Butterfly distributions for Scotland from Butterfly Conservation and the Biological Records Centre

Scottish butterfly distribution data from the Butterflies for the New Millennium (BNM) project, the national recording scheme for butterflies, run by Butterfly Conservation, in association with the Biological Records Centre (BRC). This data set consists of 400,000 distribution records of butterflies collected by volunteers. The data include records of all resident butterfly species plus three regular migrants (Clouded Yellow Colias croceus, Red Admiral Vanessa atalanta and Painted Lady V.cardui). Records were made from all terrestrial habitats and throughout the year.
