What is a nymph in insects?
Quick Answer
A nymph is an immature insect that looks like a small adult but has not reached full size or sexual maturity. Nymphs develop by molting several times.
The Full Story
Insects with incomplete metamorphosis, such as grasshoppers, crickets, cockroaches, and true bugs, begin life as nymphs. A nymph resembles the adult form but is usually smaller, lacks fully developed wings, and cannot reproduce. As it grows, it molts repeatedly, gradually developing adult features. This type of development is different from complete metamorphosis, where the young stage often looks completely unlike the adult. Nymphs are important in ecology because they can occupy similar habitats to adults while still feeding and growing.
