- A monarch caterpillar gains about 2,700 times its original weight, with a large caterpillar devouring an entire milkweed leaf in less than four minutes.

- Monarchs fly 2,000 miles or more to the cool moist fir forests in central Mexico.

- The first three generations of monarch butterflies live 6-8 weeks. Yet, the 4th generation-known as the “Super Generation” – lives about 8-9 months, migrating south, overwintering in Mexico and starting to fly the journey north in spring.
