Arizona Bark Scorpion
Centruroides sculpturatus


Use a flashlight to spot at night
The Arizona bark scorpion (Centruroides sculpturatus) is a small but highly venomous scorpion native to Arizona, commonly found in forests, desert edges, and rocky areas. Nocturnal by nature, it emerges at night to hunt insects and other small invertebrates using its venomous sting to subdue prey. Despite its small size, the Arizona bark scorpion is capable of delivering a painful sting that can be medically significant, particularly for young children or sensitive individuals. During the day, it hides under rocks, logs, and in crevices to avoid heat and predators. As both predator and prey, bark scorpions play an important ecological role in controlling insect populations while supporting larger predators such as owls, bats, and lizards.
