Gnathotrichus materiarius, the American utilizable wood bark beetle, is an ambrosia beetle in the family Curculionidae.[2][3][4] It is native to North America,[2] but has been introduced to several European countries.[5][6] It lives in symbiosis with the fungus Endomycopsis fasciculata, which adult beetles inoculate into the wood of host trees - the fungus then acts as the primary food source of the larvae and adults.[7]
