The Monarch Butterfly (
Danaus plexippus) is one of the most abundant and widely recognized species in the world, and they are the only butterfly known to make a two-way migration. Like birds, their movement is driven by seasonal changes, so day length and temperature changes influence their trip.
Each fall, monarchs from the eastern U.S. and southern Canada undertake a much longer journey, up to 3,000 miles, to wintering grounds in the mountains of central Mexico.
