These little bejeweled cases might look strange, but they're incredible. No, they're not some kind of special modern art. They're incredible because they're made by an insect.
I'm not much of a bug lover, but this is simply one of the coolest things I've ever seen (in a totally-bio-nerdy kind of way). Hubert Duprat, a french artist, had the genius if not a little out there idea to turn caddisfly larvae into artists. In the wild, caddisfly larvae create elaborate protective tubes from materials like stones, sticks, and whatever else they can find. When Duprat carefully removed their original tubes and placed the larvae in tanks with bits of gold and semi-precious and precious stones, the larvae gladly began building their tubes from the provided materials. The critters now create their tubes out of gold, sapphires, pearls, rubies and diamonds - some seriously expensive bug houses! The result is some of the most unique (and, in my opinion, fantastic) jewelry you'll ever find:
I think it's just incredible. Here's a video of a larval caddisfly in bejeweling action:
You have got to be as impressed as I am. You are, right?
