The Luna Moth's Tail: A Bat Evasion Masterpiece.
Luna moths use their long, trailing tails to misdirect bat attacks, but researchers have found that the tails have no additional benefits beyond survival and do not confer any sexual selection advantages. The visually elaborate tails do not put Luna moths at a disadvantage in avoiding visually oriented predators that hunt during the day. The studies suggest that these stunning and complex structures evolved for a single function in Luna moths.
