Insects that develop by complete metamorphosis?

Insects that undergo complete metamorphosis, known as holometabolism, transition through four distinct life stages: egg, larva, pupa, and adult. In this process, the larval stage is crucial for the growth and development of the insect. During this stage, larvae actively feed, grow, and molt in order to accumulate the necessary energy and resources for the subsequent pupal stage. This feeding behavior is vital, as it prepares the organism for transformation into the adult stage, where it will reproduce and contribute to the life cycle.

The correct answer highlights the significance of the larval stage in complete metamorphosis, emphasizing that this stage is characterized by active feeding and growth. This is in contrast to other options which do not accurately reflect the biological processes involved in complete metamorphosis. Some insects may skip certain stages, but this does not apply universally to all insects that undergo complete metamorphosis. Thus, the feeding and growth of larvae are fundamental to understanding the life cycle of these insects.
