       | 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

         | Those two, butterfly and dragonfly, could hardly be more
         | different - sort of humorous to put those two creatures in the
         | same thought. Dragonfly is the most accurate predator in the
         | whole animal kingdom.. making falcons and large cats look like
         | beginners. Meanwhile the butterfly is unable to hunt at all, a
         | truly powerful "changeling", starting life as a worm-like
         | thing.

           | sure but they're both cool bugs so they belong together imo

       | 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.

       | 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.
