Eew.

Although it's not unusual for artists to be, well, unusual, French artist Hubert Duprat has an especially strange way of expressing himself: by blinging up fly larvae.

In case you're wondering, this is a Caddis fly larvae in a shell it made for itself out of the fancy materials Duprat gave it to work with. Duprat collects the larvae from their natural habitat of ponds and streams and puts them in an aquarium where they make their shells in a controlled environment consisting of gold, pearls, and other precious stones. From what I can gather he doesn't do much with the larvae after that and they soon become full-fledged Caddis flies, leaving their discarded shells behind for other larvae to use and modify for themselves.

Interesting, but eew.
