Acarodomatia (singular Acarodomatium) (Latin: Acari - mites, domus - dwelling), are tussocks of hairs or nonglandular trichomes located in pits situated in major leaf vein axes of many plant species, occupied and caused by predatory and mycophagous mites.^[1]

Acarodomatia have also been described from lizards where they are commonly called "mite pockets".^[2] These cavities or skin folds are usually located around the neck or behind the legs and occupied by chiggers. Their function is debated,^[3] but they are thought to distract mites from damaging or blocking important skin surfaces such as the tympans.^[4]
