[QUOTE="Dodge Man, post: 2422148, member: 2062"] [url=http://www.vegedge.umn.edu/vegpest/hornworm.htm]http://www.vegedge.umn.edu/vegpest/hornworm.htm[/url] The adult moth, sometimes referred to as a "sphinx", "hawk", or "hummingbird" moth, is a large, heavy-bodied moth with narrow front wings. The moth is a mottled gray-brown color with yellow spots on the sides of the abdomen and a wing spread of 4 to 5 inches. The hindwings have alternating light and dark bands. Eggs of the tomato hornworm are deposited singly on both the lower and upper surface of leaves in late spring. The eggs hatch in six to eight days and are oval, smooth, light green to yellow in color, and measure 0.10 cm in diameter. Larvae are pale green with white and black markings (see photo), and undergo 5-6 instars. The first instar is yellow to white in color with no markings. Later instars develop eight white, lateral "V-shaped" marks. A black projection or "horn" on the last abdominal segment gives the caterpillar the name "hornworm." The caterpillar reaches the final instar in 3-4 weeks, and is 3 1/2 to 4 inches when fully mature. Fully-grown larvae then drop off of the plants and burrow into the soil to pupate. During the summer months, moths will emerge from pupae in about 2 weeks. Moths emerge from the soil, mate, and then begin to deposit the eggs of the next generation on tomato plants. By early fall, the pupae will remain in the soil all winter and emerge as a moth the following spring. [/QUOTE]
