Which type of metamorphosis do roaches exhibit?

Roaches exhibit gradual metamorphosis, also known as incomplete metamorphosis. In this type of development, the life cycle consists of three stages: the egg, the nymph, and the adult.

After hatching from the egg, the nymph resembles a smaller version of the adult roach but lacks fully developed wings and reproductive structures. As the nymph grows, it undergoes several molts, shedding its exoskeleton to accommodate its increasing size. This process continues until the nymph reaches maturity, at which point it becomes an adult capable of reproduction.

The gradual development allows for a more straightforward transition between stages, making it easier to observe the changes in size and morphology, unlike complete metamorphosis, where insects undergo distinct larval, pupal, and adult stages. Understanding this process is crucial for pest management strategies, including the life cycle's impact on population control.
