Time to start looking for signs of periodical cicadas

Filed under: Magicicada,Periodical,United States,Video — Dan @ 1:01 am

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 Magicicada.org 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. Cicada premptively 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 deep is 65°, the conditions are good that they might emerge.

  1. 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?

  5. 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.

  9. 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….

  10. 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!

  15. 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.

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

  19. 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.

  22. 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.
