These sculptures of indigo dyed wood contain cocoons of live silkworms (bombyx mori). They were created by Liz Burgess, and were photographed at the Ginko Gallery & Studio in Oberlin, OH (www.ginkogallery.net - ginkogallery@oberlin.net). I have posted an example of the bombyx mori silkworm at https://pbase.com/aviben/image/97621356.
