Changes
* 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,
