The Temperature Relationships of the Honeybee Cluster Under Controlled External Temperature Conditions

It has previously been supposed that as external air temperatures lower following the clustering of the honeybee colony, the cluster temperatures rise. Observations for 2075 hours under controlled temperature conditions show that cluster temperatures remain remarkably constant regardless of external temperatures within certain limits. When there is a significant change in the cluster temperatures, it is in direct relationship with the change in the air temperature, rather than inverse.
