17 & 13 Year Periodical Cicadas

🛑 This page is strictly for Magicicada periodical cicadas, aka 17 & 13-year cicadas, aka "locusts" (read why they’re called locusts).
This does not cover annual cicada species in North America and other parts of the world.

📅 Brood IX (Nine) emerged in 2020 in North Carolina, Virginia and West Virginia. “Stragglers” from other broods also emerged in limited numbers: Brood X (1 year early), Brood XIX (4 years early) and Brood XIII (4 years early). Here’s a map where they emerged:

When will they emerge?

📅 🌡️ Generally speaking, these cicadas will begin to emerge when the soil 8″ beneath the ground reaches 64 degrees Fahrenheit (Heath, 1968). A nice, warm rain will often trigger an emergence. They typically emerge in May but have been known to emerge in late April or early June. It all depends on the weather.

What should you look for before they emerge?

Chimneys / Turrets

Look for cicada chimneys a.k.a. turrets. These are structures cicadas build out of the soil, positioned above the hole where they will emerge.

Chimney

Holes

Look for holes the diameter of an adult’s finger near the root system of a tree. These are sure signs that cicadas will emerge in the area.

Holes

Cicadas Under Stones & Slates

You might discover some cicada nymphs while turning over stones or when performing landscaping chores.

Cicada tunneling under slate

What do they look like when they emerge:

Here is a great video of Magicicada nymphs once they have emerged from the ground:


Nymph

This is a recently emerged nymph crawling up a tree. Note that its eyes are red.

Nymph

Once cicadas nymphs have emerged from the ground, they will try to find a tree (or similar vertical surface), and then begin the process of shedding their old nymph skins (ecdysis), expanding their wings, and changing to their adult coloring. Watch this amazing transformation.

How to tell the difference between the seven Magicicada species:

The first way is based on the Brood. Take a look at the Brood chart above, and see which species appear with the Brood.

There are 3 basic types of Magicicada: “‘Decims”, “‘Cassini” and “‘Deculas”.

“Decims” aka Pharaoh Cicadas

There are three species in this category:

  1. Magicicada septendecim (Linnaeus, 1758). 17-year life cycle. Broods: I-X, XIII, XIV.
  2. Magicicada neotredecim Marshall and Cooley 2000. 13-year life cycle. Broods: XIX, XXIII.
  3. Magicicada tredecim (Walsh and Riley, 1868). 13-year life cycle. Brood: XIX, XXII, XXIII.

Their songs are very similar, however, when M. neotredecim & M. tredecim emerge in the same location, M. neotredecim’s song takes a higher pitch. Sounds like “Pharaoh, Pharaoh!”.

Visual Appearance:

M. septendecim
Male on left; Female on right.

M. neotredecim & M. septendecim have broad orange stripes with more orange than black on their abdomens.

M. tredecim
M. tredecim, by comparison, have almost entirely orange abdomens.

eye to wing
M. septendecim also have an area of orange coloring between the eye and the wing (pronotal extension).

“Cassini” aka Dwarf Cicadas

There are two species in this category:

  1. Magicicada cassini (Fisher, 1851). 17-year life cycle. Broods: I-V, VIII-X, XIII, XIV.
  2. Magicicada tredecassini Alexander and Moore, 1962. 13-year life cycle. Broods: XIX, XXII, XXII.

Their songs are essentially identical:

M. cassini Call and Court:

Note how it makes a quick burst of sound, followed by some rapid clicks.

Visual Appearance:

M. cassini
Female on left; Male on right.
M. tredecassin & M. cassini have black abdomens with virtually no orange at all. Orange stripes are possible in the mid-west (important to note for Brood IV).

“Decula”

There are two species in this category:

  1. Magicicada septendecula Alexander and Moore, 1962. 17-year life cycle. Broods: I-VI, VIII-X, XIII, XIV.
  2. Magicicada tredecula Alexander and Moore, 1962. 13-year life cycle. Broods: XIX, XXII, XXIII.

Their songs are essentially identical:

M. tredecula Call:

Note the “tick, tick, tick” rhythm of the call.

Visual Appearance:

M. septendecula
Female on left; Male on right.
M. septendecula & M. tredecula have stripes that feature more black than orange. Otherwise, they’re very similar to M. cassini.

How to figure out if they’re coming to your town?

  1. Verify that they’re coming to your state. Check the Magicicada Brood Chart on this page.
  2. Check Cicada Brood Maps linked from this page to see if they’re coming to your general area.
  3. Check to see if they’re coming to your neighborhood. Good sources include:
    1. Check the Cicada Central Magicicada Database to see the counties where cicadas have appeared in the past.
    2. Ask someone who lived there 17 (or 13) years before.
    3. Old timers (hint: old timers usually call them locusts).
    4. Check your local Library for old newspaper articles.
    5. Check with a local college: contact the entomology, forestry, or agriculture-related departments.
    6. Your local national, state, county and town parks department (parks and rec). Some county parks departments plan events around cicada emergences.
  4. When will they emerge?
    1. They will emerge sometime in the Spring, for sure.
    2. They typically emerge once the soil 8 inches (20 cm) below the surface gets to 64 degrees Fahrenheit (18 degrees Celcius). At that temperature, they will start digging their tunnels to the surface. After a couple of days with above-ground temperatures near the 80’s F, and after a good rain, they will definitely emerge. Read this paper for more info: Thermal Synchronization of Emergence in Periodical “17-year” Cicadas (Homoptera, Cicadidae, Magicicada) by James Edward Heath, American Midland Naturalist, Vol. 80, No. 2. (Oct., 1968), pp. 440-448.
    3. Cicadas in sunny areas of your yard will emerge before cicadas in shady areas.
    4. Cicadas in the southern-most states will emerge before cicadas in northern states.
    5. You can try the Cicada Emergence Formula as well.
  5. If you don’t want them do damage your young / ornamental trees
    1. Spray them off with a garden hose.
    2. Foil around the trunk (to keep them from crawling up) (thanks Deborah).
    3. Insect barrier tape.
    4. Netting placed around & over the tree. “Insect barrier netting”. “Fruit tree covers”.
    5. Bagpipes (no joke, it worked at my friend’s wedding).
    6. Don’t use pesticide – we like all insects (especially pollinating bees).
  6. Are you scared of insects?
    • Unlike some other insects & arthropods. cicadas are not poisonous or venomous.
    • Try a hat, an umbrella, a bee-keepers’ outfit, a suit of armor…
  7. They’re coming, and they’re going to ruin my wedding!

Questions about the Brood Chart

Question: Why do I have cicadas in my neighborhood, but your chart indicates that I shouldn’t?

Answer: Some possibilities: 1) they are stragglers, periodical cicadas that emerge too soon or late, 2) they are not periodical cicadas, but are a different North American species, 3) you live on a continent other than North America, in which case, try one of these pages, or 4) SURPRISE! The U.S. is a big place and some cicada populations have yet to be documented.


Question: Why don’t I have periodical cicadas in my area, but the information on your website indicates that I should?

Answer: Two possibilities: 1) they went extinct or otherwise died off in your area, or 2) they aren’t everywhere in a state – normally there are large gaps in their range.


Question: What are stragglers?

Answer: Stragglers can emerge 1 or 4 years early or 1 or 4 years late. Don’t be surprised if you see some periodical cicadas emerge earlier than planned this year. 17-year brood members are most likely to straggle 4 years early, and 13-year brood members are most likely to straggle 4 years late. Straggler probability chart.


Question: Why are there no Brood XI, XII, XV, XVI… ?

Answer: Perhaps you’ve noticed there are no Broods XI (11), XII (12), XV (15), XVI (16), XVII (17), XVIII (18), XX (20), XXI (21), XXIV (24), etc. Don’t worry about that. They never existed or are extinct (XI, XXI).

    I found 2 in my yard today. July 12, 2020 Kennesaw, GA

    I was going to use the Cicada Safari app, but it wants too much personal info and location. I get enough junk, spam already. Yes, it bugs me.

    Hopefully this is useful to someone tracking them.

  2. John Adams says:

    Spotted several cicada shells in my yard at Santee S.C. and looked them up and found this world of info. With all the problems we are having this year in our world is a comfort to know Mother Nature will keep on going even long after we have destroyed ourselves. I have kept one of my cicada shells, named him George and placed him in a place of honor in my artifacts collection.

  3. maggie says:

    HI There.
    I live in northern NJ and it seems to me like we ALWAYS have cicadas–every year. I love that sound on a hot summer morning.
    My son asked me why we haven’t heard any yet this year and I don’t have an answer.
    I could have SWORN I heard them this past Saturday morning, and got all happy again. But then–nothing since.
    What is going on? Is it actually possible we will have a summer without ANY cicadas??
    THank you.

    1. Dan says:

      @maggie, the Jersey annual cicadas are starting to emerge now. Here’s a list of all Jersey cicadas. You should start to hear Lyricen and Morning cicadas in the coming week.

  4. CStomp says:

    I live in the Western Suburbs of Chicago where it has turned sharply cooler this afternoon. It’s around 67 degrees and supposed to drop into the upper 50’s tonight. Will the cooler temperatures have a negative impact on the cicada activity? Not to mention yesterday’s high winds associated with Tropical Depression Cristobal, which took down a lot of smaller branches and twigs throughout the area. They seem to be calling less right now around 6pm CT on 6/10/2020.

  5. JACKIE BETTS says:

    I live in SW virginia and am experiencing Brood IX at this time…pretty amazing!
    We attract many hummingbirds to our yard and are now seeing them at the feeders only early in the morning and at dusk. Can the huge numbers of cicadas that we have on our property interfere with the nesting cycle of the hummingbirds?

  6. Tracy Mulhausen says:

    I live in Chicago’s southwest suburb of Orland Park. We must have the Brood XIII stragglers here too. I initially saw nymphs climbing walls of my house on Wednesday,June 3rd. By the weekend, my shrubs, trees, wood retaining walls and cedar siding were strewn with hundreds of not thousands of nymph shells. Today, it’s simply a massive chorus when you sit outside.

  7. howard diehl says:

    I live in the west suburbs of Chicago, and for the past week we have had a growing symphony of cicada calls. I did see a dead cicada on the sidewalk during of my walks. This started about the beginning of June, when I heard one lone cicada singing.

  8. Valerie says:

    Reminds me of the “War of the World” movie, the original one. Their constant drone sounds just like the spaceships nbn before they began laser fire

  9. tim zevo says:

    So what brood is emerging here in at least the suburbs of Chicago-DownersGrove?
    If they’re “stragglers” of brood 13 there sure is a lot of them.
    Almost as big as full emergence.
    Could a different brood have expanded or moved its territory?

    1. Dan says:

      @tim, its Brood XIII, but it may be “accelerating” to establish a new brood, or at least demonstrating the biological mechanisms that allow a brood to form another brood.

      In the eastern states we have a series of broods — XIV (14), X (10), VI (6), and II (2) — that are believed to have have derived from on another.

    2. howard diehl says:

      I live in Wheaton, and have had the same experience. These are not stragglers, the symphony grows each day

      1. Dan says:

        @howard, did you experience these cicadas in this location 17 years ago?

  10. Cindy E Farmer says:

    We are at Rendezvous Mountain State Park north of Wilkesboro and not seeing them but hearing them! Sounds like The Twilight Zone!

  11. S. Ruiz says:

    I’m in Maywood, Il and I have a kid of them they greet me every morning in my backyard especially there shells. I’m afraid of them I have to sweep them away to go out the door. I don’t sit in my yard because of them. How long will they be here???

    1. Dan says:

      @S.Ruiz. Typically 3-4 weeks.

  12. Renae Keyes says:

    Birmingham, AL. Just saw two large very dark cicadas with red eyes and almost black coloring. They were hitting against my car widow as I got out this morning.

  13. Ellen dabrowski says:

    I also have seen many shells in my yard of Magicicada as well as live nymphs in the evenings. Last night I found 28 nymphs in 15 minutes. I am just north of Chicago.

  14. Ellen dabrowski says:

  15. Michael A Firman says:

    Our brood in northern Illinois is not expected to emerge until 2024
    but this morning (June 1st 2020) we discovered a Magicicada on the
    house drying off (having just emerged). Is there somewhere to report
    this? I have photos.

    1. Dan says:

      @Michael, sounds like stragglers from Brood XIII. You can report it with the Cicada Safari app.

      1. Lawrence Godson says:

        It is also possible that they are an early (one year) emergence from brood XIII. We have them in the western suburbs of Chicago. Elmhurst, LaGrange Park, Oak Park etc..

  16. Carrie Tozzi says:

    I can hear cicadas in our area of Georgetown, SC. Have yet to find the actual bug.

  17. Patty Munson says:

    I discovered a red eyed cicada Here in Searcy County, Arkansas today. I got a photo of it. It seems to not be in any group set to emerge. May 28,2020
