Pieris rapae
Some plants and animals have habitat requirements which are met in a wide range of locations. The small white butterfly "Pieris rapae" for example is found on all the continents of the world apart from Antarctica. Its larvae feed on a wide range of "Brassicas" and various other plant species, and it thrives in any open location with diverse plant associations. The large blue butterfly "Phengaris arion" is much more specific in its requirements; it is found only in chalk grassland areas, its larvae feed on "Thymus" species and because of complex lifecycle requirements it inhabits only areas in which "Myrmica" ants live.
