Last week I spent some time out in Beelandia examining both Metpropolis and Bee Glad... . The temperature was in the 40s, so I watched as bees took cleansing flights, carried out dead bees, and a few just fell to the ground to die. The bees are still alive and looking fairly well, though the few dozen or so bees (mostly drones) around Metpropolis freaked me out a bit.
Within 24 hours, the temperature fell 40 or so degrees with a wind chill that made it feel like -40 degrees. I suspect the bees are inside clustering to keep warm.
