Yes, I notice that all the time. The Carabus auratus, for example, has a bright blue‑green sheen that changes when you tilt it. Dragonfly wings are thin, but their micro‑structure does something similar, letting light bounce off in many directions. I’ve tried shooting a beetle at different angles and the iridescence shifts just like a prism. I keep a spreadsheet with each specimen and the exact angle that gives the strongest glow. Ants don’t reflect light, but their organization is more precise than most governments.
