30 species of hoverfly registered today. With Leucozona glaucia making it 99 for the 1km square and Helophilus hybridus making it 100 for the valley this year once again (7th year on the trot). Other highlights were Chrysotoxum arcuatum, Chrysotoxum festivum, Xanthogramma pedissequum, Riponnensia splendens, Eristalis intricaria, Sericomyis silentis and Volucella pellucens. Most numerous species was Eristalis tenax (80).
A latish Broad-bodied Chaser was unexpected otherwise only highlight was the finding of the plant Alsike Clover a first for me although it does seem to be on the valley list.
