Brood X returns in Spring of 2021

Something deep underground has been burrowed eating tree sap and dreaming of the opportunity to emerge and see the bright blue sky. This organism has been in isolation for 17 years since 2004 with a dream of one day being able to make an appearance and spread its new wings. In May of 2021, Brood X Cicadas will come out from their homes underground. 


Brood X Cicadas are actually three different species of cicada that will be found in, Adams, Bedford, Berks, Bucks, Chester, Columbia, Cumberland, Dauphin, Franklin, Fulton, Huntingdon, Lancaster, Lehigh, Luzerne, Lycoming, Mercer, Montgomery, Northampton, Perry, Schuylkill, Somerset and York counties. The Eastern United States will be considered the Epicenter for this 17- year occurrence.


These Cicadas are expected to emerge in May to early June or when the ground beneath 8 inches reaches 64 degrees Fahrenheit. A nice warm rain can start to trigger their arrival and it has been documented as early as late April. You can also walk around Peace Valley Park and look for signs of their arrival cicada nymphs will start to build holes or chimneys or turrets in muddy places and this can be a sign of their arrival. If you find signs of cicadas you can document your findings on the free cicada safari website to help scientists better understand these unique insects.
