The striped bark scorpion (Centruroides vittatus) is an extremely common scorpion found throughout the midsection of the United States and northern Mexico; indeed, it is perhaps the most frequently encountered scorpion in the U.S.

[edit] Appearance and behavior
A medium-sized scorpion that is rarely longer than 60 mm(up to around 7cm), it is easily identified by two dark, longitudinal stripes on its carapace, with a dark triangular mark on its head. There are minor variations on this theme, however; specimens that are lighter-colored and lack the characteristic stripes have been described as separate species in the past.
Like many scorpions, C. vittatus is primarily a nocturnal insectivore. They are highly adaptable, and can be found almost anywhere with plenty of crevices in which to hide or hunt; these include forests, rocky areas, and buildings, where they can be a frequent indoor pest. The species does well in captivity.
Noted for their complex courtship behavior, their long breeding season runs from autumn through early summer; after an eight-month gestation, they give live birth to a brood of as many as 50 young.
[edit] Human significance
Though not aggressive, the scorpion's close association with humans makes envenomation relatively common. The sting can be extremely painful. For some, the worst passes in 15-20 minutes, but not uncommon to remain very painful with numbing sensations for 2-3 days. Fatalities are rare, and due to anaphylactic shock rather than the venom itself. Reported direct deaths are controversial. Sting victim should contact poison control.
