Order Zygentoma is also known as Order Thysanura. They are distributed worldwide. About 320 species have been described. The common names for the species are silverfish and firebrats. They get their name from the silver scales on some of the species. Their distinguishing characteristic is their three caudal filaments. They do not have wings. Silverfish are about two to twenty millimeters in length. They can either be found indoors amongst books or outdoors under stones, bark, or fungi. Outdoor silverfish feed on plant materials and indoor silverfish feed on wallpaper glue or book binding paste. Young silverfish will usually molt between twenty to seventy times. The molts only make them larger in size. They live for about one to four years. They can be found in the fossil record as far back as the Late Carboniferous.
