The life cycle of water mites is complex and includes the egg, larva, protonymph, deutonymph
, tritonymph, and adult.
Up until now, 23 species have been described in this group, one of which is known only from the deutonymph
When it found a female deutonymph
in the quiescent stage it settled very close to it and waited for its moulting and also helping to cast off the moulting skin.

represented the last instar before attaining the adult status.
Each phoretic deutonymph
attaches to its host by means of an anally secreted fluid that solidifies in the air into a supportive, stem-like structure called a pedicel.
or hypopus is a developmental instar of mites, and in H propus it is one of 5 juvenile stages including the prelarva, larva, protonymph, deutonymph
, and tritonymph.
In the Astigmata, only one of the life stages, the deutonymph
(sometimes termed a hypopus), exhibits phoretic behavior.
Nesochernes gracilis norfolkensis Beier 1976: 2 males, 2 females, 1 tritonymph, 1 deutonymph
, 1 protonymph from Filmy Fern Walk, 29'01'S, 167[degrees]57'E, Norfolk Island National Park, Norfolk Island, Australia, 30 November 1984, litter under Araucaria heterophylla, TA.
Paratypes: 1 male (CNANT0186), 1 female (CNANT0187) deposited in CNAN, 1 female (CAAMS-PS001), 7 tritonymph, 2 deutonymph
, and 1 protonymph, with same data as holotype (CNAN).
Nymphs: Much like adults, but trichobothrial patterns as follows: tritonymph with 14 on fixed finger and 8 on movable finger; deutonymph
with 9 on fixed finger and 6 on movable finger; and protonymph with 3 on fixed finger and 1 on movable finger.
