What is the second and third stage of the growth in a insect?

The second stage of insect growth is the larval stage, during which the insect often looks very different from its adult form and focuses on feeding and growing. The third stage is the pupal stage, where the insect undergoes a transformation, undergoing significant changes in structure and form to prepare for its adult life. This process is known as metamorphosis, and it varies among different insect species.
