Excerpt from W. J. Holland's The Moth Book (1920) covering the family Bombycidae, with the silkworm moth Bombyx mori as its main subject. It gives Hampson's family characterization, notes on the caterpillar's food plants, and a section on the history of silk culture. That history runs from China and the legend of Empress Si-Ling-Chi through Byzantium under Justinian, Europe, and the American colonies. It also covers the Morus multicaulis craze of the 1830s and the growth of the American silk industry.
