I was fairly excited to find this dragonfly a week ago a week ago in Ipswich, Massachusetts. The best guess that I have is that it is a female Ashy Clubtail. The second choice would be a Dusky Clubtail, my books tell me that it is best determined “in the hand”.
This female has been through a great deal. Her wings are missing bits and pieces.
This dragonfly was about 100 yards away from the Ipswich river.
Just for fun, here is a female Blue Dasher.
