If you’ve ever been in a garden during a warm summer day, chances are you’ve heard the enchanting sound of cicadas. These buzzing insects create a unique symphony, filling the air with their rhythmic melodies. But have you ever wondered how cicadas produce such vibrant songs? In this article, we will unravel the secrets behind the mesmerizing music of cicadas.

What are cicadas?

Cicadas are insects belonging to the order Hemiptera and the family Cicadidae. They are famously known for their distinct buzzing or vibrating sounds. There are over 3,000 known species of cicadas, each with its unique song. These fascinating creatures spend most of their lives underground as nymphs, emerging only as adults to breed and sing.

Why do cicadas sing?

The primary purpose of cicada songs is to attract mates. Male cicadas produce these enchanting melodies to seduce female cicadas. It is a beautiful display of courtship, where the males compete to create the most alluring sounds to win the hearts of the females. The songs also serve as a means of communication between cicadas.

How do cicadas produce sounds?

The mechanism behind a cicada’s song lies in their specialized sound-producing organs called tymbals. These are located on the sides of the cicada’s abdomen. When a cicada wants to sing, it contracts its internal muscles, causing the tymbals to buckle inward. As the tymbals snap back to their original position, they create a distinct clicking sound. By repeating this action rapidly, cicadas produce their melodious songs.

What makes cicada songs so loud?

Cicadas are among the loudest insects in the world, producing sounds that can reach up to 120 decibels. This is equivalent to the noise level of a rock concert. The reason behind their loud songs lies in their resonating chambers. These chambers, located in their abdomen, amplify the sounds created by the tymbals. Furthermore, the hard exoskeleton of cicadas acts as a natural amplifier, increasing the volume of their songs.

Can all cicadas sing?

While all adult male cicadas have the ability to produce sounds, not all species are known for their singing. Some cicadas have songs that are barely audible to humans, while others produce songs that can be heard from a considerable distance. The songs of cicadas also vary in pitch, rhythm, and duration, making each species unique in its musical abilities.

Cicadas, with their fascinating lives and enchanting songs, continue to captivate our imagination. The intricate process of how cicadas produce their melodies and the purpose behind their songs adds to the awe and wonder of these remarkable creatures. So, the next time you hear the soothing chorus of cicadas on a warm summer day, take a moment to appreciate the hidden symphony unfolding around you.
