Arizona Bark Scorpions
The Arizona bark scorpion (Centruroides sculpturatus) is known for its venomous sting, which can be lethal, especially for small children and elderly people. This scorpion species grows up to 7 cm, or 3″ long. They are light brown to brownish yellow in color, with dark lengthwise bands. Their pincers are elongated and thin, unlike other scorpions that have thick, lobster-like pedipalps. Their tail is also slender and yellow to light brown in color.
The Arizona bark scorpion can be found in the Southwestern U.S. It is especially widespread in most parts of Arizona. Small populations of this scorpion have been observed in southeastern California and southern Utah. They can also be found throughout the Baja Peninsula and western Mexico.
The bark scorpion can climb walls, trees and other objects with a rough surface. It is not capable of climbing glass and smooth surfaces.
These scorpions prefer to dwell in areas that can support insects, and other small prey species. These areas must also have sufficient amounts of moisture and humidity.
The feeding habits are similar to that of other scorpions. The Arizona bark scorpion prefers to hide and will cling to almost anything. It is nocturnal and feeds on crickets and other insects that happen to pass by its burrow. Bark scorpions are not aggressive and would rather hide or run when confronted by an enemy.
Its venom can cause severe pain. Symptoms such as numbness, frothing at the mouth, difficulties in breathing, muscle twitching and convulsions can be observed on a human that has been stung. Death is rare, but possible in some cases. The sting may be more dangerous for small children and the elderly.
