Has anyone seen this before? A seemingly supersedure cell (is that what it is?) on an empty foundation? Could there possibly be an egg/larvae in there? On a foundation that has not been drawn out? I am a 2nd year beekeeper, so all these spring hive shenanigans are new to me. Long story short, I found swarm cells during my first spring inspection. I didn't know what they were at first & tore them down, but after some research, I realized what they were and added space. They rebuilt more swarm cells AND what appeared to be 1 supersedure cell on a frame with empty foundation. I figured the bees knew what they were doing, so I decided to let the bees continue on course with making a new queen, but I split the hive into two & put the old.queen in the new hive with all the goods. After the split, the bees in the first hive built out this "supersedure" cell into whatever that thing is now (in the 2nd picture) and, unlike the first time I saw it, it was covered in bees (I blew them out of the way to get a picture), but still no comb on the rest of the foundation. After the split, they also built 4 normal looking queen cells (all capped) on other brood frames. [The swarm cells had all been torn down by the bees, phew!] So, I'm just wondering what the heck is this and is there a developing queen in it? Could there possibly be? Thank you for your help!
