hemimetabolisme

Hemimetabolism, also known as incomplete metamorphosis, is a type of insect development where the young, called nymphs, gradually resemble the adult form. Unlike holometabolism (complete metamorphosis), there is no pupal stage. The insect hatches from the egg as a nymph, which looks like a smaller version of the adult but lacks fully developed wings and reproductive organs. As the nymph grows, it sheds its exoskeleton several times in a process called molting. Each molt brings the nymph closer to the adult form, with wings becoming more prominent and reproductive structures developing. The final molt results in the imago, or adult insect. This developmental pattern is observed in insects such as grasshoppers, cockroaches, dragonflies, and true bugs. The nymph typically inhabits the same environment as the adult and often shares a similar diet, although some species may have slightly different feeding habits or ecological niches during their nymphal stages.
