Paruroctonus utahensis
eastern sand scorpion
Paruroctonus utahensis, commonly called the eastern sand scorpion, is a psammophilic (sand-dwelling) scorpion in the family Vaejovidae. The species ranges from Utah southward to Chihuahua, Mexico, inhabiting desert grassland ecosystems with sandy loam soils. It has been observed feeding on diverse arthropods, with documented predation on the cricket Ammobaenetes phrixocnemoides. Research has demonstrated pheromonal communication in this species, with males detecting and discriminating between chemical cues from receptive versus non-receptive females.
