Re: German dark honey bee in NC
You will find that there is very little of the AMM genetics left here in the U.S. They had a few advantages, but an overwhelming number of faults. They were extremely aggressive. They swarmed at the drop of a hat. They were very runny on the combs. Manipulating colonies was a crapshoot, you might be stung hundreds of times or you might get off scot free. They tended to collect the blackest honey around. I don't miss them.
On the plus side, they maintained small colonies overwinter, had the most explosive imaginable spring buildup, were extremely thrifty with stores, would fly at temps as low as 35 degrees, would always make a small surplus of honey, had the longest lived queens, and were exceptionally good at raising queens.
There are a few feral colonies just north of here (NorthWest Alabama) that show most of the AMM traits. They are obviously heavily crossed with Italian bees.
