House Pseudoscorpion
Chelifer cancroides, the house pseudoscorpion, is a small pseudoscorpion species measuring 2.5–4.5 mm in body length with pedipalps extending to 7–9 mm. It is the most widely distributed pseudoscorpion species globally, occurring across North America, Europe, Africa, Australia, and the Caribbean. The species is strongly synanthropic, frequently found in human dwellings, barns, and beehives, but also occurs in natural habitats including under tree bark, in caves, and in bird nests. It is harmless to humans and preys on small arthropods.
