Every August, monarch butterflies east of the Rocky Mountains begin their migration from southern Canada and the northern United States to central Mexico to hibernate. In the spring, when temperatures warm, they awaken, mate and begin their migration north again to lay their eggs. In Texas, scientists with the National Wildlife Federation are now tracking monarchs during their migration to understand where they roost and protect the habitats they rely on.
