Common Blue Damselfly

Common blue damselfly, Enallagma cyathigerum. Male. Hayes Street Farm, 19 May 2011.

I posted a photo of one of these beauties as part of the report on reptiles in Keston, but this one has such a well-placed shadow that it's worth adding another. Below are a male and female in tandem; they were flying together like this.

(Later addition: An expert has since informed me that the pair below are azure damselflies, Coenagrion puella, so I have re-labelled the photo accordingly.)

Azure damselfly, Coenagrion puella. Pair in tandem, male above.
