Hi everyone, weird observation I noticed today on my inspection of my overwintered top bar hive. It's a prosperous hive I have been managing to prevent swarming all spring and I came in yesterday to use it for starting a cell builder. It has many empty queen cups that I've seen most of spring, but out of nowhere, i saw a capped queen cell on the edge of a comb. I was very surprised and opened it, revealing a large larvae inside. There were no other capped swarm cells or any with eggs or larvae I could see. I found fresh eggs in other parts of the hive so I know the queen has been there at most three days ago. I can't find a good explanation for this single swarm cell unless it was a superecedure or they were planning on breaking it down soon. Has anyone seen this before?
