What stage follows the egg in the lifecycle of insects that undergo incomplete metamorphosis?

Insects that undergo incomplete metamorphosis progress through three main life stages: egg, nymph, and adult. After the egg hatches, the next stage is the nymph stage. Nymphs resemble miniature adults but typically lack fully developed wings and reproductive structures. They go through several molts as they grow, sometimes referred to as instars, gradually developing features resembling the adult form.

The other stages are not directly following the egg. The larval stage pertains to insects with complete metamorphosis, such as butterflies and beetles, where the lifecycle includes a larval form. The pupal stage is also specific to insects with complete metamorphosis, occurring after the larval stage and before the adult stage. The adult stage then follows the nymph stage in the lifecycle of those insects that undergo incomplete metamorphosis, but it does not directly follow the egg. Hence, the correct progression after the egg in this particular lifecycle is the nymph stage.
