A large order (or subclass) of small arachnids which comprises the mites and ticks. They are distinguished by an apparent lack of body divisions.
- ‘Over 45,000 arthropods were collected from 55 plants (5 plants from each of 11 sites), dominated numerically by Acari and Thysanoptera.’
- ‘In addition to Diptera, CI has since been found to be a Wolbachia-induced trait in a wide diversity of arthropod orders, including Acarina, Coleoptera, Homoptera, Hymenoptera, Isoptera, Lepidoptera, and Orthoptera.’
- ‘The communities were dominated numerically by Thysanoptera (leaves and stalks) and Acari, but other taxa including Heteroptera and Coleoptera were also relatively common.’
- ‘For example, red velvet mites, which can be up to 0.4 inches long - among the giants of the Acari - can be seen hunting on the ground or on tree trunks.’
- ‘The second most common taxon was Acarina, which was most common in pond-side arrays.’
- ‘Botfly larvae often attack nestlings as do other nest parasites (Hemiptera, Psammolestes, Triatoma and Acarina).’
- ‘The samples were dominated numerically by the Thysanoptera and Acari, accounting for over 90% of the arthropods from both leaf and stalk material.’
- ‘The Acari (mites and ticks) are closest related to the Ricinulei or the ‘hooded-tickspiders,’ a group of nontoxic arachnids.’
- ‘Many other members of the Acari are microscopic, like this unidentified mite photographed with UCMP's Environmental Scanning Electron Microscope.’
- ‘The examination of 278 hosts of 16 species yielded 11,030 ectoparasites representing six families of Insecta and eleven families of Acari.’
- ‘Nothing is known about gene order in other lineages of Acari.’
- ‘Among the 11 extant orders of arachnids, Araneae and Acari (ticks and mites) are by far the most species rich.’
- ‘The Chelicerates include among their number both the tiniest (the microscopic Acari or mites) and the hugest (the giant Paleozoic Eurypterida) of all the Arthropoda.’
- ‘Parthenogenesis-inducing Wolbachia are restricted to species with haplodiploid sex determination, as occurs in the arthropod groups of Hymenoptera, Thysanoptera, Coleoptera, and Acari.’
Modern Latin (plural), from acarus, from Greek akari ‘mite’.
