Pyle adds (pg.141) thatRobert Michael Pyle wrote: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Chew has shown conclusively that Cabbage Whites are tolerant of anthropogenic conditions, while the native whites have withdrawn before development and agriculture; and that some introduced crucifers attract oviposition, but prove lethal to larvae.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 [European] Cabbage butterflies have become a scapegoat for habitat displacement brought about by people.
Personally, I think they're a lot prettier up close than far away. Your picture is a great example!I have great respect for the Cabbage Butterfly. ... It is quite pretty, very abundant, ubiquitous, and exceedingly adaptable. ... It didn't force out native whites, as the folk tale holds; rather, we made the habitat suitable for the alien and unacceptable for the native. The Cabbage White is here to stay, so we might as well enjoy it.
