News: Here Comes the Migratory Generation
The first members of the migratory generation will emerge in the north by mid-month. These butterflies are the great-great-grandchildren of the monarchs that left Mexico last spring. They have a long and challenging life ahead: they will migrate to Mexico this fall, survive the winter, and return in spring 2017 to begin the breeding season anew.

Monarch numbers reach their peak by fall migration. At no other time of year is the population larger. Monarchs produce four generations during the typical breeding season and the population grows with each new generation.
