Specieswatch: No sting in the tail to the pest-munching book scorpion

It is mostly unnoticed because it is only 2-8mm (0.08-0.31in) long and hides from the light, hunting its prey at night. The book scorpion is said to have been first spotted by the Greek philosopher Aristotle when the tiny creatures were in his library. They were chomping up the book lice that were destroying his precious volumes by eating the vegetable glue that held the pages together.
