How long do caterpillars stay in a cocoon?
My granddaughter and I put a caterpillar into a glass box (covered with Saran Wrap with holes poked into it) with some twigs and leaves and it built a cocoon in about a day. It's been there for a couple weeks and I fear that life, as we know it, has ended for that little feller, for reasons unknown. However, I really don't know how long to keep it before I have to dispose of it. It was some sort of furry yellow guy with a few spiky hairs on its back, maybe 2-3 cm long. I haven't been able to ID it and I can't find much info on how long they take to metamorphose to adulthood. Any guides? Any ideas? On the southern shores of Lake Michigan.
