Brood XIII (13) will emerge in 2024 in Illinois, Iowa, Wisconsin and Indiana

Some Brood XIII “stragglers” emerged early in 2020. If you see a cicada and want to report it, the Cicada Safari App is available for Android and Apple devices 📱.

A particularly large amount of Brood XIII cicadas are emerging early this year. Here’s a news article and a note from the Illinois Extension. Thanks Neil for the links.

One thing that is important to determine is whether any of the off-schedule populations (especially the 4-year early and 4-year late ones) are large enough to persist and lay eggs. The big question is will they establish a new population? Please send photos of cicadas laying eggs. And if egg laying is extensive enough to damage branches, please send photos of that as well!

Some Brood XIII cicadas are emerging 4 years early, particularly in the Chicago area in 2020. Blue in the map below:

Periodical cicada Brood XIII (13) will emerge in the spring of 2024 in Iowa, Wisconsin, Illinois, Indiana, and possibly Michigan. The last time this brood emerged was in 2007.

Special note: Brood XIX (19) will also emerge in 2024.

  • 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.

More Location Tips:

Why: Why do they stay underground for 17-years? The prevailing research suggests they’ve evolved a long, 17-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.
