Migration Moves into Arizona

Temperatures are heating up in California and Arizona and this week monarchs are expanding their range into the middle elevations of Arizona for the first time this Spring! Monarchs are still being reported along coastal California and the lower deserts of Arizona while milkweed is beginning to emerge in the northern regions of the West.

For the Eastern population of monarchs, it is still a story of overlapping generations and egg loading. For the Western population of monarchs, migration moves into Arizona. Exploring Together focuses on population growth.
