The larvae of leaf-footed pine seed bug feed on the developing cones and seeds of various species of pine. Their feeding does not damage pine trees but it does diminish seed production, and these insects are a problem for conifer nurseries. They commonly invade houses to overwinter but do no damage there-- they don't eat wood, fabrics, feathers, or stored food, and do not bite.
