Rose Chafers love to congregate and chip away at a rose bush's health and beauty, chewing up its blooms and leaves.
These small and slender members of the beetle family are a common pest usually associated with roses, but they do eat other types of plants as well. Rose Chafer larvae are equally adept at destroying plant life, including grass. The chubby white grubs attack grass blades from the roots, potentially ruining pristine turf. Adults prefer a menu that includes shrubbery, flowers and the foliage.
The Rose Chafer can be identified by its ivory-yellow appearance. Its elytra (wing coverings) are covered with short, soft hairs. The legs are darker in color than the body, almost brown. Its body is more slender than other Scarab beetles like the equally destructive Japanese Beetle. Other less pesky relatives include May and June Beetles.
One Rose Chafer is usually found in the company of other Rose Chafers. Together they quickly ruin a rose blossom by nibbling away at it and the foliage around it. They are difficult to remove thanks to those strong little legs. They use them to clutch onto the plant, so knocking them off may take some force. Many gardeners use chemical pesticides to prevent and remove Rose Chafers from their plants. Left unchecked, they can ruin a hedge in little time.

Size (Adult; Length): 7mm to 10mm (0.27in to 0.39in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Antennae: Beetles have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and mandibles (jaws).
Thorax: Holds the three pairs of legs as well as vital internal organs.
Elytron: One of two wing cases on a Beetle that protects its wings (plural: elytra).
Wings: Appendages used for flying and kept under the elytra until needed.
Abdomen: Houses organs related to circulation, reproduction, and excretion.
Legs: Beetles have three pairs of legs located at the thorax, numbering six legs in all.
