You could call it a cocoon.
They live in forests in North America.
9-10 days
The silkworm will turn into a silkmoth, not a butterfly.
They make silk...when the spin their cacoon
The silk that is made into the cloth is the thread that the silkmoth caterpillar spins to make its cocoon. Thus the cocoons are boiled to kill the pupa and free the silk thread.
Silkmoth pupae are typically killed by boiling cocoons to prevent them from emerging as moths and breaking the silk fibers. This process helps to maintain the quality, length, and strength of the silk threads for textile production. Additionally, it simplifies the extraction of silk fibers from the cocoon.
Silk worms are cold blooded. They are not really worms. They are the caterpillar of the silkmoth. The only animals that are warm blooded are birds and mammals.
IVO SAUMAN has written: 'PERIOD PROTEIN IS NECESSARY FOR CIRCADIAN CONTROL OF EGG HATCHING BEHAVIOR IN THE SILKMOTH ANTHERAEA PERHYI'
If the moth hatches, it chews its way out of the cocoon, cutting all the silk fibers. for silk production, the caterpillar is killed before it hatches, so the silk strands can be unwound and remain whole.
The Hoopa home was called a "xonta". The Hoopa home was called a "xonta".
Because all growth takes place as the caterpillar and the moths hatch with sufficient food stores to make their short life and reproduction possible without food.
It is called a home run
