I'm so glad I brought the Monarch caterpillar in the house yesterday. This morning, when I came downstairs to check on it, it was hanging in the 'J' position, preparing to pupate. I had put the tree branch in there to provide a hanging spot for it, but he attached himself to the panty hose covering I'd put over the bowl.
I checked it all morning and didn't see much action. It was just hanging there. Then about an hour after I'd checked it the last time, I looked in the bowl and saw this:
WOW. That happened fast. I hate that I missed the start of this process, especially when the bowl is sitting not fifteen feet from where I've been sitting for the last couple of hours. His final shed skin is lying in the bottom of the bowl, but this stage isn't complete and the pupa is wiggling quite a bit as he finishes creating his glistening green casing. I can still see his stripes through the back of it and the golden dots at the bottom of the pupa are not yet prominent, because it hasn't yet reached true chrysalis status. I'm sure it won't be long before it looks like the one Mom found in the Children's Garden.
Once this stage is complete, he will hang like this for about a week. Then the miracle continues as the butterfly emerges. Stay tuned!
