tobacco hornworm
Manduca sexta (Linnaeus)

Host: flue-cured tobacco (Nicotiana tabacum (flue-cured type) L.)
Descriptor: Larva(e)
Description: Tobacco and tomato hornworms [Manduca sexta (Linnaeus), Manduca quinquemaculata (Hawthorn)]: These two species, usually referred to collectively as "hornworms," are potentially the most destructive insect pests of tobacco. Newly hatched larvae are ¼ inch long, pale green with a large horn at the posterior end. Larger larvae (up to 3 or 4 inches) are bright green in color. Tobacco hornworm larvae have seven white diagonal stripes on each side and a curved red horn. Tomato hornworms have eight white V-shaped marks on each side and the horn is straighter and blue-black. Small larvae chew small irregular holes in leaves. Larger larvae more often feed on leaf margins and may leave only the midribs of leaves.
