Incomplete metamorphosis is a type of a life cycle that insects undergo during their transformation. It is normally in three stages that include egg, nymph and adult, in that order.Continue Reading
Egg is the first stage of incomplete metamorphosis. After sometime, the egg hatches into a nymph. Nymphs are independent and almost similar to the adults but tend to be smaller in size and lack wings. In this stage, the nymph can share habitats with the adult in the same or different environments. They also feed on the same food and in the same way as the adults.
Nymphs normally have a thin layer of exoskeleton. As they develop bigger and heavier, they outgrow it. All insects undergo a process known as molting during which the old skin is left behind, and a new skin develops to form the exoskeleton. Molting occurs a number of times as an insect grows. After a number of molts, the wings start to appear and continuously increase in size as the insect becomes an adult.
The adult stage is the final one of in the incomplete cycle. In this stage, the wings function fully, and the insect can fly comfortably. The only difference between the nymph and the adult is the presence of the wings and their size.Learn more about Zoology
