Anyone who lives in an old stone French house is undoubtedly living with scuties. Or as they are more properly known, Scutigera coleptera, the Common House Centipede.
They are fearsome looking beasts, with 15 pairs of very long banded legs and an even longer pair of antennae. They live in the dark, humid crevices, coming out at night to hunt spiders, silverfish, cockroaches and fly larvae. They are venomous, with the first pair of legs modified into fangs. If they manage to bite you, it is painful and the flesh surrounding the wound swells and goes purple, like some spider bites do.
Immature scuties have fewer legs, starting off with just 4 pairs. As they grow they moult their exoskeleton, and each time, they gain a few more pairs of legs until they are adult, after the fifth moult. They move very fast. The hindlegs are twice as long as the front legs, which allows them to cross over and beyond, preventing the scutie from ending up in a tangled ball of legs.
