Journey North is a wonderful website that
tracks the North American Monarch Butterfly Migration, each year, with the complete involvement of the general pubic.
Every fall, a magical event takes place—the annual monarch migration to Mexico. If you live in Northen America they may be traveling over your own head right now—or clustered by the hundreds in a nearby tree—monarchs are on the move.
- How do the monarchs know when to go to Mexico?
- How do they know which way to fly?
- How fast, how far, and how high do they travel?
Report Your Sightings and Track Migration
What they're asking people in USA, Canada and Mexico to do, is report any Monarch Butterfly sightings.
Here's how it's done.
There an App for your phone, to report sightings.
Monarchs produce four generations during the typical breeding season and the population grows with each new generation. Monarch numbers reach their peak by fall migration. At no other time of year is the population larger.
The generation that's developing now will be the great-great-grandchildren of the monarchs that left Mexico last spring. These butterflies have a long and challenging life ahead: they will migrate to Mexico this fall, survive the winter, and return in spring 2016 to begin the breeding season anew.
