Lithobius forficatus, most commonly known as the Brown Centipede (or Common Centipede), is a common European centipede of the family Lithobiidae, although its distribution is not exclusive to Europe. It is between 18 and 30 mm long and up to 4 mm broad and is a chestnut brown colour.
It is similar to a variety of other European lithobiid centipedes, particularly the striped centipede, Lithobius variegatus, but L. forficatus does not have stripes on its legs. Like most lithobiids, it is found in the upper layers of soil, particularly under rocks and rotting logs. This species can be fairly easily identified by an experienced myriapodologist by its reaction to being revealed, which is to run extremely quickly for cover. This is different from many of the other species of large lithobiid, which tend to be less extreme in their evasion behaviour.
