It doesn't always happen. There is a form with completely transparent wings - in females more often than in males. In general, in the middle zone, the choice is small - there are three yellow-legged species: S. flaveolum, S. vulgatum, and S. striolatum. In the vulgatum, the black pattern on the body is not so strongly developed, and there are usually light forearm stripes on the anterior-upper surface of the chest. Striolatum has an extremely short black stripe in front of the eyes, and the forehead is almost entirely light. Well, the genital plates - although the tail is not in focus here, and in these two species, most likely, a protruding plate would be visible. Here at flaveolum it is quite short and adjacent.

Yes, I now think that 13 is also a female flaveolum. It even seems to show yellow spots on the wings in the area of the nodule.

The guard!!! How to distinguish these arrows from photos?!
Coenagrion puella, Enallagma cyathigerum, Coenargion hastulatum.
In appearance, in my opinion, all the same! Or are there clear differences

Of course, there is. Males of the first two differ very well: see here males of Coenargion hastulatum are more similar to enallagmas, in the hands they differ in the shape of the caudal appendages and the shape of the pronotum, in the pictures the most noticeable difference is that the enallagmas (both males and females) have a noticeably wider light forearm band on the chest. You can see this in the same image from the link.
Female arrows in the photo generally differ poorly. You need to look at the shape of the pronotum and the pattern of the abdomen, but you may not be sure.
