Perhaps Chris Brooks can help with this ID. I was at Wicken Fen yesterday. Hottest day of the year and the dragonflies were out in force.
No interactions present.
It must be right at the end of its season. The hairy thorax is quite clear, the abdominal markings and shape of the anal claspers all suggest a male Hairy Dragonfly.
