Identifying the Entire Lifecycle The tomato hornworm develops into a five-spotted hawk moth that lays its eggs on the underside of the foliage. Carefully look along stems, lifting leaves to find the hornworms underneath. As they get larger, hornworms are easier to see, but they will have already done quite a bit of damage. They are very well camouflaged against the leaves and stems and can be quite hard to see while still small.Ī telltale sign that you’re dealing with a hornworm is seeing a branch or portion of a branch with no leaves in the morning.

These large caterpillars will eat non stop and can quickly defoliate an entire tomato (or peppers, eggplant, and potatoes) plant.
