Russian bees are evolved to deal with its colder weather and unpredictable ontological conditions they were subjected to; they had to come up with their own unique survival strategies such as "just in case queen cells" and these:

"Russians are excellent at over-wintering. They are frugal with their winter stores. Be ready for an explosive buildup. In a 2001 study of Russian honey bees, V. Kutznetzov et al. reported that the Russians are long-lived. “The last winter bees die a month later than the Italians.” This enhances spring build-up and honey production."

"They start slow but when pollen and nectar become available the queen becomes very active. The workers draw out foundation quickly and the queen fills up the frames fast. As a result you may have up to 2,500 workers emerging each day. That is an explosion. “

* If animals entered a new environment—or their old environment rapidly changed—those that could flexibly respond by learning new behaviours or by ontogenetically adapting would be naturally preserved. This saved remnant would, over several generations, have the opportunity to exhibit spontaneously congenital variations similar to their acquired traits and have these variations naturally selected. It would look as though the acquired traits had sunk into the hereditary substance in a Lamarckian fashion
