Butterflies perceive ultraviolet light, a range of wavelengths invisible to humans. Many flowers display ultraviolet patterns that guide butterflies directly to nectar sources, increasing feeding efficiency. Butterfly wings may also reflect ultraviolet signals used for mate recognition and species identification. This advanced visual system helps reduce competition, improve reproductive success, and support navigation within complex environments. By accessing information hidden from many predators and other animals, butterflies gain a significant evolutionary advantage.
