Xyleborinus artestriatus
Xyleborinus artestriatus is a species of ambrosia beetle in the subfamily Scolytinae. Like other members of its genus, it is a fungus-farming beetle that excavates galleries in wood and cultivates symbiotic fungi for larval nutrition. The species has been recorded in North America, Australia, Oceania, and Southern Asia. Its specific ecological role and host associations remain poorly documented compared to better-studied congeners such as Xyleborinus saxesenii.
Xyloterinus politus
Polished Bark Beetle
Xyloterinus politus is a North American ambrosia beetle in the family Curculionidae, historically placed in Scolytidae. It is the sole species in the monotypic genus Xyloterinus. The species exhibits obligate mutualism with cultivated fungi, excavating galleries in hardwood and softwood trees where it grows and feeds on ambrosial fungi rather than wood tissue. Females initiate gallery construction and maintain fungal gardens; males do not excavate galleries and are excluded from active attacks. The beetle overwinters as an adult in old galleries and cradles.
