Where do horned tomato worms come from?
They are the larvae of the "Tobacco Sphinx Moth" a very large night flying insect. Their wingspan can be up to 5" from wing tip to wing tip. The reason you haven't seen it up until now, is that it was very small after hatching from eggs laid on the leaf by the adult moth. As it eats and gorges itself on your tomato plant, it begins to grow very fast. After a couple of weeks, that little larvae that was unnoticeable on the plant, is now a big, fat, green caterpillar devouring every bit of green matter it can get its mandibles on. Hope this answers your question.

Reply:Tomato horned worms are the larvae of the sphinx/hawk moth. The moths fly at night, so you seldom actually see them. Most people simply pluck the worms (actually caterpillars) off the plants an squash them. If you have a couple of plants that are already destroyed, put them on those, and they will have the chance to develop into moths.
Reply:They are the catipillar that will turn into a moth. So they come from a moth.
Reply:They come from - that is they will turn into - sphinx moths which are gray or brown unattractive moths.
Reply:Tomato hornworms are the larvae of a species of Sphinx moth (aka hummingbird moth). Handpicking will control them.
