House Centipede Scutigera coleoptrata

The (European) House Centipede has 14-15 pairs of legs (one on each body segment), the final pair sticking out at the tail like back antennae. It grows to some 25-35mm long.

They have spread worldwide to live in crevices in human housing, hence their name, where they are mainly nocturnal and beneficial, preying on spiders, bed bugs, silverfish and other unwanted insects and mites.

The double-headed centipede: a deliberate ploy so that predators don't know which end is the head.
