What are larval insects characterized by?

Larval insects are characterized by their developmental stage, which often looks significantly different from the adult form. In many species, larvae do not resemble adults in terms of body structure, size, and ecological role. For instance, a caterpillar, which is the larval stage of a butterfly or moth, has a shape and function that are quite different from that of the adult butterfly, including various feeding habits and habitats.

This diversity in appearance and behavior is a critical aspect of an insect's life cycle, allowing larvae to exploit different ecological niches or resources than the adults, which often leads to reduced competition for food and space. The distinct characteristics of larval forms help adapt them to specific environments to ensure survival and growth before they undergo metamorphosis into their adult stage.
