Re: Dead Larva
I have had a couple of days that it got so cold the bees did not forage. ON those days I also noticed that they woudl bring a few Pupa our of the hive. Not always dead ones either. I posted about it here but the only answer i got was they may do this when they are stressed. This might also be hygienic behavior and they are removing brood they consider "Unclean". I have not yet heard anything that would cause me to worry though.
