Hornworms have a habit of beginning their eating towards the top of the plant; search for leaves that have been bitten or are missing. Examine the very top of the tomato leaves carefully for any dark green or black droppings that may have been left behind by the larvae that are eating on the leaves. The next step is to examine the undersides of the leaves, where you will probably locate hornworms.
Can you find hornworms with a black light?
Under a blacklight, the tomato hornworm, one of the most fascinating insects that may cause damage to tomatoes, can sparkle.

Home gardeners would like the fact that this shining makes it significantly simpler to control pests.
What month does the tomato hornworm turn into?
Tomato hornworms spend the winter dormant in the form of pupae and transform into adult moths in the spring.

In around three to four weeks after hatching, caterpillars begin feeding and develop into fully fledged adults.
