Just a few days ago, I was stepping in through my studio door and right near the threshold, I spotted this creature. It was already dead. It seems odd that a scorpion would live in Montana, but the Northern Scorpion apparently lives around sandstone cliffs in the Billings area.
This is only the third time we have seen a scorpion since moving here in 2001. The others were much smaller (and were also found inside the house, by the way). I imagine it was seeking a spot to hibernate when it crawled in under the weatherstripping on the door. It looks like it has been stepped on.
