They are small, ather, ametabular insects, with compound eyes and, often, ocelli; some species can even reach 20 millimeters in length. The mouthparts are chewing. They have a tapered body, flattened and covered with light gray scales. they have long antennae and typically have three threadlike appendages with bristles at the end of the abdomen. The lateral filaments are cerci, while the median filament is the extension of the last abdominal segment (paracerco). The Tisanuri live mainly in the ground, among the plant debris, and under the stones; some species inhabit the
domestic environments in which they can cause damage. Among these we mention the silverfish, whose most common representatives are Lepisma saccharina and Thermobia domestica Pack which feed on flour, sweet substances, fabrics, paper (sometimes they damage books, etc.).
