Brood XIV cicadas, emerging every 17 years, are set to appear in parts of the eastern U.S., including New York and Tennessee, starting mid-May. These insects, crucial for forest ecosystems, surface in massive numbers when soil warms to about 64°F. They do not bite or sting but are known for their loud buzzing sounds. Their emergence this year marks their return since 2008, with the next appearance slated for 2042.
