Libellula quadrimaculata - the Four-spotted Chaser - what a corking dragonfly! This one had just emerged out of a pond on Strensall Common and looked glorious warming up in the morning sunshine. I also saw my first Emperor Dragonfly - a male- recently emerged too, shining cobalt blue and bright green. Also seen, a pair of Spotted Flycatchers in a different place, but presumably the same pair as I saw a fortnight ago and a nest of very rowdy young Great Spotted Woodpeckers on the YWT reserve. And the sheep were all happy chilling in the shade!
