During their annual migration to warmer weather, a monarch butterfly that was tagged in Dallas County has finally made its way to Mexico.

According to the Iowa DNR, it took this butterfly 39 days and some-1,800 miles to reach its destination.

The monarch is the only butterfly known to make a two-way migration as birds do.

During the summer breeding season, monarchs live for only 2-6 weeks. But the monarchs that migrate to Mexico in the fall are different: They are born in late summer, stay alive all winter, and then migrate north in the spring.
