This has been recorded as playing a role in predation; the centipede suspends itself in the air and swings back and forth to capture prey.
A similar behaviour has been recorded in ordinary meetings, wherein each centipede grasps the other's trunk with its ultimate legs.
[2] During mating, Scutigera coleoptrata raise and lower their ultimate legs, along with their antennae.
[3] Members of the genus Alipes stridulate their leaf-like ultimate legs, probably as a way to warn off predators.
[2] The ultimate legs of Rhysida immarginata togoensis emit a faint creaking or squeaking sound when detached and bent.
