Found a Pseudoscorpion exploring the wall this morning! After its photo shoot, I placed it outside in some leaf debris. It was about 3/16" or 5mm head to tail.
From Wikipedia: Pseudoscorpions, also known as false scorpions or book scorpions, are small, scorpion-like arachnids belonging to the order Pseudoscorpiones, also known as Pseudoscorpionida or Chelonethida. Pseudoscorpions are generally beneficial to humans since they prey on clothes moth larvae, carpet beetle larvae, booklice, ants, mites, and small flies.
