Final answer:
In insects that undergo hemimetabolous or incomplete metamorphosis, the immature stages are called nymphs. These nymphs gradually develop their adult features, including wings and reproductive organs, through successive molts.
Step-by-step explanation:
The immature stages associated with hemimetabolous metamorphosis are typically known as nymphs. Hemimetabolous metamorphosis, also known as incomplete or gradual metamorphosis, is a type of development seen in certain insects like grasshoppers and crickets, where the immature stages resemble the adults but lack functional wings and reproductive structures. During successive molts, these immature stages, or nymphs, grow larger and gradually develop their adult features, including functional wings and reproductive organs, until they become adults.
It's important to note that the immature stages of insects that undergo complete metamorphosis (holometabolous), such as butterflies and beetles, are referred to as larvae rather than nymphs. These larvae differ significantly in structure and diet from their adult forms, and they undergo a transformation process (the 'pupa' stage) before becoming adults.
