Do they move them or not?
I have seen the argument a few times but never saw that a conclusion was reached that bees will relocate larva to queen cells in the hive. I personally can't say that they do or don't. What I do know is that while grafting one day, I lifted a larva from a cell while grafting at the hive and hesitated slightly as I cleared the cell for a bee passing by. She noticed the larva on my tool and wasted no time plucking from my tool and placing it back in the cell. I did peck her on the head for being a pain in my tail by the way.
What say ye wise and knowing beeks.............
