Final answer:
The luna moth starts life as a caterpillar with green and yellow stripes, eats leaves from hickory and walnut trees, among others, and develops inside a cocoon.
Step-by-step explanation:
The luna moth, indeed, goes through significant changes throughout its life cycle. According to the passage, a luna moth begins its life as a caterpillar, not in a cocoon. During its caterpillar stage, it features green and yellow stripes and consumes leaves from specific trees, namely hickory, walnut, sweet gum, and birch trees. At the appropriate time, the luna moth caterpillar constructs a cocoon, within which it undergoes metamorphosis to become a moth.
