Also known as Bark Scorpion, Sculptured Bark Scorpion
Arizona bark scorpions are adept nocturnal hunters that use sensitive sensory hairs on their pincers to detect prey vibrations in total darkness. Unlike most desert scorpions, they are accomplished climbers that frequently scale trees, rock walls, and human dwellings to seek shelter under loose bark or cool crevices. Their exoskeleton glows a vivid cyan under ultraviolet light, making them easy to spot on warm desert nights.

Why interaction risk is very high
Delivers a painful neurotoxic sting; maintain a safe distance and never attempt to handle.
Why it is dangerous
Delivers potent neurotoxic venom via its sting that causes intense pain, numbness, vomiting, and potentially severe systemic effects in children or pets.
How to recognize a risky encounter
Recognized by a slender tan-to-yellow body, narrow pincers, and a long tail that rests curled sideways.
What to do
Shake out footwear and bedding in endemic regions, and use tongs or call professionals to remove individuals.
Responsible observation
Blacklight Spotting: Use a 395nm ultraviolet flashlight at night to reveal their bright glowing exoskeleton.
Climbing Hazards: Inspect walls, ceilings, and undersides of outdoor items, as this species climbs easily.
Protective Gear: Wear thick work gloves and closed-toe shoes when moving firewood, rocks, or yard debris.
