So, you have a damselfly that isn’t a Demoiselle.
Now we can home in further knowing how extensive the pterostigmas are, wide and quite regular spanning 2 or more cells or narrower spanning 1-1½ cells.
Most of our damselflies sit with their 4 wings folded together, making seeing the underlying cells very tricky so concentrate on the overall shape:
wide rectangle – Emerald (Lestes)
narrower lozenge – non-Emerald (Lestes)
If the pterostisgmas really aren’t clear, the wider pterostigmas are for our 4 Emerald Damselflies and it is mostly safe to risk colour at this point, all the emeralds showing dorsal sides that are a variation on metallic green, including bronze-green variations.
Dorsally metallic green/bronze-green abdomen & thorax
NOT metallic green/bronze-green
