I've done a bunch of research this morning on this. After studying
WSU.edu,
Stink Bugs of Economic Importance in America North of Mexico, and
Western Species here I think this must be ligata. These were found on Oregon Grape bushes.
These are probably the 3rd and 5th instars with the green adult.
I just heard from David Rider and he says for this area the two possibilites are ligata and rossiana. I'll do some more research.
