Do owls eat honey bees

I was wondering the same thing the other day when I saw about 20 of each in what appeared to be a "swarm". They flew around together in circles and I thought that the swallows were trying to eat the dragonflies but they weren't. I've never seen anything like it in my life. My son and I watched them for about 1/2 an hour while we were on a bike ride. We had to get home and they were still circling as we left. The dragonflies were very large too so I would have heard a crunching if they were being eaten.
