Before heading for Skipwith Common in the afternoon, my father and I dropped into Pocklington Canal at Bielby, to try to photograph Banded Demoiselle Calopteryx splendens. Their main habitat here is Bielby Beck which runs close by to the canal. Although there was little sun, several were seen and photographed. In addition there were several Azure Damselflies Coenagrion puella and Blue-tailed Damselflies Ischnura elegans, though no signs of any other species, the canal now being quite overgrown with emergent vegetation.
A few butterflies were also observed with Large Skipper Ochlodes venatus, Meadow Brown Maniola jurtina, Ringlet Aphantopus hyperantus and Speckled Wood Pararge aegeria all present in small numbers. A few other invertebrates were also photographed a seen below.
