Common Buckeye Butterfly

Named for its conspicuous target-shaped eyespots, the common buckeye, Junonia coenia Hübner, is one of the most distinctive and readily-identifiable North American butterflies. It inhabits a wide variety of open, sunny landscapes including old fields, roadsides, utility corridors, gardens, parks, yards, fallow agricultural land, scrubs, pine savannas, and weedlots.
