Monarch butterfly migration map

This map displays the North American monarch butterfly range. There are two monarch butterfly populations in North America - eastern (east of the Rocky Mountains) and western (west of the Rocky Mountains). The eastern population overwinters in central Mexico and breeds throughout the United States and southern Canada. The western population overwinters along the California coast and breeds across the western states and southern Canada.
