Larvae feed on plant roots, but a species list is not well known. Adults are found on wild and cultivated roses. When numbers of adults are large, the beetles damage roses by feeding on buds and flowers. Control Control is the same as for the rose chafer. Scouting Rose chafers are generally found in areas with sandy soil.
Adults feed on rose flowers and foliage.
The larvae feed on the roots of grasses, alfalfa, or clover sod. Inspect your plants for skeletonized leaves and adult beetles. While rose chafers can be numerous, hand pick if infestation is light. However, the beetles are quite mobile and new beetles may replace those killed by insecticides. Avoid spraying flowers so as to not kill bees.
