Only had a short time after a family get together, to go for a walk, so decided to walk Foel Fawr (well the part in the Caerau 1km square anyhow) not far from the house. The area is regenerating former forestry clear-fell, with lots of plants like Angelica, Hemp Agrimony and Common Fleabane having some good patches before the Himalayan Balsam will eventually take over. I hadn't recorded much on previous visits but today I recorded 26 species of hoverfly. Highlights being Chrysotoxum arcuatum, Eupeodes latifasciatus and Xanthogramma pedissequum. The commonest hoverfly was Eristalis pertinax (85).
Chrysotoxum arcuatum
Cheilosia bergenstammi
Eristalis horticola
Syrphus ribesii
Most of the old forestry paths have been left to nature, this is where the wild flowers tend to congregate
