>>3) When the temperatures do drop sharply for an extended period of time the cluster will contract and will not be able to reach the stores that was not rearranged during the warm period. Why would the wrapped colony not rearrange the stores during the warm periods? >>If this cold period lasts to long they will die from starvation even though the stores were only inches away. This can happen even if they are wrapped if temperatures drop sharply for long periods. My point was that insulated colonies can withstand the cold long weather better. They hold a losser cluster, covering more surface space in the colony.
