The life cycle of water mites is complex and includes the egg, larva, protonymph, deutonymph, tritonymph
, and adult.
The deutonymph 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
Stages in the life cycle of Dermatophagoides include egg, larva, protonymph, tritonymph
, and adult.

inquilinus are deposited in the Geneva Natural History Museum, Switzerland (MHNG) (1 [female], 1 [male] and 1 tritonymph
), the Instituto de Ciencias Naturales, Universidad Nacional de Colombia, and in the Museo Javeriano de Historia Natural Lorenzo Uribe, Pontificia Universidad Javeriana, Bogota, Colombia (2 [female], 2 [male] , 2 tritonymphs

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.
This undescribed species is known only from 23 specimens (1 [male], 3 [female][female], 11 TT, 5 DD, 3 PP) collected in four of the five nests sampled; however, all specimens were on the "cover" of the nests except for one tritonymph
found in the "green chamber".
boneti (1 larva, 1 tritonymph
and 2 adult males) stored in ethanol (70%) were dehydrated in graded ethanols, critical-point dried and coated with gold-palladium.
Semeiochernes armiger (Balzan 1892): 6 males collected in January 2006 either as adults (n = 3) or as tritonymphs
that molted to the adult stage in the laboratory (n = 3).
hunted cooperatively with the mother (3 in 42 observations of the mother hunting), or without the mother (n = 14 records during 50 observation sessions).
