Butterfly Discovered With Ears on Its Wings

And one species was recently discovered to have ears on their wings. The blue morpho butterfly from Central and South America has beautiful bright blue wings complete with a simple ear structure that picks up noise and relays it to the brain.

In the new study, Kathleen Lucas of the University of Bristol in England and her colleagues were interested in the odd-looking hearing membrane that sits at the base of the blue morpho’s wing. The tympanal membrane, as it is called, is oval-shaped with a dome at its center that kind of resembles the yolk at the center of a fried egg, Lucas said.

Researchers determined that the butterflies can distinguish high and low frequencies, uncommon in simple ears, and they speculate this could help them determine if a hungry bird is about to swoop down and attack.
