Thanks for the comments,everyone! Mark, thanks for the ID. It shouldn't have taken so long, I was just unsure about labeling it brunnea, in case there were others in Oregon. Apparently that's the most common NA species (maybe the only one), it's probably correct.

It is very strange. It seems very dangerous. It is of Peñarol soccer team. Maybe, If it pricks you a lot it may be dangerous...We are lucky that we don´t have them in Uruguay.
