Time to start looking for signs of periodical cicadas

Depending on where you live, it might be warm enough for periodical cicadas to start moving around underground, or start digging tunnels to the surface and building cicada “chimneys” above their holes. Report cicada nymph or adult sightings to Cicadas @ UCONN (formerly so cicada researchers will know where they are.

What to look for:

1) Animals can hear the cicadas stirring underground, and will try to dig them up and eat them. Look for holes (about the size of a walnut or larger) made by animals digging for cicadas.

2) Look for cicadas under stones and slates. Some cicadas will burrow their way to the surface, but they hit a large stone or slate and can go no further.

If you find them in this situation, gently put the stone or slate back. They will usually find their way around the obstruction once the time is right.

One clue that a Magicicada nymph is not ready to emerge is their eyes are still white. Their eyes turn red/orange prior to emerging (a few retain a white/blue color).

3) Cicada holes are about the size of a dime. Cicadas preemptively dig holes to the surface and wait until the weather is nice enough for them to emerge. Sometimes you can see them down in the holes.

4) Cicadas form chimneys above their holes when the soil is moist or muddy. These chimneys might look like a simple golf ball sized dome or a structure over six inches tall.

Periodical cicadas typically won’t emerge until their body temperature reaches approximately 65 degrees Fahrenheit (17-19.5 Celsius1). Their bodies are warmed by surrounding soil or warm water from rain. A good rule of thumb is, if the soil 8 inches(20 cm) deep is 65°, the conditions are good that they might emerge.

    I have them here in south Alabama! Seems they are migrating outside the projected map I found online. They put on quite a chorus this evening!

    Prince William country VA
    I have a Cicada stuck to my window screen this afternoon. I have been outside much today to look for holes.

  4. Jasmin says:

    I have lots of holes and cicadas in my yard. Bristol Virginia. Just haven’t really heard them here. I have heard them in other areas first part of spring. I have two that are on my porch on a post. They pretty much follow each other up and around post. I don’t see them move but every now and then when I look they’re in a different spot on the post!!! Why?

    1. Dan says:

      I don’t know why, but it’s been a slow to start annual season everywhere.

    2. Patty says:

      From Eastern NC: I have “tunnels” all over my lawn–in some areas they are 1-2″ apart.
      The cicadas are Very Loud in my area.

      I think they are destroying my lawn.

      1. Dan says:

        That doesn’t sound like cicadas. Might be Cicada Killer Wasps making burrows, though. Do you see giant wasps?

  5. Nicole says:

    I just started seeing them in my backyard in Ridley Park, Pennsylvania, a southern suburb of Philadelphia. I found about 5 shells in 2 days and a few holes in the ground. I was creeped out so I swatted at the shells lol. I hope I didn’t do damage.

  6. Patricia Foland says:

    I have holes all in my yard. They have been thete for a while Started with a few. Now they are all over. But i haven’t seen any Cicadas yet.

  7. Lee says:

    I found seven holes here in Tucson with a nymph in one.

  8. Ash says:

    I found a cicada this morning, and had found a nymph under a stone last week! Located in North east AL

  9. Chantel DeBord says:

    I have a bunch in my front yard I live in Baltimore (Towson) MD. They are just emerge yesterday but have had the wholes for a couple of weeks.

    1. Elyse says:

      Eek I am afraid of cicadas I couldn’t even leave the house for school when brood X came in 2004 ( Ellicott city) approximately how many have you seen

  10. Roxanna Trahan says:

    I found one in my front yard, the shell was on a long blade of grass. I stooped down to see it, then i saw him sitting right below the shell.
    I was amazed. I had never seen that before. He was green with clear wings. I brought him in the house to show my husband & he told me what it was & that it had just emerged & was drying his wings & would soon turn a different color.
    I brought it and put it on my backyard tree. Now i can hear him every day at dusk. Now i hear others from a distance.

    1. Dan says:

      Cool! If it was green and in Louisiana it is likely one of these species

  11. penson says:

    They are out and about here in Bostic, NC. Had to educate my son about them this morning when he heard them outside. lol

  12. Celine Whitaker says:

    Here in Americus Kansas we have had them for weeks! We live on two acres but they seem to like the two trees closets to our house. Really have to dodge them going in or out of the house. So ready for them to move on.

  13. T PHILLIPS says:

    I just seen 2 of them and it looks like there will be more coming up in our garden in rock hill sc

  14. Doug petty says:

    My yard is like walking on egg shells.the noise is terrible

  15. RVingPatty says:

    I am a volunteer at Visitor Center at Perry Lake, Kansas and new to Kansas. I started hearing the “roar” and just looked up these little red eyed insects. I think they are in the millions singing to the females. It is like a wave of buzzing that goes from tree to tree in a crescent, then starts again and moves around the ring of trees again. I has been a new experience.

  16. Jerri says:

    First starting appearing in Excelsior Springs, MO (north of Kansas City) about 10 days ago.

  17. ron hotchkiss says:

    I live in Lakeland Tn also. They are very loud in the woods behind my house but i havent seen the first one yet. Plan to take my grand daughter on a short hike today to see if they have emerged yet.

  18. Pattilu says:

    Sorry….Pattilu is from southern Indiana.

  19. Pattilu says:

    Appearing by the thousands in our yard and woods. Saw their chimneys in early May in the woods, but didn’t know what they were until now. Started seeing the casings and live cicada’s by the thousands about 2 weeks ago. Now the trees and shrubs are covered with all stages…live, and in and out of shells. Creepy and hard to relax outside and I’m ready for this invasion to be over.

  20. Sue says:

    That was Carbondale, IL

  21. Sue says:

    Jackson County Carbondale/Murphysboro area …emergence started a few days ago

  22. Karen Knight says:

    Hearing them in central Arkansas now.

  23. Kayre says:

    Heard them outside last night in southwest Louisiana!

  24. Cathy Epting says:

    Lakeland TN has been invaded. The old carcasses are hanging from all vertical surfaces. It sounds like the roar of motors in my back yard!

  25. Linda Oliver says:

    I started hearing the flying saucer whirr of thousands of cicadas a few days ago here in Bolivar, TN. Yesterday I removed one empty casing from my front porch (creepy!), and four more this morning. It looks like there’s an adult one at the top of my front door lintel, and I just chased something out the door that came in with me a few minutes ago. Starting to feel a little uneasy here….

  26. Nancy White says:

    still here in NE. LA. Seems they are moving toward Arkansas. Love life in the country!

  27. Denell Whittingham says:

    The Cicada’s are sounding off in N.E. Arkansas. Heard them for the first time today!

  28. Victoria says:

    They invaded my space weeks ago. I love the visit but ready for them to go:) Clinton, MS

  29. Holly says:

    Cicadas are seen here in Graves county Kentucky already with wings drying and thousands of shells all over my trees and the leaves. I saw some in shells climbing yesterday that had just emerged.

  30. Ronald Glisson says:

    New cicadas in my garden 5/15/2015 few miles west of Paducah Kentucky 42001

  31. debra says:

    Red eyed cicadas are in northeast Louisiana , I have 30 on my porch and tons of wholes in the yard ..every stage from not hatchedbto hatched drying and then flying off in morning!!!

  32. Renee Foster says:

    I had NO idea what this was but they are definitely here in NC. I pray I never see another one. Wishful thinking.

  33. Deb Proctor says:

    Our newly hatched cicadas here in MS are sounding like shirring flying saucers – loving it but eerie. Are these the cicadas you have posted here?
