News! a Brood XIX straggler has emerged in Georgia!

Periodical cicada Brood XIX (19) will emerge in the spring of 2024 in Alabama, Arkansas, Georgia, Illinois, Indiana, Kansas, Kentucky, Louisiana, Missouri, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, and Virginia. The last time this brood emerged was in 2011.

Special note: Brood XIII will also emerge in 2024.

What, when, where, and why:


Millions of these:
Adult, Nymph, Molting Cicada

  • Cicada insects with a 13-year life cycle.
  • Some people call them “locusts” but they’re really cicadas.
  • Which species: All four 13-year species:
    • Magicicada neotredecim Marshall and Cooley, 2000. Range includes: AR, IL, IN, KS, KY MO, & OK.
    • Magicicada tredecim (Walsh and Riley, 1868). Range includes: AL, AR, GA, IL, IN, KS, KY, LA, MD, MO, MS, NC, OK, SC, TN & VA
    • Magicicada tredecassini Alexander and Moore, 1962
    • Magicicada tredecula Alexander and Moore, 1962
  • NOT the green ones that arrive annually.

Brood XIX has a 13-year cycle. It is interesting because it features both Magicicada neotredecim and Magicicada tredecim. These cicadas are very similar in song and appearance, but in areas where they overlap, Magicicada neotredecim alters its song to a higher pitch, which allows female cicadas to determine the species of their prospective mates. Visit Cicadas @ UCONN (formerly for more info on this behavior.

M. tredecim also have more orange on their abdomen than M. neotredecim.
Compare 13 year decims

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.

More Location Tips:

Why: Why do they stay underground for 13-years? The prevailing research suggests they’ve evolved a long, 13-year lifecycle to avoid predators that can sync up with their lifecycle & emergence. Why are there so many?! Research suggests that their huge numbers allow them to overwhelm predators, so enough of them will live on to breed and perpetuate the brood.

    Hi! Didn’t see Greenwood, SC on the list for Brood XIX but we absolutely got them in 2011! <3 Can't wait to see them again.

    1. Camilla MCDevitt says:

      They were definitely in Greenwood. Unlike you, I am not looking forward to their reemergence next year. They were everywhere and the noise was incredible. Sounded like car alarms going off nonstop.

  7. Katie Fobert says:

    They are emerging by the hundreds today in Channahon IL. 60410. I wasn’t expecting any this year , but I wasn’t really keeping track. We are on the edge of will and grundy county

  8. David Ledgerwood says:

    We have had hundreds of these little creatures come up around our front porch in the past week or so. I have had to sweep them up and gather them with a shovel just to clear a path to get out of the house without stepping on them. Those that are not in the way we leave alone. We have 2 puppies who have also been helping :-/

    1. Stav C says:

      Hey David, can you share approximately where you’re located? Are there any good camping places? I really want to go camp somewhere this weekend where I can see the brood emerging :).

      @Jon, thanks. I’ve added that paragraph to the page.
