The picture is of a female Great Pondhawk, confirmed on the BugGuide site. Rod
Corrected - earlier posting of it being a male was in error. Rod
Edited - generally speaking, very difficult telling the male vs female. Eye coloration and shape of the cerci, with the latter being the best. As all dragonflies tend to have males and females in the same area, I watched for a week or more before getting a confirmed shot of a male.
Will not clutter the database with a picture. Rod
