It is native of China, but has long been introduced into other countries of Asia and Europe, and is reared on a large scale. In America it is reared only to small extent. The Ailanthus silkworm ({Philosamia cynthia}) is a much larger species, of considerable importance, which has been introduced into Europe and America from China. The most useful American species is the Polyphemus. See {Polyphemus}. [1913 Webster]
