Pieris rapae
The small white (''Pieris rapae'') is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is also known as the small cabbage white and in New Zealand, simply as white butterfly. The names "cabbage butterfly" and "cabbage white" can also refer to the large white. The butterfly can be distinguished by the white color with small black dots on its wings. They are distinguished from the smaller size and lack of the black band at the tip of their forewings.
It is widespread and populations are found across Europe, North Africa, Asia, and Great Britain. It has also been accidentally introduced to North America, Australia and New Zealand. The caterpillar of this species is seen as a pest for commercial agriculture. Often referred to as the "imported cabbageworm" they are a serious pest to cabbage and other mustard family crops.
==Description==
In appearance it looks like a smaller version of the large white (''Pieris brassicae''). The upperside is creamy white with black tips on the forewings. Females also have two black spots in the center of the forewings. Its underwings are yellowish with black speckles. It is sometimes mistaken for a moth due to its plain appearance. The wingspan of adults is roughly 32–47 mm (1.25–2 in).〔http://www.cbif.gc.ca/spp_pages/butterflies/species/CabbageWhite_e.php〕
