unknown caterpillar

I found this this morning. It is one of the leaves to my baby cannas. Its obviously a caterpillar. I would just like to know which one. It doesnt look like its a woolly one. And the leaf was sealed shut with little threads of silk. The skin is laying in what looks like a bed of spun silk.




This is a damage done to its pot mates and neighbors, the 4 0'clocks.




And of course the little booger is nowhere to be found.

Any ideas?

 

Thank you!
