Klamath weed beetle
Chrysolina quadrigemina/hyperici: These foliage feeding insects have dramatically reduced the St. Johnswort problem in the Northwest and Pacific states. Damage to the foliage by larval feeding lowers root reserves, making it more difficult for the plant to survive harsh winter and/or dry summer conditions.
