I thought the article would discuss physics of flight, but it's about physics of iridescence. Cool, but not what I expected. I've seen butterflies fly in a stiff wind. It seems impossible even when you watch it. I was hoping for some insight into that.

Reminder that most picturesque images of butterflies are of dead ones, including the emoji!

The interior of my 3d printed parts has that exact gyroid pattern by the way. They put that in SuperSlicer, and presumably in PrusaSlicer, because it is really easy to print by running wiggly lines along x and y direction. Works great.

The most beautiful flying creature imo, they fly almost effortlessly. I often work remotely in the nature, standing hours in front of my laptop, and sometimes a butterfly or a dragonfly lands on my arm or shoulder, and stays a while. When you think about it, it's probably the safest place for them, since their predators (lizards, ..) don't come close to humans
