Scientists have discovered a butterfly species which has tiny ears on its wings and can distinguish between high and low sounds. “Scientists thought butterflies were deaf until 1912 when the first butterfly ears were identified. Only in the past decade or so have researchers examined the anatomy and physiology of butterfly ears, which they are finding to be quite diverse and present in several butterfly species,” MSNBC reports. The latest discovery was made on a bright blue morpho butterfly – technical name Morpho peleides – which is native to Central and South America.
