These photos were taken in the middle room of the depot. This is the first photo I took in the series.
This is the photo with the bug/org.
And this is the photo I took right after the one with the bug/orb.
A possible explanation for the orb in the middle photo is that it’s a bug. While we were investigating, there was a large moth flying about in the middle room. The “orb” is pretty big and has almost an iridescent sheen to it. Moths, like butterflies, have what looks like a powder on their wings; these are actually small scales.
Science World explains that these scales “contribute to the pattern on the wings by diffracting light through a complex microscopic structure of ribs and holes.”
During the day, we see these patterns as the colors and striations on the moth’s wings. It seems possible that these same scales, in the light of a camera flash, could also refract light shone on them in the right conditions.
What do you think? Do you have photos that show an “orb” that’s big and iridescent?
