In 2020, the main periodical cicada brood expected to emerge in the U.S. is Brood IX (9). Brood IX will emerge in southern West Virginia, western Virginia, and a small portion of north-western North Carolina. This we know for sure.

OK, here’s the point of this article:
Cicadas from other broods will also emerge this year in small numbers. When cicadas emerge early or late, they’re called stragglers. Don’t get hung up on the meaning of the word. If it makes you happy, call the ones that emerge early “precursors”, “pioneers”, or “heralds”.
Members of Brood XIX (19) are emerging in parts of North Carolina and Georgia, where Brood XIX is know to exist. There’s some discussion of this over on the Cicada Discussion, Science and Study Group on Facebook. You might see them in Alabama, Arkansas, Georgia, Illinois, Indiana, Kansas, Kentucky, Lousiana, Missouri, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, and Virginia.
The rest of Brood XIX will emerge in 2024. Here’s a map.
Here’s a paper that discusses 13-year Magicicada emerging 4 years early: David C. Marshall, Kathy B. R. Hill, and John R. Cooley “Multimodal Life-Cycle Variation in 13- and 17-Year Periodical Cicadas (Hemiptera: Cicadidae: Magicicada),” Journal of the Kansas Entomological Society 90(3), 211-226, (1 July 2017). https://doi.org/10.2317/0022-8567-90.3.211
Members of Brood XIII (13) are likely to emerge 4 years early in Iowa, Wisconsin, Illinois, Indiana, and possibly Michigan.
The rest of Brood XIII emerge in 2024 (a big year for periodical cicadas). Here’s a map.
Some members of Brood X (10) should emerge 1 year early in Delaware, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Washington D.C.
The rest of Brood X will emerge next year in 2021. Here’s a map.
Here’s a screen shot from the Cicada Safari app:
Within the app, you can zoom in to see where the cicadas are appearing. Here’s a “Live Map” of the sightings from the app.Pinch and zoom to get details.
A few early Brood X in Livingston Co. Kentucky. 05/25/2020.
I will be traveling across the country and back this summer on my motorcycle. I was planning on going through North Carolina. I am wondering if you have any idea when in 2020 the cicadias will come out? I am traveling in July and August. If the brood is thick enough it might not be safe to drive. So if I had any idea when they were coming I would prefer to change my route to avoid them. Thanks for any help you can give me.
@Kathleen, They’re out now. Check out the Cicada Safari app to see where people are finding them, or try this online map. You might have to zoom in a couple times to see exactly where. Good luck!
