Very good publication and interesting rocking chair, I know that the cicadas are known for the sound they emit, this is thanks to the air sacs that are in the abdomen and that are inflated and deflated through the membranes that entomologists call timbales. And the power and intermittence of that sound is for some annoying people, it accelerates with the increase in temperatures. That is why we believe that cicadas sound with greater intensity during heat waves and in the central hours of the day. Thanks for the information since I did not know much about these insects. Thanks for this contribution. Regards
