The reddest of them all
This scarlet darter (Crocothemis erythraea), vuurlibel in Dutch, landed next to me as I was sitting near a pool.
It is relatively easy to recognise, because it is red all over: body, eyes, nose, and legs.

The female and young males have a different colour, look at this post for a fine photo of one that @davidgermano just posted.
