The Madeiran large white (Pieris brassicae wollastoni) is a subspecies of the Large White, endemic to Madeira.[1] It can reach a size from 55 to 65 millimetres. The wings are pure white with a wide black tip on the apexes of the forewings. Its natural habitat is the laurisilva laurel forest.[2] Considering that it was last collected in 1977 but not found despite a 15-year survey during the 1980s and 1990s it might be either extremely rare or possibly extinct.[3] One reason for its decline might be a virus infection which brought out after the Small White (Pieris rapae) was introduced to Madeira in the 1950s.[4] The Latin name commemorates Thomas Vernon Wollaston, an entomologist who has discovered several insect taxa on Madeira.
