This struck me as a good place to try for the ever advancing Small Red-eyed Damselfly. Unless anyone knows different I don't think they have been found in the Peterborough area before. They were in the dyke next to The Boathouse pub, Longthorpe just beyond the small bridge over the dyke. There were plenty including many pairs ovipositing along with Large Red-eyed, Blue-tailed and Common Blue Damsels, a few Emperors and a Brown Hawker or two. Good nectar sources were attracting good numbers of Silver Ys and Painted Ladies.
Steve "Toadsnatcher" Dudley headed there soon after and got some better pictures which you can see here.
