A pseudoscorpion, false scorpion or book scorpion, is an arachnid belonging to the order Pseudoscorpionida, also known as Pseudoscorpiones or Chelonethida. They are generally beneficial to humans since they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies. They are small and inoffensive, and are rarely seen due to their size. They have a flat, pear-shaped body and pincers that resemble those of scorpions. They range from 2 to 8 millimetres ( to in) in length. The largest known species is Garypus titanius of Ascension Island at up to 12 mm ( in).
