A larva is an early stage in the life cycle of many insects, including butterflies, beetles, and moths. It typically follows the egg stage and is characterized by a soft, elongated body. Larvae often have distinct features that differ from the adult form, such as a lack of wings and a different diet. They primarily focus on feeding and growing during this stage. Larvae undergo a process called metamorphosis, where they transform into their adult form. This transformation can involve significant changes in body structure and function. Some larvae, like those of frogs, also play a crucial role in their ecosystems, serving as food for various predators while contributing to nutrient cycling.
