Genus Lepisma is a scientific name given to a type of small silverfish that is characterized by elongated bodies and three long tail-like structures at their rear. There are several synonyms for Genus Lepisma, including Leposoma, Thysanura, and Lepisma saccharina, among others. These synonyms are used interchangeably to describe the same species of silverfish, which is commonly found in damp and humid environments such as bathrooms, basements, and garages. Genus Lepisma is not harmful to humans or pets, but can be a nuisance when they infest homes and buildings, feeding on starchy materials like paper and wallpaper paste. Regular cleaning and proper ventilation can help prevent infestations of these small, silver-colored insects.
