Illinois skipper I.D. #2

Here is a 2nd species which I also picked
up on yet another Colias outing of Oct.09.2021.

Again very late (I think) for these fellows but,
this time I saw 2 of these and only caught this
one.

I probably see at least 6-8 species of these little
brown/orange jobs between May and Sept.

However, because they look all so similar I don't
feel confidence in any I.D. that I would make.

So, I would again appreciate any help with this one
as well.
