About 3-4 meters, butterfly view is quite good. Everything beyond that distance appears blurry for butterflies. Butterflies depend on their views for vital tasks, such as finding married mates of the same species or finding their food flower. In addition, butterflies can also see a vast range of ultraviolet colors, such as the human eye. They themselves have ultraviolet marks on their wings to get to know each other and to know their potential partners. Flowers also have ultaviolet signs that can be used to attract pollinating animals such as butterflies.
