US Preps for Trillions of Cicadas as Two Broods Emerge Together
TL/DR –
Trillions of cicadas, specifically two groups known as Brood XIX and Brood XII, are set to emerge from the earth across the midwestern and eastern United States, an event not seen since 1803. Brood XIX, the largest of all periodical cicada groups, will emerge after a 13-year dormancy, at the same time as Brood XII, a smaller group that appears every 17 years, with the event taking place in up to 16 states. This occurrence, often referred to as “cicada-geddon” or “cicada-palooza”, will result in a large noise from the insects, and after a period of mating and being eaten by predators, they will return underground to restart the cycle in July.
Trillions of Cicadas to Emerge in the US
A rare event of two cicada broods – Brood XIX and Brood XII – is set to occur after nearly 220 years. These insects, often resembling cockroaches with bulging orange eyes, live underground feeding on plant sap before emerging en masse to the surface.
Unusual Synchronization
This year, the synchronization of Brood XIX, the largest group, and Brood XII, appearing every 17 years, is expected. This event, known as “cicada-geddon” or “cicada-palooza”, will result in trillions of cicadas covering up to 16 states including Maryland, Oklahoma, Illinois, and Alabama. The resulting cacophony will rival the noise of a revving motorbike.
The Cicada Lifecyle
Post mating and predation, the cicadas will begin their life cycle anew in July. This spectacle, although concentrated in central Illinois, will be noticeable throughout the US, presenting a unique view of all seven periodical species found in the country.
Natural Wonder or Disturbance?
Cicadas pose no threat to humans or pets, but they might expel jets of urine when threatened. Nevertheless, this pattern of eruption serves an essential ecological purpose. Some enthusiasts are planning trips to witness this spectacle, while others are considering escaping the onslaught.
Climate Change Impact
Although a wonder to behold, this natural process might be disrupted by global heating. Cicadas emerge when the soil temperature reaches about 64F (17C), a process potentially scrambled by fossil fuel burning. “It could mess with their phenology. If they come out earlier than usual, it can be problematic for them,” warned Catherine Dana, a cicada specialist at the University of Illinois.
A Time for Introspection
This event serves as a chance for introspection. “Think about where you’ll be in 13 or 17 years. It’s a time for introspection,” says John Cooley, a cicada expert at the University of Connecticut.
