Western Conifer Seed Bug

Found in coniferous forests, woodlands, and frequently invades homes during autumn to overwinter.

Herbivorous, feeding on developing seeds and cones of conifers using piercing-sucking mouthparts.

Active flyers during warm months, emitting a pungent defensive odor when disturbed. They aggregate in large numbers on building exteriors in autumn seeking warmth.

Harmless to humans as they do not bite, sting, or transmit disease, but they can be a severe agricultural pest to seed orchards and a nuisance household invader.
