Hoverfly seen on pyracantha blossom. Initial secondary image was different insect. Added the correct second image now. Apologies.
No interactions present.
Abdominal markings not matching thumbnail, head profile resembles that of a female Platycheirus clypeatus, ( Hoverflies F.S. Gilbert ), but again abdominal markings do not correspond. Good sharp photos by the way.
Thanks, looking at the other thumbnail, you're quite correct about the abdominal markings
As ophryus has correctly observed I initially had two separate hoverflies shown. I've now removed the impostor and given an additional view of the syrphus above. Many apologies for the mistake.
