An update on the silkworms!



This is about my silkworms my silkworms can spin about 300,000 loops of silk.Each female lays about 500 eggs. Silk moths do not eat or drink during their lifetime. The adult moth almosts always emerges from in the morning,usually before 9am. A silkworm will eat about 50 times its final weight during its eating period.It hatches to a full grown lavra the silkworms increases in size by 10,000 times.The silkworms will shed their skins 4 times during it larval stage. The silkworm sheds its skin by attaching the tail end of its skin to the surface on what it is resting on. Silk moths cocoons are made from a single strand of silk. One cocoon can be made of up to half a mile of unbroken silk.

An Update from Joseph

"This week some of my silkworms have died because the food is drying up so they can't eat."

Joseph kindly brought in some photographs to show us today.
Here is a photograph of the silkworms that we have been hearing all about:

 
 
Joseph has also been caring for some caterpillars which have just transformed into butterflies. Look at this beautiful photograph of a new butterfly on Joseph's sister's hand!
 

 
Thank you for keeping us updated, Joseph- we are all finding it very interesting!

Super Silkworms, By Joseph


 
I got them two days ago and one of the eggs is nearly white. They live in a box with a net in it. They have mushy green food and they don’t do much because they are still eggs.

I will report back next week. They should hatch in about 10-28 days.
