Tomato hornworm, also known as Manduca quinquemaculata, is a well-known pest that feeds on tomato plants and other members of the nightshade family. The term "tomato hornworm" is often used colloquially to describe any species of hornworm that attacks tomato plants, though there are other species that can cause similar damage. Some alternative names for this pest include Carolina sphinx moth, five-spotted hawkmoth, and tomato hawkmoth. Other hornworms that may be mistaken for the tomato hornworm include the tobacco hornworm, which has seven diagonal stripes and a red horn, and the plumed or white-lined sphinx moth, which has horizontal white lines and a curved horn.
