What are my bees doing? I came out Monday morning to find this:
Could this be the remnants of an overnight bee beard? It was super-duper hot the previous day (90F), still 82F when the bees retired, so maybe they had bearded? But it got down to 63F by madrugada – do bees un-beard in the dark?
Or were they doing something entirely novel to me? I looked closely at this line (it was a bigger pendulum when I first saw it), and it did not appear to contain anything but worker bees, so they weren’t kicking out drones, saving their queen, or removing an intruder (all hypothesis I considered).
