I'll give your that what I saw was probably ready to pupate, it was late in the season. But the moth I saw was quite different than in your link. I thought I took a pic, but I can't find it. The closest I could find on Google is this -

But that's not it either. The stripes were more totally straight across and more striped. Almost like a horizontal striped tee shirt. more brown and yellow.
So all in the family but something a bit different.
