Cocoons: First Harvest.
and a little like plucking fruit from a tree, since each cocoon is suspended in place by a web, a 'floss' of silk, which has a slightly different structure from the silk in the cocoon.
I have let them nestle awhile in a silk scarf (which seemed appropriate), and it is interesting to see how different they are: one is significantly smaller than the rest, and one is irregularly-shaped, with a waist, and yet another is not quite opaque. Inside I can see the grub. It rattles around, still white, but clearly dead. I am thinking this one might be a good one to try to unravel, or 'reel'.
