A hot, sunny day, +28° C. Been to Epsom.
Most of the insects were seen near the Great Stew Pond.
Plenty of Anasimyia lineata there, never seen it before! Only attended Ragwort flowers:
Lots of Brimstones (Gonepteryx rhamni), fuelling up for hibernation. These only attended thistles:
I have a feeling this is a syrphid, but having sifted through two hoverfly books I still can’t name it!
Upd: It is a Oplodontha viridula soldier-fly (ID by Ian Andrews):
This bumblebee mimic is probably Eristalis intricarius, but the light-coloured scutellum confuses me…
Upd: ID confirmed by Ian Andrews
Eristalis nemorum in courtship, with male hovering above the female:
This, I guess, is a male Lasioglossum calceatum bee:
This could be a male Nomada flavopicta cuckoo bee (the first three abdominal segments have pairs of widely separated yellow spots):
Plenty of Leaf-cutter bees (Megachile sp.). The abdominal pollen-brush is orange in colour, but after visiting thistles it is all white from pollen:
Comma (Nymphalis c-album):
Dioctria baumhaueri robber-fly with prey:
Harmandiola tremulae cecidomyiid fly galls on Aspen:
Lots of Helophilus pendulus on Ragwort:
