| DISTRIBUTION in North Carolina: Statewide, undoubtedly occurring in all counties, but primarily a northbound migrant into the state in summer and fall. Small numbers of adults appear in spring from larvae that have successfully overwintered. |
| ABUNDANCE in North Carolina: Except after harsh winters, it is abundant in late summer and fall in the Coastal Plain, especially in the lower Coastal Plain. Numbers decrease inland, but generally fairly common to common in the eastern Piedmont, and uncommon to fairly common in the upper Piedmont and mountains. Numbers are typically highest in September, when over 100 individuals can be seen in a day in some Coastal Plain counties. Mostly uncommon to occasionally fairly common in spring and early summer. |
| FLIGHT PERIOD in North Carolina: One relatively small brood from early March through June. However, one to two additional broods from July to late fall. The bulk of the butterflies are present from mid-July into November, peaking in August and September. Most of these are clearly migrants; there is an obvious north or northeast movement in August and early September. |
