Damselflies

Calopterygidae (Broad-winged Damsels)

Calopteryx maculataCalopteryx maculata (Ebony Jewelwing), male female (Parker Meadow, 6/28/07 11am, Lower Vine Brook, 6/19/11 2pm, Willard's Woods, 7/10/05 4pm, Lower Vine Brook, 6/22/13 11am, 7/7/13 3pm, 7/10/2021 3pm) I was able to catch the female in the last photo because it had a broken wing, and then I found a broken-winged male in roughly the same spot 2 weeks later.

Calopteryx amata (Superb Jewelwing)

Calopteryx aequabilis (River Jewelwing)

Calopteryx dimidiata (Sparkling Jewelwing)

Hetaerina americana (American Rubyspot)

Lestidae (Spreadwings)

Lestes forcipatus (Sweetflag Spreadwing)

male Lestes congenerLestes congenerfemale Lestes congener (Spotted Spreadwing) (Willard's Woods, 10/1/05 12pm) Both this one and the spreadwing above are Lestes, but I'm not sure if the species are correct. I am somewhat more confident in the indentification of the female. They are hard to identify without capturing them.

Lestes unguiculatus (Lyre-tipped Spreadwing)

Lestes dryas (Emerald Spreadwing)

Lestes vigilax (Swamp Spreadwing)

Lestes inaequalis (Elegant Spreadwing)

Lestes eurinus (Amber-winged spreadwing) male (Parker Meadow, 8/4/07 5pm, 7/29/07 1pm) I am not 100% sure of this identification because I can't see any amber in the wings, but it seems the best match based on the rest of the identification criteria.
