Cicadas bark non-stop mainly to court mates. Cicadas can only live for about a month, so they bark non-stop in order to reproduce.

Only the male cicada can cry, but the female cicada cannot cry.

And the cicada’s cry is also affected by the weather. The hotter it is, the louder the cry is. It will also emit a cry after being frightened.

Why can cicadas scream so loudly?

This is also caused by the physiological structure of the male cicada, which has two semicircular generators on its abdomen. It is very similar to the small trumpet made of bamboo that we played when we were children in the countryside. A semicircular film is placed in the bamboo, and it will make a loud sound when it is blown. The body structure of cicadas is similar to this principle. The sound when shouting is very loud.
