Common Buckeye
Junonia coenia
A sun-loving brown butterfly marked by bold orange bands and large colorful eyespots.
Common Buckeyes favor open sunny ground, roadsides, dunes, gardens, and disturbed fields. They often bask with wings spread and fly low in a fast, erratic path when approached.
Adults visit many nectar flowers. Caterpillars use plantain, false foxglove, snapdragon relatives, and native wild petunias as host plants.
