Introduction
Have you noticed a strange buzzing sound filling the air in Las Vegas lately? It’s not the hum of the Strip, the whir of a slot machine, or even the drone of a distant airplane. It’s the song of the cicadas, and they’re making their presence known. These fascinating insects, often mistaken for locusts, are a natural part of the desert ecosystem, and understanding them can help you appreciate this temporary auditory phenomenon. This article will provide you with essential information about the cicadas buzzing around Las Vegas, explaining why they’re here, what to expect, and how to coexist with these noisy neighbors.
Cicadas in the Las Vegas Area: Species and Identification
The Las Vegas area, despite its reputation as a concrete jungle, is surrounded by a thriving desert environment that supports a surprising diversity of life, including several species of cicadas. While a full taxonomic survey is lacking, the cicadas most commonly encountered belong to the Diceroprocta genus. The Diceroprocta apache cicada, sometimes called the Apache cicada, is a likely candidate. These cicadas are well adapted to the arid climate.
Identifying these cicadas can be straightforward once you know what to look for. Typically, they are medium to large insects, ranging in size from one to two inches in length. Their bodies are robust and colored in shades of brown, black, and green, providing excellent camouflage against tree bark and desert vegetation. A key identifying feature is their prominent, bulging eyes, often reddish or brownish in color. Their wings are transparent with intricate vein patterns that shimmer in the sunlight.
While the Diceroprocta apache is a likely species, other closely related cicadas might also be present. Look for subtle differences in size, color patterns, and especially the sounds they produce. Each species has a unique call, a sort of insect serenade that distinguishes them from one another. To further aid in identification, consider using online resources with pictures and sound samples to compare with the cicadas you encounter in your neighborhood.
Cicadas are most likely to be found where there are trees and shrubs. Parks, gardens, residential areas with mature landscaping, and especially the edges of the desert where vegetation is denser are prime cicada habitats. While they can tolerate the heat, they prefer areas where they can find shade and moisture. Elevation may also play a role, with certain species favoring slightly higher altitudes where temperatures are a bit cooler.
It is important to note that cicadas are not a novel occurrence in Las Vegas, and while sightings may appear increased some years, these insects have always been present in the desert landscape. Enhanced awareness and reporting may contribute to the impression of heightened numbers, but cicadas are a constant feature in the Nevada environment. Environmental factors, such as higher than average rainfall during the nymphs’ development or increased vegetation, can influence their numbers and emergence patterns.
The Cicada Life Cycle: A Tale of Underground Waiting
The cicada life cycle is a marvel of nature, characterized by an extended period of development underground followed by a brief, intense period of activity above ground. It all starts with the adult female cicada, who lays her eggs in the twigs and branches of trees using a specialized ovipositor. After hatching, the tiny nymphs drop to the ground and burrow into the soil.
The nymph stage is where the real magic happens. These underground dwellers spend years, even decades in the case of periodical cicadas found elsewhere in the country, feeding on the sap from plant roots. They molt several times as they grow, gradually increasing in size. In the Las Vegas area, the lifecycle is expected to be on average between two and five years due to annual cicada variations.
When the time is right, triggered by factors such as soil temperature and moisture levels, the mature nymphs emerge from the ground. They typically do this at night to avoid predators and the intense desert heat. They then climb onto trees, shrubs, or even buildings and undergo their final molt, transforming into adult cicadas.
The adult stage is relatively short, lasting only a few weeks. Their primary focus is on reproduction. Males attract females with their loud calls, and after mating, the females lay their eggs, starting the cycle anew. Adult cicadas do not feed extensively, relying on energy reserves accumulated during their nymph stage.
The harsh desert environment significantly impacts the cicada life cycle. Water availability is crucial, as the nymphs depend on plant roots for their source of hydration. Periods of drought can stress the nymphs, potentially delaying their development or reducing their survival rates. Temperature extremes also pose a challenge, and cicadas have evolved adaptations to cope with the heat, such as burrowing deeper into the soil and emerging during cooler periods.
The Cicada Sound: Why So Loud?
The characteristic buzzing or singing sound of cicadas is one of the most distinctive features of summer in many parts of the world, including Las Vegas. But how do these relatively small insects create such a loud and pervasive noise? The secret lies in their unique anatomy.
Male cicadas possess specialized structures called tymbals, located on the sides of their abdomen. These are essentially ribbed, drum-like membranes that they can rapidly buckle and unbuckle using muscles. This rapid vibration creates a series of clicks, which are amplified by the hollow abdomen, acting as a resonating chamber.
The purpose of this loud sound is to attract mates. Male cicadas are essentially broadcasting their availability to females, hoping to be the chosen one. The loudness of the sound is necessary because cicadas need to reach potential mates over long distances, especially in open desert environments. The chorus of many males singing together creates a deafening cacophony that can be heard for miles.
Different species of cicadas produce different sounds. The frequency, rhythm, and intensity of the call can vary, allowing females to distinguish between potential mates of their own species. Some species produce a continuous buzzing sound, while others create clicks, trills, or even musical melodies. Local expertise could potentially distinguish the different sounds of species of cicadas in the area.
Generally, only male cicadas produce the loud mating calls. Females are typically silent, although they may produce soft clicking sounds in response to male calls. The cicada song has been part of human culture for centuries, appearing in literature, music, and folklore. In some cultures, it symbolizes rebirth, resilience, and the fleeting nature of life.
Cicadas: Harmless or Harmful? (Impact on Las Vegas)
Cicadas are often perceived as pests due to their loud noise and sheer numbers, but their ecological role is generally positive. They play several important roles in the desert ecosystem, contributing to soil aeration and as a food source for other animals. However, there are some potential negative impacts to consider.
Cicada nymphs, as they burrow and feed on plant roots, help aerate the soil, improving its structure and drainage. When they emerge and die, their bodies decompose, releasing nutrients back into the soil, enriching it for future generations of plants. The mass emergence of cicadas provides a feast for birds, reptiles, mammals, and even other insects.
While the noise can be a nuisance, cicadas rarely cause significant damage to plants. The egg-laying process can cause minor damage to twigs and branches, but this is usually minimal and does not harm mature trees. They are not known to bite or sting humans and pose no direct threat to pets.
While cicadas are native to the region and not an invasive species, their sheer numbers can be overwhelming, especially during peak emergence years. However, this is a temporary phenomenon, and the benefits they provide to the ecosystem outweigh any minor inconveniences.
Dealing with Cicadas in Las Vegas: Coexistence is Key
Generally, intervention is not needed for cicadas. Efforts to control cicadas are often ineffective and can be harmful to other wildlife. The best approach is to simply coexist with these fascinating insects and appreciate their temporary presence.
For young or vulnerable trees, consider using netting to protect them from egg-laying damage. Ensure that plants are well-watered, as healthy plants are more resilient to any potential stress caused by cicadas.
Avoid using pesticides to control cicadas. These chemicals can harm beneficial insects, birds, and other animals, disrupting the delicate balance of the ecosystem. Chemical controls are unlikely to be effective given the sheer number of cicadas and their widespread distribution.
The best way to deal with cicadas in Las Vegas is to embrace the natural phenomenon. Enjoy the unique soundscape they create, and appreciate the opportunity to witness this remarkable event. It’s a reminder that even in the heart of a bustling city, nature still thrives.
