Lestes sponsa (Common Spreadwing/Emerald Damselfly)

We have a population of these at our local Sandhouse Lane Nature Reserve. After the pond drying out for a large chunk of 2011/2012, my fingers were firmly crossed for continued generations but re-population seems to have happened successfully.

[I have a comparison chart showing the distinguishing features of our four emerald damselfly/spreadwing species.]
