The Brown Marmorated Stink Bug starts feeding in late May or early June. It feeds on a wide range of fruits, vegetables, and other plants. The adults are approximately 1.5 cm long and the underside is white or pale tan. It sometimes has gray or black markings. The stink glands are located on the underside of the thorax, between the first and second pair of legs. The stinkbug's ability to emit a vile odor through holes in its abdomen is a defense mechanism meant to prevent it from being eaten by birds and lizards. To read more click here.
