Camponotus laevigatus or the giant carpenter ant is a species of carpenter ant native to eastern Canada, the United States, and Mexico. Workers measure between 7 and 13 millimeters in length. General coloration is shiny black with a blue tint; this is where its specific name (laevigatus) comes from, meaning smooth or slippery. The body is covered in short white hairs. The species, which is primarily diurnal, tends to make its nests by hollowing out redwoods. It feeds on the pupae of the western spruce budworm.
