Two major lineages of Acariformes are recognized, the Sarcoptiformes (Oribatida and Astigmata) and Trombidiformes (Prostigmata).
The annotation of these mitochondrial genomes indicated unique gene orders, highly rearranged in comparison to other Trombidiformes mites (Fig.

Drifting densities of all invertebrates, Trombidiformes, and organic matter were square-root transformed and drifting densities of Baetis, Orthocladiinae, and Hydropsyche were log (x + 1) transformed to meet assumptions of homogeneity of variance (Zar, 1999).
The five most common drifting taxa (excluding terrestrial insects) were Baetis (Ephemeroptera: Baetidae), Simulium (Diptera: Simuliidae), Trombidiformes, Orthocladiinae (Diptera: Chironomidae), and Hydropsyche (Trichoptera: Hydropsychidae); composing 45, 13, 13, 9, and 3% of the total, respectively.
Densities of drifting Orthocladiinae, Trombidiformes, and Hydropsyche showed increasing patterns with increasing numbers of hikers, but were more variable when numbers of hikers were intermediate (Figs.
This edition indicates there are 6 orders (including the Opilioacaridida, Holothyrida, Ixodida, Mesostigmata, Trombidiformes, Sarcoptiformes) within the subclass Acari.
