Supercedure

If left to their own devices bees can and will make some dreadful decisions, as one of my best colonies has demonstrated by trying to supercede in the second week of September.  Supercedure cells differ from swarm cells in number and placing.  Generally supercedure has only one, sometimes two queencells, and they will be in the middle of a frame.  Swarm cells are usually built in numbers around the edges of a frame.  I have to use generalities because with bees there are always exceptions to the rule.
This one though is a textbook supercede, a single queen cell in the centre of a frame. A month ago I would probably have allowed this to carry through to its natural conclusion, which can mean two Queens occupying and laying in the same brood box, the old queen and her daughter.  This is not as rare as you might think.
But this late in the year and with the weather about to go downhill it is unlikely that a new Queen would be successfully mated.

For whatever reason the colony knows, or thinks their Queen is failing, which is why they are trying to replace her.  So before the colony decides to do something even more drastic I stepped in to manage the situation and remove the resident Queen.
Its for occasions like this that I keep mated Queens banked away in mini nucs.  This is my last spare Queen of the year, so fingers crossed that there are no more mishaps.
In a large busy colony like this one I like to introduce Queens using this type of cage. The cage with the new Queen inside is placed over a patch of emerging brood.  As the young bees hatch they automatically take the new Queen as their own and after a week or so the Queen can be released into the colony.
I have had a 100% success rate with this type of introduction..........so far.
