Are the Magicicada Periodical Cicadas coming to your town?
Brood IV and Brood XXIII will emerge in 2015. Brood IV cicadas have a 17 year life cycle and will emerge in IA, KS, MO, NE, OK, and TX. Brood XXIII cicadas have a 13 year life cycle and will emerge in AR, IL, IN, KY, LA, MO, MS, and TN. More info below...
Read this first:
- This page is strictly dedicated to Magicicada periodical cicadas (aka 17 and 13-year cicadas, and "locusts").
- This does not cover annual cicada species in the U.S.A. (cicadas that arrive every year), or cicadas outside of the United States.
- Magicicadas only emerge in the Spring and very early Summer (April-June). If you find cicadas in mid July or later, they are not Magicicadas.
- If you're in the right area, but in the wrong year, you might find some "stragglers", which are Magicicada that emerge ahead of time (or after).

Most of the maps come from C.L. Marlatt’s The periodical cicada: an account of Cicada septendecim, its natural enemies and the means of preventing its injury…. Those Brood Maps are about 100 years old; go to Magicicada.org for updated maps.
Note: 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.
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).
Figuring out if they're coming to your town:
- Verify that they're coming to your state. Check the Magicicada Brood Chart on this page.
- Check Cicada Brood Maps linked from this page to see if they're coming to your general area.
- Check to see if they're coming to your neighborhood. Good sources include:
- Check the Cicada Central Magicicada Database to see the counties where cicadas have appeared in the past.
- Ask someone who lived there 17 (or 13) years before.
- Old timers (hint: old timers usually call them locusts).
- Check your local Library for old newspaper articles.
- Check with a local college: contact the biology or agriculture departments.
- Your local county and town parks department (parks and rec). Some county parks departments plan events around cicada emergences.
- When will they emerge?
- They will emerge sometime in the Spring, for sure.
- They typically emerge once the soil 8 inches below the surface gets to 64 degrees Fahrenheit. 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.
- Cicadas in sunny areas of your yard will emerge before cicadas in shady areas.
- Cicadas in the southern-most states will emerge before cicadas in northern states.
- You can try the Cicada Emergence Formula as well.
- They're coming, and I have baby trees!
- Spray them off with a garden hose.
- Foil around the trunk (to keep them from crawling up) (thanks Deborah).
- Insect barrier tape.
- Place netting over your precious ornamental trees: Try a landscaping supply place - where you bought the baby trees in the first place.
- Bagpipes (no joke, it worked at my friend's wedding).
- Don't use pesticide - we like all insects (especially pollinating bees).
- 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...
- They're coming, and they're going to ruin my wedding!
Important: Magicicadas won't emerge everywhere in the states mentioned above. They might not exist in your town or neighborhood (particularly if trees were removed from your neighborhood). The key to seeing them, if they don't emerge in your neighborhood, is communication: networking with friends and family, checking the interactive maps on magicicada.org, checking sites like Twitter, Facebook and YouTube.
What should you look for before they emerge?
Look out for cicada chimneys (follow the link for a photo) also known as turrets. These are structures cicadas build out of soil, positioned above the spot where they will emerge.
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.
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. If you have the time, a flash light and a camera you can record this amazing transformation.
How to tell the difference between the Magicicada species:
- Magicicada neotredecim Marshall and Cooley, 2000. Virtually indistinguishable from the 17-year variety (M. septendecim).
- Magicicada tredecim (Walsh and Riley, 1868). Lower pitched call than M. neotredecim. No dark bands on abdomen; very orange.
- Magicicada septendecim (Linnaeus, 1758). Virtually indistinguishable from the 13-year variety (M. neotredecim).
Appearance of their abdomens:
M. tredecim, by comparison, have almost entirely orange abdomens:
M. septendecim also have an area of orange coloring between the eye and the wing (pronotal extension):
Sounds like "Pharaoh, Pharaoh!"
- Magicicada tredecassini Alexander and Moore, 1962. Virtually indistinguishable from 17-year M. cassini.
- Magicicada cassini (Fisher, 1851). Virtually indistinguishable from 13-year M. tredecassini.
Appearance of their abdomens:
Note how it makes quick burst of sound, followed by some rapid clicks.
- Magicicada tredecula Alexander and Moore, 1962. Virtually indistinguishable from 17-year M. septendecula
- Magicicada septendecula Alexander and Moore, 1962. Virtually indistinguishable from 13-year M. tredecula.
Appearance of their abdomens:
M. septendecula & M. tredecula have stripes that feature more black than orange.
Female on left; Male on right.
Note the "tick, tick, tick" rhythm of its call.
