4. How Much A Caterpillar Eats Helps It As A Butterfly During Migrations

One of the most remarkable features of a butterfly is for all of the movement it does in one day, and it really doesn’t eat that much. Part of this reason is that they are so busy flying that they don’t stop to eat. Another part is because they eat so much as a caterpillar that they are still using this food for fuel throughout their weeks as a butterfly. 

It isn’t that the monarch butterfly doesn’t eat; they do take time to feed. They simply don’t eat as much as they did as a caterpillar. A butterfly’s whole migrational life is spent flying, feeding, and reproducing.
