Development And Growth

Most mites develop through an egg stage, a 6-legged so-called 'larval' stage and one, two or three 8-legged nymphal stages: protonymphs, deutonymphs and tritonymphs, respectively. There are notable exceptions, for example: (a) in the superfamily Eriophyoidea there is no larval stage; also, the adults and nymphs have just two pairs of legs; (b) in the family Tarsonemidae (order Prostigmata) the 6-legged larva, when fully fed, typically develops to adulthood through a sedentary and non-feeding, pupa-like (quiescent nymphal) stage that is retained within the bloated, cast-off skin of the larva - this is reminiscent of the puparium found in certain Diptera.
