Appalachian Azure was described as a separate species by Harry Pavulaan and David Wright in 2000 (International Lepidoptera Survey, 2000). It occurs most commonly in the Mountains and Ridge and Valley, but it also occurs in counties of the northwestern Piedmont south to Coweta County. The hostplant is black cohosh (Cimicifuga racemosa), which grows in rich, moist soils in mixed deciduous woods in north-facing mountain coves, on ridgetops and along stream margins. It is univoltine with the flight beginning in most years in mid-May and lasting into early July, but in some years beginning in late April farther south (Bartow, Fulton, Coweta). The flight begins as the univoltine flight of C. ladon in ending and ends as the first flight of C. neglecta is beginning, but the overlap is negligible (Pavulaan and Wright). Females tend to stay near the hostplants but males stray, especially at the beginning of the flight period (Pavulaan and Wright). Early Date: May 4; Late Date: July 8. Conservation Status: Secure.
