This Hobby put on a delightful display hawking dragonflies with the Emporer seemingly the favourite. I managed to catch a brief burst of shots where it clearly shows one of the plucked dragonfly's wings falling to ground (below).
The image below shows the dragonfly looking more like a fish than insect.
Flying past the hide at Walmsley; this was the only decent, in focus close shot I managed.
EXIF Detail: Aperture F5.6. Shutter 1/1250s. ISO 250. Exposure 0.0 EV. Focal length 500mm. Hand held from hide.
