This is another Common Checkered-Skipper. Note that there is a nearly identical species in the southern U.S. called the White Checkered-Skipper. These two species are virtually impossible to tell apart without dissection. But to my knowledge, White Checkered-Skippers have not yet been documented in Ohio.  

Checkered White butterfly. This species is rare in our part of Ohio. My only sightings are from September and October 2012, which was a good year for rare butterflies. Photographed at Cox Arboretum.

Common Checkered-Skipper. This species is typically a late summer and fall visitor to Ohio. However, there are some indications that it might be able to overwinter in southern Ohio if the weather is mild enough. I have a handful of sightings from April and May, but it is much more common to see this species in late summer and fall. They can linger quite late in the year. (My latest sighting is November 13th.)
