Eupholus chevrolati is a beautiful species of weevil belonging to the family Curculionidae.
Appearance: This is a relatively small Eupholus species, reaching lengths of about 25 millimeters (0.98 inches). Its base color is a striking metallic blue-green, adorned with irregular black transverse bands along its wing covers (elytra).
