The observable effect is true, but I don't think it squares. Circles below the ceiling in the middle of the room aren't perpendicular to the window as a light source.
I see this mostly with one particular type of fly that just loves going around light fixtures, maybe they're sensitive to the EM spectrum rather than visible light?
- scotty79 3y agoI think flies might use both sky and gravity for navigation and when sky is not up it messes with them and results in circles. I don't think those circles are exactly perpendicular to the vertical direction. I think most of them are skewed.
