Goal: How do you identify a queen bee by activity level?
Once you have smoked the hive and opened it, observe the bees’ activities. The workers and drones will be moving about and working on the hive. The queen’s only duty is to lay eggs. She is fed by the rest of the hive. Therefore, the queen be can be identified by finding the bee that isn’t usually doing much of anything.
Observe hive for prolonged periods to identify queen by her constant, active movement and larger size.
