Abstract: Native 'Ohi'a trees (Metrosideros polymorpha) were sampled for mites at
two natural area reserves on Kaua'i Island, Kui'a and Hono O Na Pali. Ninety
samples of leaves, flowers, bark, leaf litter, and soil under the 'Ohi'a canopies
were taken. Mites were extracted with use of Berlese-Tullgren funnels. One
hundred sixty-four species were found, with the suborder Prostigmata having
the greatest number of species (74), followed by Mesostigmata (43), Oribatida
(43), and Astigmata with the least (4). Leaf litter, leaf litter with soil, and bark
have the most species, composed of predaceous mesostigmatic and prostigmatic
mites, but a certain amount of overlap of mite species between the leaf litter and
soil habitats was observed. The predominance of Collembola in the soil and
litter samples indicates a stable food source for the predaceous mites, partly explaining
the high number of mites in those habitats. Oribatid mites were collected
from leaves, but the species composition differs from that on flowers and
litter. Preliminary residency status of identified taxa shows 12% endemic, 17% adventive, and 71% of unknown status.
