Biology. Three females of this species have been collected from the nest of a bumble bee (Baker, 1949). This record is probably accidental because it has not been confirmed and this type of habitat is unusual for the genus. On the other hand, there are mite genera (Kuzinia, Parasitellus) that occur both in rodent and bumble bee nests. This may be explained by the fact that bumble bees often construct their nests in borrows of rodents.
