Some tagged monarchs have been found to travel more than 2,000 miles. When it rains, butterflies find shelter in trees, shrubs or tall grasses. Many may die in a big storm. Some types of butterflies spend the winter in the pupal stage. They may be pupae for six to eight months.
Butterflies have many enemies.
Certain flies and wasps lay their eggs in or on the caterpillar. When the eggs hatch, the small fly larvae eat the caterpillar. Dragonflies and birds also eat large numbers of caterpillars. Spiders catch them in their webs. Adult butterflies are also attacked by birds, frogs, toads and lizards.
