External Morphology

Like other Pentatomidae, predatory stink bugs or soldier bugs are of moderate to large size, ranging in length from 7 to 25 mm, and are broadly elliptical in shape. The piercing-sucking mouthparts of predatory stink bugs consist of a four-segmented rostrum or beak (labium) forming a sheath that encloses two mandibular and two maxillary stylets. Whereas the rostrum of phytophagous pentatomids is slender, asopines are characterized by having a thickened rostrum. In asopines, the first segment of the rostrum is markedly thickened and free, which enables the rostrum to swing forward fully, making it easier for the predator to feed on active...
