when do the monarch butterflies return to mexico
Monarch butterfly migration Starting in September and October, eastern and northeastern populations migrate from southern Canada and the United States to overwintering sites in central Mexico where they arrive around November. They start the return trip in March, arriving around July. No individual butterfly completes the entire round trip; female monarchs lay eggs for the next generation during the northward migration[2] and at least four generations are involved in the annual cycle.
