Well spotted, @grildrig. Really interesting photos! I'm not totally convinced that's a butterfly, although I would have to see it up close to be sure, and get your observations on some of its behaviour as it was drying its wings.

It might be a brightly coloured moth (would be interesting to see its habitat to see if that colouring would help with confusing predators). Telltale signs: moths hold their wings down, while butterflies hold theirs up - granted, during the drying period immediately following emergence from the chrysalis, they tend to slowly flap them open and closed up - butterflies also have little "knobs" at the end of their antennae, while moths' antennae are feathered (some with a slim profile, others with quite a wide, extravagant profile), and finally, butterflies metamorphose in chrysalids (hard shell) rather than cocoons (spun silky containers). That shell does look more like a chrysalis than a cocoon. Would be really interesting to know more about what wing-drying behaviour you observed, and what this lovely creature's antennae looked like.
