hornworm

A hornworm is the caterpillar of a hawk moth, characterized by a horn-like tail process. These larvae are typically smooth-bodied and feed on plants. Some hornworm species, such as the tobacco hornworm (Manduca sexta) and the tomato hornworm (M. quinquemaculata), are considered significant pests in North America, damaging crops like tomatoes, tobacco, and potatoes.12

Hornworms are green and can grow up to 10 cm (4 inches) long. Their larval stage is relatively simple compared to the specialized adult moth. Control methods for these pests include introducing natural enemies like the braconid wasp (Apanteles congregatus), which parasitizes the larvae. After the larval stage, they pupate in the soil.23
