Madeiran large white – is a subspecies endemic to Madeira, reaching a size from 55-65 mm. 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. The most probable 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.
The original design was made primarily for being printed as a poster, but you can find modified versions – more suitable for t-shirts, hoodies etc. – in my store:
