Both ambush and stalk modes of capture have been documented. Pseudoscorpions, like most arachnids, partially digest their food externally. Once captured in the chelae, venom is injected into the prey item to immobilize it quickly. The prey's body is then passed to the chelicerae where it is pierced and exposed to secreted digestive enzymes. The dissolved body juices are then taken into the body where further digestion occurs.
Pseudoscorpions have a typical arachnid reproductive pattern.
Prior to mating the adults often exhibit a form of courtship, including posturing, various dancing steps, and grasping with the pedipalps. Subsequently, the male produces a stalked spermatophore which he attaches to the substrate. The female acquires the sperm from that structure, a form of indirect sperm transfer. The fertilized eggs are transferred to a secreted brood pouch where they remain during hatching and development to the protonymphal stage. Two additional nymphal stages, deutonymph and tritonymph, must be attained via molting before the final development into the adult form.
