Reply to comment by Hattix in TIL that despite having brains the size of poppy seeds, bees are able to recognize and remember human faces. In a study, researchers paired images of human faces with sugar-laced water, and bees were able to recognize and remember the faces even when the reward was no longer present. by MaleficentTop6074

Bees use visual cues to recognise flowers. They can also see polarised light and use that to navigate.

I'm wondering if the pictures were similar enough that the only way to tell them apart was by recognizing the face.

no doubt but I don't get how bees can recognize people when I have issues lol. Would make much more sense that they rely on olfactive cues, like other social insects, ants. I bet giant apes are quite smelly.

I'm not sure how applying your personal experience with faces (which is quite unusual for humans, who are great at recognizing faces) makes sense when we're talking about bees.

Also, the studies used pictures of faces and stylized faces, so no actual humans were being recognized - or smelled.

damn, I should have read the whole thing, the study was properly made then, sometimes it's just bad science that can be explained otherwise but in this case... I don't feel bad if i'm wrong, I've often read that bees can use visual cues to identify flowers so no doubt there's some truth there. I shouldn't have assumed they used people.

I guess they see us as giant flowers and can quickly learn which "flowers" are good. they can probably share that info amongst the colony as well. Fascinating how simple mechanisms can evolve and become so resilient. Probably a lot to learn from social insects if we want to make better electronics down the path.

Bruh, if a bee was 30cm (12inchs) away from you face it’d be able to see freckles on your face that you can’t even see because their vision is optimized to see in the UV spectrum. Not only that but they are able to recognize more objects at once than a human can so those freckles could easily paint a unique enough picture for them to recognize it visually.

Copy/Paste from somewhere else

“The multi-faceted eyes of honeybees consist of up to 8000 individual eyes, the so-called «ommatidia». Although the bees have a large field of vision, they are short-sighted and can only see sharply in the centimeter range. A human can distinguish two points at a distance of 18 m as separated, while a bee can do this at only 30 cm. In contrast, bees have a much better temporal resolution. Bees are able to resolve up to 200 images per second, while humans can only perceive 20 images per second. This high resolution gives bees a quick reaction time and is also important for the estimation of distances (see below under orientation).”

I think you’re the one being dumb here homie

The don't recognise faces, they recognise the patterns that make up those faces.
