Description

Colias From Wikipedia, the free encyclopedia Colias is a genus of butterflies in the family Pieridae. They are usually called clouded yellows; the North American name "sulphurs" is elsewhere used for Coliadinae in general. The closest living relative is the genus Zerene,[1] which is sometimes included in Colias. This genus occurs throughout the Americas, including the arctic regions. They are also found in Africa, China and India. Their caterpillars feed on certain Fabaceae, for example vetches (Vicia). While most are thus beneficial by keeping weeds at bay, some occasionally become nuisance pests on crops like alfalfa. In some species, the wings of males have brilliant UV reflection, while those of females do not http://en.wikipedia.org/wiki/Colias Good night and good week Thanks for the comments and the favourites of previous image
