Fueling the fall migration of the monarch butterfly [PDF]
Integrative and Comparative Biology, 2006 Monarch butterflies in eastern North America accumulate lipids during their fall migration to central Mexico, and use them as their energy source during a 5 month overwintering period. When and where along their migratory journey the butterflies accumulate these lipids has implications for the importance of fall nectar sources in North America.
