Homepage: 17 & 13 Year Cicada Broods

  • The next periodical cicada emergence will occur in 2017 and feature Brood VI, with a chance of stragglers from Brood X.
  • This page is strictly for Magicicada periodical cicadas, aka 17 & 13-year cicadas, aka "locusts".
  • This does not cover annual cicada species in North America and other parts of the world.

The Brood Chart:

The Brood Chart features the names of the broods, their life cycle length, when they will emerge next, which states they'll emerge in, links to Maps, the species that will emerge, other other information. Click the maps for larger, detailed maps.

When will they emerge?

Generally speaking, these cicadas will begin to emerge when the soil 8" beneath the ground reaches 64 degrees Fahrenheit. A nice, warm rain will often trigger a 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 out for cicada chimneys also known as turrets. These are structures cicadas build out of soil, positioned above the spot where they will emerge.

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.

Cicadas Under Stones & Slates

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

What do they look like when they emerge:

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

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

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 exiting 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:

'decim

17-Year 'decim:

  • Magicicada septendecim (Linnaeus, 1758). Virtually indistinguishable from the 13-year variety (M. neotredecim). Broods: I-X, XIII, XIV. More info.

13-Year 'decim:

  • Magicicada neotredecim Marshall and Cooley, 2000. Virtually indistinguishable from the 17-year variety (M. septendecim). Broods: XIX, XXIII. More info.
  • Magicicada tredecim (Walsh and Riley, 1868). Lower pitched call than M. neotredecim. No dark bands on abdomen; very orange. Broods: XIX, XXII, XXIII. More info.

Appearance of their abdomens:

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

Male on left; Female on right.

M. tredecim, by comparison, have almost entirely orange abdomens: M. tredecim from Ohio in 2014.

Other features:

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

Song:

M. septendecim Call:

Sounds like "Pharaoh, Pharaoh!"

'cassini

17-year 'cassini:

  • Magicicada cassini (Fisher, 1851). Virtually indistinguishable from 13-year M. tredecassini. Broods: I-V, VIII-X, XIII, XIV. More info.

13-year 'cassini:

  • Magicicada tredecassini Alexander and Moore, 1962. Virtually indistinguishable from 17-year M. cassini. Broods: XIX, XXII, XXIII. More info.

Appearance of their abdomens:

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).

Song:

M. cassini Call and Court:

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

'decula

17-Year 'decula:

  • Magicicada septendecula Alexander and Moore, 1962. Virtually indistinguishable from 13-year M. tredecula. Broods: I-VI, VIII-X, XIII, XIV. More info.

13-Year 'decula:

  • Magicicada tredecula Alexander and Moore, 1962. Virtually indistinguishable from 17-year M. septendecula. Broods: XIX, XXII, XXIII. More info.

Appearance of their abdomens:

M. septendecula & M. tredecula have stripes that feature more black than orange.

Song:

M. tredecula Call:

Note the "tick, tick, tick" rhythm of its call.

Figuring 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 biology or agriculture departments.
    6. Your local 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.
    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. They're coming, and I have baby 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. Place netting over your precious ornamental trees: Try a landscaping supply place - where you bought the baby trees in the first place.
    5. Bagpipes (no joke, it worked at my friend's wedding).
    6. Don't use pesticide - we like all insects (especially pollinating bees).
  6. They're coming, and they scare me!
    • Get a grip! They're only bugs.
    • 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, and are another North American species, or 3) you live on a continent other than North America, in which case, try one of these pages.
    • Question: Why don't have periodical cicadas in my area, but the 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 Brood 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 exinct (XI, XXI).
