Cabbage White (Pieris rapae)
Everybody knows this one – a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. Accidentally introduced to North America a couple of centuries ago. The species can be found in any open area with diverse plant association. It can be seen usually in towns, but also in natural habitats, mostly in valley bottoms. Although an affinity towards open areas is shown, the small white is found to have entered even small forest clearings in recent years.
Caterpillars can be a pest on cultivated cabbages, kale, radish, broccoli, and horseradish
