Description: Many species of mite that live exclusively in decaying wood and subcortical environments have intricate relationships with bark beetles (Coleoptera: Curculionidae, Scolytinae) (e.g., in the genus Dendroctonus, Ips, Scolytus) (Lindquist, 1969; Moser, 1975; Hirschmann and Wisniewski, 1983; Karg, 1993). These mites depend on bark beetles or other subcorticolous insects for dispersal and introduction into appropriate living substrates. Mite communities associated with bark beetles can be large and complex, with multiple feeding guilds and trophic levels (Lindquist, 1969; McGraw and Farrier, 1969). However, because of the difficulty in observing subcorticular mites, very little is known about their biology and feeding behavior.
