Sitting near the hives today I spotted a worker walking around on the ground. Her abdomen was missing completely. Just a head and thorax. She was getting around just fine, but couldn't fly.
A little later I saw a drone on his back. He was trying to right himself without much luck. I picked him up and laid him on the palm of my hand. He was broken at the joint between thorax and abdomen, and attached by a thread on the ventral side. It was creepy.
Earlier I had gone through one of the hives. Perhaps these two just got caught between moving frames. Please tell me there is no such thing as "Broken Bee Disease" or "Glass Bee Syndrome".
