The Silverfish (Lepisma saccharina L.). - This little household pest is found in both Europe and in the U.S. It is silvery gray in color, usually less than half an inch long, and very active and hard to catch. Besides the two long cerci at the hinder end of the body it has a similar "caudal filament" giving the insect the appearance of having three "tails."
It prefers dark places and feeds on book bindings, starched clothing, or anything containing starch, and often loosens wall paper by feeding on the starch used to paste it to the wall.
The silverfish prefers moist to dry places like most of the group, though a related species, the fire brat (Thermobia domestica Pack.), lives in warm places near ovens, fireplaces, etc.
Starched clothing should not be stored where it is damp.
