The Return of the Cicadas: Brood XIX Emerges in Tennessee

As temperatures rise and spring settles in, parts of Tennessee are experiencing the emergence of Brood XIX cicadas after 13 years of dormancy. While the brood wasn't expected to surface until mid-May, sightings have already been reported in Middle Tennessee, signaling the beginning of their noisy presence. What is Brood XIX?

Brood XIX, also known as the 13-year cicadas, is making its appearance in Tennessee after more than a decade underground. Unlike the more well-known 17-year periodical cicadas, Brood XIX emerges every 13 years, and this year, their emergence is limited to about 18 counties, mainly in Middle and East Tennessee. Where Can You Spot Them?

Reports of Brood XIX sightings have come in from areas around Nashville and Middle Tennessee. According to Cicadamania.com, the following Tennessee counties are expected to see cicadas this year: Blount, Cheatham, Clay, Davidson, Grundy, Hamilton, Jackson, Loudon, Macon, Marion, McMinn, Meigs, Putnam, Rutherford, Sequatchie, Smith, Stewart, and Sumner. How Long Will They Stick Around? Brood XIX cicadas are expected to be active until about mid-June as they emerge to find mates before returning to hibernation underground.

Cicadas Across the United States Brood XIX is not the only cicada brood emerging this year. They are part of a combined 17-state emergence across the Southeast and Midwest, with an overlap in parts of Illinois and Iowa. The emergence of cicadas is dependent on soil temperatures reaching 64 degrees Fahrenheit at a depth of eight inches. Noise Levels and What to Expect As the cicadas emerge, their distinctive mating call fills the air. While Tennessee is accustomed to the sound of annual cicadas during the summer months, the arrival of Brood XIX brings a more intense chorus. The noise level can be quite high, but the duration and intensity can vary depending on the location and weather conditions. Where Else Are Cicadas Emerging? Southern states, with their warmer climates, are more likely to see the early emergence of cicadas. Reports of cicada sightings have also come in from places like South Carolina and parts of Arkansas. Conclusion The emergence of Brood XIX cicadas in Tennessee marks a natural phenomenon that occurs only once every 13 years. While their presence may be loud and overwhelming at times, it's a reminder of the fascinating cycles of nature that continue to amaze us. So, keep an eye out for these noisy insects and marvel at the wonders of the natural world.
