Why Are Cicadas So Bad This Year

The low hum started subtly, almost unnoticeable amidst the usual sounds of spring. But then it grew, rising in volume and intensity until it was impossible to ignore—a deafening chorus that seemed to vibrate through the very ground beneath our feet. Yes, the cicadas had arrived, and this year, their presence felt particularly overwhelming.

For many, the emergence of cicadas is a fascinating natural phenomenon, a chance to witness one of nature's most peculiar life cycles. Yet, for others, it’s an all-out invasion. The sheer number of these buzzing insects, their constant noise, and their tendency to turn landscapes into their personal playgrounds can be quite distressing. This year, reports from various regions suggest that cicada populations are not only large but exceptionally so, leading many to wonder: Why are cicadas so bad this year?

The Perfect Storm: Understanding Cicada Emergence

To understand why cicadas seem particularly "bad" this year, it's essential to break down the fascinating life cycle of these insects. Cicadas belong to the order Hemiptera, and while there are many species, the ones that capture public attention most dramatically are the periodical cicadas. These cicadas, true to their name, emerge in predictable cycles, either every 13 or 17 years, depending on the specific brood.

The Underground Life

The life of a periodical cicada begins underground as a nymph. Here, they spend their next 13 or 17 years feeding on xylem, the fluid found in plant roots. Think about it: the nymphs go through several instars, shedding their skin as they grow larger. Which means after hatching from eggs laid in tree branches, the nymphs drop to the ground and burrow into the soil. Here's the thing — this subterranean existence is a slow, patient process. The soil provides a stable environment, protecting them from many surface predators and temperature extremes.

Synchronized Emergence

What makes periodical cicadas truly remarkable is their synchronized emergence. Think about it: after more than a decade underground, the nymphs emerge en masse in the spring. By appearing in overwhelming numbers, the cicadas increase their chances of finding mates and reproducing. This synchronized emergence is a survival strategy. Predators, even in large numbers, can only consume a fraction of the cicada population, leaving plenty to continue the cycle.

Why This Year?

Several factors can contribute to the perception that cicadas are "so bad" in a particular year. If two or more broods emerge in the same year and their territories overlap, the sheer number of cicadas can be staggering. In real terms, cicadas emerge when the soil temperature at a depth of about 8 inches reaches 64 degrees Fahrenheit. Favorable weather conditions also play a crucial role. Here's the thing — different broods of periodical cicadas exist in different geographic areas and on different schedules. One of the most significant is the convergence of multiple broods emerging simultaneously. Soil temperature is another critical factor. Mild winters and wet springs can increase nymph survival rates, leading to larger emergences. A consistently warm spring can trigger a mass emergence over a relatively short period, making the cicada presence more noticeable.

The Noise Factor

The male cicadas are responsible for the loud, buzzing chorus that accompanies their emergence. The collective sound of thousands or even millions of cicadas singing simultaneously can reach deafening levels. Each species has a unique song, which they use to attract females. Here's the thing — they produce this sound using tymbals, vibrating membranes on their abdomen. This intense noise can be particularly disruptive in urban and suburban areas, where it interferes with daily activities and causes stress for some people.

Comprehensive Overview of Cicada Behavior

Cicadas are more than just noisy insects; they represent a complex and fascinating aspect of ecological behavior. Their unique life cycle and synchronized emergence have intrigued scientists for centuries, leading to extensive research into their biology and behavior.

Evolutionary Advantages

The periodical cicadas' life strategy offers several evolutionary advantages. Spending the majority of their lives underground protects them from surface predators and environmental fluctuations. Which means the synchronized emergence overwhelms predators, ensuring that a significant number of cicadas survive to reproduce. The long life cycle may also provide a form of predator avoidance; predators with shorter life cycles cannot rely on cicadas as a consistent food source.

Impact on Ecosystems

Cicadas have a significant impact on the ecosystems they inhabit. Cicadas also serve as a food source for various animals, including birds, reptiles, and mammals. This nutrient boost can benefit plants and other organisms in the ecosystem. Their emergence provides a massive influx of nutrients into the soil as their bodies decompose. On the flip side, when the nymphs feed on tree roots, they can prune them, which may promote plant growth. Their emergence can trigger a temporary boom in predator populations.

Myths and Misconceptions

Despite their prevalence, cicadas are often the subject of myths and misconceptions. Plus, cicadas, on the other hand, do not swarm in the same way and generally do not cause widespread agricultural damage. Locusts are grasshoppers that form large swarms and can cause significant damage to crops. Another misconception is that cicadas bite or sting. One common myth is that cicadas are locusts. Cicadas do not have stingers, and while they have mouthparts for sucking plant fluids, they rarely, if ever, bite humans.

The Brood X Phenomenon

One of the most famous broods of periodical cicadas is Brood X (Brood 10), which emerges every 17 years. Its emergence is particularly notable because it is one of the largest and most widespread broods, covering a significant portion of the eastern United States. The Brood X emergence years often bring the most intense cicada activity, with massive numbers of cicadas appearing in forests, parks, and residential areas.

Cicada vs. Annual Cicada

make sure to differentiate periodical cicadas from annual cicadas. Annual cicadas, as the name suggests, emerge every year. Still, their emergence is less synchronized and their numbers are typically much smaller than those of periodical cicadas. Annual cicadas also tend to be green or brown, blending in with their environment, while periodical cicadas are often black with red eyes, making them more conspicuous.

Trends and Latest Developments

In recent years, several trends and developments have influenced cicada populations and their impact on human society. Climate change, urbanization, and deforestation are all factors that can affect cicada emergence patterns and population sizes.

Climate Change Impact

Climate change can disrupt the timing of cicada emergences. Because of that, changes in precipitation patterns can also impact cicada populations. Warmer temperatures may cause cicadas to emerge earlier in the spring, potentially disrupting their synchronization with other species and affecting their survival rates. Droughts can reduce nymph survival rates, while excessive rainfall can flood their underground burrows.

Urbanization and Habitat Loss

Urbanization and deforestation can reduce the habitat available for cicadas. Because of that, as forests and fields are converted into roads, buildings, and parking lots, cicada populations may decline. The loss of trees also reduces the availability of food for cicada nymphs, further impacting their survival rates.

Citizen Science Initiatives

Citizen science initiatives have become increasingly important in tracking and studying cicada emergences. Still, volunteers can report cicada sightings, collect data on population sizes, and contribute to research efforts. These initiatives help scientists monitor cicada populations and understand their distribution and behavior.

Public Awareness Campaigns

Public awareness campaigns can help educate people about cicadas and dispel common myths and misconceptions. These campaigns can also provide information on how to minimize the impact of cicada emergences on daily life, such as protecting young trees and avoiding the use of pesticides.

Research and Technological Advancements

Advances in technology are providing new insights into cicada biology and behavior. Think about it: researchers are using genetic analysis to study cicada populations and track their movements. Acoustic monitoring systems are being used to study cicada songs and understand their communication patterns. These technological advancements are helping scientists gain a deeper understanding of these fascinating insects.

Tips and Expert Advice for Coping with Cicadas

While the emergence of cicadas can be overwhelming, there are several strategies you can use to cope with their presence and minimize their impact on your life.

Protect Young Trees

Young trees are particularly vulnerable to damage from cicadas. Plus, to protect young trees, cover them with netting or cheesecloth. Female cicadas lay their eggs in tree branches, which can cause the branches to split or break. This will prevent cicadas from laying their eggs in the branches.

Avoid Pesticides

While it may be tempting to use pesticides to control cicada populations, this is generally not recommended. Pesticides can harm beneficial insects and other wildlife, and they are not very effective against cicadas, which emerge in such large numbers that it is impossible to eliminate them all.

Use Noise-Canceling Technology

If the cicada noise is particularly bothersome, consider using noise-canceling headphones or earplugs. This can help reduce the level of noise and make it easier to concentrate on your work or relax.

Appreciate the Phenomenon

Try to appreciate the emergence of cicadas as a unique and fascinating natural phenomenon. While they may be noisy and disruptive, they are also an important part of the ecosystem. Take the opportunity to learn more about cicadas and their life cycle.

Plan Outdoor Activities

If you have outdoor events planned during a cicada emergence, consider rescheduling them or moving them indoors. If that's not possible, be prepared for the noise and the presence of cicadas. Provide guests with earplugs or noise-canceling headphones if they are sensitive to the noise.

Educate Children

The emergence of cicadas can be a great opportunity to educate children about nature and the environment. That's why take them outside to observe the cicadas and explain their life cycle. This can help them develop an appreciation for the natural world.
