Butterflies feed on the tears of animals for survival and mating

TLDR Butterflies feed on the tears of animals because they contain salt, which is essential for their nerves and muscles. Male butterflies drink tears to increase their mating frequency and perform more elaborate courtship displays. They also inject females with salt and sperm during mating, which can help their offspring survive.
