Which moth has a caterpillar commonly called the tomato hornworm?

Manduca quinquemaculata is the moth whose caterpillar is commonly called the tomato hornworm.

The tomato hornworm is the larval stage of a large hawkmoth native to North America. Its caterpillars commonly feed on tomato plants and other members of the nightshade family, including potato, pepper, and tobacco relatives.

The adult moth is often called the five-spotted hawkmoth, referring to the five orange-yellow spots along each side of its abdomen. After feeding and growing, the caterpillar burrows into soil to pupate before emerging as an adult.

A frequent mix-up is Manduca sexta, whose larva is the tobacco hornworm. The two species are closely related and can look similar, but their common names reflect different host plants and identifying patterns.
