Inchworms - Day 13

We are getting some action here.
so, last night I saw one of the inchworms moving like it was digging in the dirt. its not digging as much as it was moving the dirt around creating some kind of room. Today I saw two of them in the early stage of Pupa stage (because they are still moving) in the big jar, and one looks like its getting started in the second, smaller jar.

the inchworms as its known, don't like the herbs or the plants that don't have woody stem, but they like this one in the pictures and its nice to give them something I don't really want in my garden from time to time.

I read that the pupa stage takes several weeks. I don't know if there is anything I can do to help them to transform faster.. temperature or humidity or something.. I don't know.
