If your vegetable garden includes tomato plants, there’s a good chance that it will attract the attention of the pesky tomato worm at some point. The tomato hornworm caterpillar is a greenish caterpillar measuring about 4 1/2" long. It has a spike or "horn" on its tail, giving this insect pest its name. Tomato worms can be found in just about every region of the United States, and they can wipe out your plants in no time at all.
Holes in the leaves, fruit and stems of tomatoes, peppers, and eggplants may indicate the presence of the tomato hornworm.
So... What's a Tomato Hornworm?
The tomato hornworm caterpillar is a greenish caterpillar measuring about 4 1/2" long. It has a spike or "horn" on its tail, giving this insect pest its name.
The larval stage of the tomato hornworm is the only destructive stage since it feeds on the leaves, fruit and stems of plants.
Reproduction Patterns of Tomato Hornworms
Adult moths will lay eggs in late spring. After the eggs hatch in about 6-8 days, the larvae will go through development in stages that last up to four weeks.
Then they will go below ground to spend the winter in the pupal stage, emerging in June or July of the following year as adult moths known as sphinx or hawk moths.
