Periodical cicadas, known as Brood XIV, will emerge across New Jersey this spring after a 17-year underground wait. The emergence is expected to be smaller than the 2024 dual cicada event, but still brings excitement for nature enthusiasts.
Cicadas surface when soil temperatures reach 64°F (18°C), typically occurring from mid-April to mid-May, depending on weather conditions. As they emerge, males produce a loud chorus that can reach up to 100 decibels, comparable to heavy machinery.
Unlike annual cicadas, which appear every summer, periodical cicadas emerge in massive numbers only every 13 or 17 years. Scientists believe this strategy helps them avoid predators by overwhelming them with sheer numbers.
Despite their size, cicadas are harmless to humans and pets. However, their exoskeletons can cause mild digestive issues for animals that eat them. The emergence is brief, lasting just a few weeks, offering a rare chance to witness one of nature’s most fascinating life cycles.
