Auchenorrhyncha are unusual in that the sexes communicate with each other using species-specific acoustic signals produced by a unique structure on the side of the abdomen called the ‘tymbal’ organ. Most of these calls take the form of vibrations that are inaudible to the human ear and are sent through the plant.
On the other hand, cicadas communicate through the air, males producing some of the loudest ‘songs’ of all insects.
