Looks like a hoverfly, but if so I can't get the species. Lots of light brown, almost golden fur. This specimen has a deformed wing.
No interactions present.
You can rule out Eristalis quickly because the wing lacks the looped vein characteristic of that genus. Many Cheilosia are very difficult to take to species from a photo.

Thanks, I will bear that in mind.
