What do silkworms eat?
Silkworms only eat mulberry leaves and/or artificial silkworm diet (Silkworm Chow). If you are going to feed the newly hatched silkworms mulberry leaves instead of Silkworm Chow be sure and only feed them the new growth (tiny 1/2 to 1 inch leaves) or they will not be able to eat them because their jaws are too weak. Place only one tiny new leaf in the petri dish until it is completely eaten. Then repeat at least once a day until they are large enough to eat the larger leaves. Once they taste mulberry leaves it is difficult to get them to eat Silkworm Chow. Some customers that have mulberry trees raise them on Silkworm Chow until the worms are large enough to eat the tougher mulberry leaves. The worms will readily switch from Silkworm Chow to mulberry. Most customers do not have a mulberry tree and therefore raise their silkworms year around on only Silkworm Chow.
