The following insects undergo incomplete metamorphosis except

Metamorphosis is the process of transformation that insects go through during their life cycle. Insects can undergo complete metamorphosis or incomplete metamorphosis. In complete metamorphosis, the insect goes through four distinct stages: egg, larva, pupa, and adult. In the larval stage, the insect looks very different from the adult and usually has a different diet and lifestyle. Examples of insects that undergo complete metamorphosis include butterflies, moths, beetles, and flies. In incomplete metamorphosis, the insect goes through three stages: egg, nymph, and adult. The nymph looks very similar to the adult, but is smaller and lacks wings. Examples of insects that undergo incomplete metamorphosis include grasshoppers, cockroaches, and termites. Therefore, the insect that does not undergo incomplete metamorphosis is the butterfly. Butterflies are an example of insects that undergo complete metamorphosis, where they go through the four stages of egg, larva (caterpillar), pupa (chrysalis), and adult (butterfly).
