I did a little more searching on it-
"Not only does the mother’s body give protection for her babies, but it also provides them with food. The babies feed on the LIVING body of the mother. Then the mother worm dies, and her body excretes a crimson or scarlet dye that stains both the wood to which she is attached and her baby worms. They remain crimson coloured for their entire life. On day four, body of the mother worm loses its crimson colour and turns into a snow-white wax which falls to the ground like snow.
Isa 1:18 “Come now, and let us reason together,” Says the LORD, “Though your sins are like scarlet, They shall be as white as snow; Though they are red like crimson, They shall be as wool.""
