There were a few more Drone Flies on the Access Trail this evening and I think this rather more brightly coloured one was Eristalis arbostorum. Particularly the face appeared fairly well dusted white over the front surface, with only a slightly darker central smudge. The hind metatarsi were swollen to the width of the hind tibia, which were yellow at the base, dark at the apex, as also were the mid-tibia.
The thorax wasn't too furry, and the sides of the thorax below the wings were pale rather than black. I couldn't see the stigma on the wing clearly, but it seemed to be relatively small and unextended.
At the first Sallow on the outward path to Victoria Lane I found Anthophora longipes (several males and a likely female) on the Ground Ivy, Glechoma hederacea on the ground of the rabbit burrows, and many probable Bombus terrestris on the sallow catkins, together with its cuckoo parasite, Bombus vestalis, confirmed (probably) on ispot.
