I like to compare it to the "welcome mat" that gets darker the more we walk on it. Remember, the bees come in from the field with dust they've collected on their feet. The more they walk on the wax surface, the more gets wiped off their feet.All new wax is white. It darkens with age..
Didn't you hear the results of the experiment? Or did the experimenter only report on his question? Of course there's one sure way to get the answer--try it out yourself---and don't forget to report the results to the forum.I recently heard of someone who put green food coloring in their sugar syrup so that they could tell if the bees were backfilling the syrup into the honey. Has anyone heard of this?
