Cicadas repeat this movement on either side 300 to 400 times a second to create their unique sound. Two eardrums are responsible for carrying sound from the cicada's abdomen to the outside.
By evaporative cooling, desert cicadas can reduce their bodily temperature by some 5 °C. [32] [33] Some non-desert cicada species such as Magicicada tredecem also cool themselves evaporatively, but less dramatically. [34] Conversely, many other cicadas can voluntarily raise their body temperatures as much as 22 °C (40 °F) above ambient ...
The earliest fossils of cicadas more closely related to Cicadidae than to Tettigarctidae date to the Jurassic period. The morphology of well preserved stem cicadids from mid-Cretaceous Burmese amber from Myanmar suggests that unlike many modern cicadas, they were either silent or only made quiet sounds. [2] The oldest modern cicadids date to ...
The sounds of H. maculaticollis and C. facialis songs are completely different as far as you can hear them with the human ear, but the base sounds of these two types of cicadas are almost the same, and if you play the sounds slowly, the sounds of H. maculaticollis if it is played back quickly, will be similar to the song of the C. facialis.
“It does make this kind of symphony.” The songs — only from males — are mating calls. Each periodical cicada species has its own distinct song, but two stand out: those of the orange-striped decims or pharaoh cicadas, and the cassini cicada, which is smaller and has no orange stripes on its belly.
