HD Tomato Hornworms / Five-Spotted Hawkmoth in Wisconsin – Devours Tomato Plants – Garden Pest!
The five-spotted hawkmoth (Manduca quinquemaculata) is a brown and gray hawk moth of the Sphingidae family. The caterpillar, often referred to as the tomato hornworm, can be a major pest in gardens. Tomato hornworms are closely related to (and sometimes confused with) the tobacco hornworm (Manduca sexta). This confusion arises because caterpillars of both species feed on the foliage of various plants from the family Solanaceae, so either species can be found on tobacco or tomato leaves, and the plant on which the caterpillar is found does not indicate its species.
When the caterpillars turn into the moth they are mistaken for humming birds because the way they flutter their wings so quickly (fastest month!)
Tomato hornworms are known to eat various plants from the family Solanaceae, commonly feeding on tomato, eggplant, pepper, tobacco, moonflowers and potato. Accordingly, they are often found on defoliated tomato plants, the caterpillar clinging to the underside of a branch near the trunk. They are difficult to spot due to their green coloration. Tomato hornworms fluoresce differently from tomato leaves. Using an ultraviolet light source of 375 nm and viewed behind a blue-blocking filter (yellow or amber filter), a tomato hornworm fluoresces in bright green while a tomato leaf appears deep red/amber. This sharp color contrast helps gardeners locate tomato hornworms at night. They can be reduced by planting marigold flowers around these plants.
