Cabbage worm

• The small white 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 is called large white. A common North American form is known as the southern cabbage butterfly. The green-veined white occurs in Europe and North America.
• The cabbage looper is a member of the moth family Noctuidae. The caterpillar is smooth and green with white stripes. It is called a "looper" because it arches its body as it crawls, inchworm style. This species is very destructive to plants due to its voracious consumption of leaves. It is not restricted to cole crops; other plant hosts include tomato, cucumber, and potato. The adult of the species is a nocturnal brown moth.
• The cabbage webworm is a widely distributed webworm native to southern Europe or Asia that also injures cabbages and other vegetables in the Gulf states of the United States.
• The diamondback moth is a member of the moth family Plutellidae. The caterpillar is smooth and solid green in color. When disturbed, it thrashes and drops off the plant. The newly emerged larva is a leaf miner, entering the tissues of the leaf and consuming the parenchyma between the two outer layers of the leaf. Larger larvae make holes through the leaf, consuming all the tissue. The adult of the species is a small, elongated gray moth with whitish spots on the forewings that form two diamond shapes when the moth is at rest. The diamondback moth is primarily a tropical species, but is migratory, reaching temperate zones in most years.
