All of the footage showing rods are nothing more than motion blur created by the use of video cameras or film cameras with long exposures.
I really think this is the case. The clincher for me was a picture taken of a streetlight at night surrounded by insects. It showed dozens of very
convincing rods.
What interests me about the whole "rods" subject is that IMO it is one example of a larger phenomena.
As technology becomes cheaper, more and more people get their hands on it. That doesn't mean they really now how it works or what its limitations
are.
Some examples of this in my opinion:
Using cam-corders to shoot things far away in the sky. Video recorders designed for shooting the kid's birthday party don't do well with tiny
things far away in the sky. The result was a rash of diamond-shaped "UFOs" that were caused by aperature artifacts, focusing problems, and light
sensors being overwhelmed.
Pictures of space objects (especially Mars) that seem to show anomolies.
People don't understand the limitation of the resolutions used. People don't understand that photo editing "enhancement" can help in certain
situations, but it can't bring out data that isn't there. Editing filters CHANGE the data. I think people also forget the degree to which the
human brain is hard-wired for pattern recognition.

See. A couple of marks in a circle is perceived as a human face.
There was also another controversy much like the rods: the "orbs." Most of these pictures were taken with digital cameras and didn't take into
consideration that digital sensors don't work the same way as a film camera.
And I think "rods" are just the same kind of thing. The interation of shutter spead (or frame rate), motion blur, and the frequency of the insects
wings beating.
Please note that I am not trying to come off as an expert in any of these things. I am just repeating plausible explanations I have seen for each
one. I am just noting that there seems to be a trend of average people using relatively new technology (cam-corders, digital cameras, image-editors,
space photography) and misinterpreting the results they see.
