If you look carefully, you can see the blurred motion of the bee's wings. I read online that the bee's wings are small for its body, but beat 200 times per second letting the bee fly or hover in one spot.
Until I read your explanation I thought maybe that was a spider web in the background. Fantastic! FAV and a Follow! (When I was a kid they used to tell us that scientifically bumble bees couldn't fly, they just didn't know it.)
