Cocoons! (part 2)
It is interesting to compare them with a video taken about four hours before, just here. The silkworms seem to construct a messy support web first, and then make smaller and smaller movements until they are enclosed in a cocoon. At the moment, in this video, the one on the egg carton can still rotate, but soon I expect it will not even be able to do that.
This must seem mundane and boring to some people, I suppose, but to me it is extraordinary.
