Butterflies Are Nearsighted but Can See Colors

Within about 10-12 feet, butterfly eyesight is quite good.4 Anything beyond that distance gets a little blurry, though.

Despite that, butterflies can see not just some of the colors that we can see, but also a range of ultraviolet colors that are invisible to the human eye. The butterflies themselves may even have ultraviolet markings on their wings to help them identify one another and locate potential mates. Flowers, too, display ultraviolet markings that act as traffic signals to incoming pollinators like butterflies.
