I thought this was cool! http://www.guardian.co.uk/environment/2012/apr/18/black-honeybees-rediscovered-in-britain Reminds me of the 'black German bees' an 80 yr old beekeeper near me talks about his bees being descended from. His bees are indeed darker then most italians around here. My own bees seem to be getting darker every year as my new queens mate with local drones, less yellow/golden. I do know of several long-term feral hives within 5 miles of me, but they're so high up I can't see them closely to look at their color.
