In the experiments, in which academics explore how the bees to determine if a bee nest or colleagues don't, the bees, and sometimes does not recognize it as their nest, colleagues, and, eventually, accidentally poking out their sisters! They also sometimes leave the bees in the hive, who are not peers of the time.
So, when trying to defend their nests from intruders, bees, sometimes by accident, markers, their fellow bees, but that's only because they're your sisters, and to the deep sea.
I can't say that I blame them for that. I don't know for sure whether or not I was able to get to know my sister as well, if only I had thousands and thousands of them.
