About Gray Buckeye
Junonia grisea, the gray buckeye or grey buckeye, is a species in the butterfly family Nymphalidae. It is found in North America, west of the Rocky Mountains. Like the common buckeye, the gray buckeye is a brown butterfly with eyespots on its wings that distract predators from its body.From Wikipedia via iNaturalist — article, CC BY-SA.
