Not scientific, just for fun.

How can they do get this?? Is it video manipulation? A very good manipulation. I saw with more care, and I think they use some kind of string. DO you agree?

I haven't worked out how they get the tabanids to roll over (though I have a few ideas), but once on its back, there are a couple of ways to keep it there [a dab of quick-set glue, or a sticky tab]. Once it's stuck on its back, the ball-rolling is straightforward. All insects will hold a ball and walk "on" it (thus turning the ball round and round).
No, it's getting them to roll over that's the tricky bit ... I think it may be to do with magnets...
Please keep this thread going until we find the answer - I don't want to lie awake every night trying to work out how it's done!

I photographed a tabanid doing the sam (laynig on its back), so it has got inclination to do that; but how to put this "spell" on it???
