I've been searching the Internet for an official list of all Butterflies ever recorded in Britain, but each website (From Wikipedia to UK Butterflies) seem to have different numbers of species on their lists. Some suggest 80 have been recorded in an apparently natural state, with some now extinct, whilst another one I found said only 72 had ever been recorded.
Does anyone have a link to, or know of, any official list of Butterflies ever recorded in Britain, or does it just vary dependant on whose list you choose to read?
Cheers.
