Imagine yourself sitting outside on a warm summer evening, surrounded by the rhythmic sounds of nature. Among the various symphonies, one sound stands out – the melodic chorus of cicadas. But have you ever wondered how these fascinating creatures are able to produce such a unique and beautiful song? Let’s unveil the melodious secrets of cicadas and explore the mechanics behind their enchanting symphony.

What are Cicadas?

Cicadas are insects belonging to the order Hemiptera and the family Cicadidae. They are known for their large size, characteristic appearance, and most notably, their extraordinary singing ability. With over 3,000 different species worldwide, cicadas are found on every continent except Antarctica.

Why Do Cicadas Sing?

Cicadas are primarily known for their singing, which serves both as a means of communication and courtship. Male cicadas produce these distinctive sounds to attract females for mating. Each species has its own unique song, making it possible to identify them based on their sound.

How do Cicadas Make Sounds?

Cicadas produce sounds through a fascinating structure called a tymbal. The tymbal is composed of ribbed membranes found on either side of the abdomen. By contracting and relaxing their muscles, cicadas are able to cause these membranes to buckle in and out rapidly. This results in the production of sounds that can be amplified to reach a volume of 90 to 100 decibels – that’s as loud as a lawnmower!

What Makes Cicada Songs So Loud?

Cicadas are well-known for their loud and piercing songs, which can be heard over long distances. This incredible volume is achieved through a combination of factors. Firstly, their specific body structure, including the hollow abdomen, helps to amplify the sound. Additionally, the male cicadas gather in groups, known as choruses, which enhances the overall volume of their songs.

Are There Different Types of Cicada Songs?

Yes, there are actually different types of cicada songs. The two main types are known as “calling songs” and “courtship songs.” Calling songs are used by male cicadas to attract females from a distance, whereas courtship songs are produced when a male interacts with a female at close range. These songs vary in duration, pitch, and pattern, depending on the species.

Do Female Cicadas Sing Too?

While male cicadas are the primary singers, some species of female cicadas are also capable of producing sounds. However, their songs are typically much softer and less frequent than those of males. Female cicadas sing to communicate with males during the mating process.

The magical songs of cicadas add a touch of enchantment to summer evenings. Now that you know the secrets behind their melodious performances, you can appreciate the incredible mechanisms that enable these insects to produce their unique sounds. So next time you hear the mesmerizing chorus of cicadas, take a moment to marvel at the nature’s symphony in action.
