Macrodactylus subspinosus is a North American beetle of the family Scarabaeidae. It is one of at least two beetles in this family known as the "rose chafer", the other being the European Cetonia aurata. M. subspinosus occurs from Eastern Canada to Colorado and is considered a pest of many crops and flowers. It is given its common name of rose chafer because it eats the leaves of roses, although it also feeds on many other plants. Order: Coleoptera, Family: Scarabaeidae.
