What else do silkworm babies eat besides mulberry leaves during their growth?
"Spring silkworms should not grow old, spinning silk day and night. Why begrudge their tiny bodies' end, for tangling and twining has its time." This is the "Silkworm Silk Song" written by Bao Linghui of the Southern and Northern Dynasties. A silkworm's life goes through silkworm eggs - newly hatched silkworms - mature silkworms - silkworm cocoons - silkworm moths, totaling more than forty days, showing that the growth process of silkworm babies is very short.
