Lepisma saccharina, frequently called a silverfish or fishmoth is a small, wingless insect in the order Thysanura. Its common name derives from the animal's silvery light grey and blue colour, combined with the fish-like appearance of its movements, while the scientific name indicates the silverfish's diet of carbohydrates such as sugar or starches. Silverfish are a cosmopolitan species, found in Africa, America, Europe, Australia, Asia and other parts of the Pacific. They inhabit moist areas, requiring a relative humidity between 75% and 95%. In urban areas, they can be found in basements, bathrooms, garages, closets, beds, pillows, and attics. The reproduction of silverfish is preceded by a ritual involving three phases, which may last over half an hour. In the first phase, the male and female stand face to face, their trembling antennae touching, then repeatedly back off and return to this position. In the second phase the male runs away and the female chases him.
