Rice stink bug

The adult Oebalus pugnax measures 0.375 inches (9.5 mm) to 0.50 inches (13 mm) long. It has a narrow profile that forms the shield shape characteristic of other stink bugs. These true bugs are typically straw-colored with sharp points on the apex of the shield and a yellow triangle exhibited on center of the shield. Some adults have gray coloring near the yellow triangle, while others may be a darker brown rather than straw-colored. However, the rice stink bug is easily distinguished from other stink bugs because of its narrower profile and lighter color than, for example, the brown marmorated stink bug.
