Tomato Hornworm
(John Obermeyer, Purdue University)
spacer
Common Name: Tomato Hornworm

Order: Lepidoptera

Family: Sphingidae


Pest Status: Tomato hornworms can be very damaging to certain plants, especially tomatoes.

Appearance: Tomato hornworms are nearly identical to tobacco hornworms with the small exception of having five rather than six yellow spots on each side of the abdomen.

Life Cycle: The life cycle is also nearly identical. The unique caterpillars are large, green and have a distinct "horn" protruding from the rear.

Where to Collect: Hornworms are very fast fliers and may look like hummingbirds, hovering in front of flowers as they insert their long mouthparts.
