'British & Irish Butterfly Rarities' is the first book to focus solely on those butterfly species regarded as extinctions, rare migrants or introductions. There are 59 butterfly species that are considered resident or regular migrants to Britain and Ireland, yet there are another 63 species whose story deserves to be told.
The history of each extinct species, such as the Black-veined White and Large Copper, is spelled out, together with any reintroduction attempts.
