On closer inspection, the girls are also scraping the propolis off of old bottom boards and inner covers and frames that I have out. This makes me wonder just what they are using all this propolis for. Because that’s a whole lot of propolis that seems to be vanishing in to the hive.
Notice that the lovely lady in image two has blobs of cleaned propolis in her pollen baskets. Just goes to show that they can use them for much more than just pollen~
