Every child learns about the life cycle undergone by most insects — the four stages of egg, larva, pupa, and adult.
You may have gone hunting for and found all four stages on a nature hike. Looking for butterflies at the various stages is especially popular.
Artists through the ages have used them as models and incorporated them into paintings and sculpture.

Have you ever…tried to compare this to humans? Think for a moment.
Egg — before birth yet very much alive.
Larva — children are always hungry and refuse to stay in one place
Pupa — teens (have you ever tried to wake one early in the morning?)
Adult — a magical moment, or short time span, where the previous stage gives way to rational thought and dependable actions (every parent’s wish)
