This year, we found some tomato hornworms on the plants. Tomato hornworms are the larvae of hummingbird moths. The small yellowish-green eggs are laid underneath the leaves. The worms have a red-orange horn at the end of their bodies. They can be 2-4 inches long. The worms can devour most of a plant in 1-2 days. The worms are hard to find as they are almost the same color as the stem of tomato plants. Can you see it in the picture below?
The worms were extremly hard to pick off. We had to use pliers to yank them off the vines. We even considered cutting off the branch that they were on! The braconoid wasp will parasite some hornworms. The paracited worms look like they have rice grains on their bodies.
I hope that you will not have any problems with these hungry worms in your garden!
