Azure but not blue

I still find identifying damselflies quite tricky especially when they are in their teneral form and lack the final colouration. At first glance I thought this might be a White-legged damselfly but I'm reasonably confident - based on the Coenagrion spur on the thorax - that its actually an Azure damselfly in its teneral form. Either way, what I really liked was the arrangement of reeds in the background.
