Periodical cicada Brood VIII (Eight) will emerge in 2019 in western Pennsylvania, eastern Ohio, and the tip of the northern panhandle of West Virginia…
- Millions of these:
- Cicada insects with a 17-year life cycle.
- Some people call them “locusts” but they’re really cicadas.
- Which species: All three 17-year species, Magicicada septendecim, Magicicada cassini and Magicicada septendecula. How to tell the difference between the species.
- NOT the green ones that arrive annually.
- When: Typically beginning in May and ending in late June. These cicadas will begin to emerge when the soil 8″ beneath the ground reaches 64 degrees Fahrenheit. A nice, warm rain will often trigger an emergence.
- Pennsylvania: Allegheny, Armstrong, Beaver, Butler, Clarion, Indiana, Lawrence, Venango, Washington, Westmoreland. Pittsburg is the largest city within the brood area.
- Ohio: Columbiana, Mahoning
- West Virginia: Hancock
- Magicicada.org has the most up to date map..
- County data is from the Cicada Central Periodical Cicada Record Database
- Why: Why do they emerge in massive numbers every 17-years? In a nutshell, the long life cycle has helped them avoid gaining a specific above-ground predator, and the massive numbers allow them to satiate predators in general, allowing enough to survive and preproduce.
