Our tomato plants were covered in these guys, but oh well, I'd rather have squishy green caterpillars with eyeball markings than tomatoes any day. :P

They are called hornworms because, as many caterpillars in the Sphingidae family, they have a conspicuous horn or spine on the top of the last abdominal segment. The main difference between tomato and tobacco hornworms is their horn; the tomato have black horns while tobacco have red. They have five pairs of prolegs in addition to the thoracic legs and they have five instars. Manduca is the Latin word for "glutton", as one or two hornworms can easily defoliate a tomato plant.

Adults are large moths with long forewings. Their abdomen is marked with orange-yellow spots. They are strong fliers with a rapid wing beat and are sometimes mistaken for humming birds.
