The first is a Marsh Bluet - probably - since according to Lam's "Damselflies of the Northeast," this species is nearly identical to 3 other species and can only be reliably identified by examining the shape of male 's cerci - and that requires netting it, then using a magnifying glass.
|Marsh Bluet (? probable or ? possible)|
The next 2 can be identified in the field with binoculars or a camera and I am reasonably certain on the IDs: Northern Bluet and Aurora Damsel:
Hope you can get outside and enjoy the wonders of the season.
