Western Conifer Seed Bug

Coniferous forests, but frequently enters buildings and homes during fall and winter to seek shelter.

Feeds on the developing seeds and cones of various coniferous trees (pine, Douglas fir, etc.) using its piercing-sucking mouthparts.

They are leaf-footed bugs known for the flattened, leaf-like expansions on their hind legs. They are strong fliers and produce a buzzing sound when in motion. They often congregate on sunny walls in autumn before seeking indoor overwintering sites.

Generally considered a nuisance pest when they enter homes; they do not bite humans, sting, or cause structural damage. However, they can emit a pungent defensive odor if handled or crushed. In ecosystems, they can reduce the seed yield of timber trees.
