Wild silks have been known and used in many countries from early times, although the scale of production is far smaller than that from cultivated silkworms. Silk cocoons and nests often resemble paper or cloth, and their use has arisen independently in many societies.[1]
Large nests can be more than a meter long, but they average less than half that size ... most authors consider that G. psidii was the main source of silk in the commerce of the ancient Mexicans before and during the time of Moctezuma.
