The Arizona bark scorpion is a small, venomous arachnid native to the southwestern United States, particularly in Arizona. It typically measures about 2 to 4 inches in length and is characterized by its slender body and long legs. This species is known for its yellowish-brown color, which helps it blend into its desert surroundings. These scorpions are primarily nocturnal and are often found hiding under rocks, logs, or debris during the day. While their sting can be painful and may cause serious symptoms, it is rarely fatal to healthy adults. The Arizona bark scorpion is also known for its ability to climb vertical surfaces, making it a common sight in homes and gardens.
