A moth came within arm’s reach during a ride along the Dutchess County Rail Trail:
Squinting at some earlier frames that show only a tiny moving dot, the moth disappears every five frames: one wingbeat requires either 5/60 or 10/60 s = 12 or 6 strokes/second.
We continued our respective missions without incident…
The moth came much closer to the camera than it looks. I should calibrate the images with known objects at known distances, but that seems like a lot of work.
