Absolutely Fantastic Histo! Up here in WI, I always thought they were Tobacco Hornworms and when you said Tomato Hornworm, I had to do some research wondering what the difference was. Well, Wikipedia answered the question!
"The caterpillar, often referred to as the tomato hornworm, can be a major pest in gardens. Tomato hornworms are closely related to (and sometimes confused with) the tobacco hornworm (Manduca sexta). The larvae of these species can be distinguished by their lateral markings: tomato hornworms have seven V-shaped markings while tobacco hornworms have seven diagonal lines."
