Mysterious Ticking Noise
When we were all outdoors around the fire in the dark, I kept hearing a mysterious ticking noise coming from the trees.
I love the internet - I'm pretty sure it was the greater angle-winged katydid, Microcentrum rhombifolium.
The website Singing Insects of North America has a .wav file here. Tick tick tick to you, too, Mr. Angle-wing!
