Temperatures were near 60 today so I took off my supers to place another pollen patty on top of the brood box. There were several large white larvae that appeared to be on top of or only slightly encased by irregular wax comb structure. I don't if I broke off the top of their wax casings or what. This is only my second year beekeeping. The larvae where white and about 3/4" long. Could these be queen cells I accidentally broke open, or regular brood cells?
