Gnathotrichus materiarius

Gnathotrichus materiarius, the American utilizable wood bark beetle, is an ambrosia beetle in the family Curculionidae.[1][2][3] It is native to North America,[1] but has been introduced to several European countries.[4][5] 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.[6]
