The term cabbage worm is primarily used for any of four kinds of lepidopteran whose larvae feed on cabbages and other cole crops. Host plants include broccoli, cauliflower, Brussels sprouts, collards, kale, mustard greens, turnip greens, radishes, turnips, rutabagas and kohlrabi. This small group of similar pest species is known to agriculturists as the cabbage worm complex.

• The imported cabbage worm is the green larva of the cabbage butterfly or cabbage white, any of several largely white butterflies (family Pieridae, type genus Pieris, garden whites). The Small White (P. rapae) is a small, common, cosmopolitan butterfly whose caterpillar has fine, short fuzz and is bright green; it prefers cabbage, broccoli and cauliflower. A larger Old World form (P. brassicae) is called Large White. A common North American form (P. protodice) is known as the southern cabbage butterfly. The green-veined white (P. napi) occurs in Europe and North America. In all of these species the larvae eat the leaves, which then become toxic to animals that consume the infested foliage.
