Coordinator notes: As described in Glassberg's " A Swift Guide to Butterflies of North America", by range, this should probably be C. cecrops. However, by the characteristics of this sighting, it looks closer to C. isobeon, which is where I am placing it. The sighting locale is close to the fringe area of the two described species, and apparently there is some thought they may actually be one species. SAT
