I thought this image might just be useful in illustrating morphological differences between hoverflies and bees.
No interactions present.
The hoverfly cannot be taken to species, but it is a Syrphus. To be sure of ribesii, you would need a clear idea of hind femora colour, hairiness of eyes...etc.
My Flickr photos...
The difference between the one pair of wings (flies) and two pairs of wings (bees) can be hard to see in photos and in live specimens, but the bee's much longer antennae is shown well in this intriguing photo.

The first picture on the carousel, for Syrphus, is surely not a Syrphus...
The second picture on the carousel, for Syrphus, is surely not a Syrphus...
Or is it just me?!!
I agree ophrys, and have added my agreements to the observations in question, which means that they're no longer in the carousel of photos above, so your comment and my reply may be mystifying to anyone seeing them now!
The observations we were looking at are:
Nice to tidy things up!
