Nini Kaur shared this photo of a Luna moth taken at Bailey Farm Road in Monroe. These insects have moon-like spots and a lime green body and can be quite large. According to the web site Animals.Net, some Luna moths can have a wingspan of seven inches or more. Instead of having perfectly rounded wings, Luna moths have long protrusions that extend from each rear wing. In addition to their aesthetic appeal, these wing tails actually serve a purpose. Scientists believe the wing tails disrupt the echolocation of bats, one of the more skilled predators of Luna moths.
