Pseudoscorpion
Chelifer cancroides
- Order & Family
- Order: Pseudoscorpiones, Family: Cheliferidae
- Size
- 2 to 8 millimeters (0.08 to 0.31 inches)
Natural Habitat
Found globally in leaf litter, under bark, in caves, and frequently in homes, especially in bathrooms or libraries.
Diet & Feeding
Carnivorous; feeds on small arthropods like silverfish, mite, booklice, and fly larvae using venom-filled pincers.
Behavior Patterns
Solitary and nocturnal hunters that use phoresy (hitching rides on larger flying insects) to travel to new locations; they produce silk from glands near their jaws to build cocoons for molting or wintering.
Risks & Benefits
Completely harmless to humans and pets as they lack a stinger and their pincers cannot pierce skin; highly beneficial to ecosystems and homes by controlling populations of carpet beetles and booklice.
