However the only dragonfly on show were Emperors
This female was wing beating so hard it created ripples radiating outward
After watching one male hawking up and down the edge of the reeds for about fifteen minutes it suddenly dived through a gap in the reeds and I guessed settled somewhere in that area. So I did my Ray Mears bit and circled around it so that I was between the sun and the presumed basking dragonfly. I edged forward to where I guessed it would be perched, scanning every possible spot. After ten minutes of inching forward I thought, enough, I'm off for tea. Took one step forward only to have both male and female rise a yard in front of me and hover a foot in front of my nose before heading off over the pond.
Still there's always next time.
