Kurcze, po polsku też znajduję takie info, za to np. na angielskiej wiki jest coś wręcz przeciwnego:
"There are more than 500 species of wild silkworms in the world, although only a few are used to produce cloth. They usually produce a tougher and rougher silk than that from domesticated Bombyx mori silkworms. Wild silks are usually harvested after the moths have left the cocoons, cutting the threads in the process, so that there is not one long thread, as with domesticated silkworms."
