Are you ready for the great cicada emergence of 2024?
What’s happening now?
The cicadas are coming home to roost! Or, rather, mate. Thanks to the
synchronization of the 13- and 17-year-cycle cicadas — which only happens once in every 221 years —
trillions of periodical cicadas known as Brood XIII and Brood XIX are emerging from the ground for a mating ritual.
This noisy ritual, which begins four to five days before the cicadas emerge, peaks with the male cicadas loudly buzzing in hopes of securing a mate. The cicada song can reach up to 100 decibels. Here's how it sounds:
When the ritual is done after a few weeks, the cicadas die and leave their carcasses. These carcasses look like tan shells in the shape of the cicada and can be found on the ground or attached to trees and plants.
Where and when is this happening?
These two cicada groups happened to make a home next to one another but won’t overlap too much, with the exception of parts of Illinois. Brood XIX will appear in parts of the Midwest and Southeast, in states like Missouri, Illinois, Louisiana, North Carolina, South Carolina, Virginia, and Maryland, while Brood XIII will primarily be seen in Illinois while also extending into parts of Wisconsin, Ohio and Iowa.
Cicadas will emerge earlier in warmer parts of the country, with the earliest-known appearance coming in mid-April. Most cicadas, however, are expected in mid-May or early June. The whole cycle lasts about a few weeks after they emerge.
What are 'zombie cicadas'? Should we be worried?
The cicadas may be extra-frisky this year, thanks to
a sexually-transmitted fungal pathogen called massospora cicadina that makes them very eager to mate. Unfortunately, it’s not all fun and games for the cicadas, as
this fungus essentially zombifies them.
While these cicadas are not literally undead, the cicadas infected with the fungus, which has mind-controlling elements similar to that of hallucinogenic mushrooms, have their backsides taken over by chalky white fungal spores. This ultimately causes their genitals — as well as other body parts — to fall off, meaning that the fungal infection is ultimately fatal. What’s particularly strange is that these infected insects also exhibit hypersexual behavior as a function of the fungus — so when they do attempt to mate, they spread the fungus. While we don’t know how many cicadas are infected with the fungus, in 2020,
10% of a brood of cicadas in the Midwest were infected.
The good news? These cicadas, zombified or not, are harmless to humans.
