In gradual metamorphosis, what stage follows the egg?

In gradual metamorphosis, the life cycle consists of three main stages: egg, nymph, and adult. After the egg hatches, the next stage is the nymph. This stage resembles a smaller version of the adult but lacks fully developed wings and reproductive systems. The nymph will go through several molts, growing larger each time and gradually taking on the adult characteristics.

The other stages mentioned—pupa and larva—are part of complete metamorphosis, which involves a different developmental process. In complete metamorphosis, insects transition through an egg, larva, pupa, and then into the adult stage, which is not applicable here. Hence, in the context of gradual metamorphosis, the nymph stage is indeed the correct answer that directly follows the egg stage.
