Butterfly distribution records for the UK from Butterfly Conservation, up to 2019

UK butterfly distribution data from the Butterflies for the New Millennium (BNM) recording scheme, run by Butterfly Conservation. This dataset comprises occurrence records of butterfly species collected by volunteers, professionals and the public. The data include records of all resident butterfly species plus natural migrants, but exclude adventive species. Records were made from a wide range of terrestrial habitats and throughout the year and were collated from multiple source datasets or surveys. All records were checked by local taxonomic expert volunteers (County Recorders) prior to inclusion. Records are presented at 2km x 2km (tetrad) grid square resolution (unless deemed to be sensitive records).
