How long does it take the monarch butterfly to fly from Mexico to Canada?

The monarch butterfly typically takes about 2 to 3 months to migrate from Mexico to Canada. This journey, which can span over 3,000 miles, occurs in stages as the butterflies travel north, often stopping to feed and reproduce along the way. The timing of their migration can vary based on environmental conditions and the specific routes taken.
