See this bug in the Encyclopedia

Natural Habitat

Damp environments, leaf litter, under tree bark, and indoors in bathrooms or kitchens near drains and books.

Diet & Feeding

Carnivorous; they eat small arthropods like moth fly larvae, carpet beetle larvae, booklice, ants, mites, and small flies.

Behavior Patterns

They use pincer-like pedipalps to capture prey. Many species engage in 'phoresy,' where they hitch a ride on larger flying insects to move to new locations. They do not have a stinging tail like true scorpions.

Risks & Benefits

Highly beneficial to humans as they act as natural pest control by eating common household nuisances. They are harmless to humans and pets, as they lack a stinger and their pincers are too small to break skin.
