During what phase do nymphs look similar to adults in insects that undergo incomplete metamorphosis?

Insects that undergo incomplete metamorphosis, such as grasshoppers and true bugs, progress through three main life stages: egg, nymph, and adult. The nymph stage is crucial because it represents the juvenile form of the insect, which closely resembles the adult version in terms of body structure and general appearance.

During this phase, nymphs are not fully mature and may still be smaller in size and lack fully developed wings or reproductive organs, but they exhibit many of the same physical characteristics as adults. This similarity allows nymphs to be well-adapted to their environment, engaging in similar feeding habits and ecological roles as the adults.

In contrast, the egg phase is the initial stage, where the insect is encased within an egg and does not resemble the adult at all. The pupa phase occurs in insects that undergo complete metamorphosis (e.g., butterflies), where the insect drastically changes form and does not resemble the adult or larva. The larva phase, associated with complete metamorphosis as well, involves a distinct life stage (like caterpillars), which again differs in appearance from the adult.

Thus, the nymph stage is characterized by its resemblance to the adult form, making it the correct
