Tenacious guard bees?
I seem to have noticed that there are a few guard bees out front that are intent on jumping on ANY incoming bee. They will perch up on their hind legs and use their front legs as Velcro. If any bee happens to land near her, she jumps on them and the rustle a bit, and then go back to their business. There hasn't appeared to be any stinging or deaths, but I've never quite witnessed this before. There have been a couple of times where TWO of the bees will hold down an incoming forager, seemingly smelling her, and then let her go about her work. I did happen to see a yellow jacket nearby hovering about, but I'm not sure if the girls are just being over protective of their home, or what?
