Large Red Damselfly (Pyrrhosoma nymphula).
Several of the Odonata species were on the wing along a small mountain stream in the Sierra de Almijara. I only managed to photograph males but several insects were seen in tandem. This was the only Dragonfly species seen at the site which was surprising as the site looked ideal.
