Tomato Hornworm
by Deborah Birge, Fort Bend County Master Gardener

This beautiful creature can be observed at dusk this time of year.  It hovers much like a hummingbird, from flower to flower taking nectar from flowers.  In fact, you may mistake it for a hummingbird since the wingspan is 4-5 inches and it moves quickly.

But, once you see the moth, keep an eye on your vegetable garden.  All tomato growers know the larval stage of this lovely moth … it’s the tomato hornworm.  Hornworms can quickly strip tomatoes, potatoes, eggplant and peppers of every leaf leaving damaged vegetables and weakened plants.

Life cycle

  • Moths live through the winter and emerge in spring. After mating, females deposit light green eggs on lower and upper leaf surfaces.
  • Caterpillars hatch, begin to feed and are full grown in three to four weeks.
  • The tomato hornworm blends in with green leaves.
  • The mature caterpillars drop off plants and burrow into soil to transform into pupae.
  • Moths emerge in two weeks to begin the second generation.
  • Second generation moths deposit eggs.
  • Caterpillars feed until late summer or early fall and then pupate.
  • Pupae remain in the soil through winter.
