Why Do Cicadas Make Noise? (Insect Communication)

When the warm summer months arrive, the unmistakable sound of cicadas fills the air. But have you ever wondered why these fascinating insects produce such loud noise? In this article, we will explore the reasons behind cicada noise, the function of their singing, and the mechanism behind this unique form of insect communication.

Male cicadas use drum-like structures called tymbals on their abdomen to create a high-pitched buzz that can reach over 90 decibels. This buzzing serves as a mating call, attracting female cicadas who respond with wing flicks. While the noise may be a nuisance to some in rural and suburban areas, it is less likely to be heard in the city, as cicadas prefer trees and shrubs as their habitat.

Unlike other insects that produce noise by rubbing body parts together, cicadas pull on their tymbals, which are arranged like a musical instrument. This unique mechanism allows them to create two sets of notes playing simultaneously, similar to Tuvan throat singing.

Key Takeaways:

• Cicadas produce loud noises as a form of communication, particularly for mating purposes.
• Male cicadas use tymbals on their abdomen to create a high-pitched buzz that can reach over 90 decibels.
• Cicada noise serves as a mating call, attracting female cicadas who respond with wing flicks.
• Unlike other insects, cicadas produce sound by pulling on their tymbals, creating two sets of notes playing simultaneously.
• Cicadas prefer trees and shrubs as their habitat, making their noise less likely to be heard in urban areas.

The Singing Cicadas

The singing of cicadas is their claim to fame. Each species has its own distinctive song that attracts only female cicadas of the same kind. The high-pitched song, produced by male cicadas, serves as a mating call. Some larger species can produce calls exceeding 120 decibels, close to the pain threshold of the human ear. The sound is created by specialized organs called tymbals located at the base of the abdomen. Male cicadas chorus together to amplify the sound and increase their chances of attracting mates. The loud noise also functions as a deterrent for birds, making it difficult for them to hunt in groups.

The singing of cicadas is a mesmerizing symphony that fills the air during the warm summer months. Male cicadas use their specialized organs called tymbals to produce their signature songs. The tymbals, located at the base of the abdomen, are ribbed membranes that produce a high-pitched buzz when contracted. This buzzing sound serves as a mating call, attracting female cicadas in search of a suitable mate.

Some species of cicadas can produce calls exceeding 120 decibels, which is close to the pain threshold of the human ear. The volume of the song is an indication of the male cicada’s size and potential fitness as a mate. Female cicadas respond to the male’s song with wing flicks, signaling their interest and readiness to mate.

The chorus of male cicadas amplifies the sound, creating a symphony that can be heard over long distances. This chorus not only increases the chances of attracting a mate but also functions as a defense mechanism against predators. The loud noise produced by the cicadas makes it difficult for birds to communicate and hunt effectively in groups, providing the cicadas with a survival advantage.

Mechanism of Cicada Sound Production

Cicadas have a unique anatomy that allows them to produce their loud sounds. The key component of cicada sound production is the tymbals, ribbed membranes located at the base of the abdomen. These tymbals are responsible for generating the distinctive buzzing sound that cicadas are known for.

When a male cicada wants to produce sound, it contracts the muscles attached to the tymbals. This causes the tymbals to buckle inward, creating vibrations that produce the sound waves. The hollow back end of the cicada’s body acts as an amplifier, increasing the volume of the sound. The wings also play a role in directing the sound in different directions.

Unlike other insects that produce sound by rubbing body parts together, cicadas pull on their tymbals, which are arranged similar to a musical instrument. This unique mechanism allows cicadas to produce loud and distinct buzzing sounds that can be heard over long distances. In fact, the sound produced by cicadas is comparable to Tuvan throat singing, as they have the ability to create two sets of notes playing simultaneously.

The mechanism of sound production in cicadas is fascinating and demonstrates their unique adaptation for communication. By understanding the intricate process of cicada sound production, we can gain a deeper appreciation for the beauty and complexity of these remarkable insects.

Cicada Songs and Repelling Birds

Cicadas have different types of songs serving various purposes. The primary song is the reproductive call that attracts female cicadas. The volume of the song is an indicator of the male’s size and potential fitness as a mate. Female cicadas produce a softer clicking noise to get the attention of nearby males.

The cicada song is not only for attracting mates but also serves as a defense mechanism against birds. The loud noise is painful to birds’ ears and disrupts their communication, making it challenging for them to hunt in groups. In addition to the reproductive call, cicadas also have a distress sound as a warning to protect the population.

By producing a variety of songs, cicadas can ensure successful reproduction and survival. The primary song attracts mates, while the distress sound warns of danger, repelling potential threats. The loudness of the cicada songs serves as a protective mechanism against predators, particularly birds, by causing discomfort and interfering with their hunting strategies. The intricate communication system of cicadas highlights their adaptability and evolutionary advantage in ensuring their population’s survival.

Cicada Life Cycle and Reproductive Imperative

Cicadas have a unique life cycle that plays a crucial role in their reproductive success and survival. Some species of cicadas, known as periodical cicadas, have an exceptionally long life cycle of either 13 or 17 years. This extended development period is believed to be an adaptation to avoid synchronized emergence with predators and increase their chances of survival.

Once mature, female cicadas lay their eggs in the branches of trees, using their ovipositors to create small slits where the eggs are deposited. After hatching, the cicada nymphs fall to the ground and burrow into the soil, where they feed on tree roots for the duration of their underground phase.

After spending several years underground, the nymphs emerge from the soil as adults. This emergence is synchronized, with thousands or even millions of cicadas emerging at once, creating a spectacle known as a “cicada emergence” or “cicada outbreak.” The mass emergence allows for efficient reproduction, as male cicadas can easily find mates in large numbers. The loud and distinctive songs produced by male cicadas serve as a means of attracting females and increasing their chances of successful mating.

The Importance of Cicada Songs in Reproduction

The loud songs produced by male cicadas play a vital role in their reproductive success. These songs serve as a means of communication, allowing male cicadas to attract females from a distance. The songs are species-specific, meaning that each species of cicada has its own unique song. This ensures that male cicadas only attract females of the same species, increasing the chances of successful mating and preventing genetic mixing between different species.

The volume and intensity of the cicada songs are indicators of the male’s fitness and reproductive potential. Females are more likely to be attracted to males with louder songs, as this indicates their ability to provide resources and contribute to the survival of their offspring. The competition among male cicadas to produce the loudest and most appealing songs is a crucial aspect of cicada reproduction.

The loud songs produced by cicadas are not only essential for attracting mates but also serve as a form of species recognition and competition. Male cicadas chorus together, amplifying their songs and creating a cacophony of sound that can be heard over long distances. This chorus effect increases the chances of attracting females and ensures that the reproductive efforts of each individual cicada are maximized.

Overall, the cicada song is of utmost importance for the survival and reproduction of these fascinating insects. It not only serves as a means of communication and attracting mates but also plays a vital role in maintaining species boundaries and regulating competition within cicada populations.
