Caught this dragonfly on camera as it visited my flat this morning. I'm in London by the River Lea, very near Leyton Marshes.
The wings in sunlight almost glistened like gold! Picture is taken as it sunned itself and so the head and strip colour is hidden a bit by the glare, but it was a pale green. I'd estimate that it's about 7cm long from head to the bottom of the of its body.
