This pest has the ability to destroy roses and grapes while adults are 1/2 inch-long metallic green and bronze beetles best know for their row of white tufts on the side below its wing covers. The larvae (immature stages), which also have white grubs can be seen from late summer through winter until about June when they emerge as an adult.
