Aristotle said “Art not only imitates nature, but also completes its deficiencies.” Artist, Hubert Duprat uses nature to create art and, in a sense, jewelry for the natural world. The images seen here illustrate the results of an unusual artistic collaboration between the French artist Hubert Duprat and a group of caddisfly larvae. The caddisfly live around streams and ponds and produce aquatic larvae that protect their developing bodies by manufacturing armor in the form of sheaths, or cases, spun from silk and incorporating substances—grains of sand, particles of mineral or plant material, bits of fish bone or crustacean shell—readily available in their ecosystem. The larvae are remarkably adaptable: if other suitable materials are introduced into their environment, they will often incorporate those as well.

Dupart took this one step further by introducing precious and semi-precious materials to the larvae’s environment, the results are truly amazing. After collecting the larvae from their normal environments, he relocates them to his studio where he gently removes their own natural cases and then places them in aquaria that he fills with alternative materials from which they can begin to recreate their protective sheaths. He began with only gold spangles but has since also added the kinds of semi-precious and precious stones (including turquoise, opals, lapis lazuli and coral, as well as pearls, rubies, sapphires, and diamonds) seen here.

The insects do not always incorporate all the available materials into their case designs, and certain larvae, Duprat notes, seem to have better facility with some materials than with others. Additionally, cases built by one insect and then discarded when it evolves into its fly state are sometimes recovered by other larvae, who may re-purpose it by adding to or altering its size and form.

So in this situation, who is the artist? Is it the man who simply gives the insect the material? Or is the bug the artist, and the man who gave them the material just a financier of sorts?
