Each fall the monarch butterfly travels thousands of miles to spend the winter in the forests on 12 mountaintops in central Mexico. The monarch migration is the most spectacular two-way migration carried out by an insect.

The forests provide unique microclimatic conditions that allow monarchs to survive the winter. Forest degradation is putting this amazing migration in peril.

In the Spotlight

Board Member Gail Morris, along with Christopher Kline and Scott Morris published their first paper, "Status of Danaus plexippus in Arizona"  in the Journal of the Lepidopterists' Society. It contains the limited history of monarch butterflies in Arizona as well as a compilation of the authors' findings. It was reviewed by Dr. Robert Pyle and Dr. Lincoln Brower prior to publication. The authors also put together a great list of Top Ten Key Findings. Congratulations on a job well done!
