No, this isn’t jewelry in the shape of a Caddisfly – sorry, entomologists. It’s actually quite stranger than that: the Caddisfly larva are the artists!You need to know a little bit about Caddisfly life history to completely understand what’s going on:

Caddisflies have aquatic larvae and are found in a wide variety of habitats such as streams, rivers, lakes, ponds, spring seeps, and temporary waters (vernal pools). The larvae of many species make protective cases of silk decorated with gravel, sand, twigs or other debris.

They usually look something like this:Then artist Hubert Duprat got an idea:

Having been in the past a naturalist he knew that the larvae are remarkably adaptable: if other suitable materials are introduced into their environment, they will often incorporate those as well. So in the early eighties he started to collect the larvae from their normal environments and took them to his studio. There he gently removed their own natural cases and put them in tanks filled with his own materials, from which they began to build their new protective sheaths. When he began the project, he only provided the caddis larvae with gold flakes. Since then, the larvae have enjoyed various semi-precious and precious stones, including turquoise, coral and lapis lazuli, as well as sapphires, pearls, rubies, and diamonds.

Isn’t that neat? I know some people would be a little grossed out owning jewelry that was once an insect’s armor, but I think it’s pretty cool. Sometimes art created by nature is just as beautiful as art created by a human.(Via sex, art, and politics)
