It seems to me that this Damselfly owns all the characteristics of Erythromma lindenii. I have shot this picture rather far from water though I have read that these Damselflies rarely come to the shore. The lengthy and pale pterostigmas are not very visible on this picture. |

Here is one immature male observed on the bank of the Doubs river. It does not show its final colours. |
