>If a queen is failing. Does she know this,and still lays an egg in a queen cell? wouldn't this be like suicide. Or do the workers take an egg form another cell,and put it in the queen cell. I don't know just trying to think like a bee.
Queens lay eggs. They don't "think" in terms of being usurped. They "think" in terms of "I need to lay some drones" or "this looks like a good clean cell".
>No.. if they are going to superceded her, they convert the cell to a queen cell.. lavish royal jelly on the larvae, and make a queen
Sometimes. But sometimes they make cups and the queen lays in them. I've wathced them extensively in the observation hive and have seen them do it.
