They are one of the most common types of worms you will see on your tomato plants. They are the larvae form of the five-spotted hawkmoth.
Tomato hornworms are recognizable by their chevron stripes and black horn on the backside of their green bodies. Both types like to eat tomatoes, tobacco, potatoes, eggplants, peppers, and other types of nightshade plants. There are two main types of hornworms, tomato hornworm, and tobacco hornworm. They can consume the leaves and other parts of tomatoes at a fast rate, so it is best to get rid of them as soon as you notice them. They are generally brown or green in color, which lets them easily blend into your tomato plant. These worms that you see on your tomato plants are actually either the larval stage of moths or caterpillars.
