This actually squares with the study, no? I mean, when they are inside - and it's my experience as well - they might take the window as the main source of light and think that's the sky, so they start to fly in circles.
- scotty79 3y agoThat's probably it. When the "sky" doesn't align with gravity they get confused.
- shmeeed 3y agoThe 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.
