Monarch Butterflies

During spring and summer, monarchs breed throughout the U.S. and southern Canada. In the fall, adults of an eastern population migrate to Mexico, flying up to 3,000 miles. The following spring, these butteries leave their overwintering sites and fly northward to lay their eggs on milkweeds and a few other plants in the dogbane family. In Florida, some non-migratory individuals remain and breed year-round.
