Monarch Butterfly Migration
— Wildlife Migration —
The following spring they mate, the males die, and the females journey back to North America, laying eggs on the milkweed plants as they go. They may travel as far north as the Gulf coast states before they too die. The next generation continues the northward migration until once again, the monarchs repopulate the entire region of the milkweed plant.
Four to five generations may live and reproduce throughout the summer. However, the last generation, along with all the other monarchs from eastern North America, seek refuge from the cold of winter and begin the migration cycle once again.
