I was out a few days ago to cover my hives with roofing felt. It was in the mid 50's and bees were out. Saw 1 bee not moving but still alive. His wings looked withered or maybe worn out. Did not see any other bees like this one. Think this is an old bee or what? Did find it interesting that there were bees bringing pollen in. I figured there would be no pollen to collect.
