After I struggle to hunt for enough mulberry leaves to bring up silkworm,  I have got a good gain that five of my silkworms have spinned cocoons.   and I don't need to search many mulberry leaves to support them.  Till now there is still only two silkworm left not to be the form of cocoons.   Hehe, I am now waiting them for transforming into cocoons.

      To be strange, my cocoon is no larger than my colleagues'.   maybe when they were form of silkworms, they hadn't eat enough.  I have refered my colleagues who told me that about they would come out as moths after half a month.
