In the Spring and Summer we often hear the sound of one or several corkscrews coming from pine logs. It’s weird in a funny way, and any time we’ve tried to investigate we didn’t find the culprit. Whatever is doing this stops when you move the log.
We finally got to the bottom of it, and found the bug responsible. Its mandibles must be quite strong to make such a ruckus. I’m not sure what they’re digging for, food and protection I assume. I had ran into them cutting wood before, they get bigger. You can see the byproduct of all the digging it’s done.
Yuck
I think it’s a Raghium Inquisitor, or ribbed pine borer. Makes sense.
