Silkworm farms can only be built and tended by those that have won a rank-2 Beetle Garden competition as part of the The Test of Khefre's Children.
Silkworms generate raw silk when fed the proper thistles.
There are 3 parts to a silkworm's lifecycle:
The thistle requirement will have specific amounts of 4 different vitamins in the same thistle such as: A~B~C+N~ (average Ascorbin, Biotin and Niacin, high Carotene).
Raw silk output ranges from about 1 - 1.3 raw silk per thistle. (It takes 50 raw silk to make one silk cloth)
