I removed a frame of brood with two QC's from an Italian hive to a nuc. This was yesterday. The QCs were very small but larger than drone brood [If I can ever figure out how to post photos from my phone I will do so]. In any event, postedsome photos to a FB group and was getting feedback that they were indeed QC's. Unfortunately in my indecision I had added the frames back to the hive today. So after realizing my mistake I went back in to again remove them but instead found the bees in the process of tearing them down, removing the wax around the larvae. Main Hive is confirmed to be Queen right.
Anyone ever seen this behavior before?
