The first few days.

 Little silkworms spend their days looking for fresh tender leaves and munching, munching!

 At this stage they're only about 7mm long max. These photos are taken with a macro lens.

A" traffic jam" at the end of the stalk!

The first fews days are part of the first "Instar". A change is happening in this photo as the skin is starting to shed. Their heads (I think of them as little black caps) are black.
