Arizona Bark Scorpion
Centruroides sculpturatus
The Centruroides sculpturatus, the infamous 'Arizona Bark Scorpion'. It is considered the MOST VENOMOUS scorpion in North America (its neurotoxic venom can be fatal for children, the elderly and at-risk subjects). It is a small arboreal scorpion (2-2.7 inches) of pale yellow or amber color, almost transparent, which allows it to camouflage perfectly with sand and light wood. Unlike most desert scorpions (Hadrurus) that live in burrows in the ground, the Arizona Bark is an exceptional climber and loves to take refuge in cracks, roofs and human houses. Fast, social (winters in huge groups) and equipped with a highly sensitive sting, its keeping is exclusively the prerogative of professionals, using armored cases.

Description de l'espèce
Geographic Origin and Habitat: The Arizona-Sonora Desert Museum reports Centruroides sculpturatus in southeastern California, Nevada, southern Utah and southwestern New Mexico in the United States, and in western Sonora, Mexico. It describes the species as a bark or crevice scorpion that may be found on trees and rock faces, as well as in rock and lumber piles and under rocks, logs, fallen saguaros and other surface objects.
Taxonomy and Genetics: The museum identifies Centruroides sculpturatus as a bark scorpion in the family Buthidae. The cited source does not provide a genetic result for this entry.
Behaviour and Habits: The museum reports that this species climbs and may be found on trees and rock faces; it also reports winter aggregations of 20–30 individuals. The same source identifies it as the only medically important scorpion in the United States.
Morphology and Sexual Dimorphism: The museum describes the bark scorpion as straw-coloured, with very thin chelae and tail and a tubercle on the telson under the sting. The cited source does not provide sexual-dimorphism measurements.
Soins, reproduction et cohabitation
Terrarium Setup: The U.S. National Park Service describes Centruroides sculpturatus as desert-adapted and reports a preference for riparian habitats in the Grand Canyon. This natural-history account does not establish captive enclosure dimensions, substrate depth, or a husbandry protocol.
Lighting and Heating: The source reports nocturnal activity but does not provide captive lighting or temperature parameters; none are inferred here.
Humidity and Hydration: The source describes a preference for riparian habitat within one protected-area context, but does not establish captive humidity or hydration parameters; none are inferred here.
Feeding and Supplementation: The source reports use of pincers to grab small insects. It does not provide a captive feeding schedule or supplementation protocol.
Compatibility and Coexistence: The cited account does not test cohabitation or establish compatibility criteria; no recommendation is inferred.
Health and Common Diseases: The source states that the tail is highly venomous and advises observers not to handle the animal. It does not provide a veterinary or disease-management protocol.

Profil d'invertébré terrestre
- Régime alimentaire
- Carnivore
- Centruroides sculpturatus is an active predator that feeds on a variety of insects and other small invertebrates. In captivity, a steady supply of crickets, locusts, and roaches serves as the staple diet. They use their pincers to grasp prey and their stinger to subdue it if necessary. Juveniles require smaller, softer prey items fed more frequently. Always remove any uneaten food to prevent stress and maintain a hygienic enclosure.
- Taille adulte
- 8 cm
- Mode de vie/microhabitat
- Arboreal
- The lifestyle of Centruroides sculpturatus demands a carefully structured environment that caters to its specific terrestrial or arboreal nature. Owners must ensure a proper temperature gradient, allowing the animal to thermoregulate as needed. Their enclosures should offer multiple hides and climbing opportunities if appropriate for the species. Solitary housing is absolutely necessary to prevent territorial disputes and injury. Maintaining high standards of hygiene is critical for their long-term health.
- Cycle d'activité
- Nocturnal
- The activity pattern of Centruroides sculpturatus typically aligns with crepuscular or nocturnal cycles. During the day, they remain securely tucked away in their hides to avoid desiccation and predators. As light levels drop, they emerge to actively forage, hunt, or explore their immediate surroundings. Artificial lighting in their enclosure should mimic natural day-night cycles without being overly intense. Disruptions to this cycle can cause feeding strikes or lethargy over time.
- Sociabilité
- Gregarious
- They are a highly communal species, especially evident during the winter months in the wild. They can be successfully kept in large, peaceful groups in captivity, provided they have adequate vertical climbing space.
- Reproduction
- Oviparous
- Reproduction in Centruroides sculpturatus requires careful conditioning and precise environmental parameters to ensure success. The male must be properly introduced to the female's enclosure to avoid immediate predation or aggressive behaviors. Following successful mating, the female will typically begin to construct an egg sac after a gestation period that varies by species. It is crucial to monitor the temperature and humidity to ensure the viability of the eggs. Once the young emerge, they should be separated promptly to prevent cannibalism.
- Venimeux
- Yes
- Tolérance aux manipulations
- Display only
- Handling Centruroides sculpturatus is generally strongly discouraged due to the risk of stress to the animal and potential injury. A fall from even a short height can result in a fatal abdominal rupture or severe trauma. If moving the specimen is absolutely necessary, use a soft catch cup or a sterile brush to gently guide them. Owners should respect the creature's need for personal space and observe them strictly as display animals. Avoiding direct handling minimizes the chance of unpredictable defensive bites or stings.
- Brumation
- Non requise
- In its natural habitat, Centruroides sculpturatus may experience seasonal cooling that slows down its metabolic rate. In captivity, true brumation is rarely required unless breeding is explicitly planned. If temperatures naturally drop during winter, feeding frequency should be adjusted accordingly to match their reduced metabolism. It is important never to let the enclosure become freezing or excessively damp during these cooler periods. Careful monitoring ensures the specimen remains healthy until warmer conditions resume.
- Mue
- Regular
- Molting is a critical and highly sensitive phase in the life cycle of Centruroides sculpturatus. Leading up to a molt, they will often refuse food, become sluggish, and sometimes seal themselves entirely inside their hide. It is absolutely crucial to maintain proper humidity and never disturb the animal while it is molting. After shedding its exoskeleton, the animal will be extremely soft and vulnerable for several days. Feeding must be strictly withheld until the fangs or pincers have fully hardened to prevent fatal injuries.
