Species Paruroctonus boreus - Northern Scorpion

BORE-ee-uss

boreus means northern. It is found as far north as Canada.

Adults range in size from 35 to 55 mm.

Highly variable throughout its range, and depending on habitat. Throughout much of its range it is the only scorpion found. It has the basic identifiers of Paruroctonus scorpions, such as relatively robust hands and a somewhat slender metasoma/tail in which the keels do not terminate in an enlarged denticle. In most areas it is pale, light brown. In volcanic habitats it can be quite dark with a striped tail.
