Caterpillar Update...

I was gone for a couple of days this week and boy, did they fatten up!  They've probably tripled in size in the last three days and seem to be pretty mobile.  The little brown specs are 'food' from the bottom of the container that the seem to be dragging around with them.  They are spinning more silk - can't really see it too well in the photo.  All five seem to be thriving - we'll probably have chrysalides by next week.
