Trichopterae is “an unusual artistic collaboration between the French artist Hubert Duprat and a group of caddis fly larvae,” write the people at Cabinet magazine.
“The larvae are remarkably adaptable: if other suitable materials are introduced into their environment, they will often incorporate those as well. … After collecting the larvae from their normal environments, [Duprat] 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…precious stones.”
