The cicada is back. Find out when and where experts say they'll appear in 2025

Cicadas are returning to the U.S. this year, but their numbers are not expected to be as large as in the U.S. Spring 2024when multiple nests appear simultaneously.

Brood XIV, the second largest journal group cicadaResearchers at the University of Connecticut say the cicada, known for emerging from the ground in large numbers, is the only 17-year-old cicada to emerge this spring.

Here's what we know about cicadas in 2025:

When will the cicada come back?

Cicadas live underground for most of their lives, and after a certain number of years, they emerge once the soil temperature reaches 64 degrees. Lair XIV appears every 17 years.

Although it's unclear when they will appear in 2025, they typically appear in May and last until June. During these weeks, the cicadas mature, mate, and lay eggs, then die, and then their offspring begin the cycle all over again.

climate change It also affects the time it takes for insects to arrive. Last year, cicadas returned to Georgia nearly two weeks earlier than originally planned.

Where will the fourteenth generation of cicadas appear?

Known as the “Great Eastern Nest,” this colony has historically been found in northern Georgia, Kentucky, Tennessee, southern Indiana, and Ohio, North Carolina, Virginia, West Virginia, Maryland, and Pennsylvania, Parts of New Jersey. New York and Massachusetts.

However, UConn researchers note that the number of 14th-generation cicadas on Long Island is declining and their distribution is changing in southwestern Ohio and southeastern Indiana. The researchers say they will map and study cicada emergence in 2025 to address gaps in knowledge about these patterns.

How many cicadas will there be in 2025?

Estimating the population of any insect is difficult, and cicadas are no exception.

John Cooley, a cicada expert at the University of Connecticut, said that by 2024, hundreds of trillions or even quadrillions of cicadas are expected to emerge at the same time, when two groups of cicadas emerge at the same time.

Cicada numbers will be down this spring, but insect numbers may exceed a trillion. That number may sound extreme, but cicadas don't appear in the same place at the same time.
