From Business Insider: "2 cicada broods are popping up together for the first time in 221 years — and they'll meet in Illinois." From the article:
2024 is the year of the cicadapocalypse.
That's because two broods of periodical cicadas — Broods XIII and XIX — will emerge from their underground lairs simultaneously for the first time in 221 years.
The last time the two broods teamed up, Lewis and Clark began their trek through territories recently acquired through the Louisiana Purchase, the US Supreme Court heard the landmark Marbury v. Madison case, and Thomas Jefferson was president.
The article explains that "Brood XIX will predominantly appear in southern states, while Brood XIII will appear in a small section of the Midwest — mainly Illinois." And they will overlap in a small portion of Illinois, in the Chicago area.
Very interesting math on this one.
ReplyDeleteShould be extra loud in the Chicago area.
