Two beehives believed to be at least 80 years old were rehomed after they were discovered in Old Main at the University of Colorado Boulder in August.
“It’s an estimation, but after seeing lots of different combs after different ages, it was at least 80 or maybe older,” he said, later adding, “Anytime you deal with older structures, the chances are they’ve had bees in them for quite some time.” McGaughey said he can tell how old a beehive is based on the colors of its layers. When bees make a honeycomb it starts out white, and as it gets older and more generations build on top of it, the comb gets darker brown until it turns black.
