Striped Bark Scorpion

The Striped Bark Scorpion (Centruroides vittatus) is a very common arachnid that is found across the Southwestern United States.  Those of you who live in Austin, San Antonio, and other areas where the environment is prairie or desert-like will probably recognize this animal.

The venom of the Bark Scorpion is a complex mixture of more than 100 neurotoxins which paralyze its prey.  One of these toxins is 1,000 times more deadly than cyanide.  The sting of this animal is extremely painful, but usually not fatal.  However, there are a few rare cases where humans have died from anaphylactic shock triggered by the scorpion’s powerful venom.
