Mike, I'll bet if you saw the topside of the wings, you'd call it a "sulphur". They're bright yellow, sometimes tending toward orange. Colias is the North American genus too. These things are closely related to the cabbage butterflies -- different genera in the same family.Mike B in OKlahoma wrote:...I'd call a cabbage butterfly in America.
Nikola, sorry for taking over your topic for a moment to give a mini-lecture on butterfly ecology, but somehow it just seemed appropriate.(pg.139) Authors have alleged for decades that our native species of Pieris have retreated as a direct result of competitive exclusion by introduced Cabbage Whites. There's no doubt that some have diminished. But research by Francie Chew has shown conclusively that Cabbage Whites are tolerant of anthropogenic conditions, while the native whites have withdrawn before development and agriculture; and that some introduced crucifers attract oviposition, but prove lethal to larvae. Thus Cabbage butterflies have become a scapegoat for habitat displacement brought about by people.
