The White-Spotted Sawyer Beetle can be found in most evergreen forests across the continent. Their larvae bore into the trees.
One white spot at the top of the elytra (wing covering) marks this black beetle. Smaller white speckling may be visible on the eltyra (wings) as well, but it may be absent. Females have more of white speckling than males. Members of this family have a spike, or a protrusion, coming out of each side of the 'throat'. The White-Spotted Sawyer Beetle is a type of Long-Horned Beetle so one can expect them to have extraordinarily long antennae ('horns'). This species' antennae can be up to 3 times longer than their actual bodies.
This beetle prefers conifer trees like pine, spruce, fir and can be found in evergreen forests. They may also be found in areas where branches are freshly cut, like lumber yards. Females lay eggs on the tree and when the larvae hatch, they bore into the wood of dead or dying trees. Adults are active in the daytime and eat twig bark.
