Cabbage White Butterfly

Cabbage White Butterfly
The Small White (Pieris rapae) is a small- to medium-sized butterfly species of the Yellows-and-Whites family Pieridae. It is also commonly known as the Small Cabbage White. The names “Cabbage Butterfly” and “Cabbage White” can also refer to the Large White.

It is widespread across Europe, North Africa and Asia and has also been accidentally introduced to North America, Australia and New Zealand where they have become pests on cultivated cabbages and other mustard family crops. Cabbage White Butterfly Description
In appearance it looks like a smaller version of the Large White. The upperside is creamy white with black tips to 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-looking appearance. An adult’s wingspan is roughly 32–47 mm (1.25–2 in). Cabbage White Butterfly Life cycle
In Britain, it has two flight periods, April-May and July-August, but is continuously-brooded in North America, being one of the first butterflies to emerge from the chrysalis in spring, flying until hard freeze in the fall.

Its caterpillars can be a pest on cultivated cabbages, kale, radish, broccoli, and horseradish but it will readily lay eggs on wild members of the cabbage family such as Charlock Sinapis arvensis and Hedge mustard Sisybrium officinale. The eggs are laid singularly on food-plant leaves.

Traditionally known in the United States as the “Imported Cabbage Worm”, now more commonly the “Cabbage White”, the caterpillars are green and well camouflaged. Caterpillars rest on the undersides of the leaves, thus making them less visible to predators. Unlike the Large White, they are not distasteful to predators like birds. Like many other “White” butterflies, they hibernate as a pupa. It is also one of the most cold-hardy of the non-hibernating butterflies, occasionally seen emerging during mid-winter mild spells in cities as far north as Washington D.C.

Like its close relative the Large White this is a strong flyer and the British population is increased by continental immigrants in most years. Adults are diurnal and fly almost exclusively during mid-day, though it appears as if there is some activity in the later part of the night too, ceasing as dawn breaks.
