Ok...then it's the very young nymph of a Dock Bug...I wasn't sure earlier, since the juvenile nymphs look different - I only had one picture seen that came close to this one. But if it's most likely a nymph of the other adults you shot, then it's a Dock Bug.

Here is the green one: http://www.projectnoah.org/spottings/7398647 and the brown one: http://www.projectnoah.org/spottings/7394557

Did you take shots from the two species (even in adult state)? Don't know that much about American bugs, but it still looks like a Forest Bug to me, though the European nymphs look different - but there are some similarities.

haha nothing but forest. It's relatively old growth Sitka spruce along with 60-year-old western hemlock, Douglas fir, vine maple, big leaf maple, red alder, red cedar, salmonberry and so on.

not really generally, as far as I know. This one appears to be some forest bug - they're mostly colored in camouflage/dark colors - is there forest around?

Thanks; that's pretty much what I was thinking. I've found two different species of shield bug on those berries; I wonder if this matches one of them or is an entirely different species. Do the colors of the nymph generally match the adult?

Seems to be a Shield Bug nymph (Acanthosomatidae family)
