Essentially, their tiny bug brains think the light is the sunset, so they keep turning to keep the "sun" at the same angle so they can go "straight." No matter how far they fly, they don't make any progress. They are trapped in this little hell we made just for them, not understanding why they can't get to where they are going.
Are they getting much science done down there? Obviously it must be helpful that all of history's greatest scientific minds are gathered in one place -- but if nobody's serving them breakfast then maybe they're perpetually hypoglycemic and not doing much good thinking.
One evening I built a campfire to keep warm on the banks of a river in southern France. As the fire got going, millions of moths poured from the trees into the flames. As the numbers increased the flames leapt higher, and the moths became the fuel.
The horror, the horror…
@alvvayson Existing research was about "how do we stop the bugs from circling our lights?". This is about *why* the bugs circle the lights. It artificially triggers the dorsal reflex, which disorients the bugs.
Which LEDs? LEDs are pretty much all giving off the same two colors to make white: blue and yellow (in a single chip made of a blue LED and yellow uv-reactive phosphor). Warm white, cool white, same thing just varying intensities of each color. Only cheap color-changing LEDs (now) will use R/G/B chips lit together without dedicated white chips. What wavelengths are they tracking?
