Jewel Beetle (specifically the Golden Buprestid or similar iridescent wood borer)

Coniferous forests and woodlands throughout western North America; often found on Douglas-fir, pine, and spruce trees.

Larvae are wood-borers that feed on the sapwood and heartwood of dead or dying conifers; adults feed on needles and tender bark.

Diurnal and highly active in sunny weather; they are known for an incredibly long larval stage, sometimes remaining inside timber or finished lumber for decades before emerging.

Environmentally beneficial as decomposers that help break down dead wood; however, they are considered a minor nuisance if they emerge from structural wood inside homes.
