Mystery Caterpillar, Part 2

Our mystery caterpillars have entered the next phase of their metamorphosis. We now we think they will turn into moths rather than butterflies because these look like cocoons rather than chrysalids:

One "cocoon" is on the edge of the butterfly house.

The other is on the underside of a leaf. I returned it to the butterfly house upside down after photographing.
We still haven't consulted guide books. My husband already identified it and sent me the link, but I haven't read anything yet. I'm still watching closely to see what I can learn on my own.

Do you think you know what it is? Please share.
