What is the primary role of the larval stage in complete metamorphosis?

The primary role of the larval stage in complete metamorphosis is to feed and grow. During this phase, the organism undergoes significant growth and development, consuming large quantities of food to build the energy reserves necessary for the next stage of its life cycle. The focus on feeding allows the larva to grow in size and prepare for the transformation into the pupa stage, where it will undergo further physiological changes. This stage is critical for the organism's development, resulting in a dramatic transformation into the adult form, which will later be responsible for reproduction. The larval stage is not about resting, reproducing, or developing wings; those functions are associated with later stages in the lifecycle.
