I watched a bee drag this pupae out of the hive and drop it. Thought I’d check it out. I realize there are a number of things that could cause a bee to die. I just wondered if anything jumps out to you experienced beekeepers from the pictures.
This hive was s swarm I caught in May. In July I added a few frames of comb/pollen/nectar from a failed spring NUC I bought to this hive to give it a boost. It seems a good size to me. Busy and filling up frames of honey in the top brood box at least. I have a super of undrawn frames on still but no activity in there.
