I don't know whether this is a moth cocoon or something else. It was about 3 feet off the ground on the side of a building in the forest. Any thoughts would be appreciated. Thanks!

Moved from ID Request.
This can always be frassed later if it's decided that it has no value to the guide. I'm personally curious to learn what other tiger moth caterpillars pupate in this fashion, without incorporating their hairs into the cocoon. Is this characteristic of Hypercompe? Or of Spilosomina? Or maybe several unrelated groups?

Any votes
keep or frass?

How about Hypercompe?
After looking through Hypercompe, I found two similar photos:

Would it be appropriate to move the photo to this genus? Or would it be a bad idea since the id is not certain?

so did you save this?
id like to see who comes out of this!

I didn't save it. It would've made id much easier, but since I didn't know whether it was a moth or something dangerous, I thought it best to leave it alone and let nature take its course.

looks like the caterpiller
was murdered by a parasite. probably a wasp. wooly bears and relataives use their hairs in the coccon, this looks like a dead cat and a wasp to me

Looks like a moth pupa to me
So it could just be the caterpillar's shed skin rather than a cocoon made of hairs.

Probably something in Arctiinae
Probably something in Arctiinae (Noctuidae).

Looks somewhat like genus Hypercompe

Many thanks
to all of you for your time and insight!
