Tomato hornworms can cause significant damage to gardens, particularly to tomato plants. Understanding The Devastation of Tomato Hornworm Infestations The life cycle of a tomato hornworm begins as an adult moth known as a hummingbird moth or sphinx moth, which has gray-brown mottled wings with yellow spots on the sides of its abdomen and alternating light and dark bands on its hind wings.Īdditionally, using a UV flashlight is an effective way to locate them as they glow under its rays while also looking for wilted hanging leaves and stems that have lost part of their leaves, as these could be nearby host sites for these pests. However, they can easily be overlooked thanks to their ability to blend in with the foliage. Though harmless, the sight of it can be frightening. They are easily identifiable due to their large size (3-5 inches long), light green bodies with white and black spots, V-shaped stripes, and long black horn that sticks out of their rear end. Tomato hornworms are an omnipresent and destructive pest to gardeners growing tomatoes, eggplants, peppers, and potatoes. However, they can easily be distinguished by these unique features. These two species may be mistaken for each other at first glance due to their similar appearance. The adult form of this species is known as the tobacco hawk moth or Carolina sphinx moth. In contrast, the tobacco hornworm has seven white diagonal stripes on its body and a red horn instead of black.
