Xyloterinus

[1][2][3] It is native to North America where it infests both hardwood and softwood trees, as well as stacks of logs.

[4] This beetle is native to eastern North America, where it is present in both Canada and the United States.

[4] Host trees include Acer, Alnus, Betula, Carya, Castanea, Fagus, Fraxinus, Picea, Pinus, Quercus, Tsuga, and Ulmus.

[5] After mating, the adult female tunnels into the bark, creating a gallery up to 45 mm (1.8 in) long in the sapwood.

[7] The eggs hatch within about fourteen hours, and the larvae feed on the mycelia and spores of the fungus, enlarging the cradle as they grow.
