What was the explanation if this wasn't it? The sort of "layman's-explanation" I was given was basically that insects fly in such a way that the light stays fixed in their view - so basically in the same facet(s) of an insect eye during flight, and that this causes them to circle around the lights. This seems to just scientifically confirm the hypothesis we were always told.
That makes sense. But at night that makes it point topside at moon? Which is basically "constantly tilted" of the moon is low?
(I read the article, but admittedly quickly, should probably read again)
What I understood was, it's not really about the moon at all, just that "the sky" is lighter than "the ground", and roughly orienting based on that works as a heuristic. Light & dark hemispheres, not the brightest spot.
