Arizona Desert Hairy scorpions are a nocturnal, warm-desert species; specially adapted to the hot and dry desert conditions. Occupying the western two thirds of Arizona, the Colorado and Mojave desert regions of southern California, southern Nevada, and extreme southwestern Utah, the Arizona Desert Hairy scorpion is one of the largest species of scorpions in North America; growing to a length of 5.6 to 6 inches. Its large size allows it to feed on other scorpions, and a variety of other prey; including lizards, snakes, large insects, spiders, and small vertebrates. The Desert Hairy Scorpion is usually yellow, with a dark top; and lobster-like claws/pincers. It received its common name “Hairy”, from the brown hair that covers its body; used to detect vibration in the soil.

Although this scorpion is big, its venom is not very potent. The sting from an Arizona Desert Hairy Scorpion, is commonly perceived to be as painful as a honeybee’s sting. Nevertheless, an allergic reaction to its venom can be fatal. Symptoms can include: difficulty breathing, excessive swelling, and prolonged pain.

Most commonly encountered in rocky habitats, the Arizona Desert Hairy Scorpion will sometimes stray; into sandy soils. Known as a burrowing scorpion, the Arizona Desert Hairy Scorpion will dig elaborate burrows (up to 2.5 meters deep) and emerge at night to forage for prey and mates. This pest may also be discovered under rocks, containing traces of moisture.
