Western conifer seed bug

Conifer forests and seed-bearing trees; often enters buildings in autumn to overwinter.

Feeds by piercing developing seeds and cones of conifers, including pine, fir, and spruce.

A long-legged true bug with flattened, leaf-like expansions on its hind legs. Adults overwinter in sheltered places and may gather indoors; they do not establish indoor breeding populations.

Harmless to people and homes, though it can emit an unpleasant odor when disturbed. It can reduce conifer seed production, but is not generally a serious forest pest.
