What is a nymph in the context of insects?

In the context of insects, a nymph refers specifically to an immature form that closely resembles the adult insect but has not yet reached maturity. Nymphs are typically found in insects that undergo incomplete metamorphosis, such as grasshoppers and cockroaches, where they undergo a series of molts, gradually developing into adults. This means that while they look similar to the adults, they are usually smaller and lack fully developed wings and reproductive structures.

Understanding this concept is crucial for identifying life stages in insects, particularly when studying their life cycles and ecological impact. The distinction between nymphs and other life stages, like larvae or adults, is significant in pest management and entomology, as it influences control methods and strategies.
