What is the newly hatched, wingless form of many insects called?

The newly hatched, wingless form of many insects is called larvae. This developmental stage is characteristic of insects that undergo complete metamorphosis, such as butterflies and moths. During this stage, larvae primarily focus on growth and feeding, as they typically have different physical characteristics and behaviors compared to their adult forms. This distinct phase allows them to effectively consume resources and prepare for the next stage of their life cycle, where they will enter the pupal stage before emerging as adults.

In contrast, Lepidoptera refers specifically to the order of insects that includes butterflies and moths, which are generally recognized by their scaled wings as adults. Insecta is the class that encompasses all insects, including a vast diversity of forms and life cycles. Fauna refers to all animal life in a particular region or habitat and does not pertain specifically to insect development stages. Thus, larvae is the most accurate term for the juvenile stage of many insects.
