Silkies the survivors

We have four thriving silkworms (two pictured above) . It would have been five, but unfortunately I think one ended up in the compost pile a couple evenings ago when I was cleaning their container. Huck and I triple counted but I couldn’t find the fifth. In any case the survivors are doing well on their meals of Ailanthus salads.  It’s supposed to be 35 days until they make their silken cocoons. Today we are on day 19 since hatching. We should look for cocoons around September 6th.
