A few days ago, I saw the bees clustered around the hive entrances after a hot day and got really nervous that they were getting ready to swarm. Until then, the bees would head inside once the sun started going down. On this particular night by 8:30pm they were still in a bunch outside, and the numbers were growing. I thought for sure they’d be gone by morning having swarmed in a tree out of my reach. It didn’t happen. The next day they huddled again, and then they did the same thing again on another warm day. Turns out, this is how they cool off. They were also hanging out by the container pond I set up for them as a water source. Lesson: bees have chill.
