Artisans Angkor
When the worms have grown enough, they are put in baskets. From there, they will spin their cocoons in five days and will produce about three hundreds meters of silk each. The cocoons are then put in sunlight to avoid them undergoing their metamorphosis into mature moths. However, 20% of them reach the breeding process and the female moths will lay and hatch its eggs within nine to twelve days.
The cocoons are soaked in hot water in order to soften the sericin (also known as silk gum) which coat the fibres and stick the cocoons together. Silk threads are then unwound and reeled together to produce a single thread. Weavers at Angkor Silk Farm make both raw silk and fine silk that do not have the same texture at all. Sericin has not been completely removed from raw silk threads, which will give a rougher texture to the fabric at the end.
Eastern tent caterpillar
The newly hatched caterpillars initiate the construction of a silk tent soon after emerging. They typically aggregate at the tent site throughout their larval stage, expanding the tent each day to accommodate their increasing size. Under field conditions, the caterpillars feed three times each day, just before dawn, at midafternoon, and in the evening after sunset. During each bout of feeding, the caterpillars emerge from the tent, add silk to the structure, move to distant feeding sites "en masse", feed, and then return immediately to the tent where they rest until the next activity period. The exception to this feeding pattern occurs in the last instar, when the caterpillars feed only at night. The insect has six larval instars. At the last stage, the caterpillars disperse and each constructs a cocoon in a protected place. The adult moths, or imagoes, emerge about two weeks later. They are strictly nocturnal and start flying after nightfall, coming to rest within a few hours of dawn. Mating and oviposition typically occur on the day the moths emerge from their cocoons; the females die soon thereafter.
