Western Conifer Seed Bug

Coniferous forests and woodlands; often enters homes in autumn seeking shelter for winter.

Nymphs and adults feed on the sap of developing cones and seeds of various coniferous trees.

Diurnal insects that are strong fliers; they produce a distinct buzzing sound when flying and a foul odor when disturbed as a defense mechanism.

Harmless to humans as they do not bite or sting and do not cause structural damage; considered a nuisance pest in homes and can reduce seed crop yields in conifer orchards.
