Club-Tailed Dragonfly

I saw this dragonfly in the garden this morning. I looked it up in my book and it is a Club-Tailed Dragonfly It says in the book 'Very local, being restricted today in stretches of Rivers Severn and Thames and a few sites in Sussex.' I don't know how it could have got up here.
Another very warm day. I got my hair cut this morning and I felt quite tired this afternoon so only did a bit of weed spraying but suddenly I felt quite dizzy and unsteady. Hope I feel better tomorrow although I am seeing the doctor anyway tomorrow.
