My son found this pseudoscorpion on our bathroom wall. I stuck it in the fridge for a few minutes to slow it down before photographing it, and then set it free.

Males maintain small mating territories, few centimeters in size. When a female enters the territory, the male initiates a mating dance and eventually deposits a spermatophore, which is then picked up by the females. Fecundity is 20–40 eggs. The development from egg stage into maturity takes 10 to 24 months and involves three molts; molting may involve building a silk nest. The total life span is 3–4 years.
