[Note Guidelines] Photographer's Note
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.


Wing venationThis 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.[2].

Most if not all species of this genus, as usual for Coliadinae, do not sequester toxins or other noxious compounds from their food plants. They are therefore a well-loved prey item of insectivores as compared to Pieris of the related Pierinae. They make up this disadvantage by being more nimble and better able to evade attacks by would-be predators.[3]

Notable lepidopterologists who did many studies on this genus included J. Malcolm Fawcett, George B. Johnson and Henry Rowland-Brown.
