Honey bees know who you are and what you look like
Honeybees may look pretty much all alike to us. But it seems we may not look all alike to them. A study has found that they can learn to recognize human faces in photos, and remember them for at least two days.
The findings toss new uncertainty into a long-studied question that some scientists considered largely settled, the researchers say: how humans themselves recognize faces.
The results also may help lead to better face-recognition software, developed through study of the insect brain, the scientists added.
Many researchers traditionally believed facial recognition required a large brain, and possibly a specialized area of that organ dedicated to processing face information. The bee finding casts doubt on that, said Adrian G. Dyer, the lead researcher in the study.
He recalls that when he made the discovery, it startled him so much that he called out to a colleague, telling her to come quickly because “no one’s going to believe it—and bring a camera!”

Dyer said that if bees can learn to recognize humans in photos, then they reasonably might also be able to recognize real-life faces. On the other hand, he remarked, this probably isn’t the explanation for an adage popular in some parts of the world—that you shouldn’t kill a bee because its nestmates will remember and come after you.
Francis Ratnieks of Sheffield University in Sheffield, U.K., says that apparent bee revenge attacks of this sort actually occur because a torn-off stinger releases chemicals that signal alarm to nearby hivemates. Says Dyer, “bees don’t normally go around looking at faces.”
I knew it! I knew those bees from my childhood had it out for me.
