You tell me. While exploring Robbers Roost Canyon in Utah last week, we flipped over a rock to use it to hold down a tarp or something benign like that and found this guy. I found it to be rather beautiful. His green extremities, black body, and he was backed up into a small opening in the rocky slope. My wife found it less amusing and admitted it might not bother her so much if it wasn’t so poisonous. Anyone know what kind of scorpion this is?
