Distribution and Habitat
Buckeyes prefer open, sunny locations in fields and clearings. They are nervous, and alert, and fly quickly when nearby movement is detected.
It cannot live in freezing temperatures, but moves quickly northward in the spring to most of the United States and south Canada. The population swells in the fall during the southward migration.
