Hubert Duprat is an artist living in the south of France, who began working with caddis fly larvae in the early 1980s. 

An avid naturalist since childhood, Duprat collects the larvae from their normal environments, then relocates them to his studio where he gently removes their own natural cases.  He then places them in aquaria that he fills with alternative materials such as gold spangles, semi-precious and precious stones (turquoise, lapis lazuli, coral, opals, pearls, sapphires, rubies and diamonds) from which they can begin to recreate their protective sheaths.  The images above depict the amazing results.
