Branch of Butterfly Conservation is one of the largest geographically as the county of Yorkshire measures approximately 150km north to south and 170km east to west!

From its humble beginnings with eighteen members, the branch has grown steadily to almost a thousand members today.

The branch works closely with the Yorkshire Naturalists' Union and promotes the jointly administered but independent recording scheme known as ButterflyNet Yorkshire, with a co-ordinator in each of Yorkshire's five vice counties and species co-ordinators for the county as a whole.

The branch magazine Argus is published regularly and details of both it and our other publications can be found on the publications page.
