Detailed explanation-1: -Incomplete metamorphosis is a type of metamorphosis in which an insect hatches from an egg and then goes through several nymphal stages. Each nymphal stage looks like a small version of the adult but getting slightly bigger with age. At the final nymphal stage the insect then moults into the adult form.

Detailed explanation-2: -Nymph: The immature form of insects with simple metamorphosis. (Stages between molts of the exoskeleton are called instars). Simple Metamorphosis: Heteroptera (True Bugs)

Detailed explanation-3: -In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph’s overall form already resembles that of the adult, except for a lack of wings (in winged species).

Detailed explanation-4: -nymph, in entomology, sexually immature form usually similar to the adult and found in such insects as grasshoppers and cockroaches, which have incomplete, or hemimetabolic, metamorphosis (see metamorphosis). Wings, if present, develop from external wing buds after the first few molts.

Detailed explanation-5: -The three insect orders with incomplete metamorphosis (hemimetabolous) are Ephemeroptera, Odonata, and Plecoptera. The Odonata are further divided into two suborders, Anisoptera (dragonflies) and Zygoptera (damselflies).
