(I sent this report in yesterday, but without the photo, and I had underestimated the size.)
I don't know if this is an invasive species or not. I didn't think we had scorpions in the wetlands of western Oregon.

Hi Cathy, I sent your photo on to the OSU insect lab for identification. As soon as I hear back, I'll let you know.

Hi Cathy, Jim Young from the OSU insect lab says, "It appears to be Uroctonus mordax, the California Forest Scorpion. They are uncommon but widespread. I’ve even had students collect them in the city limits of Corvallis. Their sting is painful but not deadly (unless you have an allergic reaction)."
