Provocative and eerily beautiful, is the unusual artistic collaboration of French artist Hubert Duprat and a group of caddis fly larvae....'larvae'. The word alone gives me heebies. But you have to admit it's fascinating.
" A small winged insect belonging to the order Trichoptera and closely related to the butterfly, caddis flies live near streams and ponds and produce aquatic larvae that protect their developing bodies by manufacturing 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 benthic ecosystem. The larvae are remarkably adaptable: if other suitable materials are introduced into their environment, they will often incorporate those as well. "
