Biology of Cicadas

Cicadas are insects belonging to the order Hemiptera, which also includes aphids and leafhoppers. They are known for their stout bodies, broad heads, clear membranous wings, and prominent eyes. Cicadas are primarily classified into two families: the Cicadidae, which includes the well-known periodical cicadas, and the Tettigarctidae, commonly referred to as hairy cicadas.

The life cycle of cicadas is divided into three main stages: egg, nymph, and adult. After the eggs are laid in tree bark, the nymphs hatch and drop to the ground, where they burrow and spend several years feeding on root sap. This subterranean phase can last from a few years to over a decade, depending on the species. Once mature, the nymphs emerge from the ground, molt, and transform into adults, ready to continue the cycle.

The adults are known for their distinctive sounds, which play a crucial role in their mating rituals. These sounds are produced by male cicadas using specialized structures located on their abdomens. The amplified calls can vary in volume, frequency, and pattern, often depending on the specific species and environmental conditions.

How Do Cicadas Produce Sound?

The mechanism behind the cicada's sound production is fascinating and involves the use of tymbals. Tymbals are ribbed membranes located on the sides of the cicada's abdominal base. Male cicadas have powerful muscles attached to these tymbals, which they contract and relax rapidly, causing the membranes to buckle inwards and produce sound.

This rapid buckling and unbuckling create a series of clicks that are amplified by the cicada's largely hollow abdomen. The speed and rhythm of these clicks are modulated to produce the characteristic buzzing or droning sound associated with cicadas. The sound can reach up to 120 decibels, making it one of the loudest insect calls known.

Cicadas also have a unique ability to modulate their calls in response to environmental factors and social cues. For instance, a male cicada will often alter its call to compete with nearby males or to adjust to changing weather conditions. This adaptability ensures that their calls are effective in attracting females and deterring rival males.

What Do Cicadas Sound Like in Different Species?

The sound of cicadas can vary significantly between species, each possessing its own unique acoustic signature. Some species produce a long, continuous drone, while others emit a series of rhythmic clicks or trills.

• Common Dog-Day Cicada: Known for its high-pitched and rapid buzzing sound, often compared to a power line hum.
• Periodical Cicadas: These cicadas have a more melodic and whirring sound, with some describing it as a "pharaoh pharaoh" chant.
• Desert Cicadas: These produce a softer, more subdued sound, resembling a gentle rattle or whisper.

The diversity in cicada sounds is largely attributed to differences in tymbal structure, body size, and environmental adaptations. Each sound serves a specific purpose in the cicada's life cycle, primarily revolving around mate attraction and territory establishment.

Why Are Cicada Sounds Important?

Cicada sounds are more than just a summer soundtrack; they play a vital role in the life cycle and ecological interactions of these insects. The primary function of cicada sounds is to facilitate mating. Male cicadas sing to attract females, who are drawn to the loudest and most persistent callers.

In addition to their role in reproduction, cicada sounds also serve as a defense mechanism. The loud calls can deter predators, making it difficult for them to locate the cicadas. Furthermore, the mass emergence of cicadas during certain years can overwhelm predators, ensuring the survival of a significant portion of the population.

The acoustic environment created by cicadas also influences the behavior of other animals. Birds and mammals may alter their foraging strategies during cicada emergences, while other insects may adjust their own calls to avoid overlap with cicada sounds.

Cicadas in Different Cultures

Cicadas have long held a place in human culture, symbolizing various themes and concepts across different societies. In ancient China, cicadas were associated with rebirth and immortality, often depicted in art and literature as symbols of renewal. The cicada's life cycle, with its long period of underground development followed by a brief, vibrant adult phase, mirrors the cycle of life and death.

In Japan, cicadas are a quintessential sound of summer and are often featured in haiku and other forms of poetry. Their song is seen as a reminder of the fleeting nature of life, encouraging people to appreciate the present moment.

In Western cultures, cicadas are often associated with nostalgia and the passage of time, evoking memories of warm summer days. Their distinctive sound is frequently used in films and music to create a sense of atmosphere and place.

Ecological Role of Cicada Sounds

Cicada sounds have a profound impact on their ecosystems, influencing both biotic and abiotic components. The mass emergence of cicadas, accompanied by their loud calls, can alter the behavior of predators and prey.

These emergences can provide a temporary food source for birds, mammals, and other insects, leading to shifts in local food webs. The sheer volume of cicada calls can also mask the sounds of other animals, potentially affecting communication and mating behaviors in other species.

Furthermore, the presence of cicadas can influence plant communities. As cicadas feed on tree sap, they can affect the health and growth of their host plants. The nutrient-rich waste produced by cicadas, known as frass, can also contribute to soil fertility and influence plant growth.

Cicada Sounds and Human Perception

The sound of cicadas is often perceived differently by humans, depending on cultural background, personal experience, and environmental context. For some, the sound is a nostalgic reminder of childhood summers, while for others, it may be an annoying or disruptive noise.

Studies have shown that people living in areas with regular cicada emergences tend to develop a tolerance or even appreciation for the sound. In contrast, those unfamiliar with cicadas may find the sound overwhelming or unsettling.

Cicada sounds have also been studied for their potential therapeutic effects. The rhythmic and repetitive nature of cicada calls is believed to have a calming effect on some individuals, similar to the sound of ocean waves or rainfall.

What Do Cicadas Sound Like When in Distress?

In addition to their mating calls, cicadas produce distinct sounds when threatened or in distress. These distress calls are typically shorter and more abrupt than their mating songs and serve as a warning to potential predators.

When captured or handled, cicadas may emit a loud, high-pitched screech, intended to startle and deter predators. This sound is produced by rapidly vibrating the tymbals, similar to their mating calls but with a different rhythm and intensity.

These distress calls can also serve as an alarm signal to other cicadas in the vicinity, alerting them to the presence of danger and potentially triggering a synchronized response.

Comparing Cicada Sounds to Other Insects

Cicada sounds are often compared to those of other singing insects, such as crickets and katydids. While all these insects produce sound using similar mechanisms, there are distinct differences in their calls.

• Crickets: Known for their rhythmic chirping, produced by rubbing their wings together in a process called stridulation.
• Katydids: Produce a series of clicks or buzzes by rubbing their wings together, often at night.
• Grasshoppers: Generate sound by rubbing their legs against their wings, creating a series of raspy notes.

In contrast, cicadas produce sound using tymbals and are capable of producing much louder and more complex calls. This ability sets them apart from other singing insects and contributes to their unique place in the natural soundscape.

Can Cicada Sounds Affect Humans?

The impact of cicada sounds on humans can vary widely, depending on individual sensitivity and environmental context. While some people find the sound soothing or nostalgic, others may experience stress or annoyance, particularly during mass emergences.

In areas with large cicada populations, the sheer volume of their calls can reach levels that may affect human activities. Outdoor events, conversations, and even sleep may be disrupted by the incessant buzzing of cicadas.

However, there are also potential benefits to cicada sounds. The rhythmic and repetitive nature of their calls may have a calming effect on some individuals, similar to white noise.
