Do you live in Iowa and have an insect you would like identified? When hornworms are observed, handpicking is usually sufficient control action. Carefully watch for larvae and feeding from June to harvest. Parasitism and other natural factors keep hornworm populations sufficiently low in most gardens.
Hornworms blend in with the foliage and are difficult to see until much defoliation has occurred. Ravenous leaf feeding by hornworm larvae may result in extensive defoliation. A hornworm can eat a considerable amount of foliage that may look like severe damage, but actual yield loss is probably slight. The well–known tomato hornworm is more often a curiosity in gardens rather than a pest, though outbreaks have been known to occur. The larvae feed on the foliage for 4 to 5 weeks before growing to the commonly–seen size of 3 to 4 inches long. The adult hawk moths emerge in mid- to late June and lay eggs on the lower side of host plant leaves.
The insect spends the winter in the soil as a large, brown pupa.
Both species have diagonal white stripes along the sides of the body. The short, slender horn on the tip of the abdomen is red on the tobacco hornworm and green on the tomato hornworm.
