GFNC Observations: Butterfly

Tailed Emperor
Sign Post, 13th Beach
Seen flying W along the top of the dune in moderate NW wind, cloudy with sunny breaks, cool-sl warm. Seen briefly but large size, fast direct flight with some jinking, relatively pointed forewing showed it something different. Large white flash on the underwing and blunt tails (only on per hind wing was noted) seen in poor light then mainly whitish upper wings with black edging seen in good light.
