The year 2011 brought an unforgettable spectacle to Nashville, Tennessee—an event that was both enchanting and eerie: the arrival of the cicadas. This natural phenomenon turned the city into a buzzing hub, literally, as millions of cicadas emerged from their underground lairs after spending 13 years in the soil. Known as Brood XIX, this swarm of periodical cicadas captivated residents, scientists, and nature enthusiasts alike, creating an auditory and visual experience that was impossible to ignore.
Cicadas are not just your average backyard insects. These enigmatic creatures follow a unique life cycle, surfacing in massive numbers only once every 13 or 17 years, depending on the brood. Their synchronized emergence in Nashville during 2011 was a marvel of nature, showcasing the incredible rhythms of the natural world. The event also drew significant attention from media outlets, biologists, and curious onlookers, all eager to witness this rare occurrence firsthand.
Beyond the fascination, the cicadas' arrival also brought challenges and questions. From understanding their purpose in the ecosystem to dealing with the deafening sound of their mating calls, the city had to adapt quickly. Whether it was the economic impact on local businesses, the scientific studies conducted during their presence, or the cultural imprint they left behind, the cicadas of Nashville in 2011 were more than just a natural wonder—they were a phenomenon that left a lasting impression on the Music City.

Biology of Cicadas
Cicadas are fascinating insects that belong to the order Hemiptera and the family Cicadidae. They are known for their large size, transparent wings, and loud mating calls. Unlike other insects, cicadas are harmless to humans, lacking the ability to sting or bite. Their life cycle, behaviors, and ecological roles make them an important subject of study in entomology.
Physical Characteristics
Cicadas are easily recognizable by their robust bodies, bulbous eyes, and membranous wings. Adult cicadas are typically between 1 and 2 inches long, with colors ranging from black and brown to green and orange. Their prominent eyes are often red, and their wings feature distinctive veins that add to their unique appearance.
Diet and Feeding Habits
Cicadas primarily feed on xylem sap from trees and plants. Using their specialized mouthparts, they pierce the bark or stems to access this nutrient-rich fluid. While their feeding habits are not harmful to mature plants, they can sometimes cause minor damage to young trees.
Natural Predators
Cicadas have several natural predators, including birds, spiders, and small mammals. Interestingly, their synchronized emergence in large numbers is a survival strategy known as "predator satiation." By overwhelming predators with sheer abundance, a significant portion of the cicada population survives to reproduce.
Life Cycle and Brood XIX
The life cycle of cicadas is one of the most intriguing aspects of their biology. Periodical cicadas like those of Brood XIX follow a 13- or 17-year cycle, spending the majority of their lives underground as nymphs. This prolonged development is a unique adaptation that helps them avoid predators and environmental challenges.
The Nymph Stage
During their time underground, cicada nymphs feed on the sap of tree roots. They remain hidden and grow slowly, molting multiple times before they are ready to emerge. This stage can last for up to 13 years, as was the case with Brood XIX.

The Emergence
When the soil temperature reaches approximately 64°F, the nymphs emerge en masse. This synchronized event typically occurs in late spring and is triggered by environmental cues. The cicadas then climb trees and other structures to molt into their adult form.
Reproduction and Death
Once they become adults, cicadas have a short lifespan of just a few weeks. During this time, males produce loud mating calls to attract females. After mating, females lay eggs in tree branches, and the cycle begins anew. The adults then die, leaving behind their exoskeletons as a reminder of their brief but impactful presence.
Why Cicadas Emerged in Nashville
Nashville's climate and geography played a crucial role in the emergence of Brood XIX in 2011. The region's temperate conditions and abundance of trees provided an ideal habitat for cicadas, ensuring the success of their life cycle. Additionally, the timing of their emergence aligned perfectly with the seasonal changes in the area.

Frequently Asked Questions
1. What are cicadas?
Cicadas are insects known for their loud mating calls and synchronized emergences. They belong to the order Hemiptera and are harmless to humans.
2. Why do cicadas emerge only every 13 or 17 years?
Their long life cycles are an evolutionary adaptation to avoid predators and environmental challenges. This phenomenon is unique to periodical cicadas.
3. How loud were the cicadas in Nashville during 2011?
The cicadas' mating calls reached up to 90 decibels, comparable to the noise level of a lawnmower or motorcycle.
4. Did cicadas cause any damage to Nashville's trees?
While cicadas can cause minor damage to young trees by laying eggs in branches, mature trees typically remain unaffected.
5. How did Nashville residents cope with the cicada emergence?
Residents adapted by using earplugs, covering outdoor equipment, and educating themselves about the cicadas' ecological importance.
6. When will cicadas return to Nashville?
Brood XIX is expected to return in 2024, as it follows a 13-year cycle. Preparations are already underway to study and manage their emergence.
