This black-legged meadow katydid was really going at it, and was not much bothered by your narrator sticking a brightly flashing Nikon in its grill. The paler brown region on the katydid's back is its stridulatory region of the wings, and he was rapidly rubbing them as I took the photo. As were scores of others. That day, October 30, was the last day that I heard a full-bore salvo of insect song.
Click the short video above, and you can hear the meadow katydid for yourself. We'll have to make due with such digital fare for some time, I'm afraid, if its katydids we wish to hear. July is a long ways off.
