Aglaostigma, probably
Aglaostigma
is the only thing known from
Impatiens
- see comments
here
. I think I can see warts on side the 7th annulet, but can't be sure.

Sawfly larva
The plant appears to be
Impatiens
, but it would be nice to be able to see it more closely.

A crop that highlights just a few of the leaves...
should do the trick.

Still looks like Impatiens.
I would guess that caterpillar is some kind of leafroller/tier (like maybe a tortricid), and to identify those it's generally necessary to raise them to adulthood, unless you can get a specialist to examine the larva in person. If it's leaving distinctive feeding sign on a particular host plant, it might be possible to ID it that way, but this one looks like it wasn't feeding--could have dropped down from some other host plant, in search of a place to pupate.

Agree with Impatiens
I agree with Charley's ID of this plant as a species of
Impatiens
, possibly Pale Touch-me-not
(
I. pallida
)
.
