Chrysalis on my eaves?

Hello!

I found this structure under the eaves outside my front door a couple days ago (the gray thing -- the white fuzzy thing is just a spider egg sack). At first, I thought it was a paper wasp nest, but I haven't seen ant wasps or any comb-like portion. I think it's probably a chrysalis or cocoon of some kind, but can anyone tell me more specifically?

I live in western Washington State, USA.
