Both have cocooned. Check out the size compared with Stu's finger. If you look really close you can see some gold flecks which identifies these as Monarchs.

The next pic is of the Milkweed leaves that the caterpillars eat. It's about an inch and half long and that little black dot......

it the head of the caterpillar spit out just before the cocoon closes. Kind of gross but very interesting.

If you zoom in you can make out some of the features.
