10 Amazing Facts About The Monarch Butterfly
- The adult female monarch butterfly lays tiny eggs covered with a sticky substance on the underside of milkweed leaves, which are extremely toxic. The caterpillar hatches from its egg several days later and survives on these milkweed leaves.
- The monarch caterpillar and adult butterfly retain the poison from the milkweed leaves in its body, thus protecting it from being eaten by predators.
- Every spring, adult monarch butterflies head north from their winter respite in the southern forests of Mexico and California, and return in the fall—a journey some 2,000-3,000-miles each way!
- The monarch butterfly will continue to feed, fly, and reproduce throughout the U.S. and southern Canada, for several generations. It is the fourth generation of monarch butterflies that actually migrate to Mexico in fall.
