Periodical cicada Brood XIV (14) will emerge in 2025 in Thirteen States

Filed under: Brood XIV | Magicicada | Periodical — Dan @ 8:53 am

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

What, when, where:

What:

  • Millions of these:
    Adult, Nymph Molting
  • Cicada insects 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 that arrive annually.

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

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

Where:

  • Georgia counties: Fannin, Lumpkin, Rabun, Union
  • Indiana counties: Crawford, Harrison, Perry
  • Kentucky counties: Adairville, Anderson, Barren, Bath, Bell, Bourbon, Boyd, Bracken, Campbell, Carter, Clinton, Edmonson, Fayette, Franklin, Floyd, Gallatin, Grant, Hardin, Harrison, Henderson, LaRue, Laurel, Leslie, Madison, Montgomery, Nelson, Nicholas, Pendleton, Pulaski, Rowan, Scott, Shelby, Whitley

Brood XXIII Cicada Stragglers are emerging!

Filed under: Brood XXIII | Chris Simon | Magicicada | Periodical Stragglers — Dan @ 6:24 pm

BROODXXIII

One phenomenal behavior of Magicicada periodical cicadas is they “straggle”, meaning they emerge earlier or later than the year they are expected. Typically they emerge 1 or 4 years before they’re supposed to emerge.

Brood XXIII is expected to emerge in four years in 2028, but enough are emerging in 2024 for cicada researchers like Chris Simon to take notice! She let us know about the stragglers on May 8th.

Brood XXIII is found in Arkansas, Illinois, Indiana, Kentucky, Louisiana, Mississippi, and Tennessee. This is not a perfect map (it overlaps with Brood XIX), but XXIII cicadas will show up in that area.

Arkansas: Bayou Deview Wildlife Management Area, Poinsett County, Devalls Bluff, Harrisburg, Holland Bottoms, Jacksonville, Jonesboro, Knox Co., Lake Hogue, Lake Poinsett State Park, Little Rock, and Wynne.

Illinois: Anna, Carbondale, Carterville, Chester, Clinton Lake, Marissa and Robinson.

Indiana: Harmonie State Park, Hymera, Leanne, Richland, Sullivan And Posey Counties.

Kentucky: Benton, Calvert City, Gilbertsville, Henry County, Murray, and Paducah.

Louisiana: Bastrop, Choudrant, Grayson and West Monroe.

Mississippi: Alva, Arlington, Booneville, Brandon, Clinton, Corinth, Desoto County, Florence, French Camp, Hernando, Holcomb, Houlka, Jackson, New Albany, Oxford, Potts Camp, Silver Creek, Tishomingo, and Water Valley.

Tennessee: Atoka, Benton, Cordova, Henry County, Huntingdon, Jackson, Lavinia, Leach, Lexington, McNeary County, Memphis, Paris, Savannah, and Speedwell.

Here’s a blue overlay of there Brood XXIII emerges from the UCONN map on the iNaturalist data (as of May 5th):

Surrounding the blue area on the west and east is Brood XIX and north will be Brood XIII.

Fall Magicicada cassini straggler found in Park Ridge, IL

Filed under: Brood XIII | Magicicada | Periodical Stragglers — Tags: — Dan @ 10:22 am

Mary Rotter Fullerton found, or rather heard and recorded, a Brood XIII Magicicada cassini straggler on October 2nd, 2023, in Park Ridge, Illinois! This cicada emerged 7 months early!

Listen to the edited file (volume increased, background noise removed):

There are squirrel sounds in the mix as well.

Mary says:

Very cool, I have never heard one in fall. It was in a 50-year old maple tree that hosted many stragglers (early Brood XIII?) this past spring of 2023. Park Ridge, IL.

Spectrogram:
Mary Rotter Fullerton

David Marshall of InsectSingers.com confirmed that this is indeed a Magicicada cassini.

David says:

Yes to me that’s unquestionably a set of cassini calls. There are some literature records of autumn Magicicada, sometimes with speculation that it’s related to sudden late-season warmups.

It looks like there’s been quite a few fall stragglers, according to the Magicicada Straggler project on iNaturalist.
