Is the Klamathweed beetle a pest?
Order: Coleoptera Family: (Leaf Beetles) Chrysomelidae “Chrysolina quadrigemina” and “C. hyperici” If you check your local University Extension service they should have a bulletin on the subject. It was introduced to control the Klamathweed in Southern Oregon and Northern California which was not only crowding out desirable range plants needed for cattle but was also poisonous to the cattle. The beetle has effectively suppressed the weed.
