Great photo of the female dragonfly. Like the composition and sharpness.
To me this does not look like Sympetrum striolatum. The legs look like they are all black, lacking the brigter lines along the backside of the legs. I admit that these lines may be hard to see from this angle when present.
S. striolatum and S. vulgatum has these brighter lines along the legs, both on the thighs (femur) and shin (tibia).
S. striolatum has dark areas in front of the eyes, that does not extend down along the frontal edge of the eyes. S. vulgatum has same kind of black area, but it extends down in front of the eyes.
It is seen on the photo how the black in front of the eyes continue down as a fine line in front of the eyes. But other Sympetrum species has a similar appearence regarding this black area, e.g. Sympetrum sanguineum.
Sympetrum sanguineum has all black legs with no brighter lines. Further more the two dark markings at the end of the abdomen (tail), is typical seen on S. sanguineum. So I think it's a female Sympetrum sanguineum you photographed. In the picture I can see it's a female, because the two appendages at the end of the abdomen, is spread out some distance from each other.
cheers
