Enallagma anna. The bluet could be a marsh bluet Enallagma ebri= um=2C but in my picture the second segment looks pointed and the size of th= e black segments seems to increase as you go further back. In the picture = that I have of the marsh bluet the size increase of the black segments does= not seem to conform to what I would expect in the photo that I have. Also= the cerci appears large in my photo in comparison to what I would expect i= n another bluet. The picture is not of hight quality=2C but it should be g= ood enough to determine species as it can be narrowed down to three possibi= lities that I can see. I've ruled out familiar bluet due to the size incre= ase in the black segments as you move back. So that leave two possibilitie= s if I did not miss something. I'm doing my comparison bassed upon Damself= lies of the Northeast and the Beginner's Guide To Dragonflies. My spreadwi= ng by the way I've determined is an emerald spreadwing.
