    Rose Chafer - (Macrodactylus subspinosus)

    Rose Chafers love to congregate on their namesake and chip away at a rose bush's health, eating its blooms and leaves..

    Staff Writer (1/30/2014): These small and slender members of the beetle family are a common pest usually associated with roses though they do eat other types of plants as well. The Rose Chafer larvae are equally adept at destroying plant life, including grass. The chubby white grubs attack grass blades from the roots. Adults prefer a menu that includes shrubbery, flowers and the foliage.

    The Rose Chafer can be identified by its creamy 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 beetles of the Scarabidae family. Relatives include May and June Beetles and the equally destructive Japanese Beetle.

    Rose Chafers are usually found in the company of many other Rose Chafers. Together they can quickly ruin a rose blossom. They eat away at it and the foliage and are difficult to remove. They use their legs to clutch onto the plant and knocking them off may take some force. Many gardeners use chemical pesticides to prevent and remove infestations.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
