Brood XIV cicadas have returned to parts of Pennsylvania after spending 17 years underground. These large, buzzing insects are emerging in large numbers to breed during their short time above ground.
According to Michael Skvarla, assistant research professor at Penn State, the loud sound people hear is male cicadas calling to attract females. While a single cicada can be noisy, thousands calling at once can create an overwhelming buzz in affected areas.
Counties like Blair, Centre, Clearfield, Clinton, Huntingdon, Mifflin, and Potter are among those expected to experience this emergence. In 2025, cicadas may also appear in additional counties including Adams, Bedford, Berks, Cumberland, Luzerne, and York, according to Penn State Extension.
The emergence is not just about sound. Cicadas play an important ecological role. Their mass presence provides a food feast for birds, squirrels, and other animals. This helps many wildlife species feed their young during the breeding season. “Periodical cicadas are great food for a lot of animals,” said Skvarla. “Many birds, if they’re big enough, will eat them. Small mammals will also eat them, things like squirrels, and so animals that can feed on periodical cicadas generally do much better in terms of rearing young.”
Their survival strategy relies on overwhelming numbers. With thousands emerging at once, predators quickly get full, allowing most cicadas to survive and reproduce.
Cicadas are harmless to humans and pets. However, when females lay eggs, they may damage young or stressed trees. Experts suggest using temporary coverings to protect these plants.
Despite their eerie appearance and loud noise, cicadas are a natural wonder. They offer a unique opportunity to observe nature's cycles and hear a rare insect symphony.
Residents are encouraged to enjoy the experience safely, knowing it won’t return for another 17 years. It’s a brief, fascinating event that supports local ecosystems and reminds us of the rhythms of the natural world.
