The White-spotted Sawyer Beetle can be found near most evergreen forests, the breeding grounds for their tree-boring larvae.
A single white spot at the top of the elytra (wing coverings) adds a pop of color to this black beetle. Smaller white speckling may be visible on the eltyra of some individuals as well, but it may also be absent. Females are more likely to have this white speckling than males. The White-spotted Sawyer Beetle has a spike, or a protrusion, coming out of each side of its collar area. This species is a type of Long-horned Beetle so extraordinarily long antennae (also called 'horns') reach out far beyond the head. In fact, their 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 evergreen branches are freshly cut, like lumber yards. Females lay eggs on the tree and when the larvae hatch, they bore deeply into the wood of dead or dying trees. Adults are active in the daytime and eat twig bark.
Scientific Name: Monochamus scutellatus
Size (Adult; Length): 18mm to 25mm (0.70in to 0.98in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
Abdomen: Houses organs related to circulation, reproduction, and excretion.
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
