Common Emerald Damselfly Males
Another species new to me, Lestes sponsa. It prefers permanent lakes and ponds, which I have not visited much. These were at the Decoy Heath reserve.
It is also known as the Common Spreadwing. The Spreadwings are a group of damselflies which, when at rest, spread their wings more like dragonflies than the typical vertically folded over the abdomen position.
The dorsal side of the thorax is supposed to be metallic green (3rd to 5th images) but some of these seem to be one side gold or both sides gold. I don't know if this is due to reflections of the sunlight. I have seen no mention of this in descriptions of the species. Perhaps it is a sign of immaturity?
I saw no females.
