Incomplete metamorphosis is a type of development seen in certain insects, such as grasshoppers and cockroaches. In this process, the young insects, called nymphs, resemble smaller versions of the adults. They grow and molt several times, gradually developing into their adult form without a distinct pupal stage. During each molt, nymphs shed their exoskeletons, allowing them to grow larger. This process continues until they reach maturity, at which point they can reproduce. Incomplete metamorphosis is different from complete metamorphosis, where insects undergo distinct life stages, including a larval and pupal stage before becoming adults.
