Queen Bees have long life span compared to other Bees within the colony, living sometimes for up to 4-5 years, however they will eventually die. When this occurs, or usually as an older Queen being to fail, the Workers can rear a replacement Queen from previously laid worker larvae. This replacement of the old Queen will happen without Swarming and is known as Supersedure. This usually happens later in the year than Swarming, around early September (but again is weather dependant).
