In my inspection yesterday, besides finding some varroa, I found this unusual formation. I thought it mught be a queen/swarm cell, but it doesn't hang down like I've seen in pictures. Besides, I don't see that the colony is strong enough to swarm, and they certainly aren't overcrowded in there that I can see (I only started the colony from a package a little over seven weeks ago). The queen is fine and has been active, laying plenty of eggs in both boxes. I took a few pictures; the closeup picture is a little out of focus because the camera just doesn't do extreme closeups very well. The thing I'm looking at is the bump on the lower right hand corner of the frame, on the foundation. The second picture is of the full frame showing the bump's location in relation to the full frame. It was in the upper brood box. Can anyone give me an idea of what this is, and what I should do with it?
