The monarch butterfly is a insect. It lives in fields and meadows across North America. This place is wide and open.
The monarch butterfly eats flower nectar and milkweed leaves. It flies up to 4,000 kilometers south to Mexico each autumn.

Baby monarch butterflies are called caterpillars. Caterpillars eat only milkweed, which makes their bodies poisonous to birds.
