Abstract
Phoretic oribatid mites are recorded from specimens of 31 insect species, mostly passalid beetles. Mites were predominantly of the families Mesoplophoridae, Oppiidae and Oribatulidae. The former attaches by grasping a hair between the aspis and genital plate. A degree of attachment site specificity, but not host-species specificity, is exhibited by certain mites.
