The distribution of colias in the equatorial andes

Abstract

The Genus Colias of primarily yellow and orange Pierid butterflies, is largerly northern in distribution. Representatives are found from Europe across the great Eurasiatic land mass to Siberia and northern Japan from where they span the narrow water barrier separating America and occur throughout North America. In the Mediterranean region, representatives are found on both the European and the African shores of the sea and also are found south around the Sahara desert through the highlands of Ethiopia and the Sudan into the southern parts of that continent, being absent in the hotter and more humid places.
