Pieris rapae

Pieris rapae is a small to medium sized butterfly in the whites and yellows family Pieridae. It is known by different common names in different regions: the small white in Europe, the cabbage white or cabbage butterfly in North America and the United Kingdom, the small cabbage white on several continents, and the white butterfly in New Zealand. The butterfly is white with small black dots on its wings, and it can be told apart from the related Pieris brassicae by its smaller size and the absence of a black band at the wingtip.
