Four-lined Silverfish

Ctenolepisma lineatum, the four-lined silverfish, is a species of silverfish of the order Zygentoma. It is rather stouter and less shiny with all the appendages (antennae and 3 "tails") being noticeably longer. The abdomen is often marked with dark brown lines.

This species is native to southern Europe but is now found throughout most of the world, aside from polar and cooler temperate regions (e.g. the British Isles), as an accidental introduction. It is found both indoors and outdoors and can be a nuisance pest.
