White-spotted Sawyer

Natural Habitat

Coniferous forests, specifically in areas with dying or recently felled pine, fir, and spruce trees.

Diet & Feeding

Larvae bore into and feed on the wood of dead or dying conifers; adults feed on the needles and bark of living twigs.

Behavior Patterns

They are active during the day and are strong fliers; they are often the first to colonize trees after forest fires or logging activities.

Risks & Benefits

They risk degrading Timber value through larval tunneling, but benefit ecosystems by assisting in the decomposition of dead wood; they do not bite humans but are often mistaken for invasive species like the Asian Longhorned Beetle.
