Lower Valley

Had a walk from Darren Woods to the sewage works in the first fine day for what seems an age. Garden Warblers were singing in the woods as were many Song Thrush. A Reed Warbler was singing from the sewage works reed-bed but the undergrowth was too much for me to get a better look. Otherwise all the usual summer and resident birds were in full voice.

25 species of hoverfly were seen, with quite a few first for the year and some bright colourful species highlighted by a male Criorhina berberina which was a first for me, but not the valley. Other insect highlight included Ashy-mining Bee and the Large Red and Black Froghopper.

First blooms of the year included Herb Benett, Dovesfoot Cranesbill, Wood Cranesbill, Pignut, Holly, Common Chickweed, Black Medick and Dog's Mercury.
