Monarch Caterpillar forming its Chrysalis

This isn’t my video, but it’s too awesome not to share it.  I hope you can see it.  It was posted to Facebook:

I’ve been wanting to film something like this with a Pipevine Swallowtail caterpillar.   It looks like these folks had their Monarchs in a terrarium.  Maybe that’s the best way for me to go, too…  I’ll have to wait until next year, though, when the Pipevine Swallowtails are out and about again.
