A scientific paper, Status of Danaus plexippus in Arizona, that reports the findings of the first ten years of the Southwest Monarch Study has been published in the Journal of the Lepidopterists' Society. You can download it here.

Top Ten Findings of Status of Danaus plexippus in Arizona.pdf
The Southwest Monarch Study is researching the migration and breeding patterns of monarch butterflies in Arizona and the SouthWestern United States. It was once believed that monarch butterflies East of the Rocky Mountains flew to the mountains near Mexico City for the winter and monarchs West of the Rockies flew to the coast of California. Through Fall tagging in the Southwest (Arizona, Nevada, New Mexico, California deserts, Utah and Western Colorado), we have learned that this is not always the case.
There is much more to learn about the wild monarch migration throughout the Southwestern states. If you love monarch butterflies, consider joining our study.

What Have We Learned So Far?
Over 400 Citizen Scientists have tagged monarchs for the Southwest Monarch Study. Since 2004, they have tagged thousands of monarch butterflies throughout the Southwest. Through recoveries, we now know that some of these monarchs flew to Mexico, and others to the coast of California (a recovery is a tagged monarch reported in a distant location) We have discovered monarch breeding habitats around the state and are also learning about monarchs that spend the winter in Arizona.
Through analysis of tagging and recovery data, we are also uncovering some fascinating patterns about weather, especially wind, and how it affects the monarch migration.
If a monarch you tagged is sighted in another location we will always contact you.
Look at our sample map. The dark lines represent recoveries
in the 2016-2017 season. The light lines represent earlier recoveries.
