Pseudoscorpion

Leaf litter, under bark, in caves, or inside homes (often in bathrooms or libraries)

Carnivorous; feeds on small arthropods like booklice, mites, and fly larvae

They use their pincer-like pedipalps to catch prey and sometimes hitch rides on larger insects (phoresy) to move to new locations

Beneficial to ecosystems and homes as they eat household pests like booklice and mites; they are harmless to humans and do not sting or bite
