Collections of trombiculid mites were carried out on Teuri Island in northwestern Hokkaido, Japan. A total of 200 trombiculid mite larvae belonging to three genera and five species (Neoshoengastia shiraii, Leptotrombidium pallidum burnsi, Leptotrombidium intermedium, Neotrombicula tamiyai, Neotrombicula teuriensis) were collected from seabird nests and field rodents. Of these, 195 mites were found in the soil of Cerorhinca monocerata nests and the most abundant species was N. shiraii (n=175), followed by L. pallidum burnsi (n=18). These two species are known to infest birds. C. monocerata was considered to be an important host for these trombiculid mites on this island. This is the first report on trombiculid mites from Teuri Island.
