The caterpillars (larvae) of the Five-Spotted Hawk Moth is a nuisance to agriculture. It is called the Tomato Hornworm. Don't be fooled by the name; this caterpillar eats more than tomato leaves. The green fleshy body almost fluoresces and has a single black needle-like spine (also called a horn) at its rear. Eight V-shaped marks lined both sides of the body. This is different from the caterpillar of the Tobacco Hornworm Moth which has 7 angled slashes on its body. The Five-Spotted Hawk Moth caterpillar is well camouflaged among the bright green leaves of tomato plants. They have voracious appetites and eat the leaves of tomatoes, potatoes, tobacco and other plants in the Solanaceae family. Removing a large percentage of the plants foliage in just a day or two allows the Tomato Hornworm to plump up rapidly. It also weakens plant production and health. They pupate and overwinter, emerging in the spring as winged adults. Removing the caterpillars by hand or with insecticides and preventing adults from laying eggs on the host plant by using row covers can help limit harvest loss.
