Just for a change, I took a stroll around the 'long loop' at Upton Fen NNT reserve. The sunny weather had brought out dozens of butterflies, including half a dozen Wall Browns - nice! A Hornet was busily paper-making on an old stump!
Lots of dragons, too - literally scores of Brown Hawkers and hundreds of Migrants: I managed to photograph a Brown just post-emergence. Lots of really bright Emerald Damsels, too: I wonder how long it'll be before Willow Emeralds arrive....
A well-marked Buzzard flew over the reeds, stimulating a hidden pair of Cranes to start trumpeting. As I attempted to photograph the two adults I could see with binoculars, I'm almost certain I caught a glimpse of a brownish juvenile peering over the reeds.
I think the white flower is 'Grass of Parnassus'!
