Bees Color Blind

Flowers have beautiful patterns invisible to the human eye, but eye-catching to bees. I was reading a children's book about insects to my daughter, and it said that bees see colors differently than humans do. My daughter immediately asked, in short succession: What colors do they see? Why? How do we know? I did some homework to find out, and discovered that bees see flowers much.

Abstract Behind each facet of the compound eye, bees have photoreceptors for ultraviolet, green, and blue wavelengths that are excited by sunlight reflected from the surrounding panorama. In experiments that excluded ultraviolet, bees learned to distinguish between black, gray, white, and various colors. To distinguish two targets of differing color, bees detected, learned, and later.

Bees, like many insects, see from approximately 300 to 650 nm, which means they cannot see the color red but can see other colors moving down the scale. Bees are not completely red blind, but they can discriminate yellow, blue, ultraviolet, and blueish colors. Humans base their color combinations on red, blue and green, while bees base their colors on ultraviolet light, blue and green.

This is the reason why bees can't see the color red. To understand why bees see colors humans cannot, we must step into their world, a world shaped by millions of years of co-evolution. It is a story that combines physics, biology, and the profound interconnectedness of life on Earth.

It is also a reminder of how limited our own perception is, and how much wonder exists just beyond the boundaries of our senses. Yes, bees can see color, to extent, but their vision is different than human color vision. They can distinguish between green, blue, and ultraviolet light, but they can't distinguish red from black.

Bees, more than any other life force on earth, get up close and very personal with nectar-producing flowering plants and trees. It makes you wonder: can bees see color or are they colorblind? Discover how bees see color, from trichromacy to ultraviolet light. Learn the science behind their unique vision and its impact on behavior, communication, and conservation efforts.

Bees see color. They have three cone receptors (the receptors responsible for processing colors) for green, blue, and ultraviolet light. Bees, however, perceive a shifted spectrum, generally from 300 to 650 nm.

This means bees are blind to certain long wavelengths visible to humans but can detect wavelengths invisible to us. Bees possess three types of photoreceptors in their compound eyes, similar to human trichromatic vision.
