Walnut twig beetles tunnel into branches and trunks of walnut (Juglans) where they create galleries for mating and reproduction. In association with a canker producing fungus, Tthey cause a disease known as thousand cankers disease. This tree is in downtown Davis, Calif. (Photo by Kathy Keatley Garvey)
