Lepisma saccharina, frequently called a silverfish or fishmoth is a small, wingless insect in the order Thysanura. Silverfish are always wingless and are silvery to brown in colour because their bodies are covered with fine scales. They are generally soft bodied. 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.
