The Butterfly Red List for Great Britain. JNCC Species Status no. 12

This report has been produced as part of the Joint Nature Conservation Committee’s Species Status Assessment project and contains the first assessment of British butterflies against the new IUCN criteria (IUCN, 2001). Butterflies are known to be
one of the most rapidly declining groups of plants or animals (Thomas et al, 2004). All 62 resident and regularly breeding species (species that breed in Great Britain every year) were assessed, including three regular migratory species (Clouded Yellow Colias croceus, Red Admiral Vanessa atalanta and Painted Lady V. cardui).
