Arizona Bark Scorpion

Looks how to spot one

exoskeleton

Arizona bark scorpions have a slender, segmented body with a long, narrow tail that curves forward. Their exoskeleton is covered in a waxy layer that helps them hold onto water in the dry desert. Under ultraviolet light, they glow a bright bluish colour, which makes them easier to spot at night.14

Personality what they are like

Arizona bark scorpions are shy, nocturnal creatures that prefer to hide and hunt at night. They are not aggressive but will sting if they feel threatened. Their venom is medically significant to humans, so they are best treated as a hands-off pet for observation only. Handling is not recommended.546

Daily activity how busy a day looks

Low. They are nocturnal and spend most of the day hiding. At night they hunt and explore. A 10-gallon terrarium with hiding spots is sufficient. No exercise needed beyond natural movement.5

Grooming and care the hands-on bits

Very low. They do not need grooming. The main care tasks are maintaining correct temperature (80-90°F / 27-32°C) and humidity (30-40%), providing a water dish, and cleaning leftover food. Watch for signs of dehydration or moulting problems.5

Home where they are happiest

A secure 10-gallon glass terrarium with a tight lid (they are excellent escape artists). Substrate: 3-4 inches of sand and peat moss mix for burrowing. Provide hiding spots like cork bark, rocks, or logs. Temperature: 80-90°F (27-32°C) during the day, with a slight drop at night. Humidity: 30-40%. A shallow water dish is needed. They are venomous and should not be handled. In some regions, keeping venomous animals may be regulated; check local laws.546

Food basics what goes in the bowl

Carnivorous. Feed live insects such as crickets, roaches, and mealworms. Young scorpions should be fed every other day, adults once a week. Dust prey with calcium or vitamin supplement occasionally. Remove uneaten food after a day.5

Company who they like around

Solitary. They do not need companionship and can be kept alone. They are venomous and should not be handled. In the wild they hibernate in groups, but in captivity they are fine alone. Check local regulations before acquiring, as venomous animals may be restricted in some countries or states.546

The story where it all began

The Arizona bark scorpion has been known to science since the 19th century and is famous as the most venomous scorpion in North America. It has a long history of being both feared and respected in the Sonoran Desert. In recent decades, it has become a popular pet among invertebrate enthusiasts because of its striking appearance, interesting behaviour, and relatively simple care. However, its potent venom means it is not a beginner pet and is best kept for observation only.15
