The eggs then hatch into an immobile pupoid, which then molts into an instar. At the instar stage, the millipede has four developed rings (segments) and three pairs of legs between the rings. Behind the mobile rings are two to three immobile rings which are then followed by the telson or posterior-most segment of the body, like a tail. By the next molt the immobile rings will all have pairs of legs. (Blower 1985)
