The strange noises you're hearing outside — like locusts or something similar — are actually quite normal for late summer in Pennsylvania. Here's what's likely going on:
🦗 What You're Hearing: The Summer Insect Chorus
Pennsylvania is home to a rich variety of night-singing insects, especially in August. The sounds you're hearing could be from:
1. Katydids
- These are large green grasshopper-like insects.
- Their call sounds like “ka-ty-did” — a harsh, rhythmic pulse repeated every second.
- They often sing in unison, creating a chorus from the treetops [1].
2. Crickets
- Crickets produce a steady, high-pitched chirping sound, especially at night.
- Their song is created by rubbing their wings together (stridulation).
- Ground crickets, tree crickets, and field crickets all contribute to the nighttime soundscape [1].
3. Cicadas
- Cicadas are louder and buzz during the daytime, not night.
- Their sound is a raspy, electric-saw-like buzz that can last for 15 seconds or more [1].
4. Conehead Katydids & Meadow Katydids
- These produce rapid buzzing or high-pitched trills, sometimes resembling a bug zapper or a faint ticking.
- Some species are so high-pitched that not everyone can hear them [1].
5. Locusts (Grasshoppers)
- True locusts are rare in Pennsylvania, but grasshoppers are common.
- They produce clicks, chirps, and dry rustling sounds, especially when flying or in dense vegetation [2].
🌙 Why It’s So Loud Right Now
Late summer is peak season for insect mating calls. Males sing to attract females, and the warm nights amplify their activity. The mix of katydids, crickets, and grasshoppers creates what some call “nature’s orchestra” — a sign that the seasons are slowly shifting.
If you’re curious, I can help you identify the exact insect by sound or even guide you to recordings so you can compare. Want to explore that?
