Enallagma annexum
Northern Bluet is a common and widespread bluet across much of North America. Its range was once thought to include northern Eurasia, but recent genetic studies (Turgeon et al. 2005) showed that Eurasian and North American populations separated about 250,000 years ago and should now be considered separate species. The Eurasian Bluet goes by the name Enallagma cyathigerum — which was the name given to the combined group (e.g., Manolis 2003) — but now that they are split, the North American bluet is Enallagma annexum. The photo below illustrates that an abdomen can be very flexible (all bluets can do contortions).

I saw your comment this morning, Emma ... it's gone now. I'll say this: Odonates need love too! ;-) Speaking of love, this is -- as you no doubt know -- a mating pair of damselflies. They are "in wheel," sometimes referred to as "in heart" when damselflies are mating. Nice photos -- damselflies are so small that DSLR cameras/lenses won't autofocus sometimes!
thanks next to gone.
Great series!
Not a bad idea! are you a jewelry designer?I find the heart shape quite fascinating too. Remarkably flexible bodies!
This lake is swarming with Dragonflies right now. Especially these bluets.
After a month each and every dragon fly will disappear and the lake will be totally empty of them. this is when the Cormorants and Herons come in.
They were just like a heart shape, awesome ! May I design a series of jewelry for them?
