Larvae-made jewelry (video link below): These beautiful pieces are the unusual collaboration between French artist Hubert Duprat and a busy little crew of caddis fly larvae... the insects manufacture cases to protect their developing bodies ...he carefully prods them out of their own natural cases and re-houses them in aquariums filled with substitute materials...When the larvae develops its wings it abandons the case. http://www.thisiscolossal.com/2014/07/hubert-duprat-caddisflies/
Becca- by Fred Wessel (Detail in Verdaccio) Verdaccio uses a greenish grey underpainting. This method was favored by the early Italian, egg-tempera, fresco painters. It is very well suited for portrait and figurative work as the pink skin tones that were thinly glazed on top would be balanced by the green (their compliment). A greenish grey can be made using Terra Verte or a mixture of Chromium Oxide Green and Mars Black.
