Well, as far as I am concerned.
Keep in mind that the frame rate for video cameras is 30 frames per second. This is the same as a camera shutter speed of slightly more that 1/30.
Insects fly at many different speeds. Some of the fastest can hit up to 30 km/hr. (or more with a tail wind
) If we assume that a moth is flying by at between 2 and three meters per second, at 1/30, of a second, the moth will have traveled between 2.4 and 3.6 inches, about the size of the “rod.” Furthermore, if you take a close up look at many of the “rod” pictures, you can actually see the individual wing beats. In fact Entomologists have used videos to study these very aspects of insect flight.
