Golden chrysalis -
Aglais milberti
Colrain, Franklin County, Massachusetts, USA

I'm thinking a
Vanessa
of some sort? All I got from it was a couple of tachinids.

Nymphalis (or Aglais) milberti
is what I'd say it is. All three eastern
Vanessa
species are usually just a tad more rounded with the projections just a little less developed. Also, the coloring of the larval skin fits
N. milberti
too. I'll bet there were Nettles nearby?
Pupae of certain species of the two genera can be extremely similar. I've reared
Nymphalis milberti
and
Vanessa carye
(also called
annabella
) together, from Arizona, and I didn't even know I had two species until the first adults emerged. The larvae and pupae were nearly indistinguishible unless I looked
really
closely (and I didn't, at least not at first). Luckily you don't have
V. carye
in Mass., so it can't be that one.

Aha!
The "stubbiness" of
Vanessa
chrysalises relative to this one is exactly what I was noticing, and why I thought I'd better make sure. This one also has prominent anterior "horns" that I'm not seeing in the
Vanessa
photos, but
Aglais milberti
clearly has them:
I guess those are the projections you mean.
I don't remember the exact spot where I found this (4+ years ago), but there were certainly
Laportea
nettles on the property; probably some
Urtica
somewhere. And I saw Milbert's tortoiseshells in the garden all the time when I was living there.

You're probably right.
There are a few photos for V. cardui in the guide , but I have no idea whether American and Painted lady chrysalises (chrysali?) would even be distinguishable.

Thanks
I happen to have just looked up the plural of chrysalis, since I keep seeing different things, and Webster's gives "chrysalises" and "chrysalides" as options, but not "chrysales," which I've seen a lot. Webster's also confirmed, incidentally, that "exuviae" is both singular and plural; "exuvia" and "exuvium" don't exist according to them--despite the use of those forms all over the web and even in some entomology textbooks.
