How to get rid of the insect from the pupae (Silkworm) because the silk yarn is very strong and need any parts of the mouth and not the absorbent pipette as the butterflies?
You can kill the adults inside the cocoons by baking them in a hot oven. Then you can soak the cocoons in boiling water to loosen the threads. You need to find the end of the thread and place it on a winding bobbin. Then a machine unrolls the cocoon, winding the silk from five cocoons together to make one silk thread. Then the thread is woven into cloth.
