I would highly doubt it is the same bees inhabiting the tree.. Meaning the Same colony through swarming etc, but the fact remains it HAS had bees in it for a VERY long time. I remember climbing this tree as a kid, and being run out of it... not by the bees, but by parents and grandparents BECAUSE it had bees in it.
I know there are family pictures with the tree in the background, but do not know if they will show bees around the opening..
At one point this tree was the center of a steel pile, with misc pieces of scrap tossed about it to a depth of nearly four feet.. When my step grandfather passed away, the farm went to my father, and he started cleaning.. this cleaning continues today, and if you have not heard the story, is how I ended up with a water tank of bees...
Mom said she was on the porch reading her book. Dad was busy loading scrap steel on the trailer... she looked up in time to see him head across the yard with the tank... he paused.. he dropped the tank and flapped his arms... Then, she said, he lit out like his tail was on fire... his arms were waving and he was going faster than she had seen him go in 65 years..
She dropped the book and ran into the house and locked the door as he was yelling BEES! BEEEEEES! as he ran toward her...
Thinking better of it she unlocked the door before he arrived and ran for the bedroom, locking herself in there...
They both stood watching through the window as I picked up the tank and gently put it back where it had been. I waited until dark, screened it up and took it home...
I have since seen a swarm from that tree leave for parts unknown, and I have seen a swarm from that tree take up residence in a hydraulic oil barrel about 20 feet from the tree. I know one swarm took up residence in an old delivery truck that used to sit on the property, and another took up residence in the gas grill that always sat out on the porch.
Hoping from here forward they will choose my swarm boxes.
If I catch a swarm from this tree, My first task is going to be producing a dozen queens from it to see how resistant they are.
