Trillions of Cicadas Set to Emerge in Historic Double Brood Across the U.S.

For the first time in over two centuries, Broods XIX and XIII will simultaneously surface in 17 states, marking a rare entomological event.

Cicadas from Broods XIX and XIII are emerging together for the first time since 1803, affecting states across the Midwest and Southeast.
The cicadas will appear once soil temperatures reach 64 degrees, with the emergence expected to last from May through late June.
Researchers are exploring new biopesticide treatments and other methods to protect young trees from the potentially damaging effects of cicada emergence.
Entomologists encourage the public to appreciate the unique biological phenomenon of cicadas, which play a crucial ecological role.
The cicadas' loud mating calls and other behaviors, such as their unique method of excreting urine, are of particular interest to scientists.
