Oribatida (formerly Cryptostigmata), also known as moss mites or beetle mites,[1] are an order of mites, in the "chewing Acariformes" clade Sarcoptiformes. They range in size from 0.2 to 1.4 millimetres (0.008 to 0.055 in).[1]

Oribatid mites generally have low metabolic rates, slow development and low fecundity.[1] Species are iteroparous with adults living a relatively long time; for example, estimates of development time from egg to adult vary from several months to two years in temperate forest soils.[1] Oribatid mites have six active instars: prelarva, larva, 3 nymphal instars and the adult.[1] All these stages after the prelarva feed on a wide variety of material including living and dead plant and fungal material, lichens and carrion; some are predatory, but none is parasitic and feeding habits may differ between immatures and adults of the same species. Many species have a mineralized exoskeleton.[2][3]

The Oribatida are of economic importance as hosts of various tapeworm species, and by increasing the breakdown of organic material in the soil, in a similar manner to earthworms.[4]


Oribatida is divided into the following taxa:[5]
