in dragonfly species of the genus Calopteryx, androchromism in females is quite common, i.e. females have the color of males (dark blue body with pigmented black wings), although most often females are smoky green with transparent wings, so you should first pay attention to the presence of secondary genitalia in males (which is inherent only in dragonflies), or for the presence of an ovipositor in females and only then determine up to the species by color. Of course, I would like to see a photo of a dragonfly!!!!!!!! If you have one, you can send it to odonata@mail.ru, I'll try to help. I wish you good luck!
P.S. The beautiful girl C. virgo this year I met in the reserve "Bryansk Forest", Nerussa river, there they are definitely there. They are very fond of clear cool water, highly shaded. Beauty shiny is not as sensitive to turbidity of water and to its contamination as a pretty girl, so it is much more common. Write to us and I'll be happy to respond.

according to the Hump's determinant (S. N. Gorb, 2000) - in females, C.virgo-smoky wings with brown veins. The pterostigma is small and narrow-1 mm, 5 mm distant from the wing apex
. C. splendens-the wings are smoky green with metallic green veins. The pterostigma is 2 mm or more, CONVEX, and 3 mm distant from the apex.

I am inclined to believe that this is C. splendens (judging by the pterostigma). Color (or rather, a shade of the same color) - it changes a lot both during the life of a dragonfly and when storing collections. The veins may change color during storage and appear brown, although they had a metallic green color when living in the LIGHT.
You can also add the following information: C. virgo-fans of very cool flowing reservoirs, TRANSPARENT, without suspensions in the water column. They live in heavily shaded areas (Popova, 1953). Analyze the location of your find. Very rarely caught in a net

C. splendens - can tolerate turbidity of water, heat, siltation, so they are more common in muddy reservoirs.
