Leaf-footed bug (likely western conifer seed bug)

Coniferous forests, gardens, and buildings near pine, fir, spruce, or other conifers; often enters homes in autumn.

Adults and nymphs pierce developing conifer seeds and cones, sucking plant juices. They may also feed on fruits and other plant material.

Typically solitary and active from spring through autumn; adults seek sheltered sites to overwinter, sometimes aggregating indoors. They emit a strong odor when disturbed.

Harmless to people and not venomous, though its odor is unpleasant and it can damage conifer seeds or young cones. It is generally a minor garden or forestry pest.
