They can see in the near ultraviolet. You use the term “attack,” which is not 100% clear. For more experimental uses of insects, see the Cockroach-controlled mobile robot and Bees may be keys to cooperative robots. The way humans see the world is not the same as how other species on the planet see things. Bees can be trained to recognize human faces, so long as the insects are tricked into thinking that the faces are oddly shaped flowers, new research shows. Read more about how Honey bees recognize people . It is my understanding that bees see the ultraviolet end of spectrum just like any other colour. They can see: yellow, blue-green, blue, violet, ultraviolet, and also a color known as “bee’s purple,” a mixture of yellow and ultraviolet, but not red. "You see things in humans which you might attribute to having complex, mammalian brain, but until you go and test it in bees, you can't exclude the fact that a simple brain can do it." However, there can other perceptions that show reality differently. A Study performed by Adrian Dyer, Martin Giurfa, and Aurore Avarguès-Weber, published in the Journal of Experimental Biology in 2010 , indicated bees were capable of recognising face-like patterns. “To the bees the faces were spatial patterns (or strange looking flowers),” he added. I also know that one cannot get a sun tan through the window because much of the ultraviolet light is taken out by the glass. Bees can see colors in the spectrum ranging from ultraviolet to orange and have been noticed to prefer purple, blue and yellow flowers. Bees trying to count “like humans” Early in February, we discovered that bees are capable of adding up and subtracting, in other words they can perform mathematical operations. A honeybee will never sting a person (or a beast) without a reason. [1] An experiment carried out by a Franco-Australian team allowed us to observe this ability. There’s a saying that “perception is reality”—meaning how we see things is how we believe them to be. They also tend to be drawn to symmetry , so there is some chance that a combination of bees’ preferred colors and symmetrical patterns could attract them to you. Bees and wasps can recognise people's faces – despite having less than one million brain cells, compared to 86,000 million brain cells that make up a human brain. It’s just that you don’t always know what that reason might be. Although honey bees perceive a fairly broad color range, they do not perceive them like humans do. The bees probably don’t understand what a human face is, Dyer said in an email. A little bit further than humans and most mammals. However, there is evidence to suggest that bees can recognise human faces in general, or more specifically, the composition of a human face. Not a huge range past what we can see.
