Striped Bark Scorpion Missouri Department of Conservation

Striped bark scorpions are pale yellowish brown, usually with two lengthwise dark stripes on the abdomen. This is the only species of scorpion in Missouri. It occurs in glades and other dry, warm, rocky areas, and sometimes in buildings and shelters and under piles of wood, brush, or garbage. Most people are familiar with the overall scorpion shape: a flattened, elongated oval body; the pair of front appendages with pincers; four pairs of walking legs; and a long, curling tail that ends in a bulbous segment tipped with stinger. This species is distinguished, among other things, by a dark triangle is on top of the head. Young striped bark scorpions are pale yellowish brown, usually with two broad lengthwise dark stripes on the abdomen (the back); older scorpions are uniform dark brown with the stripes faint or lacking. A scorpion has a pair of eyes in the middle of its back, as well as two to five additional pairs of eyes along the front edge of its body. Even though they have a lot of eyes, scorpions have poor vision. They make up for this by having tiny sensitive hairs on their pinchers that help them detect motion. In addition, scorpions have strange comblike structures called pectines on their undersides, which are unique to scorpions. The pectines are sensitive to touch, to ground vibrations, and perhaps even to sound.
