Updated for June 7th!

Here’s a map of 2023 Magicicada straggler sightings from 2023 Magicicada stragglers iNaturalist project and the Cicada Safari app. Dr. Gene Kritsky compiled the map.

It looks like there are plenty of stragglers from these broods:

Brood XIII and Brood XIX Magicicada will both emerge in 2024

Filed under: Brood XIII | Brood XIX | Periodical — Dan @ 9:42 am

News! A Brood XIX straggler has emerged in Georgia! More stragglers have been sighted in Hartselle AL, Pittsboro, NC, Chattanooga, TN, Asheboro, NC, and Chapel Hill, NC.

2024 will be a “magical” year for cicada fans because the periodical cicada broods XIII and XIX will emerge in 2024. These broods co-emerge every 221 years (13 X 17). The last time they co-emerged was in 1803, the same year as the Louisiana Purchase (the same year the U.S. got Brood XIX states Louisiana, Arkansas, Iowa, Kansas, Missouri, and Oklahoma). Coincidence? Perhaps.

Thomas Jefferson thinking of the cicadas he just bought.

Brood XIII (13) has a 17-year lifecycle and is found in the states of IA, IL, IN, MI, and WI. This brood features the species Magicicada septendecim, Magicicada cassini, and Magicicada septendecula.

People (cicada tourists) have begun to ask “Where is the best place to see Brood XIII in 2024?”. I can recommend the Ryerson Conservation Area in Deerfield, IL. See photos and videos from my trip there in 2007. Illinois has both Brood XIII and Brood XIX, and all 7 Magicicada species. So you could spend a week in southern Illinois for Brood XIX and then travel north to Deerfield for Brood XIII.

Brood XIX (19) has a 13-year lifecycle and is found in the states of AL, AR, GA, IA, IL, IN, KS, KY, LA, MD, MO, MS, NC, OK, SC, TN, and VA. This brood is also known as the Great Southern Brood and features the species Magicicada tredecim, Magicicada neotredecim, Magicicada tredecassini, and Magicicada tredecula.

Do these broods overlap? If they do, it’s in the Springfield, Illinois area. Springfield is a good place for your cicada sightseeing “basecamp”. Take a look at these maps on the UCONN Cicadas website: Brood XIX and Brood XIII.

Your next chance to see and hear two broods co-emerge will be in 2037 when Brood XIX and Brood IX (9) emerge.

Periodical cicada nymphs emerging at night

Filed under: Brood XIII | Magicicada | Molting | Nymphs | Periodical — Tags: — Dan @ 5:29 am

One of the most fun periodical cicada experiences is watching thousands of nymphs emerge from the ground at night, crawl to the nearest vertical surface (hopefully a tree) and begin to molt.

This is a video by Roy Troutman from 2007 of the Brood XIII emergence, specifically in Ryerson Woods in Illinois:

Chicago Area Periodical Cicada Emergences in 2020

Filed under: Accelerations | Brood XIII | Magicicada | Periodical Stragglers | United States — Dan @ 10:04 am

Many periodical cicadas emerged four years early in the Chicago area in 2020. These cicadas belong to the Brood XIII (13) which is set to emerge in 2024, and last emerged in 2007. Periodical cicadas often emerge in years proceeding or following the year their brood is expected to emerge. This phenomenon is called straggling. Most of the time these “stragglers” emerge in small numbers and are quickly eaten by predators, and do not go on to sing, chorus (synchronized singing for the purpose of attracting females), mate, and lay eggs. Sometimes they emerge in numbers large enough to survive, chorus, and reproduce — this seems to have happened in the Chicago area in 2020. It is thought this is how new broods formed over the millennia — cicadas emerge 4 or 1 year early in significant numbers and form a new brood. When enough stragglers emerge to successfully reproduce it is called an acceleration.

So, is a new brood forming around Chicago? Is this due to climate change or localized “heat islands”? Will the progeny of these stragglers emerge in 13, 17 or 21 years? Lots of questions — but we’ll need to wait quite some time to answer them.

There is a precedence for Brood XIII cicadas straggling in the Chicago area:

In 1969 massive numbers of periodical cicadas emerged in the Chicago suburbs 1 (Williams, K.S. & Simon, C. 1995).

In 1986, another 4-year acceleration was observed in the Chicago area by Monte Lloyd 1.

In 2003, many people left observations on our forums. Observations were made in Glenview, Flossmoor, Riverside, Downers Grove, Homewood, Westmont, Oak Park, and Hinsdale. Here are some examples:

Magicicada emerging this evening

Date: Wednesday, Jun/4/2003

Message: As I went for a walk this evening I noticed quite a few periodic cicadas emerging in the grass, crawling on the sidewalks and on the trunks of trees. This is not our year for the 17-year brood. We should not have them until 2007. Has anyone else in the Chicago area seen these cicadas? — Sue, Flossmoor, IL

Cicada singing

Date: Monday, Jun/9/2003

Message: I heard the cicadas singing for the first time this morning after my walk. Now that I have my doors open I can hear them on and off. — Sue, Flossmoor, IL

In 2020 many people left comments on the Brood XIII page, emailed us (thanks Neil) and left sightings via the Cicada Safari app.

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

Filed under: Brood XIII | Magicicada | Periodical — Dan @ 1:02 am

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.

What, when, where, and why:

What:

Millions of these:
Adult, Nymph, Molting Cicada

  • 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.

  • Indiana counties: LaPorte, Porter, Lake.
  • Michigan: According to Cicadas @ UCONN (formerly Magicicada.org), Magicicada have been found along the border of Michigan and Indiana.

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.
