Ear mites are mites that live in the ears of animals. The most commonly seen species in veterinary medicine is Otodectes cynotis (Gk. oto =ear, dectes =biter, cynotis =of the dog). This species, despite its name, is also responsible for 90% of ear mite infections in felines.
The mite is 0.4 mm (0.016 in) in size, [2] approximately the size of a grain of salt, and can be seen with the naked eye. [5] It lives in the external ear canal of its host, and causes intense irritation leading to otitis externa. [2] The lifecycle of O. cynotis takes approximately three weeks. [1]
Each species of mite is usually only found on a single mammal species, whereas a mammal species can have several different species of demodecid mites living on it. [2] Many species of mites are restricted to very limited areas of their body, e.g. the Meibomian glands , the ear canal, the tongue etc.
Mites which colonize human skin are the cause of several types of itchy skin rashes, such as gamasoidosis, [51] rodent mite dermatitis, [52] grain itch, [53] grocer's itch, [53] and scabies; Sarcoptes scabiei is a parasitic mite responsible for scabies, which is one of the three most common skin disorders in children.

Demodex / ˈ d ɛ m ə d ɛ k s / is a genus of tiny mites that live in or near hair follicles of mammals. Around 65 species of Demodex are known. [2] Two species live on humans: Demodex folliculorum and Demodex brevis, both frequently referred to as eyelash mites, alternatively face mites or skin mites. [3] Different species of animals host ...
Dicrocheles phalaenodectes is a parasitic mite which infests the ear of certain species of Noctuid moths. [ 1 ] [ 2 ] They are notable in that only one ear is ever colonised, leaving one intact so that the host is still able to detect the sound from hunting bats .
Psoroptidia is a parvorder of the Acari group Astigma (or Astigmatina). [1] It comprises around 40 families, and apparently originated as parasites of birds, before a secondary radiation saw some taxa become parasites of mammals. [2]
Otoacariasis is a rare infestation of the ear canal, which can be caused by different types of mites and ticks. [ 14 ] Most commonly N. cati as a cause of Notoedric mange may be diagnosed from a skin scraping sample with a direct microscopic identification of the mite, because there are a large number of mites present on the skin.
