Scutigera coleoptrata above and below is found in Europe and North America, usually around human habitations, sometimes like a spider it is found in the bath, but mostly it is found in the soil and leaf mould. It is completely harmless as its jaws are neither big enough nor strong enough to bite us. It does bite and eat mosquitoes, though, so could be considered a help in the home. All the centipedes of this type can run very fast.
