are some bee user to colder weather than other?
Sure. I always hear about how better it is to get bees from your area because they are more acclimatized to the weather. The breed can make a difference too. Russians for instance are good cold climate bees. From Wikipedia about Russian Honey Bees "The Russian honeybee from the Primorsky Krai, a region in the southern extreme of the Russian Far East, belongs to the species Apis mellifera.
The Russian honeybee has evolved traits of resistance to natural mites owing to heavy selection pressures. It has lived for more than 150 years in a region that is home to the varroa mite and the tracheal mites (Acarapis woodi).
In 1997, the USDA's Honeybee Breeding, Genetics & Physiology Laboratory in Baton Rouge, Louisiana imported Russian bees to North America.
The Russian bees resemble the dark Carniolan strain. They use less propolis than typical Italian honey bees. They are not prone to sting. The bees show exceptional winter hardiness, hibernating in small winter clusters, and produce a high nectar haul per bee.
They are more apt to building queen cells throughout the brood season and may have a higher tendency to swarm."
