Octotemnus glabriculus

(Gyllenhal, 1827)

Octotemnus glabriculus is a minute tree-fungus beetle in the Ciidae. It is a fungivore that feeds on the bracket fungus Coriolus versicolor. Its feeding activity significantly reduces the fungus's reproductive by damaging the spore-producing hymenium. The occurs across Europe and Northern Asia, including Kazakhstan.
