Verified step by step guidance

1. Understand that complete metamorphosis in insects involves a distinct transformation process with four stages.
2. The first stage is the 'Egg' stage, where the insect begins its life cycle.
3. The second stage is the 'Larva' stage, where the insect hatches from the egg and is in a feeding and growing phase.
