Buckeye Butterfly Coloration, Markings and Size

The Common Buckeye butterfly (Junonia coenia) is brown above. The forewing features two orange bars and two large black eyespots outlined in orange. The hindwing has two eyespots, with the upper one being the largest and containing a magenta crescent.

Typical size of the Buckeye is in the 2.0" - 2.8" range.

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.

Nectar and Host Plants Used by the Common Buckeye

The favorite host plants of the Buckeye include snapdragon, gerardia, false foxglove, monkey flowers, plantains, ruellia and others.

They can be found on a variety of nectar plants such as Zinnia, Butterfly Bush, Hydrangea, and others. Buckeyes also take fluids from mud and damp sand.
