Damselflies in Tandem

There has been quite a lot of damselfly activity in and around our garden pond. In both of these photos the damselflies are in tandem. The first photo shows the damselflies copulating. In the second photo the female is depositing the fertilized eggs into a clump of oxygenating plants. The female here is the green form which is more common than the blue form of female damselfly. I haven't managed to capture the 'wheel stage' of mating yet.

I think that these are the common blue damselflies, Enallagma cyathigerum, but they could be azure damselflies, Coenagrion puella. I need someone with a bigger screen and more knowledge to correctly identify this pair.
