Yesterday morning around 10am I looked out of my kitchen window and saw a lot of activity in front of the hive. Couple of minutes later there was even more activity and I ran outside. There were maybe 10 000 to 20 000 thousand bees flying over my neigbours lot in a circle. Some of them landed on trees but most of them were just flying around. I was already sure that I would lose half of my hive in that swarm but 30 minutes later they returned to the hive. After the bees had returned I saw some them on the landing board beating their wings like trying to cool down the hive. Couple of hours later we checked the hive: - hive is crowded but not overly so - queen was still there - found a supersedure cell - no swarm cells (there has been some previously) We decided to: - add a new super just in case - remove the queen cell Newbee here trying to understand what just happened. Could someone explain what just happened?
