Hey, I’ve been watching these little cicadas, and I’m curious how the humidity levels you track might affect their chirping patterns. Do you notice any weather cues that seem to trigger more insect activity?
Kisa
I’ve noticed that when humidity goes up, insects seem a little more lively. For cicadas, a steady 70 percent plus a slight drop in barometric pressure can sometimes trigger a louder chorus. I usually jot that in my diary, but I haven’t yet matched it directly to their chirps.

That’s a neat pattern—do you record the exact pressure change? I’d love to see if there’s a consistent threshold, like a 2‑inch drop, before the chorus ramps up. Maybe we could set up a simple barometer next to the recorder so we can compare the numbers side by side with the chirp count.
Kisa
I keep a little log of pressure in tenths of an inch, so a 0.2‑inch drop is usually enough to start the chorus. Adding a simple barometer next to the recorder would let us line up the numbers with the chirp count. Let me know when you get one set up.
Bugman
Sounds good, I’ll grab a small digital barometer and set it up right next to the recorder tomorrow. I’ll send you a photo once I’ve got everything lined up—let’s see if that 0.2‑inch drop really triggers the big chorus.
Kisa
That sounds perfect. I’ll be ready to check the data when you send the photo. Just keep the recorder in a shaded spot so temperature doesn’t throw off the readings. Looking forward to seeing if the chorus really kicks off with that 0.2‑inch drop.
