Early this morning (the morning of this photo that is) a few of the silkworm caterpillars started spinning their cocoons. When I got up in the morning, 4 of our 180 silkworms were working on their cocoons, by the evening, about 12 were working at it. The rest are still eating up a storm.
As you can see, we gave them some egg cartons and toilet paper rolls to use to attach their cocoons to. They seemed to go for the toilet paper rolls first, but one used the egg carton. I'll have to come up with more space for the others when they start spinning because there aren't enough compartments for them all right now. I plan to build a grid out of cardboard strips for them.
Since I'm getting close to being finished with the feeding phase of silkworm rearing, I started to do some research tonight about what to do with the silk. I found a really fabulous website about silkworm care and how to harvest the silk. Wormspit.com . It's the only source I've found so far that gives great detailed explanations of how to harvest and use silk without killing the pupae. I do my best to avoid killing things, so I'm excited to have found this reference.
