The grapevine beetle is characterized by a tan color or a darker shade of brown. Their thick, serrated legs are typically brown or black. Their main distinguishing feature is the presence of dots on their elytra and thorax. Typically, they have 3 dots on each elytron and 1 on the thorax on each side of the body. The point where the thorax joins the abdomen is also characterized by a black or brown semicircle.
