Possible "Coenagrion" an "Sympetrum" Dragonflies, GER

Hi,
I´ve been diligent these days . The following pictures may show a "Coenagrion" and a "Sympetrum" species. But which one ???

Hi

I think that your Coenagrion is actually Erythromma lindenii. Was it close to a pond? I reckon that the Sympetrum is Sympetrum striolatum but I will freely admit that the Sympetrum family is all a bit confusing to me.

Edit: I know that I said that the spur on the thorax was typical of Coenagrion but lindenii is complicated and has changed name at least once. I am not convinced that it should go with Erythromma or Coenagrion and was perhaps best left on its own as Cercion!

Thanks,
I already thought of "Erythromma lindenii" (just under a other name). Well, it wasn´t actually near a pond, it was directly near the "Isar", a river in my area.
Well "Sympetrum" species aren´t very easy, indeed. Especially if they´re females.

The Isar seems like a nice wide and slow flowing river almost like a lake. lindenii is a lover of nice calm waters and I have only ever seen them on lakes and ponds but it seems they can live on slow rivers.

The fact that no one has said that it is not striolatum is a good start!!

I've only seen Blue-eye/Goblet-marked Damselfly/Erythromma lindenii on slow flowing rivers so far!

I agree with Erythromma lindenii & Sympetrum striolatum.

Unfortunately, the pattern on the side of the thorax seen here is typical of both Coenagrion and Erythromma. The upper 'spur' is useful for seperating Coenagrion and Enallgama, but doesn't help with the similarly coloured lindenii.
In many respects, including behaviour, lindenii is similar to the Red-eyes.
