Not very often in June to you get a day like this for hoverflies with 37 species seen [in fact my best day count ever]. The area was a sunny glade in the woods that are on the right hand side of sewage works lane near the bridge. I could see the area from the lane, but had to wade my way through the quickly growing Japanese Knotweed to get there. This area must have been hoverfly central, with over 300+ Umbelifier plants in flower [Upright Hedge Parsley & Hemlock Water Droplet]] and also a small stream running through it and ample secondary growth and also flowering Garlic Mustard, Germander Speedwell, Red Campion and Herb Robert. Below are photos of some of the species. The only downer was the Parhelophilus species that got away [would have been a valley first if ID'd] .
All difficult species have been verified by the Hoverfly Recording Scheme.
