What are the three stages of incomplete metamorphosis?

The three stages of incomplete metamorphosis are indeed the egg, nymph, and adult. Insects that undergo incomplete metamorphosis develop through these distinct phases.

Initially, the life cycle begins with the egg stage, wherein the female lays eggs. Once the eggs hatch, the nymph stage begins. Nymphs resemble smaller versions of the adult insects but often lack fully developed wings and reproductive structures. As nymphs grow, they molt several times, resulting in several instars until they reach the final adult stage. In this adult form, insects acquire their full body structure, including wings and the ability to reproduce.

Insects that follow this life cycle pattern include grasshoppers and cockroaches, contrasting with complete metamorphosis, which includes larva and pupa stages. Understanding these stages is essential for pest control technicians, as it helps in identifying the life cycle of various insect pests, thereby informing appropriate management strategies.
