The Silk Spinners (3x22)

Data di messa in onda: Nov 23, 1969

The life history of a moth makes a fascinating story, and some of the larger and more brightly coloured ones have an additional attraction in that they produce silk for the cocoon in which they undergo their final metamorphosis. One species in particular has been used by man for the production of silk, originally in the Far East and later in the West. The story of this sericulture is as intriguing as the natural history of the moths themselves.
