Butterflies and moths undergo complete metamorphosis: egg, larva, pupa, and adult. The larvae, commonly known as caterpillars, have chewing mouthparts.

Noctuidae (cutworm moths). The Noctuidae is a large including species of economic importance like armyworms, cutworms, bollworms, and loopers. They are primarily foliage feeders, but many species also consume stems and fruits.

Pyralidae (snout and grass moths). The small moths of this family have a prominent snout (labial palps) and are commonly found in grassy areas, like the European corn borer.

Sphingidae (sphinx moths). The larvae of sphinx moths almost always have a spinelike projection on their eighth abdominal segment and, therefore, are commonly known as hornworms. These foliage feeders are a threat to many solanaceous crops.
