Changes
* Nordic bees often stay in a winter cluster longer than other subspecies.
* They need proper, peaceful winter rest, especially before the [[cleansing flight ]] in spring when the hind gut is filled with feces.
* The comparatively small winter cluster sets down near the flight entrance.
* The size of the winter cluster is, on average, smaller than that of many other subspecies’.
* The small and tight winter cluster can withstand high concentrations of Carbondioxide (CO₂).
* The bees in the cluster can stand more mineral components in winter food than other subspecies (adaptation to a long winter and to Calluna honey in winter feed stores)
* Nordic bees usually fly the [[cleansing flight ]] later or even without being noticed in comparison to other subspecies.
* The bees’ winter food consumption is lower and they are not in such a hurry to do the cleansing flight.
* Typically, very few individual bees die during overwintering.
* Nordic bees don't come out from the hive during overwintering, nor do they have “snow blanket” losses.
* The bee colonies' development during spring is slow, but the [[winter bees ]] are long-living.
* A small number of adult bees can take care of a large brood area in spring.
* Nordic bees are easy to manage in the spring, as they don’t starve, and they usually have lot of winter feed left immediately after the [[cleansing flight]],
* The bee colony develops strongly in the end of May and June.
