Monotomidae is a family of beetles in the superfamily Cucujoidea. The family is found worldwide, with approximately 240 species in 33 genera. The ecological habits of the family are diverse, with different members of the group being found under tree bark, in decaying vegetation, on flowers and in ant nests. Their ecology is obscure, while at least some species are mycophagous, feeding on the fruiting bodies of ascomycete fungi, Rhyzophagus are predators on bark beetles (includings, eggs, larvae and young adults) and possibly Phoridae larvae, with the larvae of some species also being mycophagous.
