The Madeiran large white (''Pieris brassicae wollastoni'') is a subspecies of the Large White, endemic to Madeira.〔John Feltwell: ''Large white butterfly: The Biology, Biochemistry and Physiology of Pieris Brassicae (Linnaeus)''. Springer, 1982 ISBN 90-6193-128-2〕 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.〔(''Pieris brassicae wollastoni'' )〕 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.〔(Man drives butterfly into extinction and it could be bad news for us too )〕 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.〔Gardiner, B. (2003) ''The possible cause of extinction of Pieris brassicae wollastoni Butler (Lepidoptera: Pieridae)''. Entomologist's Gazette 54:267–268〕 The Latin name commemorates Thomas Vernon Wollaston, an entomologist who has discovered several insect taxa on Madeira. == References ==
