Periodical cicada Brood XIV (14) will emerge in the spring of 2025 in Georgia, Kentucky, Indiana, Massachusetts, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia. The last time this brood emerged was in 2008. Special note: removing Maryland from the list.

What:

• Millions of these Magicicada cicada insects:
  
• Cicadas with a 17-year life cycle.
• Some people call them “locusts” but they’re really cicadas.
• Which species: All three 17-year species, Magicicada septendecim, Magicicada cassini and Magicicada septendecula. How to tell the difference between the species.
• NOT the green ones (Neotibicen) that arrive annually.

When:

Usually beginning in mid-May and ending in late June. These cicadas emerge approximately when the soil 8″ beneath the ground reaches approximately 64 degrees Fahrenheit. A warm rain will often trigger an emergence.

Other tips: these cicadas will emerge after the trees have grown leaves, and, according to my own observation, around the same time Iris flowers bloom.

Where:

City data comes from May 2008 and June 2008 blog comments. County locations are historical and may no-longer be accurate.

• Georgia counties: Fannin, Lumpkin, Rabun, Union. We’re talking the northeastern part of Georgia, within the Blue Ridge Mountains region.

We’re talking most of Kentucky east of U.S. Route 41, with major hot-spots along the Ohio river.
• Kentucky cities: Adairville, Bowling Green, Corbin, Flemingsburg, Frankfort, Greensburg, Hazard, Radcliff, Richmond

• North Carolina counties: Buncombe, Burke, Caldwell, Catawba, Henderson, McDowell, Mitchell, Wilkes. We’re talking western North Carolina, particularly areas heavily impacted by Hurricane Helene.
