The population of Argynnis atlantis of the central Appalachian Mountains, primarily on the Allegheny Plateau of West Virginia, has long been recognized by entomologists in the eastern United States as distinct from nominotypical populations of A. atlantis in the northeastern United States and eastern Canada. Larger size is often cited, but actual comparison of wing markings has not been done to date. This study applies RGB color analysis on a series of adults from both regions and looks at potential differences in wing markings which may distinguish them.
