Paruroctonus boreus, commonly called the northern scorpion is a small scorpion species native to North America, with the broadest distribution of any scorpion on the continent. Its range stretches across much of the western United States, parts of southern Canada, and into the northern Great Plains. It typically inhabits dry, open habitats such as grasslands, sagebrush deserts, and rocky slopes, often sheltering beneath stones, logs, or in shallow burrows.
