Derodontus
tooth-necked fungus beetles
Derodontus is a genus of tooth-necked fungus beetles comprising approximately eleven described species. Members are mycophagous, feeding on fungi. The genus has a Holarctic distribution with species recorded from North America, Europe, and Asia. Derodontus macularis has been documented in well-preserved natural forest habitats in eastern Moravia, Czech Republic.
Derodontus unidentatus
Derodontus unidentatus is a species of tooth-necked fungus beetle in the family Derodontidae. It was described by Lawrence in 1979. The species is known to occur in North America. Members of Derodontidae are associated with fungal substrates, though specific ecological details for this species remain limited.
Laricobius erichsonii
Laricobius erichsonii is a small predatory beetle in the family Derodontidae, native to Europe and the sole European representative of the genus. It has been introduced to North America as a biological control agent for the balsam woolly aphid (Adelges piceae), with releases in eastern Canada since 1933 and in Oregon and Washington from 1957–1960. The species is one of the more numerous predators of A. piceae in its native range. It belongs to the widespread Holarctic group within Laricobius, characterized by an elongate body and transverse, fully explanate pronotum.
Peltastica
tooth-necked fungus beetles
Peltastica is a genus of small beetles in the family Derodontidae, commonly referred to as tooth-necked fungus beetles. The genus was established by Mannerheim in 1852 and includes at least two described species: P. tuberculata and P. amurensis. These beetles belong to the subfamily Peltasticinae and are associated with fungal habitats. The genus is rarely encountered and poorly known biologically.
