Northern Pearly Eye, Eyed Brown, AND aPPALACHIAN bROWN
Northern Pearly Eye basking with its wings open. This species usually rests with its wings closed, so it can be difficult to get a photo with the wings open like this. Northern Pearly Eyes fly from late May through August, and they are larger than our two species of Eyed Browns.

Ventral view of an Eyed Brown. This species is extremely similar to the Appalachian Brown (below). However, Eyed Browns have a more jagged post-median line on the bottom hindwing.
Ventral view of an Appalachian Brown. The post-median line is smoother than in the Eyed Brown (above). These are both localized and uncommon wetland species.
Eyed Brown with its wings open. I regularly find this species at Siebenthaler Fen in Beavercreek, from late May through early September. Eyed Browns prefer open and sunny habitat, while Appalachian Browns prefer shaded wetlands.

Northern Pearly Eyes are widespread but somewhat uncommon. I have found them in many different locations but never in any great numbers. I have one sighting at Cox Arboretum in all the years I've been hunting butterflies there. I also find Northern Pearly Eyes in small numbers at several other locations, including Siebenthaler Fen, Sugarcreek Reserve, Cedar Bog, Germantown MetroPark, Beavercreek Wildlife Area, Narrows Reserve, and the Creekside Reserve in Beavercreek.
