Introduction to Cicadas
Imagine a warm summer evening, the sun is setting, and a symphony of sound begins to echo through the air. This is not the melodic chirping of crickets or the gentle hum of bees, but a full-blown orchestra of noise that can reach up to 100 decibels – as loud as a motorcycle. This cacophony is the song of the cicadas, a group of insects known for their striking life cycle and their deafening buzz.
Cicadas are insects belonging to the order Hemiptera, which also includes aphids, leafhoppers, and shield bugs. They are known for their large size, with some species reaching up to 2.5 inches in length, and their distinctive, bulging eyes. There are over 3,000 known species of cicadas, but they are perhaps best known for their unique life cycle, specifically the periodical cicadas that emerge in large swarms every 13 or 17 years.
For most of their lives, cicadas are underground, living as nymphs and feeding on the sap from tree roots. When the time comes, they emerge from the ground, shed their exoskeleton, and take to the trees as adults to mate and lay eggs. This final stage of their life is when we hear their infamous buzz, a mating call produced by the males to attract females.
While cicadas are a common part of life in many parts of the world, their periodic mass emergences, known as ‘broods’, can be a significant event. These broods can contain millions, even billions, of cicadas, leading to what is often referred to as a ‘cicada invasion’. This article will delve into the fascinating world of cicadas, exploring why they make such a deafening buzz, how we can cope with it, their impact on the environment, and the implications for public health. So, let’s dive in and learn more about these remarkable insects.

Understanding the Cicada Invasion
The cicada invasion, often referred to as a cicada bloom, is a natural phenomenon that occurs every 13 to 17 years, depending on the species. This event is marked by the emergence of billions of cicadas from their underground burrows, where they have been living as nymphs feeding on tree roots. The sudden appearance of these insects in such large numbers can be quite alarming, but it’s all part of their unique life cycle.
There are over 3,000 species of cicadas worldwide, but the ones that are most commonly associated with these mass emergences are the periodical cicadas of the genus Magicicada in the United States. These are divided into 15 different broods, each of which emerges in a different year and in a different region of the country. For example, Brood X, which is one of the largest and most widely distributed, emerged in 2021 in parts of the East Coast and Midwest.
The reason for this synchronized emergence is not entirely understood, but it’s thought to be a survival strategy. By emerging in such large numbers, cicadas overwhelm their predators, ensuring that enough of them will survive to reproduce. This phenomenon, known as predator satiation, is one of the most remarkable examples of this strategy in the animal kingdom.
Once they have emerged, the adult cicadas spend their brief lives (usually four to six weeks) mating and laying eggs. The females cut slits in the branches of trees and deposit their eggs inside. When the eggs hatch, the newborn nymphs drop to the ground and burrow into the soil, where they will remain for the next 13 to 17 years, feeding on tree roots and slowly growing, until it’s time for them to emerge and start the cycle anew.
While the cicada invasion can be a nuisance due to the noise and the sheer number of insects, it’s also a fascinating natural spectacle that provides a unique opportunity to observe and learn about these remarkable creatures.
The Deafening Buzz of Cicadas
As the cicada invasion descends upon us, one of the most prominent features that captures our attention is the deafening buzz created by these fascinating insects. The sound can be overwhelming and even disruptive, but it is an integral part of the cicada life cycle.
Cicadas are unique among insects in their ability to produce such a loud and persistent noise. The sound is produced by the males, who have specialized structures called tymbals on the sides of their abdomen. These tymbals consist of a series of ribs that can be rapidly vibrated, creating a distinctive buzzing sound.
The purpose of this deafening buzz is to attract females for mating. The males gather in large groups called choruses and synchronize their buzzing to create a chorus effect, which can reach volumes of up to 100 decibels. This impressive volume is comparable to the sound of a lawnmower or a motorcycle.
The buzzing sound of cicadas serves two main purposes. Firstly, it helps the males to attract females from a distance. The loudness and intensity of the buzz indicate the fitness and quality of the male, making it an attractive choice for potential mates. Secondly, the chorus effect created by multiple males enhances the overall sound, making it even more noticeable and difficult to ignore.
The deafening buzz of cicadas can be a source of annoyance for some people, especially those living in areas where the cicada population is particularly dense. The noise can be constant and may persist for several weeks or even months, depending on the species and the region.
However, it’s important to remember that the cicada invasion is a natural phenomenon that occurs periodically and has its own ecological significance. While the noise may be overwhelming, it is temporary and part of a larger cycle of nature.
Many people find creative ways to cope with the deafening buzz of cicadas. Some choose to use earplugs or noise-cancelling headphones to minimize the impact of the sound. Others may play soothing music or use white noise machines to create a more pleasant auditory environment.
It’s also worth noting that the buzzing sound of cicadas can vary in intensity and pitch. Some species produce a high-pitched whine, while others have a lower, more resonant tone. The specific sound profile can differ depending on the species and the individual cicada.
Despite the challenges posed by the deafening buzz of cicadas, it’s important to appreciate the unique nature of this phenomenon. The cicada invasion is a remarkable event that offers a glimpse into the wonders of the natural world. So, embrace the buzz and marvel at the resilience and beauty of these fascinating insects.
