The Common Striped Scorpion, Centruroides vittatus, is widely
distributed throughout the southwestern United States. It is a member
of the Bark Scorpion group (Centruroides spp.) and is the primary
scorpion that infests homes in Texas and Oklahoma. Scorpions will sting
if disturbed. While the sting is not generally dangerous it is painful
and is followed by local swelling and discoloration.
The Striped Scorpion gets its name from two parallel longitudinal
dark stripes on the top of its abdomen. This scorpion, about 3 inches
long when mature, has four pairs of legs and a five segment posterior
terminating at the sting. The scorpion hides during the day under loose
bark, rocks, leaves, and tools left in the yard or any place that
provides shelter, moisture and potential prey. In areas infested with
scorpions, special care must be taken when moving objects on the
ground. They are known to infest homes and commercial facilities,
living in attics, walls, and crawl spaces. Scorpions are predators
only, feeding primarily on insects or other arachnids, coming out to
hunt at night. Scorpions have very poor vision, primarily depending on
a sense of feel for movement and hunting. Feeling is accomplished using
feathery comb-like organs called pectines, located on the underside of
a scorpion’s body between the last pair of legs. These pectines are
used to determine what kind of surface the scorpions are on, in
detecting low impulse vibrations, and for chemoreception.
